With the rapid development of China's economy, especially the continuous and steady development of the machinery industry in recent years, it has brought rare development opportunities to the wind turbine industry. Fan products are among the products with a wide range of applications in various sectors of the national economy. According to surveys conducted by relevant departments, the proportion of wind turbine products used in major industries is: construction accounts for 38.08%, environmental protection accounts for 15.93%, light industry accounts for 7.52%, metallurgy accounts for 6.79%, mine accounts for 6.67%, ships accounts for 4.58%, cement It accounted for 3.96%, electricity accounted for 3.87%, subways and tunnels accounted for 3.79%, textiles accounted for 2.95%, coal accounted for 2.26%, chemical industry accounted for 2.21%, oil accounted for 1.28%, and air separation plants accounted for 0.1%.
However, there are still many areas in which wind turbine products have not been or will be involved, namely the potential market for wind turbine products. So, which areas are the potential markets for wind turbines, and how big is the demand for wind turbines in these markets? It is understood that the demand for wind turbine products in the following areas will increase significantly in the next few years.
Comprehensive utilization of coal gangue After coal gangue was separated from coal in the past, it was piled up as waste, occupying both open space and environmental impact. Turning coal gangue into waste is used to generate electricity. For example, Anhui Huaibei Mining Group Co., Ltd. plans to equip two 75-ton/hour circulating fluidized bed boilers, using 240,000 tons of coal gangue and 100,000 tons of inferior coal. The annual power generation is expected to reach 144 million kWh, requiring boiler ventilators. 6 sets. Similarly, Huozhou Coal and Electricity Group also plans to use coal gangue to generate electricity, and it is estimated that 18 turbines are needed.
The new dry clinker technical transformation project will eliminate the backward wet kiln and adopt advanced technology to build a clinker production line with a daily output of 2,000 tons. After the transformation, each production line can produce 680,000 tons of high-grade cement per year. The heat consumption of clinker burning will be reduced from the current 6294 kJ/kg to 3262 kJ/kg, the comprehensive electricity consumption per ton of cement will be reduced to 110 kW/hr, and the dust emission concentration of kiln exhaust gas will be reduced to less than 100 mg per standard cubic meter. . The project can increase production and reduce consumption and meet environmental protection requirements. A total of 25 ventilators are required for each production line.
The exhaust gas from the flue gas desulfurization thermal power plant boiler contains a large amount of sulfur dioxide, which pollutes the atmosphere. The most serious pollution is acid rain. Therefore, thermal power plants must be equipped with desulfurization devices. Old thermal power plants are not equipped with desulfurization devices and all need to be modified. For example, the Tangshan Power Plant of North China Power Group Corporation plans to use limestone---gypsum wet desulfurization technology to implement flue gas desulfurization reform for 300,000 kW units. After the transformation, the desulfurization efficiency is greater than 95%, and the annual emission of sulfur dioxide is 12,732 tons and the smoke and dust is 4,774 tons.
The flue gas desulfurization device needs a desulfurization fan. Since the sulfur dioxide gas has strong corrosiveness, the difficulty of the desulfurization fan lies in the corrosion resistance of the material, and even the rubber in the impeller is required to prevent corrosion. Many power plants in the country need to carry out desulfurization reform; with the rapid development of the national economy, there are already insufficient power supply in many areas, and new power plants must be built, and new power plants must be equipped with desulfurization devices. Therefore, the potential market for desulfurization fans is large.
Waste incineration combined heat and power production With the increasingly strict environmental protection requirements, urban waste treatment is not limited to waste sanitary landfill and garbage composting. At present, the heat generated by waste incineration has been developed to generate electricity, so-called waste incineration cogeneration. According to statistics, the installation of these units requires 6 sets of wind turbines. Currently, the project is needed everywhere, so the potential market in the country is very large.
Clean coal demonstration project It is understood that Beijing Clean Coal Co., Ltd. intends to rely on existing facilities and use automatic control technology to monitor and control coal blending and molding to achieve advanced demonstration level of clean production in terms of raw material consumption and efficiency. . After the transformation, the coal saving rate is 10%, the sulfur fixation rate is 60%, and the soot emission is reduced by 10%.
A total of 4 ventilators are required for the project.

Reduce the blast furnace gas emission rate to less than 1%. This is both energy efficient and environmentally friendly. The project requires a large number of gas transmission fans and dust removal fans, and the potential market is large.
Blast Furnace Coal Injection Reconstruction In the blast furnace coal injection renovation project, approximately 1 set of 15,000 cubic meters per hour oxygen generator (including air compressors), spray blower and gas collection fan are required.
Dry quenching process In the past, the coke used in the blast furnace of the metallurgical industry adopted the wet quenching process, which wastes energy and causes environmental pollution of the exhaust gas. The dry quenching method uses nitrogen quenching to cool the coke oven, and the residual heat generated is sent to the waste heat boiler for power generation. This requires the fan to vent nitrogen for circulation. The vast majority of steel companies in the country are preparing to launch the project, which is a very large potential wind turbine market.
Clean Gas Chemical Engineering Clean Gas Chemical Engineering uses gas as a raw material to turn it into a liquid and produce fertilizer. Among them, air separation, ammonia compression, etc. require several air compressors, carbon dioxide compressors and ammonia compressors.
The blast furnace gas steam combined cycle device blast furnace gas steam combined cycle device recovers the gas produced by the blast furnace in the metallurgical industry. The device decomposes and vaporizes the gas by distillation, and pressurizes the decomposed hydrogen and nitrogen mixture gas. Into the production of fertilizer raw materials. Centrifugal compressors are required for processes such as pressurization.
According to reports, the process is the recovery of waste gas, which can be described as renewable energy. It not only saves energy, comprehensively utilizes resources, but also reduces environmental pollution and meets environmental protection requirements. It is a promising project. There are many steel companies in the country, so it is a potential market for wind turbines with great development potential.
The co-firing blast furnace gas combined cycle power generation device co-firing blast furnace gas combined cycle power generation device drives the gas turbine with the co-firing gas as a fuel, and the gas compressor is required to pressurize the gas before being sent to the gas turbine. This kind of device is also the development direction of energy-saving comprehensive utilization of many steel enterprises.
Deep processing of fruits and vegetables To make fresh fruits and vegetables fresh or long-term preservation, or to transport them over long distances, it is necessary to shrink the fruits and vegetables. The main measure is to use a fan to charge argon and establish a freezer. The project is an emerging industry and belongs to a large-scale industry. Fan products have broad potential market space in this field.
Greenhouses for greenhouse fans use PVC plastic film or glass windows to form a greenhouse (commonly known as vegetable greenhouses in the north). In the winter season, they are heated by coal stoves or fire walls to increase the temperature of the greenhouse and promote the growth of vegetables. If a fan is installed in the greenhouse to circulate the hot air to achieve a uniform temperature in the greenhouse, the effect will be better. With the development of the national electric power industry (Russian vegetable greenhouses all use electric heating; if electric heating is used in the country, such as charging the electric heat source at the fan outlet, and then automatically switching on and off with the temperature control switch, it will be more ideal), and The gradual improvement of farmers' economic income, the use of fans in the greenhouse for hot gas circulation will certainly be fully promoted. The large number of vegetable greenhouses makes it difficult to make accurate statistics, so the potential market for such wind turbines is incalculable.
Ventilation and ventilation of poultry houses With the continuous development of the breeding industry, poultry houses such as chickens, ducks and geese have gradually become standardized and scientific. Depending on the season, as the temperature changes, the poultry house should be warmed or cooled, and ventilation must be performed. This requires a ventilator (requires low noise). The domestic breeding of poultry houses is huge, so the market potential of such fans is also very large.
Technical transformation of the heat treatment industry At present, the furnace for heat treatment is mainly based on electric heating. Heating with fuel is cheaper than using electricity. Natural gas is the best fuel of choice. The potential for waste gas utilization is great. The recycling of waste gas will use wind turbines, which is a market that has not yet been covered by wind turbines. In the future, the use of natural gas in the heat treatment industry will open up another new market for wind turbines.
The original coal system coking plant of the coking technical transformation project shall be expanded and reconstructed in order to desulfurize gas, purify gas, treat sewage and remove dust. After the transformation, special grade metallurgical coke can be produced, the gas can be partially recycled, and the exhaust gas discharged meets environmental protection requirements. Different types of fans are required for the main process of the project. This coking technical transformation project is available in almost every province in China and is a potential market for wind turbines.
Technical renovation of blast furnace energy saving and consumption reduction It is understood that Angang New Steel Company will build a new 3200 cubic meter blast furnace and eliminate the existing three blast furnaces of No. 3, No. 5 and No. 6 (total volume of 2851 cubic meters). Among the projects related to wind turbines are: hot blast stove, blast station, residual pressure power generation and pulverized coal station. After the transformation, the utilization coefficient of the blast furnace, the ratio of the coke to be burned, the ratio of coal injection, the emission of soot and the utilization of waste energy can be improved. There are a number of steel companies across the country that are required to carry out energy conservation and consumption reduction, thus creating a potential market for wind turbine products.
The smelting environment comprehensively controls the dust removal of the blast furnace tapping yard in the metallurgical industry, the soot treatment of the mixed iron furnace, the treatment and utilization of the converter sludge, and the water quenching treatment of the steel slag. For example, Benxi Iron and Steel Co., Ltd. plans to build a production line of 300,000 tons of water slag powder per year, and build a carbon dioxide recycling production line with an annual output of 10,000 tons. After the transformation, the qualified emission rate of pollutants is ≥94%, the dustfall in the plant area is ≤40 tons/month square kilometers, and the annual recovery of dust is 24,100 tons. Many steel companies in the country need comprehensive environmental management in order to meet environmental protection requirements. This requires a large number of fans for dust removal fans, carbon dioxide recovery, and the like.
Aircraft engine on-board cooling fan After the military aircraft is landed, it needs to be cooled before entering the warehouse. This requires the use of a car cooling fan to quickly cool the aircraft engine with the wind. This is a potential market for wind turbines to be used in military products.
The fish frozen in the cold storage of the fan is used to separate the fish from the ice during the thawing, and the fish is transported to the designated place by a conveyor belt. This type of equipment requires a matching fan to accomplish this task. This is a new area of ​​wind turbine application, which is a potential market.
Each small air separation plant of the steel plant small air separation plant needs to work in tandem with two Roots vacuum pumps (one of the Roots blower manufacturers). At present, small air separation units of less than 10,000 cubic meters per hour nationwide are everywhere, and it seems that the demand for Roots blower products will increase greatly.
In order to reduce the transportation link, the fan for underground coal gasification uses a gasification device to coal gasify underground, and then directly delivers gas to the ground. This system engineering requires a Roots blower to deliver gas. The coal mines are everywhere in the country. If this advanced system engineering is launched in a large number, the potential market for Roots blower products is huge.
Landing boat fans Modern landing craft is actually a small hovercraft. The boat is equipped with a large-power axial fan, which blows air to the water (ground) surface, which causes the boat to generate lift, which requires multiple axial fans. Because this type of fan is a military product, it is a potential fan market with high product quality requirements and technical difficulties.
