AI Technical Summary
When the external humidity of humid gas in existing dehumidifiers is high, the adsorption wheel is prone to excessive adsorption, resulting in poor drying effect.
Before the external humid gas enters the regeneration rotor, it is pretreated through the regeneration heat exchanger and dehumidification unit, including the regeneration heat exchanger, regeneration pipeline, air supply fan, evaporator and molecular sieve rotor. High-temperature and high-pressure gas is used for dehumidification, and low-temperature and low-pressure gas is formed by self-circulation cooling and pressure reduction to achieve self-circulation dehumidification.
It significantly improves the dehumidification effect, ensuring that the regeneration wheel can still effectively absorb moisture under high humidity conditions and achieve efficient drying.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of fresh air systems, and particularly relates to a self-circulating energy-saving and dehumidifying system. Background Art
[0002] As is well known, a dehumidifier is a widely used fresh air device for drying incoming humid air.
[0003] Currently, the dehumidifier includes a regeneration fan, an electric heating module, a regeneration runner, and a drainage structure. After the external humid air enters the dehumidifier, the moisture contained in the humid air is adsorbed through a part of the regeneration runner to achieve a drying effect. Then, the regeneration fan blows the air flow towards this part of the regeneration runner, and the air flow flows through the electric heating module and is heated by the electric heating module. Thus, the heated air flow evaporates the moisture in the regeneration runner and blows it out to the drainage structure, so that the regeneration runner returns to the state before the next adsorption, that is, through the continuous rotation of the regeneration runner, the processes of adsorbing moisture and evaporating moisture are repeated, and the external humid air is continuously dried.
[0004] However, this method has the following deficiencies: The external humid air directly enters the regeneration runner for adsorption. Thus, when the humidity of the external air is relatively high, the regeneration runner may adsorb an excessive amount, that is, it cannot effectively adsorb all the moisture in the humid air, and the drying cannot achieve the expected effect. Content of the Utility Model
[0005] Aiming at the deficiencies of the prior art, the utility model provides a self-circulating energy-saving and dehumidifying system, which can dehumidify the external humid air before it enters the regeneration runner, thus significantly improving the dehumidifying effect.
[0006] To achieve the above object, the utility model provides the following technical solutions:
[0007] A self-circulating and energy-saving dehumidification system, characterized in that it comprises: a regeneration heat exchange unit, including a regeneration heat exchanger and a regeneration pipeline, the regeneration heat exchanger has an input port, one end of the regeneration pipeline is communicated with the input port, and the extending direction of the regeneration pipeline from the input port to the other end is used as the regeneration path; a dehumidification unit, including a dehumidification pipeline, a supply air fan, an evaporator and a molecular sieve rotor, the dehumidification pipeline has a dehumidification inlet and a dehumidification outlet, and the extending direction of the dehumidification pipeline from the dehumidification inlet to the dehumidification outlet is used as the dehumidification path, wherein the molecular sieve rotor has a dehumidification area and a regeneration area, the dehumidification area is located in the dehumidification pipeline, the regeneration area is located in the regeneration pipeline, and the molecular sieve rotor rotates to make the dehumidification area and the regeneration area cycle and transform mutually; the regeneration heat exchange unit further includes a regeneration fan and a heating pipe located in the regeneration pipeline, and the regeneration fan, the heating pipe and the regeneration area are arranged in sequence along the regeneration path, and the supply air fan, the evaporator and the dehumidification area are arranged in sequence along the dehumidification path; the self-circulating and energy-saving dehumidification system further includes a phase change component, and the phase change component includes a compressor and a capillary tube, the input of the compressor is communicated with the output of the evaporator; the output of the compressor is communicated with the input of the heating pipe; the input of the capillary tube is communicated with the output of the heating pipe; the output of the capillary tube is communicated with the input of the evaporator.
[0008] Preferably, the supply air fan, the evaporator and the dehumidification area are all arranged on the dehumidification pipeline.
[0009] Preferably, the regeneration heat exchanger further has an exhaust port, the other end of the regeneration pipeline is communicated with the exhaust port, and the regeneration path extends from the input port to the exhaust port.
[0010] Preferably, the regeneration heat exchanger is a sensible heat exchanger and has a condensate drain pipe.
[0011] Compared with the prior art, the beneficial effects of the present utility model are:
[0012] 1. Since the self-circulating power consumption reduction and dehumidification system of the present utility model includes a regeneration heat exchange unit, a dehumidification unit, and a phase change component, the regeneration heat exchange unit includes a regeneration heat exchanger, a regeneration pipeline, a regeneration fan, and a heating pipe. The regeneration heat exchanger has an input port, and the extending direction in the regeneration pipeline is taken as the regeneration path. The dehumidification unit includes a dehumidification pipeline, a supply air fan, an evaporator, and a molecular sieve rotor. The dehumidification pipeline has a dehumidification inlet and a dehumidification outlet, and the extending direction from the dehumidification inlet to the dehumidification outlet in the dehumidification pipeline is taken as the dehumidification path. The molecular sieve rotor has a dehumidification area and a regeneration area located in the dehumidification pipeline and the regeneration pipeline respectively. The regeneration fan, the heating pipe, and the regeneration area are arranged in sequence along the regeneration path, and the supply air fan, the evaporator, and the dehumidification area are arranged in sequence along the dehumidification path. The phase change component includes a compressor, and the evaporator, the compressor, the heating pipe, and the capillary tube are output-coupled in sequence. The compressor outputs high-temperature and high-pressure gas, and the high-temperature and high-pressure gas flows through the heating pipe internally. When the air flow in the regeneration pipeline flows through the heating pipe, it exchanges heat with the high-temperature and high-pressure gas, thereby forming a heated air flow blowing towards the regeneration area. The high-temperature and high-pressure gas after heat exchange is depressurized and cooled through the capillary tube to form low-temperature and low-pressure gas flowing into the evaporator. The external humid gas enters the evaporator through the supply air fan, exchanges heat with the low-temperature and low-pressure gas, thereby forming a coolant flowing into the compressor and becoming the refrigerant of the compressor. Therefore, the present utility model can dehumidify through the evaporator before the external humid gas enters the molecular sieve rotor, thereby significantly improving the dehumidification effect, and the cooling water generated by the evaporator forms the cold of the compressor, thereby realizing the phase change process of the self-circulation of liquid-gas phase change.

Detailed Embodiments
[0015] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the following embodiments will specifically describe the self-circulating power consumption reduction and dehumidification system of the present utility model in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model.
[0016] As Figure 1 shown, the self - circulating energy - saving and dehumidifying system 100 in this embodiment includes a regenerative heat exchange unit 10, a dehumidifying unit 20, and a phase - change component 30.
[0017] The regenerative heat exchange unit 10 includes a regenerative heat exchanger 11, a regenerative pipeline 12, a regenerative fan 13, and a heating pipe 14.
[0018] The regenerative heat exchanger 11 is a sensible heat exchanger, having an input port 111, an exhaust port 112, and a condensate drain pipe 113. Specifically, the regenerative heat exchanger 11 has a first environment side and a second environment side, and the environments on the first environment side and the second environment side are different. The first environment side has an inlet port (not shown in the drawings) and an outlet port (not shown in the drawings), and the second environment side has an input port 111 and an exhaust port 112. In this embodiment, both the inlet port and the outlet port open to the open environment.
[0019] Both ends of the regenerative pipeline 12 are respectively connected to the input port 111 and the exhaust port 112. The extension direction from the input port 111 to the exhaust port 112 in the regenerative pipeline 12 is taken as the regeneration path P1. Specifically, the environmental side air flow on the first environment side enters the regenerative heat exchanger 11 through the inlet port for heat exchange, and then the environmental side air flow enters the regenerative pipeline 12 through the input port 111 at a first predetermined stable temperature range to form a regeneration air flow. The regeneration air flow flows along the regeneration path P1 to the exhaust port 112, enters the regenerative heat exchanger 11 for heat exchange, and finally the regeneration air flow flows back into the first environment side through the outlet port at a second predetermined temperature range.
[0020] Both the regenerative fan 13 and the heating pipe 14 are located in the regenerative pipeline 12. Specifically, the regenerative fan 13 is used to make the regeneration air flow flow stably along the regeneration path P1 in the regenerative pipeline 12. The heating pipe 14 is a hollow coiled pipe, and the heating pipe 14 has an inlet end and an outlet end.
[0021] Specifically, the condensate drain pipe 113 opens to the first environment side and is used to discharge the condensate generated during the sensible heat exchange process.
[0022] The dehumidifying unit 20 includes a dehumidifying pipeline 21, a supply air fan 22, an evaporator 23, and a molecular sieve rotor 24.
[0023] The dehumidifying pipeline 21 has a dehumidifying inlet 211 and a dehumidifying outlet 212. The extension direction from the dehumidifying inlet 211 to the dehumidifying outlet 212 in the dehumidifying pipeline 21 is taken as the dehumidifying path P2. Specifically, humid gas flows into the dehumidifying inlet 211, and dry gas flows out of the dehumidifying outlet 212.
[0024] The molecular sieve rotor 24 has a dehumidification area 241 and a regeneration area 242. The dehumidification area 241 is located in the dehumidification duct 21, and the regeneration area 242 is located in the regeneration duct 12. The molecular sieve rotor 24 rotates to cause the dehumidification area 241 and the regeneration area 2452 to cyclically transform into each other. Specifically, there is also a drive motor (not shown in the drawings) in the dehumidification duct 21 to drive the molecular sieve rotor 24 to rotate. In this embodiment, some pipe segments of the dehumidification duct 21 and some pipe segments of the regeneration duct 12 are straight and adjacent in parallel, and are connected through a communication port. The molecular sieve rotor 24 passes through this communication port, so that the molecular sieve rotor 24 is simultaneously located in some pipe segments of the dehumidification duct 21 and some pipe segments of the regeneration duct 12, and the molecular sieve rotor 24 is perpendicular to both some pipe segments of the dehumidification duct 21 and some pipe segments of the regeneration duct 12. Therefore, when the drive motor drives the molecular sieve rotor 24 to continuously rotate, the regeneration area 242 and the dehumidification area 241 in the regeneration duct 12 and the dehumidification duct 21 continuously cycle and transform into each other.
[0025] The air supply fan 22, the evaporator 23, and the dehumidification area 241 are all arranged on the dehumidification duct 21, and the air supply fan 22, the evaporator 23, and the dehumidification area 241 are arranged in sequence along the dehumidification path P2. The regeneration fan 13, the heating pipe 14, and the regeneration area 242 are arranged in sequence along the regeneration path P1.
[0026] The phase change component 30 includes a compressor 31 and a capillary tube 32.
[0027] The input of the compressor 31 is connected to the output of the evaporator 23; the output of the compressor 31 is connected to the input of the heating pipe 14; the input of the capillary tube 32 is connected to the output of the heating pipe 14; the output of the capillary tube 32 is connected to the input of the evaporator 23.
[0028] The cyclic transformation process of the refrigerant and the heat medium in the compressor 31, the heating pipe 14, the capillary tube 32, and the evaporator 23 will be specifically described in combination with the embodiments:
[0029] The evaporator 23, the compressor 31, the heating pipe 14, and the capillary tube 32 are sequentially output-coupled. The compressor 31 outputs high-temperature and high-pressure gas, and the high-temperature and high-pressure gas flows into the heating pipe 14 through the inlet end. When the regeneration air flow in the regeneration pipeline 12 flows through the heating pipe 14, it exchanges heat with the high-temperature and high-pressure gas through the heating pipe 14, thereby heating up and blowing towards the regeneration area 242. The high-temperature and high-pressure gas after heat exchange cools down and flows to the capillary tube 32 through the outlet end. The cooled high-temperature and high-pressure gas forms low-temperature and low-pressure gas after decompression and temperature reduction through the capillary tube 32, and flows into the evaporator 23. The humid air flow flowing in from the dehumidification inlet 211 enters the evaporator 23 through the air supply fan 22, exchanges heat with the low-temperature and low-pressure gas in the evaporator 23, thereby forming a coolant in the evaporator 23. This coolant flows into the compressor 31 and becomes the refrigerant of the compressor 31, and then the above process is repeated to realize the self-circulation process of the liquid-gas phase change among the evaporator 23, the compressor 31, the heating pipe 14, and the capillary tube 32.
[0030] The above embodiments are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by those of ordinary skill in the art without creative labor within the scope of the appended claims still fall within the protection scope of this patent.
