Embodiment

[0013] The irregular filler 9 of the present invention is the cobblestone that is convenient to collect. The shape of the cobblestone is smooth, and the gap 8 naturally formed after the interlayer 4 is stacked is fine and irregular. In addition, the cobblestone has good heat absorption performance, which strengthens the flame retardant effect.

[0014] Before operation, place pebbles of different diameters in the interlayer 4 respectively, and the order of placement is: the diameter of the cobblestones in several interlayers 4 gradually becomes smaller from bottom to top, which can better absorb heat and flame-retardant. During operation, the gas inlet pipe 5 introduces gas with a certain pressure, and the gas overflows from the gaps 8 formed by stacking cobblestones in several interlayers 4, and the gas that overflows is introduced into the work area by the gas outlet pipe 7 for use. When the gas delivery device fails and the operator does not take blocking measures, temperin...

Abstract

The invention relates to an automatic fuel gas tempering blocking device. The automatic fuel gas tempering blocking device comprises a base and a barrel body, wherein the barrel body is fixed on the base; a seal cover and a gas exhaust pipe are arranged above the barrel body; a gas intake pipe is arranged below the barrel body; a plurality of baffle layers are uniformly distributed between the parts of the gas intake pipe and the gas exhaust pipe in the barrel body, and are respectively provided with irregular fillers; clearances are formed among the irregular fillers. The automatic fuel gas tempering blocking device provided by the invention is simple in structure and convenient to operate, and blocks fuel gas tempering automatically under accidental conditions so as to eradicate the safety hazard.

Description

technical field [0001] The invention relates to a gas safety protection device, in particular to a gas backfire automatic blocking device. Background technique [0002] Tempering after failure of industrial gas devices and agricultural biogas digesters often brings immeasurable losses to people's lives and property, which is an urgent problem for technicians to solve. Therefore, it is necessary to efficiently quench the tempering after the tempering is caused by the failure of the gas device or the agricultural biogas digester, so as to eliminate the hidden danger of accidents. Existing gas tempering is realized through manual monitoring. When the operator finds the tempering, he closes the gas valve to realize the tempering blocking, which often causes major safety production accidents due to human negligence. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic gas backfire blocking device with simple ...
