Water power based recycling device for shower wastewater and heat energy

Abstract

The invention discloses a water power based recycling device for shower wastewater and heat energy. The water power based recycling device is a full-automatic comprehensive recycling device for the shower wastewater, which can save the running water and the energy required by heating water, can reduce the quantity of wastewater effluent and can utilize the water power. The hydraulic energy for discharging shower water is utilized as the energy source for collecting the shower wastewater; the shower wastewater after being filtered is pressurized; the shower wastewater enters a heat exchanger through a pipeline; the heat exchanger is utilized to exchange the heat of the collected shower wastewater at higher temperature with the heat of the low-temperature entering water of a shower system, so as to increase the initial temperature of the low-temperature entering water of the shower system; the cooled shower wastewater flows into a recycled wastewater storage device and is used as a water source for flushing a closestool; the shower wastewater is reused, the running water is saved, the sewage discharge and the energy consumption are reduced, and the purpose of saving the energy source and the running water is achieved; the water power based recycling device is safe and reliable and is convenient to realize; and the water power based recycling device has better economic benefit.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and relates to a water saving recycling device, in particular to a hydrodynamic shower waste water and heat recycling device. Background technique [0002] The activities that consume the most water resources in households in daily life are mainly flushing toilets and bathing. Clean tap water is used to flush the toilet in daily life, and it is quite common for bath water with heat to flow to the sewer in vain during bathing. The tap water used is not properly utilized, which is a serious waste of water resources. Therefore, it is an ideal solution to recycle clean domestic water to flush the toilet, which meets the requirements of energy saving, emission reduction and water saving. [0003] The main difficulty in the reuse of domestic bathing sewage is that the sewage is unpressurized water, which contains slag and easily blocks pipes and sanitary equipment. ...

Problems solved by technology

[0004] Patent CN2937258Y discloses a shower device that uses electric energy to recycle shower wastewater, and uses heat exchange to increase the water temperature of the heater to save water and energy consumption. The device uses electric energy as a device for recycling wastewater. Energy consumption not only increases household expenditure and high cost, but also because the shower environment is humid and watery, and people are in direct contact with water during bathing, which will cause potential safety hazards of electric shock; It is not directly used in showers, resulting in low efficiency of heat recovery, complex devices and difficult installation, and it cannot be installed and used for external hot water supply occasions.

Patent CN201276728Y discloses a recycling device that utilizes electric energy to recover the heat of household wastewater and bath wastewater, but also has the disadvantages of power consumption, potential safety hazards, high cost, and inconvenient installation and use.

In the patent CN102322750A and in the patent CN202027484U, a shower waste water heat recovery device is shown. This device is only used to recover the heat of the bath waste water, and the resource recovery is not sufficient.

Patent CN201162253Y introduces a shower room water-saving device using electric energy, which automatically collects shower waste water in the shower room for secondary use, and provides water for toilet toilets; this device only recycles waste water for reuse, and consumes electric energy, which also has potential safety hazards
