Device for dynamically discharging condensed sewage

Abstract

The invention relates to a device for dynamically discharging condensed sewage in an air pipeline (4) of an aeration tank in the process of sewage treatment. The device comprises a drain pipe (1) and a pressure control valve (3), wherein the lower end of the drain pipe (1) is opened; a gap is reserved between the lower end of the drain pipe (1) and the inner wall of the bottom of the air pipeline (4); and the pressure control valve (3) is arranged at the upper end of the drain pipe (1). The system for dynamically discharging condensed sewage, which is provided by the invention, regulates the pressure by automatically opening the pressure control valve, so that the condensed sewage in the drain pipe is transferred from a liquid phase to a gas phase and is automatically discharged through the drain pipe, and then, the pressure control valve is automatically closed because of the pressure change, thereby preventing the air in the air pipeline from escaping; and when the gap between the lower end of the drain pipe and the bottom of the air pipeline is filled with the condensed water or is clogged by an aerator, the air can also pass through small pipe wall holes on a pipe wall, so that the air can be diffused conveniently when meeting obstructions or can be discharged through the drain pipe, thereby preventing the occurrence of accidents because the air pressure is overlarge.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a dynamic discharge device for condensed sewage in an air pipeline of an aeration tank in sewage treatment. Background technique [0002] As the most important part of the sewage treatment system, the aeration system is the most critical equipment that determines whether the sewage treatment system can operate normally and whether it can meet the discharge standards. At present, most of the urban sewage treatment plants adopt various types of microporous blast aeration process. The energy consumption of the aeration system accounts for about 50-70% of the total electricity consumption of the entire sewage treatment plant, which is the largest energy consumption of the sewage treatment plant. biggest portion. Improving the energy efficiency of the aeration system of the sewage treatment plant and realizing the energy saving and consumption reduction of the aeration system...

Problems solved by technology

This design requires workers to switch the drainpipe valve regularly, which has high requirements for workers, and often does not work well in the actual operation of sewage treatment plants.

Some directly connect the end of the drain pipe to the air pipe, which not only cannot remove the condensed water, but also causes the air to escape.
