The present invention recovers solvent and moisture by condensing high temperature and humid solvent-containing air, ie, steam, generated when drying laundry washed with a solvent, and preheating air whose temperature has been reduced by heat exchange of the cooling device. In the solvent recovery machine, which is used to dry laundry by returning it to heat, the preheated air is heated to a level that is compatible with the interior atmosphere of the drying room and used as heat energy for laundry drying. It relates to a laundry dryer-mounted solvent recovery device that can be mounted.

In a general laundry, laundry washed with organic solvents is dried in a dryer. The laundry dryer supplies high-temperature steam to the drying chamber to dry the solvent laundry. As the laundry is dried, oil vapor containing the solvent is generated. When the vapor is released into the atmosphere, the air is polluted, pedestrians in front of the laundries suffer from breathing difficulties due to odors, and solvents discharged mixed with condensate contaminate river water.

In consideration of this point, the proposed organic solvent recovery machine for a laundry dryer, that is, a solvent recovery machine, is proposed. Typical examples are Utility Model Registration Nos. 393864 and 414531. The former prior art is the first condensation of the vapor from the drying chamber with a two-piece cooling device, and then passed through a sand-shaped flexible tube of the double tube cooling section to recover the solvent and condensate by secondary condensation, the temperature due to condensation Is to supply the lowered air directly to the drying chamber without preheating or heating, and the latter prior art is to install a cooling device and a preheater in series in a straight oil vapor discharge passage to preheat the air after condensation to be supplied into the dryer. .

In the former case, the temperature inside the drying chamber is lowered due to the low temperature air introduced into the drying chamber after the solvent and the moisture are recovered, which slows down the drying of the laundry, and the heat energy ratio required for forming the interior atmosphere of the drying chamber is uneconomical. In addition, as the solvent recovery machine is installed next to the drying room, it is inevitable that the width of the existing laundry dryer is inevitable, and thus, the supplier is burdened with the production cost, and from the customer's point of view, the working space in the workplace becomes as large as the occupied area of the dryer due to the solvent recovery machine. It's a problem.

In the latter case, the condensation efficiency of the cooling device is low because the cooling device and the preheating device are not isolated and are affected by the preheating device. In addition, simply preheating the air after condensation is difficult to conform to the internal atmosphere of the drying chamber having a high temperature, and the problem is that the heat energy cost for drying is added according to the temperature difference between the preheated air and the internal temperature of the drying chamber. In addition, the problem is that the means for inducing the preheated air to enter the drying chamber is a long duct, so that the heat loss is likely to occur on the way to the drying chamber. The conventional laundry dryer is virtually impossible to implement because the space provided in the lower part of the drying chamber is provided with a filtration device for steam discharge and a forced discharge blower, and the remaining space is too narrow to hold a solvent recoverer. To overcome this, the height of the laundry dryer should be designed as high as the space occupied by the solvent recoverer. Doing so will increase the appearance and make it difficult to install in a narrow, low-ceiling cleaner.

It is a further problem that any type of solvent recoverer is installed inside a laundry dryer, making it difficult to apply to existing washing machines.

In this regard, the future solvent dryer for laundry dryer overcomes the technical limitations of only preheating the air after condensation and reduces the heat energy for drying by supplying it by heating it directly to the high temperature atmosphere inside the drying chamber. There is a need for a solvent recovery machine that can be easily installed and operated without changing the appearance of existing laundry dryers.

Therefore, the purpose of the present invention is that the condensation of the vapor is not affected by the preheating of the gas after condensation, and it is possible to improve the drying efficiency and reduce the heat energy cost by heating and supplying the preheated air after condensing to the interior atmosphere of the dryer. In addition, the present invention provides a laundry dryer-mounted solvent recoverer which can be easily installed and operated without changing the appearance of the existing laundry dryer.

The task is to divide the interior of the housing into which the cooling device and the preheater are built into a condensation chamber and a preheating chamber with a plurality of partitions, and additionally form a heating chamber in the rear of the preheating chamber, and each chamber is provided with oil vapor, condensed air, and preheated air. Is connected to the passage so that the condensation efficiency is lowered due to the heat released when preheating the air, and the preheated air is heated to a level comparable to the internal atmosphere of the drying room to supplement the drying heat energy. It can be achieved with a laundry dryer-mounted solvent recovery system that can be installed and operated simply by mounting it on top of the existing laundry dryer without changing its appearance.

In FIG. 1, the housing 10 for solvent recovery is horizontal. That is, the inside is divided into the horizontal condensation chamber 13 and the horizontal preheating chamber 14 by the partition 11a, and divided into the vertical heating chamber 15 which communicates with the preheating chamber 14 by the other partition 11b. It is.

Inlet of the condensation chamber 13 is an inlet for introducing oil vapor which is forcibly discharged by the blower after the fine dust in the oil vapor is filtered by the filter in the process of discharging the oil vapor through the discharge passage in the drying chamber. ) Is formed. The introduction port 16 is connected to the end of the blower duct connected to the blower of the existing dryer.

The rear end of the condensation chamber 13 and the front end of the preheating chamber 14 are connected to the passage 17a so that the air passing through the condensing chamber 13 is introduced into the preheating chamber 14 and undergoes a preheating process. The preheated air passing through 14 enters the heating chamber 15 through the passage 17b and undergoes a heating process.

The partition 11a prevents the condensation efficiency from being lowered by suppressing the effect of the heat released when the preheater built in the preheating chamber 14 operates on the condensation chamber 13, and the partition 11b is a heating chamber ( The influence of the high temperature atmosphere in the condensation chamber 13 and the preheating chamber 14 in 15) is suppressed.

Either the front wall or the rear wall may be formed with a cashier 12 and a condensate outlet 18 so as to provide for the containment and withdrawal convenience of the cooling and preheating devices. In this case, the cashier window 12 is covered by the window cover 19a. The upper end of the housing 10 is covered by the top cover 19b to prevent external leakage of the fluid.

   As shown in FIG. 2, the solvent recoverer according to the present invention includes a cooling device 20 in the condensation chamber 13, and a preheating device 30 which is a conventional outdoor unit for a dryer in the preheating chamber 14. 15, the steam heater 40 is built.

The cooling device 20 is peeled off the window cover 19a and loaded through the open cashier 12, and the preheater 30 and the heating device 40 are peeled off the top cover 19b and loaded onto the housing 10. . After the device is loaded, the window cover 19a and the top cover 19b are closed and fastened with a bolt. The cashier window 12 may be omitted. In this case, before welding the front plate or the top plate of the housing 10, the cooling device 30 is first loaded in the condensation chamber 13, and the front plate or the back plate is welded.

The upper cover 19b is convenient to dualize the part covering the preheating chamber 15 and the part covering the heating chamber 15 in terms of the number of candidates for the individual chamber, the replacement of the interior, and the internal cleaning.

As illustrated in FIG. 3, the solvent recovery device is mounted on the existing laundry dryer 50, the inlet 16 is connected to the rear end of the air duct 51 of the dryer 50, and the heating chamber 15 is The lower end is connected to the return port 52 leading to the drying chamber of the dryer 50.

The oil vapor generated while the laundry is dried in the dryer 50 is forcibly sucked out by the draft fan 55 located below. In this process, dust such as seams mixed with steam and fiber filaments is filtered by the filter 54 loaded in front of the draft fan 55. The filtered oil vapor flows into the condensation chamber 13 through the inlet port 16 by the air duct 51.

In the condensation chamber 13, the solvent and moisture are condensed by the cooling device 20 in which the refrigerant is circulated, and the condensate falling to the bottom flows into the outlet 18.

Air whose temperature and humidity are lowered due to heat exchange with the condenser 20 is directed to the preheating chamber 14 through the passage 17a. In the preheating chamber 14, the refrigerant having a high temperature circulating in the cooling device 20 is preheated by the discharge heat while air passes through the preheating device 30 in circulation, and then passes through the passage 17b and then the heating chamber 15. Headed to).

The preheated air flowing into the heating chamber 15 is heated to a level comparable to the internal temperature of the drying chamber 53 by the steam heater 40 through which superheated steam flows, and is used as thermal energy for laundry drying.

4, the condensation chamber 13 and the preheating chamber 14 may use the housing 10 in a form in which the solvent recovery unit is parallel to the heating chamber 15. By adopting the housing 10, the left and right lengths can be shortened, thereby further miniaturizing the solvent recovery unit. In the case of the horizontal housing 10 described above, the cashier 12 and the window cover 19a of the cooling device 20 and the preheater 30 may be required on the front wall or the rear wall, but the condensation chamber 13 and When the preheating chamber 14 adopts the longitudinal housing 10, the upper cover 19b is also exposed, so that the upper end of the condensing chamber 13 is also exposed, thereby making it easy to enter and exit the cooling device 20. This makes it possible to omit cashiers and window covers, which may be necessary in the case of a transverse housing.

The solvent recovery device of the present invention described above can be supplemented with heat energy for drying laundry by refluxing the air after the condensation of solvent and moisture is preheated by a preheater and heating it to a level suitable for the internal atmosphere of the drying room. Therefore, the cost of replenishing the heat energy required to dry the laundry is reduced.

In addition, even if the air heated in the heating chamber immediately flows into the drying chamber, it does not lower the internal temperature of the drying chamber, it is possible to effectively dry the laundry.

In addition, it is a solvent recovery device that is independent of the laundry dryer, and is compact and can be easily mounted and operated without changing the appearance of the existing laundry dryer.
