Problems solved by technology

[0002] The sintering machine is heated by mixed gas of high-grade, coke and high-speed, but the gas balance of the steel plant is dynamic, among which, the coke oven gas is often in a surplus state, and the blast furnace gas is in a tense situation, and a large amount of coke oven gas is released, causing energy waste and environmental pollution; The calorific value of the mixed gas used by the machine is not high, and the low calorific value makes the yield of sintered ore low, which is the deficiency of the existing technology

Abstract

The invention provides a distribution combustion gas device of a sintering machine. According to the technical scheme, the distribution combustion gas device comprises a sintering machine inlet pipe communicated with the sintering machine, the sintering machine inlet pipe is communicated with a mixed gas pressure station through a mixed gas pipeline, the sintering machine inlet pipe is further communicated with a coke oven gas distribution combustion pipeline, a gate valve and a coke oven butterfly valve are arranged on the coke oven gas distribution combustion pipeline, and a pressure station outlet butterfly valve and an outlet glasses valve are arranged on the side, close to the mixed gas pressure station, of the mixed gas pipeline. According to the scheme, the gas structure of the sintering machine is provided with two gas sources of coke oven gas and mixed gas through the device, coke oven gas heating can be adopted in a switching mode under the condition of the rich coke oven gas, the rich coke oven gas is consumed, meanwhile, the productivity of the sintering machine is improved, the coke oven gas is automatically adopted in a switching mode when the mixed gas pipeline is repaired, and continuous production of the sintering machine can be guaranteed.

Description

technical field [0001] The invention relates to a sintering machine gas-fired device for digesting excess coke oven gas, reducing the release of coke oven gas and improving the production efficiency of the sintering machine. Background technique [0002] The sintering machine is heated by mixed gas of high-grade, coke and high-speed, but the gas balance of the steel plant is dynamic, among which, the coke oven gas is often in a surplus state, and the blast furnace gas is in a tense situation, and a large amount of coke oven gas is released, causing energy waste and environmental pollution; The calorific value of the mixed gas used by the machine is not high, and the low calorific value leads to a low yield of sintered ore, which is the deficiency of the existing technology. Contents of the invention [0003] The purpose of the present invention is to aim at the deficiencies in the prior art, and to provide a technical solution for a sintering machine with coal gas device. ...
