Abstract
The utility model relates to a dust removal device for a pipeline. A flow guide member is connected with a conduit, gas-solid separating fins are fixed on the side wall of a shell, and the conduit is connected fixedly with the shell. Holes are arranged on both sides of the shell. Holes on the conduit are communicated with the holes on the shell. The gas-solid separating fins and the conduit are arranged as a concentric circle. The lower end of the shell is connected with an ash receiving tube. The dust removal device for the pipeline is used to remove solid or liquid particles entrained in the convey process of various gases containing solid particles or liquids containing liquid drops, so that the influence of dust or solid (liquid) particles on operation in subsequent steps is reduced. When the dust removal device is applied to the pipeline, the fluid entering the pipeline is rotated by a built-in structure of the pipeline, so that the fluid flows forwardly in a spiral manner. Because of large proportion, the solid particles or liquid drops move towards the wall of the pipeline under the action of centrifugal force, and when passing through a blade gap of a dust removal part, the solid particles or liquid drops move to an external interlayer and enter into a recycling system under the action of gravity.
Description
Technical field
The utility model relates to a kind of dust arrester that is used on the pipeline, belongs to the udst separation technical field.
Background technology
Existing dedusting technology mainly uses cyclone dust collectors or cloth-bag type dedusting, or uses the distortion of preceding two kinds of technology and combination to realize dedusting.
Existing deduster uses separately in the middle of system as an equipment, and its version top is straight tube, and the bottom is a pyramidal structure.Air inlet tangential direction at an upper portion thereof gets into; Form the rotation downdraught along inwall; Dwindle gradually owing to diameter in the centrum bottom; Swirling eddy contraction formation rotates up air-flow also to be passed through outside the top outlet derivation deduster, and contained dust or droplet move to the equipment outer wall under centrifugal action in the gas, and move downward entering dust collection case along wall.
Cyclone dust collectors are used for commercial production T&B, and are higher for the dust efficient that captures, separates more than the 5-10 μ m, be widely used with chemical industry, metallurgy, be have, commercial production such as building, mine, machinery, light textile.
Cyclone dust collectors have following several characteristics:
1, simple in structure, the body movement-less part does not need special auxiliary device, and floor space is less, and manufacturing, installation are invested less;
2, operation, easy maintenance, the pressure loss is medium, and power consumption is little, and the during-operation service expense is lower;
3, operating flexibility is bigger, and stable performance is not limited by gas dust content, temperature, and the dust physical property is not had specific (special) requirements, can adopt unlike materials to make according to different environments for use, or inner liner abrasive resistant, heat proof material are to improve service life.
Because the separation of cyclone dust collectors, capture are a kind of very complicated three-dimensional, two phase turbulent motions; The structure of equipment is different, the difference of physical dimension; Especially the influences such as changing factor of gas, solid two mutually differences of physical properties own, operating condition; All to cyclone dust collectors main performance---efficient, the pressure loss have remarkable influence, can't grasp its inherent characteristics of motion so far comprehensively, can't set up complete, ripe Mathematical Modeling.
Owing to there are two strands of air-flows that rotation direction is identical, the direction of motion is opposite in the cyclone dust collectors, form very complicated eddy current in it, eddy current is to the performance of cyclone dust collectors, and especially separative efficiency influences bigger.(cyclone separator detailed content can referring to " Chemical Equipment Design pandect cleaner " ISBN 7-5025-3824-0)
Sack cleaner is that the filter cloth that relies on braiding or felt to knit reaches the purpose of separating the dust in the dusty gas as filtering material.Its principle is that the effects such as screening, inertia, adhesion, diffusion and static that dust produces during through filter cloth are captured.
The sack of sack cleaner can be knitted with braidings such as natural fiber or organic synthetic fibers, glass fibre or felt and form; Used fibre diameter influences efficiency of dust collection; The more little efficiency of dust collection of diameter is high more, and maximum efficiency of dust collection can be near 100%, and serviceability temperature reaches as high as 315 ℃.
Sack cleaner is general to adopt a plurality of sacks to make up; Circular sack and flat bag are arranged, and the dust of collecting in the bag comes off it through manual work beating or mechanical oscillation mode, and the material of braiding sack needs to select according to the character of dust and the composition of gas; But can not use sack cleaner when containing material such as oils or flammable dust in the general gas; To prevent that dust from gathering burning, cause the overheated breakage of filter course, so sack cleaner has the use limitation.
As a rule; Cyclone dust collectors and sack cleaner all will occupy certain space, and cyclone dust collectors generally can be used in any position of technological process, and sack cleaner generally is used in the tail end of technological process; Its operating pressure is a normal pressure, need cut off with system when changing cloth bag and just can carry out.(sack cleaner detailed content can referring to " Chemical Equipment Design pandect cleaner " ISBN 7-5025-3824-0).
Cyclone dust collectors go into that implication speed is very big to dedusting influence, and it is poor that gas speed is crossed low dust removing effects, and the loss of gas speed excess pressure increases, and the eddy current aggravation reduces efficiency of dust collection equally; Sack cleaner generally is used in the end of technological process, and is used to have the dust separation of combustible component that the danger of burning is arranged, so its applicability has limitation.
