Description

Technical Field

[0001] This utility model relates to the field of emulsified sludge treatment technology, specifically to a device for ultrasonic demulsification of emulsified sludge. Background Technology

[0002] Emulsified sludge oil originates primarily from the separation oil from electrostatic desalination wastewater, the flotation oil from wastewater purification, and the stripping oil from some production and maintenance processes in petroleum refining. This sludge oil is characterized by high water content, high salt content, high ash (scum, mud) content, and a stable emulsion system composed of a large amount of residual oil recovery and refining additives. It cannot be directly processed in secondary processing units. Currently, vacuum distillation is used for deep dehydration of the sludge oil, but inorganic salts, scum, ash, and residual surfactants are not effectively removed. This results in the sludge being recycled into the coking unit, leading to increased chloride content in the feedstock, higher pressure at the top of the fractionation tower, and deterioration in product quality, threatening the safe and stable operation of the coking unit. The key to oil-water separation of emulsified sludge oil is demulsification, which can be achieved through chemical, biological, and physical methods. Physical demulsification mainly uses ultrasonic methods. While ultrasonic methods have the advantage of no secondary pollution, they are technically challenging, and current applications commonly suffer from insufficient demulsification or secondary emulsification.

[0003] Existing technology publication CN210825911U discloses an ultrasonic demulsification device for oily sludge. This utility model belongs to the field of oily sludge treatment technology and relates to an ultrasonic demulsification device for oily sludge, including a device body and an ultrasonic transducer; the ultrasonic transducer includes several transducers and at least one transducer with a special-shaped tool head; the device body includes a thin-walled cylindrical body and end caps at both ends of the body; the several transducers are uniformly and vertically installed on the outer wall of the body; the transducer with the special-shaped tool head is installed along the axis of the device body in the middle of the end cap of the device body, and the axis of the transducer with the special-shaped tool head coincides with the axis of the device body. This utility model is a simple and reasonable ultrasonic demulsification device for oily sludge, with no dead angles and high demulsification efficiency.

[0004] An existing ultrasonic demulsification device for oily sludge has poor demulsification efficiency and effect in practical use, resulting in low practicality. Utility Model Content

[0005] The purpose of this invention is to provide a device for ultrasonic demulsification of emulsified sludge oil, so as to solve the problems of poor demulsification efficiency and effect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for ultrasonic demulsification of emulsified sludge, comprising a protective shell, a fixed support plate fixedly installed inside the protective shell, an ultrasonic demulsification tank fixedly installed at the upper end of the fixed support plate, an aluminum silicate insulation layer fixedly provided on the inner wall of the ultrasonic demulsification tank, a stirring motor fixedly installed at the upper end of the protective shell, a rotating shaft fixedly installed at the transmission end of the lower end of the stirring motor, a movable ring fixedly installed inside the ultrasonic demulsification tank, and stirring rods fixedly installed at the left and right ends of the rotating shaft.

One end of the ultrasonic transducer is connected to the ultrasonic demulsifying tank, and the other end is fixedly installed with an ultrasonic generator. A rubber sealing ring is provided at the connection between the ultrasonic transducer and the ultrasonic demulsifying tank. The ultrasonic transducer is electrically connected to the ultrasonic generator.

[0008] Preferably, a sludge inlet pipe is fixedly installed at the upper end of the protective shell, and a cleaning agent inlet pipe is fixedly installed at the upper end of the protective shell.

[0010] Preferably, a fixed support column is fixedly installed at the lower end of the protective shell, and a rubber anti-slip ring pad is fixedly installed at the lower end of the fixed support column.

[0011] Preferably, an electric push rod is fixedly installed inside the fixed support column, and a swivel wheel is fixedly installed at the transmission end of the lower end of the electric push rod.

[0012] Preferably, a control panel is fixedly installed at the front end of the protective shell, and the control panel is electrically connected to the stirring motor, the ultrasonic transducer, the pump and the electric push rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This ultrasonic demulsification device for emulsified sludge oil pours sludge oil into the ultrasonic demulsification tank through the sludge oil inlet pipe and cleaning agent into the ultrasonic demulsification tank through the cleaning agent inlet pipe. The ultrasonic generator and ultrasonic transducer are activated to demulsify the sludge oil. At the same time, the stirring motor drives the rotating shaft and stirring rod to rotate, so that the sludge oil and cleaning agent are fully mixed in the ultrasonic demulsification tank. This helps to ensure that the emulsified components in the sludge oil can be evenly contacted by the ultrasonic waves and cleaning agent, improving the efficiency and effect of demulsification. If there is no stirring, the sludge oil and cleaning agent may separate into layers or have uneven concentrations in some areas, which will affect the demulsification process.

[0015] 2. The device for ultrasonic demulsification of emulsified sludge has a rubber anti-slip ring pad fixedly installed at the lower end of the fixed support column, which makes the device more stable and has better anti-slip properties. The electric push rod pushes the omnidirectional wheels downward, which allows people to move the device more quickly. Attached Figure Description

When the device for ultrasonic demulsification of emulsified sludge is needed, sludge is poured into the ultrasonic demulsification tank 3 through the sludge inlet pipe 11, and cleaning agent is poured into the ultrasonic demulsification tank 3 through the cleaning agent inlet pipe 12. The ultrasonic generator 10 and ultrasonic transducer 9 are started to demulsify the sludge. At the same time, the stirring motor 5 drives the rotating shaft 6 and stirring rod 8 to rotate, so that the sludge and cleaning agent are fully mixed in the ultrasonic demulsification tank 3. This helps to ensure that the emulsified components in the sludge can be evenly contacted by the ultrasonic waves and cleaning agent, improving the efficiency and effect of demulsification. If the sludge and cleaning agent are not stirred, the sludge and cleaning agent may separate into layers or have uneven concentrations in some areas, which will affect the demulsification process.

By pushing the movable universal wheel 19 downward by the electric push rod 18, people can move the device more quickly.

[0025] Working principle: When using this ultrasonic demulsifier for emulsified sludge, sludge is poured into the ultrasonic demulsifier tank 3 through the sludge inlet pipe 11, and cleaning agent is poured into the ultrasonic demulsifier tank 3 through the cleaning agent inlet pipe 12. The ultrasonic generator 10 and ultrasonic transducer 9 are activated to demulsify the sludge. At the same time, the stirring motor 5 drives the rotating shaft 6 and stirring rod 8 to rotate, so that the sludge and cleaning agent are fully mixed in the ultrasonic demulsifier tank 3. This helps to ensure that the emulsified components in the sludge can be evenly contacted by the ultrasonic waves and cleaning agent, improving the efficiency and effect of demulsification. If there is no stirring, the sludge and cleaning agent may separate or have uneven concentrations in some areas, which will affect the demulsification process. The rubber anti-slip ring pad 17 is fixedly installed at the lower end of the fixed support column 16, which makes the device more stable and has better anti-slip properties. The electric push rod 18 pushes the caster wheel 19 downward, which allows people to move the device more quickly.
