Description
One, technical field
The utility model belongs to the datonation-inhibition technical field of coal mine, and in particular to one kind is suitable for coal mine fire-fighting, the datonation-inhibition system of gas
The pipe used in mine carbon dioxide explosion suppressor of system.
Two, background technique
With the development of science and technology with the propulsion of process of industrialization, the exploitation of mechanization obtained increasingly in Modern coal mines
It is extensive to promote and apply, and trend develops towards high-power and automation direction.By feat of a large amount of modernization winning apparatus
Application, the mankind not only greatly improve production efficiency, but also just constantly increasingly complex towards deeper coal seam and geological environment
Seam mining operation, the coal mining of big intensity and deep difficulty necessarily brings the new problem in safety in production, especially for
Prevention and treatment threatens more prominent for the gas of safety of coal mines.Gas density explosion limit range is 5%~16%, and low concentration gas is in benefit
With and discharge process in all there is serious security risk.To solve the above-mentioned problems, people are using various means to gas pipe
Road progress is datonation-inhibition, which is the key equipment in gas drainage system, it is desirable that can quickly, reliably be opened, it is ensured that suppression
Quick-fried system works at crucial moment, the generation for inhibiting explosive flame is played, to protect the personal safety of underground work personnel
And property safety.
Currently, datonation-inhibition technology used by the datonation-inhibition fire prevention system of coal mine gas mainly has dry powder suppression
The modes such as quick-fried, mechanically datonation-inhibition, dry powder is there are datonation-inhibition rear cleaning difficulty, and mechanical datonation-inhibition leakproofness reliability is not
Height, the response time is slow, and the especially mechanical datonation-inhibition response time reaches 90ms.
Carbon-dioxide fire engine essentially consists in asphyxia, followed by cooling.In fire extinguishing procedure, dioxy
Change carbon to release from storage gas cylinder, pressure declines suddenly, so that carbon dioxide is turned by liquid
Become gaseous state, be distributed in flame periphery, discharge the oxygen content in air, oxygen content reduction can make
The generation rate of heat reduces when burning, and when hot generation rate is decreased below the degree of heat leakage rate
When, burning will stop.Carbon dioxide explosion suppressor has as a kind of novel datonation-inhibition mode
Response time is fast, leakproofness is high, environment-friendly high-efficiency and the features such as high temperature resistant, can gradually obtain extensively
It promotes and applies.
Three, summary of the invention
The purpose of the utility model is to provide it is a kind of it is structurally reasonable, be skillfully constructed, can effectively overcome existing datonation-inhibition mode all
Mostly insufficient pipe used in mine carbon dioxide explosion suppressor.
To achieve the above object, the technical solution adopted in the utility model are as follows: the explosion suppressor includes being built-in with carbon dioxide
Steel cylinder and the nozzle that is fixed on pipe used in mine and is communicated with its inner cavity；Its main feature is that: lead between steel cylinder outlet and nozzle
Cross connector and escape pipe connection；Between connector and escape pipe be equipped with lower part by diaphragm seal sealing, top by air flue with
The explosion venting valve that steel cylinder intracavity communicates；The cylinder body being made of the cylinder of front piston cylinder and rear portion, the cylinder body are equipped on the outside of steel cylinder
It is closed respectively by the front cover and rear cover that have escape pipe two sides；The piston connecting with piston rod, piston rod are equipped in piston cylinder
Be pierced by from cylinder rear portion and connect with cylinder rod, cylinder rod is penetrated in escape pipe and is connect with the pulling block on top, the upper end of pulling block with it is close
Mounting is fixedly connected；It is equipped with the production inflator with trigger on cylinder top, is produced from inflator inner cavity and is communicated with cylinder inner cavity, and be equipped with
The combustion gas agent contacted with trigger.
Using the above structure, in use, through flanged joint on gas tube, while the pipe in the utility model two sides
Flame sensor is installed respectively on road, and flame sensor and trigger are connect by conducting wire with controller.Work as gas tube
When burning or explosion generate flame, pressure, signal is detected by flame sensor and is transferred to controller, controller, which issues instruction, to be made
Trigger triggering produces combustion gas agent in inflator and chemically reacts, and generates bulk gas, and gas enters in piston cylinder through cylinder, pushes away
Piston moves forward, and drives piston rod that cylinder rod is pulled to move forward, and keeps the pulling block on cylinder block top mobile by diaphragm seal
It tears, opens explosion venting valve, the high-pressure carbon dioxide gas in steel cylinder sprays into pipeline through air flue, escape pipe and nozzle, blocks
Flame propagation reaches datonation-inhibition purpose.Wherein venting of dust explosion component primarily serves the effect for releasing stress, hindering flame, so that flame is existed after explosion arrestment
Gas input side discharges rapidly pressure, flame, to weaken flame transmission.The utility model due to using explosion venting valve, it be
A kind of mechanical structure can efficiently play sealing effect, storage pressure, pressure holding effect are very significant, thus effectively by air-tight test
Realization inhibit gas flame explosion purpose.Datonation-inhibition process from detect flame, pressure signal to it is datonation-inhibition only three phases:
Detection, controller, explosion arrestment, it is easy to operate.The utility model is structurally reasonable, is skillfully constructed, and combustion gas agent is closed
In the environment of use, do not influenced by outside air quality；It is at low cost, handling ease, as long as after explosion suppression device is installed just
Can be datonation-inhibition, do not have to replacement any part, saves spending.
