The traditional cyclone separator is usually provided with a rectangular or volute tangential inlet, the inherent air inlet mode of the traditional cyclone separator causes relatively large pressure loss, the traditional cyclone separator is not favorable for working conditions that the pressure is high and the pressure is in an attenuation trend, and the problems of low separation efficiency, blockage of a cyclone pipe, scaling and the like exist at present. Therefore, the novel guide vane type cyclone separator gradually appears in the field of view of the public, the air inlet mode of the novel guide vane type cyclone separator is different from that of a cut-in type cyclone separator, the novel guide vane type cyclone separator can bear higher pressure, and excessive loss caused by pressure difference can be improved.

The guide vane type cyclone separator has the following air inlet modes: the dusty airflow uniformly enters the cylinder of the separator along the axial direction, is guided by the guide vane serving as a cyclone after contacting the guide vane, is forced to change the flow direction to generate strong rotation, and forms a spiral shape to enter a separation space downwards along the cylinder; because the density of the gas phase and the solid phase has the difference of magnitude order, compared with the air flow, the solid particles are easier to move towards the cylinder wall under the driving of centrifugal force, and are brought to the dust removal port by the downward air flow and gravity after reaching the cylinder wall; the rotating airflow separated from the impurities can flow to the geometric center along the radial direction in the cone section, and finally the direction is converted to form an upward secondary vortex (inner vortex) which is discharged through the exhaust pipe.

The utility model discloses filter element 5 comprises filter body 12 and convex part 13, and filter body 12 is the wide-mouth cone structure or called tubulose trapezoidal platform structure down, and its wall inclination, promptly with the contained angle of 4 axial leads of blast pipe be 15, a plurality of through-holes of arranging on the lateral wall, through-hole inclination 25 ~ 30, link up blast pipe 4, supply pure interior whirl inflow blast pipe 4.

The diversion cone 6 is a solid inverted cone with the apex angle of 30 degrees, guides downward dusty airflow to enter a secondary separation unit or discharge, inhibits the airflow stagnation phenomenon caused by the inlet vortex of the lower cone 2, and the bottom surface of the diversion cone 6 is similar to a plane vortex limiter, so that the tail swing phenomenon at the tail end of the vortex in the filtering component 5 can be improved. The total height of the filter element 5 and the guide cone 6 is not greater than the height of the lower cone 2.

The top of the cylindrical shell 7 in the secondary separation unit B is sealed, the depth of the secondary exhaust pipe 10 is less than two thirds of the height of the cylindrical shell 7, and the arrangement is to prevent the remaining particle-containing airflow from tangentially entering the secondary separation unit B and not completely forming downward progressive spiral airflow to flow out along the secondary exhaust pipe 10. The diameter of the cylindrical shell 7 is 4.5 times of the diameter of the secondary exhaust pipe 10.

The connecting elbow C is vertically arranged in the embodiment, the inlet end of the connecting elbow C is connected with the cone outlet 103, the outlet end of the connecting elbow C is communicated with an equal-diameter opening arranged on one side of the top cavity wall of the cylindrical shell 7, and the angle of the connecting elbow is favorable for dust-containing airflow to tangentially enter the secondary separation unit.

As shown in FIG. 1, the guide vane type high-pressure cyclone separator with the guide flow filtering function comprises a separation unit A, a secondary separation unit B and a connecting elbow C.

As shown in fig. 2, the upper cylindrical barrel 1 and the lower cone 2 form an integral annular space of the separation unit a, and the top of the guide vane 3 is spaced from the axial inlet 101, so that the dusty airflow with initial velocity uniformly enters the annular space along the axial inlet 101. As can be seen from fig. 4, the inner edges 34 of the guide vanes are on the same cylindrical surface and fixedly connected with the outer wall of the exhaust pipe 4, the outer edges 35 of the vanes are bonded with the inner wall of the upper cylindrical barrel 1, and the six guide vanes 3 form a spiral flow channel with rotational symmetry, so that the dusty airflow entering the cyclone separator axially generates strong rotation and then enters the cyclone barrel along the barrel in a spiral shape, that is, the dusty airflow moves downward along the outer space of the separator while making rotational movement. In the downward movement process, due to the difference of the magnitude order of the density of the gas phase and the solid phase, compared with the air flow, the solid particles move towards the cylinder wall under the driving of larger centrifugal force, and are brought to the lower cone 2 by the downward air flow (outer rotational flow) after reaching the cylinder wall, so that most particles in the dust-containing air flow are removed preliminarily. Under the condition that the cross-sectional area of the lower cone 2 is gradually reduced, due to the viscosity of inertia and gas, the rotating airflow for separating impurities can flow along the radial direction in the cone section, and finally, the upward secondary vortex (inner vortex) is formed in the conversion direction, and the flow process of converting the outer vortex into the inner vortex not only can cause large energy loss, but also is extremely unstable and easily causes tail end swing in the conversion process, the tail end of the inner vortex is shaken to enable particles on the wall surface of the lower cone 2 to fall off, the particles are rolled up again and slide away along with ascending airflow, and the separation efficiency is reduced.

As can be seen from fig. 6, 7, 8, 9, 10 and 11, the exhaust pipe 4 extends downward through the top axis of the upper cylindrical barrel 1, the end of the exhaust pipe 4 is sleeved with the filter member 5 formed by the protrusion 13 embedded in the filter body 12, and the triangular or hemispherical hole pattern and secondary flow channel formed by the two depends on the three-dimensional structure of the protrusion 13. From the flow trajectory, the internal swirling flow carrying the back-mixed particles flows from the inlet of the projection 13 into the flow passage of the filter member 5 (the space surrounded by the inner wall surface of the projection 13 and the outer wall surface of the filter body 12), because the inclination angle of the inner wall of the designed convex part 13 is different from the angle of the side wall of the through hole of the filtering body 12, a corner exists at the joint, and because of the density difference of two phases in the back mixing airflow, the gravity, the resistance and the friction force of the particles are all larger, that is, when the particles are stopped by the inner wall surface of the convex portion 13 to obtain the reverse acceleration and the inertia force of the particles moving along with the air flow is developed to be smaller than the resistance, the particles fall off from the inner vortex, the separated particles move along the outer wall of the filter body 12 towards the side wall of the lower cone 2, the pure inner vortex easily keeps stable movement track and speed, and the particles move into the exhaust pipe 4 through the through hole formed in the filter body 12 and are then discharged from the outlet 102 to be utilized. The structure not only inhibits the loss caused by the negative pressure suction at the center of the bottom of the cylinder body, but also enables the back-mixed particles to fall back to the wall surface of the lower cone 2, thereby achieving the purpose of improving the efficiency and the low resistance.

The diversion cone 6 is a solid inverted cone and is connected with the bottom end of the filtering component 5. After the process is completed, solid particles settled by the primary separation and filtration part 5 are adsorbed on the wall surface of the lower cone 2, and the particles and the air flow (which cannot be converted into an internal vortex) are limited to move downwards by various generated vortexes because the cone section flows in the three-dimensional complex strong vortex for a long time, so that the flow guide cone 6 is additionally arranged to guide the suspended and stagnant dust-containing air flow, and the downward flow smoothly reaches the secondary separation unit B. This setting not only reduces the back mixing probability, also simplifies the vortex flow that 2 inner chambers of lower part cones are complicated for more complicated torrent is thoroughly cut apart into ascending secondary vortex and decurrent dusty air current originally, greatly improves the separation performance. Meanwhile, the upper bottom surface of the cone can limit the tail swing phenomenon of the tail end of the vortex in the filtering component by being similar to a plane vortex limiter, and the gas exhausted from the exhaust pipe 4 is ensured to be purer and the pressure loss in the circulating process is small. The structure is relatively simple, the production is convenient, the difficulty and the cost of assembly are greatly reduced, and the popularization and the utilization are convenient.

As shown in fig. 3, the second-stage separation unit B is a separation cylinder formed by fixedly connecting a cylindrical shell 7 and a conical hopper 8, the lower end of the conical hopper 8 is connected with the upper end of a dust exhaust pipe 9, the lower end of the dust exhaust pipe 9 is a discharge hole 106, and a second-stage exhaust pipe 10 is coaxially arranged with the cylindrical shell 7 and has a certain part extending into the cylindrical shell 7.

The pure gas separated by the separation unit A is discharged from the exhaust port 102 and collected for use; however, the residual particle-containing gas stream present at the end of the lower cone 2 (dust outlet 103) is introduced by the aforesaid deflector cone 6 into the connecting elbow C and enters the secondary separator via the elbow outlet end, i.e. tangential inlet 104. The secondary separation unit B receives residual particle-containing airflow, provides favorable guarantee for eliminating the phenomenon of returning or detention of particles entrained by the vortex at the bottom of the cone, and promotes the flow state of the outlet of the separation unit to tend to be stable. Similarly, the dust-containing gas flow forms a downward spiral gas flow in the circular cavity formed by the secondary exhaust pipe 10 and the cylindrical shell 7, particles with higher density are thrown to the wall by centrifugal force, fall to the discharge hole 106 of the dust exhaust pipe 9 along the side wall of the conical hopper 8 under the action of the downward gas flow, and then the gas is contracted towards the center and flows upwards into the secondary exhaust pipe 10, so that the gas subjected to thorough separation and purification is discharged from the discharge hole 105. The separation process of the second-stage separation unit B is similar to that of the first-stage separation unit A and is not described in detail, but the separation effect of the second-stage separation unit B is ideal and redundant parts do not need to be added because the gas flow entering the second-stage separation unit B is less and the solid particles move to the second-stage separation unit B completely, so that the concentration of the solid particles is higher.

The utility model discloses well separator unit A is comparatively compact with second grade separator unit B structure, and the hookup return bend C structural style of connection is single to when realizing simple structure and saving cost, make cyclone bear higher pressure, be applicable to the operating mode condition that all kinds of area high pressure and pressure attenuate gradually along with the time, satisfy the moderate and high requirement of separation efficiency of pressure drop.
