Problems solved by technology

[0003] The existing waste heat recovery system generally exchanges temperature with the cooling water pipe through a multi-stage exchanger, but there are several problems. The heat in the exchanger causes the cooling water temperature to rise slowly, which requires a more advanced method and equipment to solve the problems in the prior art

Embodiment 1

[0020] like figure 1 , is a schematic diagram of the overall structure of the present invention, including a sewage pool 2, the sewage pool 2 is connected with a sewage pipe 3, and the sewage pipe 3 is provided with a slag discharger 4, and the slag discharger 4 includes a housing 4.3, and the housing 4.3 is provided with The sewage inlet 4.2 and the sewage hole 4.4, the sewage enters the housing 4.3 through the sewage inlet 4.2, and the sundries are discharged through the rotating mechanism (driven by the motor 4.1) in the housing 4.3, while the sewage continues to flow in the sewage pipe through the sewage hole 4.4 3 flow, including the first heat exchanger, the second heat exchanger, the third heat exchanger and the fourth heat exchanger in the system, which are arranged in order from left to right. In the above heat exchangers, the sewage pipe 3 Connect with the above-mentioned heat exchanger in turn from left to right; on the right side, there is a cold water pipeline 5, ...

Embodiment 2

[0027] The difference from Embodiment 1 is that the first heat exchanger is provided with a water supply pipeline, and the rest of the working methods and principles are the same as in Embodiment 1.

Abstract

The invention discloses a multi-stage waste water recovery system. The multi-stage waste water recovery system comprises a sewage tank and a sewage pipe connected with the sewage tank. A multi-stage heat exchanger used for heat exchange is arranged in the sewage pipe. The multi-stage waste water recovery system is characterized in that the multi-stage waste water recovery system further comprises a cold water pipe; and after the cold water pipe is subjected to water temperature exchange through the multi-stage heat exchanger, one end of the cold water pipe is connected with the top of a heat insulation water tank, and the other end of the cold water pipe is connected with the bottom of the heat insulation water tank.

Description

technical field [0001] The invention relates to the field of energy regeneration and recovery, in particular to a multi-stage waste water recovery system. Background technique [0002] The water source heat pump hot water system is composed of a water source heat pump hot water main unit independently installed and used by each household and a public water source exchange source. Among them, the household-type water source heat pump hot water hosts are scattered and installed in each household to realize all functions of independent start and stop, and independent control of hot water temperature. Exchange of public water sources, the temperature of the exchanged water sources is low to avoid heat loss in pipeline circulation, which saves the cost of use compared with central hot water supply. Its working principle is to use the raw sewage generated by the house itself, use the waste heat of the raw sewage, use the regenerative energy exchange system and the public exchange...
