Description

A kind of double volute formula tornadotron that makes up the structure of cracking that has

Technical field

The utility model relates to a kind of double volute formula tornadotron that makes up the structure of cracking that has, and belongs to the device that the mode of solid phase in the gas or liquid phase impurity employing centrifugation is separated.

Background technology

Existing double volute formula tornadotron is because import is a worm frame, and gas-solid to be separated or gas-liquid mixture have tentatively obtained separating in spiral case, so separative efficiency is higher; Air-flow is less in the loss of separator tube internal resistance, so pressure drop is less.But the exhaust structure of existing double volute formula tornadotron is a straight-run of pipe, near blast pipe, there is serious radial centripetal air-flow, it is short-circuit flow, short-circuit flow can just be taken solid particle out of blast pipe when separating as yet, cause separative efficiency to descend, bigger in addition particle spring can make it escape from blast pipe, though cause this kind double volute formula tornadotron gas-liquid separation efficient higher, gas solid separation efficient is lower.Therefore, reach and improve the higher purpose of double volute formula tornadotron efficient, must improve the structure of blast pipe, to reduce the influence to separative efficiency of short-circuit flow.

The utility model content

It is lower that the utility model purpose is to solve existing double volute formula tornadotron separative efficiency, and particle is because the problem that the existence of the terminal short-circuit flow of blast pipe is escaped from the mouth of pipe.

A kind of double volute formula tornadotron that makes up the structure of cracking that has of the utility model comprises separator tube, blast pipe and ash bucket; The blast pipe lower end connects shunting core tube, and this shunting core tube structure is characterized in that double volute formula tornadotron blast pipe lower end installation shunting core tube for having on it along the cone of the even distributed combination seam of axis direction; Have the slit along axis direction on the shunting core tube, its top is vertical masonry joint, and the bottom is a R-joining; There is the awl cover that is connected as a single entity the cone lower end, and the cone lower end is a free end; The separator tube bottom is the dust discharge awl that connects as one, and sealing is installed in the ash bucket; Blast pipe, shunting core tube and the coaxial installation of separator tube.

A kind of double volute formula tornadotron that makes up the structure of cracking that has of the utility model.Slit on the shunting core tube is the combination of two kinds of types of cracking, slit is oblique at an angle from outside to inside offering, this angle is a slit perpendicular to the center line in the plane of axis with by the angle between the diameter of this center line and excircle intersection point, the angle of offering of the vertical masonry joint on top is 0, its width is 1mm, and the vertical masonry joint height is 0.1～0.3 times of shunting core tube height; The angle of offering of the R-joining of bottom is an a certain value between 0 ° to 90 °, and its width is 2.5mm, and the R-joining height is 0.5～0.7 times of shunting core tube height; The slit gross area and core infratubal port area sum be greater than the blast pipe area on the shunting core tube, and the ratio of open area is 0.5～0.9 under the vertical masonry joint gross area and the shunting core tube, and the R-joining gross area is 0～5 with the ratio of shunting core tube lower port area; The following bore of shunting core tube upper conical cover enlarges, and cone angle is 40 °～80 °; Dust discharge awl cone angle is 15 °.

A kind of advantage and good effect that has the double volute formula tornadotron that makes up the structure of cracking of the utility model is: because the vertical masonry joint on the shunting core tube is offered perpendicular to axis direction, air-flow is introduced into blast pipe in advance, reduce the flow resistance of air-flow, thereby reduced pressure drop; Because the R-joining on the shunting core tube is offered at a certain angle, after liquid phase that air-flow to be separated carries or solid phase particles moved to herein, because the existence of gas-liquid or gas-solid two-phase density contrast, liquid phase or solid phase particles obtained inertial separation, increased separative efficiency; The shunting core tube slit gross area and core infratubal port area sum are greater than the blast pipe area, the circulation area of air-flow is increased, not only having guaranteed has enough air-flow spin intensity and separative efficiency in the pipe, and has reduced the flow resistance of air-flow, thereby reduces pressure drop; The shunting core tube lower end is made as the awl cover of one, makes through the high turbulence pulsation of effluent stream herein to be suppressed, and has weakened the radial motion of air-flow, has reduced the short-circuit flow loss, increases separative efficiency significantly, cuts down the consumption of energy.

The specific embodiment

By Fig. 1, Fig. 2, shown in Figure 3, a kind of double volute formula tornadotron that makes up the structure of cracking that has of the utility model comprises separator tube (2), blast pipe (9) and ash bucket (4), blast pipe (9) is installed in the top of separator tube (2), both are coaxial, blast pipe (9) lower end is provided with the shunting core tube (8) that is connected as a single entity, and lower port is dwindled, and its upper edge axis direction has the slit (6,7) of some equably, and shunting core tube (8) lower end is provided with the awl cover (5) that is connected as a single entity.Separator tube (2) lower end is installed in the ash bucket (4) to i.e. dust discharge awl (3) sealing.

Slit on the shunting core tube (8) (6,7) is oblique at an angle offering from outside to inside, this angle is a slit (6,7) perpendicular to the center line in the plane of axis with by the angle between the diameter of this center line and excircle intersection point, the angle of offering of the vertical masonry joint on top (7) is 0, its width is 1mm, and vertical masonry joint (7) highly is 0.1～0.3 times of shunting core tube (8) height; The angle of offering of the R-joining of bottom (6) is an a certain value between 0 ° to 90 °, and its width is 2.5mm; Shunting core tube slit (6, the 7) gross area and core infratubal port area sum are greater than blast pipe (9) area, vertical masonry joint (7) gross area and shunting core tube (8) ratio of open area down are 0.5～0.9, and the ratio of R-joining (6) gross area and shunting core tube (8) lower port area is 0～5; The following bore of shunting core tube (8) lower end awl cover (5) enlarges, and cone angle is 40 °～80 °; Dust discharge awl (3) cone angle is 15 °.
