Abstract

The utility model relates to a dehydration and filtration device for gas, which comprises a gravitational dehydrating device. The dehydration and filtration device for gas is characterized by also comprising a filtering device, and the filtering device is arranged on an internal gas emission part of the gravitational dehydrating device. By adopting the structure, effects of gravitational dehydration and dehumidification can be achieved, particulate impurities in the gas can be filtered, and good purification effects can be achieved. Moreover, the device has a simple structure and good effects.

Description

A kind of dewatering filtering device that is used for coal mine gas
Technical field
The utility model relates to a kind of dewatering filtering device, and especially designing a kind of collection dehydration and filteration that is used for coal mine gas is the dewatering filtering device of one.
Background technology
At present; In the gas power station be mostly before the combustion gas unit with the female pipe coupling of gas in, a gravity dehydration device is installed, by the heavy light physical action of gas of water in the methane gas; Through low in and high out; Remove the moisture in the methane gas, reduce harm, thereby increase the generating efficiency of combustion gas unit unit.But this mode can only guarantee to remove the most of moisture in the methane gas, can not remove the small-particle impurity in the gas, and impurity still can pass through gas transmission pipeline, gets into pipeline and machine, causes the cylinder wall damage.
The utility model content
The utility model technical problem to be solved provides a kind of dewatering filtering device that is used for coal mine gas; Overcome in the existing gas power station be mostly before the combustion gas unit with the female pipe coupling of gas in; A gravity dehydration device only is installed, can not be removed the small-particle impurity in the gas, impurity still can pass through gas transmission pipeline; Get into pipeline and machine, cause the defective of cylinder wall damage.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of dewatering filtering device that is used for coal mine gas; Comprise the gravity dehydration device; Also comprise filtration unit, said filtration unit is arranged on the position that the inside methane gas of said gravity dehydration device is gushed out.
The beneficial effect of the utility model is: not only can well reach the effect of gravity dehydration, reach the effect of dehumidifying, can also filter out the particulate contamination in the methane gas, play good decontamination effect improving, implementation structure is simple, and is respond well.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said filtration unit is a filter screen.The size of filter screen and shape are definite according to giving vent to anger of gravity dehydration device.
Further, said filter screen is 30 order Stainless Steel Cloths.
Further, said Stainless Steel Cloth is 3 to 5 layers.
Further, said filter screen is fixed on the position that the inside methane gas of said gravity dehydration device is gushed out through zinc coated bolt.
Further, said filter screen is divided into subregions such as 4 or 8.
Adopt the beneficial effect of above-mentioned further scheme to be: this filter screen filter screen just can stop foreign matters such as the iron rust of from the female pipe of gas, being with the larger particles of coming, welding slag fall in advance, prevents to get into machine.The particle that filters out is through action of gravity, and the moisture in methane gas sinks in the return water pipe, and female pipe is got back to the atomizing pond through confluxing.
Description of drawings
Fig. 1 the utility model is used for the dewatering filtering device synoptic diagram of coal mine gas;
Fig. 2 is used for the filter structure of the dewatering filtering device of coal mine gas for the utility model.
In the accompanying drawing, the list of parts of each label representative is following:
1, filter screen, 2, the gravity dehydration device.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
The dewatering filtering device that is used for coal mine gas as shown in Figure 1 comprises the gravity dehydration device, also comprises filtration unit, and said filtration unit is arranged on the position that the inside methane gas of said gravity dehydration device is gushed out.
Said filtration unit is a filter screen 1.The size of said filter screen and shape confirm that according to size, the shape of the air outlet of gravity dehydration device said filter screen 1 is 30 order Stainless Steel Cloths.Said Stainless Steel Cloth is 3 to 5 layers.Said filter screen 1 is fixed on the position that the inside methane gas of said gravity dehydration device is gushed out through zinc coated bolt.Said filter screen is divided into subregions such as 4 or 8.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
