Cyclone dust collector
The advantages of dragon environmental protection cyclone dust collector:
1. cyclone dust collector is simple in structure, low in cost, small in size and convenient in maintenance;
2., small resistance, large amount of air handling, dust removal efficiency, up to about 90%;
3. can handle the significant particle dust of 5um-10um;
4., when dealing with large air volume, it is convenient for parallel use of many units, and the efficiency and resistance are not affected;
5. simple and easy fast effect, no wearing parts etc.;
More than 6. choice models include high temperature resistant, moisture proof, flame retardant and so on;
I. definition of cyclone dust collector:
Cyclone dust collector is a kind of dust removal device. In addition to sink mechanism is to make the dusty flow to rotate by means of centrifugal force to dust from the air separation and trapping in the wall, with the gravity of the dust particles into the hopper.
Two, working principle:
Dusty gas imports from entering the cyclone along the tangential direction, along the wall from the top down rotation, the rotating downward airflow is called vortex (outer vortex), outer vortex reach cone bottom to upward along the axis of rotation, and finally through the discharge tube. The upward swirling gas flow is called the inner vortex (inner vortex). The direction of rotation of outer vortex and vortex in the same dust airflow rotates, dust particles in the inertial centrifugal force pushing down to the outer wall, the outer wall of the dust particles reach the common role in air and gravity along the wall into ash hopper to achieve purification. When the air flow down from the top of the dust collector, the pressure at the top drops, and a part of the airflow will rotate along the outer wall with fine dust particles. When it reaches the top, it will spin out along the discharge pipe and discharge from the exhaust pipe.

Three. Technical introduction
When the air stream rotates, the dust particles in the air stream are separated from the air stream by centrifugal force. The technique of removing dust by centrifugal force is called centrifugal dust removal technology. A device that uses centrifugal force to remove dust is called a cyclone.
In the cyclone, the air flow in the cyclone rotates repeatedly, and the rotation speed of the air flow is very fast. Therefore, the particles in the swirling flow are subjected to centrifugal force, and the specific gravity is increased greatly. For a small diameter, high resistance rotary dust filter, the centrifugal weight can be as large as 2500 times. For large diameter and low resistance dust collector, the centrifugal ratio is 5 times larger than the gravity.
Advantages of cyclone dust separator products:
The device structure has the advantages of small size, simple structure, small occupation area, low cost, small resistance, large air handling;
The rotating mechanism and no moving parts, convenient maintenance and management, without the technical requirements;
It can be used for purifying dust gas of high temperature cyclone dust collector, general carbon steel can be used for 100 DEG C for flue gas purification. The cyclone dust collector with inner wall refractory material can be used for the treatment of flue gas at 500 degrees centigrade;
The dry cleaning, is conducive to the recovery of valuable dust at;
The application of a wide range of dust collector in laying wear resistant and corrosion resistant lining, can be used to purify the gas with high dust corrosion.
Disadvantages of cyclone dust separator products:
A cyclone dust collector for separating dust density, coarse grain size, the dust is less than 5 m and fibrous dust, trapping efficiency is very low;
The single cyclone air volume is limited, when the volume required multiple parallel;
It is not suitable for the purification of disc sticky dust.
Explain£º
The design and operation, should pay special attention to prevent the bottom leakage so as to avoid the decline of pride, the efficiency of a dust collector;
In parallel, to try to make the cyclone air the same;
In the dust removal system, cyclone dust removal device is usually used or spark trap, sometimes plays the role of material.
Applicable range of cyclone dust collector:
Mainly applies to: dust purification hardware, furniture, building materials, cement, ceramics, chemicals, footwear, casting, aluminum products, metallurgy, machinery, nonferrous metals and other industrial fields.
