Description
Technical field
The utility model relates to a kind of coal mine gas exhaust device.
Background technology
The colliery has a large amount of gas to produce in mining process, and directly safety is produced, threatened in influence.Gas drainage under suction is the most effective, the essential method that solves the gas problem at present.Existing gas discharge in mine device comprises: water ring vacuum pump, moisture trap, drift dewatering ditch, wellhole and big pump, water ring vacuum pump is connected with moisture trap by pipeline, the gas outlet of moisture trap is connected with a gas pipeline that stretches out in ground, the delivery port of moisture trap is connected with wellhole by the drift dewatering ditch, and big pump water inlet mouth is located at the sump bottom.During use, water ring vacuum pump enters moisture trap with external water source and gas, gas is wherein introduced ground gas jar or directly emptying by the gas outlet and the gas pipeline of moisture trap, and water wherein then enters in the sump by the drift dewatering ditch and discharges ground by big pump again.Because of the influence of system water supply pipeline with use too that buck makes pump housing fouling finally cause gas drainage under suction to be forced to stop as resource of water supply.Water ring vacuum pump is by 1 of every month disassembling, assembling and replacing, and the time stopped production each 6 hours by each 6 hours, will cause at least 2.52 ten thousand tons/year of the underproduction, and coal price is by 400 yuan of/ton calculating, and the output value in 1 year is with a toll of 10,080,000 yuan.Influenced the loss that causes because of supply channel in every month and calculated by 12 hours every month, will cause annual 4.54 ten thousand tons of the underproduction, the direct losses in 1 year reach 2,016 ten thousand yuan.
The ventilation equipment that carry out gas drainage under suction are water ring vacuum pumps.Water ring vacuum pump must have abundance, reliable resource of water supply.Mostly resource of water supply has two classes under the coal mine: a class is a surface water, and aboveground have an enough big pond, is connected with water ring vacuum pump by pipeline; Another kind of is to adopt underground water.Such as, too buck is made the production water source of mine.Utilize fire-fighting dirt pipeline and water ring vacuum pump to be connected.No matter be which kind of water source, water ring vacuum pump all can be subjected to the influence of extraneous factor and cause termination of pumping, this problem of invar and influence production.Influence factor mainly contains: water system influence, output deficiency; Planned maintenance pipeline etc.In case water ring vacuum pump shuts down, this transfinites and is forced to stop production will to cause the work plane invar, has a strong impact on mine safety.Simultaneously, traditional coal mine gas exhaust device causes big water gaging to need discharging, and annual effluent cost is considerable.
This creator actively makes great efforts research, through research and development with great concentration, invents out the utility model of true tool practical effect and industrial utilization finally.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, antijamming capability is strong, operating cost is low coal mine gas exhaust device.
For achieving the above object, the utility model is taked following design scheme: a kind of coal mine gas exhaust device, and it is characterized in that: it comprises: water tank, water ring vacuum pump and moisture trap; Described water tank is connected with the water ring vacuum pump water inlet by pipeline, described water ring vacuum pump outlet is connected with described moisture trap by pipeline, the gas outlet of described moisture trap is connected with a gas pipeline, and the delivery port of described moisture trap is connected with described water tank by pipeline.
The utility model has the advantages that:
1, the utility model is owing to adopt above design scheme, a certain amount of water (height of water level is higher than the centrad degree of water ring vacuum pump in the water tank) of packing in the water tank during use, water ring vacuum pump is discharged to the gas in water in the water tank and the extraction boring in the moisture trap, moisture trap is introduced ground gas jar or directly emptying with gas wherein by gas pipeline, and water is wherein gone in the water tank by channel flow.So, water circulates between water tank, water ring vacuum pump and moisture trap so that the gas exhaust in the colliery is arrived ground.Change many disadvantages of the acyclic way of supplying water that current China generally uses, as the safety problem that causes of cutting off the water, changed plant issue, water pump power consumption problem etc.
2, the utility model is simple in structure, invests for a short time, and technical requirements is low, implements easily, and any unit can transform traditional exhaust device according to this design scheme, and very fast coming into operation.
3, compared with prior art, because the effluent cost that the utility model has been saved big pump, so can 10,000 kilowatt hour/years of using electricity wisely.Adopt the periodical feeding mode, not can because of cut off the water, reasons such as water pump fault, system's fouling, cause to stop to discharge the safety problem of being brought.Adopt the periodical feeding mode, 15.984 ten thousand side/years of using water wisely, about 17.58 ten thousand yuan/year.
4, the utility model is avoided reaching 3,024 ten thousand yuan because of the direct economic loss that water system influences and pump body structure is caused.Also saved certain maintenance cost simultaneously.

The specific embodiment
As shown in Figure 1, the utility model coal mine gas exhaust device, it is characterized in that: it comprises: water tank 1, water ring vacuum pump 2 and moisture trap 3; Water tank 1 is connected with water ring vacuum pump 2 water inlets by pipeline 5, water ring vacuum pump 2 outlets are connected with moisture trap 3 by pipeline 6, the gas outlet of moisture trap 3 is connected with a gas pipeline 4, and the delivery port of moisture trap 3 is connected with water tank 1 by pipeline 7.
A certain amount of water (height of water level is higher than the centrad degree of water ring vacuum pump in the water tank) of packing in the water tank 1 during use, water ring vacuum pump 2 is discharged to the water in the water tank 1 and the extraction ducted gas of holing in the moisture trap 3 by pipeline 5 and air entry 8, moisture trap 3 is introduced ground gas jar or directly emptying with gas wherein by gas pipeline 4, and water wherein flows in the water tank 1 by pipeline 7.So, water circulates between water tank 1, water ring vacuum pump 2 and moisture trap 3 so that the gas exhaust in the colliery is arrived ground.
Recirculated water in the utility model can with the down-hole too buck as the water source, thereby obtain following effect: 1, be convenient to carry out water demineralization; 2, strengthen antijamming capability; 3, reduce effluent cost.But recirculated water is made in use down-hole too buck, because the too grey water hardness is bigger, make easily on pump housing inwall and the impeller and fouling occurs, cause impeller to damage, cause system to run well, so must add an amount of acid chemical substance in the water in the water tank 1, the pH value of rationally regulating water is in a certain scope, can realize water demineralization, avoid water ring vacuum pump 2 impaired.
The above;, be not that attempt is done any pro forma restriction to the utility model according to this, only so every under the creation spirit of the utility model for being used for explaining the preferred embodiment of the utility model; any modification or the change done all must belong to the scope that the utility model is intended to protection.
