Abstract
A kind of Wet-dry formula turbine pump gas pumping device, mainly comprises drainage tube, safety device, turbine pump, moisture separator, wet type force (forcing) pump.When in drainage tube, gas density is less than 25%, wet type force (forcing) pump is in running order, and wet type extraction pattern enabled by turbine pump, and when being greater than 25%, wet type force (forcing) pump quits work, and dry type extraction pattern enabled by turbine pump.This device can carry out Wet-dry formula gas pumping, and its structure is simple, running cost is cheap, easy to operate, Be very effective, can realize turbine pump gas pumping Wet-dry, energy-conserving and environment-protective, for control of coalmine gas and utilization provide new safety guarantee.
Description
Technical field
The utility model relates to a kind of device of mine gas extraction system, especially a kind of Wet-dry formula turbine pump gas pumping device.
Background technology
In coal mine gas drainage work, " safety regulations in coal mine " the 148 article of Section 1 regulation, draw out methane and must observe and " when utilizing gas; gas density must not lower than 30%, and the safety device of anti-backfire, anti feedback and blast protection effect must be equiped with in the system utilizing gas.Do not utilize gas, adopt dry type draw out methane equipment time, the concentration that draws out methane must not lower than 25% " regulation.Current coal mine gas drainage generally uses water ring pump to carry out wet type extraction, but water ring pump is due to himself operation characteristic, enough operating frequencys must be possessed, power consumption is large, and volume is larger, floor space is also large, under the present situation that colliery economy is descending, how to realize the key that energy-conservation extraction becomes coal mine gas hazard management and using energy source.
Utility model content
The utility model object is the weak point overcome in prior art, provides a kind of structure simple, uses energy-conservation Wet-dry formula turbine pump gas pumping device.
To achieve these goals, Wet-dry formula turbine pump gas pumping device of the present utility model, form primarily of drainage tube, safety device, turbine pump, moisture separator, wet type force (forcing) pump, evacuated tube, gas utilization pipe access in moisture separator respectively, and be connected by tube connector, shower nozzle to be arranged in drainage tube and to receive on wet type force (forcing) pump, and wet type force (forcing) pump is connected on moisture separator by water pipe, moisture separator is connected with water inlet pipe, blow-off pipe, and inside is provided with screen cloth.Shower nozzle is arranged on turbine pump both sides, and the valve that pipeline connects is explosion-proof solenoid valve.
Beneficial effect: owing to have employed technique scheme, when in drainage tube, gas density is less than 25%, wet type force (forcing) pump is fetched water from moisture separator, in drainage tube, water smoke is sprayed by shower nozzle, wet type extraction pattern enabled by turbine pump, and the gas in drainage tube is after safety device, and the water sprayed with shower nozzle mixes, enter under turbine pump pump action in moisture separator, gas to enter in gas utilization pipe through filter screen because density is little and utilizes.If value is less, gas enters evacuated tube through tube connector, does emptying process.When in drainage tube, gas density is greater than 25%, wet type force (forcing) pump is in off position, and dry type extraction pattern enabled by turbine pump, and the gas in drainage tube is from after safety device, directly enter gas utilization pipe by tube connector by turbine pump, enter gas utilization program.
Turbine pump Wet-dry formula gas pumping is carried out in circulation like this.Its structure is simple, running cost is cheap, easy to operate, Be very effective, turbine pump gas pumping Wet-dry can be realized, efficient gas pumping is carried out, energy-conserving and environment-protective, for control of coalmine gas and utilization provide new safety guarantee in guarantee system safety operation situation.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure: drainage tube-1, safety device-2, shower nozzle-3, turbine pump-4, tube connector-5, valve-6, evacuated tube-7, valve-8, gas utilization pipe-9, valve-10, valve-11, valve-12, water inlet pipe-13, valve-14, blow-off pipe-15, screen cloth-16, aqueous vapor separator box-17, valve-18, water pipe-19, nozzle connecting adapter-20, valve-21, wet type force (forcing) pump-22.
Detailed description of the invention
Below in conjunction with accompanying drawing, an example of the present utility model is described further:
Wet-dry formula turbine pump drainage device of the present utility model, it is characterized in that: form primarily of drainage tube 1, safety device 2, turbine pump 4, moisture separator 17, wet type force (forcing) pump 22, evacuated tube 7, gas utilization pipe 9 access in moisture separator 17 respectively, and be connected by tube connector 5, shower nozzle 3 is arranged in drainage tube 1, turbine pump 4 both sides, and receive on wet type force (forcing) pump 22, wet type force (forcing) pump 22 is connected on moisture separator 17 by water pipe 19, moisture separator 17 is connected with water inlet pipe 13, blow-off pipe 15, and inside is provided with screen cloth 16.Described valve 6,8,10,11,12,14,18,21 is explosion-proof solenoid valve.
The course of work: when gas density is less than 25% in drainage tube 1, valve 21,18,11,10 is opened, wet type force (forcing) pump 22 is fetched water from moisture separator 17 by water pipe 19, and supplied water to shower nozzle 3 by nozzle connecting adapter 20, shower nozzle 3 sprays water smoke to drainage tube 1, wet type extraction pattern enabled by turbine pump 4, gas in drainage tube 1 is after safety device 2, the water sprayed with shower nozzle 3 mixes, enter in moisture separator 17 through valve 11 under turbine pump 4 pump action, gas is entered in gas utilization pipe 9 by valve 10 because density is little.If value is less, also can valve-off 10, open valve 8, valve 6, gas enters evacuated tube 7 through tube connector 5, does emptying process.When in drainage tube 1, gas density is greater than 25%, valve 21,18,11,10,6 is closed, wet type force (forcing) pump 22 is in off position, dry type extraction pattern enabled by turbine pump 4, gas from drainage tube 1 after safety device 2, by turbine pump 4 directly by tube connector 5, valve 8, valve 10, enter gas utilization pipe 9, enter gas utilization program.
In plant running process, in moisture separator 17, the impurity such as incrustation scale has deposition, regularly can open valve 14, discharge water through blow-off pipe 15, open valve 12 simultaneously, be injected the water of q.s by water inlet pipe 13.
The rest may be inferred, carries out turbulence pump Wet-dry gas pumping by said apparatus circulation.
