It can be said that the problem of pesticide residues is a problem that arises with the large-scale use of pesticides. In daily life, it has caused serious problems and impacts on people. Among numerous complaints and consultations by the masses, issues concerning food safety occupies a large area. In recent years, in order to solve the problem of pesticide residues, various localities have actively promoted zero growth plans for pesticides. At the same time, for the safety of agricultural products, the emergence of pesticide residue detectors has provided a rapid and effective method for the detection of pesticide residues. It has become an important tool for ensuring the safety of agricultural products.
In agricultural production, people use pesticides in large quantities in order to pursue good insecticidal effect, quick effect, or good-looking appearance. As a result, the problem of pesticide residues has been widespread in grains, vegetables, fruits, livestock products, and aquatic products. The use of pesticide residue detectors for the rapid detection of these agricultural products not only further regulates the production and trading markets of agricultural products, increases the safety of agricultural products sold on the market, and ensures the safety of people's lives. It is also very important for the development of modern agriculture. Meaning, so from these aspects, the role of pesticide residue detector is very important. At present, there are many brands of pesticide residue detectors on the market, so what is the quality and performance of pesticide residue detectors produced by that company?
The first thing to do is to look at which brand of pesticide residue detector is good. The most important thing is to look at the quality, that is to say, the performance is reliable, the detection efficiency is high, and the precision is high. Topp Yunnong has a professional R&D team, so the pesticide residues in R&D are produced. The professional aspect of the detector is very reliable. In addition, Top Cloud Yunnong is a listed company with obvious brand advantages and a professional after-sales service team that can eliminate the user's worries. Top Top Yunnong pesticide residue detector has been widely used in agricultural pollution-free supervision and inspection center, industry and commerce departments, technical supervision bureaus, health and epidemic prevention stations and other units, and has received unanimous praise.
Combined Flow Closed Cooling Tower
Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.
1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.
2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.
