A gas purification device for an enamelled furnace

Abstract

The invention discloses a gas purifying device for an enamelling furnace. A slurry pond, an enamelling furnace pipeline and an absorbing liquid spraying layer are arranged in a reaction kettle; a concentrating gas pipeline and a decomposition device are arranged on the upper part of the reaction kettle; the decomposition device comprises a gas pump, an expansion bag and a high temperature pipeline. Compared with the prior art, the gas purifying device for the enamelling furnace provided by the invention has the advantages that the harmful gas generated by the enamelling furnace and the absorbing slurry sprayed through the spraying layer can be effectively fused with the harmful matters and taken into the slurry pond, the remained gas enters the expansion bag and is collected, and then the gas is quickly released and is subjected to high temperature pyrolysis through a high temperature pipeline, the diluent gas is purified, the slurry absorbing the harmful matters is catalyzed by a catalytic reaction device and then is released, enters the concentrating gas pipeline and is directly ignited, the diluted harmful gas is quickly blown out and heated, the concentrated harmful gas is directly burned due to the combustibility thereof, the combustion-supporting fuels are saved and the treatment for the harmful matters is safer.

Description

technical field [0001] The invention relates to a harmful gas purification device, in particular to an enameled furnace gas purification device, which belongs to the field of purification devices in the cable processing process. Background technique [0002] Old-fashioned enamelled ovens are generally heated by tubular heaters, and the top of the oven is equipped with an exhaust system with a water washing device. The disadvantage is that the oven is very sensitive to the airflow of the factory building, and the condensate often blocks the flue and causes a fire. , and the electric heat loss is large, especially the harmful gas discharged from the oven will deteriorate the working environment and bring great harm to people. Centralized treatment, but there is no corresponding standard and method for the treatment method, resulting in no real effective treatment of the harmful gases emitted. [0003] For example, a gas circulation enamelling furnace with a patent number of 2...

AI Technical Summary

Problems solved by technology

The utility model adopts a catalyst catalytic device, which not only eliminates the blockage of condensate, but also solves the problem of environmental pollution and improves working conditions; adopts high-speed hot air flow, improves heat conduction efficiency, makes the furnace temperature evenly distributed, and greatly improves the enamelled bag production. Speed; make full use of the waste heat of the discharged harmful gas to convert it into effective energy. Although the device collects and heats the discharged harmful gas to a certain extent, the power consumption is relatively large, and the heating and combustion are always carry out, invisibly increasing the cost
