Technical field: the present invention relates to a kind of can be effectively, the purifying device for natural gas of impurity in the filtering natural gas supply system reliably, it can be widely used in fields such as petrochemical industry, metallurgy.
Background technology: present existing purifying device for natural gas does not have the automatic sludge discharge recoiling device, after using for some time, because impurities is left in the strainer in the medium, partial impurities is blocked on the slit of filter post interlayer, thereby can not work on, simultaneously also increased working strength of workers, greatly reduced the working efficiency of strainer, the circuit design of existing purifying device for natural gas is also unreasonable simultaneously.
Summary of the invention: the objective of the invention is at existing purifying device for natural gas exist can not non-stop run shortcoming, but provide a kind of Sweet natural gas filtering and purifying of automatic sludge discharge self-stip, this device is by coarse filtration for the first time, secondary is smart to be filtered and the deslagging processing, can effectively purify, simultaneously polluted air not again gas medium.
Technical scheme of the present invention is: a kind of purifying device for natural gas, comprise tornado dust collector, strainer, deslagging jar and sewage scratch pool, tornado dust collector connect inlet mouth, tornado dust collector upper end pneumatic outlet links to each other with the mistake filter inlet, the impurity outlet connects the deslagging jar by pipeline, strainer is provided with the pure qi (oxygen) outlet, the bottom is provided with slag-drip opening and connects the deslagging jar by pipeline, or directly be connected with the sewage scratch pool, the deslagging jar is provided with water-in, its bottom links to each other with the sewage scratch pool by pipeline, and the deslagging jar is provided with venting port and communicates with blow-down pipe, but above-mentioned strainer is an automatic sludge discharge self-stip natural gas filter.
Its middle filtrator comprises electric motor, step-down gear, transmission shaft, cartridge filter, differential pressure pilot, deslagging recoil tube, housing import and export, electric motor links to each other with step-down gear, the output terminal of step-down gear connects transmission shaft, housing internal fixing cartridge filter, Filter column is arranged in the cartridge filter, and the deslagging recoil tube is fixed on the transmission shaft, recoil tube by spring application on the cartridge filter upper and lower end face, housing is provided with gas feed, and cartridge filter is provided with pneumatic outlet, and the deslagging recoil tube is provided with the impurity outlet.Differential pressure pilot is arranged in the strainer, and wherein two ports connect the clear air cavity and the foul smell chamber of strainer respectively.
The present invention adopts said structure, has that precision height, filtration area are big, characteristics of self-stip and back flushing, operating safety, can be widely used in industries such as petrochemical industry, metallurgy.The strainer of this device can utilize self pressure realization self-stip Filter column, cleans and do not need to pull down Filter column, does not also need to join in addition cleaning system; This machine jar body is divided into table air cavity and foul smell chamber by cartridge filter, and deslagging recoil tube and Filter column are contained in respectively in two chambeies, thereby back flushing is reliable, durable; This machine Filter column is to twine with the Stainless Steel Wire of trapezoid cross section to be welded on many ribs skeleton and to make, and forms the secondary filter slit between every adjacent two steel wires, and filter residue is got rid of smoothly; This machine can be furnished with several Filter columns in tank body, make full use of filter space, and its effective filtration area is 2-3 a times of inlet area, and the recoil frequency is low, and drag losses is little, has dwindled the volume of strainer significantly; This machine can be provided with the safeguard protection clutch coupling in addition, when guaranteeing that this machine runs into the excess load resistance in back flushing work, can in time throw off the power protection mechanism and exempt from destruction.
Description of drawings: Fig. 1 is a whole connection diagram of the present invention.
Fig. 2 is a filter structure schematic representation of the present invention.
Fig. 3 is strainer external form figure of the present invention.
Fig. 4 is a strainer Filter column structural representation of the present invention.
Fig. 5 is a strainer recoil tube structural representation of the present invention.
Embodiment: the specific embodiment of the present invention is described further: a kind of purifying device for natural gas below in conjunction with accompanying drawing, comprise tornado dust collector 14, strainer 15, deslagging jar 16 and sewage scratch pool 17, tornado dust collector connect inlet mouth, tornado dust collector upper end pneumatic outlet links to each other with filter inlet, the impurity outlet connects the deslagging jar by pipeline, strainer is provided with the pure qi (oxygen) outlet, the bottom is provided with slag-drip opening and connects the deslagging jar by pipeline, or directly be connected with the sewage scratch pool, the deslagging jar is provided with water-in, its bottom links to each other with the sewage scratch pool by pipeline, the deslagging jar is provided with venting port and communicates with blow-down pipe, but above-mentioned strainer is an automatic sludge discharge self-stip natural gas filter.
Its middle filtrator comprises electric motor 12, step-down gear 11, transmission shaft 9, cartridge filter 13, differential pressure pilot 7, deslagging recoil tube 4, housing import and export 5,6, electric motor links to each other with step-down gear, the output terminal of step-down gear connects transmission shaft, be provided with safety clutch 10 therebetween, housing internal fixing cartridge filter 13, Filter column 8 is arranged in the cartridge filter, the deslagging recoil tube is fixed on the transmission shaft, recoil tube by spring application on the cartridge filter upper and lower end face, housing is provided with gas feed, cartridge filter is provided with pneumatic outlet, and the deslagging recoil tube is provided with the impurity outlet.Differential pressure pilot is arranged in the strainer, and two port connects the clear air cavity and the foul smell chamber of strainer respectively.1 is electronic residual cake valve, and 2 is the manual blowdown valve, is used for the impurity in the discharge filter, and 3 is hand hole.Filter column 8 is twined to be welded on many ribs skeleton by the Stainless Steel Wire of trapezoid cross section to be made.
Gaseous media enters tornado dust collector by inlet mouth during use, under of the effect of this gaseous media, carry out preliminary coarse filtration at tornado dust collector, enter the smart once more filtration of strainer through preliminary filtering gas by pipeline, and the impurity of discharging from tornado dust collector is discharged into the deslagging jar by the road, gas enters Filter column by housing in strainer, discharge by cartridge filter behind the post after filtration, promptly finished the secondary filtration of gas.But because impurities is left in the strainer in the medium, partial impurities is blocked on the interior slit of filter post layer, thereby advance, pressure change can take place in top hole pressure, after the pressure change value surpasses the technology set-point, by differential pressure pilot 7 control electric motor work, the drive step-down gear rotates, thereby drive the transmission shaft rotation, the deslagging recoil tube is under the drive of transmission shaft, when its slag-drip opening overlaps with the import of filter post, there is a very big pressure difference in filter interior and the deslagging recoil tube, the logical Filter column seam of medium (Sweet natural gas) flows into scum pipe, drains into the deslagging jar together with waste residue, reaches the purpose of self-stip, when pressure returns to original pressure difference, stop back flushing work automatically by differential pressure pilot; Waste residue in the deslagging jar enters the sewage scratch pool by pipeline, and the deslagging jar is provided with water-in, can clean the deslagging jar, and be provided with blow-down pipe, to play hypotensive effect.
