DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. 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.

[0030] See also Figure 1-4 The utility model provides a technical solution for a deodorization system for primary processing of rubber: a deodorization system for primary processing of rubber, comprising a deodorization room 1 and an air inlet 2 and an air outlet 3 connected at both ends of the deodorization room 1, the air inlet 2 is connected to the air collecting hood pipe on the rubber processing production line, the air outlet 3 is connected to the external smoke exhaust pipe through the smoke exhaust pipe, the waste gas generated by the rubber processing production line is processed in the deodorization room, and finally discharged into the smoke exhaust pipe through the air outlet 3.

[0031] The interior of the deodorizing room 1 is divided into a cooling spray room 6, an alkali solution spray room 7 and a plant solution spray room 8 by two partition plates 9. A cold water delivery pipe 62, an alkali solution delivery pipe 72 and a plant solution delivery pipe 84 are respectively arranged at the rear side of the deodorizing room 1 corresponding to the cooling spray room 6, the alkali solution spray room 7 and the plant solution spray room 8. One end of the cold water delivery pipe 62, the alkali solution delivery pipe 72 and the plant solution delivery pipe 84 are all provided with a solenoid valve;

[0032] The inner wall, top and side wall of the cooling spray room 6 and the partition plate 9 are all equipped with cold water spray heads 61. The multiple cold water spray heads 61 are connected to the cold water delivery pipe 62 through pipelines. The cold water delivery pipe 62 can deliver clean water to the multiple cold water spray heads 61, and then spray the water into the cooling spray room 6 in the form of mist through the cold water spray heads 61, so as to facilitate the contact cooling of the high-temperature exhaust gas just entering the deodorization room. At the same time, when contacting with the smoke and odor, the impurities contained in the rubber odor can be atomized and precipitated to be removed;

[0033] The inner wall, the top and the side wall of the partition plate 9 of the alkali liquid spray chamber 7 are all installed with alkali liquid spray heads 71. The multiple alkali liquid spray heads 71 ​​are connected to the alkali liquid delivery pipe 72 through pipelines. The cooled exhaust gas will enter the alkali liquid spray chamber 7 through the smoke exhaust grille 10. The alkali liquid is sprayed out by the alkali liquid spray head 71 in an atomized spraying manner and contacts with the rubber odor. Since the rubber odor contains a large amount of acidity, the alkali liquid with a specific value is used for washing, which can degrade the acidic substances in the odor gas, that is, the aerosol in the rubber odor can be processed, and the odor has a cooling effect, and the deacidification removes impurities from the gas again;

[0034] The inner wall, top and side wall of the plant liquid spray chamber 8 and the partition plate 9 are all installed with plant liquid spray heads 81, and the multiple plant liquid spray heads 81 are all connected with the plant liquid delivery pipe 84 through pipelines. A packing plate 82 is also installed inside the plant liquid spray chamber 8, and a water baffle 83 is vertically installed inside the plant liquid spray chamber 8 near the air outlet 3. The water baffle 83 can prevent the sprayed plant liquid from splashing to the air outlet 3. The plant liquid spray chamber 8 adopts the plant liquid spray deodorization principle, and uses the plant liquid spray head 81 to spray in an atomized spraying manner. The effective molecules of the atomized plant liquid are evenly dispersed in the purification space, so that the effective ingredients have the characteristics of strong penetration, large specific surface area, strong adhesion, and large kinetic energy, and undergo chemical reactions such as decomposition, polymerization, substitution, replacement and addition with the odor molecules, and quickly remove the odor molecules, weaken the chemical bonds in the odor molecules, increase the instability of the odor molecules, and prompt the odor molecules to change the original molecules, thereby achieving the odor treatment effect;

[0035] The bottom ends of the two partition plates 9 and the bottom ends of the filler plates 82 are provided with drainage plates 91 for convenient circulation of the spray waste liquid. The top of one partition plate 9 and the top of the filler plate 82, as well as the bottom of the other partition plate 9 are provided with smoke exhaust grilles 10 for convenient circulation of smoke. The inner bottom of the deodorizing room 1 is in an inclined state, and its bottom is inclined to facilitate the waste liquid generated by the spray to flow to the drain port 40 at the bottom of the cooling spray chamber 6, and then flow into the circulation pool 4 from the drain port 40, so as to facilitate the collection and treatment of the waste liquid from the spray;

[0036] A circulation pool 4 for collecting spray waste liquid is arranged at the bottom of the deodorization room 1, a drain port 40 connected with the circulation pool 4 is arranged at the inner bottom of the cooling spray chamber 6, two second vertical partitions 45 are arranged inside the circulation pool 4, and the interior of the circulation pool 4 is divided into a primary sedimentation tank 41, a secondary sedimentation tank 42 and a clean water tank 43 by the two second vertical partitions 45, the primary sedimentation tank 41 is connected with the inner bottom end of the cooling spray chamber 6 through the drain port 40, the inner bottom of the circulation pool 4 is inclined, and the waste liquid enters the primary sedimentation tank 41 through the drain port 40 for sedimentation treatment. When the waste liquid in the circulation pool 4 gradually increases, the supernatant overflowing from the surface of the primary sedimentation tank 41 will flow through the guide pipe 47 above the grid plate 46 into the secondary sedimentation tank 42 for secondary sedimentation treatment. By the same principle, the supernatant overflowing from the upper part of the secondary sedimentation tank 42 will be diverted by another set of guide pipes 47 and discharged into the clean water tank 43, thereby facilitating the recovery of the waste liquid after treatment.

[0037] The upper end of the primary sedimentation tank 41 is also provided with a first vertical partition 44, and the bottom end of the first vertical partition 44 and the upper end of the secondary sedimentation tank 42 are both horizontally installed with a grid plate 46, and a group of guide pipes 47 are installed on the two second vertical partitions 45, and each group of guide pipes 47 is multiple, one end of one group of guide pipes 47 is located above the grid plate 46 inside the primary sedimentation tank 41, and the other end extends to the inner bottom of the secondary sedimentation tank 42, and one end of the other group of guide pipes 47 is located inside the secondary sedimentation tank 42. Above the grid plate 46, the other end extends to the inner bottom of the clean water tank 43. A sewage pipe 5 is also arranged outside the circulation tank 4. The sewage pipe 5 is connected with the inner bottoms of the primary sedimentation tank 41, the secondary sedimentation tank 42 and the clean water tank 43 through branch pipes, and a sewage valve is arranged on the branch pipe. One end of each branch pipe is located inside the primary sedimentation tank 41, the secondary sedimentation tank 42 and the clean water tank 43, and is connected to a sewage pump. The precipitated sludge can be pumped out by the sewage pump and transported to the sewage pipe 5 by the branch pipe for discharge.

[0038] The working principle of the utility model is as follows: when the deodorization system is used to treat the odor generated by the initial processing of rubber, the generated odor will first enter the cooling spray chamber 6 through the air inlet 2, and spray cold water through the cold water spray head 61 to contact and cool the high-temperature exhaust gas that has just entered the deodorization room. At the same time, when it contacts with the smoke and odor, the impurities contained in the rubber odor can be atomized and precipitated to be removed;

[0039] After the initial cooling spraying, the rubber odor will pass through the exhaust grille 10 above the partition plate 9 in the cooling spray chamber 6 and enter the alkali spray chamber 7. The alkali spray head 71 is used to spray the alkali solution, which will contact with the rubber odor, degrading the acidic substances in the odor gas and having a cooling effect on the odor. The deacidification will remove impurities from the gas again.

[0040] Furthermore, the rubber odor after the secondary treatment will enter the plant liquid spray chamber 8 through the smoke exhaust grille 10 below the partition plate in the alkali liquid spray chamber 7, and the rubber odor will be further processed by the plant liquid spray deodorization principle, and the treated rubber odor will be discharged from the air outlet 3;

[0041] When spraying rubber odor, the sprayed waste liquid is discharged from the drainage board 91 at the bottom of the deodorization room 1 into the drainage port 40 at the bottom of the cooling spray chamber 6, and then the waste liquid enters the circulation pool 4 through the drainage port 40 for sedimentation treatment, so that the waste liquid can be further recovered.

[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
