Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for leather recycling. Background Art

[0002] When leather is recycled, it goes through the stages of waste leather storage treatment, light separation, sorting, chemical treatment and dehairing effect confirmation. These stages will produce different waste gases, which will pose a great threat to the environment and human health. Therefore, waste gases need to be treated during the leather recycling process to protect the environment and human health.

[0003] Publication No. CN 212974631 U discloses a waste gas purification device for leather production. The waste gas purification device for leather production, through the design of a mounting plate, an induced draft fan, an exhaust pipe, a water tank, a filter screen and an exhaust pipe, can facilitate timely discharge and purification of waste gas during leather production. At the same time, the glass fiber filter layer, the non-woven fabric filter layer and the activated carbon filter layer arranged in the filter screen can effectively sterilize and filter the waste gas so that the waste gas meets the emission standards, thereby avoiding the situation where the working environment is polluted by the waste gas and improving the protection of the working environment.

[0004] When the exhaust gas discharged from the exhaust pipe in the above-mentioned prior art is discharged into the purification liquid, the bubbles formed are relatively large, resulting in that only the gas around the bubble is in contact with the purification liquid, while the gas in the middle of the bubble is not in contact with the purification liquid, resulting in most of the gas not being treated by the purification liquid, and the exhaust gas treatment effect is poor. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In view of this, the purpose of the utility model is to propose a waste gas treatment device for leather recycling. The technical problem to be solved is that when the waste gas discharged from the exhaust pipe is discharged into the purified liquid, the bubbles formed are relatively large, resulting in only the gas around the bubble being in contact with the purified liquid, while the gas in the middle of the bubble is not in contact with the purified liquid, resulting in most of the gas not being treated by the purified liquid, and the waste gas treatment effect is poor.

[0007] (II) Technical solution

[0010] Preferably, the plurality of branch air ducts are distributed at equal intervals in the radial direction of the main air duct, and the plurality of transverse air ducts are distributed at equal intervals in the radial direction of the air collecting plate.

[0017] 2: When the gas enters the gas collecting bin from the branch air pipe, it will blow the fan blades, thereby driving the vertical air pipe to rotate.

It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure.

[0027] Reference Figure 1-6 :

[0028] The utility model provides a waste gas treatment device for leather recycling, comprising a treatment tank 1, a main air duct 2 is fixed at the bottom of the treatment tank 1, a plurality of branch air ducts 3 are fixed and connected to the outside of the main air duct 2, one end of the branch air duct 3 away from the main air duct 2 is fixed and connected to a gas collecting bin 4, a vertical air pipe 6 is sealed and rotatably connected in the gas collecting bin 4, a gas collecting plate 7 is fixed and connected to the top of the vertical air pipe 6, a plurality of transverse air pipes 8 are fixed and connected to the outside of the gas collecting plate 7, and a plurality of air holes 9 are opened on the transverse air pipe 8, an air guide component is arranged between the gas collecting bin 4 and the vertical air pipe 6, and a driving component for driving the transverse air pipe 8 to rotate is also arranged in the gas collecting bin 4, a plurality of branch air pipes 3 are evenly spaced along the radial direction of the main air duct 2, and a plurality of transverse air pipes 8 are evenly spaced along the radial direction of the gas collecting plate 7.

[0029] When in use, the waste gas generated by the leather recycling process is transported to the branch air duct 3 through the main air duct 2, the waste gas is transported to the air collecting bin 4 in the branch air duct 3, and then the waste gas is transported from the air collecting bin 4 to the circular air duct 5, and then from the circular air duct 5 to the vertical air duct 6, and then from the vertical air duct 6 to the air collecting plate 7, and finally from the air collecting plate 7 to the transverse air duct 8, and then discharged from the air hole 9 into the purified liquid in the main air duct 2. By setting a plurality of transverse air pipes 8 and opening a plurality of air holes 9 on the transverse air pipe 8, the bubbles of waste gas discharged into the purified liquid are very small. By converting large bubbles into a plurality of small bubbles, the contact area between the gas and the purified liquid is increased, so that the waste gas can be better treated.

[0030] In addition, the air guide component includes a circular air pipe 5 fixed and connected to the air collecting bin 4, and the end of the circular air pipe 5 away from the air collecting bin 4 is sealed and rotated with the bottom of the vertical air pipe 6, and the circular air pipe 5 and the vertical air pipe 6 are connected, and the driving component includes a plurality of fan blades 10 fixed at equal intervals on the outside of the vertical air pipe 6, and the fan blades 10 are located in the air collecting bin 4.

[0031] It should be noted that when the gas enters the gas collecting bin 4 from the branch air pipe 3, it will blow the fan blades 10, thereby driving the vertical air pipe 6 to rotate. When the vertical air pipe 6 rotates, it drives the gas collecting plate 7 and the transverse air pipe 8 to rotate. When the transverse air pipe 8 rotates, the bubbles discharged from the air hole 9 are not on a vertical line. If the transverse air pipe 8 is stationary, the multiple bubbles discharged from the air hole 9 gradually rise on a vertical line. If these bubbles are numerous and dense, some of the bubbles will merge with each other when floating and rising in the purified liquid, causing the bubbles to increase, and the gas treatment effect is not ideal. The rotation of the transverse air pipe 8 makes the bubbles discharged from the air hole 9 not on a vertical line, so the rising paths of the bubbles will not intersect, thus avoiding the fusion of the bubbles, that is, avoiding the generation of large bubbles, thereby making the exhaust gas better treated.

[0032] In addition, an exhaust pipe 11 is fixed to the top of the treatment tank 1 and connected to it. A filter cartridge 12 is placed in the exhaust pipe 11, and activated carbon particles 13 are laid in the filter cartridge 12. An annular plate 14 is fixed to the top of the filter cartridge 12, and the outer diameter of the annular plate 14 is larger than the outer diameter of the exhaust pipe 11.

[0033] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
