Abstract
The utility model provides a coal bed gas filter equipment, including shell, gas distribution device, filter core, air inlet, gas vent, manhole, desorption gas port, outlet, the inside gas distribution device that is equipped with of shell, the filter core is installed on gas distribution device upper portion, the shell lower part is equipped with the air inlet, and the upper portion both sides are equipped with gas vent and desorption gas port respectively, and the top is equipped with the manhole, and the bottom is equipped with the wash port. The shell bottom is the hemisphere, the outlet lies in the lower of shell bottom intermediate position. When the filter core was passed through to the coal bed gas, water and the dust of filter core in with the coal bed gas adsorbed and filters, the effect of reach dehydration, removing dust, when the filter core saturation, clear air gets into from the desorption gas port, to the filter core wash, the desorption, the outlet discharge of water from the shell bottom.
Description
Technical field
The utility model relates to coal bed gas process field, particularly relates to a kind of coal bed gas filter.
Background technology
The coal bed gas that well head flows out, nearly all by gas phase water is saturated, even can carry a certain amount of aqueous water.In coal bed gas, the existence of moisture often causes serious consequence: the coal bed gas containing CO2 and H2S forms acid in the presence of water and corrodes pipeline and equipment; Form coalbed methane hydrate dissociation under certain condition and block valve, pipeline and equipment; Reduce pipeline transmission capacity, cause unnecessary power consumption.Moisture is very disadvantageous in the existence of coal bed gas, therefore, remove moisture in coal bed gas and dust very necessary.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of coal bed gas filter, comprise shell, distribution device, filter core, air inlet, exhaust outlet, manhole, desorption gas port, discharge outlet, described enclosure is provided with distribution device, described distribution device top is provided with filter core, and described outer casing underpart is provided with air inlet, and both sides, top are respectively equipped with exhaust outlet and desorption gas port, top is provided with manhole, and bottom is provided with discharge outlet.
Described filter core can be one or more.
Described outer casing bottom is hemispherical, and described discharge outlet is positioned at outer casing bottom centre position lowest part.
The beneficial effects of the utility model are: when coal bed gas is by filter core, filter core is by the water in coal bed gas and adsorbing powder dust and filtration, reach the effect of dehydration, dedusting, when filter core is saturated, clean air enters from desorption gas port, filter core is cleaned, desorption, water is discharged from the discharge outlet of outer casing bottom.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, shell; 2, distribution device; 3, filter core; 4, air inlet; 5, exhaust outlet; 6, manhole; 7, desorption gas port; 8, discharge outlet.
As shown in Figure 1, described shell 1 inside is provided with distribution device 2, and described distribution device 2 top is provided with filter core 3, and described shell 1 bottom is provided with air inlet 4, and both sides, top are respectively equipped with exhaust outlet 5 and desorption gas port 7, and top is provided with manhole 6, and bottom is provided with discharge outlet 8.
Described filter core 3 can be one or more.
Be hemispherical bottom described shell 1, described discharge outlet 8 is positioned at centre position lowest part bottom shell 1.
During use, when coal bed gas is by filter core 3, filter core 3 is by the water in coal bed gas and adsorbing powder dust and filtration, reach the effect of dehydration, dedusting, when filter core 3 is saturated, clean air enters from desorption gas port 7, filter core 3 is cleaned, desorption, the water removed is discharged from the discharge outlet 8 bottom shell 1.
Be described in detail of the present utility model by embodiment above, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
