Abstract
A chromium fog dust removing device includes that a fan 1 and a chromium plating device 11 are connected to form a chromium fog gas discharging system, and a waste pipeline and an air inlet pipe 6 are connected to form a chromium fog gas collection system. The chromium fog dust removing device is characterized in that a liquid storage tank 3 is arranged at the tail end of the chromium fog dust collection system, and deionized water sprayed from a nozzle 8 is used for recycling one part of chromium fog into the liquid storage tank 3. A filtering net 5 is used for filtering and condensing the other part of residual chromium fog to the filtering net, then the other part of residual chromium fog is sprayed by the nozzle 8, chromic anhydride condensed on the filtering net 5 is dissolved and recycled into the liquid storage tank 3, the deionized water containing chromium in the liquid storage tank is extracted into tank liquid in a chromium tank 11 through a titanium pump 9 to be reutilized, and fresh deionized water is compensated in the liquid storage tank 3. The chromium fog dust removing device greatly improves chromium fog processing capability, improves chromic anhydride utilization ratio and reduces pollution to environment.
Description
Technical field
The utility model relates to the deduster field, is specifically related to chromium mist deduster.
Background technology
Deduster in the market is to adopt single nylon mesh to filter; Let the condensation and attached to nylon mesh when the nylon mesh of chromium mist; Handle not thoroughly, have a lot of tiny chromium mists can see through filter screen and fly in the atmosphere environment is polluted, contain a large amount of hexavalent chromiums in the outbound chromium mist; And can not recycling, be very big waste to production cost.
Summary of the invention
Handle not thorough in order to solve former chromium mist deduster to the chromium mist; Cause the pollution of atmosphere and the waste of a large amount of hexavalent chromium chromic anhydrides; The technical scheme of the utility model is: a kind of chromium mist dust arrester; Comprise that exhaust blower 1 and chrome plating equipment 11 connect into chromium fog body discharge system, exhaust piping and blast pipe 6 and connect into chromium fog body gathering system; It is characterized in that: the tail end in chromium fog body gathering system is provided with liquid reserve tank 3, and the deionized water that nozzle 8 sprays come out is used for a part of chromium mist is recycled to liquid reserve tank 3; Screen pack 5 filters the residual chromium mist of another part, be condensed on the screen pack 5; And then by nozzle 8 sprays; The chromic anhydride dissolving of condensation on the screen pack 5 is recycled in the liquid reserve tank 3; The deionized water that liquid reserve tank 3 is included chromium is with utilizing in titanium pump 9 suction chromium grooves 11 tank liquors again, and in liquid reserve tank 3, replenishes fresh deionized water.
Described screen pack 5 is the 2-5 layer.
Described screen pack 5 materials are nylon or cotton or fiber.
Described screen pack 5 can regularly clean or replace through transparency window 2.
Described titanium pump 9 is established independent switch, can independently control the flushing to screen pack 5, washes to the liquid reserve tank 3 chromic anhydride of condensation on the screen pack 5 multilayer nylon ropes for use.。
Described screen pack 5 is provided with transparency window 1, liquid reserve tank 3 is provided with transparency window 37, the nozzle 8 outer transparency windows 24 that are provided with, and wherein transparency window 1 is detachable with transparency window 24, is convenient to observe or disassembly, cleaning screen pack 5 and nozzle 8.
In a word, done on the basis of existing technology below main improvement:
1, before the chromium mist is through screen pack 5, adopts nozzle 8 usefulness deionized waters to spray continuously, let a part of chromium mist be condensed in the liquid reserve tank 3;
2, liquid reserve tank 3 is contained chromic liquid with utilizing as replenishing in the titanium pump 9 suction chromium grooves 11 again.
3, the utility model is the mode that adopts multiple filtration; And the 5 pairs of gas liquefaction chromic anhydrides from the chromium fog body that the chromium groove comes out of 2 to 5 layers of screen pack that add filtering material nylon, cotton, fleece composition carry out effective filter freezing; To guarantee reaching national requirements for environmental protection in least limit through chromic anhydride content in the gas behind the utility model.Titanium pump 9 is set up independent switch, continuously screen pack 5 is washed, and washes to the liquid reserve tank 3 chromic anhydride of condensation on the screen pack 5 multilayer nylon ropes for use.
4, transparency window 1 is installed, makes things convenient for regularly cleaning or replacing of screen pack 5.
Screen pack 5 will regularly clean:
1) cleaned through the inner spray equipment spiral nozzle of chromium day with fog 8 usefulness deionized waters in 2-3 days;
2) the 2-3 month must clean by dismounting filter screen 5.
3) must change filter screen 5 after 1 year.
5, liquid reserve tank 3 begins to adorn deionized water, note to observe the color of water, treats that liquid concentration can be extracted into the liquid in the liquid reserve tank 3 in the coating bath 11 when identical with coating bath 11 tank liquor concentration, and the deionized water of annotating in the storage tank 3 again.
6, this device blast pipe 6, and going up the pipeline that links to each other with exhaust blower 1 is air outlet, and blast pipe 6 links to each other with chrome plating equipment; Air outlet is through blower fan 1 back and atmosphere.Export an available flexible pipe with to 11 times grooves of chrome plating equipment from ball valve 10 in addition.
Description of drawings:
Fig. 1 is the structural representation of the utility model device.
The specific embodiment:
The utility model is installed on correct position between chrome plating equipment 11 and body of wall, couples together with the pvc pipe of diameter 200mm and chrome plating equipment and blower fan 1, pipeline connects the general PVC of employing welding manner, connects with CARBURIZING FURNACE FOR STAINLESS FASTENER and also can.
Comprise that exhaust blower 1 and chrome plating equipment 11 connect into chromium fog body discharge system, exhaust piping and blast pipe 6 and connect into chromium fog body gathering system; It is characterized in that: the tail end in chromium fog body gathering system is provided with liquid reserve tank 3, and the deionized water that nozzle 8 sprays come out is used for a part of chromium mist is recycled to liquid reserve tank 3; Screen pack 5 filters the residual chromium mist of another part, be condensed on the screen pack; And then by nozzle 8 sprays; The chromic anhydride dissolving of condensation on the screen pack 5 is recycled in the storage tank 3; The deionized water that reservoir 3 is included chromium is with utilizing in titanium pump 9 suction chromium grooves 11 tank liquors again, and in liquid reserve tank 3, replenishes fresh deionized water.Increased substantially the disposal ability of chromium mist like this, improved the utilization rate of chromic anhydride, reduced pollution environment.
