A waste water treatment acid-base dosing device for thermal power plants

Abstract

The invention discloses an acid-base dosing device for waste water treatment in thermal power plants, which comprises a first box body, a double-way joint and a return spring. The right side of the first box body is connected with a second box body, and both The upper ends of both are equipped with feed inlets, the upper surfaces of the first box body and the second box body are penetrated by fixed shafts, and the rotating shafts are connected below the fixed shafts, and two An air intake pipe, and two air intake pipes penetrate through the upper surfaces of the first box body and the second box body respectively, a solenoid valve is installed on the outside of the air intake pipe, and an air pipeline is installed at the upper end of the two-way joint. The acid-base dosing device for wastewater treatment in thermal power plants injects gas into the tank to facilitate stirring of the medicine in the tank, and the gas acts as a booster. Under the action of air pressure, the medicine flows out until the tank recovers. It is in the normal pressure state, and the discharge pipe is closed, so as to play the role of timing feeding.

Description

Technical field [0001] The present invention relates to the technical field of thermal power plants, in particular a wastewater treatment of acid-base dosing devices for thermal power plants. Background technique [0002] In the wastewater treatment of the thermal power plant, it is necessary to add acid-base drugs in the wastewater to promote the neutralization of the drug and wastewater, and reduce the corrosion of wastewater. After the drug is placed in the pharmaceutical case, the drug often precipitate, so that the drug cannot be uniformly put into the boiler, and when the acid-base drug is added to the boiler, it is necessary to manually start and stop the valve, and with the inflow of the drug The person is counted, and the valve is turned off again after a period of time, and the maintenance cost is high, and such operations can easily forget the valve, causing too much of the drug to inflow, affecting the reactions in the boiler. Inventive content [0003] SUMMARY OF TH...
