Abstract
The utility model provides a chromic acid waste gas purification recovering device for washing chromic spray net grate recovering device relating to a device for electroplating waste gas purifying, recovering and processing. The utility model adds an autoprocessing system to the chromic spray net grate; a spray header is arranged on the upper part of the chromic spray net grate; two pressure testing openings of the U-shaped manometer are arranged on the top and bottom of the chromic spray net grate; a spray pump supplies flushing water through pipe-lines which are provided with valves. The utility model solves the problems of the difficult disassembly and flushing of the chromic spray net grate and the effective normal operation of the recovering device existing in the present chromic acid waste gas purification recovering device; the cost of chrome plating and three wastes treatment is reduced.
Description
The utility model provides a kind of chromic acid waste gas that adds washing chromic spray net grate system to purify withdrawer, is the device that the chromic acid waste gas that produces in the electroplating process is purified recycling.
At present, China extensively adopts the chromic acid waste gas purification withdrawer by the design of CT801 standard map that the chromic acid waste gas that produces in the electroplating process is purified recycling.In use chromium mist net grid are easily blocked for this device, and net grid and gripping plate must remove flushing.The work of unpicking and washing the net grid is not only tired not only dirty but also pollution is arranged, and also causes second environmental pollution simultaneously.If irregularly unpick and wash, the obstruction of net grid will go from bad to worse, and the exhausting resistance strengthens, and the air draught of coating bath place reduces, even causes the net grid to break, and cleaning action lost efficacy.Because unpick and wash difficulty, the maintenance labor capacity is big and pollution is arranged, and some factory often takes place the net grid are removed, make to purify withdrawer and become illusory.
The purpose of this utility model is to solve net grid flushing difficult problem, makes rinse-system and this withdrawer integrated, designs a kind of chromic acid waste gas that adds washing chromic spray net grate system and purifies withdrawer.
The utility model is achieved in that Fig. 1 has provided structural representation, is made up of recovery holder 1, chromic acid waste gas import 2, air chamber 3, chromium mist net grid 4, blower fan 5 according to original design.The utility model has been installed the spray irrigation system to chromium mist net grid, establishes spray header 6, and two pressure detection mouths of U-shaped pressure warning unit 8 are installed in about the net grid, and spray pump 7 is by the water of valve 9 controls for flushing.
Further specify working process of the present utility model below in conjunction with accompanying drawing 1: blower fan 5 is drawn into mist of chromic acid in the air chamber 3 by exhaust gas inlet 2 as the propulsion source of exhausting, and the chromium mist is condensed in the drop inflow recovery holder 1 by the detention of laminated plastics net grid 4.When pressure difference reaches 15～20mm mercury slug before and after U-shaped pressure warning unit 8 indicates the withdrawer filter screen, filter screen part obstruction is described, open flush valve 9 and spray pump 7 this moment, and spray liquid is delivered to spray header 6, the net grid are washed, and washing fluid flows into and reclaims in the holder 1.Regularly the recovery liquid pump in the holder 1 is gone in the treatment trough 11 to recycle then with reclaiming pump 10.Valve 9 can adopt magnetic valve by the manometric detection signal of U-shaped spray pump 7 to be controlled automatically.Reclaiming holder 1 is replaced by bigger storage tanks in fact.
The utility model has solved chromium mist net grid to be difficult to disassembly, cleaning and to be difficult to keep efficiently purify the recovery problem.Applying of this complete equipment, not only make the chromium mist environmental pollution problem when electroplating obtain solving more completely, also for the efficient recovery chromic acid provides effective device, the cost that the chromium plating and the three wastes are handled reduces, and has remarkable economic efficiency and social benefit.
Embodiment of the present utility model as mentioned above, according to standard map CT801, the vertical L type of former withdrawer structure is constant substantially, only installs sprinkling system additional and gets final product.Former horizontal W type is installed additional chromium mist net grid sprinkling system after vertical and is got final product by horizontal converting to.The scheme of our factory enforcement has at present adopted the double purified device as shown in Figure 2.The mist of chromic acid pneumatic transmission that is about to rough purification is gone into spray column 12, and air-flow contacts with the water surface downwards, makes progress through the filter packing layer again to airborne release again.Reached the purpose of high purification like this.
