Accompanying drawing explanation

Fig. 1 is cleaning treatment system structural representation described in the utility model.

Detailed description of the invention

Content of the present utility model is described below in conjunction with specific embodiments.

As it is shown in figure 1, be cleaning treatment system structural representation described in the utility model.Cleaning treatment system described in the utility model includes: inverted bowl-shape draft hood 10, cooler 20, air pump 30, electromagnetic valve switch 40, absorption cell 50, adsorber 60, waste collection pond 70 and the pipeline interconnected.Described draft hood 10 is disposed in the interior, its upper end is provided with the telescoping tube 11 of Telescopic movable, and by pipeline and cooler 20 UNICOM, cooler 20 other end connects air pump 30, form negative pressure when air pump 30 works, promote waste gas to be forced through cooler 20 and cool.Air pump 30 other end is linked with electromagnetic valve switch 40 by pipeline, and electromagnetic valve switch 40 is provided with the first exit 41 and the second exit 42, and the first exit 41 is inserted in the bottom of absorption cell 50, and the second exit 42 connects adsorber 60.Being provided with alkali liquor 51 in described absorption cell 50, waste gas middle acid substance and alkali liquor 51 are neutralized reaction, eliminate waste gas middle acid substance.Being additionally provided with first row QI KOU 52 on absorption cell 50, first row QI KOU 52 is directly and ambient atmosphere UNICOM, such Balance Absorption pond 50 internal gas pressure.Absorption cell 50 is additionally provided with observation panel 53, the liquid level situation of change of alkali liquor 51 can be observed by observation panel 53 1 aspect, can arrange hand-held acidometer at observation panel 53 judges the acid-base value situation of change of absorption cell 50 simultaneously, it is simple to grasp absorption cell 50 inner case.

Adsorber 60 that second exit 42 connects is internal fills activated carbon, and activated carbon has that adsorption capacity is big, the absorption advantage such as more thoroughly.Adsorber 60 is additionally provided with second exhaust port 62, second exhaust port 62 is directly and ambient atmosphere UNICOM, so equilibrium adsorption device 60 internal pressure, adsorber 60 is additionally provided with three terminal 61, three terminal 61 UNICOM's waste collection pond 70, the waste liquid 71 that in waste collection pond 70, storage is oozed out from adsorber 60.

Draft hood 10 described in the utility model, can removal easily, can the most directly carry out tail gas clean-up process directly by telescoping tube 11 and ventilated chamber air vent UNICOM.
