Description

High-efficiency cyclone Technical Field The utility model relates to the technical field of oil-water cyclone separators, in particular to a high-efficiency cyclone. Background The oil-water cyclone separator realizes oil-water two-phase separation based on the difference of centrifugal force and density. The mixed liquid enters the cyclone cavity through the tangential inlet to form a high-speed rotating flow field (the centrifugal acceleration can reach more than 2000 g), the water phase with high density is thrown to the outer wall and is discharged along the bottom flow port, and the light oil is gathered towards the center and is led out through the overflow port, so that the high-efficiency separation is realized. In the prior art, only one oil-water mixed liquid inlet is generally arranged in the oil-water cyclone separator, and the tangential liquid inlet of the single inlet is easy to cause uneven distribution of fluid in the cyclone cavity, so that a local high turbulence area is easy to form, and a stable centrifugal separation flow field is damaged, thereby reducing the coalescence efficiency of oil drops. Disclosure of utility model The utility model aims to solve the problems in the background art, and further provides a high-efficiency cyclone. The technical scheme adopted for solving the technical problems is as follows: an efficient cyclone comprises a cyclone tube, an inlet channel, an overflow tube, a reducer tube and a water outlet tube, The four inlet channels with rectangular main body shapes are respectively communicated with the inside of the cyclone tube and are tangentially arranged with the cyclone tube to form a uniform rotary flow field; the overflow pipe is fixedly arranged at the top of the cyclone pipe and is communicated with the interior of the cyclone pipe; The cyclone tube, the reducer tube and the water outlet tube are connected coaxially from top to bottom in sequence, and the diameters of the cyclone tube, the reducer tube and the water outlet tube are reduced in sequence. Further, one end of the inlet channel far away from the swirl tube is blocked, a liquid inlet pipe communicated with the inside of the inlet channel is laterally and fixedly arranged, and the inlet channel is internally and rotatably connected with a rotating shaft, and a plurality of spiral guide vanes are arranged on the rotating shaft. Further, the arrangement angle of the spiral guide vanes is 18-23 degrees, and 6-8 spiral guide vanes are equidistantly arranged. According to the scheme, the rotating shaft and the spiral guide vanes are arranged in each inlet channel, so that the resistance of the spiral guide vanes can be overcome after the oil-water mixed liquid is pressurized and introduced into the inlet channels, the rotating shaft moves under the impact of fluid, the rotating energy can be enhanced, and then the oil-water mixed liquid is smoothly conveyed into the spiral pipes under the action of the spiral guide vanes, so that turbulence interference is further reduced. Further, the liquid inlet pipe is a rectangular pipe, and a filtering piece attached to the inner wall of the liquid inlet pipe is arranged at one end, far away from the inlet channel, of the liquid inlet pipe. According to the scheme, the oil-water mixed solution is filtered before being introduced, and the preposed filter element is added, so that the probability of equipment blockage caused by subsequent winding of fiber impurities on an overflow pipe or a spiral guide vane is avoided. Further, a flow regulating valve is arranged on the liquid inlet pipe. According to the scheme, the flow rate of the oil-water mixed liquid can be matched with the flow guiding capacity of the spiral guide vane through the flow regulating valve, and meanwhile, the fluid is ensured to have enough kinetic energy to overcome the resistance of the spiral guide vane so as to form stable rotational flow. Further, a heat tracing coil is arranged on the outer wall of the cyclone tube, and steam flows into the heat tracing coil. According to the scheme, the heat tracing coil pipe is arranged on the outer wall of the cyclone tube, and steam is introduced into the pipeline of the heat tracing coil pipe, so that the temperature of a key area can be maintained in a targeted manner (such as the prevention of condensation of high-viscosity crude oil), and the energy waste is reduced. Further, the reducing pipe and the water outlet pipe are provided with a heat tracing coil pipe, and steam flows into the heat tracing coil pipe. According to the scheme, the outer wall fully-wrapping type arrangement can ensure synchronous heating of the cyclone cavity, the reducing cavity and the water outlet cavity area, so that the situation that oil phase wax or water phase is frozen due to local low temperature is avoided, and the separation stability is improved by more than 30%. Further, the taper angle of the reducer pipe is 10-20 degrees. Further, the rotating shaft
