Water spraying waste gas purification tower, waste gas purification tower
Working principle
The device adopts sodium hydroxide solution to absorb and neutralize liquid to purify waste gas. The gas is pressed into or sucked into the air passage by the centrifugal fan, and then flows upward to the first filling layer. After absorption of the exhaust gas continues to flow upward to the second level of the filler layer, and liquid contact with the second stage nozzle, again reacted according to the indicators of exhaust gas, can be equipped with third filler and spray device, gas purification standards through the mist is discharged into the atmosphere.
Structure and characteristics
The purification tower body is a cylinder type tower body integrally wrapped with glass fiber reinforced plastics. The structure of the utility model is composed of a liquid storage tank, an air inlet section, a three stage spray section, a swirl plate and an air outlet cone cap.
The utility model has the advantages of convenient manufacture, convenient installation and maintenance, high strength and small occupation area. The spray is made of three layers of filler and the spray of the three stage, which makes the gas-liquid contact more fully and improves the purification efficiency. The utility model is equipped with glass steel anti-corrosion centrifugal fan and water pump can. When the processing air volume of 10000 cubic meters or more, the use of two pumps can meet the design requirements.
The equipment can be equipped with gas on-line analyzer, PH control system, a differential pressure transmitter, pressure sensor, flow sensor, conductivity meter, level control meter, electromagnetic valve, inverter and control cabinet and other components of the above control are in the form of digital display interface, make management personnel at a glance, and fault alarm, convenient management and maintenance
