Description
Technical field the utility model relates to a kind of novel processing procedure waste gas recovering device, by this device, can reclaim solvent, reduction pollutant discharge amount, the solvent recovery of being volatilized in the present solvent type polyurethane resin processing procedure course of reaction and utilize the increase economic benefit again.
Background technology is present, and known solvent type polyurethane resin processing procedure pollution control equipment is to be made of discharge tube and active carbon adsorption tower.Pollutant is discharged by discharge tube after the absorption of active carbon adsorption tower by the consersion unit loss in the processing procedure course of reaction.But, activated carbon is limited to the adsorbance of solvent, when organic solvent use amount is big, the solvent discharge amount increases, cause active carbon adsorption saturated easily, the disposal ability deficiency causes the VOC discharging of (being called for short VOC), and common VOC has toluene, ethylbenzene, dimethylbenzene, formaldehyde, acetone, butanone etc., causes air pollution; Activated carbon regeneration may cause secondary pollution in addition, is converted into water by air pollution and pollutes; Activated carbon also can cause bazardous waste to pollute when discarded.All this kind situation all may cause more pollutions, increases social cost.
Summary of the invention is in order to overcome the situation that existing processing procedure uses the expensive poor efficiency of active carbon adsorption tower pollution control equipment, the utility model provides a kind of processing procedure waste gas recovering device, this processing procedure waste gas recovering device can not only effectively prevent organic solvent VOC discharging, and can reclaim solvent and reuse, reduce air pollution and increase economic benefit.
The purpose of this utility model is to adopt following technical scheme to realize:
A kind of novel processing procedure waste gas recovering device, described device comprises reaction procedure equipment, active carbon adsorption tower and the exhaust emission pipe that links to each other with the active carbon adsorption tower, described reaction procedure equipment comprises solvent storage tank, reactor and solvent measuring tank, solvent storage tank, reactor and solvent measuring tank three are connected in parallel by discharge tube, it is characterized in that: be provided with the waste gas recover between described reaction procedure equipment and active carbon adsorption tower.
Be placed with heat exchanger in the described waste gas recover, also be provided with the frozen water inlet on the described waste gas recover, the frozen water outlet, exhaust gas entrance, waste gas outlet and solvent discharge pipeline, wherein said frozen water inlet is connected to the inlet of heat exchanger, described frozen water outlet links to each other with the outlet of heat exchanger, described solvent discharge pipeline is connected with the waste gas recover, described exhaust gas entrance and solvent storage tank, the discharge tube outlet of reactor and solvent measuring tank three parallel connection links to each other, and described waste gas outlet links to each other by the inlet of discharge tube with described active carbon adsorption tower.
Described solvent discharge pipeline is provided with U type liquid seal device.
The outlet of described solvent discharge pipeline links to each other with recovery solvent collection bucket.
Described heat exchanger is the fin type heat exchanger.
Device of the present utility model, between existing polyurethane resin reaction procedure and pollution control equipment active carbon adsorption tower, one group of waste gas recover is set, to have the waste gas recover of the organic solvent elder generation of processing procedure discharging now by Specialty Design, use heat exchange effect fin type heat exchanger preferably, heat exchange area is big, frozen water machine supply chilled water, and frozen water is entered by inlet, with under the solvent condenses, the frozen water after the heat exchange is discharged by outlet after heat exchanger carries out heat exchange.The organic solvent that is not condensed behind the waste gas recover is not adsorbed the person at last and just discharges through discharge duct again through the absorption of active carbon adsorption tower.The solvent that the heat exchanger condensation is got off in the waste gas recover is by discharging of solvent discharge mouth and collection, and pipe arrangement is collected the organic solvent VOC that condenses below the waste gas recover.Estimate the waste gas recover organic solvent VOC removal efficient is reached 85～90%, 10～15% of residue is absorbed by the active carbon adsorption tower again.The waste gas recover mainly is made of the heat exchanger supply chilled water, sees through low temperature with organic solvent condensation and recycling.
Waste gas recover described in the utility model by heat exchange principle with organic solvent condensation and recycling, estimate the waste gas recover organic solvent VOC removal efficient is reached 85～90%, 10～15% of residue is absorbed by the active carbon adsorption tower again, can effectively reduce active carbon adsorption tower running cost, and increase prevention and cure of pollution efficient, regenerant is recycling, and equipment setting and maintenance cost are low and simple to operate, increases economic benefit.
