Description

High-efficient inward flow filtration-type cyclone separator

The utility model relates to a kind of inward flow filtration-type eddy flow efficient cyclone, is applicable to that gas separates with solid, liquid separates concentrated, gas and the liquid of fluid separation applications and different densities and separating of liquid with solid.

Gas and solid (or liquid and solid) particle separation commonly used have inward flow filtration-type and outside filtering type, the former is that both do in the other direction or the filter type of different directions motion when filtering, the latter be both do equidirectional motion, when filtering solid particle by filter opening blocks, gas or liquid pass filter opening filter type.

Whirlwind (centrifugal) isolation of purified efficient was low during dry method was separated, and can only do thick, middle purification, and the phenomenon that often has dust and gas to discharge simultaneously causes environmental pollution and waste; Though sack cleaner or gas-solid filter can reach the smart requirement that purifies by selecting filtrate, the part filter opening is often stopped up by solid particle, needs bigger filter area, long-time continuous is used must be provided with special cleaning plant, the cost height, volume is big, and prime need be equipped with the preliminary purification device; Electrostatic precipitation cost height, the service condition harshness also needs in prime the preliminary purification device to be set.

Chinese invention patent CN1033163A discloses a kind of " bag-type whirlwind dust remover ", though this device combines cyclone dust removal and bag-type dusting, its filter bag is static, does not overcome the above-mentioned shortcoming of sack cleaner.Chinese invention patent CN1045361A disclosed " cylinder-rotating centrifugal duster " adopts the rotation inner core of perforate, but and fail to overcome the major defect of cyclone dust, can not satisfy the smart requirement that purifies.Turbulent flow dedusting in the wet dedusting and fiberglass gas wash tower, its purification efficiency still can, but water consumption is big, using has limitation, cost height, and can cause secondary pollution.

During--solid, liquid--liquid separated at liquid, precipitation method equipment needed thereby volume was big, and disengaging time is long, influences product quality; With the quiet filter method of outside filtering type and centrifugation (filtration) admittedly method is carried out liquid--when separating, filter opening can be stopped up by solid particle, can only intermittently use, and can influence the product quality or the rate of recovery.

The purpose of this utility model is to avoid the above-mentioned weak point of prior art, and provide a kind of and integrate thick, smart purification, rotational flow separation and micro porous filtration,--the inward flow filtration-type eddy flow efficient cyclone that solid, liquid--solid, liquid--liquid separates that can carry out gas.This separator separating rate is fast, separative efficiency and product yield height, good reliability.Barrel diameter is unrestricted, and highly (length) degree is little, reduces occupation area of equipment and equipment kind.The barrel wearing and tearing are little, can horizontal or vertically install.

The utility model is made up of import, cylindrical shell, filtering layer, bearing, transmission device, two outlets, discharge device, flow controller and frames, it is characterized in that being equipped with in the cylindrical shell rotor, indentation filtering layer, paddle and impeller are housed on the rotor, bearing is equipped with at the armature spindle two ends of rotor, and an end of armature spindle is connected with transmission device.

Cylindrical shell can horizontal or vertical installation on frame.The section of the indentation filtering layer of rotor can be shaped form, trapezoidal, helical teeth shape, triangle or other broken line shape form.

Optional position on barrel wall height (length) degree is provided with more than one at least import, can be arranged on the optional position on wall height (length) degree, also can be arranged on the two ends of cylindrical shell, to adapt to concrete use occasion.Cylindrical shell is provided with two outlets: materials of low density outlet and high-density matter outlet, when liquid liquid separates, in the low density liquid outlet flow controller is housed.The high-density matter outlet is contained on the barrel.

On the rotor paddle is housed when liquid liquid separates, its effect is to increase the active force of rotor to the liquid rotational flow separation.Impeller is housed as preventing that the flue gas without purification from directly entering gas vent during gas solid separation, when separator was vertically pressed dress, solid particle bottom can making and liquid were constantly shifted to outlet and are discharged by discharge device simultaneously, prevented the bottom accumulation.

On the rotor sprayer is housed during the gas solid separation that is used for the stove flue gas and allow collects wet solid particle, its effect is radially to spray vaporific water or alkali, acid solution along the whole height of rotor (length) degree, make the moistening increase quality of molecule of rotation in the cylindrical shell, and mutually easilier in the collision be condensed into bigger particle, under centrifugal force and the effect of vaporific solution radial load, arrive barrel and outlet quickly, to raise the efficiency and to reduce and discharge gas to the pollution of environment or reduce disposal cost again.

The utility model compared with prior art has following advantage:

1, separation principle of the present utility model is: have rotor rotation at a high speed under exterior power drives of indentation filtering layer in the cylindrical shell.Gas or liquid are because of the rotation at a high speed in cylindrical shell under the drive of rotor of its viscosity.The material of different densities forms layering under different centripetal force effects, outer material enters solid outlet and discharges when barrel moves to breach, finish separation process.

The rotational flow separation centripetal force of this device is to rely on the high speed rotor rotated, it or not the initial velocity that relies on gas or liquid to enter, gas or liquid in rotation speed are more much bigger than the speed of general rotational flow separation, so separative efficiency height, be not subjected to factors of affecting such as the disturbance of inlet velocity fluctuation, air-flow or solid outlet gas leakage, have operating characteristic stably.

Epitrochanterian indentation filtering layer in the utility model have broken line shape form, filtering layers such as shaped form, trapezoidal, helical teeth shape, triangle to be installed in that trapezoidal both sides (waist) are gone up and helical teeth shape, triangle, broken line shape or shaped form both sides on.When gas or liquid enter between the filtering layer of both sides, even solid particle is arranged,, can obtain centripetal acceleration near this radius of rotor because of interfloor distance is little, quality will be moved progressively outward than gas or the much bigger solid particle of liquid, leave the filtering layer space.In this device, gas or liquid enter in the rotor just to pass filter opening than low velocity change direction, so be difficult for the solid particle band is blocked filter opening to filtering layer.Even there are solids to adhere on the filtering layer, also can leave filter opening gradually because of the vibrations that big centrifugal force and rotor trace imbalance cause, reach the purpose of self-cleaning, cleaning mechanism needn't be set specially, can long time continuous working, and most solid particles littler than filter opening are discharged from outlet because of action of centrifugal force can not arrive filter opening, has higher recovery rate, this shows that this device filtration resistance is less, can select bigger filter opening for use, can reduce filter area, add that solid material can not be pressed on the filtering layer, in addition all less with the filtering layer collision, and filtrate is longer service life.

3, the utility model is not only applicable to gas-solid, liquid-solid and gas-liquid, is applicable to that also the liquid liquid of different densities separates.

The principle that liquid liquid separates is: mixing material enters cylindrical shell, paddle on the high speed rotor rotated, under the effect of helical teeth shape filtering layer and inlet velocity, liquid is in cylindrical shell and the rotation of rotor high speed, the higher liquid of density carries out layering with the lower liquid of density gradually in rotation, the former is at skin, the latter is at nexine, rotor and barrel are first Disengagement zone, near barrel is high density liquid, near rotor is low density liquid, internal rotor is second Disengagement zone, its core is the high-purity low density liquid, also is low density liquid near rotor exterior, but may has a spot of high density liquid, so second Disengagement zone also is selected district, it acts on similar centrifuge.

When this device adopted the rotor of helical teeth shape filtering layer to carry out the liquid of different densities and fluid separation applications, this not filtration of filtering layer, but a kind of control member entered speed in the rotor in order to place restrictions on not separated high density liquid.In the time will strengthening liquid in rotation speed, then on rotor, install paddle.The installing flow controller is controlled discharge rate in the low density liquid exit, guarantees not contain in the low density liquid high density liquid.
