Abstract
The utility model relates to a kind of hydrogen and oxygen gas mixture spark arrester, comprises plunger booster tank and piston/cylinder, and described piston/cylinder inside is provided with piston, and piston surrounding is equipped with resistance seals cushion rubber.Described plunger booster tank top is provided with mist upper outlet, is provided with hydrogen and oxygen gas mixture import bottom piston/cylinder, and right side is provided with hydrogen and oxygen gas mixture outlet, time delay pipe, and time delay pipe exports, ash-hole.The hydrogen and oxygen gas mixture spark arrester of the utility model design, unique back-fire relief structure, effectively can control flow and the flow direction of gas, controls detonation and occurs; Automatically control by gas pressure the position that piston is set, make it remain on normal place, and without the need to adopting electronic device to control, thus more safe.
Description
Technical field
The invention belongs to back-fire relief explosion-protection equipment technical field, be specifically related to a kind ofly prevent from exploding for gas discharge in mine and chemical industry tail gas CIU and the mist spark arrester that conducts along extraction pipeline of flame blocking that blast produces.
Background technology
Hydrogen and oxygen gas mixture spark arrester is mounted in a kind of safety convenience instrument of the positive pressure side of releasing pipe, when gas drainage pipeline meets accident explosion accident, the shock wave that preventing explodes produces destroys drainage system, and the flame blocking blast generation conducts along extraction pipeline, a kind of Special safety device that Accident prevention expands further, can select the explosion-proof mist spark arrester of different size according to the size of different pipeline diameter.
Spark arrester of the prior art, its structure is comparatively simple, only comprises air inlet pipeline, gas exhaust piping and explosion-proof vent, such spark arrester due to structure simple and crude, poor controllability, Fire resistances is low, there is very large potential safety hazard.
Summary of the invention
The object of the invention is to provide a kind of Fire resistances high, safe and reliable hydrogen and oxygen gas mixture spark arrester.
For achieving the above object, a kind of hydrogen and oxygen gas mixture spark arrester of the present invention's design, comprise plunger booster tank 1 and piston/cylinder 2, described piston/cylinder 2 inside is provided with piston 3, and piston 3 surrounding is equipped with resistance seals cushion rubber 4.
In technique scheme, described plunger booster tank 1 top is provided with mist upper outlet 5, is provided with hydrogen and oxygen gas mixture import 6 bottom piston/cylinder 2, and right side is provided with hydrogen and oxygen gas mixture outlet 7, time delay pipe 8, time delay pipe outlet 9, ash-hole 10.
The hydrogen and oxygen gas mixture spark arrester of the present invention's design, unique back-fire relief structure, effectively can control flow and the flow direction of gas, controls detonation and occurs; Automatically control by gas pressure the position that piston is set, make it remain on normal place, and without the need to adopting electronic device to control, thus more safe.
Accompanying drawing explanation
Fig. 1 is working state structure schematic diagram of the present invention;
Fig. 2 is back-fire relief status architecture schematic diagram of the present invention;
In figure: 1-plunger booster tank; 2-piston/cylinder; 3-piston; 4-resistance seals cushion rubber; 5-mist upper outlet; The import of 6-hydrogen and oxygen gas mixture; 7-hydrogen and oxygen gas mixture exports; 8-time delay pipe; 9-time delay pipe exports; 10-ash-hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail: as shown in Figure 1, during duty, hydrogen and oxygen gas mixture enters mist import 6 by after electrolysis installation output, piston/cylinder 2 is constantly entered along with mist, pressure increase, piston 3 open-close on-off with three-layer sealed resistance cushion rubber 4 is upwards backed down, mist enters piston/cylinder 2, piston/cylinder 2 is discharged via mixed gas outlet 6, through time delay pipe 8, plunger booster tank 1, finally discharge from mist upper outlet 5, send into burner.
During back-fire relief state, because be hydrogen-oxygen mixed combustible gas body, have the possibility of tempering, once tempering, burning gases are from mist upper outlet 5 return piston booster jar 1.Because plunger booster tank 1 is strengthened intentionally when designing, so the detonation of certain equivalent can be produced, pressure in plunger booster tank 1 body can increase suddenly, utilize this pressure piston 3 open-close on-off to be rapidly to down and be pushed into bottom, mist air inlet 6 and mist gas outlet 7 are isolated, close.While closure piston 3 open-close on-off, the flame of plunger booster tank 1 together with time light the mist in time delay pipe 8 fuel gas exit, flame burns the joint portion of mixed gas outlet 7 and piston/cylinder 2 along time delay pipe 8 always.At this moment because time delay canal path is longer, before flame arrives mixed gas outlet 7, piston 3 open-close on-off is closed previously, and fire is blocked, and cannot continue to extend, extinguish, back-fire relief completes.Mist is entered by hydrogen and oxygen gas mixture import 6 again, spark arrester rearming.
The mist spark arrester of the present invention's design, Fire resistances is superior, and security is high, and system reliability is strong.
