Natual gas dehydrate unit filter
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of natual gas dehydrate unit filter.
Background technology
In order to alleviate energy scarcity, decreasing pollution, natural gas, as clean energy resource, is applied in increasing place.Natural gas can with the moisture of hydrone two kinds of forms in the water of free state and gaseous component in recovery process.Wherein, the water of free state can produce electrochemical corrosion, can make the inner severe corrosion damage of transport line; Hydrogen sulfide in natural gas and carbon dioxide and water react the sulphur hydracid that generates and carbon acid also can cause certain corrosion to transport pipeline.If natural gas is dewatering and filtering not, if things go on like this, transport pipeline may be made to leak and cause security incident, also can bring serious economic loss to enterprise.In order to avoid the generation of accident and loss, need natural gas dry filter.Natual gas dehydrate unit filter of the prior art, in order to will air inlet and exhaust piper road and cylindrical shell not take apart when more renew cartridge, adopts the mode that cylindrical shell is connected with bolt of cover, when more renew cartridge, is dismantled by end cap.But being column structure for filter core, in order to increase the contact area of filter core and natural gas, improving filter effect, can only increase the length of filter core, this just makes the height of cylindrical shell increase, when more renew cartridge, workman just can must finish the work by higher ladder, adds replacing difficulty; And due to workman's operation aloft, also easily there is security incident.
Utility model content
For the defect that above-mentioned prior art exists, technical problem to be solved in the utility model is to provide that a kind of cylindrical shell height is low, take up room little, that more renew cartridge is safe and efficient natual gas dehydrate unit filter.
In order to solve the problems of the technologies described above, the utility model provides a kind of natual gas dehydrate unit filter, comprises bolted end cap and cylindrical shell, and described cylindrical shell lower end is globoidal structure and is provided with draining valve, and the side of cylindrical shell is provided with air inlet and gas outlet.Be provided with filter core, tubular support and filter plate in described cylindrical shell successively, described filter core is made up of the ring-type filter block that multiple diameter is different, and the diameter of ring-type filter block reduces from bottom to top successively, and ring-type filter block largest outer diameter is identical with the interior diameter of cylindrical shell; Described filter plate is pyramid type, is provided with the connecting end surface of level in the middle part of it, and filter plate edge is evenly equipped with multiple semicircle orifice; Tubular support one end is fixedly connected with cartridge support ring, and the other end is fixedly connected with connecting end surface; Air inlet is between cartridge support ring and filter plate, and gas outlet is between cartridge support ring and end cap.
Further improvement as the utility model above-mentioned natual gas dehydrate unit filter: the axial height of described ring-type filter block is 15 ~ 18cm, and radial thickness is 10 ~ 15cm; Ring-type filter block one end is provided with projection, and the other end is provided with the groove that the projection that is adjacent ring-type filter block adapts.
Further improvement as the utility model above-mentioned natual gas dehydrate unit filter: the diameter that described filter plate projects at horizontal plane is identical with cylindrical shell interior diameter; Filter plate has several treatment hole, treatment hole diameter is 0.8 ~ 1.2mm.
Further improvement as the utility model above-mentioned natual gas dehydrate unit filter: described air inlet and exhaust ports are equipped with corresponding pressure-display device.
The natual gas dehydrate unit filter tool of said structure is adopted to have the following advantages: (1) is made up of the ring-type filter block that multiple diameter is different due to filter core, the lower surface of ring-type filter block can contact with natural gas, while the enough contacts area of guarantee, reduce the height of filter core, and then the height of cylindrical shell can be reduced, make workman can carry out filter element replacing on the ground, and do not need to use the aids such as ladder, safe and reliable; (2) because filter core is made up of the ring-type filter block that multiple diameter is different, certain ring-type filter block can be changed, to make filter core ensure filter effect all the time, and save the use cost of filter core; (3) filter plate is pyramid type, filter plate edge is evenly equipped with multiple semicircle orifice, and when in natural gas, the water of free state strikes on filter plate, the water of free state is separated and flows into the semicircle orifice at filter plate edge along filter plate, be slides quickly into the bottom of cylindrical shell again along cylinder inboard wall, drainage speed is fast; (4) because filter core adopts tubular support and cartridge support ring to support, not only can with cylindrical shell separating making, easy to process, with low cost, and its body is lightweight, materials are few; (5) because filter core is fixed on tubular support by cartridge support ring, when filter plate blocking needs to change, after filter core is taken out, can filter plate be taken out by tubular support and change.

Detailed description of the invention
In order to better understand the utility model, now specific embodiments of the present utility model is described in detail by reference to the accompanying drawings:
The utility model provides a kind of natual gas dehydrate unit filter, and as shown in Figures 1 to 4, end cap 1 is fixedly connected with by six bolts being distributed on end cap 1 week side with cylindrical shell 2; Cylindrical shell 2 lower end is that globoidal structure is welded with draining valve 3, and the side of cylindrical shell 2 is also welded with air inlet 4 and gas outlet 5.Air inlet 4 and exhaust ports are equipped with corresponding pressure display unit 13.Filter core, tubular support 10 and filter plate 7 is provided with successively in cylindrical shell 2, this filter core is made up of five ring-type filter blocks 6 that diameter is followed successively by 10cm, 11cm, 12cm, 13cm and 15cm from bottom to top, ring-type filter block 6 largest outer diameter is identical with the interior diameter of cylindrical shell 2, the axial height of ring-type filter block 6 is 15cm, under this height, the dewatering efficiency of natural gas flow and filter block 6 is best.Ring-type filter block 6 one end is provided with projection, and the other end is provided with the groove that the projection that is adjacent ring-type filter block 6 adapts.During use, the horizontal plane of ring-type filter block 6 also can contact with natural gas, while the enough contacts area of guarantee, reduces the height of filter core, and then can reduce the height of cylindrical shell 2, save the processing cost of cylindrical shell 2.Certain ring-type filter block 6 can also be changed, to make the entirety of filter core ensure filter effect all the time, and save the use cost of filter core.Filter plate 7 is pyramid type structure, and the middle part of filter plate 7 is provided with the connecting end surface 8 of level, and filter plate 7 edge is evenly equipped with 26 semicircle orifices 9, like this, the water of free state not only along the inwall of cylindrical shell 2 by semicircle orifice 9, also can slip into semicircle orifice 9 along filter plate 7, increase filter efficiency.The diameter that filter plate 7 projects at horizontal plane is identical with cylindrical shell 2 interior diameter, in order to improve the efficiency that it filters free state moisture content when not affecting filter plate 7 intensity, filter plate 7 has the treatment hole 12 that several diameter is 1mm, to increase the efficiency of filtering free state moisture.Tubular support 10 one end is welded with cartridge support ring 11, and the other end and connecting end surface 8 are bolted to connection, and when filter plate 7 changed by needs, by lift cartridge support ring 11, filter plate 7 can be taken out.Air inlet 4 is between cartridge support ring 11 and filter plate 7, and gas outlet 5 is between cartridge support ring 11 and end cap 1.
