Abstract

The present invention aims to provide an apparatus for recollecting oil mist and an organic solvent included in industrial exhaust gas with increased efficiency; and a method for recollecting oil mist and an organic solvent using the same apparatus. The apparatus comprises an air blower which transfers the exhaust gas by using high pressure; a heat exchanger on which a first recollection part recollecting the oil mist and the organic solvents such as VOCs is installed; a cooling water supplying means which supplies cooling water to the inside of a first body of the heat exchanger and circulates the cooling water; a transfer pipe having a temperature sensor on one side of an outer circumferential surface thereof; an electrical dust collector on which a second recollection part recollecting the oil mist and the organic solvents such as VOCs is installed; and a discharging pipe that discharges the exhaust gas from which the oil mist and the organic solvents such as VOCs are separated by the electrical dust collector to the outside.

Description

technical field

[0001] The present invention relates to an oil mist contained in industrial waste gas, an organic solvent recovery device and a method for recovering oil mist and organic solvent using the same, in particular to an oil mist contained in industrial waste gas, an organic solvent recovery device and an oil mist using the same , A recovery method of an organic solvent, which recovers from fiber dyeing, food processing, papermaking, food waste treatment, sewage treatment, metal processing, painting, paint manufacturing, lubricating oil manufacturing, etc. by electrostatic precipitation method based on cooling and corona discharge Organic solvents such as oil mist and VOCs contained in the exhaust gas emitted by industrial equipment, so that more excellent recovery efficiency can be obtained. Background technique

[0002] Generally speaking, the exhaust gas discharged from industrial equipment such as fiber dyeing, food processing, papermaking, food waste treatment...

Examples

Embodiment Construction

[0032] Hereinafter, details for implementing the present invention will be described in more detail with reference to the drawings.

[0033] refer to Figure 1 to Figure 7 , the oil mist contained in the industrial waste gas according to the present invention, the organic solvent recovery device, comprising: air blower (10), heat exchanger (20), cooling water supply equipment (30), moving pipe (40), electric precipitator (50), discharge pipe (60), thus, recycling is collected in industrial equipment (1 ) and organic solvents such as oil mist and VOCs contained in the exhaust gas moving to the conveying pipe (5) in the dust collecting hood (2) set in ).

[0034] Such as figure 1 As shown, the blower (10) is connected to the delivery pipe (5), so that the exhaust gas collected by the dust collection hood (2) arranged on the industrial equipment (1) and moved to the delivery pipe (5) is moved again by high pressure.

[0035]Also, preferably, the blower (10) is installed on th...
