Problems solved by technology
However, in practical applications, due to the waste heat of 20°C~30°C in the treated sewage, direct use of treated sewage will result in heat loss.
[0003] It can be seen that in the prior art, there are problems of large heat loss and low energy utilization rate in the sewage treatment process.

The invention relates to a waste sewage heat recycling device which comprises an evaporator, a refrigerant compressor, a condenser, a controller and a water tank, wherein the water tank is provided with a liquid level controller; processed sewage flows through a stop valve and a flow adjusting valve in sequence and subsequently enters the evaporator; an outlet on a primary side of the evaporator is communicated with a sewage pipe network; an inlet on a secondary side of the evaporator is communicated with an inlet on a primary side of the condenser through an expansion valve; an outlet on a secondary side of the evaporator is communicated with the inlet on the primary side of the condenser through the refrigerant compressor; an inlet on a secondary side of the condenser is communicated with a tap water supply network or a heat supply network through a heating circulation pump set and the water tank in sequence; an outlet on a secondary side of the condenser is communicated with a hot water user through the water tank and a water supply pump set; a pressure sensor is arranged at the outlet on the secondary side of the evaporator; and the output end of the controller is connected with the automatic flow adjusting valve. The waste sewage heat recycling device has the characteristics of small heat loss, high energy utilization rate and the like, and can be widely applied to waste heat recycling systems.
Description
technical field [0001] The invention relates to heat recovery technology, in particular to a sewage waste heat recovery device. Background technique [0002] With the increasing urbanization process, the amount of municipal sewage is increasing day by day, and these sewage bring more and more pressure to the normal operation of the city. Under normal circumstances, after the municipal sewage is treated by the sewage treatment method combining physical method, chemical method and biochemical method, the water quality reaches the relevant standard and can be used for cleaning and irrigation. However, in practical applications, since there is residual heat at 20°C to 30°C in the treated sewage, direct use of the treated sewage will result in heat loss. [0003] It can be seen that, in the prior art, there are problems of large heat loss and low energy utilization rate in the sewage treatment process. Contents of the invention [0004] In view of this, the main purpose of th...
