Description

Technical Field

[0001] The utility model relates to the field of gas purification, in particular to a gas purification device. Background Art

[0002] In fields with high requirements for gas cleanliness, ordinary filtration settings cannot meet the needs. However, if multiple layers of filtration equipment are set up, through layer-by-layer filtration, the corresponding requirements can be met. However, layer-by-layer filtration results in slow emergence of clean gas, too little purified gas emerging per unit time, and the quantity of purified gas not meeting the needs either.

[0003] Therefore, how to fully filter the mixed gas so that the supply of clean gas can meet the requirements simultaneously is a problem to be solved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a gas purification device, which solves the problem of insufficient filtration of mixed gas.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] The utility model provides a gas purification device, including a box body and a filter. It is characterized in that an air outlet and an air inlet are respectively arranged at the upper and lower ends of the box body;

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0026] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] As Figure 1 and Figure 2 and Figure 3 shown, it includes a box body 1 and a filter 2. The filter 2 is arranged inside the box body 1. An air outlet 11 and an air inlet 12 are respectively arranged at the upper and lower ends of the box body 1. The clean gas enters from the air inlet 12 and exits from the air outlet 11.

[0028] A fan 3 is arranged inside the box body 1. The air inlet end of the fan 3 is butted against the air inlet 12. When the fan 3 is started, the fan 3 sucks air from the air inlet 12. The filter 2 is located above the fan 3. A duct 4 is arranged at the outlet end of the fan 3. The duct 4 is gradually enlarged from the air inlet end to the air outlet end, that is, the air inlet end of the duct 4 is smaller in size than the air outlet end.

[0029] The air outlet end of the duct 4 is aligned with the mesh holes of a plurality of filters 2. In this way, the gas per unit volume passes through a plurality of filters 2 at the same time, which is equivalent to increasing the gas filtration area.

[0030] A plurality of filters 2 are arranged obliquely, and the high and low ends of adjacent filters 2 are connected, that is, adjacent filters 2 are in a V shape or an inverted V shape to adapt to the rising characteristics of the gas.

[0031] The filter 2 is located below the air outlet 11, and the clean gas coming out of the filter 2 exits from the air outlet 11.

[0032] A filter screen 5 is arranged on the air inlet 12. The mesh holes of the filter screen 5 are larger than those of the filter 2. In this way, the mixed gas passing through the filter screen 5 is primarily filtered, and the large dust particles in the mixed gas are filtered out to prevent the large dust particles from falling into the fan 3 and accumulating too much to affect the operation of the fan 3. The small dust particles in the mixed gas are fully filtered by the filter 2. The mesh of the filter screen 5 and the mesh holes of the filter 2 are slowly filled with dust particles. In this way, the mesh of the filter screen 5 and the mesh holes of the filter 2 become smaller synchronously, and then the air intake and air outlet of the fan 3 are balanced.

[0033] If the mesh holes of the filter screen 5 are the same size as those of the filter 2, then the mesh holes on the filter screen 5 will become smaller and smaller due to the accumulation of dust particles. The air suction of the fan 3 will become less and less, the re-filtering effect of the filter 2 will be poor, and the replacement frequency of the filter screen 5 will be high.

[0034] A sealing frame 6 is arranged inside the box body 1. The sealing frame 6 is located between the filter 2 and the fan 3. The middle of the sealing frame 6 is empty, and the sealing frame 6 is hermetically connected to the inner wall of the box body 1. In this way, the inside of the box body 1 is divided into two upper and lower sealed spaces by the sealing frame 6.

[0035] The filter 2 is arranged on the sealing frame 6. The two sides of the multiple filters 2 are lapped on the upper surface of the sealing frame 6 at the bottom. The sealing frame 6 divides the box body 1 into two upper and lower sealed spaces.

[0036] An inspection opening 7 is also arranged on the box body 1. The inspection opening 7 is aligned with the filter 2. Through the inspection opening 7, the filter 2 can be replaced or maintained. A cover plate 8 is movably arranged on the inspection opening 7. The cover plate 8 has two states: opening and closing the inspection opening 7. When the filter 2 needs to be replaced or maintained, the cover plate 8 is opened. When the filter 2 does not need to be replaced or maintained, the cover plate 8 is closed on the inspection opening 7.

[0037] The air outlet 11 is inclined and arranged at the top end of the box body 1. The inclined air outlet 11 can increase the area for the clean gas to go out.

[0038] Furthermore, a longitudinal louver 13 and a transverse louver 14 are rotatably arranged on the air outlet 11. The longitudinal louver 13 is located above the transverse louver 14. The longitudinal louver 13 and the transverse louver 14 are arranged in a crisscross manner. In order to change the direction of the flowing clean gas, the longitudinal louver 13 and the transverse louver 14 can be rotated. When there is no clean gas flowing out, by rotating the longitudinal louver 13 and the transverse louver 14, the air outlet 11 can be covered to prevent foreign objects from falling into the inside of the box body 1.

[0039] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
