Description

Technical Field

[0001] The invention relates to the technical field of graphite felt production, and in particular to a spray liquid purification treatment device and a treatment method for graphite felt production. Background Art

[0002] Graphite felt is a high-performance material, mainly made by graphitizing carbon fiber felt at high temperature, with a carbon content of more than 99%. It has the characteristics of high purity, high temperature resistance, corrosion resistance, non-melting, and good elasticity. It can be folded and cut at will, and can be sewn with graphite yarn. Graphite felt is mainly used as a heat preservation and insulation material for single crystal silicon smelting furnaces. When producing graphite felt, it is necessary to use a high-temperature furnace for heating, which will produce waste gas. In order to avoid direct discharge of waste gas to pollute the environment, a spray liquid purification treatment device is needed to treat the waste gas.

[0003] Most of the existing spray liquid purification treatment devices treat the waste gas during graphite felt production by directly spraying the spray liquid into contact with the waste gas. The spray liquid is mostly discharged directly afterwards, and the spray liquid cannot be recycled. The recycled spray liquid cannot be used for secondary purification of the waste gas. Some harmful substances remaining in the waste gas will still be discharged, and the purification effect of the waste gas is not good. For this reason, we propose a spray liquid purification treatment device and treatment method for graphite felt production. Summary of the invention
