Description

A kind of square separator with two inlets import rotating channel with inner cone

Technical field

The utility model relates to a kind of square separator, particularly relates to a kind of square separator with two inlets import rotating channel with inner cone, belongs to gas-solid two and is separated and the industrial dedusting and the field of gathering dust.

Background technology

Cyclone separator is one of the most ancient gas solid separation and air sampling equipment, at many industrial circles, has a wide range of applications as the energy, environmental protection, chemical industry, light industry and metallurgy etc.Its performance parameter changes with its design parameter (shape, size) and operational factor (flow velocity etc.).At present, cyclone separator is lower with respect to efficient deduster such as cloth bag, static less than the fine grain classification efficiency of 5～10 μ m for aerodynamic diameter: be difficult to adapt to the development of many industrial circles and environmental protection.For cyclone separator, its internal structure plays an important role to raising the efficiency, reduce resistance, simultaneously again can not be too complicated, otherwise be unfavorable for design processing and engineering application.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of square separator with two inlets import rotating channel with inner cone, to remedy the deficiencies in the prior art or defective, meets the demands of production and living.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of square separator with two inlets import rotating channel with inner cone, comprise import, cylindrical shell 3, ash bucket 6, exhaust core pipe 2 and ash discharging hole 7, described import is the two inlets import, comprise left cut to import 1 ' and right cut to import 1, exhaust core pipe 2 is positioned at the center of cylindrical shell 3; Left cut is to import 1 ' be connected with cylindrical shell 3 horizontal tangentials respectively to import 1 with right cut, and the bottom of cylindrical shell 3 and square diffuser 4 are fixed together with " hemispherical dome ", and the lower end of square diffuser 4 and ash bucket 6 are affixed, and the bottom of ash bucket 6 is connected to ash discharging hole 7; Be provided with reflection cone 5 in square diffuser 4 bottoms, reflection cone 5 tops are provided with air-vent, and the bottom links to each other with ash bucket 6 by dowel.

As optimized technical scheme: left cut to import 1 ' and right cut be the center symmetrical distribution to import 1 with cylindrical shell 3.

Described reflection cone 5 is for falling infundibulate.

The utility model is work like this: after dust-contained airflow enters separator, rotation enters square diffuser 4 downwards, when arriving the bottom, because the effect of reflection cone 5, most of air-flow is turned back and is upwards discharged by exhaust core pipe 2, a small amount of air-flow near the barrel of cylindrical shell 3 advances people's ash bucket 6 in company with dense poly-dust along the slit between square diffuser 4 lower edges and the reflection cone 5, after dust separation, gas is upwards discharged from reflection cone 5 top air-vents, fail to be convened for lack of a quorum with the inward turning that rises and to close the back by exhaust core pipe 2 drain separators, dust is discharged from ash discharging hole 7.

The beneficial effects of the utility model are: the structure of the square separator with two inlets import rotating channel of band inner cone, by reducing the inlet flow velocity of separator, utilize its tangential entry rotating channel to the disturbance of air-flow and reflection cone advantages such as reflex to air-flow, to solve in the prior art for the low shortcoming of fine grain classification efficiency less than 5～10 μ m, raising is to the separating power of particle, shorten particle to separation and collection wall move distance, improve separating effect, reduce exhaust and take dust quantity, thereby improve the performance of separator.

The specific embodiment

Below in conjunction with specific embodiment the present invention is done further and to elaborate.

Embodiment 1

With reference to accompanying drawing 1-2, a kind of square separator with two inlets import rotating channel with inner cone comprises import, cylindrical shell 3, ash bucket 6, exhaust core pipe 2 and ash discharging hole 7, and described import is the two inlets import, comprise left cut to import 1 ' and right cut to import 1, be center symmetrical distribution with cylindrical shell 3.Exhaust core pipe 2 is positioned at the center of cylindrical shell 3; Left cut is to import 1 ' be connected with cylindrical shell 3 horizontal tangentials respectively to import 1 with right cut, and the bottom of cylindrical shell 3 and square diffuser 4 are fixed together with " hemispherical dome ", and the lower end of square diffuser 4 and ash bucket 6 are affixed, and the bottom of ash bucket 6 is connected to ash discharging hole 7; In square diffuser 4 bottoms funnel shaped reflection cone 5 is housed down, reflection cone 5 bottoms link to each other with ash bucket 6 by dowel, and top is provided with air-vent, and reflection cone 5 bottoms link to each other with ash bucket 6.

Found through experiments, separator described in the utility model is for the bigger glass dust of particle diameter, and separative efficiency is substantially more than 99.5%, and increases along with the increase of speed.The discovery of comparing with discharge air separator under the diffusion type of circular section, separator described in the utility model just has higher separative efficiency under lower speed, the flow velocity that arrives best efficiency point is also lower, its reason, the one, the square-section helps producing eddy current four corners, increase the touch opportunity of particle, impel fine grained to reunite into bulky grain or attached on the bulky grain: the 2nd, the existence in little whirlpool, corner also can consume the kinetic energy of particle, makes its sedimentation under the gravity effect; The 3rd, the break-in rapidly of edge air-flow not only has centrifugal action to also have effect of inertia to particle, thereby has improved efficient.In addition, the classification efficiency of separator described in the utility model increases with the increase of particle diameter.
