2) Two-stage filtration is adopted, and the filtering effect is improved by more than 50% compared with the previous one-stage filtration.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Drawings

Fig. 1 is a schematic diagram of the present invention.

Fig. 2 isbase:Sub>A sectional viewbase:Sub>A-base:Sub>A of fig. 1.

In the figure: the filter comprises a box body 1, a gas inlet 2, a gas outlet 3, a filter element mounting rack 4, a filter element 5, a filter element replacing support 6, a liquid exhausting port 7, a supporting baffle 8, a guide rail plate 9 and a gas distributor 10.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Example 1

As shown in figures 1 and 2, the PTFE box type demister comprises a box body 1, wherein the box body 1 is made of PTFE materials, PTFE hardly reacts with common substances, and the box body has the advantages of acid and alkali corrosion resistance, high and low temperature (-50-200 ℃), good mechanical strength, wide applicable scene and long service life.

1 both ends of box are equipped with gas feed 2 and gas outlet 3 respectively, import and export for the gas, 1 cross section of box be the rectangle, 1 of box in be equipped with two filter core mounting brackets 4 that are parallel to each other, detachable is equipped with a filter core 5 in every filter core mounting bracket 4, be equipped with a filter core change support 6 respectively in every filter core mounting bracket 4 top and be located 1 top of box, every filter core change support 6 corresponds a filter

core mounting bracket

4, and 6 bottoms of filter core change support and box outer wall sealing connection, be equipped with the flange on the filter core change support 6 for the opening of sealed filter core change support 6, open or close the flange, can be used to dismouting filter core 5, 1 bottom of box is equipped with liquid row mouth 7 to the greatest extent.

The utility model discloses, filter core mounting bracket 4, filter core 5, filter core change support 6 etc. adopt the modularized design, and processing, installation are convenient, and expansibility is strong. The box body 1 is of a rectangular structure, and compared with the conventional disc-shaped structure, the box body can be independently installed, relatively occupies small space and saves investment. The interior of the box body 1 is completely communicated, the flux is large, and the resistance is small.

The filter element accessible filter element replacement support 6 flange is directly dismantled and is changed, and convenient and fast saves and maintains the expenditure, and is especially obvious when handling complicated easy stifled gas, prepares two sets of filter cores, can trade the usefulness of using, and the filter core that trades down washs good back regularly again outside equipment, need not shut down, does not influence production.

In this embodiment, as shown in fig. 2, the filter element mounting rack 4 includes two parallel support baffles 8 arranged along the vertical direction, the support baffles 8 are densely provided with small holes, the edge of the support baffle 8 is connected with the inner wall of the box body 1 in a sealing manner, and two parallel guide rail plates 9 arranged along the vertical direction are arranged between the two support baffles 8.

The support baffle 8 and the guide rail plate 9 on each filter element mounting bracket 4 enclose and close to be a rectangular channel for the filter element 5 to insert, and thus the filter element 5 is inserted into the rectangular channel and is detachably connected with the filter element mounting bracket 4.

The box body 1 is also internally provided with a gas distributor 10, and the gas distributor 10 is positioned between the gas inlet 2 and a filter element mounting frame 4 close to the gas inlet 2. The gas distributor 10 is a product available on the market in the prior art, and the gas distributor is arranged at the front end of the filter element, so that the uniform distribution of gas is improved, and the filtering effect can be improved.
