Description

Dehumidifying agent concentration reducing device for dehumidifying equipment

The present invention relates to a desiccant concentration reducing device for a dehumidifying device, and more particularly to a device for reducing the concentration of a desiccant, which uses a vacuum suction force to reduce the pressure inside the closed vacuum reducing barrel. It is used to reduce the evaporation pressure and evaporation temperature of the diluted desiccant, especially to reduce the reduction temperature required for diluting the desiccant, thereby improving the thermal efficiency of the system and reducing the manufacturing cost and operating cost of the system equipment.

The air conditioning system liquid dehumidification device of the prior art has an absorption device, a reduction device, a heat exchanger, a pump, and a pump is used to deliver the dehumidification solution to the absorption device. The vapor pressure of the dehumidification solution is lower than the vapor pressure of the introduced outdoor humid air. The thermal effect generated by the contact between the two, the dehumidification solution absorbs the moisture in the outdoor humid air to become a dilute solution dehumidifier with a relatively thin concentration, the dilute solution dehumidifier is transported by the pump, and is heated by the heater to increase the temperature of the dehumidification solution, thereby improving Dehumidifying the vapor pressure of the solution, then spraying to the reducing device to exchange heat with the outdoor humid air or indoor exhaust gas, releasing the moisture absorbed in the humid air from the absorption tower into the air, reducing the concentration of the dehumidifying solution, and reducing The environment is carried out under normal atmospheric pressure. Therefore, the reduced diluted solution must be heated before heat exchange with outdoor humid air or indoor exhaust gas to increase the energy level of the desiccant. The heating demand temperature varies depending on the type of the dehumidifying solution used. Generally, the source of the dehumidifying solution needs to be heated at a temperature of about 80 ° C to 120 ° C. The heat source types are generally designed with steam, solar energy, geothermal heat, and compressor compression heat. For example, the International Journal Of Innovative Research Science Engineering And Technology (IJIRSET) on December 1, 2013 discusses experimental analysis of a calcium chloride desiccant dehumidification system. For example, the Australian Solar Energy Society Melbourne December 2012 International Standard Book Number (ISBN): 978-0-646-90071-1 discusses: solar-powered liquid dehumidification systems. For example, IRACST-Engineering Science And Technology: International Journal International Standard Book Number (ISBN) regeneration of dehumidification solution for liquid dehumidification air conditioning systems.

Known dehumidification air conditioning systems have several drawbacks. For example, the dehumidifying system dehumidifying agent has a strong absorption capacity for moisture in the moist air, and also has a strong corrosive force for the metal material. Therefore, the materials of equipment, piping and other components need to be made of non-metallic materials or expensive titanium alloys. Non-metallic materials have corrosion resistance to organic salts, but the fluid temperature is inversely proportional to the pressure resistance of non-metallic materials. The higher the temperature, the lower the withstand voltage. It is known that the high temperature demand for the regeneration and reduction of the concentration of the dehumidifying agent in the chemical dehumidification air conditioning system causes the system equipment to be unstable due to the relationship between temperature and pressure. The reduction temperature requirement of the dehumidification solution of the known chemical dehumidification air conditioning system is higher than that of the general air conditioning heat pump, and is also much higher than the compression heat temperature generated by the general refrigerant compressor. In order to increase the high pressure outlet temperature of the compressor refrigerant, the compression pressure must be increased. Reduce compressor efficiency. Finally, the desiccant reducing device of the prior art reduces the concentration of the desiccant to become a high temperature object, and still has to re-inject the energy to lower the temperature of the object, thereby reducing the overall thermal efficiency of the system.

Therefore, it is necessary to develop a chemical dehumidification air-conditioning device with high heat efficiency, low cost and reliable operation, which separates the cooling and dehumidification of the traditional air conditioner, and the low-temperature and high-energy consumption required for dehumidification of the air-conditioning system is replaced by a dehumidifier, so that the air supply temperature of the air conditioner is improved; The venturi vacuum ejector manufactures a vacuum, so that the pressure in the desiccant reducing barrel becomes a vacuum state, and the dehumidifying agent that has been heated and diluted is sprayed into the reducing barrel, and the diluted desiccant droplets are under vacuum, vacuum pressure The lower the boiling point and vapor pressure of the desiccant, the lower the heat of the moisture absorption dehumidifier itself is evaporated into water vapor, and the water vapor is extracted by the venturi vacuum ejector to reduce the concentration of the dehumidifier, and the vacuum is reduced in the barrel. The temperature of the concentrated solution will lower the temperature of the desiccant solution due to the evaporation heat required to evaporate the droplets of the desiccant, and the temperature drop requirement before the concentrated dehumidifying agent enters the absorption tower.

The desiccant concentration reducing device of the dehumidifying device of the present invention, the desiccant sprinkler of the absorption tower sprays a low-temperature and high-concentration desiccant, and performs heat and mass transfer exchange with the outdoor air in the honeycomb type reaction bed in the absorption tower, and the diluted dehumidification After being heated by the dehumidifier preheat exchanger and the desiccant heater, the agent is sprayed into the evaporation reaction bed in the vacuum reduction barrel, and the water molecules of the desiccant droplets are vaporized to absorb the latent heat of vaporization required for vaporization under vacuum. Water vapor and water vapor pass through a defogging filter to change the direction of water vapor movement, separate and filter water vapor and droplets, and the venturi vacuum ejector continuously extracts water vapor generated in the vacuum reduction barrel to maintain the reduction barrel. The vacuum pressure, after the low pressure, evaporation and cooling dehumidifier flows to the accommodating space at the bottom of the vacuum reduction barrel, and then sent to the desiccant preheat exchanger and the desiccant concentrated solution cooler to be sprayed to the absorption tower by the dehumidification pump. Complete the loop.
