Description

Technical Field

[0001] This utility model relates to a microwave cyclone separator. Background Technology

[0002] Oily wastewater is inevitably generated during the extraction, transportation, and refining of petroleum, as well as the production of petroleum-based derivatives. Hydrocyclones are currently the pretreatment devices for separating oily sludge from oily wastewater. However, oily wastewater contains a large amount of oil, polymers, and suspended solids, resulting in a certain viscosity. This viscosity significantly affects the removal of residual oil, suspended solids, and solid particles, leading to incomplete solid-liquid separation and requiring further treatment, thus increasing processing time and intensity.

[0003] Chinese patent CN112316500 discloses an ultrasonic cyclone separator that uses ultrasonic vibration to separate the mud and sand from the oil and water in a mud-sand mixture. However, this method can only achieve solid-liquid two-phase separation, and further oil-water separation is required to meet the requirements.

[0004] Chinese patent CN112047602 discloses a cyclone sedimentation separation device for oily sludge. This invention achieves three-phase separation of oil, sludge and water, but the method does not solve the problem of high viscosity of oily sludge.

[0005] Therefore, a microwave cyclone separator is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the existing defects and provide a microwave cyclone separator with good three-phase separation effect, simple device and convenient operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a microwave cyclone separator, comprising a cyclone separator body, wherein an upper oil-water separation chamber, a middle solid-liquid separation chamber, and a lower solid discharge chamber are arranged sequentially from top to bottom inside the cyclone separator body;

[0008] The top of the upper oil-water separation chamber is connected to an oil drain port, and the side wall is connected to a drain port.

[0009] The side wall of the central solid-liquid separation chamber is connected to a liquid inlet;

[0010] The lower end of the lower solid discharge chamber is connected to the mud discharge port;

[0011] The outer wall of the cyclone separator body is connected to the separation drive assembly.

[0012] Preferably, a spiral guide plate is provided in the solid-liquid separation chamber in the middle of the main body of the cyclone separator.

[0013] Preferably, the separation drive assembly includes a microwave generator, which is disposed on the outer wall of the cyclone separator body, and opposite microwave reflectors are disposed on the inner wall of the central solid-liquid separation chamber. The microwave generator is connected to one of the microwave reflectors through a microwave tube.

[0014] Preferably, the upper oil-water separation chamber and the middle solid-liquid separation chamber are connected through an overflow port.

[0015] Preferably, a filter screen is provided inside the overflow port.

[0016] Preferably, the lower solid discharge cavity is conical.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: This microwave cyclone separator, by incorporating a microwave generator, reduces the viscosity of oily wastewater through the thermal and non-thermal effects of microwave radiation. This solves the problem of incomplete separation of oil and water from sediment caused by the high viscosity of oily wastewater, promoting the separation of oil and water from sediment, with a sediment separation rate exceeding 98%. The oil-water separation chamber in the device separates the oil and water, allowing for recycling or treatment of the separated oil and water, avoiding subsequent oil-water separation treatment, reducing processing time and intensity, and achieving a three-phase separation effect of oil, sludge, and water. It solves the problem of incomplete solid-liquid separation due to the high viscosity of oily wastewater, provides excellent three-phase separation, avoids subsequent oil-water separation treatment, and is simple and easy to operate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 A microwave cyclone separator includes a cyclone separator body 2. Inside the cyclone separator body 2, from top to bottom, are arranged an upper oil-water separation chamber 10, a middle solid-liquid separation chamber 11, and a lower solid discharge chamber 12. The upper oil-water separation chamber 10 has an oil drain port 7 connected to its top and a drain port 6 connected to its side wall. The middle solid-liquid separation chamber 11 has a liquid inlet 1 connected to its side wall. A spiral guide plate 4 is installed inside the middle solid-liquid separation chamber 11. The lower end of the lower solid discharge chamber 12 is connected to a sludge discharge port 5; the lower solid discharge chamber 12 is conical.

[0023] Specifically, a separation drive assembly is connected to the outer wall of the cyclone separator body 2. The separation drive assembly includes a microwave generator 8, which is disposed on the outer wall of the cyclone separator body 2. Opposite microwave reflectors 9 are disposed on the inner wall of the central solid-liquid separation chamber 11. The microwave generator 8 is connected to one of the microwave reflectors 9 via the microwave tubes. The microwave generator 8 generates high-frequency electromagnetic waves, which are then transmitted to the cyclone separator chamber through the microwave tubes. The microwave reflector 9 is connected to one end of the microwave tubes to enhance the microwave effect.

[0024] Specifically, the upper oil-water separation chamber 10 and the middle solid-liquid separation chamber 11 are connected by an overflow port 3. A filter screen is installed inside the overflow port 3 to trap fine particles in the oil and water, thereby improving the purity of the overflow oil and water.

[0025] Specifically, during use, oily wastewater enters the main body 2 of the hydrocyclone separator through the inlet 1. The microwave generator 8 is turned on, and the oil-sludge-water mixture first flows downward along the spiral guide plate 4. Under the action of centrifugal force and gravity, solid-liquid separation is achieved at the solid discharge chamber 12 at the bottom of the cone. The mud and sand particles fall into the slag hopper of the cone and are discharged through the sludge discharge port 5. The oil and water flow upward along the axis and enter the upper oil-water separation chamber 10 through the overflow port 3. According to the density difference between oil and water, they are separated by sedimentation. The oil is discharged through the top oil discharge port 7, and the water is discharged through the drain port 6. The separated oil and water are recycled or further processed to achieve three-phase separation of oil, sludge, and water. The microwave radiation generated by microwave generator 8 has two effects: thermal and non-thermal. The high temperature generated by the thermal effect keeps the oily wastewater in a fluid state, preventing the oil-sludge-water mixture from solidifying. The external electromagnetic field generated by the non-thermal effect causes water molecules to dipoleize and rotate at high speed, reducing the viscosity of the oily wastewater, improving the oil-sludge-water separation effect, and promoting the separation between oil-water and silt particles, thus achieving efficient three-phase separation of oil, sludge, and water. Microwave generator 8 is an existing device, and its model can be... SMF100A.

[0026] This microwave cyclone separator, through the inclusion of a microwave generator 8, utilizes the thermal and non-thermal effects of microwave radiation to reduce the viscosity of oily wastewater. This solves the problem of incomplete separation of oil and water from sediment caused by the high viscosity of oily wastewater, promoting the separation of oil and water with sediment, achieving a sediment separation rate of over 98%. The oil-water separation chamber within the device ensures effective separation of oil and water. The separated oil and water are then recycled or treated separately, avoiding subsequent oil-water separation treatment, reducing processing time and intensity, and achieving a three-phase separation effect of oil, sludge, and water. It solves the problem of incomplete solid-liquid separation due to the high viscosity of oily wastewater, providing excellent three-phase separation, avoiding subsequent oil-water separation treatment, and is simple and easy to operate.
