Description

Microwave cyclone separator Technical Field The utility model relates to a microwave cyclone separator. Background The oil is produced, transported and refined, the oil-containing waste water is inevitably produced in the production process of the petroleum-based derivative, and the cyclone separator is a pretreatment device for separating oil sludge from the oil-containing waste water at present. However, a large amount of oil substances, polymers and suspended matters exist in the oily wastewater, so that the oily wastewater has certain viscosity, has great influence on the removal of residual oil, suspended matters, solid particles and other impurities in the wastewater, causes incomplete solid-liquid separation, needs further treatment, and increases the treatment time and strength. Chinese patent CN112316500 discloses an ultrasonic cyclone separator, which uses ultrasonic vibration to strip the sediment from the oil-water in the sediment mixed solution, but the method can only realize solid-liquid two-phase separation, and the requirement can be met by further separating the oil from the water; chinese patent CN112047602 discloses an oily sludge cyclone sedimentation separation device, which implements three-phase separation of oily sludge water, but the method does not solve the problem of high viscosity of oily sludge. A microwave cyclone separator is therefore proposed for the above problems. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides the microwave cyclone separator which has the advantages of good three-phase separation effect, simple device and convenient operation. In order to achieve the purpose, the utility model provides the technical scheme that the microwave cyclone separator comprises a cyclone separator main body, wherein an upper oil-water separation cavity, a middle solid-liquid separation cavity and a lower solid discharge cavity are sequentially arranged in the cyclone separator main body from top to bottom; The top of the upper oil-water separation cavity is connected with an oil drain port, the side wall is connected with a water outlet; the side wall of the middle solid-liquid separation cavity is connected with a liquid inlet; The lower end of the lower solid discharge cavity is connected with a mud discharge port; the outer wall of the cyclone separator main body is connected with a separation driving assembly. Preferably, a spiral guide plate is arranged in the solid-liquid separation cavity in the middle of the cyclone separator main body. Preferably, the separation driving assembly comprises a microwave generating device, the microwave generating device is arranged on the outer wall of the cyclone separator main body, the inner wall of the middle solid-liquid separation cavity is provided with opposite microwave reflecting pipes, and the microwave generating device is connected with one of the microwave reflecting pipes through the microwave pipe. Preferably, the upper oil-water separation cavity is communicated with the middle solid-liquid separation cavity through an overflow port. Preferably, a filter screen is arranged in the overflow port. Preferably, the lower solids discharge chamber is tapered. Compared with the prior art, the microwave cyclone separator has the beneficial effects that by arranging the microwave generating device, the thermal effect and the non-thermal effect of microwave radiation reduce the viscosity of oily wastewater, solve the problem that oil-water and sediment cannot be completely separated due to high viscosity of the oily wastewater, promote the separation of the oil-water and the sediment, and ensure that the sediment separation rate is more than 98%. The oil-water separation cavity arranged in the device enables oil and water to be separated, the separated oil and water are recycled or treated respectively, subsequent oil-water separation treatment is avoided, treatment time and strength are reduced, and the three-phase separation effect of oil and water is achieved. Solves the problem that the oily wastewater has high viscosity and can not be thoroughly subjected to solid-liquid separation, has good three-phase separation effect, avoids subsequent oil-water separation treatment, and has simple device and convenient operation.
