Description

High-Performance Gas Filter

Affiliated technical field

The utility model relates to a kind of gas purification filter.

Background technology

As shown in Figure 1, existing a kind of pneumatic filter has columniform housing 2, its upper and lower two parts are sealedly and fixedly connected by flange 3, there is the filter course 4 of stainless steel sleave compacting at the middle part, gas to be filtered enters from bottom air inlet 5, discharge from top vent 1 through the clean gas after the filtering layer filtration, be filtered layer impurity that stops and fine droplet and pool bulky grain drop drippage, regularly discharge from bottom leakage fluid dram 6.Its shortcoming is that filter effect is undesirable, and the gas purification purity of discharge is not high enough, easily stops up or the follow-up running device that weares and teares, and causes the final products quality on the low side.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of High-Performance Gas Filter that gas is fully filtered is provided.

The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of High-Performance Gas Filter, on the housing, following two parts are fixedly connected by flange seal, housing has air inlet, exhaust outlet, leakage fluid dram, it is characterized in that having the filter of forming by orifice plate and filter vat, orifice plate is connected with housing seal, filter vat is corresponding one by one with the hole on the orifice plate, bucket wall upper end is connected with pore plate by sealing, bucket wall structure is followed successively by the outer band opening supporting mass from outside to inside, outer stainless steel cloth, filter core, interior stainless steel cloth, interior supporting mass with holes, the bucket end, have the interlayer base plate, upper plate is connected with bucket wall inner seal, lower shoe is tightly connected with bucket wall lower end, and lower shoe is tightly connected by pod apertures in the middle of it and the mozzle that leads to the filter housings bottom.

The beneficial effects of the utility model are as follows: gas to be filtered must be respectively just can enter in the bucket from the periphery of each filter vat after the bucket wall filters, hole on orifice plate rises to the filter top discharge again, impurity that filters and fine droplet pool the bulky grain drop and drop in the interlayer base plate along the bucket wall, flow out from the mozzle that is connected with lower shoe again, regularly discharge from the filter bottom leakage fluid dram.The filter vat wall has 5 layers of structure being convenient to filter, as long as the filter vat of sufficient amount is set in filter, gas just can obtain fully effectively filtering, and exit gas purifies purity and improves, the follow-up running device that can not stop up or wear and tear can obtain high-quality final products.The utility model filter is particularly useful for as the sour gas filter.

The specific embodiment

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

As Fig. 2, Fig. 3 and shown in Figure 7, on the housing 2 of High-Performance Gas Filter, following two parts are sealedly and fixedly connected by flange 3, housing has air inlet 5, exhaust outlet 1, leakage fluid dram 6, also has the filter of forming by orifice plate 7 and filter vat 8, orifice plate 7 is tightly connected with housing 2, filter vat 8 is corresponding one by one with the hole on the orifice plate 7, bucket wall upper end is connected with pore plate by sealing, bucket wall structure is followed successively by outer band opening supporting mass 81 from outside to inside, outer stainless steel cloth 82, filter core 83, interior stainless steel cloth 84, interior supporting mass 85 with holes, the bucket end, have the interlayer base plate, upper plate 86 is connected with bucket wall inner seal, lower shoe 87 is tightly connected with bucket wall lower end, and lower shoe is tightly connected by pod apertures in the middle of it 871 and the mozzle 9 that leads to the filter housings bottom.Among the embodiment, the supporting mass inside and outside with holes of orifice plate, filter vat is made by metal material, and material for core can be that puffy glass fiber, plastic wire-drawing cellucotton or stainless steel sleave compress filler.

As shown in Figure 4, among the embodiment, the structure that is tightly connected of filter vat and orifice plate is: filter vat 8 upper ends and a cannelure decorative cover 10 are tightly connected (welding and splicing), and cannelure decorative cover 10 is sealedly and fixedly connected by bolt 11 with orifice plate 7 again.This structure that is tightly connected is convenient to the integral replacing filter vat.

As shown in Figure 5, among the embodiment, be equipped with the filter core 12 of stainless steel cloth parcel in filter vat 8 upper and

lower base plate
