Description

Technical Field

[0001] The invention relates to multi-working-condition air heat and moisture coupling processing equipment, belonging to the technical field of air heat and moisture processes. Background Art

[0002] In air-conditioning projects, different air heat and humidity treatment equipment are required to achieve different air treatment processes. According to different working characteristics, various heat and humidity treatment equipment are divided into two categories: direct contact and surface type. Commonly used surface heat and humidity treatment equipment, such as surface liquid-liquid heat exchangers, can only achieve isohumidification and dehumidification treatment processes in air humidity treatment, and cannot humidify the air. Although the water spray chamber in the commonly used direct contact heat and humidity treatment equipment can achieve a variety of air heat and humidity treatment processes, it has disadvantages such as large size and complex water system. Other commonly used direct contact air treatment equipment needs to set up humidification equipment and dehumidification equipment according to needs when performing air humidity treatment. The air treatment system requires more equipment and the system is more complicated. Summary of the Invention

[0003] In response to the above-mentioned problems, the purpose of the present invention is to provide a multi-condition air heat and moisture coupling treatment device, which can humidify, dehumidify, heat up and cool the air to meet the air heat and moisture treatment requirements under different working conditions.

[0004] The technical solution of the present invention is: a multi-working-mode air heat and moisture coupling treatment equipment, comprising a liquid-liquid heat exchanger, a spray tower, a circulating water pump, a collecting tank, a circulating water collecting device, a solution storage device, a first solution circulating pump, a solution regeneration device, a heating device, a second solution circulating pump, a liquid distribution pipe, and a refrigeration device. The outer circulation outlet end of the liquid-liquid heat exchanger is connected to the liquid distribution pipe of the spray tower, and a collecting tank is installed at the bottom of the spray tower. The outer circulation inlet end of the liquid-liquid heat exchanger is connected to the outlet end of the second solution circulating pump and the circulating water pump respectively through a first solenoid valve and a second solenoid valve, the collecting tank is connected to the inlet end of the solution storage device and the circulating water collecting device respectively through a fourth solenoid valve and a third solenoid valve, and the outlet end of the solution storage device and the circulating water collecting device is connected to the inlet end of the second solution circulating pump and the circulating water pump respectively; the inner circulation inlet and outlet ends of the liquid-liquid heat exchanger are connected to the inlet and outlet ends of the refrigeration device respectively through a ninth solenoid valve and a tenth solenoid valve, and at the same time, the inner circulation inlet and outlet ends of the liquid-liquid heat exchanger are connected to the inlet and outlet ends of the heating device respectively through a seventh solenoid valve and an eighth solenoid valve.

[0005] Furthermore, the other two ports of the solution storage device are respectively connected to a first solution circulation pump and a sixth solenoid valve. The first solution circulation pump is connected to the inlet end of the solution regeneration device through the fifth solenoid valve, and the sixth solenoid valve is connected to the outlet end of the solution regeneration device.

[0006] Due to the adoption of the above technical solution, the advantages of the present invention are: the present invention combines humidification equipment with dehumidification equipment and incorporates heating and cooling devices. According to the needs of the air treatment process, by heating / cooling the spray water / spray metal salt solution, it can achieve humidification, dehumidification, and heating and cooling treatment of the air in a coupled heat and moisture treatment process, meeting the heat and moisture treatment needs of air under different working conditions. Compared with traditional air treatment devices, the present invention utilizes the principle of solution dehumidification to achieve the air dehumidification process, and the refrigeration device is only used to cool the circulating water / circulating metal salt solution. Compared with the traditional cooling dehumidification method that uses a refrigeration device to treat the air to the dew point temperature, it can effectively reduce the operating energy consumption of the air treatment device and reduce the energy consumption of the cold and heat offset in part of the air treatment process.
