Wastewater treatment acid-base dosing device for thermal power plant

Abstract

The invention discloses a wastewater treatment acid-base dosing device for a thermal power plant. The wastewater treatment acid-base dosing device for the thermal power plant comprises a first tank body, a two-way joint and a returning spring, wherein the right side of the first tank body is connected with a second tank body; material feeding openings are mounted at the upper ends of the first tank body and the second tank body; fixing shafts penetrate through the upper surfaces of the first tank body and the second tank body; the lower parts of the fixing shafts are connected with rotating shafts; two air inlet pipes are mounted at the lower ends of the two-way joint; the two air inlet pipes respectively penetrate from the upper surfaces of the first tank body and the second tank body; solenoid valves are mounted outside the air inlet pipes; a gas transmission pipeline is mounted at the upper end of the two-way joint. According to the wastewater treatment acid-base dosing device for the thermal power plant, gas is injected into the tank bodies, so that the stirring of medicine in the tank bodies is facilitated; the gas performs a pressurization effect, the medicine flows out underthe action of the air pressure until the pressure in the tank bodies reverts to a normal pressure state, and discharge pipes are closed, so that a timing material feeding effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of thermal power plant equipment, in particular to an acid-base dosing device for waste water treatment in a thermal power plant. Background technique [0002] In the wastewater treatment of thermal power plants, it is necessary to add acid-base drugs to the wastewater to promote the neutralization reaction between the drugs and the wastewater and reduce the corrosiveness of the wastewater. After the medicine is concentrated in the dosing box, the medicine often precipitates, so that the medicine cannot be evenly put into the boiler, and when adding acid-base medicine to the boiler, it is necessary to manually start and stop the valve, and with the inflow of the medicine, the work The personnel perform timing and close the valve again after a period of time, which has high maintenance costs, and such an operation is easy to forget to close the valve, resulting in excessive influx of medicines and affecting t...
