The preparation of metallic arsenic use carbon reduction method, using 98%-99% high-grade arsenic trioxide as raw material, using distillation,
Reduction, cooling technique produce the α metallic arsenic of 99% grade.The α metallic arsenic of 99% grade be production copper, lead, antimony hard alloy,
The raw material of glass, medicine, pigment, pesticide etc..
There are three types of different types for metallic arsenic: α type, β type and γ type.Under the conditions of different cooling temperatures, gaseous state arsenic will be converted
At different types of solid-state arsenic, crystallisation by cooling temperature parameter is detailed in following table:
| Serial number | Crystallisation by cooling temperature (DEG C) | Solid-state arsenic type |
| 1 | 500-400 | α metallic arsenic |
| 2 | 400-200 | β metallic arsenic |
| 3 | < 200 | γ metallic arsenic |
By the arsenic trioxide of 98%~99% grade in raw material storage device 5 by screw(-type) feeder at the top of retort 1
It is added in furnace, material passes through 400 DEG C~700 DEG C continuous high temperature distillations, low boiling point semimetal arsenic trioxide quilt in retort 1
Heating sublimation becomes arsenic trioxide steam and high-boiling-point impurity (copper oxide, tin oxide, lead oxide, antimony oxide etc.) melting point
From.Arsenic trioxide becomes gaseous state, and pressure increases in retort 1, gaseous pressure about 1kg/cm2, retort 1 and the first cooling are defeated
The pressure difference of device 3 is sent, so that gaseous state arsenic trioxide is exported from 1 top of retort, is imported into 2 lower part of reduction furnace.
Arsenic trioxide and high boiling copper, tin and the melting agent that retort 1 is not completely distilled off are fused into low-melting-point liquid
Clinker enters the second cooling conveying device 4 from furnace bottom outflow, and the second cooling conveying device 4 is cooling using indirect water-cooling mode, cold
But the clinker after returns to raw material storage device 5 and reuses as raw material.
Reducing medium active carbon particle enters at the top of nitrogen-filled seal tank a from the gravity flow of 6 bottom of reducing medium storage device, warp
The nitrogen-filled seal bottom tank a flows into sealed screw(-type) feeder, is admitted to top fixed carbon bed in reduction furnace 2.Active carbon is solid
Slowly mobile from top to down in fixed bed, gaseous state arsenic trioxide is inversely contacted with active carbon particle from bottom to top, in reduction furnace 2
Under interior 600 DEG C~800 DEG C hot conditions, arsenic trioxide is reduced into gaseous metal arsenic, reacts as follows:
As2O3+ 3C=2As+3CO
Wherein, 320 DEG C of arsenic trioxide sublimation temperature or so, 600 DEG C of metallic arsenic sublimation temperature.Reduction furnace 2 and first cold
But the non-oxide atmosphere in conveying device 3 can be provided by being filled with nitrogen, the subsequent side that carbon monoxide is generated by excess activity charcoal
Formula maintains.
A part of active carbon is aoxidized by gaseous state arsenic trioxide and generates carbon monoxide, another part active carbon in reduction furnace 2
Absorption association in the higher boiling copper oxide of arsenic trioxide, tin oxide, lead oxide, antimony oxide beavy metal impurity and inactivate, inactivate
Active carbon be continuously discharged from 2 bottom of reduction furnace by discharge device.
Gaseous materials containing target product gaseous metal arsenic and carbon monoxide are introduced from the warm pipeline in 2 top of reduction furnace
The top of first cooling conveying device 3, gaseous state arsenic cool down in the first cooling conveying device 3 through air indirectly, and control first is cold
But 3 temperature range of conveying device: 400 DEG C~500 DEG C, arsenic steam is made to be condensed into the sheet α metallic arsenic of 99% grade.First is cooling
Sheet α metallic arsenic in conveying device 3 is discharged into finished product storage device 7 from 3 bottom of the first cooling conveying device, through pack, metering,
Bagging and packaging is at packed finished product.Condensed product tail gas is through the waste heat recycling of emission-control equipment 8, bag-type dusting, wet process alkali
Wash qualified discharge after (NaOH), washing process.It is recycled after the sewage treatment of wet-treating tail gas or qualified discharge, precipitating is dirty
The dust that mud and sack cleaner are accepted returns to raw material storage device 5 and uses as raw material.
Because using high temperature distillation, the separating effect of arsenic and copper, tin is improved, slag is low containing arsenic, and the rate of recovery improves 10%.And
Realize that the continuous coo1ing of metallic arsenic can reduce energy consumption 50% to realize continuous production by the first cooling conveying device, electricity
Consumption is reduced to 4000 KWhs/ton by 8000 KWhs/ton.Also, it because using automatic continuous production, operates, mentions at the scene without personnel
High production security.
Metal continuous still provided by the utility model also original system is able to achieve the continuous production of metal, improves metal and returns
Yield, reduces energy consumption, and highly effective and safe reduces production cost.And workshop occupied area is small, reduces investment outlay.Since low energy consumption, metal
The rate of recovery is high, and production cost substantially reduces, easy to promote and utilize.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
