The technical solution of the utility model is as follows:
A kind of chromium mist reclaiming clean all-in-one, comprises reclaiming clean storehouse and cycles of washing pond; Described reclaiming clean storehouse be provided with successively from top to bottom chromium mist trapping district, except fog-zone and washing, purifying district; Described chromium mist trapping top, district is provided with chromium mist entrance, and inside is provided with the stainless steel woven wire for trapping chromium mist; Described communicating except fog-zone and described chromium mist trapping district, described removing in fog-zone is provided with the polyhedron empty ball filler for removing moisture; Top, described washing, purifying district is provided with the first mouth spray and the 2nd mouth spray for spraying neutralizing agent and reductive agent to described washing, purifying district, the adjustable waste gas PH value of described neutralizing agent, and described reductive agent is for becoming positive trivalent by carcinogenic positive hexavalent chrome reduction; Being provided with cycles of washing pond below described washing, purifying district, described cycles of washing pond by pump washings is transmitted back to described first mouth spray and the 2nd mouth spray recycles; What the pure air after described washing, purifying district purifies was back to described reclaiming clean storehouse goes out air port, is discharged in air.
Further, described pump is submerged pump.
Further, it is provided with the online instrument of PH in described cycles of washing pond.
Further, neutralizing agent feed-pipe and reductive agent feed-pipe it is provided with in described cycles of washing pond, described neutralizing agent feed-pipe and reductive agent feed-pipe are provided with magnetic valve, described magnetic valve, pump instrument online with PH is all connected with PLC, when the PH Value Data over range that the online instrument of PH collects, PLC controls the add-on of described neutralizing agent and reductive agent by described magnetic valve.
The beneficial effects of the utility model: chromium mist withdrawer, mist eliminator, acid mist spray washing tower set are designed in a reclaiming clean storehouse by the utility model, compact construction, floor space are little, chromium mist is through trapping district through chromium mist successively from top to bottom, except fog-zone and washing, purifying district obtain chromium acid anhydride and pure air after processing, Recovery Purifying is rapidly and efficiently; And in washing, purifying district, increase reductive agent positive hexavalent chrome reduction is become positive trivalent, eliminate carcinogenic hidden danger. In addition, cycles of washing pond is set bottom reclaiming clean storehouse to realize recycling of scavenging solution, reduces the loss of neutralizing agent and reductive agent, again further the online instrument of PH auxiliary under, jointly controlling the addition of neutralizing agent and reductive agent with PLC, make whole reaction more abundant, decontamination effect improving is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Element numbers illustrates: chromium mist entrance 1, chromium mist trap district 2, chromium acid anhydride outlet 3, except fog-zone 4, first mouth spray 5, washing, purifying district 6, pump 7, the online instrument 8 of PH, cycles of washing pond 9, the 2nd mouth spray 10, go out air port 11.
Embodiment
By particular specific embodiment, enforcement mode of the present utility model being described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present utility model and effect easily.
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of chromium mist reclaiming clean all-in-one, comprises reclaiming clean storehouse and cycles of washing pond 9, and described reclaiming clean storehouse is provided with chromium mist trapping district 2 from top to bottom successively, except fog-zone 4 and washing, purifying district 6; Chromium mist trapping district 2 is provided with chromium mist entrance 1, the chromium mist produced after plating enters in chromium mist trapping district 2 from chromium mist entrance 1, the trapping of chromium mist is provided with stainless steel woven wire in district 2, for trapping chromium mist, when chromium mist enters into chromium mist trapping district 2, during through Stainless Steel Cloth, it is attached on Stainless Steel Cloth grid under inertial effect and occlusion effect, not open close enter chromium mist process in, tiny chromic acid particle progressively increases and condenses into chromium acid anhydride, and be rolled down along steel wire grid, by chromium acid anhydride outlet 3 discharge being located at outside reclaiming clean storehouse. The waste gas left over after chromium mist traps then enters except fog-zone 4, and except being provided with polyhedron empty ball filler in fog-zone 4, the water smoke in waste gas impinges upon and is captured down on polyhedron empty ball, is gone out by the moisture in waste gas. Continue to flow downward through the remainder of exhaust gas except fog-zone 4, enter washing, purifying district 6, top, washing, purifying district 6 is provided with for spraying neutralizing agent and reductive agent first mouth spray 5 and the 2nd mouth spray 10 to washing, purifying district 6, regulate the PH value of waste gas, and by above-mentioned reductive agent, the chromium of carcinogenic positive sexavalence is reduced into positive trivalent; It is provided with cycles of washing pond 9 below washing, purifying district 6, cleans the washings after waste gas and be flowed in cycles of washing pond 9, be transmitted back to the first mouth spray 5 through pump 7 by circulating line and the 2nd mouth spray 10 recycles.
