It is understood that there are more than 3,000 chemical companies in Wuxi City, of which more than 200 have large-scale sales of over 5 million yuan, and more than 400 have sales of less than 500,000 yuan. Since the beginning of this year, the city has successively counted a number of large and small chemical accidents. Prior to this, the city had regulated and rectified high-risk, small-scale chemical companies with small scale and low efficiency, but it was difficult to implement due to the lack of corresponding laws and regulations.
On May 10 of this year, the Wuxi municipal party committee and municipal government promulgated a local regulatory document "Opinions on Accelerating the Adjustment of Industrial Distribution in the Urban Area." Subsequently, the city's Economic and Trade Commission began implementation in accordance with the spirit of the document and established a “threshold†for chemical companies throughout the city: New chemical projects and enterprises must be settled in the chemical areas planned by the government in the future, and experts are invited to determine the degree of danger and the depth of the process according to the product. , pollution levels and other indicators to develop a scientific access system; the implementation of environmental protection, industry and commerce, safety supervision, fire and other multi-sectoral joint meeting system, harm to society, "problem chemical" and small-scale, low value-added "pocket" chemical companies Blocked. For chemical companies within the “thresholdâ€, the city will gradually move into the chemical park for several years. A 1,000-meter non-residential isolation zone will be set up around the chemical park to ensure the safety of the living environment of nearby residents. At present, the site selection of the chemical industry park is in full swing.
The establishment of a "threshold" does not mean that chemical companies are completely restricted. Ye Yongfu, director of the city's economic and trade commission, said that chemical products such as sulfuric acid, nitric acid, and caustic soda are important raw materials for industrial production, just as cotton is used in the textile industry. Wuxi City has a certain scale and advantages in fine chemicals, so chemical companies have an indispensable role in the industrial economy of Wuxi. For such sustainable enterprises, we still need to support their development.
In the construction of the three-dimensional parking garage, it is often encountered that the self-propelled ramp cannot be used due to the small site. In order to transport the vehicles to different levels for access to the vehicles, it is necessary to use a vertical lift for vehicles. This can replace the ramp for cars to enter and exit the garage, greatly saving space and improving the utilization rate of the garage. This kind of special car elevator is often used for underground or roof and building self-propelled garage to access cars.
