Description

The present invention relates to a water trap and a water removal system including the water trap,

The present invention relates to a water trap and a water removal system including the water trap.

Generally, in the case of a dryer, an evaporator, a concentrator, a deaerator, and an extractor, evaporation water vapor is generated in the inside of the dryer, evaporator, deaerator and extractor.

The evaporated water vapor generated as described above is supplied to a suction device such as a vacuum pump.

In this case, the dryer, the evaporator, the concentrator, the deaerator, and the extractor are connected to the vacuum pump without a separate exhaust means for discharging evaporated water vapor to a vacuum structure.

That is, the evaporated water vapor is introduced into the vacuum pump without any filtering. In this case, the moisture is also introduced into the vacuum pump together, which causes a problem of drastically lowering the life and performance of the vacuum pump.

Therefore, conventionally, a filter for absorbing vaporized water vapor is installed between a dryer, an evaporator, a concentrator, a deaerator, an extractor, and a vacuum pump to remove evaporated water vapor, or a refrigerant and an MEG or PEG-based antifreeze or alcohol- The evaporation water vapor was removed by freezing method to protect the vacuum pump.

However, in the case of removing moisture through the filter, moisture is effectively removed at an early stage, but it falls off into a water vapor and water state in a very short period of time and flows into a vacuum pump.

In the case of removing moisture through a coolant and an antifreeze, the water removal rate is not excellent, and the antifreeze has environmental harmfulness and harmfulness to the human body.

In particular, since the antifreeze can not maintain a cryogenic temperature of -40 ° C or less due to its physical properties, there is a problem that the water can not be frozen except in the form of a full ice.

In addition, alcohol-based materials are not only harmful to the environment and human body, but also have a fire risk, which causes problems of insufficiency of users.

Hereinafter, the present invention will be described in detail with reference to the drawings.

The water trap 1 according to an embodiment of the present invention sucks evaporated water vapor generated in a dryer, an evaporator, a condenser, a defroster, an extractor, etc. having a vacuum structure by a suction unit 120 formed by a vacuum pump, a dry pump, The cooling unit 20 and the fixing unit 30 so that only the air can be delivered to the suction unit 120 by fixing the evaporated water vapor simultaneously with the freezing.

The housing 10 is formed to have a predetermined area and length, and an empty space in which evaporated water vapor is collected is formed therein.

An inlet 11 through which evaporated water vapor is introduced into the lower portion of the housing 10 and an outlet 12 through which air passing through an air passage formed between the fixing portions 30 to be described later is formed do.

At this time, when the inlet 11 and the outlet 12 are located on the same line, the moisture removal rate may be lowered as the evaporated water vapor moves to the outlet 12 at a high speed. Therefore, if the inlet 11 and the outlet 12 are positioned on a diagonal line, the evaporated water vapor collected in the housing 10 can sufficiently pass the cooling part 20 and the fixing part 30, can do.

The cooling unit 20 is for cooling water contained in the evaporated water vapor collected in the empty space of the housing 10 and includes a refrigerant circulation pipe 21 and a refrigerant circulation unit 22.

The refrigerant circulation pipe (21) is installed inside the housing (10), and is formed in a coil shape, and a flow path through which the refrigerant moves is formed.

A refrigerant inlet port 211 is formed at the upper end of the refrigerant circulation pipe 21 and a refrigerant outlet port 212 is formed at the lower end thereof.

The refrigerant circulation unit 22 may include a known refrigeration motor 221 and a radiator 222. The refrigeration motor 221 includes a collection pipe 27 connected to the refrigerant discharge port 212, The radiator 222 includes a refrigeration motor 221 and supply pipes 23 and 24 connected to the refrigerant inlet 211.

That is, the refrigeration motor 221 supplies the refrigerant to the flow path of the refrigerant circulation pipe 21 through the supply pipes 23 and 24 and the refrigerant inlet 211, and the supplied refrigerant flows through the refrigerant circulation pipe 21 And is collected in the freezing motor 221 through the refrigerant outlet 212 and the collecting pipe 27 through the flow path.

The present invention can supply the refrigerant to the refrigerant circulation pipe (21) in an endless circulation manner through the refrigerant circulation unit (22).

When the refrigerant is circulated in the refrigerant circulation pipe 21 as described above, the refrigerant circulates through the heat exchange with the evaporated water vapor existing in the housing 10, and the refrigerant circulation pipe 21 does not have much difference from the refrigerant temperature. Allow to freeze in complete ice form and firmly adhere to the entire surface.

In addition, in the case of removing moisture from a relatively large amount of evaporated water vapor or when the temperature of evaporated water vapor is high, a plurality of refrigerant circulation pipes 21 may be installed in parallel or in series in the housing 10 to improve the water removal rate .

At this time, it is preferable that the temperature of the refrigerant supplied to the refrigerant circulation unit 22 is such that the evaporated water vapor is allowed to freeze in the form of a perfect ice instead of melting, thereby preventing re-evaporation of water.

The fixing part 30 is provided on the outer surface of the refrigerant circulation pipe 21 and has a predetermined length and a predetermined thickness so as to increase the cooling rate of the cooling part 20 while freezing the evaporated water vapor existing in the housing 10, Respectively.

The fixing part 30 conveys the cooling air of the cooling part 20 to heat exchange with the evaporated water vapor present in the housing 10 to cool the fixing part 30, Allow the evaporated water vapor to freeze in the form of a full ice so that it is evenly adhered to the entire surface.

At this time, a plurality of the fixing portions 30 are installed on the outer surface of the refrigerant circulation pipe 21 so that the moisture removal rate is excellent. In addition, the fixing portions 30 are installed in the refrigerant circulation portion 22 so as to be spaced apart from each other by a predetermined distance, thereby forming a passage therebetween.

As a result, the evaporated water vapor is elevated in a state of being distributed evenly through the passages, and the evaporated water vapor is frozen in the process and is fixed to the refrigerant circulation pipe 21 and the fixed portion 30. Accordingly, (12).

In addition, since the evaporated water vapor in the housing 10 is normally sucked through a vacuum pump or the like, the life or performance of the vacuum pump can be prevented from deteriorating as only air is sucked into the vacuum pump.

The fixing part 30 is formed of a thermally conductive material so that the cooling air of the cooling part 20 can be efficiently conducted. The material of the fixing part 30 may be a metal material such as aluminum, copper, stainless steel (SUS) have. In addition, since the coolant circulation pipe 21 is formed as a coil phenomenon, the fixing part 30 intermittently contacts the entire refrigerant circulation pipe 21. Accordingly, the cold air generated in the refrigerant circulation pipe (21) is conducted to the entire refrigerant circulation pipe (21).

That is, when the refrigerant in the refrigerant circulation part 22 flows through the refrigerant inlet port 211 located at the upper end of the refrigerant circulation pipe 21, the lower side of the fixed part 30 which is in contact with the refrigerant circulation part 22 is cooled, At the same time, the cold air of the fixing part 30 is gradually transferred to the upper side, and the cooling air of the fixing part 30 is conducted to the refrigerant circulation pipe 21, It is possible to freeze evaporated water vapor.

In addition, the fixing portion 30 may be formed in a rectangular plate shape as shown in FIG.

The fixing part 30 may be formed in a corrugated shape as shown in FIG. 2, or may be formed in a zigzag shape as shown in FIG. 3, so that the area of contact with the refrigerant circulation pipe 21 may be widened .

Therefore, the fixing part 30 can be cooled by being rapidly transmitted to the cool air of the refrigerant circulation pipe 21, and the cool air generated in the refrigerant circulation pipe 21 can be quickly discharged to the entire refrigerant circulation pipe 21 So that evaporated water vapor can be efficiently iced and fixed.

In this case, the fixing part 30 is shown in a wavy shape or zigzag shape in the drawing, but it is not limited thereto. If the area of contact with the refrigerant circulation pipe 21 is increased and the evaporating water vapor can be efficiently frozen, It is possible.

The waste heat source is supplied to the refrigerant circulation pipe 21 through the refrigerant inlet port 211 and is connected to the refrigerant outlet port 212 and the collection pipe 27 And the refrigerant is recycled to the refrigerant circulation unit 22 through the refrigerant circulation unit 22. When the waste heat source is supplied to the refrigerant circulation pipe 21, the fixing part 30 is also transferred to the fixing part 30 because the fixing part 30 is formed of the thermally conductive material as described above.

This will be described in more detail with reference to FIGS. 4 and 5. FIG.

FIG. 4 is a flow chart showing the operation state when refrigerant is supplied to the refrigerant circulation pipe 21 in the water trap according to the embodiment of the present invention, FIG. 5 is a cross-sectional view of the water trap according to the embodiment of the present invention, The freezing motor 221 and the radiator 222 are connected to each other through the first supply pipe 23 and the radiator 222 is connected to the second supply pipe 24, And is connected to the refrigerant inlet 211 of the refrigerant circulation unit 22. [

The second supply pipe 24 is provided with a capillary tube 26 and the third supply pipe 25 is connected to the first supply pipe 23 and the second supply pipe 24.

The first supply pipe 23 is provided with a first valve V1 for controlling the flow of the refrigerant and the third supply pipe 25 is provided with a second valve V2 for controlling the flow of the waste heat source .

At this time, the first valve V1 and the second valve V2 may be applied as two-way automatic valves.

The refrigerating motor 221 is connected to the refrigerant discharge port 212 of the refrigerant circulation pipe 21 through the collecting pipe 27.

That is, when the evaporated water vapor is to be frozen, the first valve (V1) of the first supply pipe (23) is opened and the second valve (V2) of the third supply pipe (25) The refrigerant is supplied to the radiator 222 through the first supply pipe 23 and then supplied to the refrigerant circulation pipe 21 through the second supply pipe 24 and the capillary 26 to freeze the evaporated water vapor And the refrigerant circulated through the refrigerant circulation pipe 21 is recovered to the freezing motor 221 through the collection pipe 27.

The first valve V1 of the first supply pipe 23 is locked and the second valve V2 of the second supply pipe 25 is closed, When the refrigeration motor 221 is operated after the valve V2 is opened, the waste heat source is supplied to the refrigerant circulation pipe 21 through the first supply pipe 23, the third supply pipe 25 and the second supply pipe 24 And the waste heat source circulated through the refrigerant circulation pipe 21 is recovered to the freezing motor 221 through the collection pipe 27 again.

At this time, a separate valve (not shown) may be further installed in the second supply pipe 24 so that the waste heat source is not supplied to the radiator 222 through the capillary 26.

That is, when the waste heat source is repeatedly circulated through the refrigerant circulation unit 22 to the refrigerant circulation pipe 21, the ice adhered to the refrigerant circulation pipe 21 and the fixing unit 30 is easily thawed, Of the condensed water.

A storage tank (40) is provided below the housing (10) to facilitate the treatment of condensed water.

Specifically, the reservoir 40 is formed to have a constant area and length, and an empty space is formed therein for storing condensed water.

A connection pipe 41 is formed at one side of the upper part of the reservoir 40 to be connected to the inlet 11 of the housing 10. At this time, the inlet 11 and the connection pipe 41 may be coupled to each other in a flange type.

That is, the condensed water dropped from the housing 10 is collected in the reservoir 40 through the inlet 11 and the connection pipe 41.

A drain (42) that is opened and closed through a valve (not shown) is formed at a lower side of the storage tank 40 so that the drain can be drained easily when a predetermined amount or more of condensed water is collected in the storage tank 40.

The condensed water stored in the storage tank 40 may be re-evaporated and may be introduced into the housing 10. In this case, however, the refrigerant is frozen and fixed by the refrigerant circulation pipe 21 and the fixing unit 30, .

When the storage tank 40 is installed in the housing 10, the evaporated water vapor flows into the storage tank 40 through the inlet pipe 43 and then flows into the housing 10 through the inlet 11 of the housing 10, (10).

At this time, the condensation inducing portion 50 is installed in a slant form in the ceiling of the storage tank 40, more specifically, in the vicinity of the inlet pipe 43 and the connecting pipe 41 in the ceiling scene.

That is, the evaporated water vapor introduced through the inflow pipe 43 of the storage tank 40 collides with the condensation induction unit 50 located on the inflow pipe 43 side, is firstly condensed, And is condensed secondarily.

The condensed water generated due to the collision is stored in the storage tank 40, and the remaining evaporated water vapor that has not been condensed is collected in the housing 10.

That is, as the evaporated water vapor in which the water is partially removed in the housing 10 is collected, the water removal efficiency through the refrigerant circulation pipe 21 and the fixing part 30 is improved.

In addition, the condensation inducing portion 50 is installed inclinedly at a position near the inlet 11 and the outlet 12 of the bottom surface and the ceiling surface of the housing 10, more specifically, the bottom surface and the ceiling surface.

That is, the evaporated water vapor introduced through the inlet 11 of the housing 10 collides with the condensation inducing part 50 positioned on the inlet 11 side to be thirdly condensed and then adhered to the refrigerant circulation tube 21 It is possible to make the moisture removal rate more perfect as it collides with the condensation inducing part 50 before being passed through the discharge port 12 and is quaternary condensed.

Next, a moisture removal system according to another embodiment of the present invention will be described.

The water removal system 100 according to another embodiment of the present invention includes a chamber 110, a water trap 1, and a suction unit 120.

The chamber 110 is formed to have a constant area and length and has a vacuum structure.

In this case, the chamber 110 may be a known dryer, an evaporator, a condenser, a defoaming unit, and an extractor. In the figure, the chamber 110 is applied as a vacuum dryer.

Inside the chamber 110, a shelf for placing the object to be dried is provided. The shelves may be installed in layers in the chamber 110 so that a large amount of laundry may be dried at one time.

In addition, an opening / closing door may be formed at one side of the chamber 110 so that the chamber 110 may have a closed structure.

The chamber 110 described above may be a known vacuum dryer for drying the object to be dried through the heat of conduction and radiant heat.

The chamber 110 and the inlet pipe 43 of the storage tank 40 are connected through a first connection pipe 130 and the outlet 12 and the suction port 120 of the housing 10 are connected to each other through a second connection pipe (Not shown).
