Paper making waste gas automatic dosing system spray automatic dosing device

Automatic dosing for papermaking waste gas treatment:

Paper mills generate a large amount of acidic and alkaline waste gases during chemical pulping and bleaching processes. In the process of exhaust gas treatment, the spray tower circulating water tank sprays liquidPHThe value is constantly changing, which seriously affects the adsorption of acidic and alkaline waste gases. In order to ensure that the circulating liquid in the spray tower maintains the corresponding alkalinity（PHvalue in9.00~9.50）Our company's research and development of papermaking waste gasPHThe automatic dosing system can meet the requirements of paper acid and alkali waste gas treatment, achieve unmanned automatic dosing, facilitate enterprises to save labor costs, and meet environmental emission requirements. whenPHValue below9.00At high precisionPHsensorETP-60,Immediately send the model to the instrument panelPC-3300The instrument immediately controls the power supply of the dosing pump to start; whenPHabove9.50At this time, the instrument cuts off the power supply of the dosing pump. Repeat this process repeatedly to achieve automatic adjustment of the acidity and alkalinity of the biological adsorption tower.
