High efficiency moisture removal dehumidification device for dehumidifying low temperature storage

Abstract

The present disclosure relates to a dehumidifier for dehumidification of high-efficiency moisture for dehumidifying a low-temperature storage, which may dehumidify supplied humid air using a dehumidifying liquid, use a water seal vacuum pump to bring air into contact with the dehumidifying liquid, and control humidity of the discharged air by sequentially arranging a plurality of pumps and a plurality of chambers in pairs. In addition, there is provided a dehumidifier for dehumidification of moisture in which a dehumidifying liquid is regenerated by using heat generated from a pump inside a device and heat from external equipment.

1 . A dehumidifier using a dehumidifying liquid, comprising:
 a pump having humid air introduced thereinto, receiving the dehumidifying liquid, mixed with air, and transferring the mixture; and   a tank connected to the pump and separate a gas and the dehumidifying liquid,   wherein the pump and the tank are sequentially arranged in plurality in pairs to dehumidify the introduced air.   
     
     
         2 . The dehumidifier of  claim 1 , further comprising:
 a first passage into which the humid air is introduced;   a first pump sucking the air from the first passage, receiving a primary dehumidifying liquid, mixing the air and the primary dehumidifying liquid, and discharging the mixture;   a first tank connected to the first pump, mixing the primary dehumidifying liquid introduced into the first tank with an internal solution and then regenerating the primary dehumidifying liquid, and discharging dehumidified air vaporized under a low pressure environment to a second passage;   a second pump sucking the dehumidified air from the second passage connected to the first tank, receiving a secondary dehumidifying liquid, mixing the secondary dehumidifying liquid with the dehumidified air, and discharging the mixture; and   a second tank connected to the second pump, mixing the secondary dehumidifying liquid introduced into the second tank with the internal solution, and then discharging the dehumidified air to a third passage.   
     
     
         3 . The dehumidifier of  claim 2 , wherein the first pump and the second pump include a water seal vacuum pump, and the second pump creates the connected first tank in a vacuum environment. 
     
     
         4 . The dehumidifier of  claim 3 , wherein the first tank is connected to the first pump and includes a fourth passage supplying the internal solution as the primary dehumidifying liquid to the first pump. 
     
     
         5 . The dehumidifier of  claim 4 , wherein the second tank is connected to the second pump and includes a sixth passage supplying the internal solution as the secondary dehumidifying liquid to the second pump, and the sixth passage passes through the first tank and exchanges heat with the internal solution. 
     
     
         6 . The dehumidifier of  claim 5 , wherein the first tank is further supplied with a heat source from external equipment to exchange heat with the internal solution. 
     
     
         7 . The dehumidifier of  claim 6 , wherein the primary dehumidifying liquid and the secondary dehumidifying liquid contain an aqueous potassium formate solution. 
     
     
         8 . A method of regenerating a dehumidifying liquid including the dehumidifier of  claim 4 , the method comprising:
 collecting an internal solution diluted due to dehumidification in the first tank;   a vaporizing step in which the first tank in a vacuum environment due to the second pump, and the internal solution reaches a boiling point to be regenerated; and   supplying the internal solution as the dehumidifying liquid to the first pump through a fourth passage after the vaporizing step.   
     
     
         9 . The dehumidifier of  claim 8 , wherein the vaporizing step includes a heat exchanging step in which the diluted internal solution receives heat generated from the second pump through a sixth passage. 
     
     
         10 . The dehumidifier of  claim 9 , wherein the vaporizing step includes a heat transfer step of receiving a heat source from external equipment.
