Abstract
The utility model relates to a device used for precious-metals recovery in a metallurgy process. The device comprises a resistance furnace, a metal gas-collecting hood, a tube type heat exchanger, a recovery tank and a centrifugal fan, wherein the metal gas-collecting hood is positioned above the resistance furnace and is connected with an inlet at the upper part of the tube type heat exchanger, an outlet at the lower part of the tube type heat exchanger is connected with the recovery tank, and the centrifugal fan is arranged below the tube type heat exchanger. The metal gas-collecting hood is utilized for collecting gas volatile in a centralized manner, the tube type heat exchanger is used for reducing the temperature of the volatile for enabling the volatile to be settled and attached to the interior of the tube, and then to flow into the recovery tank below after being subjected to spray washing for being recovered and treated at regular time, so that the loss of precious metals such as gold and silver is avoided, and pollution to the environment is not caused as well, therefore the device has highly popularization and application value.
Description
Technical field
The utility model belongs to metallurgical technology field, is specifically related to a kind of device reclaiming for metallurgical technology precious metal.
Background technology
In metallurgical technology, in the gold mud of recovery, contain a large amount of zinc simple substance.Before smelting, need with resistance furnace, it to be heated with so that zinc is oxidized to ZnO evaporate in air, thereby realize zinc removal of impurities from gold mud.Yet in the time of resistance furnace heating, a small amount of gold and silver also can follow the ZnO of gaseous state to be taken out of together, caused the loss of precious metal also to pollute environment simultaneously.
Utility model content
The utility model object is to provide a kind of device that reclaims precious metal for metallurgical technology.
For achieving the above object, the utility model adopts following technical scheme:
A kind of device reclaiming for metallurgical technology precious metal, it comprises resistance furnace, metal gas skirt, shell and tube heat exchanger, accumulator tank and centrifugal blower, wherein, described metal gas skirt is positioned at resistance furnace top, metal gas skirt is connected with tubular heat exchanger top import, and the outlet of tubular heat exchanger below connects accumulator tank; Described tubular heat exchanger below arranges centrifugal blower.
Concrete, described accumulator tank is connected with tubular heat exchanger top import through corrosion protection pump; The water of condensation of described tubular heat exchanger is imported and exported and is connected with circulating water channel through recycle pump.
The effect of centrifugal blower is to regulate and to accelerate flue gas (the being metal volatile matter) flow velocity in shell and tube heat exchanger.
Compared to the prior art, the beneficial effects of the utility model:
Utilize metal gas skirt by volatile gas centralized collection, thereby the temperature that then reduces volatile matter by shell and tube heat exchanger makes it sedimentation and is attached in pipe, by spray washing, flow in the accumulator tank of below again, can regularly recycle, avoided like this loss of the precious metals such as gold and silver, do not cause environmental pollution, have application value simultaneously yet.
Accompanying drawing explanation
Fig. 1 is the structural representation of device described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, a kind of device reclaiming for metallurgical technology precious metal, it comprises resistance furnace 1, metal gas skirt 2, shell and tube heat exchanger 5, accumulator tank 4 and centrifugal blower 7, wherein, described metal gas skirt 2 is positioned at resistance furnace 1 top, metal gas skirt 2 is connected with tubular heat exchanger 5 top imports, and tubular heat exchanger 5 below outlets connect accumulator tank 4; Described tubular heat exchanger 5 belows arrange centrifugal blower 7.Described accumulator tank 4 is connected with tubular heat exchanger 5 top imports through corrosion protection pump 8; The water of condensation import and export of described tubular heat exchanger 5 is connected with circulating water channel 6 through recycle pump 3.
During use, in accumulator tank 4 and circulating water channel 6, fill in advance part water.Start recycle pump 3, the water in circulating water channel 6 is circulated at pipe layer through the water of condensation import and export of tubular heat exchanger 5, play in advance condensation cooling effect, open centrifugal blower 7 simultaneously.Now, resistance furnace 1 adds thermogenetic metal volatile matter and through metal gas skirt 2, enters the shell of tubular heat exchanger 5, in decline process, carries out heat exchange with the water of condensation that circulates, gradually sedimentation and being attached in pipe.Start corrosion protection pump 8, water in accumulator tank 4 is flowed at the shell circulated sprinkling of tubular heat exchanger 5, so just sedimentation and the metal volatile matter being attached in pipe can be rinsed in the accumulator tank 4 that is collected to below, be deposited on gradually bottom land, can regularly clear up and reclaim.The utility model device has effectively been avoided the loss of the precious metals such as gold and silver, does not also cause environmental pollution simultaneously, has application value.
It should be noted last that: above-described embodiment is only illustrative rather than definitive thereof the technical solution of the utility model; any the utility model is carried out be equal to modification or local replacement of replacing and not departing from the utility model spirit and scope, within it all should be encompassed in the scope of the utility model claim protection.
Claims (2)
