Abstract

The invention discloses a sewage heat energy utilization device, which belongs to a hot water processing device. The sewage heat energy utilization device comprises a heat-preservation tank body which is divided into an upper layer and a lower layer, wherein the upper layer has a cavity serving as a sewage buffer cavity; the upper part of the cavity is connected with a hot water down comer; the sealed lower layer is a pressure-resistance heat-preservation layer; the bottom part of the pressure-resistance heat-preservation layer is provided with a water discharge opening and a cold water inlet; the top part of the pressure-resistance heat-preservation layer is provided with a cold water outlet pipe which passes through the buffer cavity to the outside of the device; and a water discharge pipe running in the pressure-resistance heat-preservation layer connects the buffer cavity and the water discharge opening. The device of the invention can collect the heat energy of sewage, heat cold water, lower the temperature difference to be increased by heating equipment greatly, reduce energy consumption of the heating equipment and have good energy-saving and environment-protection effects.

Description

technical field

[0001] The invention relates to a domestic hot water treatment device, in particular to a water treatment device which can collect and utilize the heat energy in the discharged sewage with high temperature. Background technique

[0002] In daily life, in activities such as bathing and shampooing that use continuous hot water, the hot water at around 40°C that is suitable for the human body is immediately discharged into the sewer after washing. At this time, the temperature of the sewage is still relatively high. Treatment measures, heat energy is wasted.

[0003] Take the traditional water heater hot water supply for shampooing as an example. After turning on the hot water switch, cold water enters the water heater, and then the water heater heats the cold water to an appropriate temperature. After rinsing the hair, it immediately enters the sewer to drain away after a few seconds, and so on. At this time, the temperature of the cold water is basica...
