Description
Technical field
The present invention relates to a kind of electroplating device, refer more particularly to the recycling and processing device of chromium plating waste gas in a kind of the plating.
Background technology
At present, electroplating industry occupies consequence in China's industry, mainly take chromium plating as main, be respectively applied in each chromium plating industry, as: engineering continues Ei, in coal mine machinery and the piston ring, in electroplating process, can produce a large amount of chromium plating waste gas that contains heavy metal, if enter in the atmosphere without timely processing, can cause serious environmental pollution, mostly be greatly for the processing of chromium plating waste gas in recent years and concentrate and be used chromic acid practical efficiency 20% in the electrodeposited chromium production process electroplating heavy metal in the waste gas, volatilization consumes chromic acid 30% in the waste gas, causes a large amount of wastes.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rate of recovery height, good purification, chromium mist waste gas recycling and processing device simple in structure.
In order to solve the problems of the technologies described above, the invention provides a kind of chromium mist waste gas recycling and processing device, comprise waste gas collection device and emission-control equipment, described waste gas collection device comprises slot exhaust hood, blast pipe and exhausting arm house steward, described blast pipe and slot exhaust hood and exhausting arm house steward are connection state, described exhausting arm house steward is arranged at the slot exhaust hood upper end, described slot exhaust hood lower end is provided with plating tank and has the slit, the slot exhaust hood upper end is provided with at least three exhausting holes, emission-control equipment comprises the waste gas spray purification tower, air outlet tube, chromium mist withdrawer and recovery liquid tank, described recovery liquid tank upper end is provided with blast cap.
As a further improvement on the present invention, described slot exhaust hood is provided with removable cover, and described removable cover comprises groove face cover plate and top shrouding.
As a further improvement on the present invention, described chromium mist withdrawer is made by polyvinyl-chloride plate material.
Adopt said structure, the present invention compared with prior art, its beneficial effect is:
Exhausting arm house steward is arranged at the slot exhaust hood upper end, described slot exhaust hood lower end is provided with plating tank and has the slit, the slot exhaust hood upper end is provided with at least three exhausting holes, the following current that can reach waste gas condensation solution is reclaimed, on all having, the off-gas liquid solution of recovery condensation down enters in the coating bath to trough rim exhausting bar sealing, effectively reclaim solution, reduced emission concentration.
Slot exhaust hood is provided with removable cover, and removable cover comprises groove face cover plate and top shrouding, has prevented that plating bath from dropping in the port area that has dwindled again coating bath on the anode, improved air suction efficiency.
Described chromium mist withdrawer is made by polyvinyl-chloride plate material, anti-chromic acid oxidation, and good seal performance, air resistance is less than GB grid type withdrawer, and life-time service does not stop up, and chromium mist recovering effect can reach 95%, and the chromium mist reclaims liquid and all gets back to the coating bath utilization.
Description of drawings
