Abstract
The utility model discloses a double-tank water seal type explosion-proof and anti-backfire device. The device can be mounted on a pipeline near to the inlet and the outlet of a gas drainage pump of a coal mine, and comprises a gas inlet pipe, a water-sealed tank and a pressure relief tank, wherein the lower outlet of the gas inlet pipe is submerged under the water surface in the water-sealed tank; the water-sealed tank and the pressure relief tank are mutually communicated through a communicating pipe; and an exhaust pipe is arranged on the pressure relief tank and communicated with the gas inlet end of the gas drainage pump. Methane gas and atomized water for water sealing, which enter the device, are fully separated and fall down by adopting the methods of speed reduction, centrifugation, direction change, secondary separation and the like, so that the problem that water for water sealing of other water seal type explosion-proof and anti-backfire device possibility drains or is discharged completely is successfully solved, meanwhile, the loss of water for water sealing is greatly reduced. Owing to the design and installation of an automatic water replenishment device and an automatic water drainage device, the water seal position of the device is kept stable within a certain range, and the explosion-proof and anti-backfire functions are guaranteed.
Description
Affiliated technical field
The safety device of design that the utility model is in aiming at, large-scale colliery draws out methane is installed near the pipeline gas pump intake and the outlet.
Background technology
At present, domestic gas discharge in mine pumping plant adopts the explosion-proof fireproof tempering device of hydrolock more.Because the defective that apparatus structure exists, often occurring being used for the mixed gas pump drainage of explosion-proof, anti-backfire water seal water in the use does, make this device lose explosion-proof anti-backfire performance, in case gas combustion or blast appear in downstream user or pumping plant, all can threaten the safety of gas pumping station and down-hole extraction system even mine.Even often use artificial recharge, also too fast huge with the water consumption because of the loss of water, can not keep water seal constant, do not have due protective effect.
Summary of the invention
Easily done in order to overcome existing explosion-proof fireproof tempering device water seal water by pump drainage, problems such as the water consumption is bigger than normal, the utility model provides the novel two jars of explosion-proof fireproof tempering devices of hydrolock, this device has not only solved the water seal water and has easily been done by pump drainage, problems such as the water consumption is bigger than normal have also solved water seal constant problem in allowed band.
Two jars of explosion-proof fireproof tempering devices of hydrolock of the utility model, be installed in gas suction pump turnover gas two ends, this device comprises air inlet pipe, water sealed tank, pressure release jar, the following outlet of air inlet pipe is submerged under the interior water surface of water sealed tank, be communicated with by communicating pipe between water sealed tank and the pressure release jar, the pressure release jar is provided with stack, and this stack is connected with the gas suction pump inlet end.
Further, described communicating pipe is obliquely installed, and tank body with described pressure release jar is tangent is connected for it.
Further, be provided with return pipe between described water sealed tank and the pressure release jar, return pipe is provided with U-shaped pipe tailrace, and the pressure release jar is provided with automatic water replenishing device.
The technical scheme that its technical problem that solves the utility model adopts is: use two jars of explosion-proof fireproof tempering devices of hydrolocks of principle development such as reduction of speed, centrifugal, break-in, cohesion, secondary separation, reduced the gas flow rate of this device of flowing through; Suitably increase the tank body volume, increased water retention capacity; Change gas flow.Make to be blown afloat and separate rapidly with the water that atomizes and fall after rise, successfully solved the problem that the explosion-proof fireproof tempering device water seal of other hydrolock water is easily drained or drained by gas.By design and installation automatic water replenishing device and automatic tailrace, make this device water seal position in allowed band, keep constant, explosion-proof anti-backfire effect is guaranteed.
The beneficial effects of the utility model are, by structure design, have solved explosion-proof fireproof tempering device water seal water and have easily been done problem by pump drainage, have significantly reduced the water consumption.Assisting down of automatic water replenishing device and automatic tailrace, make device water seal position keep constant within the specific limits.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the communicating pipe generalized section.
1. air inlet pipe among Fig. 1,2. water sealed tank, 3.U shape pipe tailrace, 4. return pipe, 5. communicating pipe, 6. water-line target line (soil cleaning port), 7. pressure release jar, 8 stacks, 9 automatic water replenishing devices.
The specific embodiment
In Fig. 1, during the normal extraction of gas, in tank body, add the envelope water of pouring water in advance, make it to flood under this device water sealed tank air inlet pipe and export, form annular water seal, i.e. water level marker line to the water level.After starting working, under gas suction pump negative pressure or malleation (inlet end or outlet side) effect,, wash the annular water seal of 1 time outlet of air inlet pipe continuously open, enter water sealed tank 2, be covered with in water sealed tank by increasing the methane gas that the air inlet pipe caliber has reduced flow velocity.In the vaporized while of water seal water, also in gas-water separation.Simultaneously, the gas air water after separating for the first time through between water sealed tank 2 and the pressure release jar 7, press the tube connector 5 of certain angle inclination, enter in the pressure release jar 7 along the pressure release tank line direction of cutting sth. askew.Device in Gas in the pressure release jar 7, water are through after centrifugal, break-in, cohesion, the secondary gas-water separation, and water seal water great majority have been stayed in the jar, and Device in Gas enters gas suction pump inlet end or gas drainage under suction tube drainage end along the stacks in the pressure release jar 7.In case when gas explosion and burning took place in the pipe, flame was completely cut off by water seal, simultaneously, blast wave breaks through the pressure release offset plate on the pressure release jar 7, and explosion energy obtains discharging, so can protect the safety of down-hole, terrestrial user or pump house.Automatic water replenishing device that this device is set up and U-shaped pipe tailrace make this device water seal water level keep constant in the certain limit, guarantee that the water seal water is not done by pump drainage and the interior retaining of pipe too much increases the extraction resistance.
Fig. 2 is the communicating pipe sectional drawing.Water sealed tank is by downward-sloping and be combined into one with tangent communicating pipe and the pressure release jar of pressure release tank, the air water that has not only changed from water sealed tank to the pressure release jar flows to, air water is rotated along pressure release jar inwall, produce centrifugal and cohesion, make the air water secondary separation more abundant, the loss of water seal water still less.
