The important role of organic wastewater treatment plant in Nantong
Summary：
SYD type mist purification tower for waste gas treatment in sulfuric acid, nitric acid, hydrofluoric acid, hydrochloric acid and other processes produced in the process of acid gas. SYD type mist purification tower is a tower packed type circular structure of gas-liquid mass transfer. The packing layer is two 25- Phi Phi 38 cascade ring, each main filler is 500 ~ 800mm. This equipment uses spray nozzle cloth. The water retaining plate is 90 degrees, 4 flaps. The treatment tower is composed of three parts: the lower part of a liquid tank section; the middle part of a filling spray and filling spray section; the upper section of a water retaining section. Purification tower with angle steel reinforced frame and maintenance ladder, a liquid pump solution circulation system. The absorption solution is generally 5 ~ 10%NaOH, when the treatment of nitric acid gas, it is recommended to add Na2S solution to improve the purification efficiency.
The equipment is not equipped with exhaust fan, but also can be purchased according to user requirements.
The utility model has the advantages of high purifying efficiency, compact structure, small occupation area, good corrosion resistance, aging resistance, light weight, convenient installation and transportation.
Brief introduction of waste gas washing process:
The basic principle is to use the contact between the gas and the liquid, and the pollutants in the gas transfer to the liquid, and then clean the gas and the contaminated liquid separation to achieve the purpose of clean air.
After the contact of the particulate pollutants in the air stream with the washing liquid, the liquid droplets or liquid films are diffused on the air particles, or the particles are added to the particles so as to achieve the purpose of separation and removal by the action of gravity and inertia force. The gaseous pollutants are transported by the mass transfer such as turbulence, molecular diffusion and chemical reaction into the washing liquid to achieve the purpose of separating from the inlet gas. And can add chemical substances in washing liquid, to absorb gaseous odor control.
The exhaust gas is filled with a washing tower, which is processed by the reverse absorption of the gas and liquid, and the liquid is sprayed down from the top of the tower (downward) in a fog shape (or small water drop). Exhaust gas from the bottom of the tower (reverse flow) to achieve the purpose of gas-liquid contact. This process can reduce the exhaust gas temperature, gas conditioning, and particle removal. And then through the mist treatment (MIST ELIMINATOR) into the atmosphere.
Qingdao San Da environmental technology limited production of waste, waste gas scrubber, waste gas purification tower, spray tower, waste gas treatment equipment, waste gas absorption tower has the following characteristics:
