Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, forming machine waste gas residual heat reclaims and exhaust gas purification and treatment device, comprise screen pack 1, for forming machine waste gas higher for temperature and the lower fresh air of temperature being carried out the heat exchanger 2 of heat exchange, the waste gas input of heat exchanger 2 is connected with screen pack 1, flue gas output is connected with flue gas removing device for removing oil smoke in waste gas, and the fresh air output of heat exchanger 2 is communicated with forming machine.Flue gas removing device comprise be connected with heat exchanger 2 for the static flue gas removing device 3 that tentatively removes oil smoke the waste gas of going out from heat exchanger 2 and the spray flue gas removing device 4 for removing oil smoke in the waste gas after static flue gas removing device 3 fume eliminating be further connected with static flue gas removing device 3.Heat exchanger 2 is aluminum plate-fin type heat exchanger.Screen pack 1 is circulated throughout filter screen for stainless steel.Also comprise the steam cleaner 5 for cleaning greasy dirt in heat exchanger 2.Also comprise the activated carbon deodorizing device 6 be connected with flue gas removing device.Also comprise and being connected between heat exchanger 2 and forming machine for extraneous fresh air being introduced heat exchanger 2 and the fresh air after heat exchange in heat exchanger 2 being introduced the air-introduced machine I 7 of forming machine.The waste gas also comprised for being produced by forming machine introduces the air-introduced machine II 8 of heat exchanger 2.
Assembling process is: be connected with the flue gas output of forming machine by screen pack 1 by pipeline, the waste gas input of heat exchanger 2 is connected with screen pack 1, the flue gas output of heat exchanger 2 is connected with static flue gas removing device 3, static flue gas removing device 3 is connected with spray flue gas removing device 4, spray flue gas removing device 4 is connected with activated carbon deodorizing device 6, air-introduced machine II 8 can be located between screen pack 1 and heat exchanger 2, between screen pack 1 and the flue gas output of forming machine and between the flue gas output of heat exchanger 2 and static flue gas removing device 3, again by the fresh air output of pipeline by heat exchanger 2, air-introduced machine I 7, forming machine connects successively, the fresh air temperature of forming machine is transferred to for improving heat exchanger 2, air heating apparatus can be added between the fresh air output of heat exchanger 2 and forming machine.
The course of work is: the waste gas that forming machine produces through filter screen 1 enter heat exchanger 2 and fresh air heat exchange laggard enter static flue gas removing device 3 fume eliminating, enter to spray flue gas removing device 4 fume eliminating again, after activated carbon deodorizing device 6 eliminates the unusual smell, enter air again; Fresh air after the heat exchange of heat exchanger 2 enters forming machine through air-introduced machine I 7 and heats up to forming machine, and after heat exchanger 2 works certain hour, used vapour cleaning device 5 cleans it at set intervals, to ensure the operating efficiency of heat exchanger 2.
Forming machine waste gas is first circulated throughout filter screen through stainless steel, arrive heat exchanger again, fiber in forming machine waste gas and the large mist of oil dripped, through being circulated throughout filter screen, can be adsorbed on screen pack, playing the effect of part purification, large fiber and mist of oil is made to enter heat exchanger, blocking heat-exchanger, is circulated throughout the removable cleaning of getting off of filter screen, reuses.Owing to supplying the fresh air of forming machine, be through the air of efficient heat exchanger, so can reduce the load of forming machine heat-conducting oil furnace, the minimizing of conduction oil flow, can make Heat-transfer Oil Pump power consumption reduce more than 30%.Because the fresh air supplying forming machine is the air crossed through heat exchanger heats, the operating temperature in forming machine can be improved, can speed of production 2-3% be improved, and the feel of fabric also can further improve.The waste gas of forming machine discharge is the waste gas of high temperature, reach 170 DEG C, volume is large, and the optimum condition of industrial high-voltage static flue gas removing device is 60-70 DEG C, deliver to static flue gas removing device as the direct high-temp waste gas by forming machine and carry out purified treatment, effect is very undesirable, and easily causes the damage of the honeycomb electrode in oil fume eliminator.In the waste gas of forming machine discharge, small mist of oil can be ionized through the high voltage electric field of industrial high-voltage static flue gas removing device, adsorb, form larger mist of oil particle, be subject to the effect of Coulomb force in the electric field and be adsorbed on metallic plate, flow to draw-off tray, receive the effect of removing oil smoke, smell and reclaiming waste oil.Through the waste gas of high-voltage static flue gas removing device process, still with few fibers and mist of oil, waste gas in fountain flue gas removing device through water conservancy diversion and diffusion, contact with high-pressure water mist, the various fiber of water smoke condensable, mist of oil particle, with the fine water droplets of fiber, mist of oil, separated by drop separator, then be separated through oil water separator.Some forming machine, due to dyestuff and auxiliary agent, with stimulating the difficult smell smelt, can install the smell in activated carbon deodorizing device removal waste gas additional, not affect neighbouring resident living.
