Abstract

The invention discloses an environment-friendly magnesia-carbon brick heat treatment kiln and a treatment method thereof, comprising a chimney, a combustion-supporting fan, a heat exchanger, a combustion-supporting air pipeline, a harmful gas volatilization pipeline, a combustible gas pipeline, a combustion chamber, a plurality of magnesia-carbon bricks and Heat treatment kiln body; a plurality of magnesia carbon bricks are arranged in the heat treatment kiln body at intervals; the combustion-supporting fan is connected to an inlet end of the heat exchanger, and an output end of the heat exchanger is connected to the inlet end of the combustion-supporting air pipe, and the flame-retardant air pipe The outlet port is connected to one inlet port of the combustion chamber; the combustible gas pipeline is connected to the other inlet port of the combustion chamber, and the outlet port of the combustion chamber is connected to the heat treatment kiln body through a pipeline and connected to the other inlet port of the heat exchanger. The heat treatment kiln The harmful gas in the body is connected to the combustion chamber through the harmful gas volatilization pipe, and the other outlet port of the heat exchanger is connected with the chimney. The invention can reduce environmental pollution, reduce energy consumption and improve thermal efficiency.

Description

technical field [0001] The invention relates to a refractory material, in particular to an environment-friendly magnesia-carbon brick heat treatment kiln and a treatment method thereof. Background technique [0002] At present, magnesia-carbon brick heat treatment furnaces mostly use electric heating or coal heating, and process magnesia-carbon bricks at 200-250 °C. During the heat treatment process, the phenolic resin binder used in the magnesia carbon brick will volatilize a large amount of harmful gases such as polycyclic aromatic hydrocarbons such as benzene and phenol (accounting for about 1.2-1.5% of the total brick weight). These gases are directly discharged into the air pollution environment without harmless treatment. At the same time, the discharged gases have high calorific value and are not recycled, resulting in energy waste. Contents of the invention [0003] The purpose of the present invention is to provide an environment-friendly magnesia-carbon bric...
