Coal bed gas of the present invention refers to be stored in coal seam using methane as main component, with absorption in matrix of coal particle
Based on surface, partly hydrocarbon gas in coal seam water is free in coal hole or be dissolved in, be the associated minerals resource of coal, category is non-
Conventional gas, it is cleaning, high-grade energy and the industrial chemicals to emerge in the world in nearly ten or twenty year.It is commonly called as " gas ", calorific value
It is 2-5 times of general coal, the calorific value of 1 cubic metre of pure coal bed gas is equivalent to 1.13kg gasoline, 1.21kg standard coals, its calorific value and day
Right gas phase is worked as, and can be mixed with natural gas defeated mixed and very clean after burning, and [1] is nearly free from any waste gas, is first-class
Industry, chemical industry, generating and resident living fuel.When coal bed gas air concentration reaches 5%-16%, meeting naked light will explode, and this is
The root of Gas Explosion Accidents in Coal Mines.Coal bed gas is directly discharged in air, and its greenhouse effects is about 21 times of carbon dioxide, right
Environmental destruction is extremely strong.If first exploiting coal bed methane before coal mining, coal mine gas from explosion rate will reduce by 70% to 85%.
The utilization of coal bed gas have the effect of achieving many things at one stroke：Clear energy sources, commercialization can produce huge economic benefit.For country
Strategic resource.
Draining pump described in this patent, when in use water rotate quickly, the water being rotating is under the influence of centrifugal force from leaf
Flown in wheel, after the water in pump is spilled over, the core of impeller forms vacuum area.The water at water source is in atmospheric pressure (or water
Pressure) in the presence of be pressed onto by pipe network in water inlet pipe.So circulate endlessly, it is possible to realize continuous pumpage.It is worth one herein
It is mentioned that：Centrifugation pump startup is previous will to be full of after water into pump case surely, can be started, otherwise the pump housing will be caused to generate heat, shake,
Water yield is reduced, and water pump is caused to damage, and referred to as " cavitation erosion ", causes equipment breakdown！So-called cavitation erosion refers to：Centrifuge pump startup
When, if air in pump be present, because the density of air is very low, caused centrifugal force very little after rotation, thus institute of impeller central area
The low pressure of formation is not enough to liquid level less than in the liquid suction pump of pump inlet, it is impossible to the phenomenon of trandfer fluid.
First check for whether each several part is stably connected with when being used, confirm equipment components it is complete, well-tended appearance it
Afterwards, equipment is placed on the place that coal bed gas well bottom has water to ooze out, once there is infiltration situation, water enters from water inlet 413, leads to
Cross under the double-deck effect of buoyancy of the upward active force and water of hairspring 414, buoyant mass 412 is floated upwards, the top of buoyant mass 412
The surface of floating lever 410 is provided with screw thread, and first gear 420 starts to be rotated down from left to right while floating, second gear 321 with
For first gear 420 on same axis, then first gear 320 drives second gear 421 to rotate down from left to right, passes through
The transmission of first driving chain 422, first gear 420 and second gear 421 located at the top of fixed block 423 start to do from a left side to
Rotational motion under dextrad, then drive rotary turnplate 425 to be rotated down from left to right by the second driving chain 424, in rotation
Meanwhile the limited block 4251 in rotary turnplate 425 rotates downwards, then apply weight bar 4252 and be pressed in tenesmus and applied on pouring weight 430, applied
Pouring weight 430 is pushed to push upper movable contact 434 and is closely joined together with lower fixed contact 435, realizes the closure of circuit, electricity
Source is connected, and draining pump 44 is started working, and after taking water away discharge, water level decreasing, without the buoyancy of water, hairspring 414 can not prop up
Buoyant mass 412 and the weight of elevating bar 411 are supportted, then tenesmus drives the motion, then lead to upwards from left to right of first gear 420
The transmission crossed between the first driving chain 422 and the second driving chain 424, the then motion upwards from left to right of rotary turnplate 425,
Limited block 4251 moves upwards, will apply weight bar 4252 and tilts, and applies pouring weight 430 and is popped up by the elastic force for recovering spring 437, on
Movable contact 434 separates with lower fixed contact 435, realizes the disconnection of circuit, and power supply disconnects, and draining pump 44 is stopped；Pass through
Automatic draining mechanism can detect whether water source and self-draining purpose to reach draining pump, be arranged automatically in practical coal bed gas well
Hydromining device of air is in use, can detect that whether coal bed gas well bottom has infiltration water outlet situation, and automatic start draining pump is carried out
Draining, avoid because detection draining caused water logging and damage not in time, the effective normal work for ensureing coal bed gas well, favorably
In raising yield.
The present invention solves the problems, such as be coal bed gas well automatic water drainage gas production device can not possess accurately and timely detect seep water out
Water and self-draining function, well water outlet water logging may be caused when serious and influences normally to produce.The present invention passes through above-mentioned part
Be combined with each other, realizing can accurately detect whether coal bed gas well bottom has infiltration water outlet situation, and automatic start draining pump
Draining is carried out, is avoided because detection draining caused water logging and damage not in time, the effective normal work for ensureing coal bed gas well,
Be advantageous to improve yield.
