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 temperature of the cooling water to rise slowly. In addition, if the existing water pressure is not enough, the hot water produced cannot well meet the needs of the users. This requires a more advanced methods and devices to solve the problems in the prior art

Embodiment 1

[0022] 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

[0029] 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-level wastewater reclamation and hot water supply system. The system comprises a sewage pool and a sewage pipe connected with the sewage pool. The sewage pipe is internally provided with multiple levels of heat exchangers used for heat exchange. The multi-level wastewater reclamation and hot water supply system is characterized in that the system further comprises a cold water pipeline; after the cold water pipeline achieves water temperature exchange through the multiple levels of heat exchangers, one end of the cold water pipeline is connected with the top of a heat preservation water tank, and the bottom of the heat preservation water tank is connected with the other end of the cold water pipeline; and the heat preservation water tank is connected with a heat supply heat pump, and the heat supply heat pump is provided with a heating device.

Description

technical field [0001] The invention relates to the field of energy regeneration and recovery, in particular to a multi-stage wastewater recovery hot water supply 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...
