Waste gas purifiers for FRP industry - Principle of waste gas treatment equipment
For corrosive gas (such as acid, alkaline) waste gas treatment equipment in the use of liquid absorption method. The choice of purification equipment is the key to using liquid to absorb the waste gas. At present, our company has independently developed the purification process and equipment of acid and alkaline waste gas with high purification efficiency, simple operation and management, and long service life. The process and product have the characteristics of simple structure, low energy consumption, high purification efficiency and wide application range. It can effectively remove water soluble gases such as hydrogen chloride gas (HCl), hydrogen fluoride gas (HF), ammonia gas (NH3), sulfuric acid fog (H2SO4), chromic acid fog (Cro3), cyanic acid gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), formalin (HCHO) and so on. The acid mist exhaust gas is introduced into the purification tower by the air duct. After the packing layer, the exhaust gas and the sodium hydroxide absorption liquid are fully contacted for absorption and neutralization reaction. After the acid mist exhaust gas is purified, it is dehydrated and defogged by the defogging board and discharged into the atmosphere by the fan. The absorbent liquid is pressurized by water pump at the bottom of the tower, then sprayed down from the top of the tower, and finally returned to the bottom of the tower for recycling. The purified acid mist exhaust gas meets the local emission standard of Guangdong province, but is lower than the national emission standard.
Waste gas purifiers for FRP industry - Characteristics of waste gas treatment equipment
The equipment adopts packed tower suitable for continuous and intermittent emission of waste gas treatment; The process is simple, the management, operation and maintenance are very convenient and simple, will not cause any impact on the production of the workshop; Wide application range, can purify a variety of pollutants at the same time; The pressure drop is low, the operation elasticity is large, and has the good defogging performance; Purification tower body can be made of FRP/PP/PVC and other materials according to the actual situation; The packing adopts high efficiency and low resistance pall ring, which can completely remove the odor and harmful substances in the gas.
FRP industrial waste gas purifier - waste gas treatment equipment structure
The equipment is divided into single tower body and double tower body. The circular tower body is connected by flanges. It is composed of liquid storage tank, tower body, air inlet section, spray layer, packing layer, swirl mist layer, air outlet cone cap, inspection hole and so on.
FRP industrial exhaust gas purifier - exhaust gas treatment equipment applications
This process and equipment can be widely used in chemical, electronic, metallurgy, electroplating, textile (chemical fiber), food, machinery manufacturing and other industries in the process of acid, alkaline waste gas purification treatment. Such as flavoring food, acid, pickling, electroplating, electrolysis, battery, etc.
