Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to a waste gas treatment spray device for oil drilling and production environments. Background Technology

[0002] Waste gas scrubbing devices are widely used in the treatment of waste gases in petroleum production, especially for harmful gases generated during oil and gas separation, storage, and transportation. Their main function is to adsorb and scrub the waste gas with sprayed liquid, thereby removing harmful components such as hydrogen sulfide, nitrogen oxides, and volatile organic compounds. The device consists of a spray tower, a spraying device, a circulating water tank, and a gas emission system. The waste gas first enters the spray tower, where the spraying device atomizes water or a chemical solution and brings it into full contact with the waste gas, absorbing the pollutants. The scrubbed gas is then discharged through the top of the tower, meeting emission standards. The waste liquid is treated and reused through a recycling system, reducing resource waste.

[0027] Example

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a waste gas treatment spray device for oil drilling and production environment, including a waste gas treatment tower 1, which is the core body of the entire waste gas treatment device, providing space for the purification and treatment of waste gas. A second circulation pipe 4 is fixedly connected to one side of the waste gas treatment tower 1, which plays the role of transporting treatment liquid, so that the treatment liquid can circulate in the waste gas treatment tower 1. A protective cover 5 is fixedly installed on the outer periphery of one end of the second circulation pipe 4, which protects the internal rotating component, prevents the waste gas from damaging the rotating component, and also reduces the noise leakage generated by the rotating component during operation. The rotating component is installed inside the protective cover 5.

[0029] A fan 12 is fixedly installed at one end of the exhaust gas treatment tower 1 to provide power to the swirl guide plate 16, so that the exhaust gas can increase the contact area with the spray water inside the device. A quick-release assembly is provided at the end of the fan 12 near the exhaust gas treatment tower 1, and the swirl guide plate 16 is provided at the end of the quick-release assembly away from the fan 12.

[0030] The rotating assembly includes a rotating shaft 7, a worm gear 8, and a worm wheel 9. A motor 6 is fixedly installed inside the protective cover 5. The output end of the motor 6 is coaxially fixedly connected to the rotating shaft 7. The rotating shaft 7 transmits the rotational power of the motor 6 to the worm gear 8, causing it to rotate synchronously. The worm gear 8 is coaxially fixedly connected to the outer periphery of the rotating shaft 7. The bottom of the second circulation pipe 4 is rotatably connected to the spray box 10 through a sealed bearing. The top outer periphery of the spray box 10 is coaxially fixedly connected to the worm wheel 9. When the worm wheel 9 rotates, it drives the spray box 10 to rotate around the sealed bearing. The teeth of the worm gear 8 and the worm wheel 9 mesh. Multiple nozzles 11 are fixedly installed at the bottom of the spray box 10. When the spray box 10 rotates, it drives the nozzles 11 to make circular motion, so that when the treatment liquid is sprayed from the nozzles 11, it forms a rotating liquid curtain, which expands the contact area between the treatment liquid and the exhaust gas and improves the exhaust gas treatment effect.

[0031] The quick-release assembly includes a connecting seat 13, a connector 14, and a sliding ring 15. The connecting seat 13 is fixedly installed on one side of the exhaust gas treatment tower 1, providing a foundation support for the installation of the swirl guide plate 16. Connecting grooves are provided on both sides of the connecting seat 13, and the connector 14 is slidably connected inside the connecting grooves. The connector 14 can slide within the connecting grooves, facilitating the installation and removal of the swirl guide plate 16. The end of the connector 14 away from the connecting seat 13 is fixedly connected to one end of the swirl guide plate 16. The sliding ring 15 is slidably connected to the outer periphery of the connecting seat 13, and a fastening groove is provided inside the sliding ring 15. The fastening groove cooperates with both ends of the connector 14. When the swirl guide plate 16 needs to be installed, the connector 14 is slid into the connecting groove, and then the sliding ring 15 is slid to make the fastening groove lock the two ends of the connector 14, realizing the quick installation of the swirl guide plate 16. When it needs to be removed, the sliding ring 15 is slid in the opposite direction to remove the connector 14 from the connecting groove, realizing quick removal.

[0032] A support frame 2 is fixedly installed on the outer periphery of the exhaust gas treatment tower 1. A water pump 20 is fixedly installed on the top of the support frame 2. The input end of the water pump 20 is fixedly connected to a first circulation pipe 3. The end of the first circulation pipe 3 away from the water pump 20 is fixedly connected to the bottom of the exhaust gas treatment tower 1. The output end of the water pump 20 is fixedly connected to one end of a second circulation pipe 4. After the water pump 20 is started, it draws the treatment liquid from the bottom of the exhaust gas treatment tower 1 through the first circulation pipe 3, and then transports the treatment liquid to the spray box 10 through the second circulation pipe 4, thereby realizing the circulation of the treatment liquid. This system utilizes water resources and ensures sufficient treatment liquid in the waste gas treatment tower 1 for waste gas treatment. A guide ring 17 is fixedly installed inside the waste gas treatment tower 1, and a spring 18 is fixedly installed at the bottom of the guide ring 17. A filter screen 19 is fixedly connected to the end of the spring 18 away from the guide ring 17, which can filter impurities in the treatment liquid and prevent impurities from clogging the nozzle 11 and affecting the waste gas treatment effect. An outlet pipe 22 is fixedly connected to one side of the waste gas treatment tower 1, and an inlet pipe 21 is fixedly connected to the top of the waste gas treatment tower 1.

[0033] The working process of this utility model:

[0034] Step 1: First, pour spray water into the device, then connect the exhaust gas to the inlet pipe 21, and start the water pump 20 to draw the treatment liquid from the bottom of the tower. The liquid is then transported to the spray box 10 through the second circulation pipe 4. The motor 6 drives the rotating shaft 7 and the worm gear 8 to rotate. The worm gear 8 drives the worm wheel 9 and the spray box 10 to rotate. The nozzle 11 sprays out rotating liquid mist. The exhaust gas comes into initial contact with the liquid mist, and some pollutants are adsorbed and dissolved. The swirl guide plate 16 guides the airflow to form a swirl, increasing the residence time of the exhaust gas.

[0035] Step 2: The exhaust gas continues to rise or fall in the tower, making full contact with the treatment liquid to further remove pollutants. The treatment liquid falls back to the bottom of the tower and is filtered by the filter screen 19. Impurities are trapped and the treatment liquid can be recycled. The spring 18 buffers the force on the filter screen 19 to prevent it from being deformed or damaged by water flow impact and exhaust gas corrosion, thus ensuring the filtration effect.

[0036] Step 3: The purified exhaust gas is discharged from the exhaust pipe 22. When the swirl guide plate 16 malfunctions, it can be quickly disassembled and replaced using the quick-release assembly to ensure the normal operation of the device.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
