Problems solved by technology

[0003] In the actual sewage heat recovery process, there are a lot of impurities in the sewage discharged by enterprises. If these impurities enter the heat exchanger directly without filtering, it is easy to cause the heat exchanger to be blocked, thereby affecting the heat exchange efficiency.
The filters currently on the market for sewage recovery either cannot meet the requirements of large flow rates, or cannot achieve good filtration effects

Abstract

The invention relates to a filter with a high flow and a good effect. The filter comprises an outer cylinder, a central pipe and a filter net, wherein the outer cylinder comprises a first end plate, a second end plate and a circumferential wall, the central pipe penetrates through the first end plate and enters a filter cavity of the outer cylinder, a first port is formed in the outer end of the central pipe, the inner end of the central pipe is closed, a second port is formed in the second end plate, the central pipe is communicated with the filter cavity through a first circumferential wall hole formed in the circumferential wall, and therefore, a filter channel is formed between the first port and the second port.

Description

technical field [0001] The invention relates to a filter with large flow rate and good effect. Background technique [0002] In printing and dyeing, papermaking, smelting, food and other industries, the amount of water used is astonishing. Water enters the production process at low temperature and is often discharged from nature at high temperature, which takes away a considerable amount of heat energy, resulting in a large amount of energy consumption for production enterprises. So people try to use heat exchange device to recycle the heat energy in sewage, and this kind of device is collectively called sewage heat energy recovery device. [0003] In the actual sewage heat recovery process, there are a lot of impurities in the sewage discharged by enterprises. If these impurities enter the heat exchanger directly without filtering, it is easy to cause the heat exchanger to be blocked, thereby affecting the heat exchange efficiency. The filters currently on the market for s...
