Heat accumulating type organic waste gas incinerator and running method thereof

Abstract

The invention belongs to the technical fields of environmental protection and air pollution control, and relates to a regenerative organic waste gas incinerator and an operation method thereof, which are used for treating organic waste gas containing low-concentration volatile organic compounds with high efficiency and low cost. The innovation of the present invention lies in: a regenerative organic waste gas incinerator and its operation method, in which four identical regenerators are arranged in the incinerator body; each regenerator is connected to the organic waste gas through an air intake control valve Exhaust gas main pipe connection; each regenerator is connected to the flue gas main pipe through an exhaust control valve; each regenerator is connected to the atmospheric environment through a purge control valve; each valve operates in sequence according to a specific control sequence , to achieve low-cost and high-efficiency treatment of organic waste gas, while ensuring the continuity of organic waste gas and ensuring that there is no direct discharge of untreated organic waste gas. The purging system has no additional equipment and pipelines, and the system is simple.

Description

technical field [0001] The invention belongs to the technical fields of environmental protection and air pollution control, and relates to a regenerative organic waste gas incinerator and an operation method thereof, which are used for treating organic waste gas containing low-concentration volatile organic compounds with high efficiency and low cost. Background technique [0002] Currently used regenerative organic waste gas incinerators have several structural forms, including two regenerators, three regenerators and multiple regenerators with rotary reversing. The incinerator with two regenerators has the problems of direct discharge of waste gas during reversing, which causes a decrease in the destruction removal rate, and a sudden drop in the flow rate of the treatment system during reversing. The three-regenerator incinerator increases the purge system to improve the damage removal rate during the reversing, but there is still the problem of a sudden drop in the flow r...

AI Technical Summary

Problems solved by technology

The incinerator with two regenerators has the problem that the waste gas is directly discharged when the direction is reversed, which causes the damage removal rate to decrease, and the flow rate of the treatment system drops sharply when the direction is reversed.

The three-regenerator incinerator adds a purge system to improve the damage removal rate when the direction is reversed, but there is still the problem of a sudden drop in the flow rate of the treatment system when the direction is reversed.

The multi-regenerator rotary reversing incinerator solves the problem of low damage removal rate and sudden drop in flow rate of the treatment system during reversing, but it also brings high manufacturing cost, high failure rate and yearly increase in valve leakage of the rotary reversing valve, resulting in damage removal rate reduction etc.
