BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifier for processing waste gas generated in a manufacturing process such as a semiconductor manufacturing process, a flat panel display device manufacturing process, and a solar cell panel manufacturing process.

Waste gas generated in a manufacturing process such as a semiconductor manufacturing process, a flat panel display device manufacturing process, and a solar panel manufacturing process includes harmful gases such as acidic gas generated from process equipment, reaction by-product particles, moisture and the like. The waste gas is discharged to the exhaust pipe of the process line through the combustion process and the water treatment process in the scrubber installed at the rear end of the process equipment.

The waste gas discharged from the scrubber contains moisture together with gas components and reaction by-product particles. Since the moisture has a temperature and a humidity higher than the internal temperature of the exhaust pipe, the moisture is condensed while the temperature inside the exhaust pipe lowers and the reaction by-product particles are also collected. The moisture condensed in the exhaust pipe becomes acidic to damage the exhaust pipe, shortening the replacement cycle of the exhaust pipe, and increasing the risk that the acid material is leaked when the exhaust pipe is replaced.

An object of the present invention is to provide a dehumidifier for process waste gas treatment capable of efficiently collecting and removing moisture contained in waste gas discharged from a scrubber.

The process waste gas treatment dehumidifier of the present invention is formed in a hollow box shape and has an outer housing having a waste gas inlet port, a waste gas outlet port, a first lower connection port and a first upper connection port, An inner housing having an inner waste gas inlet, an inner waste gas outlet, a first inner lower connector, a first inner upper connector, and a first tube penetrating hole, the inner housing being located inside the outer housing; A first cooling tube unit for cooling and collecting water contained in the waste gas by allowing the waste gas flowing in and flowing through the waste gas inlet to flow in a zigzag direction while contacting the first upper cooling tube and the first lower cooling tube in an upward direction, A first upper cooling tube coupled to the first lower connector and having a first lower cooling tube, A first lower connection flange coupled to one end of the sub cooling tube and a first upper connection flange coupled to the first upper connection port and coupled to the other end of the first upper cooling tube and the first lower cooling tube, And a second connection unit provided on the first connection unit.

The dehumidifier for the process waste gas treatment according to the present invention allows the waste gas discharged from the scrubber to pass through the cooling tubes spaced vertically and staggeredly apart to increase the contact area between the cooling tube and the waste gas, There is an effect to remove.

In addition, the dehumidifier for processing exhaust gas according to the present invention has the effect of condensing water effectively on the surface of the cooling tube by passing the waste gas discharged from the scrubber through a mesh-shaped low-temperature cooling tube.

Further, the dehumidifier for processing exhaust gas according to the present invention has the effect of making the flow of the waste gas smooth by causing droplets of water condensed on the surface of the cooling tube to fall downward.

Further, the dehumidifier for processing exhaust gas according to the present invention has the effect of reducing the phenomenon of condensation in the exhaust pipe because the exhaust gas is cooled by discharging the exhaust gas below the dew point.
