Description

Technical Field

[0001] This utility model relates to the field of sulfur-containing wastewater treatment in oil and gas fields, specifically a desulfurization and deodorization device for sulfur-containing wastewater in oil and gas fields. Background Technology

[0002] Sulfur-containing wastewater from oil and gas fields is highly polluting wastewater generated during oil and gas extraction, gathering, transportation, and treatment. This wastewater also contains petroleum. If discharged directly without treatment, the sulfides in the wastewater will volatilize into the air, forming foul-smelling gases and affecting the surrounding air quality. Furthermore, with increasingly stringent environmental regulations, the discharge standards for sulfur-containing wastewater from oil and gas fields are becoming increasingly stringent. Therefore, desulfurization and deodorization treatment of sulfur-containing wastewater is a necessary measure. Adding sulfur-containing wastewater to a desulfurization and deodorization device can ensure it meets discharge standards, preventing environmental pollution and reducing adverse impacts on surrounding residents and ecosystems.

[0003] According to Chinese Patent No. CN209815859U, a device for deodorizing sulfur-containing wastewater in oil fields is disclosed. This utility model solves the problem that sulfur-containing wastewater has a strong odor and that the discharge of sulfur-containing wastewater into the outside world can easily affect the surrounding environment and the lives of residents.

[0004] Regarding the aforementioned patent content, the system includes an oil pump, an oil phase delivery pipe, and a crude oil treatment tank. A desulfurization layer is installed inside the crude oil treatment tank. The oil pump draws oil into the crude oil treatment tank for desulfurization. However, after the crude oil enters the crude oil treatment tank through the oil delivery pipe, it only passes through the desulfurization layer directly below the oil delivery pipe (i.e., the middle part of the desulfurization layer). It is difficult for the crude oil to be dispersed and flow to other parts of the desulfurization layer. As a result, only the middle part of the desulfurization layer continuously desulfurizes the crude oil, while other parts of the desulfurization layer cannot continuously desulfurize the crude oil due to the small amount of crude oil passing through them. This reduces the overall use and desulfurization effect of the desulfurization layer. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a desulfurization and deodorization device for sulfur-containing wastewater in oil and gas fields, so as to solve the technical problem that crude oil is difficult to disperse and flow onto the desulfurization layer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization and deodorization device for sulfur-containing wastewater from oil and gas fields, comprising a three-phase separator body, a crude oil treatment tank, and a wastewater treatment tank.

[0013] By adopting the above technical solution, the filter screen can filter impurities in wastewater, and the cooperation between the first sealing plate and the sealing gasket can improve the sealing between the filter screen and the wastewater treatment tank.

[0014] Furthermore, a guide plate is installed at the bottom of the interior of the wastewater treatment tank. The guide plate is located directly below the filter screen, and the top of the guide plate is smooth.

[0015] By adopting the above technical solution, the wastewater will flow downwards after being filtered by the filter screen and will flow to the guide plate, which can guide the wastewater.

[0027] 1. This utility model, by incorporating a movable component, allows for the dispersion of petroleum onto the desulfurization layer for desulfurization treatment. The operator can activate a first motor, which drives a turntable to rotate, which in turn drives a pull plate to rotate. The pull plate then moves a movable rod, which in turn moves the oil collection tank. As the turntable continues to rotate, the pull plate moves the movable rod back and forth, causing the oil collection tank to move back and forth as well. This allows the petroleum in the collection tank to be dispersed through the oil distribution holes and flow onto the desulfurization layer, preventing the petroleum from only flowing through the middle of the desulfurization layer. This ensures that other parts of the desulfurization layer can also desulfurize the petroleum, thereby improving the desulfurization effect of the desulfurization layer on the petroleum.

[0028] 2. This utility model is equipped with a guide rod and a guide seat. When the oil tank moves, the guide seat can move on the guide rod, and the guide rod can provide guidance, thereby improving the stability of the guide seat and the oil tank when they move. Attached Figure Description

[0045] Example 3: Based on Example 1 above, in order to adsorb and purify the gas entering the adsorption box 25, the following structure will be set up.

[0046] See Figure 1 , Figure 2 and Figure 7 An adsorption box 25 is installed at one end of the exhaust pipe 24. The top of the adsorption box 25 has multiple inlets 23.

[0047] The working principle of this utility model is as follows: First, when using the device, the power supply is turned on. Then, sulfur-containing wastewater is introduced into the three-phase separator body 1 through the inlet pipe 4. Subsequently, the screw pump 2, oil pump 6, and first blower 3 are started. Under the action of the screw pump 2, the wastewater flows from the three-phase separator body 1 into the wastewater treatment tank 19 through the water phase conveying pipe 18. Then, the wastewater flows onto the filter screen 10, and after being filtered by the filter screen 10, it continues to flow downward. Next, the valve on the feed pipe 8 is opened, and then the deodorizing agent can be added into the wastewater treatment tank 19 through the feed pipe 8. The second motor 14 is started, which drives the stirring shaft 16 to rotate, thereby driving the stirring blades 17 to rotate. The stirring blades 17 then fully stir the wastewater, causing the deodorizing agent to react with the wastewater, thus deodorizing the wastewater. When the wastewater needs to be discharged after deodorization, the drain valve on the drain pipe 15 can be opened, allowing the deodorized wastewater to be discharged through the drain pipe 15. The wastewater can then flow into the next treatment process for further processing (the next treatment process can be filtration of the deodorized wastewater, and how to filter it is not described in detail in this application).

[0048] Under the action of the first blower 3, the sulfur-containing gas in the three-phase separator body 1 can enter the external combustion furnace through the gas phase conveying pipe 29 for combustion treatment. The gas outlet pipe of the combustion furnace is equipped with a filter screen and an activated carbon adsorption layer to filter and purify the gas after combustion before it is discharged. Under the action of the oil pump 6, the oil in the three-phase separator body 1 can flow into the crude oil processing tank 7 through the oil phase conveying pipe 5. Then, the first motor 906 and the second blower 27 are started. The operation of the first motor 906 can drive the turntable 907 to rotate, which in turn drives the pull plate 908 to rotate. The pull plate 908 drives the movable rod 909 to move, and then... The oil collection tank 903 moves, and as the turntable 907 continues to rotate, the pull plate 908 drives the movable rod 909 to move back and forth, and drives the oil collection tank 903 to move back and forth, so that the oil in the oil collection tank 903 can be dispersed through the oil distribution hole 904 to the desulfurization layer 20. The desulfurization layer 20 desulfurizes the oil, and the desulfurized oil is discharged through the oil drain pipe 22. Under the action of the second fan 27, the outside air is filtered by the filter screen and enters the crude oil processing tank 7 through the second fan 27, so that the gas in the crude oil processing tank 7 can enter the adsorption tank 25 through the exhaust pipe 24, and is discharged after being adsorbed and purified by the activated carbon layer 26 in the adsorption tank 25.
