Description

Technical Field

[0001] This utility model relates to the field of crude oil sludge treatment technology, specifically to an oil-water separator for crude oil sludge reduction treatment. Background Technology

[0002] Crude oil sludge treatment refers to the process of treating oily solid waste, namely crude oil sludge, generated during oil extraction, transportation, refining, and storage. Crude oil sludge is a complex mixture, mainly composed of petroleum hydrocarbons, water, solid particles, and other impurities. Due to its high petroleum hydrocarbon content, crude oil sludge possesses both polluting and resource recovery value, thus requiring effective treatment.

[0003] Currently, crude oil sludge contains a large amount of petroleum hydrocarbons, water, and solid particles. Due to their small density differences, they are difficult to separate naturally. Petroleum hydrocarbons and water mix together to form emulsions, resulting in poor separation. The separated oil may contain a large amount of water, and the aqueous phase may also contain a significant amount of oil, reducing the oil recovery rate and water quality compliance. The solid particles in the sludge are of varying sizes. If they are not stirred, the heavier particles will quickly settle to the bottom, forming a thick sediment layer, while the lighter particles may remain suspended on the surface, resulting in uneven distribution of solid particles. This not only affects subsequent solid particle treatment but also necessitates the use of oil-water separators for crude oil sludge reduction treatment to address these issues. Utility Model Content

[0004] To address the problems currently encountered in crude oil sludge, which contains large amounts of petroleum hydrocarbons, water, and solid particles, and whose small density differences make natural separation difficult, petroleum hydrocarbons and water tend to mix and form emulsions, resulting in poor separation. The separated oil may contain a large amount of water, and the aqueous phase may also contain a significant amount of oil, reducing oil recovery rates and water quality compliance. Furthermore, the solid particles in the sludge vary in size; without stirring, heavier particles quickly settle to the bottom, forming a thick sediment layer, while lighter particles may remain suspended on the surface, leading to uneven distribution of solid particles. This not only affects subsequent solid particle processing but also addresses the issues raised in the background art by providing an oil-water separator for reducing the volume of crude oil sludge.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An oil-water separator for reducing crude oil sludge volume includes a main body, and a processing component is fixedly connected to the top of the main body;

[0007] The processing assembly includes a tank, the inner part of which is divided into a feeding zone, a separation zone and a discharging zone. A variable frequency motor is installed on the top of the tank, and a stirring rod is fixedly connected to the output end of the variable frequency motor. A stirring blade is fixedly connected to the bottom of the stirring rod. A temperature sensor and an electric heating wire are fixedly connected inside the tank, and a controller is fixedly connected to the side of the tank.

[0008] As a preferred embodiment of this utility model, a pressure sensor and a liquid level sensor are fixedly connected inside the tank, and several electric heating wires are provided and evenly distributed.

[0009] As a preferred embodiment of this utility model, a control screen is fixedly connected to the side of the controller, and two adjustment buttons are provided on the side of the controller.

[0010] As a preferred embodiment of this utility model, a slag discharge pipe is provided at the bottom of the tank, and a drain pipe is fixedly connected to the bottom of the tank.

[0011] As a preferred embodiment of this utility model, a reinforcing steel ring is fixedly connected to the side of the tank, a feed inlet is fixedly connected to the top of the tank, and a protrusion is fixedly connected to the side of the tank.

[0012] As a preferred embodiment of this utility model, the main body includes a support frame, and a support rod is fixedly connected to the bottom of the support frame.

[0013] As a preferred embodiment of this utility model, a pad is fixedly connected to the bottom of the support rod, and four support rods and pads are provided.

[0014] As a preferred embodiment of this utility model, the support frame is internally fixedly connected with reinforcing ribs, and the top of the support frame is fixedly connected with a connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the heating temperature of the electric heating wire is monitored and controlled by a temperature sensor. Heating can significantly reduce the viscosity of the oil, making it easier to separate from water. Heating can increase the density difference between oil and water, further promoting separation. At the same time, heating can promote the separation and discharge of corrosive components, reducing their contact time with the equipment, thereby reducing the risk of equipment corrosion. Heating can ensure the stability of the separation process and reduce the fluctuation of separation effect caused by the difference in the composition of crude oil sludge.

[0017] 2. In this utility model, by using a variable frequency motor to drive the stirring blades on the stirring rod to stir the crude oil sludge, the solid particles in the crude oil sludge can be kept in a suspended state, preventing them from quickly settling to the bottom and forming a thick sediment layer. This can avoid equipment blockage, and at the same time, the solid particles are evenly distributed during the separation process. The shortened processing time means that the equipment can process new crude oil sludge faster, thereby improving the utilization rate of the equipment. Furthermore, the use of a variable frequency motor drive allows the stirring speed to be adjusted according to the characteristics of the crude oil sludge. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0025] An oil-water separator for crude oil sludge reduction treatment includes a main body 1, with a processing component 2 fixedly connected to the top of the main body 1.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the processing component 2 includes a tank 201, which is divided into a feeding zone, a separation zone, and a discharge zone. A variable frequency motor 204 is installed on the top of the tank 201, and a stirring rod 205 is fixedly connected to the output end of the variable frequency motor 204. A stirring blade 206 is fixedly connected to the bottom of the stirring rod 205. A temperature sensor 208 and an electric heating wire 211 are fixedly connected inside the tank 201. A controller 214 is fixedly connected to the side of the tank 201. The temperature sensor 208 monitors and controls the heating temperature of the electric heating wire 211. Heating can significantly reduce the viscosity of the oil, making it easier to separate from water. Heating can increase the density difference between oil and water, further promoting separation. At the same time, heating can promote the separation and discharge of corrosive components, reducing their contact time with the equipment, thereby reducing the risk of equipment corrosion. Heating can ensure the stability of the separation process and reduce the fluctuation of the separation effect caused by the difference in the composition of the crude oil sludge.

[0027] The tank 201 is internally equipped with a pressure sensor 209 and a level sensor 210. Several electric heating wires 211 are evenly distributed. A control panel 215 is fixedly connected to the side of the controller 214, which has two adjustment buttons 216. A slag discharge pipe 212 and a drain pipe 213 are fixedly connected to the bottom of the tank 201. A reinforcing steel ring 202 is fixedly connected to the side of the tank 201, and a feed inlet 207 is fixedly connected to the top of the tank 201. The side of the tank 201 is fixedly connected to a protrusion 203. The stirring blades 206 on the stirring rod 205 are driven by the variable frequency motor 204 to stir the crude oil sludge. This keeps the solid particles in the crude oil sludge in a suspended state, preventing them from quickly settling to the bottom and forming a thick sediment layer. This avoids equipment blockage and ensures that the solid particles are evenly distributed during the separation process. The shortened processing time means that the equipment can process new crude oil sludge faster, thereby improving the utilization rate of the equipment. Furthermore, the variable frequency motor 204 can be used to drive the stirring speed according to the characteristics of the crude oil sludge.

[0028] In this embodiment, as Figure 1 and Figure 4 As shown, the main body 1 includes a support frame 101. A support rod 102 is fixedly connected to the bottom of the support frame 101. A pad 103 is fixedly connected to the bottom of the support rod 102. Four support rods 102 and pads 103 are provided. A reinforcing rib 105 is fixedly connected inside the support frame 101. A connecting plate 104 is fixedly connected to the top of the support frame 101. The reinforcing rib 105 can effectively disperse the pressure on the tank 201, avoid excessive local stress leading to deformation or damage, and thus significantly improve the pressure resistance of the tank 201.

[0029] The working process of this utility model is as follows: When the oil-water separation tank for crude oil sludge reduction treatment designed in this scheme is working, the tank body 201 is divided into multiple areas, including a feeding area, a separation area, and a discharging area. A heating mechanism is used to heat the crude oil sludge. A stirring mechanism is installed in the feeding area and the separation area to stir the crude oil sludge. An oil-water separation device is installed in the separation area, including multiple inclined plates and an oil collection tank. A drain pipe 213 extends to the bottom of the separation area to discharge the separated water. A slag discharge pipe 212 is installed at the slag outlet to discharge the separated solid particles. A temperature sensor 208 monitors and controls the heating temperature of the electric heating wire 211. Heating can significantly reduce the viscosity of the oil, making it easier to separate from water. A variable frequency motor 204 drives the stirring blades 206 on the stirring rod 205 to stir the crude oil sludge. The stirring mechanism is driven by a variable frequency motor 204, and the stirring speed can be adjusted according to the characteristics of the crude oil sludge. This equipment has a simple structure, is easy to operate, and has low cost. It can efficiently separate oil, water, and solid particles in crude oil sludge, realizing resource recovery and environmental protection.
