Embodiment 1

[0032] Figure 1-Figure 2 Disclosed in is a hydrogen flame arrester, including a flame arrester sleeve 1, one end of the flame arrester sleeve 1 is an air inlet joint 101 connected to an intake pipe 2, and the other end is an outlet joint 103 connected to an air outlet pipe 3, and the flame arrester sleeve A fire arrester 4 is installed inside the tube 1; the fire arrester 4 is a large number of thin metal wires, which are filled in the flame arrester casing 1 in a regular and orderly manner along the radial direction, forming a large number of regularly arranged The elongated gas guide micropore 401; the end of the flame arrester 4 is flush with the end face of the gas outlet joint 103 (see Figure 3-Figure 5 ). The air outlet pipe 3 is a non-metallic pipe.

Embodiment 2

[0034] A hydrogen flame arrester, the structure of the flame arrester is basically the same as that of Embodiment 1, the difference is that a radiator 5 is provided outside the flame arrester casing 1 .

[0035] The specific structure of the hydrogen flame arrester described in the second embodiment is as follows:

[0036] A hydrogen flame arrester, comprising a flame arrester sleeve 1, one end of the flame arrester sleeve 1 is an air inlet joint 101 connected to an intake pipe 2, and the other end is an outlet joint 103 connected to an air outlet pipe 3, and the flame arrester sleeve 1 is installed There is a fire arrester 4; the fire arrester 4 is a large number of fine metal wires, which are filled in the flame arrester casing 1 in a regular and orderly manner along the radial direction, forming a large number of regularly arranged elongated The air guide microhole 401; the end of the fire arrester 4 is flush with the end face of the air outlet joint 103; the outlet pipe 3 ...

Embodiment 3

[0038] A hydrogen flame arrester, the structure of the flame arrester is basically the same as the second embodiment, the difference is that: the flame arrester casing 1 is also equipped with a temperature sensor 6, and the air inlet pipe 2 is also installed with a The detection data of the temperature sensor automatically cuts off the solenoid valve 7 of the air source (for the electrical schematic diagram, see Figure 9 ).

[0039] The specific structure of the hydrogen flame arrester described in the third embodiment is as follows:

[0040] A hydrogen flame arrester, comprising a flame arrester sleeve 1, one end of the flame arrester sleeve 1 is an air inlet joint 101 connected to an intake pipe 2, and the other end is an outlet joint 103 connected to an air outlet pipe 3, and the flame arrester sleeve 1 is installed There is a fire arrester 4; the fire arrester 4 is a large number of fine metal wires, which are filled in the flame arrester casing 1 in a regular and orderl...

Abstract

The invention relates to a device for preventing backfire, and in particular relates to a hydrogen gas fire arrester. The hydrogen gas fire arrester comprises a fire arrester sleeve, wherein one end of the fire arrester sleeve is an air inlet connector connected with an air inlet pipe, and the other end of the fire arrester sleeve is an air outlet connector connected with an air outlet pipe; a fire-retardant body is arranged in the fire arrester sleeve; a great deal of long and thin air guide micropores which are regularly arranged are formed in the fire-retardant body; the tail end of the fire-retardant body is flushed with the end surface of the air outlet connector; the air outlet pipe is a non-metallic pipe; a radiator is also arranged outside the fire arrester sleeve; the fire arrester sleeve is also externally provided with a temperature sensor; the air inlet pipe is provided with an electromagnetic valve. After the hydrogen gas fire arrester is adopted, effective and reliable fire retardance is realized, and the phenomenon that the fire arrester is burnt out or has failure since the temperature of a pipeline is increased drastically can be avoided; the hydrogen gas fire arrester is simple in structure, low in cost and easy to popularize and apply.

Description

technical field [0001] The invention relates to a device for preventing flashback, in particular to a hydrogen flame arrester. Background technique [0002] When a hydrogen-oxygen generator such as a hydrogen-oxygen cutting machine has a tempering failure, it is usually due to the mixture of hydrogen and oxygen in the output gas. When the flow rate of the mixed gas is lower than the flame combustion speed, the flame will live inside the machine; the current flame arrester It usually includes a flame arrester and a gas source cut-off mechanism. Because the combustion speed of hydrogen is very fast, the internal mechanism of the ordinary mechanical flame arrester has no time to cut off the gas source, or cannot be cut off reliably. Cause the flame arrester to fail, and the oxyhydrogen flame will run into the next component. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydrogen flame arrester to solve the dis...
