Description

Technical Field

[0001] This utility model relates to the field of purified drinking water equipment technology, and in particular to an energy-saving fresh air dehumidification condensate water recovery and purification direct drinking water system. Background Technology

[0002] In coastal areas, air humidity is consistently above 70%, and traditional dehumidifiers generate large amounts of condensate that are directly discharged, resulting in resource waste. Existing seawater desalination systems suffer from high energy consumption (5-8 kWh / m³), large equipment size (occupying more than 10 square meters), high operating pressure (5-8 MPa), and high costs when producing drinking water. Furthermore, the moisture and impurities in the air are only 1 / 1000 that of seawater, making it much easier to purify. Summary of the Invention

[0003] To address the aforementioned issues, the present invention aims to provide an energy-saving fresh air dehumidification condensate water recovery and purification direct drinking water system. This system can collect the condensate water generated after dehumidification for use in the production of drinking water, achieving integrated functions of humidity regulation and water resource regeneration, greatly improving energy efficiency and offering high functionality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An energy-saving fresh air dehumidification condensate water recovery and purification direct drinking system is characterized by comprising a fresh air dehumidification module and a water treatment and recovery module; the fresh air dehumidification module includes a housing, and a compressor, a condenser, an electronic expansion valve and an evaporator connected in sequence inside the housing; the housing is provided with an air inlet and an air outlet; the condenser is located near the air outlet, and a fan is provided between the condenser and the air outlet; the evaporator is located near the air inlet, and a water collection tank is provided at the lower end of the evaporator; the bottom of the water collection tank is provided with a condensate water collection pipe extending out of the housing.

[0006] The water treatment and recycling module is located at the bottom of the enclosure and includes a water collection tank, a reverse osmosis water treatment module, and a direct drinking water tank. The other end of the condensate collection pipe is connected to the upper end of the water collection tank. The lower part of the water collection tank is connected to the reverse osmosis water treatment module through a first pipe, which is equipped with a self-priming pump. The reverse osmosis water treatment module and the direct drinking water tank are connected through a second pipe. The direct drinking water tank is connected to the water intake through a third pipe, which is equipped with a water supply pump.

[0007] Preferably, an air filter is fixedly installed inside the housing between the air inlet and the evaporator.

[0008] Preferably, a concentrate recovery pipe is provided above the first pipe, with one end of the concentrate recovery pipe connected to the reverse osmosis water treatment module and the other end connected to the upper end of the water collection tank.

[0009] Preferably, the upper side wall of the water collection tank is provided with an overflow port.

[0010] Preferably, the bottom of the water collection tank is equipped with a drain valve.

[0011] The present invention adopts the above technical solution and has the following beneficial effects:

[0012] ① In the fresh air dehumidification module, after the compressor starts, the refrigerant absorbs a lot of heat when it evaporates in the evaporator, causing the surface temperature of the evaporator to drop. When humid air flows through the evaporator, the moisture in the air condenses into water droplets on the low-temperature evaporator surface, thus achieving the dehumidification effect. A water collection box is set at the bottom of the evaporator to collect condensate, which is then introduced into the water treatment and recycling module. After being purified by the reverse osmosis water treatment module, it can be used for drinking, thereby achieving humidity regulation and drinking water production, greatly improving energy utilization and providing high functionality.

[0013] ② The fresh air dehumidification module uses the principle of heat absorption by the evaporator in the heat pump system for dehumidification, which is more energy-efficient and environmentally friendly.

[0014] ③ This fresh air dehumidification condensate recovery and purification direct drinking water system has a small footprint and is suitable for indoor and outdoor installation. Attached Figure Description

[0021] like Figure 1 An energy-saving fresh air dehumidification condensate water recovery and purification direct drinking system is shown, including a fresh air dehumidification module 1 and a water treatment and recovery module 2. The fresh air dehumidification module 1 includes a housing 3, and a compressor 4, a condenser 5, an electronic expansion valve 6 and an evaporator 7 are sequentially connected inside the housing 3. The housing 3 is provided with an air inlet 8 and an air outlet 9. The condenser 5 is located near the air outlet 9, and a fan 10 is provided between the condenser 5 and the air outlet 9. The evaporator 7 is located near the air inlet 8, and a water collection tank 11 is provided at the lower end of the evaporator 7. A condensate water collection pipe 12 extending out of the housing 3 is provided at the bottom of the water collection tank 11.

[0022] The water treatment and recycling module 2 is located below the housing 3 and includes a water collection tank 13, a reverse osmosis water treatment module 14, and a direct drinking water tank 15.

The direct drinking water tank 15 is connected to the water intake 20 through a third pipe 19. A water supply pump 21 is provided on the third pipe 19.

[0023] In the above technical solution, after the compressor in the fresh air dehumidification module starts, the refrigerant absorbs a large amount of heat when it evaporates in the evaporator after releasing heat through the condenser, causing the surface temperature of the evaporator to drop. The fan system continuously draws humid air through the evaporator, and the moisture in the air condenses into water droplets on the low-temperature evaporator surface, thus achieving the dehumidification effect. A water collection box is set at the bottom of the evaporator to collect the condensate, which is then introduced into the water treatment and recovery module. After being purified by the reverse osmosis water treatment module, it can be used for drinking, thereby achieving humidity regulation and drinking water production, greatly improving energy utilization and providing high functionality.

[0024] Furthermore, the fresh air dehumidification module uses the principle of heat absorption by the evaporator in the heat pump system for dehumidification, with a system COP value of 4.8, making it more energy-efficient and environmentally friendly.

[0025] The main unit of this fresh air dehumidification condensate recovery purification direct drinking system is only 28cm thick, allowing for ceiling mounting. It occupies a total area of ​​1.6㎡, making it small enough to be installed both indoors and outdoors, and suitable for a wide range of applications.

[0026] Furthermore, an air filter 22 is fixedly installed inside the housing 3 between the air inlet 8 and the evaporator 7. In this technical solution, the air filter is used to filter impurities in the air.

[0027] Furthermore, a concentrate recovery pipe 23 is provided above the first pipe 16. One end of the concentrate recovery pipe 23 is connected to the reverse osmosis water treatment module 14, and the other end is connected to the upper end of the collection tank 13. In this technical solution, the inclusion of the concentrate recovery pipe can effectively improve the overall recovery rate of the system and maximize the utilization of water resources.

[0028] Furthermore, the upper side wall of the water collection tank 13 is provided with an overflow port 24. In this technical solution, the overflow port is used to discharge excess liquid to avoid abnormal pressure or leakage due to excessively high liquid level.

[0029] Furthermore, a drain valve 25 is provided at the bottom of the water collection tank 13. In this technical solution, the drain valve drains water from the pipes or equipment in non-operating states or emergencies, preventing freezing, improving system efficiency, and avoiding accidents.

[0032] 2. The compressor starts;

[0033] 3. Condenser for condensation and heat dissipation;

[0034] 4. Electronic expansion valve expands the refrigerant;

[0035] 5. The evaporator absorbs heat from the air. When the gaseous water in the air near the evaporator reaches the dew point temperature, it condenses into liquid water. The liquid water is then collected in the water collection tank through the water collection trough.

[0036] 6. The self-priming pump draws water from the collection tank and sends it to the reverse osmosis water treatment module. The concentrated water from the reverse osmosis water treatment module flows back to the collection tank, and the purified drinking water is stored in the drinking water tank.

[0037] 7. The water supply pump delivers drinking water to the point of use.

[0038] 8. The user turns on the tap to get water.

[0039] It should also be noted that the energy-saving fresh air dehumidification condensate recovery and purification direct drinking water system operates at a relatively low pressure, producing water with a total bacterial count of <10 CFU / mL, making it safer. Furthermore, the water production cost of this solution is 0.8 yuan / ton (compared to 2.5 yuan / ton for seawater desalination), making it relatively cheaper.

[0040] This solution has the following multi-functional features:

[0041] 1. Regulate indoor air humidity.

[0042] 2. Prepare drinking water.
