Although a nozzle is used to spray water to purify the waste gas, it is difficult for the nozzle to completely cover the waste gas during use, and the internal waste gas lacks fluidity, which can easily lead to poor dust removal effects and affect work efficiency. Utility Model Content

[0004] Based on this, it is necessary to provide a waste gas spray device for oil production to address the problem of insufficient spray coverage area. The position of the nozzle can be adjusted in a rotating manner to ensure that the area where the nozzle sprays water can cover the area where the exhaust gas flows, thereby realizing comprehensive and directional water spraying operations to achieve the best dust removal effect.

[0023] like Figure 1-Figure 3 As shown,

[0024] As an optional embodiment,

[0025] An exhaust gas spraying device for oil production comprises a spray tower body 1, an air inlet pipe 2 is installed on the side of the spray tower body 1, an exhaust pipe 3 is installed on the top of the spray tower body 1, and a spray assembly for cleaning the exhaust gas is installed inside the spray tower body 1;

[0026] The spray assembly includes a mounting frame 4 rotatably connected to the inner wall of the spray tower body 1, a spray head 5 is installed at the bottom of the mounting frame 4, a rack 6 is installed on the mounting frame 4, a connecting rod 8 is inserted into the inner wall of the spray tower body 1, the connecting rod 8 is rotatably connected to the spray tower body 1, a gear 7 meshing with the rack 6 is installed at one end of the connecting rod 8, a motor 12 is installed on the outer wall of the spray tower body 1, a synchronous wheel 10 is installed on one end of the connecting rod 8 and the rotating shaft of the motor 12, and a synchronous belt 11 is connected between the two synchronous wheels 10.

[0027] In the above structure, the rack 6 is an arc rack and is fixed on the mounting frame 4. The center of the arc rack is at the center of the mounting frame 4. The mounting frame 4 can be horizontally mounted on the inner wall of the spray tower body 1 through a bearing seat. The rack 6 is subsequently meshed with the gear 7, which drives the mounting frame 4 to rotate inside the spray tower body 1. The rack 6 is supported on the spray tower body 1 through a connecting rod 8. The connecting rod 8 is horizontally inserted on the side wall of the spray tower body 1, and the connecting rod 8 is above the mounting frame 4. At the same time, the connection between the connecting rod 8 and the spray tower body 1 is a rotation connection;

[0028] Then, the air inlet pipe 2 is connected to the waste gas pipeline outside, so that the waste gas to be treated is passed into the spray tower body 1 for spray treatment. After the waste gas enters the spray tower body 1, it is gradually discharged to the exhaust pipe 3 installed on the top of the spray tower body 1. The spray assembly arranged at the waste gas flow area of ​​the spray tower body 1 is used to clean the particulate matter in the waste gas to reduce the dust content in the waste gas. At the same time, some industrial waste gas that can be dissolved in water can also be washed;

[0029] A plurality of nozzles 5 can be installed at the bottom of the mounting frame 4 to spray water in different areas, but the areas between the nozzles 5 cannot be covered. Based on this, a linkage structure is designed to drive the mounting frame 4 to rotate inside the spray tower body 1, specifically as follows: mutually meshing gears 7 and racks 6 are designed. The racks 6 can be arc-shaped racks and are distributed in a circular shape on the top of the mounting frame 4. The gears 7 are supported on the side walls of the spray tower body 1 through connecting rods 8, and a motor 12 is fixedly installed on the surface of the spray tower body 1. The motor 12 is used to drive the connecting rod 8 to rotate on the spray tower body 1. The motor 12 and the connecting rod 8 are both By installing the synchronous wheel 10 and putting a synchronous belt 11 on the two synchronous wheels 10, the motor 12 can drive the gear 7 to rotate, and then the gear 7 drives the rack 6 and the mounting frame 4 connected to the rack 6 to rotate horizontally inside the spray tower body 1. When the mounting frame 4 rotates horizontally, the nozzle 5 located on the mounting frame 4 can be driven to rotate as a whole, so that the exhaust gas can be fully contacted with the spray while the internal exhaust gas flow is increased by rotation. At the same time, the rotation of the nozzle 5 itself can effectively change the position of the nozzle 5 itself, so as to realize all-round spraying operation and avoid the problem of uneven spraying or incomplete coverage during the water spraying process of the nozzle 5.

[0030] As a further preferred solution, a water pump 14 is installed on the surface of the spray tower body 1. The drainage end of the water pump 14 is connected to the interior of the spray tower body 1 through a first pipe fitting and then connected to the mounting frame 4. The drainage end of the water pump 14 is connected to the drainage pipe of the spray tower body 1 through a second pipe fitting.

[0031] The water pump 14 draws the water stored at the bottom of the spray tower body 1 into itself through the second pipe fitting, and enters the water from the first pipe fitting at the discharge end of the water pump 14 to the various nozzles 5 under the mounting frame 4 for spraying, thereby realizing a circulating spraying operation. Subsequently, it is only necessary to replace the water regularly. When replacing the water, the valve of the drainage pipe is opened to drain the water stored inside the spray tower body 1, and then water is injected into the interior through the drainage pipe, and then the valve of the drainage pipe is closed. In this way, it is only necessary to change the water regularly. When there is no need to change the water, it is only necessary to control the start and stop of the water pump 14 to realize the spraying operation, which is convenient to operate.

[0032] Furthermore, two spray assemblies are provided, and a swirl air guide plate 16 is horizontally installed in the gap between the two spray assemblies. After the spray assembly sprays water, the water sprayed collides with the swirl air guide plate 16 and rebounds or splashes again, thereby changing the original spraying direction. At the same time, the swirl air guide plate 16 causes the airflow to swirl around the tower wall through the swirl air guide plate 16, and the water sprayed downward also swirls around the tower wall at the same time. The airflow runs upward along the tower wall, which increases the running length, increases the contact time between dust and water, and achieves uniform washing.

[0033] Furthermore, a first pipe fitting is connected to the mounting frame 4 in the two spray assemblies, and the two first pipe fittings are connected to the drainage end of the water pump 14 through a tee pipe. A solenoid valve 15 is installed on each of the first pipe fittings. The purpose of installing the solenoid valve 15 is to control whether the corresponding spray assembly carries out the spraying operation and adjust the opening number of the spray assembly as needed.

[0034] A guide plate 17 is installed inside the spray tower body 1 and below the swirl guide plate 16. A mounting groove 171 is opened at the bottom center of the guide plate 17. A filter plate assembly for filtering exhaust gas is arranged in the mounting groove 171. The guide plate 17 collects water on the inner wall of the spray tower body 1, and after being filtered by the filter plate assembly, it enters the water storage space at the bottom of the spray tower body 1, playing a filtering role.

[0035] like Figure 3 As shown, the filter plate assembly includes a first filter plate 18 and a second filter plate 19, and a fastener 20 is connected between the first filter plate 18 and the second filter plate 19. The first filter plate 18 and the second filter plate 19 are fixed in the mounting groove 171 by the fastener 20, so that the two are fixed, and the distance between the two can be changed. At the same time, multiple filtering can be carried out, and the filtering effect is better.

[0036] An annular groove 41 is formed on the top of the mounting frame 4 . The annular groove 41 is located below the gear 7 . The rack 6 matched with the gear 7 is fixedly connected in the annular groove 41 .

[0037] Furthermore, a liquid level gauge 13 for detecting the internal liquid level height of the spray tower body 1 is installed on the surface of the spray tower body 1. The liquid level gauge 13 can detect the liquid level height of the water storage area for manual inspection, which is more conducive to observing the changes in the internal liquid level height during the subsequent replacement of the stored water.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
