AI Technical Summary

Technical Problem

How to achieve stable operation of the same coil module adapted to plasma torches under different parameters without changing the product structure of the arc plasma torch, especially for high-power plasma torches greater than 2MW, and improve electrode life.

Method used

A modular coil magnetic field method is adopted, which involves preparing several coil magnetic field modules with progressively increasing diameters and embedding matching annular grooves between the inner wall and outer shell of the plasma torch. The modules are fixed by a mounting bracket and cooled by a cooling water channel, thereby achieving flexible adjustment and stable operation of the coil magnetic field.

Benefits of technology

It achieves stable operation under different parameters without changing the plasma torch structure, extends electrode life to over 2000 hours, and improves electrical conversion efficiency to 80%, making it suitable for treating solid waste incineration residues with a capacity of over 10 t/d.

Abstract

本发明公开了一种模块化等离子体炬线圈磁场设计方法,包括以下步骤:(1)制备数个直径依次递增的线圈磁场模块;(2)根据线圈磁场模块的数量,在等离子体炬的内壁和外壳之间靠其前电极侧开设有圆环形凹槽;(3)根据等离子体炬的运行参数选择线圈磁场模块的插入数量,将线圈磁场模块依次套接后,在其顶面和底面分别设有模块固定架;(4)将线圈磁场模块插入圆环形凹槽内,并通过模块固定架进行支撑固定,进而形成磁场;(5)在等离子体炬内部开设有冷却水通道,进而利用电极冷却水回水对线圈磁场模块进行冷却。本发明采用线圈磁场模块化设计,可在不改变等离子体炬产品结构的前提下,实现等离子体炬在不同参数下的稳定运行。
