An inert gas generator

Abstract

The invention discloses an inert gas generator, comprising a support seat, a primary heating region, a secondary heating region and an inert gas flue, which are orderly connected from bottom to top. Burning powder and a gas and carbon monoxide gas in a protected airtight space in a mined-out area are utilized, the furnace temperature is automatically adjusted and controlled through a controller, oxidation reaction of a burning medium and oxygen in air pumped into a hearth is ensured, so as to generate a carbon dioxide gas and other inert gases, and then the carbon dioxide gas and other inert gases are fed to the protected airtight space in the mined-out area. The quantity demanded on a burning powder source is reduced to a certain extent by collection of the gas and carbon monoxide in the mined-out area and burning utilization, so that a waste utilizing role is played. The intrinsic safety of the protected airtight space in the mined-out area is ensured by an active protection mode. In addition, an internal sealing cycle is formed on the inert gas generator and the protected airtight space in the mined-out area in structure, 'zero' pollution to the environment is achieved, energy conservation and emission reduction are facilitated, and the inert gas generator is an energy-saving and environment-friendly product.

Description

Technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to an inert gas generator applied to an active safety protection system for a protected enclosed space in a coal mine goaf. Background technique [0002] Regardless of fuel inert gas fire-fighting technology, liquid carbon dioxide fire-fighting technology, etc., up to now, the products formed by the specific device or system design of inert gas technology at home and abroad, without exception, are open in structural design. While preventing and extinguishing fires, because the closed structure design is not adopted in the structure, a large part of the combustible gas or inert gas in the protected space will be directly discharged into the air, forming secondary pollution to the surrounding environment of the protected object. Summary of the invention [0003] The purpose of the present invention is to provide an inert gas generator capable of burning the gas and carbon mo...

Problems solved by technology

[0002] Regardless of fuel oil inert gas fire prevention technology, liquid carbon dioxide fire prevention technology, etc., so far, the products formed by the specific device or system design of inert gas technology at home and abroad are all open in structure design. At the same time of fire prevention and extinguishing, because the structure does not adopt a closed structure design, a large part of the combustible gas or inert gas in the protected space will be directly discharged into the air, forming a secondary pollution to the surrounding environment of the protected object
