Description

Air dehumidifier

The present invention relates to an air dehumidifying apparatus, and more particularly, by passing compressed air heated by a heater through a cold sink cooled by a thermoelectric element, air to remove moisture and dust in the compressed air using condensation. It relates to a dehumidifier.

Since a general compressor uses a lot of oil, compressed air contains lubricating oil, miscellaneous dust and water vapor, and when this oil, dust and water vapor is transferred to a boiler and a measuring device, a bad effect is caused to the boiler and a measuring device. do.

Accordingly, a dehumidifying apparatus for removing moisture and dust in the air is used. As an example, a dehumidifying apparatus such as silica gel type and seawater cooling type is used. The silica gel type air dehumidifying apparatus uses silica gel. An air dehumidifier in which a water vapor is adsorbed and removed from wet air by a capillary phenomenon, which has two adsorption towers containing silica gel, and is operated as a predetermined cycle so that each adsorption tower alternately adsorbs and releases water vapor. Accordingly, the silica gel type air dehumidifier requires two adsorption towers as described above, resulting in an increase in size of the apparatus. A sea water cooling air dehumidifier is a type of air dehumidifier in which wet air is cooled by sea water to condense water vapor contained in the wet air to separate water vapor from the air. It is impossible to cool the furnace and the performance is poor.

An object of the present invention for solving the problems as described above is to pass the compressed air heated by the heater to the cold sink cooled by the thermoelectric element, by using the condensation of water vapor in the moisture and dust and odor in the compressed air It is to provide an air dehumidifier to be removed.

An embodiment of the present invention for achieving the above object will be described with reference to the accompanying drawings, FIGS. 1 to 3.

Figure 1a is an exploded perspective view showing a cold sink of the air dehumidifier according to the present invention, Figure 1b is a cross-sectional view showing an air dehumidifier according to the present invention, Figure 2 is a view showing an example of use of the air dehumidifier according to the present invention to be.

As shown in FIG. 1A, the air dehumidifying apparatus according to the present invention includes a plurality of thermally conductive first plates 14 having large diameter through holes 12 and located in the through holes 12 formed in the first plates 14. The heat conductive second plate 18 in which the small holes 16 are arranged is repeatedly arranged alternately, and a cold sink 10 having a compressed air inlet pipe 22 connected to one end thereof and a compressed air discharge pipe 24 connected to the other end thereof. ), A heat conduction semiconductor element 30 having a heat absorbing portion in close contact with the cold sink 10, a heat dissipation fin 42 and a blowing fan 44 provided at a heat generating portion of the heat conduction semiconductor element 30, and the cold sink. Heater 50 installed on the outer circumference of the compressed air inlet pipe 22 connected to the 10 and connected to the discharge pipe 24 of the lower portion of the cold sink 10 is connected to the collecting container 62 to collect moisture It consists of a drain pipe 64.

Meanwhile, reference numeral 66 in the drawing denotes a valve for discharging water including dust collected in the collecting container 62 to the outside of the collecting container 62.

According to the dehumidifying apparatus according to the present invention configured as described above, as shown in FIG. 2, compressed air including moisture, dust, and oil discharged from the compressor 70 passes through the dehumidifying apparatus 80. The air introduced into the 80 is heated while passing through the inlet pipe 22 heated by the heater 50, as shown in FIG. 1B, and then the cold sink cooled in close contact with the endothermic portion of the thermoelectric semiconductor element 30. As condensation passes through (10), dust containing oil is discharged to the drain pipe 64 together with the water generated by the condensation of moisture, and the compressed air is a device or a work site that requires compressed air through a pipe or the like. After supplying to the 90, and is circulated to the compressor 70, the heat generated by the heat generating portion of the thermoelectric semiconductor element 30 is cooled by the heat dissipation fin 42 and the blowing fan (44).

In the cold sink 10, since the large holes 12 and 16 are arranged alternately with the small ones, the residence time of the compressed air in the cold sink 10 is increased and the contact area with the cold sink 10 is increased. By expanding, the condensation rate of compressed air is improved.

In addition, as described above, since the dust, moisture, oil, etc. contained in the air are removed together with the water generated by the condensation of moisture, the air dehumidification to the gas discharge pipe of the food storage tank in the food composting and recycling system for regenerating food waste. When the device 80 is installed, odor generated from food can be removed by condensation while passing through the dehumidifying device 80.

Therefore, according to the present invention, since moisture, dust, odor, and oil contained in the air are completely removed, the occurrence of malfunction due to moisture of a device using compressed air is prevented, and the air in the workplace is clean and odor is Removed, using the thermoelectric semiconductor element is greatly reduced the volume and weight of the dehumidification device is not limited by the installation space and location, and the moisture condensation rate by using a cold sink and a thermoelectric semiconductor element formed with a long residence time of air This improves the removal efficiency of dust and water, and keeps the temperature of the cold sink constant, thus preventing freezing due to excessive cooling of the cold sink and reducing the dew condensation rate caused by the cold sink's heating. There is.
