Problems solved by technology

They all have one thing in common: use other high calorific value gas sources as the accompanying combustion gas to ignite the auxiliary burner and then ignite the blast furnace gas, which is neither energy-saving nor environmentally friendly, so an improved technology is urgently needed to solve this problem

Abstract

The invention relates to a novel blast furnace gas diffusion and automatic ignition system which comprises a blast furnace gas main pipe network, wherein the blast furnace gas main pipe network is communicated with a storage tank of a gas distributor, the gas distributor also comprises three groups of gas valves, the three groups of gas valves are respectively connected with three high-altitude auxiliary combustors, the high-altitude assisted combustors are fixed on the upper part of a main combustor through a fixed support, the top of the main combustor is connected with a fire detecting device, the fire detecting device is connected with a blast furnace gas diffusion management system, the bottom of the main combustor is connected with a diffusion pipe, the diffusion pipe is connected with the blast furnace gas main pipe network, the blast furnace gas main pipe network is provided with a pneumatic fast switch valve, the pneumatic fast switch valve is connected with the blast furnacegas diffusion management system, the diffusion pipe is also connected with an adjustment valve which is connected with the blast furnace gas diffusion management system, the high-altitude auxiliary combustors are connected with a lift arcing device, and the lift arcing device is connected with the blast furnace gas diffusion management system. The invention has the following advantages: in the working scheme of the full-automatic ignition auxiliary combustion system, the consumption of the system is approximately zero, thus the system is energy-saving and environmentally-friendly.

Description

technical field [0001] The invention relates to a novel blast furnace gas release and automatic ignition system, which does not need other gas sources as accompanying combustion gas, and is energy-saving and environment-friendly. Background technique [0002] Blast furnace gas is a by-product of the ironmaking process, and if it is directly discharged into the atmosphere, it will pollute the environment. In the current metallurgical industry, blast furnace gas is ignited by flames and discharged into the atmosphere to reduce pollution. However, due to the low calorific value of blast furnace gas, it cannot be directly ignited by a high-voltage pulse ignition device. Generally, liquefied petroleum gas, natural gas, and coke oven gas are used as accompanying combustion gases. blast furnace gas. They all have one thing in common: using other high-calorific-value gas sources as the accompanying combustion gas to ignite the accompanying burner and then ignite the blast furnace g...
