Description
Technical field:
The utility model relates in the underground gas extraction pipeline that is applied in the coal mining back-fire relief release slag-draining device that discharges water, before specifically being arranged on down-hole mining work plane extraction arm and district rise main and closing stubble point, at the district rise end opening, in the shaft station, on ground to the back-fire relief release draining deslagging device of the positions such as standpipe end opening of down-hole, so that the underground gas extraction pipe network is divided into block, make it separate, in case catastrophe takes place to realize multistage back-fire relief, catastrophe is controlled at minimum zone.
Background technology:
Gas density in the underground gas extraction pipeline often is in the gas explosion interval range.Permanent or the down-hole mobile system in ground is when adopting wet type extraction pump to carry out gas pumping, gas density in the pipeline is not required, because under the situation of pipeline gas leakage, owing to be the negative pressure extraction, in general gas can not be from the pipe internal leakage outside pipe, and only may air enters in the pipe reduction gas pumping concentration from managing outside, even there is naked light can not propagate in the pipeline in the tunnel, safety does not have significant impact yet.But in order preventing trouble before it happens, to strengthen the safety measure of underground gas extraction system, when carrying out the low concentration gas extraction and utilizing, to take down-hole catastrophe preventive action, the catastrophe that takes place can be controlled at minimum zone.For this reason, need a kind of down-hole back-fire relief release slag-draining device that discharges water, with device be separately positioned on getting working face extraction arm and district rise main close the stubble point before, be arranged on the district rise end opening, be arranged on the shaft station, and the standpipe end opening position that is arranged on ground to down-hole.But, do not have a kind of down-hole back-fire relief release of the suitable practicality slag-draining device that discharges water so far.
The utility model content:
The utility model is for avoiding above-mentioned existing in prior technology weak point, back-fire relief release slag-draining device that discharges water in a kind of down-hole is provided, divide with the block of realizing the underground gas extraction pipe network, make it separate, catastrophe is controlled at minimum zone by multistage back-fire relief.
The technical scheme that the utility model technical solution problem is adopted is:
The discharge water design feature of slag-draining device of the utility model back-fire relief release is to be made of top spark arrester and bottom tailrace,
The top spark arrester has two gas channels up and down, wherein, the middle part of overdraught passage is can be along the two-way mobile dull and stereotyped spool of airflow direction, the both sides of dull and stereotyped spool are respectively established closure plate one, closure plate is provided with circular channel, dull and stereotyped spool has two states, and the one, dull and stereotyped spool is between two side stopboards and with two side stopboards and is separated, and the periphery of dull and stereotyped spool and the circular channel in the closure plate form the upper air passage; Another is that dull and stereotyped spool reclines the upper air pathway closure because of impacted with side stopboard formation by air pressure; The downstream passage is the water seal passage, and is undertaken on the below of upper air passage, in the lower stream of airflow passage, be respectively arranged with water injection valve, residual cake valve and with the water cavity of upper air channel connection;
The bottom tailrace is positioned at the bottom of downstream passage.
Design feature of the present utility model also is
In the upper air passage, be provided with pressure relief opening.
Dull and stereotyped spool is to be provided with its top suspension suspention.
The utility model utilizes gas combustion explosion time pressure to be ahead of the principle that flame speed is propagated.Two gas channels up and down are set in device, and under the normal condition, gas is by the upper air passage, from air inlet side access to plant, the circular channel on air inlet one side stopboard of flowing through is walked around around the bidirectional plate spool, circular channel on the side stopboard of giving vent to anger again, effluent goes out from giving vent to anger.If in the pipeline of air inlet side, produce gas explosion, impact air-flow pressure is during greater than the bidirectional plate spool self-closing pressure value set, the bidirectional plate spool is under impact air-flow promotes, moment is sealed the circular channel on the side stopboard of giving vent to anger, and the flame flow of Dao Laiing can only pass through lower stream of airflow passage, i.e. water seal gas channel subsequently, air-flow heads on the water motion in the water cavity, make current enter the lateral line of giving vent to anger, cut off the flame transmission passage, thereby realize the back-fire relief purpose prior to air-flow.
The utility model is provided with the bottom tailrace simultaneously, and when the water in the inflow water cavity in the pipeline surpassed waterline, water flowed into tailrace from oral siphon, and after the certain water yield of tailrace inner accumulated, open automatically with unnecessary water discharging the dewatering outlet.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utlity model has the back-fire relief pressure relief, and the deslagging that can discharge water, with its be separately positioned on getting working face extraction arm and district rise main close the stubble point before, be arranged on the district rise end opening, be arranged on the shaft station, be arranged on the standpipe end opening position of ground to down-hole, can realize the block division of underground gas extraction pipe network, make it separate, catastrophe is controlled at minimum zone by multistage back-fire relief.
2, the utility model is provided with the two-way valve structure, no matter in the air inlet side or the side pipe road of giving vent to anger catastrophe takes place, can both play the fire arresting effect.
3, the utility model can be arranged in suction side pipeline and the down-hole pipeline, also can be arranged on malleation lateral line and ground gas electricity machine inlet end, can realize between the gas electricity unit and supply air line in when catastrophe takes place, independent each other back-fire relief is controlled at minimum zone with catastrophe.
