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 plating.
Background technology
At present, electroplating industry occupies consequence in China's industry, based on mainly with chromium plating, it is respectively used in each chromium plating industry, as: engineering continues Ei, in coal mine machinery and piston ring, in electroplating process, the substantial amounts of chromium plating waste gas containing heavy metal can be produced, if entering in air without timely process, serious environmental pollution can be caused, process for chromium plating waste gas in recent years is mostly and the heavy metal in plating waste gas is carried out concentration and is used, chromic acid practical efficiency 20% in electrodeposited chromium production process, volatilization in waste gas consumes chromic acid 30%, cause substantial amounts of waste.
Content of the invention
The technical problem to be solved in the present invention is to provide the chromium mist waste gas recovery processing means of a kind of rate of recovery height, good purification, simple in construction.
In order to solve above-mentioned technical problem, the invention provides a kind of chromium mist waste gas recovery processing means, including waste gas collection device and emission-control equipment, described waste gas collection device includes slot exhaust hood, blast pipe and exhausting arm house steward, described blast pipe is connection status with slot exhaust hood and exhausting arm house steward, described exhausting arm house steward is arranged at slot exhaust hood upper end, described slot exhaust hood lower end is provided with electroplating bath and has gap, slot exhaust hood upper end is provided with at least three exhausting hole, emission-control equipment includes waste gas spray purification tower, discharge pipe, chromium mist recover 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 includes groove face cover plate and top shrouding.
As a further improvement on the present invention, described chromium mist recover is made by polyvinyl-chloride plate material.
Using said structure, compared with prior art, it has the beneficial effects that the present invention:
Exhausting arm house steward is arranged at slot exhaust hood upper end, described slot exhaust hood lower end is provided with electroplating bath and has gap, slot exhaust hood upper end is provided with at least three exhausting hole, the following current that can reach waste gas condensation solution is reclaimed, reclaim the off-gas liquid solution of condensation all have on down arrive trough rim exhausting bar sealing and enter in coating bath, effective recovery solution, decreases concentration of emission.
Slot exhaust hood is provided with removable cover, and removable cover includes groove face cover plate and top shrouding, it is therefore prevented that plating solution drops in the aperture area reducing again coating bath on anode, improves air suction efficiency.
Described chromium mist recover is made by polyvinyl-chloride plate material, and resistance to chromic acid aoxidizes, good seal performance, and air resistance is less than GB grid type recover, and Long-Time Service does not blocks, and chromium mist recovering effect is up to 95%, and chromium mist recovered liquid empties back into coating bath and utilizes.
Brief description
The structural representation of the chromium mist waste gas recovery processing means for invention for the Fig. 1；
Fig. 2 is the structure chart of slot exhaust hood described in embodiment.
In figure: 1-slot exhaust hood, 2-blast pipe, 3-exhausting arm house steward, 4-waste gas spray purification tower, 5-discharge pipe, 6-chromium mist recover, 7-reclaims liquid tank, 8-blast cap, 9-removable cover, 10-exhausting hole, 11-electroplating bath, 12-groove face cover plate, and 13-comes directly towards shrouding.
Detailed description of the invention
The present invention will be further described in detail below in conjunction with the accompanying drawings.
nullShown in Fig. 1 and Fig. 2，A kind of chromium mist waste gas recovery processing means，Including waste gas collection device and emission-control equipment，Described waste gas collection device includes slot exhaust hood 1、Blast pipe 2 and exhausting arm house steward 3，Described blast pipe 2 and slot exhaust hood 1 and exhausting arm house steward 3 are in connection status，Described exhausting arm house steward 3 is arranged at slot exhaust hood 1 upper end，Described slot exhaust hood 1 lower end is provided with electroplating bath 11 and has gap，Slot exhaust hood 1 upper end is provided with at least three exhausting hole 10，Described slot exhaust hood 1 is provided with removable cover 9，Emission-control equipment includes waste gas spray purification tower 4、Discharge pipe 5、Chromium mist recover 6 and recovery liquid tank 7，Described recovery liquid tank 7 upper end is provided with blast cap 8，Described chromium mist recover 6 is made by polyvinyl-chloride plate material，Described removable cover 9 includes groove face cover plate 12 and top shrouding 13.
During work, the waste gas that electroplating bath 11 produces is entered waste gas spray purification tower 4 by slot exhaust hood 1, waste gas spray purification tower 4 sprays atomized liquid, then under the fan action that waste gas connects at discharge pipe 5s, flow upwardly toward blast cap 8 via reclaiming liquid tank 7, whole line chromium plating exhaust gas fan configuration power can reduce 20%-30%, accomplish to save energy and reduce the cost, decrease waste gas discharge, now liquid separates further, the pernicious gas liquefaction that will contain in waste gas, ensure that waste gas is up to state standards, in reclaiming liquid tank 7, recovered liquid is through being discharged to middle control slot simultaneously, can return in coating bath containing chrome liquor after process, recycle.
