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 ...
