Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a uniform dispersion device for PAO aerosol. Background Art

[0002] Air purification equipment is usually used for terminal filtration in clean workshops, clean rooms, and dust-free workshops. It is mainly used to filter some dust particles. It is an important equipment to ensure that clean rooms and dust-free workshops can reach the required cleanliness level. Generally speaking, filters are mainly used in air purification equipment to filter air. Filters are also the core components of the entire purification equipment, and are also important components that affect the purification effect and production cost of the purification equipment.

[0003] Among them, aerosol is one of the main substances that the filter needs to purify and absorb. Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium. The uniformity of aerosol passing through the filter has a great influence on the value of filtration efficiency. If the aerosol is concentrated at a certain point and passes through the filter, the upstream and downstream concentration deviation caused by the uneven distribution of aerosol before and after passing through the filter will cause a serious decrease in filtration efficiency. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1-4 As shown, the PAO aerosol uniform dispersion device of the utility model comprises three main parts: a dust hood shell 1, an aerosol inlet pipe 2 and a flow balancing layer 3; the dust hood shell 1 is installed on the air purification device, and the dust hood shell 1 is located on the air inlet side of the filter 200 of the air purification device 100; the aerosol inlet pipe 2 is installed inside the dust hood shell 1, and the aerosol inlet pipe 2 is coiled in the shape of a "mosquito coil", and a plurality of air outlet holes 20 are provided on the aerosol inlet pipe 2, and the plurality of air outlet holes 20 are arranged on the outer wall of the aerosol inlet pipe 2 on the side opposite to the flow balancing layer 3, and the plurality of air outlet holes 20 are evenly spaced on the aerosol inlet pipe 2; the flow balancing layer 3 is arranged in a plurality of layers, and the flow balancing layer 3 is located between the aerosol inlet pipe 2 and the filter, the gas blown out of the air outlet holes 20 flows to the flow balancing layer 3, and the flow balancing layer 3 is used to disperse the gas onto the filter 200.

[0025] Reference Figure 2 The arrow B shown points to the flow direction of the aerosol flowing out of the aerosol inlet tube 2, that is, the aerosol enters the filter 200 after being evenly dispersed through the flow balancing layer 3 from the aerosol inlet tube 2, so that the filter 200 can fully purify the dispersed aerosol.

[0026] Reference Figure 4 As shown, the end of the aerosol inlet pipe 2 located outside the disc is the air inlet end 21, and the end of the aerosol inlet pipe 2 located in the center of the disc is the air outlet end 22. The air inlet end 21 is connected to an air inlet pipe 4, and the end of the air inlet pipe 4 away from the aerosol inlet pipe 2 extends out of the dust hood housing 1, and the end of the air inlet pipe 4 extending out of the dust hood housing 1 is provided with an airtight joint 5.

[0027] Reference Figure 3 As shown, the plurality of flow balancing layers 3 are arranged in parallel, and the flow balancing layer 3 is parallel to the disc surface of the aerosol inlet tube 2. The flow balancing layer 3 includes a plurality of flow balancing panels 31, the plurality of flow balancing panels 31 are located in the same plane, and the plurality of flow balancing panels 31 are arranged in parallel, and the plane where the plurality of flow balancing panels 31 are located is parallel to the disc surface of the aerosol inlet tube 2.

[0028] In the above structure, the flow balancing plate 31 is in a V-shaped plate shape, and one end of the pointed corner of the flow balancing plate 31 is arranged toward the aerosol inlet tube 2, and the V-shaped opening end of the flow balancing plate 31 is arranged toward the filter. A plurality of parallel flow balancing layers 3 are arranged along the aerosol flow direction, and the number of flow balancing plates 31 in the latter layer of the flow balancing layer 3 is greater than the number of flow balancing plates 31 in the former layer of the flow balancing layer 3, so that the plurality of parallel flow balancing layers 3 are arranged in a pyramid shape. The V-shaped edge of the flow balancing plate 31 close to the filter side is on the extended line of the tangent of the V-shaped edge of the flow balancing plate 31 adjacent to the aerosol inlet tube 2, that is, along the Figure 3 The direction of the arrow A in the middle. Such an arrangement allows the aerosol to "run" along the tangent part of the flow balancing plate 31, and finally collide with each other, so that the aerosol is dispersed evenly.

[0029] Preferably, the flow balancing plate 31 is a right-angle plate. In this case, the two right-angled sides of the flow balancing plate 31 are arranged vertically, and the aerosol first collides with the tip of the flow balancing plate 31, and then flows to both sides along the two right-angled sides and flows to the next layer of the flow balancing layer 3. Since the right-angled sides of the flow balancing plate 31 of the next layer are located on the tangent extension line of the flow balancing plate 31 of the previous layer, the aerosol is dispersed again after the collision of the flow balancing plate 31.

[0030] In the above structure, a fixed tube 11 is provided on the inner wall of the dust hood shell 1, and the aerosol inlet tube 2 is arranged on the fixed tube 11. The aerosol inlet tube 2 is welded to the fixed tube so that the aerosol inlet tube 2 can work smoothly and effectively. The dust hood shell 1 includes a bottom plate 12 and four side plates 13. The bottom plate 12 is a square flat plate, and one end of the four side plates 13 is connected to the bottom plate 12. The four side plates 13 are arranged in an outward expansion type along the airflow direction of the aerosol inlet tube 2. A circular opening is provided on the bottom plate 12, and a circular sealing plate 6 is provided at the position of the circular opening. The circular sealing plate 6 seals the circular opening position, and the components in the dust hood shell 1 can be easily inspected and repaired by opening the circular sealing plate 6.

[0031] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
