Electric de-dusting purifying device for phosphorus-making furnace gas

Abstract

The invention provides an electric de-dusting purifying device for phosphorus-making furnace gas and relates to the electric de-dusting purifying device for furnace gas from a process of preparing yellow phosphorus by taking phosphate ore as raw materials and particularly from a process of preparing the phosphorus by adopting a multi-electrode phosphorus-making electric furnace. The electric de-dusting purifying device is characterized by structurally comprising an electric de-duster and a heating pre-treating device for the phosphorus-making furnace gas, wherein the heating pre-treating device is located on the lower part of the electric de-duster and is integrally communicated with a shell of the electric de-duster. The electric de-dusting purifying device provided by the invention is used for fully gasifying the dust-containing phosphorus furnace gas in a state of condensation under the effect of quickly heating, so that the thorough gas-solid separation is achieved; the problem that the phosphorus gas condensation and the dust are removed together after the phosphorus gas condensation is attached to and packaged with the dust is avoided; and meanwhile, the large grain dust in the phosphorus furnace gas is removed under the action of gravity settling, so that the phosphorus furnace gas can attain the condition of efficient de-dusting work of the electric de-duster; the production process flow is simplified; the labor intensity of operators is reduced; the once phosphorus yield is increased; the output of phosphorus mud and the output of waste water are reduced; the cost of treating the phosphorus mud and the waste water is correspondingly reduced; and the economic benefit and the environmental protection benefit are significant.

AI Technical Summary

Benefits of technology

This patented technology describes an improved electrical dedust cleanup system that uses highly effective heating functions to rapidly warm up the exhaust gases from a phosphonium making plant without causing problems such as clumpings during storage and transportations. It achieves these technical results through its use of advanced materials like ceramics, metal plates, conductive fibers, insulators, etc., along with various techniques used to prevent unwanted deposits on surfaces inside the machine's chamber walls. Additionally, there may be other devices added downstream of the treatment unit to further enhance performance. Overall, this innovative design improves overall operational efficacy while reducing costs associated with traditional methods.

Problems solved by technology

This patented describes an improved technique called multiple-pole electrical arc furnace for producing phosphorous without generating harmful exhaust emissions during the manufacturing process. However, conventional methods have limitations when applying these techniques to the production line itself. These include difficulties associated with cleanup operations, excessive power consumption, difficulty in handling heavy metals, and potential safety hazards caused by residual hydrocarbon combustion products generated during coolant circulations within the system.
