注意事项购买酸雾净化塔时应注意，冷库的功能是建立一个低温环境，使腐蚀性产品能够在低温环境中储存，以最大限度地保持食品的原有质量，因此，所有影响仓库内外温度的热量都应为了保证仓库温度的稳定，需要拆除相应的制冷设备。 Precautions for acid mist purification tower When purchasing acid mist purification tower, it should be noted that the function of the cold storage is to establish a low temperature environment, so that corrosive products can be stored in low temperature environment to maximize maintain the original quality of food. In order to ensure the stable temperature of the warehouse, the heat inside and outside the warehouse should be dismantled. The refrigeration capacity produced by the refrigeration equipment should be the inside and outside dimensions of the warehouse, causing fluctuations in the temperature of the warehouse. On this basis, refrigeration compressors and auxiliary equipment should be reconfigured.
In practice, although some methods have high accuracy, they are too complicated to use. Peng Jun's enthalpy difference method or graphic method has been widely used in the calculation of mechanically ventilated FRP cooling towers. When mechanically ventilated FRP is used directly in refrigeration equipment For the tower, the calculation chart in the product sample can be clicked.
Cold loads throughout the year are unstable. Its size is affected by factors such as outdoor temperature, food cooling process requirements, number of cold-processed products, and operation management methods. Therefore, the maximum cooling load of each refrigerating compartment is generally calculated before the cooling load of the warehouse is determined. Then, according to different conditions, the cold load of some cold storage rooms is modified with different coefficients.
The acid mist purification tower has the advantages of high efficiency, strong corrosion resistance, high strength, low noise, low power consumption, small size, convenient disassembly and maintenance, light weight, durability and beautiful appearance.
At present, the liquid phase absorption method is the most commonly used method for treating corrosive gases (such as acidic and alkaline exhaust gas). The key to the liquid phase absorption method for treating exhaust gas is the choice of acid mist purification tower.
The acid mist purification tower is introduced into the purification tower through an air pipe, and through the filler layer, the exhaust gas is fully contacted with the sodium hydroxide absorption liquid and neutralized. After being purified by the acid mist purification tower, the acid mist purification tower is dewatered by the defogging plate and discharged into the atmosphere by a fan. The absorption liquid is sprayed on the top of the tower after being pressurized by the pump at the bottom of the tower, and finally returned to the bottom for recycling. NG.
Secondly, the processing technology of acid mist purification tower was analyzed.
In the acid or alkaline acid mist purification tower , a new type of stepped ring packing (or spherical multi-faceted hollow packing) is built in, and the specific surface area for gas-liquid contact is large. When the exhaust gas passes through the distribution plate, the gas is evenly distributed in the multi-faceted hollow spheres, each of which is in point contact, and moves in the W direction after being arranged to avoid the phenomenon of bias flow. The mixing efficiency is 90% -95%. By spraying and washing the countercurrent absorption liquid (neutralizing liquid H2SO4 or NaOH automatic addition processing device), the harmful gases in the exhaust gas can be removed and the purification effect can be achieved. The harmful gas in the exhaust gas can be removed by adding a neutralizing solution. Generally, there are two-stage spraying devices. Depending on the gas concentration, more spraying device layers can be formed to achieve efficient purification.
