Adjustable sewage automatic cooling device

Abstract

The invention provides an adjustable sewage automatic cooling device, and relates to the technical field of sewage treatment. The adjustable sewage automatic cooling device includes a sewage pump connected with a sewage inlet pipe, a cooling part connected with the sewage pump, and a sewage discharge pipe communicating with the cooling part; the cooling part includes a sewage flow channel, an overflow channel and a sewage containing cavity; a centrifugal fan is arranged at the end part of the sewage containing cavity; the sewage pump is connected with the sewage inlet pipe through a suction pipe; the sewage pump is connected with the sewage flow channel through a drainage pipe; the sewage containing cavity communicates with the sewage discharge pipe through a drain pipe; a temperature sensor is arranged at a part where the suction pipe communicates with the sewage inlet pipe; the temperature sensor is electrically connected with a controller; and the controller is electrically connected with the sewage pump and the centrifugal fan. The adjustable sewage automatic cooling device has a simple structure, can effectively cool sewage, has a good cooling effect, and can automatically start and stop the cooling process, the device is not likely to be blocked in the cooling process, and the cooling device is convenient to clean and maintain, and is low in use cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, [0002] In particular, the present invention relates to an adjustable sewage automatic cooling device. Background technique [0003] At present, the pollution of the city is getting more and more serious, and the sewage printing enterprises will generate a large amount of sewage in the production process. In order to save water resources and protect the environment, the sewage needs to be treated and entered into the urban sewage pipe network and reused. Otherwise, it will pollute groundwater and surface water. At present, the biochemical section in sewage treatment is the main process section for removing chemical oxygen demand, ammonia nitrogen and total nitrogen. The biological bacteria in the biochemical section have the best treatment effect at (16-30) ℃, and when the temperature exceeds 43 ℃, the biological bacteria begin to die, so When the temperature of the collected sewage r...

Problems solved by technology

[0004] At present, the cooling device commonly used to control the temperature of sewage mainly sends the high-temperature sewage to the plate heat exchanger through the heat exchange circulating pump, and at the same time sends the cold water provided by the cooling tower to the heat exchanger. After heat exchange, the sewage The temperature drops, so it is necessary to configure a hot water circulation pump with large flow and high power, which increases the energy consumption of the device and increases the working cost

In addition, due to the different components in the sewage, the cooling device will be blocked and the cooling effect will be reduced, and the cooling device is not suitable for cleaning, and the subsequent use cost is relatively high.
