Hot water supply device for heat recovery and utilization of hairdressing waste water

Abstract

A hot water supply device for recycling heat energy of hairdressing and beauty waste water comprises a washing basin, a primary filter, a pre-heating tank, a heat pump condensing tank and an evaporation tank and further comprises a secondary filter; the waste water with heat enters a waste water transfer tank after passing through the primary filter and the secondary filter; a tap water inlet pipe is connected with the upper end of a tap water pre-heating coiled pipe in the pre-heating tank; the lower end of the tap water pre-heating coiled pipe is connected with the lower end of the heat pump condensing tank through a warm water connecting pipe; the upper end of the heat pump condensing tank is connected with a water faucet through a hot water outlet pipe; the upper end of a condensing pipe in the heat pump condensing tank is connected with the upper end of an evaporation pipe in the evaporation tank through a condensing connecting pipe and a compressor; the lower end of the evaporation pipe is connected with the lower end of the condensing pipe through an evaporation connecting pipe and a throttling element; the upper end of the evaporation tank is connected with the upper end of the pre-heating tank through a warm waste water connecting pipe; and the lower end of the pre-heating tank is connected with the waste water transfer tank through a waste water pipe and a water pump. The hot water supply device for recycling the heat energy of the hairdressing and beauty waste water, provided by the invention, has the advantages of skillful layout and high efficiency and can continuously provide hot tap water.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a hot water supply device for recovering and utilizing heat energy from waste water in beauty salons. Background technique [0002] At present, in beauty treatment, hairdressing, foot massage, bathing, spa and other industries, hot water devices such as gas, electric heating, and air energy heat pumps are used to produce sanitary hot water. The existing water heaters have the following shortcomings: the thermal efficiency of gas and electric heating devices is very low, and the Large; the thermal efficiency of the air energy heat pump water heating device is relatively high, but it can still be further improved, especially in winter when the air temperature is low, the heating capacity of the air energy heat pump water heating device is greatly reduced, and the thermal efficiency is greatly reduced. It doesn't even work when it's cold enough. The beauty and hairdressing in...

The beauty and hairdressing industry needs a lot of hot water every day. When the temperature is low to a certain temperature, the hot water supply of the water heater is unstable. In order to overcome this shortcoming, people use the heat energy in the waste water to preheat the cold tap water. For a long time, due to the accumulation of dirt, it is easy to cause the blockage of the drainage pipes. For example, in the beauty and hairdressing industry, when hairdressers wash and care people's hair, they generally use hairdressing beds; Hair and dirt are easy to block the drainage pipes, and these hairs and dirt also affect some waste water that needs to be reused or the device installed in the hairdressing bed to recover waste heat from waste hot water, etc.
