Abstract
The utility model discloses a precious metal tail gas recovering and purifying system comprising a recovery system and a purification system. The key points are as follows: the recovery system comprises two or a plurality of recovery containers which are connected in sequence, such as a primary recovery container, a secondary recovery container and the like, an inlet pipe at the upper end of the recovery containers, an outlet pipe, and a dewatering switch at the lower part of the recovery containers; the purification system comprises two or a plurality of purification containers which are connected in sequence, such as a primary purification container, a secondary purification container, a three-level purification container and the like, an inlet pipe at the upper end of the purification containers, an outlet pipe and a dewatering switch at the lower part of the purification containers, and the purification system is connected with a vacuum pump and an acid fog tower high-altitude discharging device. The precious metal tail gas recovering and purifying system has a simple structure, is low in cost and can recover precious metal in tail gas and purify the tail gas to the maximum degree.
Description
Technical field
The utility model relates to a kind of equipment that reclaims purifying noble metal from the waste material of noble metal, belongs to noble metal chemical extraction separation technology field.
Background technology
Now in the purification and extraction process process of noble metal, contain and add the chloroazotic acid heating for dissolving when purifying in the noble metal waste material, in the process of reaction, can produce a large amount of tail gas, comprise waste gas and the water-fast gas that also has minute amount of noble metal that energy is water-soluble, for any discharging that prevents waste gas pollutes air, simultaneously for avoiding having the unnecessary loss of gas of minute amount of noble metal, the utility model provides a kind of noble metal tail gas recycle cleaning system, recovery and further purification the, maximum benefitization as much as possible by tail gas.This noble metal tail gas recycle cleaning system is simple in structure, cost is low, can at utmost recycle tail gas.
The utility model content
Technical problem to be solved in the utility model is, provide a kind of simple in structure, cost is low, can at utmost recycle the noble metal tail gas recycle cleaning system of tail gas.
For solving above technical problem, the technical solution of the utility model is: a kind of noble metal tail gas recycle cleaning system, comprise recovery system and cleaning system, key is: recovery system comprises two or more returnable that connect successively, as one-level returnable, secondary recovery container etc., as described in the returnable upper end inlet tube, outlet and below cock of water drain; Cleaning system comprises two or more purifying vessels that connect successively, as first class purification container, secondary purification container, three grades of purifying vessels etc., as described in the cock of water drain established of inlet tube, outlet and the purifying vessel bottom of purifying vessel upper end, be connected with vacuum machine and water tank high altitude discharge device after the described cleaning system in turn.
The beneficial effects of the utility model: a kind of noble metal tail gas recycle cleaning system, comprise recovery system and cleaning system, key is: recovery system comprises two or more returnable that connect successively, as be one-level returnable, secondary recovery container etc., as described in returnable upper end inlet tube, outlet and below cock of water drain, fill water in the described returnable, after having the condensation of minute amount of noble metal waste gas in the tail gas, reclaim by following cock of water drain; Cleaning system comprises two or more purifying vessels that connect successively, as the first class purification container, the secondary purification container, three grades of purifying vessels etc., the inlet tube of described purifying vessel upper end, the cock of water drain that establish outlet and purifying vessel bottom, fill alkaline matter in the purifying vessel, with in the acidic materials in the tail gas and after, discharge by following cock of water drain, be connected with vacuum machine and acid mist purifying column high altitude discharge device after the described cleaning system in turn, like this through behind the reclaiming clean from level to level, waste gas is neutralized in the tail gas, useful tail gas reclaims by recovery system, can not cause the pollution of air and the waste of tail gas, make the maximization of production interests.
Description of drawings
Below in conjunction with Figure of description the utility model is done further detailed description, wherein:
