Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, in particular to a dust removal device for a polypropylene spray tower. Background Art

[0002] Polypropylene is a commonly used plastic material. During industrial production and processing, a large amount of dust may be generated. In order to reduce environmental pollution and ensure the safety of the production environment, it is usually necessary to use a spray tower to remove dust from the exhaust gas.

[0003] The existing polypropylene spray tower dust removal device consists of a tower body, an air inlet, an air outlet and a liquid circulation structure, wherein a packing layer is provided in the tower body, and the spray liquid is evenly sprayed on the packing layer through a droplet distributor to form droplets. The airflow containing dust particles enters the spray tower from the air inlet, and the dust adheres to the spray liquid when passing through the packing layer. The purified gas is discharged from the air outlet at the top of the tower body, and the droplets and dust particles accumulated on the packing layer fall into the liquid pool and are supplied to the droplet distributor through the liquid circulation structure for recycling. In this process, dust removal is performed only by relying on the adsorption effect of the packing layer. The packing layer is often blocked by accumulation, which affects the normal flow of the spray liquid and the purified gas, resulting in unsatisfactory dust removal effect, and the packing layer needs to be cleaned frequently, resulting in low dust removal efficiency. When the liquid is extracted, the liquid circulation structure is prone to sucking in dust together, which not only affects the subsequent dust removal effect, but also causes blockage of the circulation structure. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model proposes a polypropylene spray tower dust removal device which has multiple dust removal structures for sequential dust removal step by step, has a long cleaning cycle, can reduce the dust content of circulating liquid, has high dust removal efficiency and good effect.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed in the utility model is: a device for removing dust from a polypropylene spray tower, comprising a tower body, a guide bucket, a baffle, a spray plate, a filler plate, a droplet distributor, an adsorption plate, a hose and a liquid circulation structure, wherein an air inlet and an air outlet are respectively arranged on one side of the lower end and the upper end of the tower body, the guide bucket, the baffle, the spray plate, the filler plate, the droplet distributor and the adsorption plate are sequentially connected and arranged in the tower body from bottom to top, the spray plate is symmetrically connected and arranged on the inner wall of the tower body, the filler plate and the adsorption plate are clamped and arranged in the tower body, the hose is arranged inside the tower body and is located below the guide bucket, the hose is connected with a floating ring near the lower end, and the liquid circulation structure is arranged on one side of the tower body and the upper and lower ends are respectively connected to the droplet distributor and the hose.

[0006] Furthermore, a plurality of baffles are staggeredly arranged in the tower body below the spray plate, and the baffles are arranged to be tilted downward away from one end of the tower body side wall.

[0007] Furthermore, the spray plate is arranged to be inclined downward.

[0008] Furthermore, the adsorption plate is a corrugated plate.

[0009] Furthermore, sealing doors are provided on the side walls of the tower body to match the bottom of the tower body, the filling plate and the adsorption plate respectively.

[0010] Furthermore, the liquid circulation structure includes a circulation pipe, a circulation pump and a water purifier, and the circulation pump and the water purifier are connected to the droplet distributor, the hose and the spray plate through the circulation pipe.

[0011] Furthermore, a fixing buckle matching the circulation pipe is connected to the side wall of the tower body.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] Multiple dust removal structures remove dust step by step in sequence, and the cleaning cycle is long: In this device, the spray plate, filler plate, and adsorption plate can remove dust from the upward-moving airflow step by step in sequence. The dust removal is repeated multiple times and the dust removal effect is good. The dust will first fall to the bottom of the tower body under the action of the spray plate, thereby reducing the amount of dust on the filler plate and the adsorption plate, thereby extending the cleaning cycle of the device, reducing maintenance costs and downtime, and is conducive to improving dust removal efficiency.

[0014] It can reduce the dust content of the circulating liquid: the floating ring cooperates with the weight of the hose itself, so that the lower end of the hose is always in contact with the upper layer of the waste liquid, effectively preventing the dust in the lower layer of the waste liquid from entering the liquid circulation structure. At the same time, the guide bucket can buffer the falling liquid, reduce the impact of the falling liquid on the waste liquid, and then make the dust stably deposited in the lower layer of the waste liquid, so as to reduce the dust content of the circulating liquid.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Combined with Figure 1 , Attachment Figure 2 A device for removing dust from a polypropylene spray tower comprises a tower body 1, a guide bucket 2, a spray plate 3, a filler plate 4, a droplet distributor 5, an adsorption plate 6, a hose 7 and a liquid circulation structure. An air inlet 8 and an air outlet 9 are respectively arranged on one side of the lower end and the upper end of the tower body 1. The guide bucket 2, the spray plate 3, the filler plate 4, the droplet distributor 5 and the adsorption plate 6 are sequentially connected and arranged in the tower body 1 from bottom to top. The spray plate 3 is symmetrically connected and arranged on the inner wall of the tower body 1. The spray plate 3 is tilted downward, so that the liquid sprayed from the spray plate 3 can have a strong impact on the airflow, thereby achieving a good dust removal effect.

[0021] Combined with Figure 1 A plurality of baffles 11 are staggeredly arranged in the tower body 1 below the spray plate 3. The baffles 11 are tilted downward away from one end of the side wall of the tower body 1, which can effectively prevent waste liquid and dust from remaining on the baffles 11 and prevent affecting the subsequent dust removal efficiency.

[0022] Combined with Figure 1 , Attachment Figure 3 The filler plate 4 and the adsorption plate 6 are snap-fitted into the tower body 1. The adsorption plate 6 is a corrugated plate, which is snap-fitted for easy removal, cleaning or replacement. The corrugated plate can increase the contact area with the airflow, thereby achieving sufficient dehumidification and dust removal.

[0023] Combined with Figure 1 , Attachment Figure 2 The side walls of the tower body 1 are respectively matched with the bottom of the tower body 1, the filler plate 4 and the adsorption plate 6 to provide sealing doors 12 for convenient cleaning of the interior of the tower body.

[0024] Combined with Figure 1 , Attachment Figure 2 The hose 7 is arranged inside the tower body 1 and below the guide bucket 2. A floating ring 10 is connected to the hose 7 near the lower end. The liquid circulation structure is arranged on one side of the tower body 1 and the upper and lower ends are respectively connected to the droplet distributor 5 and the hose 7. The liquid circulation structure includes a circulation pipe 13, a circulation pump 14 and a water purifier 15. The circulation pump 14 and the water purifier 15 are connected to the droplet distributor 5, the hose 7 and the spray plate 3 through the circulation pipe 13. A fixing buckle 16 matching the circulation pipe 13 is connected to the side wall of the tower body 1. The floating ring 10 can make the lower end of the hose always located at the upper layer of the waste liquid, thereby reducing the suction of dust deposited in the lower layer of the waste liquid and increasing the purity of the circulating liquid. The water purifier 15 can further clean the liquid involved in the circulation, which can effectively prevent dust from entering the circulation structure and causing blockage.

[0025] The specific implementation mode of the utility model is as follows: the device is connected to an external power supply, an appropriate amount of water is injected into the tower body 1, the circulation pump 14 and the water purifier 15 are turned on, the water enters the circulation pipe 13 from the hose 7, and is sprayed from the spray plate 3 and the droplet distributor 5 after dust removal and purification by the water purifier 15, and the airflow to be treated is introduced from the air inlet 8. The airflow slowly rises under the action of the baffle 11, and enters the packing plate 4 after being rinsed by the liquid sprayed by the spray plate 3. At the same time, the waste liquid after rinsing carries dust and flows through the guide bucket 2 and finally falls on the bottom end of the tower body 1. After the airflow passes through the packing plate 4 for dust removal again, it is dusted and dehumidified again through the adsorption plate 6, and finally discharged from the tower body 1 through the air outlet 9. The dust in the liquid is precipitated in the lower layer. The hose 7 continuously absorbs the relatively clean liquid on the upper layer of the waste liquid under the action of the floating ring 10 into the circulation pipe 13 for circulation, so as to realize continuous dust removal of the airflow. The sealing door 12 is opened regularly to clean the packing plate 4, the dust removal plate and the lower end of the tower body 1.

For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
