Description

Use the dust arrester and method of multistage DC cyclone separator combination array
Technical field
The present invention relates to a kind of dust arrester and method using multistage DC cyclone separator combination array, belong to dedusting Field.
Background technology
In order to avoid the dust in air causes to have a strong impact on to health and industrial product quality, to being sent into indoor It is essential that air, which carries out effective dust removal process,.At present, it is to utilize using most common dedusting method in ventilating system Filter carries out dust removal by filtration to air.Dust removal by filtration mode has the advantages that higher efficiency of dust collection and easy for installation, but works as room In outer air dust concentration it is larger and processing air quantity it is very big when, which will face serious problems, as plugged filter, frequently Cleaning replacement causes higher operating cost etc..
Cyclone dust collectors are that one kind can utilize self structure fluid is produced rotary motion, and are produced using rotary motion Centrifugal inertial force, the dress that the larger fluid of the density in two phase flow or solid particle are separated from one other fluid Put.The device has the characteristics that compact-sized, manufacturing cost is low, maintenance is simple, operating cost is low, flexibility is good, at present in gas The fields such as body purification, the separation of solid dirt and recovery, environmental protection obtain more and more extensive application.
The content of the invention
It is an object of the invention to provide a kind of pressure drop is small, the high dedusting using single flow cyclone separator of separative efficiency Device and its method of work.
A kind of dust arrester using multistage DC cyclone separator combination array, it is characterised in that:Including housing, housing One end has air inlet, and the other end is provided with blast pipe;Some single flow cyclone separator arrays are also arranged in housing vertically, often One single flow cyclone separator array rearranges by some single flow cyclone units;Above-mentioned single flow cyclonic separation Device unit is a hollow cylinder, and inner port has guide vane, and guide vane is fixed in single flow cyclone unit On wall, there is the unit blast pipe that a diameter is less than single flow cyclone unit in exit, and unit blast pipe root is using gradually Expand arc transition, the region gone out folded by unit blast pipe and single flow cyclone unit inwall is unit dust discharge passage;Directly The irrigation canals and ditches shape passage that the flaring arc transition section of adjacent cells blast pipe is formed in streaming cyclone separator array is referred to as dust discharge ditch; Dust flue is installed in housing interior edge axis, has a diameter larger than the diameter of single flow cyclone unit, dust flue with it is all straight The dust discharge ditch of streaming cyclone separator array is connected;Above-mentioned dust discharge pipe end is connected by a section dust discharging tube with hull outside It is logical;Dust discharging tube installs dust exhausting fan;Blast pipe installs scavenger fan.
The method of work of the described dust arrester using multistage DC cyclone separator combination array, it is characterised in that bag Include procedure below:Dust-contained airflow enters in device from air inlet;Most dust-contained airflows enter in the presence of scavenger fan Single flow cyclone unit in single flow cyclone separator array, due to water conservancy diversion in single flow cyclone unit Strong rotation occurs for the effect of blade, and the larger dust of dust-contained airflow Midst density tends to single flow whirlwind in the presence of inertia The internal face of separator unit, then the unit dust discharge in the presence of dust exhausting fan out of single flow cyclone unit are led to The dust discharge ditch being discharged into road in single flow cyclone separator array, enter dust flue along dust discharge ditch;Clean gas flow is being arranged Next stage single flow cyclone separator array is discharged into the presence of gas fan from unit blast pipe;Another fraction dust-laden Air-flow is directly entered in the dust flue at single flow cyclone separator array center, in the presence of dust exhausting fan, and from each The higher gas of the dust concentration discharged in single flow cyclone separator array confluxes, and goes out through dust discharging tube outside device.
The main feature of the present invention includes:The pressure loss is smaller.Compared with traditional cyclone dust collectors, gas can be significantly reduced Rubbing action between stream, reduce the pressure loss.The gas velocity that works is low.The gas velocity phase that single flow cyclone dust collectors need when working It is smaller than in conventional cyclone.Equipment volume is smaller, and air-treatment amount is big.It is easy to some cyclone dust collectors monomers to be assembled And technology arrangement.From These characteristics, single flow cyclone dust collectors are big especially suitable for dust content height, air-treatment amount, and The limited occasion in space.
The described dust arrester using multistage DC cyclone separator combination array, it is characterised in that:Above-mentioned single flow Cyclone separator array is the low bowl structure in the high center of surrounding.Gravity can be utilized using this structure(Assuming that device is vertical Place)To make dust assemble to the dust flue at device center, prevent dust is gathered in single flow cyclone separator array from causing Device blocks.
The described dust arrester using multistage DC cyclone separator combination array, it is characterised in that:Above-mentioned single flow From air inlet to blast pipe direction, its single flow cyclone unit number included gradually subtracts cyclone separator array It is small.The purpose of this design is to prevent what rear single flow cyclone separator array airflow inlet speed from reducing.Ugly gas Stream often after one-level single flow cyclone separator array all can some air-flow with dust enter dust flue in, if often The single flow cyclone separator number of one-level is all suitable, then air velocity can then reduce step by step, and the reduction of air velocity will Have a strong impact on the performance of the separative efficiency of single flow cyclone separator.
