Waste heat recovery system for bathing wastewater

Abstract

The invention discloses a waste heat recovery system for bathing wastewater. The waste heat recovery system comprises a bathing wastewater collection tank; the bathing wastewater collecting tank is connected with a water outlet of a bathroom and is used for collecting bath wastewater; the bathing wastewater collecting tank is connected to a sewage inlet of a plate heat exchanger group through a sewage pipeline; a hair filter and a sewage filter are sequentially mounted on the sewage pipeline; a purified water inlet of the plate heat exchanger group is connected with a tap water inlet through apurified water pipeline; a filter is mounted in the purified water pipeline; a sewage discharge port and a purified water discharge port are formed in the plate heat exchanger group; and the purifiedwater discharge port is connected with a bathing water heat preservation water storage tank. According to the waste heat recovery system, bathing wastewater is reasonably treated, heat in the wastewater can be fully recycled, and bathing water is preheated through waste heat of the wastewater, so that heat waste is reduced, energy is saved, and heating cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bathing, in particular to a waste heat recovery system for bathing wastewater. Background technique [0002] Bathing, i.e. bathing, is a way of cleansing the body. Modern bathing is not just a way of cleaning, but with the progress of society and people's high requirements for health, it has evolved into a sport of health preservation, health care, and light body. Most of them are leisure clubs, business clubs, and holiday hotels. The types of baths are also gradually increasing as people's requirements. Subsequently, the public bathroom has also developed from a simple cleaning place to a club for health care, leisure and entertainment. In the process of bathing, it takes a lot of energy to heat the water. Generally speaking, the water output from the nozzle of the bathing water is about 40 degrees Celsius. After use, it flows to the ground and drops to about 35 degrees Celsius. The waste heat cannot ...
