Coal mine mash gas incineration torch

Abstract

The invention discloses a coal-mine gas-burning torch which comprises a burner and etc. systems including an insulation layer arranged inside a casing; a regenerative honeycomb ceramics and a bracket thereof which are arranged in the middle of the insulation layer, a proportioning mixer and a multi-head mixed-gas nozzle which are arranged on a lower part of the bracket; an upper sealing cover arranged at the upper end of the casing and a lower sealing cover and a base which are arranged at the lower end of the casing; a pipeline and a main gas supply valve which are connected with the proportioning mixer; a pressure-regulating valve, a flame arrester, a filtering dehydrator, a hydroseal flame arrester, an electronic-control valve and a gas diffusion valve which are sequentially connected; a fan which is arranged inside the base under the casing and connected with the lower part of the proportioning mixer; an electronic ignition system comprising an LPG fuel supply valve, a gas supply valve connected with a gas transferring pipeline and an electronic igniter communicated with the lower part of the burner; a temperature sensor arranged in the regenerative honeycomb ceramics; an air pressure sensor arranged at the back of the fan; a gas concentration sensor, a gas pressure sensor and an electronic-control valve which are arranged in the gas transferring pipeline system and a controller arranged on the lower part of the casing.

Description

1. Technical field [0001] The invention relates to coal mine gas incineration equipment, in particular to a coal mine gas incineration flare. 2. Background technology [0002] The traditional method of gas treatment in coal mining is direct discharge, but this method has the following disadvantages or deficiencies: ①The average concentration of the gas drained is currently lower than 30%, and for the gas with a gas concentration higher than 30%, due to civil Intermittence and discontinuity of utilization methods such as power generation, etc., cause some gas to be directly emptied, polluting the atmospheric environment. ②Because the gas drainage changes with underground coal mining activities, its gas concentration also changes all the time, and the concentration may approach or enter the explosion limit of 5% to 15%. For example, the gas is destroyed by directly igniting the gas at the gas outlet There is a big safety problem in the methane, and the lack of treatment will ...

Problems solved by technology

[0002] The traditional method of gas treatment in coal mining is direct discharge, but this method has the following disadvantages or deficiencies: ①The average concentration of the gas drained is currently lower than 30%, and for the gas with a gas concentration higher than 30%, due to civil Intermittent and discontinuous utilization means such as power generation or power generation, causing some gas to be directly emptied, polluting the atmospheric environment

②Because the gas drainage changes with underground coal mining activities, its gas concentration also changes all the time, and the concentration may approach or enter the explosion limit of 5% to 15%. If the gas is destroyed by directly igniting the gas at the gas outlet The methane in the gas has great safety problems, and the lack of treatment will cause equipment, personal and property losses
