Heat exchange device for purifying industrial oil smoke

Abstract

The invention discloses a heat exchange device for purifying industrial oil smoke. The heat exchange device comprises a shell and a heat exchange module. A support frame abuts below the heat exchangemodule, and two ends of the support frame are fixed to the shell. The heat exchange module is in the shape of an isosceles trapezoid and comprises a heat exchange pipeline and ladder-shaped first airdistribution pipes fixed to two ends of the heat exchange pipeline. Two sides of the shell are provided with second air distribution pipes, wherein the second air distribution pipes are matched with and abut against the first air distribution pipes. A locking structure for locking the first air distribution pipes is arranged on the front sides of the second air distribution pipes. Flue gas which needs to be cooled passes through the interior of the heat exchange pipeline, and gas and mist which are used for cooling pass through the exterior of the heat exchange pipeline, so that heat exchangeis realized, a good heat exchange effect and good flue gas tightness are achieved, and leakage of the flue gas is avoided. The heat exchange module is arranged to move on the support frame like a drawer, so that the second air distribution pipes are matched and abut against the first air distribution pipes, the locking structure is locked, the heat exchange device is convenient to disassemble andassemble, and the effects of maintenance and cleaning convenience are achieved.

Description

Technical field [0001] The invention relates to the technical field of electrostatic purification equipment, in particular to a heat exchange device used for industrial oil fume purification. Background technique [0002] Among the current industrial oil fume purification equipment, the more common is the electrostatic oil fume purifier, which charges the oil and dust in the industrial exhaust through an electric field, and then is adsorbed on the anode plate to achieve air purification. In the existing oil fume purifier, in order to avoid the high temperature of the exhaust gas, which may cause the temperature in the oil fume purifier to be too high, and even cause the problem of fire, a cooling device is added before the oil fume purifier to cool down, in order to achieve heat exchange. The sealing connection of the pipeline is fixed with the shell. Therefore, the existing cooling equipment is inconvenient to disassemble and assemble, and it is very troublesome to clean and mai...

AI Technical Summary

Problems solved by technology

In the existing oil fume purifier, in order to avoid the problem that the temperature in the oil fume purifier is too high due to the high temperature of the exhaust gas, and even cause fire, a cooling device is added in front of the oil fume purifier to achieve cooling. In order to achieve heat exchange The sealed connection of the pipeline is fixed with the shell, so the existing cooling equipment is inconvenient to disassemble, and it is very troublesome to clean and maintain in the later stage. Moreover, the current cooling equipment only uses refrigerant, The flue gas is used to exchange heat outside the heat exchange pipe, and the sealing performance of the flue gas is not high, and it is easy to leak
