Description

Technical Field

[0001] The utility model relates to the technical field of air rectification, in particular to an air pre-treatment filtering and dust removal device. Background Art

[0002] Air distillation is a method of separating air. The process of separating liquid and air by using the difference in boiling points is called distillation. The cryogenic method of air separation is a combination of deep cooling and distillation. It is currently the most widely used air separation method. Air distillation is a processing method based on air. Before air distillation, the outside air needs to be filtered to remove the tiny impurities in the air and avoid affecting the distillation process.

[0003] In the utility model patent with patent publication number CN216879827U, an electrode is set. When in use, the airflow is sent into the groove through the electric fan in the air inlet duct, and then static electricity is generated through the electrode inside the groove. After the static electricity is generated, the dust will fall and then enter the bottom of the groove. Through this setting, the dust in the air is processed to the maximum extent. The limit roller is driven by the motor, so that the limit roller collides with the contact plate, thereby causing the electrode to shake. The process of electrode shaking will shake off the dust attached to the surface of the electrode.

[0004] However, in the related art, although this setting can remove dust from the air, during the shaking process of the electrode, dust may still enter the side of the electrode plate away from the air inlet pipe. Even if the machine is shut down for processing, the dust will still cover the air outlet section. When the machine is started, the dust will also enter the subsequent parts, causing impact.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 5 As shown, the embodiment of the utility model provides an air pre-treatment filtering and dust removal device, which includes a housing 10, a ventilation duct 20 and a spraying member 30. The ventilation duct 20 is arranged in the housing 10, and the ventilation duct 20 includes a first transition section 21 and at least two vertical sections 22. The first transition section 21 is an arc-shaped structure with a downward protrusion in the middle, and the two ends of the first transition section 21 are respectively connected to the lower end of a vertical section 22. The spraying member 30 is arranged on the ventilation duct 20, and the spraying port of the spraying member 30 is connected to the inner cavity of the ventilation duct 20, and the height of the spraying port of the spraying member 30 is higher than that of the first transition section 21.

[0032] When the air pretreatment filtering and dust removal device provided in this embodiment is used, when dust removal is required for the air, the air is first sucked into the ventilation duct 20, and then the inner cavity of the ventilation duct 20 is sprayed by the spraying member 30. The water at the spraying point will contact the dust in the air, that is, the air goes up and the water goes down under the influence of gravity. When the two come into contact, they take away the dust in the air. When the water falls mixed with dust, since the first transition section 21 is an arc-shaped structure with a downward protrusion in the middle, the dust-containing water will gather at the bottom of the first transition section 21. With the above structure, since dust dissolves in water and the dust-containing water will gather at the bottom of the first transition section 21, the dust in the dust-containing water will not return to the air, thereby improving the dust removal effect of the air.

[0033] like Figure 1 As shown, the ventilation duct 20 further includes a second transition section 23, which is an arc-shaped structure with a middle portion convex upward, and both ends of the second transition section 23 are respectively connected to the upper end of a vertical section 22. By providing the second transition section 23, under the cooperation of the second transition section 23 and the first transition section 21, the passage of the ventilation duct 20 is more tortuous, which can further improve the dust removal effect.

[0034] Specifically, the ventilation pipeline 20 in this embodiment includes two first transition sections 21 and one second transition section 23 , and the second transition section 23 is located between the two first transition sections 21 .

[0035] The spraying member 30 is disposed in the middle of the second transition section 23 , so that the spraying position of the spraying member 30 is higher, which is convenient for dust removal.

[0036] like Figure 1 As shown, the air pre-treatment filtering and dust removal device also includes a dust filter 40, which is arranged in the vertical section 22. The dust filter 40 can be used to remove dust from the air again, so that the dust removal effect can be further improved. During operation, the dust in the air is blocked, and as the water above falls, the dust impurities in the dust filter 40 are mixed with the water and fall down.

[0037] Specifically, the side wall of the vertical section 22 has a mounting groove 221 extending therethrough, and the dust filter 40 is mounted at the mounting groove 221 and extends into the vertical section 22.

With the above assembly structure, the dust filter 40 has the advantage of a simple assembly structure.

[0039] In this embodiment, the filter plate 42 is magnetically connected to the mounting plate 41 , and the filter plate 42 and the mounting plate 41 are easy to assemble and disassemble.

[0040] Wherein, each vertical section 22 is provided with a dust filter 40, and the dust filtering effect is good.

[0041] Specifically, the filter holes of the filter plate 42 are conical holes, the purpose of which is to facilitate the removal of the filter plate 42, and at the same time, the filter holes facilitate the rapid downward flow of the mixed water.

[0042] like Figure 1 As shown, the air pretreatment filtering and dust removal device also includes a waste liquid tank 51 and a waste liquid pipe 52. The upper end of the waste liquid pipe 52 is connected to the middle of the first transition section 21, and the lower end of the waste liquid pipe 52 is connected to the waste liquid tank 51. The dust-containing water in the first transition section 21 can enter the waste liquid tank 51 through the waste liquid pipe 52 to collect the dust-containing water.

[0043] Specifically, an inspection door or a drainage pipe is reserved at the front end surface of the waste liquid tank 51 .

[0044] The air pre-treatment filtering and dust removal device further comprises a liquid inlet pipe 60 , the outlet of the liquid inlet pipe 60 is connected with the inlet of the spraying member 30 , and water can enter the spraying member 30 through the liquid inlet pipe 60 and be sprayed out through the spraying member 30 .

[0045] In this embodiment, the spraying member 30 is an atomizing nozzle, which is electrically connected to an external liquid supply device via a liquid inlet pipe 60 .

[0046] like Figure 1 As shown, the air pre-treatment filtering and dust removal device further includes an air guide plate 70, an air inlet 11 is provided on the housing 10, a first end of the air guide plate 70 is connected to the air inlet 11, and a second end of the air guide plate 70 is connected to the inlet of the ventilation duct 20. The air guide plate 70 is used to guide the air entering from the air inlet 11 so that the air enters the ventilation duct 20 smoothly.

[0047] Specifically, a sealing ring is sandwiched between the connection between the air guide plate 70 and the air inlet 11 .

[0048] In this embodiment, an air inlet fan 12 is provided at the air inlet 11 to facilitate external air to enter the ventilation duct 20 .

[0049] The ventilation duct 20 further includes an inlet section 24 and an outlet section 25 extending in the transverse direction, one end of the inlet section 24 is connected to the second end of the air guide plate 70, the other end of the inlet section 24 is connected to the upper end of the vertical section 22 at the head end, one end of the outlet section 25 is connected to the upper end of the vertical section 22 at the tail end, an air outlet is provided on the housing 10, and the other end of the outlet section 25 is connected to the air outlet. By providing the inlet section 24 and the outlet section 25, it is convenient to realize the connection between the ventilation duct 20 and the housing 10.

[0050] In this embodiment, an auxiliary fan is installed inside the air outlet, the purpose of which is to provide auxiliary suction force to prevent the meandering structure (transition section) of the ventilation duct 20 from causing air stagnation.

[0051] Specifically, the air outlet is communicated with the rectification air inlet mechanism.

[0052] In this embodiment, the ventilation pipeline 20 is a hollow plate-shaped structure, which has the advantages of simple structure and low cost.

[0053] The device provided by this embodiment has the following beneficial effects:

[0054] (1) The outside air is sucked into the ventilation duct 20 through the exhaust fan (inlet fan 12), the dust in the air is blocked by the filter plate, and the atomizing nozzle draws water through the external liquid supply device to form an atomized spray. The water molecule structure in the atomized water is in relative contact with the dust in the air, that is, the air goes up and the atomized water goes down under the influence of gravity. When the two come into contact, they take away the dust in the air. When the atomized water falls mixed with dust, since the first transition section is a semicircular structure, the dust-containing water will gather at the bottom of the first transition section and flow into the waste liquid tank through the waste liquid pipe for collection and treatment.

[0055] (2) The mounting plate is inserted into the mounting groove, the bolts are inserted into the mounting holes of the mounting plate, and nuts engaged with the bolts are screwed into the back of the side plate to fix the mounting plate, which makes it more convenient to replace the filter plate.
