BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air compression system for recovering waste heat,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air compression system for recovering waste heat capable of generating hot water by using high-temperature, high-pressure compressed air generated in an air compressor as a waste heat source.

Generally, at the manufacturing site, an air compressor (air compressor) that generates air pressure necessary for the equipment is used.

The air compressor compresses air above atmospheric pressure to produce compressed air. The air compressors are classified into reciprocating type, screw type, and turbo type according to the compression type. Electric motors, engines, and turbines are used as power sources, but electric motors are mainly used.

In this way, the compressed air is raised to a very high temperature in the process of adiabatically compressing the atmospheric air at room temperature. Accordingly, a cooler (or an air cooler) is installed at the rear end of the air compressor to essentially cool the compressed air at a high temperature.

Specifically, in order to cool the air having a raised temperature, it requires cooling water supplied from the outside, such as a water-cooled type, or requires heat exchange with the outside air, such as an air-cooled type.

In the case of the water-cooled type, the cooling water circulation pump needs to be operated to supply the cooling water, and in the case of the air-cooling type, the air supply fan must be operated to supply the outside air.

As described above, the conventional technology requires a separate device for cooling the high-temperature air generated in the air compressor. In addition, since a separate device must be driven during the cooling process, the entire heat energy There arises a problem of consuming additional energy for the disposal of the heat energy.

Korean Registered Utility Model No. 20-0155956 entitled "Compressed Air Cooling Device for Air Compressor" (registered on June 7, 1999)

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art as described above, and it is an object of the present invention to provide an air compressor which does not require separate equipment for cooling high- And to provide an air compression system for recovering waste heat that can efficiently recover heat energy of high temperature compressed air and use it to generate hot water.

In order to clearly illustrate the present invention in the drawings, portions not related to the description are omitted, and like reference numerals are given to similar portions throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

1 is a conceptual diagram of an air compression system for recovering waste heat, which is an embodiment of the present invention.

The air compressor 110 of the present embodiment is a screw type air compressor, and the air compressor 110 needs to be supplied with oil for driving the screw.

In addition, the air compressor 110 is provided with a suction filter 120 for removing foreign matter from air supplied to be compressed.

The air taken in through the suction filter 120 is converted into high-temperature high-pressure compressed air in the air compressor 110 by a pair of screws.

Since the high-temperature and high-pressure compressed air contains an oil component for lubrication of the screw, it passes through the oil separator 130 (Oil Separator).

The oil separator 130 separates the oil component contained in the compressed air from the compressed air and the high temperature oil filtered by the oil separator 130 circulates to the air compressor 110 after passing through the oil cooler 140 .

The compressed air having passed through the oil separator 130 has a large amount of heat energy although the oil component is removed.

Meanwhile, a water storage tank 150 in which water is stored is separately provided.

A water circulation pipe 160 for circulating water provided in the water storage tank 150 is provided.

The present invention converts the water flowing along the water circulation pipe 160 into hot water using the thermal energy of the compressed air that has passed through the oil separator 130 as described above.

A heat exchange unit 170 for exchanging heat between compressed air and water is provided for the heat exchange.

In this embodiment, the compressed air having passed through the oil separator 130 is discharged through the compressed air discharge pipe 180, and the heat exchange unit 170 is branched from the compressed air discharge pipe 180.

Accordingly, the compressed air can be discharged to the outside without passing through the heat exchanging unit 170 or the heat exchanging unit 170 according to the water temperature of the water storage tank 150.

On the other hand, the water storage tank 150 is provided with a hot water discharge pipe 151 for discharging hot water stored in the water storage tank 150, and a cold water supply pipe 161 is connected to the water circulation pipe 160, Allow water to be replenished.

The present invention does not require any additional equipment for cooling the high-temperature compressed air generated by the air compressor 110, and thus does not consume additional energy to cool the high-temperature compressed air.

In addition, the present invention efficiently recovers heat energy possessed by high-temperature compressed air in the heat exchanging unit 170 and converts the water stored in the water storage tank 150 into hot water using the heat exchanging unit 170, thereby supplying hot water to various demands of the factory .

According to the experiment of the present inventor, when the air compressed in the air compressor 110 has a temperature of 50 to 60 ° C, the compressed air is used as an energy source of an air tank or various plant equipment lines after passing through the heat exchanging unit 170 , It was confirmed that it is possible to generate heating water at about 28 to 30 占 폚.

In addition, since the compressed air provided in the air tank or various plant facility lines has a low temperature, the generation of moisture is remarkably reduced, thereby reducing the failure rate of various automation facilities.

Of course, an air cooler or the like may be further added to the downstream end of the compressed air discharge pipe 180 in accordance with a request of the user.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the embodiments described above are intended to be illustrative, but not limiting, in all respects.
