Description

Liquid dehumidification device and dehumidification method {Dehumidification System using Liquid Desiccant and Dehumidification Method using the Same}

The present invention is installed in chambers filled with various kinds of gases or air that require dehumidification and temperature control, warehouses or cold storage warehouses for storing various kinds of goods, circulating gas or air inside each chamber or warehouse, and removing moisture. It relates to a liquid-type dehumidifying device and a dehumidifying method configured to

[0002] In air conditioning systems, dehumidifiers have long been used to control humidity in a space.

Recently, with the development of various technologies and industries, the number of technical fields and industries requiring dehumidification and temperature control is increasing.

For example, technology for controlling temperature and humidity in a chamber filled with gas such as hydrogen or natural gas is required, and the demand for low-temperature (refrigeration/refrigeration) distribution centers is increasing due to the increase in online fresh food market demand and diversification of products. It is expected to continue to occur, and as the most important factor to reduce distribution losses, the need for a modern large-scale cold chain infrastructure in an excellent location is emerging more and more.

As such, the demand for chambers or warehouses requiring humidity control is a trend that continues to increase as new industries develop.

Chambers or warehouses used in various industries may deteriorate in performance due to inflow of wet air, and in warehouses where products are stored, the freshness of products is reduced, and poor wet packaging causes hygiene and defect problems, Since the frozen floor causes workers to slip and becomes a factor in safety accidents, the demand for technology to prevent condensation and frost from occurring in chambers or warehouses is continuously increasing.

A method of actively removing condensation and frost by using a refrigerator to remove moisture inside the chamber or warehouse may be considered, but there is a problem in that it is difficult to install a refrigerator in terms of an operating structure in a gas chamber or the like.

Even if a refrigerator can be installed inside a storage warehouse, there is a problem in that a periodic removal management operation is required because frost inevitably occurs on the heat exchanger during dehumidification operation of the refrigerator.

In addition, if there is no separate defrosting operation, there is a problem in that the heat exchanger is completely covered with ice, which rapidly reduces the efficiency of the refrigerator and causes a compressor failure.

In addition, additional dehumidifying refrigerators cause problems in that carbon dioxide (CO2) emissions increase due to increased energy costs and reduced efficiency. There is also a problem against the recent trend of strengthening regulations on the use of refrigerants.

In order to solve this problem, it is required to develop a dehumidifying device capable of actively dehumidifying moisture contained in gas or air inside a chamber or warehouse and having high efficiency.

2 is a block diagram of a liquid dehumidifier according to the present invention.

Referring to FIG. 2 , the liquid dehumidifying device of the present invention includes a dehumidifying module 100 provided inside a chamber or warehouse 1; and a regeneration tank 200 provided outside the chamber or warehouse 1.

The dehumidifying module 100 includes a housing 110; nozzle unit 120; and a first tank 130.

The housing 110 includes an inlet 111 as shown in FIG. 2; outlet 112; and an internal fan 113.

The inlet 111 allows the humid gas or air (Aw) inside the chamber or warehouse 1 to flow into the housing 110, and the outlet 112 to the housing 110 through the inlet 111. Moisture is removed from the introduced gas or air, and relatively dry gas or air (Ad) is discharged.

The internal fan 113 is formed at the outlet 112, and when the internal fan 113 is driven, the gas or air inside the chamber or warehouse 1 flows through the inlet 111 to the housing 110. It flows into the inside and performs a circular motion that is discharged to the outside of the housing 110 through the outlet 112 .

The nozzle unit 120 is configured to inject the dehumidifying liquid f into the housing 110 .

The nozzle unit 120 may be formed at least above the inlet 111 formed in the housing 110, and a plurality of injection ports 121 may be formed according to the width of the housing.

The first tank 130 is formed to store the dehumidifying liquid f capable of adsorbing moisture in the gas or air injected from the nozzle unit 120 and introduced into the housing 110 .

The first tank 130 is located in the lower part of the housing 110, and the dehumidifying liquid sprayed from the nozzle unit 120 is formed on the bottom surface of the housing 110 and the first tank 130. It is preferable that they are configured to communicate with each other so that they flow to the bottom and can be returned to the first tank 130 again.

As shown in FIG. 2 , the first tank 130 and the nozzle unit 120 are connected via a first flow path 910, and the first flow path 910 includes the first tank 130. A first pump 610 capable of moving the dehumidifying liquid to the upper nozzle unit 120 is provided.

Through this configuration, the dehumidifying liquid stored in the first tank 130 can continuously circulate while spraying through the nozzle unit 120 .

The dehumidifying liquid (f) is a liquid having the characteristics of adsorbing moisture contained therein from ambient gas or air at low temperature and releasing water vapor into gas or air at high temperature according to the vapor pressure difference between gas and air. The dehumidifying liquid uses a high-concentration dehumidifying liquid. As the dehumidifying liquid adsorbs more moisture, the concentration of the dehumidifying liquid decreases, and when the concentration falls below a certain level, the dehumidifying efficiency decreases.

The regeneration tank 200 is a component for regenerating the dehumidifying liquid whose concentration is diluted by the dehumidifying action in the first tank 130 .

The dehumidifying liquid diluted in the first tank 130 moves to the regeneration tank 200 along the second flow path 920 by the operation of the first pump 610 . This can be easily implemented by closing the first valve 911 provided in the first passage 910 and opening the second valve 921 provided in the second passage 920 .

Regeneration of the dehumidifying liquid refers to a process of evaporating moisture adsorbed by the dehumidifying liquid to increase the concentration of the dehumidifying liquid, and returning the dehumidifying liquid to a dehumidifying liquid having high dehumidifying efficiency by cooling.

As shown in FIG. 2 , the first heat exchanger 250 is provided in the regeneration tank 200 . By heating the dehumidifying liquid with the first heat exchanger 250 to evaporate moisture, the concentration of the dehumidifying liquid may be increased.

Moisture evaporated from the dehumidifying liquid may be discharged through the fourth flow path 940 as shown in FIG. 2 .

Meanwhile, since the dehumidifying liquid f having a high concentration in the regeneration tank 200 is heated to evaporate moisture, a process of lowering the temperature is required to perform the dehumidifying function.

When cooling the dehumidifying liquid (f) in the regeneration tank 200, natural cooling is possible, but cooling through the first heat exchanger 250 is also possible to cool faster.

This may be implemented by configuring the first heat exchanger 250 as a heat exchanger capable of performing a cooling process as well as a heating process. The heat exchanger may include a member that does not use a separate cooling cycle, such as a thermoelectric element (thermoelectric element), but is not limited thereto.

Next, a second embodiment of the present invention is shown in FIG. 3 .

As shown in FIG. 3 , in the second embodiment of the present invention, a second tank 140 is additionally provided in the dehumidification module 100 .

The second tank 140 is connected to the third flow path 930, receives the dehumidifying liquid f from the regeneration tank 200 or the cooling tank 300, and supplies it to the first tank 130. To store the dehumidifying liquid (f).

The second tank 140 is connected to the first tank 130 through a fifth flow path 950, and in order to regenerate the dehumidifying liquid f of the first tank 130, the regeneration tank 200 Then, the dehumidifying liquid f stored in the second tank 140 is supplied to the first tank 130 so that the dehumidifying process can be quickly performed again in the dehumidifying module 100 .

As such, in the second embodiment of the present invention, since the second tank 140 is additionally provided in the dehumidification module 100, the dehumidifying liquid f can be quickly supplied to the first tank 130, so that the dehumidification process can be performed quickly. In addition, there is an advantage in that the dehumidification process can be smoothly performed even if the regeneration cycle of the dehumidifying liquid f in the first tank 130 is shortened.

Next, FIG. 4 shows a third embodiment of the present invention.

As shown in FIG. 4, the third embodiment of the present invention further includes a vacuum pump 650 capable of lowering the internal pressure of the regeneration tank 100 or creating a vacuum environment.

When the internal pressure of the regeneration tank 200 is lowered, the moisture contained in the dehumidifying fluid (f) can be evaporated at a low temperature, and when the moisture is evaporated at a relatively low temperature, the regenerated dehumidifying fluid (f) can be more easily cooled. there is.

As shown in FIG. 4 , the fourth flow path 940 may be connected to a vacuum pump 650 to lower the pressure inside the regeneration tank 200 or to create a vacuum environment.

The vacuum pump 650 shown in FIG. 4 may be configured as a water ring vacuum pump. When water is used as the working fluid, water stored in the water tank 400 may be used as the working fluid of the vacuum pump 650.

Steam and air inside the regeneration tank 200 are introduced into the vacuum pump 650 through the fourth flow path 940, and water in the water tank 400 is supplied through the seventh flow path 970, Water mixed with air and steam mixed inside the vacuum pump 650 is discharged through the sixth flow path 960 and introduced into the water tank 400 . At this time, a second heat exchanger 450 for cooling may be additionally provided on the seventh flow path 970 .

Through this operation, the internal pressure of the regeneration tank 200 is lowered, a vacuum environment can be created, and moisture adsorbed in the regenerated dehumidifying liquid (f) can be evaporated into water vapor at a low temperature.

Since water vapor is also introduced into the water tank 400 from the regeneration tank 200, the water level in the water tank 400 can gradually increase. You will be able to control it as you release it.

Although FIG. 4 shows a configuration in which a vacuum pump 650 is added to the second embodiment of the present invention having a second tank 140, application to the first embodiment of the present invention shown in FIG. 2 is also shown. It will be possible.

Next, FIG. 5 shows a fourth embodiment of the present invention.

The fourth embodiment of the present invention shown in FIG. 5 is different in that the cooling unit 150 is additionally formed in the dehumidifying module 100.

As shown in FIG. 1, which is a prior art, there is a problem that condensation or frost may occur in the dehumidifying unit when the dehumidifying unit for condensing moisture installed inside the refrigerator corresponding to the chamber or warehouse does not operate, thereby reducing the dehumidifying effect. .

In the present invention, when a conventional heat exchanger is installed in the dehumidification module 100, it may be difficult to maintain the internal temperature of the chamber or warehouse 1 due to the heat generated by the operation of the heat exchanger along with the problem of condensation or frost. this happens

Since the dehumidifying module 100 of the present invention dehumidifies using the desiccant liquid f, there is no need to install a separate heat exchanger, but gas or air is circulated by the desiccant liquid f circulated through the first pump 610. Since (Aw) is dehumidified, the dehumidified gas or air (Ad) discharged through the outlet 112 may have a temperature difference from the temperature of the gas or air inside the chamber or warehouse 1.

Therefore, if the temperature of the dehumidified gas or air (Ad) discharged through the outlet 112 is cooled, the set temperature of the chamber or warehouse 1 can be more easily maintained.

In order to solve this problem, in the present invention, as shown in FIG. 5 , a cooling unit 150 is additionally formed in the outlet 112 provided in the housing 110 .

The cooling unit 150 of the present invention includes a cooling member 151; heat insulating member 52; A heat dissipation space 153 and a heat outlet 154 are included.

As shown in FIG. 5 , the cooling member 151 may be installed on a part or all of the circumference of the outlet 112 to cool gas or air passing through the outlet 112 . For example, if the outlet 112 is in the shape of a duct, it would be preferable to install it along the circumference of the duct.

In the present invention, since the cooling member 151 is installed inside the chamber or warehouse 1, a member that does not use a separate cooling cycle, such as a thermoelectric element, is suitable.

When the cooling member 151 is formed of a thermoelectric element, heat is generated on the rear surface of the cooling member 151. In the present invention, since the cooling member is located inside the chamber or warehouse 1, the chamber or When heat is transferred to the inside of the warehouse (1), the efficiency of the chamber or warehouse (1) is reduced.

The heat insulating member 152 is preferably formed so that the rear surface of the cooling member 151 is completely blocked from the inside of the chamber or warehouse 1. For example, as shown in FIG. 5 , the heat insulating member 152 may be formed in a shape surrounding the outlet 112 while being spaced apart from the outlet 112 .

A heat radiation space 153 may be formed between the cooling member 151 and the heat insulating member 152 .

The heat dissipation space 153 can smoothly dissipate heat generated from the rear surface of the cooling member 151 to the outside through the heat outlet 154 formed on one side.

Meanwhile, it may be possible to additionally form an exhaust fan (not shown) in the heat outlet 154 for more smooth heat dissipation.

Through the configuration of the cooling unit 150, the dehumidified gas or air Ad discharged to the inside of the chamber or warehouse 1 through the outlet 112 is mixed with the gas or air inside the chamber or warehouse 1. It is possible to more smoothly maintain the internal temperature of the chamber or warehouse 1 by controlling the gas or air to have the same temperature or a slight temperature difference.

In addition, since the dry gas or air (Ad) from which moisture has been removed is cooled, there is no concern about condensation or frost during cooling, and cooling or heating can be performed with little energy.

5 shows a configuration in which the cooling unit 150 is added to the dehumidification module 100 of the third embodiment of the present invention shown in FIG. 4, but is not limited thereto, and the present invention shown in FIGS. 2 and 3 It will also be possible to apply to the first and second embodiments of the invention.

In the next step, the first pump 610 is driven so that the dehumidifying liquid f in the first tank 130 is sprayed from the nozzle part 120 via the first flow path 910 and The dehumidifying liquid (f) of (130) is circulated.

In the next step, the internal fan 113 is driven to flow the humid gas or air Aw in the chamber or warehouse 1 through the inlet 111 to the outlet 112 .

At this time, since the desiccant liquid f is sprayed from the nozzle unit 120, the moisture of the humid gas or air Aw introduced into the housing 110 through the intake port 111 is the sprayed desiccant liquid Adsorbed in (f), the dehumidified gas or air (Ad) is discharged through the outlet (112).

In addition, as shown in FIG. 5, when the cooling unit 150 is formed at the outlet 112, the dehumidified gas or air Ad is cooled to the temperature of the gas or air inside the chamber or warehouse 1, discharge

This dehumidification step is repeated until the humidity or moisture content of the gas or air inside the chamber or warehouse 1 reaches a set value.

In the next step, when the concentration of the dehumidifying liquid (f) circulating in the first tank 130 is less than the set concentration, the first flow path 910 is closed and the second flow path 920 is opened. The dehumidifying liquid f in the first tank 130 is transferred to the regeneration tank 200.

In the next step, the dehumidifying liquid (f) moved to the regeneration tank 200 is heated by the first heat exchanger 250 to evaporate moisture from the dehumidifying liquid (f).

4 and 5, when the regeneration tank 200 is connected to the vacuum pump 650, the vacuum pump 650 is operated to lower the internal pressure of the regeneration tank 200 or vacuum. evaporates moisture from the environment;

As described above, in a state in which the internal pressure of the regeneration tank 200 is lowered, as described above, the moisture contained in the dehumidifying liquid f can be evaporated into water vapor even at a relatively low temperature.

In the next step, the dehumidifying liquid f regenerated in the regeneration tank 200 is cooled.

In this step, natural cooling may be performed in the regeneration tank 200, or the dehumidifying liquid f may be cooled using the first heat exchanger 250.

As a next step, there is a step of supplying the dehumidifying liquid f regenerated in the regeneration tank 200 to the first tank 130 or the second tank 140 .

When the dehumidifying module 100 has the second tank 140, the dehumidifying liquid f stored in the second tank 140 is supplied to the first tank 130, and the second tank 140 , the second pump 620 is driven to supply the dehumidifying liquid f from the regeneration tank 200 .

When the second tank 140 is not provided in the dehumidifying module 100, the second pump 620 is driven in the first tank 130 to supply the dehumidifying liquid f from the regeneration tank 200.

After the desiccant liquid (f) regenerated in the regeneration tank 200 is cooled to a sufficiently low temperature, the desiccant liquid (f) regenerated in the regeneration tank 200 passes through the third flow path 930 to the first tank 130. Alternatively, it may be supplied to the second tank 140.

Through these steps, the air inside the chamber or warehouse 1 can be effectively dehumidified.
