The first cavity 3 and the second cavity 4 are convenient for toxic and harmful gas in the pipeline to gather into the cavities and filter through the filter paper 5. The first shell 1 and the second shell 2 are made of metal materials, and the filter paper 5 covers and is arranged between the first shell 1 and the second shell 2 at intervals, so that the filter paper 5 can be effectively protected from being damaged, and the filtering capacity of the filter is ensured. Because the first shell 1 and the second shell 2 have the same structure, the filter can be installed at will when in use without considering the installation direction, thereby ensuring that the filter is more convenient to install. In practical use, the hard pipe joint and the shell are welded together by adopting a full-welding process, so that the hard pipe joint and the shell are hermetically connected; therefore, different hard pipe joints can be welded according to different pipelines, and the manufacturing is simple and convenient. The first hard pipe joint 6, the first cavity 3, the second cavity 4 and the second hard pipe joint 7 form a passage, so when the filter paper is used, poisonous and harmful gas can enter the first cavity 3 through the first hard pipe joint 6, passes through the second cavity 4 and the second hard pipe joint 7 after being filtered by the filter paper 5, flows into the downstream through the second hard pipe joint 7, or flows into the downstream from the second hard pipe joint 7 and flows out from the first hard pipe joint 6, and the filtration of the poisonous and harmful gas is realized.
Preferably, the first shell 1 further comprises a first reducing flange 8, and the first reducing flange 8 is wrapped outside the first cavity 3; the first reducing flange 8 comprises a first opening 10 and a second opening 11 which are opposite, and the first hard pipe joint 6 is connected with the first opening 10 in a sealing mode; the second shell 2 comprises a second reducing flange 9, the second reducing flange 9 is wrapped outside the second cavity 4, the second reducing flange 9 comprises a third opening 12 and a fourth opening 13 which are opposite to each other, the second hard pipe joint 7 is connected with the third opening 12 in a sealing mode, and the first reducing flange 8 is identical to the second reducing flange 9 in structure.

Adopt first reducing flange 8 and second reducing flange 9, the little open end and the hard tube coupling with reducing flange are connected, the butt joint of these two big open ends of second opening 11 and fourth opening 13, the area of filter paper 5 is not less than the bore of second opening 11 and fourth opening 13, use through reducing flange, the effective filtration area of filter paper 5 has been increased, thereby improve filtration efficiency, reducing flange is the metal material simultaneously, hard wear-resisting corrosion-resistant, can effectively protect filter paper 5 can't be destroyed as the shell.
Preferably, a high-strength adhesive glue 14 is coated between the second opening 11, the filter paper 5 and the fourth opening 13. The filter paper 5 is sealed in the two reducing flanges by using the high-strength adhesive glue 14, so that the filter paper is simple and convenient to install and has a good sealing effect. Furthermore, the high-strength adhesive 14 is AB glue, so that metal can be effectively adhered and fixed, disconnection of the joint is avoided, and the cost is low.
Utilize fixed reducing flange of glue and filter paper 5, fixed simple and convenient on the one hand, on the other hand can effectively fill in the concatenation department of first reducing flange 8 and second reducing flange 9 to can play good sealed effect when fixed, avoid two reducing flange concatenations department to reveal poisonous and harmful gas.
The reason why the invention uses glue for fixing is that the invention has small volume, and the adoption of screws and the like for fixing not only causes troublesome operation, but also easily causes the breakage of the shell such as a flange and the like, increases the breakage rate of the shell, reduces the production efficiency and improves the product cost. Simultaneously, one screw screwing operation is complicated, so that the problems can be effectively avoided by using glue for fixation, and the operation is simple and convenient.
Preferably, the outer side of the joint of the second opening 11 and the fourth opening 13 is coated with sealing glue. Sealing glue is also coated on the outer side of the joint of the second opening 11 and the fourth opening 13, so that the sealing effect can be further achieved, meanwhile, air leakage caused by the fact that the outer edge of the joint is cracked due to the fact that the micro pipeline filter is exposed in the air or corroded by the external environment when the micro pipeline filter is outdoors is prevented, and a good protection effect is achieved.
In addition, when the filtering effect of the micro pipeline filter is reduced, the glue can be dissolved by the glue dissolving agent, so that the shell of the micro pipeline filter can be directly opened, the filter paper 5 is replaced, and then the micro pipeline filter is fixed and sealed by the glue, and the operation is simple and convenient.

Preferably, the filtering particle size of the filter paper 5 is less than 0.3 micron, which can effectively filter 0.3 micron particles, and the filtering efficiency is above 99.999%.
Preferably, a second filter layer 15 is also provided in each of the first cavity 3 and the second cavity 4. The setting of second filter layer 15 can further improve miniature pipeline filter's filtration efficiency, simultaneously because the increase of the number of filter layers, can effectively prolong the live time of filter, reduced filter paper 5 and changed the frequency to the maintenance cost has been reduced.
Preferably, the second filter layer 15 is fixed removably in the corresponding first and second cavities 3, 4 in a zigzag shape. The zigzag second filter layer 15 can further increase the filter area on the premise of not blocking the first cavity 3 and the second cavity 4, ensure that gas can smoothly circulate while being filtered, and avoid that the gas pressure in the pipeline is increased due to overhigh density of the filter, so that the service life of the pipeline is shortened due to overlarge pressure. Therefore, the zigzag second filter layer 15 can improve the filtering effect and prolong the service life of the filter, and simultaneously has good gas transmission effect. Meanwhile, the second filter layer 15 is detachably fixed in the cavity, so that the filter layer can be replaced by directly opening the filter when the second filter layer 15 loses the filtering effect, and the integral recycling of the micro pipeline filter is realized.
The zigzag second filter layer 15 is approximately parallel to the filter paper 5, so that harmful gas sequentially passes through each folded surface of the zigzag second filter layer 15 when being filtered by the second filter layer, and the gas is filtered by multiple layers, thereby not only improving the filtering efficiency, but also improving the filtering precision of the filter.
As shown in fig. 3, preferably, the second filter layer 15 is a detachable chevron structure, the second filter layer 15 is formed by folding a filter sheet and includes an inlet 17, the inlet 17 of the second filter layer 15 located in the first cavity 3 is butted against the first opening 10, and the inlet 17 of the second filter layer 15 located in the second cavity 4 is butted against the third opening 12.
The second filter layer 15 of the chevron structure is perpendicular to the filter paper 5, the opening of the second filter layer is butted with the inlet 17 of the filter, so that when gas enters the filter from the first opening 10 or the third opening 12, the gas directly enters the second filter layer 15 of the chevron structure and passes through the second filter layer 15 after being filtered to flow to the filter paper 5, the second filter layer 15 of the chevron structure greatly increases the filtering area, the filtering is more sufficient, and the filtering speed is very high. At this moment, two second filter layers 15 in the filter and filter paper 5 cooperate to form 3-component filtration, which can ensure high-speed filtration and better filtration precision.
Preferably, the surface of the second filter layer 15 is a wave-shaped folding structure 16, which can further increase the effective filtering area of the second filter layer 15 and further prolong the service life of the filter; meanwhile, the wave-shaped folding structure 16 can effectively increase the roughness of the surface of the second filter layer 15, and is more convenient for particles to attach to the surface of the second filter layer.
In addition, the filter paper 5 also adopts the wave-shaped folding structure 16, so that the effective filtering area of the filter paper 5 is increased. Meanwhile, the periphery of the filter paper 5 is hermetically connected with the inner side walls of the second opening 11 and the fourth opening 13, so that gas is prevented from flowing out of the filter without being filtered.
It should be noted that, there is a gap between the second filter layer 15 and the inner side wall of the first cavity 3 and the second cavity 4, so that most of particles with high active ingredients can be intercepted first by the second filter layer 15, and then the remaining particles which are not filtered are filtered by the filter paper 5, so as to avoid that the whole filter loses filtering capability after the second filter layer 15 loses filtering capability, and the filter can be opened and the second filter layer 15 and the filter paper 5 can be replaced until the second filter layer 15 and the filter paper 5 have no filtering capability.
When the micro pipeline filter is used, the first hard pipe joint 6 and the second hard pipe joint 7 are respectively and correspondingly connected in a pipeline, then gas flows into the micro pipeline filter from one end, wherein for example, the gas flows into the micro pipeline filter from the first hard pipe joint 6, toxic and harmful gas flows in from the first hard pipe joint 6, is filtered by the second filter layer 15 in the first cavity 3, then flows through the filter paper 5, passes through the filter paper 5, then passes through the second filter layer 15 in the second cavity 4, then flows out from the second hard pipe joint 7 and enters the pipeline, so that particles with high active ingredients can be intercepted in the micro pipeline filter, and clean air continuously flows.
From the above, the micro pipeline filter disclosed by the invention is simple in manufacturing process, only needs partial welding and gluing processes, is few in raw materials, does not need a sealing element, is high in large-scale production efficiency, can be directly connected to a pipeline by a self-contained pipe joint, is simple and convenient to use, is low in manufacturing cost, and almost only needs to consider the cost of a shell. But the filter is very effective for gas filtration, has large filtration area and low resistance, and can protect equipment, personnel and environment safety when being matched with a pipeline of harmful gas. Meanwhile, the second filter layer is arranged, so that the filtering area can be further increased, the filtering effect is improved, the service life of the filter is effectively prolonged, the replacement frequency of a filter element of the filter is reduced, and the cost of workers for maintaining the pipeline is also reduced; the glue sealing is adopted, so that the installation and the sealing are convenient, and the disassembly operation can be completed simply and conveniently by only using the debonding agent; the surface of the second filter layer is wavy, so that the filtering area is further enlarged, the roughness of the surface of the second filter layer is improved, attachment of particles is facilitated, and active particles are filtered out more quickly.
