The present invention relates to a condensation system for the recovery of organic solvents used in various clothes dryers, and more particularly, to select high-temperature steam or air supply through the condenser or direct discharge into the atmosphere depending on the presence or absence of organic solvents. The bag filter and the plate-shaped filter are detachably installed on the upper side of the shutter-type distribution chamber to minimize the debris attached to the surface of the distribution chamber and the shutter or directly discharged into the atmosphere. And to contribute to the prevention of environmental pollution.

In addition, the present invention is to dualize the radiator connected to the compressor and the condenser to the main radiator and the auxiliary radiator to reheat the air dried in the system by the main radiator, so that the electric heat or hot water heating method It is possible to supply the drying air of the laundry needed for the clothes dryer only by the circulation method of the refrigerant without applying the above, and thus it is possible to contribute to the efficient recycling of energy and the cost reduction according to the equipment of the clothes dryer.

In addition, the present invention by providing a guide vane close to the sensor in accordance with the air pressure of the exhaust air on the passage of the air discharged to the outside of the system to automatically turn on (ON) / off (OFF) operation of the system by The internal pressure of the airtight casing can be adjusted according to the situation by using the check damper which can control the opening and closing amount of the airtight casing which makes up the system. It is about ensuring the safety of using the system by proactively blocking the risks that can occur if they are much lower or exceed the threshold.

In particular, the present invention can be installed in a heat exchanger adjacent to the condenser to perform a heat exchange with the hot steam introduced into the system or the air discharged from the primary air discharged from the main heat radiator or the air cooled and dried in the condenser. In this way, the temperature of steam or air in contact with the surface of the condenser is relatively lowered, and the temperature of the drying air discharged to the outside of the system can be relatively increased, thereby minimizing the load of the compressor to minimize the load on the system. The present invention relates to maximizing the recovery rate of the organic solvent and the recycling rate of energy while making a greater contribution to stable and smooth operation, and to shortening the drying time of the laundry by the clothes dryer as much as possible.

Generally, the organic solvent refers to a liquid as a mixed material capable of dissolving other substances, and is widely used as a solvent in clothes dryers and various printing related companies used in dry cleaning equipment of a laundry. In addition, when released into the air in the form of air, not only harmful to the human body but also generate various volatile organic compounds (VOC) that cause air pollution.

Therefore, in the case of steam or air containing organic solvents, a separate treatment device should be used to release the organic solvents to the atmosphere in a state where organic solvents are removed. In a relatively large company, volatile organic compounds are used as activated carbon filters to remove such organic solvents. After the adsorption, hot air is added to the activated carbon filter to drop it out, and then expensive equipment is used to finally remove volatile organic compounds by high temperature heating and catalytic reaction.

However, it is almost impossible to install and operate such an expensive treatment facility in a small, self-owned small business such as a laundry machine. After inserting into the sealed casing, by supplying steam or air containing the organic solvent to the inside of the casing, a system for condensing, recovering and recycling the organic solvent has been developed and used.

As a system for recovering the organic solvent as described above, a compressor and a radiator are fixedly installed together with a control panel outside the sealed casing, and a condenser connected to the compressor and the radiator by a refrigerant pipe is installed inside the sealed casing. The inlet pipe, the first discharge pipe and the pressure regulating pipe by the damper and the second discharge pipe are connected to the front wall of the casing, respectively. The space is sequentially formed, and the remaining inner space including the condenser is formed as a discharge space in communication with the pressure control tube and the second discharge pipe, the steam introduced into the interior of the closed casing through the inlet pipe The air communicates with the first induction space or the first discharge pipe which communicates with the distribution space by the lower side diaphragm. Distributing chamber is installed to selectively open and close the inlet passage formed in the front, rear side so as to guide to the second guide space, the shutter is in accordance with the rotation operation of the shutter handle installed on the outside of the closed casing The distribution plate is provided to selectively open and close both inflow passages of the distribution chamber, the distribution plate forming the distribution space is formed through the dispersion hole through the front surface of the body, the interior of the distribution space corresponding to the front side of the distribution plate A condensation system for organic solvent recovery, in which a filter for removing fine foreign substances in steam or air supplied to the condenser, is inserted and filed by the applicant as a patent application No. 123077 in 2005 (Publication No .: 10-2006-11927, published). Date: February 06, 2006).

The condensation system for pre- filed organic solvent recovery as described above is installed with a condenser by selecting a distribution chamber of the shutter method to supply steam or air through the condenser or direct discharge to the atmosphere depending on whether organic solvent is included or not. It is possible to extend the service life of the filter and its replacement cycle to the maximum, and to control the discharge of the internal air and the inflow of external air by damper method according to the internal pressure of the sealed casing to achieve stable operation of the system. A distribution plate for dispersing the flow of steam or air at the front side of the condenser is installed with a filter to maximize the area where the vapor or air containing the organic solvent contacts the surface of the condenser, and at the same time, the compressor, the radiator and the condenser Refrigeration cycle consisting of a filter and a filter and a dispersion plate are integrated in one casing That can be easily installed in the air clothes dryer was to be compact and provide a miniaturized device.

However, since the pre- filed condensation system for organic solvent recovery removes high temperature steam from the clothes dryer or dust or foreign matter contained in the air by using a filter installed after the distribution chamber, the inflow space consisting of the distribution chamber and the shutter is included. There was a problem of being easily polluted by the dust or foreign matter, which not only exposed a problem which is somewhat unsuitable for the clean use of the system, but also hot steam or air without organic solvents into the air without any separate filtering. Since it is directly discharged, it is also an unfavorable problem in terms of preventing air pollution by dust and foreign matter.

In particular, the pre- filed condensation system for recovering organic solvents was able to condensate and recover organic solvents contained in air or hot steam supplied from a clothes dryer by using a condenser installed inside the closed casing. There was a problem that can not supply the high-temperature drying air required for drying of the clothes, and therefore, a separate electric heater or hot water heater must be installed in the clothes dryer to increase the cost of the clothes dryer equipment. Not only that, but it also exposes undesirable problems in terms of efficient recycling of energy.

In addition, in order to quickly dry laundry, the temperature of the drying air applied to the clothes dryer should generally be about 60 to 80 ° C. In this case, it is used to dry the laundry and then flows into the closed casing to come into contact with the condenser. The temperature of high temperature steam or air (containing organic solvent) is about 60 ℃ or more. If the inlet side temperature of the condenser is increased due to the characteristics of the refrigeration cycle, the load applied to the compressor is applied. There was a problem in that the drying time of the laundry by the clothes dryer is delayed because the temperature of the air cannot be increased above 50 ° C.

The first technical task is to contribute to the clean use and prevention of environmental pollution, and to further improve the convenience of cleaning and maintaining the condensation system.

In addition, the present invention is to dualize the radiator connected to the compressor and the condenser to the main radiator and the auxiliary radiator to reheat the air dried in the system by the main radiator, so that the electric heat or hot water heating method It is possible to supply the drying air of the laundry needed for the clothes dryer using only the circulation method of the refrigerant, thereby contributing to the efficient recycling of energy and the cost savings according to the equipment of the clothes dryer. It is a second technical problem to prevent excessive heat dissipation by a radiator located outside to contribute to the creation of a comfortable indoor environment.

In addition, the present invention by providing a guide vane close to the sensor in accordance with the air pressure of the exhaust air on the passage of the air discharged to the outside of the system to automatically turn on (ON) / off (OFF) operation of the system by The internal pressure of the airtight casing can be adjusted according to the situation by using the check damper which can control the opening and closing amount of the airtight casing which makes up the system. It is a third technical task to ensure that the safety of the use of the system can be ensured by blocking the risks that may occur if the degradation is much lower or far exceeding the reference value.

In particular, the present invention can be installed in a heat exchanger adjacent to the condenser to perform a heat exchange with the hot steam introduced into the system or the air discharged from the primary air discharged from the main heat radiator or the air cooled and dried in the condenser. In this way, the temperature of steam or air in contact with the surface of the condenser is relatively lowered, and the temperature of the drying air discharged to the outside of the system can be relatively increased, thereby minimizing the load of the compressor to minimize the load on the system.

Accordingly, the main radiator 28 and the condenser 5 include a control pipe for connecting the compressor 2, the main radiator 28, and the condenser 5 and the sub radiator 3. Means such as electric wires (not shown) for connecting with (6) are to penetrate the rear wall of the airtight casing 10, as described above, the portion where the refrigerant pipes or wires, etc. penetrate the rear wall of the airtight casing 10 It is preferable to seal the steam casing or the air flowing through the inside of the hermetic casing 10 so as not to leak to the outside, and the compressor 2, the auxiliary radiator 3, and the control panel 6 are supported as necessary. ) Can be used by installing a cover that covers from the outside.

In addition, in the drawing, the inlet pipe 11 is connected to the front wall of the sealed casing 10 at the upper right side thereof, and the first discharge pipe 12 is connected to the bottom of the central side, and the closed casing 10 is shown in the drawing. On the left side wall of the pressure adjusting pipe 13 having a damper 31 and the second discharge pipe 14 is installed up and down, the bottom of the closed casing 10 is condensed and recovered from the condenser 5 A recovery tank 7 for storing the solvent is provided, and the discharge pipe 8 of the organic solvent is connected to the front end of the recovery tank 7.

In addition, in the drawing, the right side wall of the closed casing 10 is provided with an opening / closing door 9 having a rotary handle 9a and a shutter handle 22 for operating the shutter 21 connected up and down. The opening / closing door 9 serves to cover the opening 10a formed on the side wall of the airtight casing 10 so that airtight holding is possible, and the door 9 is located inside the opening / closing door 9. There is an airtight holding means such as a packing hose or rubber ring (not shown) that is elastically in close contact with the outer circumferential surface of the opening 10a upon closing.

As described above, the opening and closing door 9 in which the airtight holding means such as the packing hose or the rubber ring is intermittently pressed to the outer surface of the airtight casing 10 may be completely sealed to the opening 10a of the airtight casing 10. Means for locking the opening / closing door 9 so that the tip of the rotary handle 9a of the opening / closing door 9 is firmly locked to the inside thereof on the side wall of the airtight casing 10. As the locking piece 9b is installed, the means for locking the opening / closing door 9 can be applied to various types of locking fixing means in addition to those shown in the drawings.

In addition, an inner space of the closed casing 10 corresponding to the front side of the condenser 5 is partitioned into an inlet space 15 communicating with the inlet pipe 11 by a diaphragm 15a, The inner space of the corresponding closed casing 10 is formed into a discharge space 30 in communication with the pressure adjusting tube 13 and the second discharge pipe 14, the space corresponding to the lower side of the inlet space (15) The first induction space 24 communicated to the condenser 5 side and the second induction space 25 communicated to the first discharge pipe 12 side by the silver “Y” shaped distribution chamber 20 are independent spaces. Divided into

A bag filter 16 connected to the inlet pipe 11 is inserted into the inlet space 15, and a flow hole 17a of steam or air is formed in the lower part of the bag filter 16. A support plate 17 for supporting the furnace bag filter 16 is installed to be located directly above the distribution chamber 20 together with the plate-shaped filter 18, and the bag filter 16 and the plate-shaped filter 18 are installed. The cartridge is detachably mounted along the inner frame 19 of the hermetic casing 10 by the opening / closing door 9 which covers the opening 10a of the hermetic casing 10 so as to maintain hermeticity. Insertion is possible.

Since the bag filter 16 is difficult to maintain a fixed shape due to its material property, a metal serving as an introduction tube on the head of the bag filter 16 can be easily attached and detached from the bag filter 16. By connecting the filter head 16a made of plastic or plastic, the inner flange fixed to the inner side surface of the front wall of the airtight casing 10 corresponding to immediately after the inflow pipe 11 by the front flange portion of the filter head 16a ( It is desirable to allow easy insertion or removal along 19).

Alternatively, the rear end of the inlet pipe 11 may pass through the front wall of the sealed casing 10 by a predetermined length, and then the bag filter 16 may be directly connected to the rear end of the inlet pipe 11. In addition, the plate-shaped filter 18 positioned below the bag filter 16 may include various kinds of filters including a fiber filter such as a nonwoven fabric, and the filter 18 itself has a constant supporting strength. If the support plate 17 is not required to be installed separately, the filter (between the inner wall of the front wall of the hermetic casing 10 and the diaphragm 15a so as to easily insert or detach the plate-shaped filter 18) A pair of inner frames 19 serving as guides of 18 are fixedly installed to face each other.

In addition, the distribution chamber 20 installed at the lower portion of the inflow space 15 is introduced into the sealed casing 10 through the inflow pipe 11 as shown in FIGS. 3 and 4 more clearly. Serves to selectively supply steam or air to the first induction space 24 on the condenser 5 side or the second induction space 25 on the first discharge pipe 12 side according to the presence or absence of the organic solvent. To this end, flow passages 20a and 20b serving as inlets of the induction spaces 24 and 25 are cut in a square shape at the front and rear sides of the distribution chamber 20 having a triangular hopper shape. .

As described above, in the upper center portion of the distribution chamber 20 to allow the user to selectively operate the flow path of steam or air through the first and second induction spaces 24 and 25 according to the presence or absence of the organic solvent. Shutter 21 is installed, and the shutter 21 penetrates the wall of the airtight casing 10 from the shutter handle 22 provided outside the airtight casing 10 so as to maintain airtightness. As the lower end of the body is connected to the rotating shaft 23 which extends, the shutter 21 rotates toward each of the flow passages 20a and 20b of the distribution chamber 20 according to the rotation operation of the shutter knob 22. It is made so as to be in close contact with the body of the shutter 21 to prevent the noise caused by the operation of the shutter 21 and at the same time to more securely seal each flow passage (20a, 20b) of the distribution chamber 20. It is preferable to attach elastic bodies such as rubber plates along the front and rear surfaces.

In addition, a dispersion hole is formed between the flow passage 26 formed by cutting the diaphragm 15a and the condenser 5 as a counterpart of the first induction space 24 over the entire body of the plate shape. A distribution plate 27 having a through hole 27a is installed, and the distribution plate 27 widely disperses a main stream of steam or air introduced into the condenser 5 through the first induction space 24, The vapor or air containing the organic solvent is in contact with the surface of the condenser (5) to ensure a wider area for condensation.

In addition, the condenser 5 for condensing and recovering the organic solvent contained in the steam or air introduced into the closed casing 10 is a pipe arranged in a plurality of rows as in the case of a conventional heat exchanger. It is common to have a refrigerant evaporation structure of a shape, that is, a condensation structure of an organic solvent, but if it is possible to condense and recover the organic solvent due to evaporation of the refrigerant, it may be relatively similar to a plate type and a pin tube type. Various other types of heat exchange structures can be applied which can perform a good condensation function.

As shown in FIG. 4 more clearly, the remaining inner space of the closed casing 10 formed in the shape of a rough counter-reverse (“┏”) shape except for the inflow space 15 is connected to the condenser 5. Through the second discharge pipe 14 to form the discharge space 30 to be discharged to the outside of the sealed casing 10 through the second discharge pipe 14, the closed casing 10 through the discharge space (30) The main radiator 28 is installed at the rear of the condenser 5 at regular intervals so as to re-heat the air discharged to the outside of the condenser 5 so as to supply the drying air required for the clothes dryer.

The main radiator 28 is a high-temperature, high-pressure refrigerant discharged from the compressor 2 is primarily introduced to perform the heat radiation (condensation of the refrigerant) function of the refrigerant, the air cooled in the condenser 5 is the main radiator Heated to a constant temperature in the course of passing through (28), and then is discharged to the outside of the closed casing 10 via the second discharge pipe 14 it is possible to supply the drying air required for the clothes dryer.

Like the condenser 5, the main radiator 28 also has a pipe-shaped refrigerant condensation structure, that is, a heating structure of exhaust air. However, if the exhaust air can be heated by condensation of the refrigerant, plate type, Different types of heat exchange structures that can perform relatively good heat dissipation, such as fin and tube types, can be applied.

As described above, the organic solvent recovery condensation system according to the present invention passes the vapor or air containing the organic solvent through the condenser 5 to condense and recover the organic solvent, and then the main radiator 28 adjacent to the condenser 5. Since it is a system for reheating the exhaust air by using a), as shown in FIG. 3 to prevent the condensed organic solvent from evaporating again by the heat generated from the main radiator (28) of the condenser (5) It is preferable that the lower end penetrates the bottom of the hermetic casing 10 and is inserted into the recovery tank 7, and the heat generated from the main radiator 28 is formed at the bottom of the hermetic casing 10. In order not to be transferred to the recovery tank 7 through the bottom surface, a separate heat insulating material is applied to the bottom surface, or the bottom plate of the airtight casing 10 is formed of heat insulation material, or the bottom plate of the airtight casing 10. It is to form a double bottom is preferred.

In other words, the organic solvent flowing down the bottom of the closed casing 10 along the surface of the condenser 5, such as a pre- filed condensation system for recovering the organic solvent, is passed through the drain port 10b formed at the bottom of the closed casing 10. Although it may be allowed to flow into the recovery tank (7), in this case, some of the organic solvent accumulated in the bottom surface of the airtight casing (10) without draining through the drain (10b) to the heat generated from the main radiator (28) Because of the possibility of evaporation again, the lower end of the condenser (5) is charged into the recovery tank (7) and the organic solvent flowing down along the surface of the condenser (5) through a heat insulating bottom plate recovery tank ( 7) is to be introduced directly into the interior, and directly connected to the drain pipe or drain hose not shown in the drain port (10b) formed in the bottom of the closed casing 10 without installing the recovery tank (7) It may be used.

A blocking wall 38 serving as a partition is installed to be guided to the side of 37, and front and rear surfaces of the heat exchanger 37 block drying air from passing through the heat exchanger 37 without passing through the heat exchanger 37. It is installed in close contact with the distribution plate 27 and the condenser 5 so as to be able to.

The heat exchanger 37 used in the condensation system 1 according to the second embodiment of the present invention is heat-transfer having a cross-sectional shape as shown in Figs. 8A and 8B, respectively. Pipes 371 are installed in a stacked manner at regular intervals, so that the outer space of each of the heat transfer pipes 371 flows into the sealed casing 10 and is supplied to the condenser 5 side by a flow passage of hot steam or air ( 373, and the inner space of each heat pipe 371 forms the flow passage 374 of the drying air discharged to the outside of the sealed casing 10 through the condenser 5 and the main radiator 28. do.

In addition, interposed between both ends of each heat transfer pipe 371 supports each heat transfer pipe 371 in a state spaced apart by a predetermined interval to form a flow passage 373 outside the heat transfer pipe 371. At the same time, the drying air supplied to the inner flow passage 374 of the heat transfer pipe 371 via the condenser 5 and the main radiator 28 is prevented from being introduced into the outer flow passage 373. The spacer 375 may be formed by attaching or filling a packing material such as rubber or synthetic resin between the heat transfer pipes 371, and inserting a corrugated metal plate between the heat transfer pipes 371 between the heat transfer pipes 371. ) May be formed integrally by welding.

9A and 9B show another form of the heat exchanger 37 used in the second embodiment of the present invention, in which the heat transfer pipe 372 having a circular cross section is fixed. It is installed in a stacked manner at intervals, so that the outer space of each heat transfer pipe 372 flows into the sealed casing 10 to form a high-temperature steam or air flow path 373 supplied to the condenser 5 side, The inner space of each heat transfer pipe 372 forms a flow passage 374 of the drying air discharged to the outside of the sealed casing 10 through the condenser 5 and the main radiator 28.

Further, by installing both ends of each heat pipe 372 so as to be supported through the side plate 376, the flow path 373 can be formed on the outer side of each heat pipe 372, and at the same time, the condenser 5) and the drying air supplied to the inner flow passage 374 of the heat transfer pipe 372 through the main radiator 28 is blocked to flow into the outer flow passage 373, each heat transfer pipe 372 It is preferable to seal the part through the side plate 376 to the extent that airtightness is possible.

The heat exchanger 37 described above lists only representative structures that can be applied to the condensation system 1 according to the present invention, and the shape or arrangement of the heat transfer pipes 371 and 372 or the heat transfer pipes 371 and 372. ) Can be arbitrarily adjusted, and independent flow passages 373 and 374 are formed on the inner and outer sides of the heat transfer pipes 371 and 372 to flow into the closed casing 10. If the high temperature steam is capable of performing heat exchange with the drying air discharged to the outside of the airtight casing 10 through the air and the condenser 5 and the main radiator 28, various structures other than those shown in the drawings Note that the heat exchanger can be applied.

In addition, it is shown in Figure 8 that the heat exchange efficiency of the heat exchanger 37 shown in Figures 8 and 9 is more excellent, the reason is the inner and outer flow passages of the heat transfer pipe (371) As the 373 and 374 have a corrugated cross section, the flow of fluid (air and / or vapor) through the flow passages 373 and 374 is more complex than in the case of a simple circular cross section. In order to guide the flow of the fluid through the flow passages (373, 374) more complex, and to maximize the heat transfer area in each of the heat transfer pipes (371, 372), Projections, wrinkles and the like of various shapes may be formed on the outer surface.

FIG. 10 shows a third embodiment of the present invention, in which a heat exchanger 37 is installed between the distribution plate 27 and the condenser 5, and is the same as the second embodiment. The only difference is that a pair of heat exchangers 37 having the same structure are arranged in close contact in parallel between the dispersion plate 27 and the condenser 5 so that the condenser 5 and the main radiator 28 are connected. Through the flow passage of the drying air discharged to the outside of the sealed casing 10 to form a zigzag shape along each heat exchanger 37, further improves the heating function of the drying air by the heat exchanger 37. It was made to be.

To this end, in the third embodiment of the present invention, as in the first embodiment, the condenser 5 and the main radiator 28 are in close contact with the right wall of the hermetic casing 10 in the drawing, so as to roughly show the counterweight. In the state in which the discharge space 30 of the shape is formed, on the left side of each heat exchanger 37, a blocking wall 38 for adjusting the flow path is provided between the close contact portion of the heat exchanger 37 and the inner surface of the hermetic casing 10. It is fixedly installed, and the right end of each heat exchanger 37 is installed to be spaced apart from the side wall of the airtight casing 10 so as to secure a turning passage of the drying air.

11 shows a fourth embodiment of the present invention, in which the arrangement of the condenser 5, the main radiator 28 and the heat exchanger 37 is changed, and the high temperature steam introduced into the sealed casing 10 By allowing the air to perform heat exchange with the air dried through the condenser 5, the heat exchange efficiency generated in the heat exchanger 37 is further increased. It is made in the same way as the configuration.

As shown in FIG. 11, the condensation system 1 according to the fourth embodiment of the present invention has a flow passage formed by cutting the diaphragm 15a in the outlet of the first induction space 24 (FIG. 3). (26)} In the rear side, a partition 39 is firstly installed to secure a smooth flow space of steam or air, and then the heat exchanger 37 is perpendicular to the rear side of the partition 39. It is installed in close contact with the flow path (39a) formed by cutting the partition 39 is made to serve as an inlet of the heat exchanger (37).

However, the heat exchanger 37 may be directly in contact with the diaphragm 15a without installing the partition 39 as described above. In this case, the flow passage formed by cutting the diaphragm 15a in FIG. 26 serves as an inlet of the heat exchanger 37, and the flow of steam or air discharged through the first induction space 24 passes through the entire heat transfer pipes 371 and 372 of the heat exchanger 37. It is desirable to take the former method as much as possible so that it can be derived more effectively.

In addition, in the drawing, the condenser 5 and the main radiator 28 are connected to the heat exchanger 37 in parallel with the heat exchanger 37 at the right side and the left side of the heat exchanger 37, and the condenser 5 is installed. And the main radiator 28 and the heat exchanger 37 are spaced apart from the rear wall of the hermetic casing 10 at regular intervals, the left rear end of the heat exchanger 37 and the rear wall of the hermetic casing 10. Between the side surfaces, a blocking wall 38 for adjusting the flow path is provided.

Therefore, the hot steam or air introduced into the sealed casing 10 passes through the heat exchanger 37 to turn to the condenser 5 side, and then the hot steam or air passes through the condenser 5. The organic solvent contained therein is condensed and recovered, and the air dried through the condenser 5 is heated in the process of passing through the heat exchanger 37 and the main radiator 28, and then the By discharging to the outside, the hot steam or air introduced into the closed casing 10 is made to perform a heat exchange with the air dried in the condenser (5).

Further, the heat exchanger 37 used in the fourth embodiment of the present invention also has the same structure as the heat exchanger 37 shown in FIGS. 8 and 9, and the heat exchanger according to the second to third embodiments The difference from (37) is that the high temperature steam flowing into the sealed casing 10 through the first induction space 24 through the flow passage 374 corresponding to each of the heat transfer pipes 371 and 372. The flow path of the air is different from the flow path configuration of the air flow path 373 corresponding to the outside of each of the heat transfer pipes 371 and 372 to be the air flow path of the air cooled by the condenser 5.

FIG. 12 shows a fifth embodiment of the present invention, in which a heat exchanger 37 is installed at an outlet side of a first induction space 24, and the condenser 5 and a main radiator 28 are positioned at both sides thereof. It is the same as the fourth embodiment, except that the only difference is that a pair of heat exchangers 37 having the same structure between the condenser 5 and the main radiator 28 are closely installed in parallel, and 1The flow path of the hot steam or air flowing into the sealed casing 10 from the induction space 24 forms a zigzag shape along each heat exchanger 37, thereby drying air by the heat exchanger 37. It is to further improve the heating function and heat exchange performance of.

To this end, in the fifth embodiment of the present invention, one end of the heat exchanger 37 of the pair of heat exchangers 37 exits the first induction space 24, that is, the flow passage of the partition 39. (39a), the other end of the heat exchanger (37) is spaced apart from the partition (39) at regular intervals, the rear end of each heat exchanger (37) is a pair of flow path adjustment blocking wall (38) Hot air or air supplied to the condenser 5 through the first induction space 24 by being spaced apart from the rear inner surface of the closed casing 10 together with the condenser 5 and the main radiator 28 by a predetermined distance. The flow passages of the to form a zigzag shape along each heat exchanger (37).

In the fourth and fifth embodiments, a separate dispersion plate 27 is not installed between the outlet side of the first induction space 24 and the heat exchanger 37. The reason is that the first induction space ( Since the flow path of steam or air supplied to the condenser 5 via 24 is interfered by the space formed by the partition 39 and the heat transfer pipes 371 and 372 of the heat exchanger 37, This is because only the partition 39 and the heat exchanger 37 can disperse the main stream of steam or air to some extent before contacting the condenser 5.

In other words, the main flow of steam or air discharged through the first induction space 24 is not only primarily dispersed in the space formed by the partition 39 but also shown in FIGS. 8 and 9. As the arrangement of the heat transfer pipes 371 and 372 by the spacer 375 or the side plate 376, the inlet-side structure of the heat exchanger 37 can serve as another distribution plate. Therefore, the said dispersion plate 27 can also be installed and used in the space created by the partition 39.

In each of the embodiments of the present invention described above, the blocking wall 38 is used to adjust the flow path of steam or air, but the portion of the empty space without affecting the flow path of steam or air is sealed casing. In the case of the inside of the 10, the wall itself of the hermetic casing 10 is directly in contact with the condenser 5, the main radiator 28 or the heat exchanger 37 so that the space does not occur, the hermetic casing ( It may be possible to reduce the overall volume occupied by 10).

In addition, in the third and fifth embodiments of the present invention described above, a pair of heat exchangers 37 are used to form a zigzag flow path, but the installation volume of the sealed casing 10 is greatly limited. If not received, by arranging three or more heat exchangers 37 in parallel, securing a longer length of the zigzag flow path by the heat exchangers 37, thereby improving the heating function and heat exchange performance of the drying air. It's important to note that it can be improved further.

Hereinafter, the working relationship of the present invention having the above configuration will be described in detail with reference to the accompanying drawings.

First, while connecting the clothes dryer used in the laundry and the condensation system 1 of the present invention, the inlet pipe 11 of the closed casing 10 constituting the condensation system 1 is provided with a blowing fan from the clothes dryer. It is connected to the supply duct of the steam or air extending in a state, and the first discharge pipe 12 of the hermetic casing 10 is connected to the discharge duct extending to the outdoor side, the second discharge pipe 14 is a clothes dryer By connecting to a supply duct for supplying air for drying the furnace, the clothes dryer and the condensation system 1 according to the present invention to form a closed passage.

In the state in which the condensation system 1 according to the present invention is installed together with the clothes dryer as described above, when performing the drying operation of the water-laundered clothes in which the organic solvent is not used by the clothes dryer, the shutter handle 22 is used. Rotate the shutter 21 installed in the distribution chamber 20 of the inflow space 15 toward the rear inflow passage 20a of the distribution chamber 20 so that the inflow passage 20a is connected to the shutter 21. To be closed.

In such a state, steam or air discharged from the clothes dryer in the state of not containing organic solvent is introduced into the bag filter 16 through the inlet pipe 11 of the hermetic casing 10, so that the vapor or air The contained dust or foreign matter is first filtered and then passed through the plate-shaped filter 18 through the flow hole 17a of the support plate 17 located on the lower side of the bag filter 16, thereby containing it in steam or air. After the collected dust or foreign matter is secondaryly filtered, it is discharged to the atmosphere through the first discharge pipe 12 through the front inflow passage 20b and the second induction space 25 of the distribution chamber 20.

On the other hand, when performing the drying operation of the laundry containing the organic solvent using a clothes dryer, the shutter 21 is installed in the distribution chamber 20 of the inlet space 15 using the shutter handle 22. Is rotated toward the front inlet passage 20b side of the distribution chamber 20 so that the inlet passage 20b is closed by the shutter 21, the hot steam or air generated during the drying of the laundry from the clothes dryer is seen. It is to be supplied to the condensation system 1 according to the invention.

In such a state, the vapor or air discharged from the clothes dryer in the state of containing the organic solvent is introduced into the bag filter 16 through the inlet pipe 11 of the hermetic casing 10, thereby containing in the steam or air. The dust or foreign matter is first filtered and then passed through the plate-shaped filter 18 through the flow hole 17a of the support plate 17 located on the lower side of the bag filter 16, thereby to be contained in the vapor or air. After the dust or foreign matter is secondaryly filtered, it is discharged to the condenser 5 through the rear inflow passage 20a and the first induction space 24 of the distribution chamber 20.

As described above, in the condensation system 1 according to the present invention, the distribution chamber of the shutter 21 type which selects the supply of high temperature steam or air through the condenser 5 or direct discharge to the atmosphere according to the presence or absence of organic solvent ( 20) By installing the bag filter 16 and the plate-shaped filter 18 on the upper side, condensation system (1) by minimizing dust or foreign matter attached to the surface of the distribution chamber 20 and the shutter 21 or directly discharged to the atmosphere Will contribute to the clean use and prevention of environmental pollution.

In addition, the bag filter 16 and the plate-shaped filter 18 are detachably cartridgeed along the inner frame 19 of the hermetic casing 10 by an opening / closing door 9 installed outside the hermetic casing 10. Since the insertion is possible, the cleaning or replacement of each filter 16, 18 can be performed very easily, thereby contributing even more to the clean use side of the condensation system 1.

Before or after the operation of the shutter 21 to allow the hot steam or air discharged from the clothes dryer in the state containing the organic solvent to the condenser 5 side through the first induction space 24 as described above. At the same time, a refrigeration cycle comprising an auxiliary radiator 3 having a compressor 2 and a heat radiating fan 4 and a main radiator 28 and a condenser 5 by operating a switch or the like not shown in the control panel 6. In this case, the condenser 5 is set to the ON state of the condensation system 1 capable of condensation recovery of the organic solvent, and the proximity switch 29 or the same function as described above is performed. When other types of sensors are installed, the condensation system 1 is automatically set to an ON state in accordance with the flow of steam or air flowing through the discharge space 30.

As described above, the condensation system 1 is set to an ON state so that steam or air introduced into the closed casing 10 from the clothes dryer is introduced into the inlet space 15, the distribution chamber 20, and the first induction space. In the process of flowing into the condenser 5 side via the 24, the main stream of steam or air is dispersed widely while simultaneously hitting the dispersion plate 27 provided at the front side of the condenser 5, and then the dispersion plate 27 is provided. By being evenly guided to the condenser 5 side through each of the dispersion holes 27a formed in the condenser 5, the vapor or air containing the organic solvent is brought into contact with the entire surface of the condenser 5 with a very large contact area. The condensation of organic solvents by 5) and the recovery rate thereof can be greatly improved.

The organic solvent condensed in contact with the surface of the condenser 5 as described above flows down the inside of the recovery tank 7 through the bottom of the heat-insulated closed casing 10 along the surface of the condenser 5, thereby recovering the tank. Stored in (7), the organic solvent thus stored is discharged to the discharge pipe (8) of the recovery tank (7) to be reused, and the air is cooled and dried with the organic solvent removed through the condenser (5) condenser (5) It is heated again while passing through the main heat radiator 28 immediately afterwards, and then re-supplied to the clothes dryer via the second discharge pipe 14 of the closed casing 10 so as to supply dry air for drying the laundry. do.

In other words, in the first embodiment of the present invention shown in Fig. 4, when the temperature of steam or air discharged from the clothes dryer is about 50 ° C, the temperature of the air that is cooled and dried by passing through the condenser 5 is about 15 ° C. And the air thus cooled and dried is reheated to dry air at about 60 ° C. through the main radiator 28, and then supplied to the clothes dryer through the second discharge pipe 14 of the hermetic casing 10. Even if a separate electric heater or hot water heater is not installed in the clothes dryer, it is possible to supply dry air for drying the laundry.

According to the first embodiment, the air dried by cooling in the condenser 5 may be reheated in the main radiator 28 to supply dry air required for the clothes dryer. In direct contact with (5), somewhat higher in terms of shortening the drying time of the laundry by raising the temperature of the hot steam or air flowing into the closed casing 10, that is, the drying temperature of the laundry by the clothes dryer. There is a lack.

In other words, when the drying temperature of the laundry is increased, the temperature on the inflow side of the condenser 5 becomes high, and a rather unreasonable load is applied to the compressor 2 due to the characteristics of the freezing cycle. In the example, even if the drying temperature of the laundry is increased by installing a heat exchanger 37 in front of the condenser 5 so as to compensate for this disadvantage, the inlet side temperature of the condenser 5 can be maintained at a stable level. have.

In the case of the second and third embodiments of the present invention, as shown in Figs. 7 and 10, respectively, when the temperature of steam or air discharged from the clothes dryer is about 60 ° C, the steam is supplied to the condenser 5 side. The temperature of the air can be lowered to about 50 ° C. in the heat exchanger 37. The air cooled by about 15 ° C. by the main radiator 28 is passed through the condenser 5. This is because after being reheated with dry air and passing through the heat exchanger 37, the inflow air at 60 ° C. and the discharge air at 45 ° C. exchange heat with each other inside the heat exchanger 37.

Therefore, the temperature of the drying air supplied to the clothes dryer through the second discharge pipe 14 of the hermetic casing 10 is formed to about 50 ℃, such a temperature difference of about 10 ℃ using a small heater such as cheap This is a level that can be quickly and simply increased, when considering the advantageous aspect that the drying temperature of the laundry by the clothes dryer can be increased while maintaining the inlet side temperature of the condenser 5 stably, the laundry can be dried more quickly. It doesn't matter.

In addition, as in the third embodiment of the present invention, when the drying air discharged to the second discharge pipe 14 of the hermetic casing 10 is zigzag-flowed through the pair of heat exchangers 37, Compared to the second embodiment, the inlet side temperature of the condenser 5 may be lowered by about 2 to 3 ° C, and the temperature of the drying air supplied to the clothes dryer through the second discharge pipe 14 is about 2 to 3 ° C. You can go higher.

According to the fourth and fifth embodiments of the present invention, taking in only the advantages of each of the embodiments described above, even if the temperature of steam or air discharged from the clothes dryer, that is, the drying temperature of the laundry is very high, the inflow of the condenser 5 The temperature at the side can be formed at a stable level, and the temperature of the drying air supplied to the clothes dryer through the second discharge pipe 14 is introduced into the condensation system 1 without using a separate electric heater or hot water heater. It can be made higher than the vapor or air temperature.

In other words, in the fourth and fifth embodiments of the present invention shown in FIGS. 11 and 12, the temperature of steam or air flowing into the heat exchanger 37 from the clothes dryer through the first induction space 24 is shown. When the temperature is about 70 ° C., the temperature of the steam or air flowing through the heat exchanger 37 toward the condenser 5 becomes about 40 ° C., which means that the air cooled by about 5 ° C. through the condenser 5 is dried. By directly passing through the heat exchanger 37, 70 ° C inlet air and air cooled to 5 ° C inside the heat exchanger 37 performs heat exchange with each other.

Therefore, even if the temperature of the steam or air flowing from the clothes dryer, that is, the drying temperature applied to the clothes dryer is about 70 ° C., the inlet side temperature of the condenser 5 can be maintained at a stable level of about 40 ° C. The air, which has been cooled and dried to about 5 ° C. through the condenser 5, is primarily heated to about 35 ° C. while passing through the heat exchanger 37, and then heated to about 80 ° C. by the main radiator 28. Heated.

As described above, the main heat radiator 28 may be heated to a high temperature of about 80 ° C. by the main radiator 28 while the drying air primarily heated to about 35 ° C. while passing through the heat exchanger 37 as described above. Installed immediately before the two discharge pipes 14, the drying air is discharged at substantially the same time as the heating of the drying air, and thus the inside of the closed casing 10 even if the capacity of the main radiator 28 is large. This is because the condensation system 1 can be stably operated without causing an increase in temperature or internal pressure.

In addition, when the capacity of the main radiator 28 is larger than the capacity of the condenser 5, the compressor 2 may have a capacity of the refrigeration cycle that dissipates the amount of heat energy absorbed by the condenser 5 from the main radiator 28. In the process of converting the electrical energy into kinetic energy and compressing and transporting the refrigerant, heat energy generated as much as electricity is consumed is transferred together with the kinetic energy in a state of being included in the refrigerant. ), More heat energy is emitted, and thus, the temperature of the drying air discharged through the condensation system 1 is higher than the temperature of steam or air flowing into the condensation system 1.

As described above, since the temperature of the drying air discharged through the second discharge pipe 14 of the hermetic casing 10 becomes about 80 ° C., the heat loss through the pipe and the heat loss of the clothes dryer itself are separate. The drying temperature of the clothes dryer can be maintained at a level of 70 ° C without an electric heater or a hot water heater, and thus the temperature of steam or air flowing into the condenser 5 while shortening the drying time of the laundry by the clothes dryer. In addition, it is possible to maximize the recovery rate of the organic solvent by further lowering the energy consumption, and also maximize the recovery rate and recycling rate of the energy to operate the condensation system 1 with high efficiency, and to minimize condensation by minimizing the load on the compressor 2. It is possible to ensure the safe operation of the system (1).

In addition, as in the fifth embodiment of the present invention, a pair of heat exchangers 37 are installed between the condenser 5 and the main radiator 28 so that the air that is cooled and dried through the condenser 5 is heat exchanged. When the zigzag flow along the group 37 is performed to exchange heat with hot steam or air introduced into the closed casing 10, the temperature of the inlet side of the condenser 5 is increased to 2 ~. It may be lowered by about 3 ℃, the temperature of the drying air supplied to the clothes dryer through the second discharge pipe 14 can be increased by about 2 ~ 3 ℃.

Changes in the internal pressure of the closed casing 10 that may occur during the operation of the condensation system 1 according to each embodiment of the present invention as described above can be summarized in each of the following situations, the first organic solvent When hot steam or air discharged from the clothes dryer when not in use is directly discharged into the atmosphere through the second induction space 25 and the first discharge pipe 12 of the airtight casing 10, the inside of the clothes dryer Since the drying air should be continuously supplied, the internal pressure of the airtight casing 10 is greatly reduced in the process of supplying the internal air of the airtight casing 10 to the clothes dryer side through the second discharge pipe 14. .

In addition, even when drying the laundry containing the organic solvent, the internal pressure of the closed casing 10 is slightly decreased due to the condensation of the organic solvent by the condenser 5, but the condensation system 1 operates normally. In this case, since the pressure drop is compensated for by the expansion action of the air by the main radiator 28, the internal pressure of the closed casing 10 is maintained at a level of atmospheric pressure.

However, in the use of the condensation system 1 according to the embodiment of the present invention, the compressor 2 is overloaded, and condensation of the organic solvent by the condenser 5 is not performed properly, or the closed casing 10 is performed. When the drying air discharged to the clothes dryer by turning the inner space of the gas is not properly discharged due to various reasons such as clogging of the pipe or flow resistance, the internal pressure of the sealed casing 10 increases.

As described above, the internal pressure change of the airtight casing 10 that may occur during the operation of the condensation system 1 is a damper of the pressure regulating pipe 13 installed together with the second discharge pipe 14 as described above. 31) by opening a predetermined ratio, so that when the internal pressure of the hermetic casing 10 decreases, the outside air flows in, and when the internal pressure of the hermetic casing 10 rises, the increased internal pressure can be discharged to the outside. By doing so, the internal pressure of the airtight casing 10 can be kept constant at the reference value (atmospheric pressure level), thereby condensing while excluding the danger that the highly volatile organic solvent may explode by high pressure and temperature. It is possible to ensure the safe operation of the system (1).

In addition, when the damper 31 provided in the pressure regulating tube 13 is installed and used as the variable flow checker damper 36 shown in FIG. 6, the bracket 363 provided in the outer side of the pressure regulating tube 13 is used. And the adjustment knob 365 allow the user to accurately grasp the opening degree of the pressure adjusting pipe 13 by the flap 361 to operate the damper 36, thereby closing the casing 10 by the damper 36. In addition to the more accurate adjustment of the internal pressure of the damper (31), it is possible to perform the automatic discharge of drying air and increase the internal pressure of the sealed casing (10) when the internal pressure of the sealed casing (10) increases. Effective flow control such as rapid inflow (opening rate of the pressure regulator tube by the flap + free rotation of the flap in the open direction) is enabled.

Finally, in the case where the condensation system 1 according to the present invention is installed and used together with a clothes dryer, various dusts may be formed on the surface of the auxiliary radiator 3 corresponding to the suction side of the indoor air by the heat radiating fan 4. When the purification filter 34 for removal and the deodorization filter 35 for adsorption and removal of various odors are installed, various dusts and odors contained in the indoor air are circulated in the circulation of the indoor air by the heat radiating fan 4. Purification and removal in the course of passing through the filter (34) (35) of the not only can keep the indoor air in a comfortable state at all times, but also the dual radiator (3) by dualizing the radiator (3) (28) Since only the bay is installed outside, it is possible to minimize the heat emitted from the radiator (3) to maintain the indoor environment comfortably even without discharging the heat radiated by a separate duct to the outside.

As described above, the organic solvent recovery condensation system according to the present invention has a bag on the upper side of the distribution chamber of the shutter method that selects the supply of high temperature steam or air through the condenser or direct discharge to the atmosphere depending on the presence or absence of the organic solvent. By installing the filter and the plate-shaped filter in a cartridge type, it is possible to minimize the foreign substances attached to the surface of the distribution chamber and the shutter or directly discharged into the air, thereby contributing to the clean use of the system and preventing the environmental pollution. At the same time, the bag filter and the plate-shaped filter are inserted and detachably inserted along the inner frame of the sealed casing by an opening / closing door installed outside the sealed casing. It is very easy to carry out, which makes the condensation system clean. There is an effect that can further improve the usability of the cleaning and maintenance of the condensing system.

In addition, the present invention is to dualize the radiator connected to the compressor and the condenser to the main radiator and the auxiliary radiator to reheat the air dried in the system by the main radiator, so that the electric heat or hot water heating method It is effective to supply the dry air of the laundry needed for the clothes dryer only by the circulation method of the coolant without applying this, which contributes to the efficient recycling of energy and the cost reduction according to the equipment of the clothes dryer. By preventing excessive heat dissipation by the radiator located outside the sealed casing, there is an effect that can create a comfortable indoor environment even without discharging the heat radiated to the outside using a separate duct.

In addition, the present invention by providing a guide vane close to the sensor in accordance with the air pressure of the exhaust air on the passage of the air discharged to the outside of the system to automatically turn on (ON) / off (OFF) operation of the system by In addition, the system has the effect of enabling efficient and efficient operation of the system, and by using a check damper that can control the opening and closing amount of the system, it can be properly adjusted according to the situation. By blocking the risks that may occur when the internal pressure is far lower than the reference value or far above the reference value, there is an effect that can ensure the safety of the use of the system.

In particular, the present invention can be installed in a heat exchanger adjacent to the condenser to perform a heat exchange with the hot steam introduced into the system or the air discharged from the primary air discharged from the main heat radiator or the air cooled and dried in the condenser. As a result, the temperature of the steam or air in contact with the surface of the condenser is relatively lowered, and the temperature of the drying air discharged to the outside of the system is relatively increased, thereby increasing the load on the compressor. To minimize the need for more stable and smooth operation of the system while maximizing the recovery rate of organic solvents and recycling of energy and enabling the system to operate more efficiently. Also, the effect is to make it as short as possible. All.

Finally, in the case where the condensation system according to the present invention is installed and used together with a clothes dryer, a purifying filter and various odors for the removal of various dusts on the auxiliary radiator surface corresponding to the suction side of the indoor air by the heat radiating fan are used. When the deodorization filter is installed to remove the adsorption, various dusts and odors contained in the indoor air are clarified and removed in the process of circulating the indoor air by the heat dissipation fan. It is effective to maintain.
