Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification systems, in particular to a dehumidification system. Background Art

[0002] Rotary dehumidifiers dehumidify the air through solid hygroscopic materials with high moisture absorption capacity. They have the advantages of a large dehumidification range and high dehumidification efficiency, and have been widely used in the field of air dehumidification. However, since the dehumidification effect of a single rotary dehumidifier is limited and it can only play a preliminary dehumidification role for high-humidity gases, a two-stage rotary dehumidifier is usually designed. However, the regeneration energy consumption of the two-stage rotary dehumidifier is too large and it occupies a large area, so further improvement is needed. Utility Model Content

[0009] The beneficial effect of the utility model is that the dehumidification system of the utility model combines the liquid dehumidification device and the rotary dehumidification device, has a strong dehumidification capacity, and avoids the disadvantage of large regeneration energy consumption of using a two-stage rotary dehumidifier, and can be applied to places requiring deep dehumidification.

[0013] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0014] Please refer to Figure 1 A dehumidification system includes a first cooler, a liquid dehumidifier, a solution heat exchanger, a condenser, a regenerator, an evaporator, a rotary dehumidifier dehumidification zone and a second cooler; the first cooler, the liquid dehumidifier, the second cooler and the rotary dehumidifier dehumidification zone are arranged in sequence along the air supply direction to form an air supply air path; the liquid dehumidifier, the solution heat exchanger, the condenser and the regenerator are connected in sequence, and the regenerator, the solution heat exchanger, the evaporator and the liquid dehumidifier are connected in sequence to form an air supply air path; the evaporator and the condenser are connected to form a refrigerant flow path.

[0015] From the above description, it can be seen that the beneficial effect of the utility model is that the dehumidification system of the utility model combines a liquid dehumidification device with a rotary dehumidification device to achieve deep dehumidification and reduce energy consumption.

[0016] Its air supply path first passes through the first surface cooler to preliminarily cool the fresh air, and then enters the liquid dehumidifier for dehumidification. The initial cooling can improve the dehumidification efficiency of the liquid dehumidifier; the dehumidified air is cooled by the second surface cooler and then enters the dehumidification area of ​​the rotary dehumidifier for deep dehumidification, which can improve the dehumidification efficiency of the rotary dehumidifier.

[0017] In the solution dehumidification flow path, the concentrated solution in the liquid dehumidifier directly contacts the air for heat and moisture exchange, and after absorbing moisture in the air, it becomes a dilute solution; the dilute solution enters the solution heat exchanger, and indirectly exchanges heat with the high-temperature concentrated solution therein to absorb heat, and then enters the condenser to be further heated, and then enters the regenerator to be regenerated and release moisture to become a concentrated solution; the concentrated solution enters the solution heat exchanger as a heat source to indirectly exchange heat with the dilute solution, release heat, and then enters the evaporator to indirectly exchange heat with the refrigerant, further release heat, and finally enters the liquid dehumidifier, thereby realizing the dehumidification cycle of the solution dehumidification flow path. In this cycle, the condenser in the refrigerant flow path is used as a heater to heat the dilute solution, and the evaporator in the refrigerant flow path is used as a solution cooler to cool the concentrated solution, making full use of the cooling and cooling effects of the evaporator and the heating and heating effects of the condenser to achieve the purpose of saving energy consumption.

[0018] Furthermore, it also includes a first filter, a fan, a temperature regulator and a second filter. The first filter, the first surface cooler, the liquid dehumidifier, the second surface cooler, the dehumidification area of ​​the rotary dehumidifier, the fan, the temperature regulator and the second filter are arranged in sequence along the air supply direction to form an air supply air path.

[0019] From the above description, it can be seen that the fresh air is finally sent into the designated space after the temperature is adjusted by the temperature regulator, so that the effect of fresh air temperature control can be achieved.

[0020] Furthermore, it also includes a dilute solution pump and a concentrated solution pump, the liquid dehumidifier, the dilute solution pump, the solution heat exchanger, the condenser, the regenerator and the concentrated solution pump are connected in sequence, and the concentrated solution pump, the solution heat exchanger, the evaporator and the liquid dehumidifier are connected in sequence to form a liquid dehumidification flow path.

[0021] Furthermore, it also includes a throttle valve and a compressor, and the evaporator, the compressor, the condenser and the throttle valve are cyclically connected in sequence to form a refrigerant flow path.

[0022] From the above description, it can be known that the refrigerant exchanges heat with the concentrated solution in the solution dehumidification flow path in the evaporator to form high-temperature refrigerant vapor, which is compressed by the compressor into high-temperature and high-pressure refrigerant vapor, and then discharged into the condenser to condense into high-temperature and high-pressure refrigerant liquid, and then throttled and reduced in pressure by the throttle valve to become low-temperature and low-pressure refrigerant liquid, and enters the evaporator. This reciprocating process achieves the purpose of cyclic refrigeration.

[0023] Furthermore, it also includes a third filter, a regeneration heater, a rotary dehumidifier regeneration zone and a regeneration fan. The third filter, the regeneration heater, the rotary dehumidifier regeneration zone and the regeneration fan are arranged in sequence to form a regeneration air path.

[0024] From the above description, it can be seen that after the exhaust air is filtered by the third filter, it is heated by the regeneration heater, the air temperature rises, and it enters the regeneration area of ​​the rotary dehumidifier to complete the regeneration process, and finally discharged to the outside through the regeneration fan. Setting a regeneration heater before the regeneration area of ​​the rotary dehumidifier can improve the regeneration efficiency.

[0025] Please refer to Figure 1 Embodiment 1 of the utility model is: a dehumidification system, including a first filter 1, a first surface cooler 2, a liquid dehumidifier 3, a dilute solution pump 4, a solution heat exchanger 5, a condenser 6, a regenerator 7, a concentrated solution pump 8, an evaporator 9, a throttle valve 10, a compressor 11, a rotary dehumidifier dehumidification zone 12, a fan 13, a temperature regulator 14, a second filter 15, a third filter 16, a regeneration heater 17, a rotary dehumidifier regeneration zone 18, a second surface cooler 19, and a regeneration fan 20.

[0026] The first filter 1, the first cooler 2, the liquid dehumidifier 3, the second cooler 19, the dehumidification zone 12 of the rotary dehumidifier, the fan 13, the temperature regulator 14 and the second filter 15 are arranged in sequence along the air supply direction to form an air supply air path. The third filter 16, the regeneration heater 17, the regeneration zone 18 of the rotary dehumidifier and the regeneration fan 20 are arranged in sequence to form a regeneration air path. The liquid dehumidifier 3, the dilute solution pump 4, the solution heat exchanger 5, the condenser 6, the regenerator 7, the concentrated solution pump 8 are connected in sequence, and the concentrated solution pump 8, the solution heat exchanger 5, the evaporator 9 and the liquid dehumidifier 3 are connected in sequence to form a liquid dehumidification flow path. The evaporator 9, the compressor 11, the condenser 6 and the throttle valve 10 are connected in a circular manner in sequence to form a refrigerant flow path.

[0027] The operation process of the utility model is:

[0028] The air supply path passes the fresh air filtered by the first filter 1 into the first surface cooler 2 for preliminary cooling, and then enters the liquid dehumidifier 3 for dehumidification; the dehumidified air is cooled by the second surface cooler 19 and then enters the dehumidification area 12 of the rotary dehumidifier for deep dehumidification; the temperature is adjusted by the temperature regulator 14 under the action of the fan 13, and then enters the second filter 15 for filtration, and the fresh air is sent to the designated space.

[0029] The exhaust air duct passes the regeneration air filtered by the third filter 16 into the regeneration heater 17 for heating. The air temperature rises and enters the regeneration area 18 of the rotary dehumidifier to complete the regeneration process. Finally, it is discharged to the outside through the regeneration fan 20.

[0030] In the solution dehumidification flow path, the concentrated solution in the liquid dehumidifier 3 is in direct contact with the air for heat and moisture exchange, and after absorbing moisture in the air, it becomes a dilute solution; the dilute solution enters the solution heat exchanger 5 under the action of the dilute solution pump 4, and performs indirect heat exchange with the high-temperature concentrated solution therein to absorb heat, and then enters the condenser 6 to be further heated, and then enters the regenerator 7 to be regenerated and release moisture to become a concentrated solution; the concentrated solution enters the solution heat exchanger 5 under the action of the concentrated solution pump 8 as a heat source to perform indirect heat exchange with the dilute solution, release heat, and then enters the evaporator 9 to perform indirect heat exchange with the refrigerant, further release heat, and finally enters the liquid dehumidifier 3. In this way, the dehumidification cycle of the solution dehumidification flow path is realized.

[0031] The refrigerant exchanges heat with the concentrated solution in the solution dehumidification flow path in the evaporator 9 to form high-temperature refrigerant vapor, which is compressed by the compressor 11 into high-temperature and high-pressure refrigerant vapor, and then discharged into the condenser 6 to condense into high-temperature and high-pressure refrigerant liquid, which is then throttled and depressurized by the throttle valve 10 into low-temperature and low-pressure refrigerant liquid and enters the evaporator 9. This reciprocating process achieves the purpose of circulating refrigeration.
