The utility model discloses a defogging device can be avoided blockking up, and the separation has fine effect to solid particle, adopts centrifugal separation, but the size of greatly reduced equipment reduces the investment of equipment, and to high pressure vessel, the advantage is more obvious very much.
Description
Technical field
This utility model is related to the technical field of gravity type gas-liquid separation, more particularly to a kind of centrifugal gas-liquid demister.
Background technology
Fail the less oil droplet for removing in gs-oil separator gravity settling section, need to be removed using demister.Grind at present
Study carefully effect of the scholar to demister particularly to pay attention to, it is believed that gas liquid carrying rate depends primarily on the quality of demister, good removes
Mist device can reduce the gas flow area of gravity settling section and the overall dimensions of separator.Jing after gravitational settling, institute in gas
The oil droplet size of carrying should be less than 150～500 microns, and conventional demister separates this with coalescence principle to collide from air-flow
Plant little oil droplet.That what is commonly used in engineering has silk screen demister and a board-like demister, but silk screen demister be easily blocked and
Demisting efficiency is not high, therefore, it is badly in need of exploration and is related to new defogging equipment to meet the needs of existing production.
Utility model content
This utility model provides a kind of centrifugal gas-liquid demister, solves the problems, such as that existing apparatus are blocked, while can be with
Solid particle is effectively removed, the efficiency of separator is further improved.
This utility model can be achieved through the following technical solutions：
A kind of centrifugal gas-liquid demister, including cylinder, the cylinder top is provided with gas outlet, and bottom is provided with blowdown
Mouthful, bottom is provided with air inlet, in the inner barrel demister is detachably provided with the bottom of by, and the demister includes
Multiple helical blades, one end of each helical blade is welded on cover plate, and the other end most inner side is welded on Rotary-table
Rotary-table is supported on cylinder inner side by edge, the Rotary-table by lacing wire, and between the Rotary-table lower edge and cylinder gap is left.
Further, the helical blade is uniformly circumferentially disposed along the Barrel alignment.
Further, position of the air inlet on cylinder is not higher than the position of the relative cylinder of the cone lower edge.
Further, outer diameter of a circle of the cover plate diameter not less than helical blade composition.
This utility model is beneficial to be had technical effect that：
The demister, is avoided that blocking, and has good effect for solid particle is separated.Centrifugal point is adopted simultaneously
From, the size of equipment can be substantially reduced, the investment of equipment is reduced, especially for high-pressure bottle, advantage becomes apparent from.

Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.
As shown in figure 1, demister structural representation of the present utility model.The demister is using welding type or detachable
Formula is connected with equipment barrel 1, and the demister includes cover plate 2, helical blade 3, Rotary-table 4 and lacing wire 5.Helical blade 3 is along cylinder
The centrage of body 1 is uniformly circumferentially disposed, and the helical blade 3 is welded into an entirety with cover plate 2, and the size of cover plate 2 is according to blade
Depending on circumferentially disposed size, outer diameter of a circle of its diameter not less than the composition of helical blade 3.The lower limb of the helical blade 3
Heel inner side and edge welding on Rotary-table 4, while Rotary-table 4 also functions to the effect of support helix blade 3.The lower edge of Rotary-table 4 is led to
Cross lacing wire and Rotary-table is supported on into the inner side of cylinder 1, between the Rotary-table lower edge 4 and cylinder 1 gap is left, play the work of discharge opeing
With.
As shown in Fig. 2 operation principle of the present utility model is as follows：Gas-liquid mixture fluid passes through vertical separator gravitational settling
Section, isolates the droplet particles more than more than 100 microns.The drop less than 100 microns carried in gas, by under cylinder 1
Portion enters the Rotary-table 4 of the demister being arranged on inside Membrane Separator Cylinder for CFB Boiler by the air inlet 6 at bottom, and the one side of Rotary-table 4 is played
The effect of circulation area is reduced, while the flow velocity for increasing centrifugal force and needing.While the liquid edge after demister is separated
Rotary-table 4 flows downward, and the gap between Rotary-table 4 and equipment barrel 1 is flowed out, and is discharged by the sewage draining exit 7 of the bottom of cylinder 1
Outside cylinder 1.Fluid is entered and makes rotation component area after cone 1, and the region is made up of many helical blades 3, and fluid is by spiral shell
Vane piece 3 is divided into N number of region, and in each region, fluid produces centrifugal force, the larger stream of density ratio by helical blade 3
Body is thrown toward wall, flows out so as to the gap between Rotary-table 4 and equipment barrel 1.And the lighter fluid of density ratio, for example
Gas is flowed up, and equipment is flowed out in the gas outlet 8 along the top of cylinder 1.
Such as gas liquid content require it is tighter in the case of, while we can also again set above centrifugation demister
Two grades of demisters are put, for example with silk screen demister, after centrifugal demister, the probability of blocking drops significantly
It is low.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely illustrative of, and on the premise of without departing substantially from principle of the present utility model and essence, these embodiments can be done
Go out various changes or modifications, therefore, protection domain of the present utility model is defined by the appended claims.
