Working principle of Nanchang organic waste gas spray absorption and purification device
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.
Location application
The equipment itself includes a body, a filling layer, a mist layer, a circulating water spray pipe, a circulating water tank, etc..
Spray tower body
The main body of the spray tower comprises an exhaust gas inlet, an outlet, a window, a maintenance hole and a structure used for supporting and fixing in the spray tower, so as to ensure the corrosion resistance of the equipment to increase the service life of the equipment.
Fill layer
Used for 75 Raschig rings, as the spray tower filling material, the material is PP.
For 75 PP Raschig ring with a large surface area, low loss, low height and material transfer characteristics, compared with the filling materials use for 75 PP Raschig rings have higher processing efficiency and low cost of operation.
Mist removing layer
Used for 50 PP hollow spheres as the mist eliminator is made of PP
Circulating water pipe
The pipeline material is PP, the main function is to be sent to the circulating water sprinkler system, and use the nozzle sprinkler system adopts spiral type nozzle, the nozzle is not easy to be blocked, and the spray angle, droplet distribution characteristics, the spray tower can play good effect. ?
Circulating water tank
The circulating water tank is connected with the main body of the spray tower, and the capacity of the water tank is 2-3 minutes, and a float ball type liquid level controller is arranged in the water tank.
Applicable objects: electronic industry, semiconductor manufacturing, PCB manufacturing, LCD manufacturing, metal industry, electroplating and metal processing industry, iron and steel pickling process, dye / pharmaceutical / chemical industry, deodorization / chlorine neutralization and combustion exhaust gas, remove SOx/NOx water soluble air pollution.
Inspection equipment
(1) the tower outlet non blocking, water flow;
(2) to ensure that there is no debris, no ash accumulation; under the circumstances, it is recommended that a week to clean up the sewage outfall;
(3) ensure the additive condition; tower bottom pH control at 7.5-8;
(4) check the water storage tank, replenish the caustic chemicals;
(5) check whether the pump motor heating, abnormal noise, the pump body with no seepage.
When the equipment fails to find the cause of the fault, the individual can solve the problem should be taken immediately; individuals can not be resolved, should promptly notify the responsible personnel and operators. When the need to stop the operation of equipment for maintenance, should first stop the fan, the last stop circulating pump.
Note: due to the different quality and specifications of the equipment, the company will be based on customer demand, professional design and quotation, there is a need for customers, please direct contact
