As shown in Figure 1, people’s bathing process is as follows: hot water is obtained after heating, and people do not control hot water during the bathing process. The use of hot water, and the hot water flows away from the drain as sewage. In this bathing method, when the water temperature drops during the bathing process, it is often necessary to heat the bathing water with a large temperature difference of about 20-45°C. In terms of energy, heating each ton of bathing water needs to consume about 28-55kwh of heat energy. In the process of showering, about 30% of the invalid water discharge occurs when the "mixed water" washes hair, soaps, and body washes. At this time, the pollution level of the ground water after bathing is relatively low, and it is easier to treat and reuse, but it is directly drained. The sewage discharged from the road and the toilet is mixed and then discharged. This existing bathing method not only leads to a large waste of water and heat energy resources, but also causes certain pollution to the environment due to the discharged sewage. the

At present, in the existing bathing system, a kind of bathing heating equipment using solar energy is often used. This heating equipment can make good use of the natural energy of solar energy, which greatly reduces the waste of existing energy.

Due to the limited space resources in the city, it is still difficult to apply this large-scale solar heating equipment in a large area in the city, and the process of manufacturing solar heating equipment also consumes a lot of energy. .

Purpose. the

Among them, the reclaimed water treatment system collects the bathing floor water under the pedal type heat recovery device 3, and the sewage first passes through the hair filter to block hair and other large-scale dirt, and then sends the sewage into the air flotation aerator through the sewage pump 41. Under the action of the voltage, the floating aerator precipitates 10-20 micron bubbles with strong oxidation and negative ion characteristics on the two electrodes. Numerous tiny bubbles contact with the sewage in a large area during the floating process, and at the same time play a role in oxidation and sterilization. Organic molecular adsorption and flocculation can achieve the effect of high-efficiency water purification, and then the treated water is pressurized by the water pump 42 to pass through the ultrafiltration membrane 5 after being separated by flocculation foam, and the backwash valve 6 is opened. After disinfection by the sterilizer 7 (ultraviolet, ozone, etc. ) into the reclaimed water storage tank 8 to preserve and wait for use.

When the water level electrodes 23, 24 were conducting, the intelligent controller 22 closed the backwash valve 6. In Fig. 4, 26 is the overflow pipe of the non-pressurized reclaimed water storage tank, which prevents water from being introduced into the sewer when the control fails. the

The intelligent controller determines the start, stop and position of the compressor, three-way valve, electronic expansion valve and fan through the real-time temperature fed back from the 4 temperature measurement points. The start and stop of the water pump and the solenoid valve are determined by the feedback signals from the two water level measurement points and the temperature measurement point. the

In the bathing system of the embodiment, solar energy provides no less than 70% of the energy. The solar energy contribution rate is higher than that of the balcony wall-mounted solar water heater. And because of "10 ℃ bathing", the original energy consumption is reduced by 60%. This means that the ecological bathing water heater can provide the same hot water capacity when the solar heat collecting area and the water tank are reduced by 60% compared with the common solar water heater. The "slimming" of solar water heaters has created excellent conditions for the application of solar energy in cities. It can change the appearance image of the solar water heater, which is large and bulky. It can create a great form and appearance that integrates with the building. Sewage treatment technology uses filtration, flocculation, sewage discharge, disinfection, water storage, and reclaimed water for water supply. Let the bathing water, which accounts for one-third of people's domestic water, be classified and collected for resource treatment, and realize efficient recycling with a small investment for secondary use. the

The essential feature of the bathing system in this embodiment is that the solar heat pump water heater is combined with the heat pump heat recovery device, and the solar heat collector 1 (solar energy and air source evaporator) of the solar heat pump water heater is installed outdoors for solar energy and low-temperature heating in the air. Grade energy collection. The heat pump heat recovery device is installed indoors to quickly recover the heat energy of the bathing water, so that it can be reused nearby. The three-way valve switches the input and output of the solar heat collector and the heat recovery device (indoor and outdoor evaporators). A low-temperature mixing valve is placed between the tap water and the low-temperature water supply pipeline of the mixing valve to keep the water temperature of the low-temperature water supply pipeline at about 30 degrees. The purpose is to reduce the difference between the evaporation temperature and the condensation temperature of the system in the heat pump heat recovery mode The minimum, the system cop value reaches the maximum. When the electronic expansion valve 11 makes the capacity of the system vary from a wide range between 15% and 100%, it ensures that the system always works efficiently. The intelligent controller determines the start, stop and position of the compressor, three-way valve, electronic expansion valve and fan through the real-time temperature fed back from the 4 temperature measurement points. The start and stop of the water pump and the solenoid valve are determined by the signals fed back from the two water level measurement points and the temperature measurement point. The bathing system adopts a metal tubular structure with honeycomb fins through the solar heat collector 1 (solar energy, air source evaporator), and can be added with a forced convection fan. Metal honeycomb fins on metal tubes are installed on the south side of the building at an inclination angle to the local latitude. When there is sunlight, the honeycomb fins can absorb solar energy to the maximum extent, and when there is no sunlight, the metal honeycomb fins can greatly increase the area in contact with the air. Absorb low-grade energy in the air. the

The three-way valve 9 is used for the time-sharing function conversion between the evaporative solar heat collector 1 and the bath floor water pedal heat recovery device 3. The two functions of solar heat collection and energy recovery are a compressor 12 for optimizing the system. Necessary ways to reduce costs. the

Since the thermal energy of bathing ground water is recycled, the energy consumption in the bathing process is greatly reduced. Its main energy comes from solar energy. The characteristics of the circular chain are in line with the ecological concept of establishing a harmonious coexistence between man and nature, so it is called an ecological water heater. the
