Description
Technical Field
The utility model relates to the technical field of sewage treatment aeration systems, in particular to a high-efficiency control device for drainage of a condensing tube of an aeration system of a sewage treatment plant.
Background
In the operation of a traditional sewage treatment plant, an aeration system is an important component of a biological treatment unit, and the energy consumption of the aeration system is the largest, which accounts for about 50-80% of the operation energy consumption of the whole sewage treatment plant. The traditional aeration mode is mainly divided into mechanical aeration and blast aeration, wherein the mechanical aeration is mainly used for stirring the water surface through a blade or an impeller, so that oxygen in the air continuously enters the water to oxygenate the water body. The blast aeration mainly comprises the steps of conveying air into an aerator through a blast blower and conveying oxygen into a water body in the form of bubbles. With the development of technology, mechanical aeration is gradually replaced by blast aeration due to lower aeration efficiency.
The general underwater aeration equipment is provided with a tubular aerator and a disc aerator, and the inside of the air pipe can condense water due to the change of the temperature difference inside the day-night alternative microporous aerator, so that the air pipe is not smoothly exhausted due to excessive water, and the aeration is not uniform under the condition of untimely discharging of condensed water, and the pressure in the air pipe is increased and the adhesive film is stretched and deformed on the other hand. In addition, the damage of the aeration membrane can lead to easy infiltration of sludge into the pipe, and if the sludge is not discharged together with condensed water, hardening and hardening can thoroughly block the holes. The main maintenance work of the aerator is to periodically discharge condensed water, the depth of a biochemical treatment tank of a sewage plant is generally 4-6 m, and the defect of using the microporous aerator under the condition that the biochemical treatment tank is deeper is that the following 4 points are adopted: and (1) the cost of the underwater microporous aerator is high. (2) The maintenance is complicated, and some air pipe groups need to be integrally lifted for replacement, and other biochemical tanks need to be emptied. And (3) the leakage test is needed after the air pipe is replaced. (4) The aerator is blocked to gradually improve the running pressure of the blower, the service life of the blower can be reduced for a long time, and the extreme situation can lead to the surge of the blower to seriously influence the production running stability. Therefore, if the failure rate of the underwater aerator can be reduced, the running cost can be greatly reduced, and the biochemical tank can be ensured to have a good oxygenation environment.
The general aerator condensate water outlet mode is straight pipe type outflow, the main aerator pipe is DN90 pipe, the condensate water pipe is DN20 branch pipe, the condensate water pipe is generally smaller than the main pipe, the condensate water in the air distribution pipe of the aeration system is sucked through the condensate water pipe by the air stripping principle, the condensate water is extruded in DN20 branch pipe, and the condensate water is discharged by manually and periodically opening the condensate water pipe valve. Firstly, the control is dependent on manual control, so that the randomness is high; secondly, the number of the working loads is large, and the efficiency is low; thirdly, the operation safety is considered, the condensate pipe is generally arranged in the daytime, the condensate pipe cannot be timely and completely discharged, and the control is inaccurate and untimely.
