Abstract
The utility model provides an arsenic metal reforming furnace, relating to the field of production technologies of high-purity arsenic. A heating layer is arranged outside a recrystallized silicon carbide reforming pipe. One end of the recrystallized silicon carbide reforming pipe is connected with a feeding pipe via a flange, while the other end of the recrystallized silicon carbide reforming pipe is connected with an aluminum storage tank via a recrystallized silicon carbide connecting pipe. In the utility model, the recrystallized silicon carbide pipe is used as the reforming pipe and also used as a connecting piece for connecting the aluminum storage tank; and the utility model has the advantages of high purity, corrosion resistance, no chemical reaction to the products produced in the production process of high-purity arsenic and long-term availability as well as good thermal conductivity and even thermal field, thus bringing a very large allowance to temperature control in the production process. Meanwhile, the arsenic metal reforming furnace can be conveniently machined into various required shapes to make equipment accessories easily connected and facilitate to increase production capacity and reforming efficiency. The aluminum storage tank, as a loader for products, can effectively prevent secondary pollution after reforming because aluminum has a good resistance to corrosion, and is also easy for processing and low in price.
Description
Technical field
The utility model relates to the high purity arsenic production technical field.
Background technology
The various methods of purification of metallic arsenic all exist one metallic arsenic is converted into certain compound, utilize the physics of this kind compound or the process that the chemical property difference is carried out separating impurity then.Adopting quartz glass is done conversion tube and is used titanium alloy to do product carrier simultaneously before in the high purity arsenic purifying technique, is used for air-isolation and carry reaction medium.Because in this technological process, corrosion reaction is taking place more than 850 ℃ in reaction medium and silica tube, causes the main component SiO of silica tube
2In oxygen replaced by arsenic, silica tube is corroded very soon and appears, and cause medium to reveal, and medium arsenic wherein is oxidized, not only causes the technological process failure, also produces deleterious arsenic oxide arsenoxide, brings pressure for environmental protection and safety in production, has improved cost.Product after titanium alloy and the conversion has minor response in addition, scabs on inwall, is difficult to clean and cause secondary pollution.Because the quartz transition pipe is difficult to make flange, makes flange and also be difficult to be connected with equipment appurtenance because of hard fragility.These problems are a great problems of production process.
Summary of the invention
The utility model purpose is to design a kind of prevent to transform back secondary pollution, metallic arsenic converter durable, that be beneficial to the raising transformation efficiency.
The utility model comprises the re-crystallized silicon carbide conversion tube, outside described re-crystallized silicon carbide conversion tube, zone of heating is set, end at described re-crystallized silicon carbide conversion tube connects feed-pipe by flange, connects the aluminium storage tank at the other end of described re-crystallized silicon carbide conversion tube by the re-crystallized silicon carbide pipe connecting.
The utility model with the re-crystallized silicon carbide pipe as conversion tube, with the web member of re-crystallized silicon carbide pipe as connection aluminium storage tank, have purity height, process product react with corrosion-resistant, that do not produce with high purity arsenic, can life-time service characteristics, and have that heat conduction is good, the thermal field advantage of uniform concurrently, bring very big allowance for the temperature control of production process, simultaneously because it can be processed into the various shapes that need easily, make the equipment appurtenance ease of connection, be beneficial to the increasing turnout, improve transformation efficiency.The aluminium storage tank, does not react with product because the corrosion resistance of aluminium is good as the loader of product, can effectively prevent to transform the back secondary pollution, is easy to processing, low price.
In addition,, improve heat retaining property, also thermal insulation layer can be set outside zone of heating for conserve energy.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is provided with the zone of heating of being made up of nichrome wire 2 outside re-crystallized silicon carbide conversion tube 1, thermal insulation layer 7 is set outside zone of heating 2.One end of crystalline silicon carbide conversion tube 1 connects feed-pipe 6 by flange 5, and the other end connects aluminium storage tank 4 by re-crystallized silicon carbide pipe connecting 3.
Claims (2)
1. metallic arsenic converter, it is characterized in that comprising the re-crystallized silicon carbide conversion tube, outside described re-crystallized silicon carbide conversion tube, zone of heating is set, end at described re-crystallized silicon carbide conversion tube connects feed-pipe by flange, connects the aluminium storage tank at the other end of described re-crystallized silicon carbide conversion tube by the re-crystallized silicon carbide pipe connecting.
