Description

Technical Field

[0001] This utility model relates to the field of energy-saving device technology, specifically to an energy-saving device for a rotary dehumidifier. Background Technology

[0002] In the pharmaceutical industry, a new type of dual-chamber bag product exists, consisting of a liquid chamber and a powder chamber. Powder dispensing requires a humidity level below 30%, and the relative humidity of the powder dispensing chamber and the powder dispensing isolator is typically controlled by a rotary dehumidifier. Currently, the rotary dehumidifier uses 7°C chilled water for cooling and dehumidification, followed by further dehumidification. This method consumes both chiller electricity and steam.

[0003] It has high energy consumption. The chiller unit runs at full capacity to provide cooling for the air conditioning unit, and all the heat energy of the chiller unit is transferred to the outside through the cooling tower and cannot be recovered and reused. The steam is used to provide heat for the regeneration of the rotor without moving. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an energy-saving device for rotary dehumidifiers, so as to solve the problem that in the prior art, the chiller unit of the rotary dehumidifier is fully turned on to provide cooling capacity for the air conditioning unit, and the heat energy of the chiller unit is transferred to the outside through the cooling tower and cannot be recovered and utilized.

[0005] An energy-saving device for a rotary dehumidifier includes a fresh air duct for fresh air flow and a regeneration air duct for regeneration air flow. An evaporator and a rotary wheel are also installed in the fresh air duct, and the regeneration air duct is connected above the rotary wheel. A condenser is installed at the air inlet of the regeneration air duct, and the air inlet of the condenser is connected to the air outlet of the evaporator, and the air outlet of the condenser is connected to the air inlet of the evaporator.

[0006] The evaporator is used to absorb heat from the fresh air and transfer the heat to the condenser; the condenser is used to preheat the regenerated air, and the regenerated air is used to dehumidify the rotor.

[0007] Furthermore, a first filter screen is provided at the air inlet end of the fresh air duct, and a second filter screen is provided at the air outlet end of the fresh air duct.

[0008] Furthermore, a fan is installed inside the new air duct, which is used to supply air to the air supply end of the new air duct.

[0009] Furthermore, a compressor is installed between the outlet of the evaporator and the inlet of the condenser.

[0010] Furthermore, the evaporator contains refrigerant, and an expansion valve is installed at the evaporator inlet.

[0011] Furthermore, a surface cooler installed in the fresh air duct is provided between the rotating wheel and the second filter screen.

[0012] Furthermore, a steam heater for installation in the fresh air duct is provided between the impeller and the second filter screen.

[0013] Beneficial effects: By using an evaporator to absorb heat from the fresh air and cool it down, the absorbed heat is transferred to the condenser. The condenser then uses this heat to preheat the regenerated air, which in turn dehumidifies the regeneration zone's rotary drum. The gas in the condenser then moves into the evaporator. This circulating flow continuously transfers heat from the fresh air to the regenerated air, recovering and utilizing thermal energy and reducing energy consumption. Attached Figure Description

[0019] like Figure 1The energy-saving device of the dehumidifier with a rotary wheel 6 shown includes a fresh air duct 1 for fresh air flow and a regeneration air duct 12 for regeneration air flow. An evaporator 4 and a rotary wheel 6 are also installed in the fresh air duct 1. The regeneration air duct 12 is connected above the rotary wheel 6. A condenser 7 is installed at the air inlet of the regeneration air duct 12. The air inlet of the condenser is connected to the air outlet of the evaporator 4, and the air outlet of the condenser 7 is connected to the air inlet of the evaporator 4.

[0020] Evaporator 4 is used to absorb heat from the fresh air and transfer the heat to condenser 7; condenser 7 is used to preheat the regenerated air, and the regenerated air is used to dehumidify rotor 6.

[0021] In this embodiment, the evaporator 4 absorbs heat from the fresh air to cool it down and dehumidify it. The heat absorbed in the evaporator 4 is transferred to the condenser 7, which then preheats the regenerated air and dehumidifies the regenerated air in the regeneration zone's rotor 6. Subsequently, the gas in the condenser 7 moves back into the evaporator 4. By utilizing this circulating flow, the heat from the fresh air is continuously transferred to the regenerated air, recovering and utilizing thermal energy and reducing energy consumption.

[0022] The fresh air duct 1 is equipped with a first filter 2 at the air inlet and a second filter 3 at the air outlet.

[0023] In this embodiment, the first filter screen 2 and the second filter screen 3 are configured to filter impurities and prevent impurities from affecting the normal use of the device.

[0024] A fan 11 is installed inside the fresh air duct 1, and the fan 11 is used to supply air to the air supply end of the fresh air duct 1.

[0025] In this embodiment, the fan 11 is a prior art technology used to control the airflow direction and accelerate the movement speed of the air.

[0026] A compressor is installed between the outlet of the evaporator 4 and the inlet of the condenser 7.

[0027] In this embodiment, the compressor is used to compress the gas moving from the evaporator 4 to the condenser 7, generating high-temperature and high-pressure gas, improving preheating efficiency, and better preheating the regenerated air.

[0028] The evaporator 4 contains refrigerant, and an expansion valve 8 is installed at the air inlet of the evaporator 4.

[0029] In this embodiment, the expansion valve 8 is used to cool the gas delivered from the condenser 7. After the coolant is heated, it becomes gas and flows to the condenser 7, and then flows back to the evaporator 4 after being cooled by the expansion valve 8.

[0030] A surface cooler 9 is installed in the fresh air duct 1 between the rotor 6 and the second filter screen 3.

[0031] In this embodiment, the surface cooler 9 is used to cool the dehumidified fresh air and further adjust the temperature and humidity of the dehumidified fresh air.

[0032] A steam heater 10 for installation in the fresh air duct 1 is provided between the rotor 6 and the second filter screen 3.

[0033] In this embodiment, the steam heater 10 is used to heat the dehumidified fresh air and further adjust the temperature and humidity of the dehumidified fresh air.

[0034] Working principle: Fresh air enters the fresh air duct 1 through the first filter screen 2. The evaporator 4 absorbs the heat in the fresh air. The refrigerant in the evaporator 4 is heated and turns into gas. The gas is compressed by the compressor to generate high temperature and high pressure gas. The high temperature and high pressure gas enters the condenser 7 to preheat the regeneration air. The preheated regeneration air heats the liquid on the regeneration zone of the rotor 6 and is removed from the exhaust port of the regeneration air duct 12.

[0035] The fresh air in the fresh air duct 1 is dehumidified by the impeller 6, and after the temperature and humidity are adjusted by the surface cooler 9 and the steam heater 10, it passes through the second filter 3 and is then removed.

[0036] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
