Anti-oxyhydrogen flame tempering dry optical control device

Abstract

The invention discloses an anti-oxyhydrogen flame tempering dry optical control device, which aims to overcome the defect in conventional similar technology that a tempering oxyhydrogen flame and delivered oxyhydrogen cannot be completely blocked to cause combustion and heating in a flame arrestor, reduce the fireproof performance of the flame arrestor and make the oxyhydrogen flame cross the dryflame arrestor to further cause high risk, high cost in the replacement of the flame arrestor and influence on the popularization of the oxyhydrogen as a fuel gas. The key points of the technical scheme are that: the anti-oxyhydrogen flame tempering dry optical control device comprises the dry flame arrestor, an electromagnetic valve and a sensor for controlling the closing of the electromagneticvalve, wherein the flame arrestor and the electromagnetic valve are connected in series to a gas supply pipeline arranged between a combustor and an oxyhydrogen generation device; the flame arrestor is positioned behind the electromagnetic valve; and the sensor is arranged behind the flame arrestor. The anti-oxyhydrogen flame tempering dry optical control device is characterized in that: the oxyhydrogen supply pipeline behind the flame arrestor is provided with a non-light tight part for monitoring tempering flashing in the oxyhydrogen supply pipeline; and an electronic photosensitive device is arranged outside the non-light tight part, and is electrically connected with the electromagnetic valve through a circuit.

Description

technical field [0001] The invention relates to an accessory or component of a combustion appliance using hydrogen-oxygen mixture as fuel, in particular to a hydrogen-oxygen flame flashback that prevents combustion or even explosion in the hydrogen-oxygen mixture air delivery channel when the hydrogen-oxygen flame generates backflow Dry fire arrester. Background technique [0002] Using the hydrogen-oxygen mixture produced by water electrolysis as fuel gas, as an energy source with the characteristics of cheapness, environmental protection, high efficiency, and energy saving, can replace traditional fuel gases such as acetylene, propane, carbon trigas, and liquefied petroleum gas. It is a technology that has emerged in recent years The project has been widely used in the fields of glass product production, tempered glass production, ceramic product production, welding and cutting industry, automobile energy and household gas. The hydrogen-oxygen mixed gas generating device ...

Problems solved by technology

[0006] In order to overcome the problem that the existing hydrogen-oxygen flame dry-type anti-temper device cannot completely block the tempering hydrogen-oxygen flame and the transported hydrogen-oxygen mixture, which will cause combustion and heat in the dry-type anti-temper device and damage the flame-retardant performance of the dry-type anti-temper device , when tempering again, the hydrogen-oxygen flame may pass over the dry-type anti-temper device, which is dangerous, and the cost of replacing the dry-type anti-temper device is relatively high, which affects the popularity and promotion of hydrogen-oxygen mixture as fuel gas. The purpose of the present invention It is to provide an improved hydrogen-oxygen flame tempering dry flame arresting light control device, which can overcome the defects of the prior art
