Problems solved by technology

[0002] In the process of dyeing and finishing production, a large amount of high-temperature wastewater is discharged directly without utilization of heat energy, which will lead to two adverse consequences: first, it is discharged into the wastewater treatment pool, which can cause the temperature of the wastewater in the pool to rise to 46°C, which seriously Affects aerobic biochemical treatment, but also needs to be cooled; second, it also causes waste of energy and a large amount of waste of heat energy, which is an important reason for the high production cost

Abstract

The invention relates to a dual-cartridge filter type wastewater thermal energy recovery system comprising dual filter cartridges, a centrifugal pump and a heat exchanger. The water inlet pipes of the dual filter cartridges are inserted into a cesspool through coarse filtration, and the dual filter cartridges are in the manner of parallel connection; and the heat exchanger is provided with a pipeline respectively connected with a clear water inlet and a sewage outlet and further provided with a pipeline connected to a constant pressure hot water pool, and a hand valve is arranged on the pipeline. In the invention, by utilizing the first law of thermodynamics and the second law of thermodynamics, the energy conversion is carried out on the filtered high temperature wastewater and the equivalent cold clear water through the heat exchanger so as to achieve the purposes of raising the temperature of the clear water, saving steams, synchronously reducing the discharge temperature of the wastewater and decreasing subsequent wastewater costs.

Description

technical field [0001] The invention relates to waste water recycling equipment in the textile printing and dyeing industry. Background technique [0002] In the process of dyeing and finishing production, a large amount of high-temperature wastewater is discharged directly without utilization of heat energy, which will lead to two adverse consequences: first, it is discharged into the wastewater treatment pool, which can cause the temperature of the wastewater in the pool to rise to 46°C, seriously It affects the aerobic biochemical treatment, and also needs to cool down; secondly, it also causes waste of energy and a large amount of waste of heat energy, which is an important reason for the high production cost. Therefore, it is very necessary to design a device that recovers heat energy from high-temperature wastewater to regenerate warm water. Contents of the invention [0003] In order to solve the above problems, the present invention provides a dual-tube filter typ...
