Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waste gas treatment equipment, and particularly to a waste gas treatment chemical spraying device. Background Art
[0002] When treating slaughter sewage, a large amount of waste gas is often generated. If these waste gases are not treated, they will become extremely stinky, which will not only pollute the environment, reduce air quality, but also damage the human respiratory system. Therefore, generally, slaughterhouses will use waste gas treatment equipment in slaughterhouses to treat the corresponding waste gas. Currently, the commonly used treatment method is generally to collect the waste gas first, and then introduce it into a biological deodorization tower and a spray tower for treatment. After treatment with deodorants and other chemicals, it is discharged through a high-altitude exhaust tower.
[0003] Currently, when the spray tower sprays waste gas, it often uses spray heads at fixed positions to spray the chemical mixture into the tower to treat the waste gas entering the spray tower. However, this often causes the chemicals to be unevenly distributed in the spray tower, and there may be spray corners, resulting in a decline in the treatment effect. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a waste gas treatment chemical spraying device to solve the situation that the fixed spray heads cause uneven chemical distribution and reduce the waste gas treatment effect.
[0005] The technical solution adopted by the utility model is: a waste gas treatment chemical spraying device, including a spray tower, a chemical mixing part and a chemical spraying part installed on the spray tower. The chemical mixing part is connected to the chemical spraying part through a first pipeline. The chemical spraying part includes a first bracket installed inside the spray tower and a spraying assembly rotatably connected to the first bracket. The spraying assembly includes a plurality of spraying pipelines connected to the first pipeline, and a plurality of spray heads are installed on each spraying pipeline.
[0006] After adopting the above structure, the following beneficial effects are obtained:
[0007] 1. By setting a plurality of spraying pipelines and installing a plurality of spray heads on the spraying pipelines, the area that can be covered by the chemicals during spraying can be increased, and the generation of spray dead corners can be reduced.
[0008] 2. By rotatably connecting the spraying assembly to the first bracket, the spraying assembly can rotate while spraying, thereby increasing the coverage area of the chemicals during spraying. At the same time, continuous rotation can also ensure that the chemicals in the spray tower are covered more evenly and stably, improving the waste gas treatment effect.
[0009] Preferably, a connector is provided between the spraying pipeline and the first pipeline. The spraying pipeline is fixedly connected to the connector, and the connector is rotatably connected to the first pipeline. The nozzle is installed on the side of the spraying pipeline.
[0010] The water mist is continuously sprayed through the nozzles located on the side of the spraying pipeline. The reaction force during the spraying process is used to push the spraying pipeline to rotate around the first pipeline, thus realizing the function of the pipeline automatically rotating during the spraying process, which is not only efficient but also low-cost.
[0011] Preferably, a first driving component for driving the spraying component to rotate is further provided between the first bracket and the spraying component.
[0012] The first driving component drives the spraying component to rotate while spraying, so that the rotation speed and range of the spraying component can be controlled, effectively improving the uniformity of the spraying of the medicament water mist, and thus improving the waste gas treatment effect.
[0013] Preferably, the first driving component includes a driving motor, a driving disk, a connecting rod, a toothed disk and a gear. The driving disk is installed on the output shaft of the driving motor. One end of the connecting rod is connected to the eccentric position of the driving disk, and the other end of the connecting rod is connected to the toothed disk. The toothed disk is engaged with the gear, and the gear is connected to the spraying component.
[0014] The driving motor drives the driving disk to rotate, so that the connecting rod on the driving disk pushes the toothed disk to rotate reciprocally within a certain range, which can drive the gear to rotate reciprocally within a certain angle, and then drive the spraying pipeline to rotate reciprocally. In this way, each spraying pipeline in the spraying component can be connected to the first pipeline through a hose, reducing the waste of water mist and also preventing the hose from being damaged during the rotation process.
[0015] Preferably, the first driving component is further connected to a driving bracket. The driving bracket is installed on the first bracket, and the spraying component is rotatably connected to the driving bracket.
[0016] The driving bracket can protect and support the first driving component and the spraying component, ensuring that the first driving component and the spraying component can work properly.
[0017] Preferably, the spraying component further includes an annular spraying bracket. The outer ends of the spraying pipelines are connected to the spraying bracket. A second bracket is connected below the first bracket, and a plurality of rollers are provided on the second bracket. The spraying bracket abuts against the rollers.
[0018] The second bracket can support the spraying bracket, preventing the spraying assembly from falling or shaking during long-term operation. At the same time, a number of rollers provided on the second bracket can also reduce the friction during the rotation of the spraying bracket, making the spraying assembly more smooth and stable during rotation.
[0019] Preferably, the chemical mixing part includes a mixing tank and a feeding tank. A number of feeding bins are provided on the feeding tank. A first feeding channel is provided at the bottom of the feeding bin. The bottom of the first feeding channel is communicated with a second feeding channel. One end of the second feeding channel is connected to the mixing tank, and the other end of the second feeding channel is connected to an air compressor.
[0020] A number of feeding bins can store various chemicals. Different chemicals enter the second feeding channel through the first feeding channel and are blown into the mixing tank together with the compressed air released by the air compressor, which can achieve rapid feeding and can mix the chemicals faster.
[0021] Preferably, a screw conveyor mechanism is installed in the first feeding channel.
[0022] The setting of the screw conveyor mechanism can make the feeding amount of the chemical controllable, facilitate the proportioning of the chemical, thereby improving the effect of the chemical on waste gas treatment. At the same time, the screw conveyor mechanism can also prevent the compressed air from blowing the chemical into the feeding bin.
[0023] Preferably, a check valve is further provided at the end of the second feeding channel connected to the mixing tank, and the check valve is located below the liquid level inside the mixing tank.
[0024] Such a setting can make the chemical directly enter the water in the mixing tank and dissolve and mix faster. At the same time, the setting of the check valve can also prevent the water in the mixing tank from entering the second feeding channel while ensuring the smooth entry of the chemical into the mixing tank.

Specific embodiments
[0034] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] Embodiment 1
[0036] As shown in the attached Figures 1-4 drawings, the present utility model provides an exhaust gas treatment chemical agent spraying device, including a spray tower 10 and a chemical agent spraying part installed inside the spray tower 10. A chemical agent mixing part is also installed outside the spray tower 10. The chemical agent mixing part and the chemical agent spraying part are connected by a water pump 55 and a first pipeline 56. The water pump 55 can pressurize the water mixed with the chemical agent and transport it through the first pipeline 56 to the chemical agent spraying part and spray it into the spray tower 10. Among them, the chemical agent spraying part includes a first support 21 and a spraying assembly 30. The first support 21 is fixedly installed inside the spray tower 10. In this embodiment, the spraying assembly 30 includes a cylindrical connecting piece 33 rotatably connected to the bottom end of the first pipeline 56. Five spraying pipelines 31 arranged along the circumferential direction of the connecting piece 33 are connected to the side of the connecting piece 33, and six nozzles 32 are installed on the side of each spraying pipeline 31, and the nozzles 32 are arranged obliquely downward.
[0037] In this embodiment, the agent mixing unit includes a mixing tank 51 and a feed tank 52. Three feed bins 524 are provided on the feed tank 52. A vertically arranged first feed channel 521 is connected to the bottom of each feed bin 524. A horizontally arranged second feed channel 522 is provided at the bottom of the first feed channel 521, and the second feed channel 522 is communicated with each first feed channel 521. A screw conveyor mechanism 523 is installed in each first feed channel 521. The amount of agent powder entering the second feed channel 522 can be controlled through the screw conveyor mechanism 523 to ensure accurate agent proportioning, thereby improving the waste gas treatment effect.
[0038] In this embodiment, one end of the second feed channel 522 is connected to an air compressor 53 for delivering compressed air. The other end of the second feed channel 522 is communicated with the mixing tank 51. Water is filled inside the mixing tank 51. The port where the second feed channel 522 is communicated with the mixing tank 51 is located below the water surface, and a check valve 54 is installed at the port where the second feed channel 522 is connected to the mixing tank 51. When the air compressor 53 delivers high-pressure air into the second feed channel 522, the check valve 54 can be opened, enabling the air to carry the agent dust into the mixing tank 51. When the air compressor 53 stops delivering high-pressure air, the check valve 54 closes to prevent moisture from entering the second feed channel 522.
[0039] Its working principle is that the three feed bins 524 in the feed tank 52 store different types of agents. According to the proportioning requirements, under the pushing action of the screw conveyor mechanism 523, they enter the second feed pipe along the first feed pipe and are blown into the mixing tank 51 under the action of the air flow. After being mixed with the water in the mixing tank 51, they enter the first pipe 56 under the action of the water pump 55 and are sprayed out from the spraying pipe 31. During the spraying of the agent, the spraying pipe 31 receives the reaction force of the agent spraying and starts to rotate, thereby achieving more uniform and comprehensive coverage and reacting with the waste gas entering from the bottom of the spray tower 10 to improve the waste gas treatment efficiency and treatment effect.
[0040] Embodiment 2
[0041] According to the attached instructions Figures 5-8As shown in the figure, the difference between this embodiment and Embodiment 1 is that a first driving component 40 for driving the spraying component 30 to rotate is further installed between the first bracket 21 and the spraying component 30. The first driving component 40 includes a driving bracket 46 and a driving motor 41, a driving disk 42, a connecting rod 43, a gear disk 44 and a gear 45 installed on the driving bracket 46. The driving disk 42 and the driving motor 41 are respectively located on both sides of the driving bracket 46, and the driving disk 42 and the driving motor 41 are connected by a bevel gear 45 group. One end of the connecting rod 43 is rotatably connected to the eccentric position of the driving disk 42, and the other end of the connecting rod 43 is rotatably connected to the gear disk 44. The center of the gear disk 44 is rotatably connected to the driving bracket 46, and the gear disk 44 meshes with the gear 45. The gear 45 is rotatably connected to the central position of the driving bracket 46, and the gear 45 is connected to the spraying component 30.
[0042] By installing the driving motor 41 and other components on both sides of the driving bracket 46 respectively, the space can be utilized more effectively, which is convenient for protecting the transmission structure. At the same time, the installation structure can be made more reasonable, and a more stable supporting effect can be achieved on the first driving component 40.
[0043] In this embodiment, the spraying component 30 includes a cylindrical connecting piece 33 and five spraying pipes 31 fixedly installed on the connecting piece 33. Each spraying pipe 31 is connected to the first pipe 56 through a hose. Eight nozzles 32 are installed at the bottom of each spraying pipe 31, and a spraying bracket 34 is further arranged outside the spraying pipe 31. The spraying bracket 34 is connected to the outer ends of all the spraying pipes 31. The cross section of the spraying bracket 34 is an inverted "L" shape. An "L" - shaped second bracket 47 is further installed below the first bracket 21, and a plurality of rollers 48 are installed on the upper end surface of the horizontal section of the second bracket 47. The lower end surface of the horizontal section of the spraying bracket 34 abuts against the rollers 48, which can not only support the spraying component 30, but also reduce the friction force when the spraying component 30 rotates.
[0044] The working principle is that during spraying, the driving motor 41 drives the driving disk 42 to rotate, thereby driving the connecting rod 43 to push the gear disk 44 to swing around the center of the gear disk 44. During the swinging process of the gear disk 44, the engaged gear 45 is driven to rotate reciprocally within a certain range, so that the spraying component 30 rotates reciprocally. In this way, the spraying pipe 31 and the first pipe 56 can be connected by a hose, and the situation that the hose breaks or separates from the spraying pipe 31 and the first pipe 56 due to the continuous rotation of the spraying pipe 31 will not occur. At the same time, by using a hose connection, the sealing performance between the first pipe 56 and the spraying pipe 31 can be made better, reducing the situation that the pharmaceutical solution leaks out from the gap during spraying, enabling the pharmaceutical solution to contact the waste gas more comprehensively, and thus achieving a better waste gas treatment effect.

The present utility model is not limited to the above embodiments, and its specific structure allows for variations. All variations made within the scope of protection of the independent claims of the present utility model are within the scope of protection of the present utility model.
