Mixed gas ignition diffusing device

Abstract

The invention discloses a mixed gas ignition diffusing device. The mixed gas ignition diffusing device comprises an outer spinning disk, an inner spinning disk, high-altitude igniters and fire-leadingburners; the inner spinning disk is arranged at the top end of an inner spinning gas connection pipe, gas (1) needing to be diffused is introduced into the inner spinning disk through the inner spinning gas connection pipe, the outer spinning disk is arranged on the periphery of the inner spinning disk in a sleeving mode and fixed to the outer wall of the inner spinning gas connection pipe through a torch head bottom sleeve, and gas (2) needing to be diffused is introduced into the position between the outer wall of the inner spinning disk and the inner wall of the outer spinning disk throughthe torch head bottom sleeve; the fire-leading burners are arranged on the periphery of the top of the outer spinning disk, fire-leading nozzles and ignition nozzles are arranged in the fire-leadingburners, ignition gas is introduced into the ignition nozzles through ignition gas branch pipes, and ignition gas is introduced into the fire-leading nozzles through fire-leading gas branch pipes; andthe high-altitude igniters are used for igniting the ignition nozzles. The mixed gas ignition diffusing device can meet the diffusing requirements of different kinds of gas and has the advantages ofbeing low in investment cost, long in service life, low in operation noise, safe, reliable and the like.

Description

technical field [0001] This patent belongs to the field of gas ignition and diffusion equipment, and relates to an ignition and diffusion equipment, in particular to a mixed gas ignition and diffusion device. Background technique [0002] At present, in the gas ignition and diffusion process of metallurgical enterprises, different types of gas need to be ignited and diffused through their own torch heads. Considering safety factors, the torch heads for gas ignition and diffusion are generally set on towers with a height of 40-50m. [0003] If two or more types of gas are involved in the ignition and combustion, and there is a large difference in the diffusion flow rate of different types of gas or generally low, but still follow the traditional design habits, it will often result in poor stability of the diffusion tower , The effect of gas ignition and diffusion is not ideal, and tempering or fire-off accidents are prone to occur. [0004] The traditional multi-gas ignition...

AI Technical Summary

Problems solved by technology

[0003] If two or more types of gas are involved in the ignition and combustion, and there is a large difference in the diffusion flow rate of different types of gas or generally low, but still follow the traditional design habits, it will often result in poor stability of the diffusion tower , gas ignition and release combustion effect is not ideal, prone to backfire or fire accidents, etc.

[0004] The traditional multi-gas ignition and diffusion process has disadvantages such as high ignition failure rate, high investment cost, complex tower structure and poor stability, short service life of the torch head, and high operating noise, which seriously affects the normal production of the enterprise and the health of the surrounding people. Personal safety has become a serious obstacle to the development of metallurgical enterprises
