Description

Technical Field

[0001] The invention belongs to the field of elemental arsenic production systems, and in particular relates to an elemental arsenic production system. Background Art

[0002] Arsenic trioxide is a non-metallic element that plays an important role in alloy manufacturing, pesticides and insecticides, medicines, glass manufacturing, semiconductor and laser technology. Arsenic trioxide is often produced as waste gas in metal smelting and other processes. In order to increase its utilization rate, arsenic trioxide can be used to reduce elemental arsenic. During the reduction, arsenic trioxide needs to be sublimated, so a sublimation furnace is needed. During the reduction and sublimation process, arsenic trioxide is a highly toxic compound. Its toxicity mainly comes from its chemical structure and the reaction in the human body. When arsenic trioxide sublimates, it decomposes to produce arsenic and other compounds. These products will form highly toxic gases under certain conditions, especially when encountering high heat. The gas produced by the sublimation of diarsenic is highly toxic, so the gas discharged from the sublimation furnace needs to be collected and processed by a collecting device. When the existing technology is used, the traditional production system needs to manually enter the production environment to change furnaces, add materials, etc. during the production of elemental arsenic. Although protective clothing can be worn, it is impossible to be completely immune to harm. The workers are still more or less affected by harmful gases, especially when there are omissions in protection, dangerous accidents are prone to occur, and the risk is high. At the same time, frequent entry and exit during the production process also requires frequent purification and wearing of protective clothing, which is inconvenient. In addition, when the existing technology is used, the production system has a low degree of automation, continuous production requires a high labor force, and the labor intensity of the workers is high, which is not convenient for continuous production. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] In order to overcome the shortcomings of the existing technology, a single arsenic production system is proposed to solve the problem that when the existing technology is used, the traditional production system needs to manually enter the production environment to perform operations such as furnace replacement and material addition during the single arsenic production process. Although protective clothing can be worn, it is impossible to be completely immune to harm. The staff will still be more or less affected by harmful gases. Especially when the protection is neglected, dangerous accidents are prone to occur, which is highly dangerous. At the same time, frequent entry and exit during the production process also requires frequent purification and wearing of protective clothing, which is relatively inconvenient.

[0037] In order to solve the problem that when the existing technology is used, the traditional production system needs to manually enter the production environment to perform operations such as furnace replacement and material addition during the production of elemental arsenic. Although protective clothing can be worn, it is impossible to be completely immune to harm. The workers are still more or less affected by harmful gases. Especially when protection is neglected, dangerous accidents are prone to occur, which is very dangerous. At the same time, frequent entry and exit during the production process also requires frequent purification and wearing of protective clothing, which is relatively inconvenient. In addition, when the existing technology is used, the production system has a low degree of automation, continuous production requires a high labor force, the labor intensity of the workers is high, and it is not convenient for continuous production. The production area is divided into an automatic area and a manual area, and the automatic area is equipped with automatic feeding, sublimation, cooling preparation, lifting and conveying equipment.

The furnace body after material collection can be automatically transported back to the placement place and automatically lifted and placed by the lifting equipment, and can be automatically prepared for feeding through the feeding equipment. The high degree of automation can greatly reduce manual contact during production and reduce production risks, thereby reducing the inconvenience of frequent entry and exit purification and wearing protective clothing.
