It is essential that air, which carries out effective dust removal process,.Currently, it is to utilize to apply most common dedusting method in ventilating system
Filter is filtered dedusting to air.Dust removal by filtration mode has many advantages, such as 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 leads to higher operating cost etc..
Cyclone dust collectors, which are one kind, can utilize self structure that fluid is made to generate rotary motion, and be generated 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
It sets.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 recycling, environmental protection are more and more widely used.
Utility model content
The purpose of this utility model is just to provide that a kind of pressure drop is small, separative efficiency is high using single flow cyclone separator
Dust-extraction unit.
A kind of dust-extraction unit using multistage DC cyclone separator combination array, it is characterised in that：Including shell, shell
There is air inlet, the other end to be equipped with exhaust pipe for one end；Several single flow cyclone separator arrays are also arranged in shell in an axial direction, often
One single flow cyclone separator array is rearranged by several single flow cyclone units；Above-mentioned single flow cyclonic separation
Device unit is a hollow cylinder, and inner port has guide vane, guide vane to be fixed in single flow cyclone unit
On wall, there is the unit exhaust pipe that a diameter is less than single flow cyclone unit in exit, and unit exhaust pipe root is using gradually
Expand arc transition, the region gone out folded by unit exhaust pipe and single flow cyclone unit inner wall is unit dust discharge channel；Directly
The irrigation canals and ditches shape channel that the flaring arc transition section of adjacent cells exhaust pipe is constituted in streaming cyclone separator array is known as dust discharge ditch；
Dust flue is installed along central axes in shell, 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；Exhaust pipe installs scavenger fan.
The working method of the dust-extraction unit using multistage DC cyclone separator combination array, it is characterised in that packet
Include following procedure：Dust-contained airflow enters from air inlet in device；Most dust-contained airflows enter under the action 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 acting on for blade, and the larger dust of density tends to single flow whirlwind under the action of inertia in dust-contained airflow
The internal face of separator unit, then unit dust discharge under the action of dust exhausting fan out of single flow cyclone unit is logical
The dust discharge ditch being discharged into road in single flow cyclone separator array enters dust flue along dust discharge ditch；Clean gas flow is being arranged
Next stage single flow cyclone separator array is discharged under the action of air fan from unit exhaust pipe；Another fraction dust-laden
Air-flow is directly entered in the dust flue at single flow cyclone separator array center, under the action of dust exhausting fan, and from each
The higher gas confluence of dust concentration being discharged in single flow cyclone separator array, goes out through dust discharging tube outside device.
The main feature of the utility model includes：The pressure loss is smaller.Compared with traditional cyclone dust collectors, can significantly it drop
Rubbing action between low-flow reduces the pressure loss.The gas velocity that works is low.The gas speed that single flow cyclone dust collectors need when working
Degree is small compared to conventional cyclone.Equipment volume is smaller, and air-treatment amount is big.It is easy to several cyclone dust collectors monomers to carry out
Assembling and technology arrangement.By These characteristics it is found that single flow cyclone dust collectors are especially suitable for dust content height, air-treatment amount
Greatly, and the limited occasion in space.
The dust-extraction unit 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
It places）Come make dust to the dust flue at device center assemble, preventing dust to be gathered in single flow cyclone separator array causes
Device blocks.
The dust-extraction unit using multistage DC cyclone separator combination array, it is characterised in that：Above-mentioned single flow
Cyclone separator array from air inlet to exhaust pipe direction, including single flow cyclone unit number gradually subtract
It is small.The purpose of this design is that rear single flow cyclone separator array airflow inlet speed reduces in order to prevent.Ugly gas
Stream often after level-one single flow cyclone separator array all can some air-flow enter in dust flue with dust, if often
The single flow cyclone separator number of level-one is all suitable, then air velocity can then reduce step by step, the reduction of air velocity will
Seriously affect the performance of the separative efficiency of single flow cyclone separator.
