Part of the dust collector principle of cyclone scrubbing dust collector

A dust collection hood is set up in each ash place, and the dust-containing gas is transported to the dust removal device through the pipeline gas path, in which the dust is collected in the dust removal device after the gas-solid separation is carried out, and the clean gas is introduced into the main pipe or directly discharged into the whole set of equipment into the atmosphere, that is, the dust removal system, and the dust collector is an important part of the system. From the perspective of ventilation and dust removal, dust is all solid small particles that can float in the air for a long time, and is a dispersion system, called aerosol, in which air is the dispersed medium and solid particles are the dispersed phase. A dust collector is a device that separates these small solid particles from aerosols.

Briefly describe the dust removal process in the cyclone dust collector, the working process of the cyclone dust collector is that when the dust-containing gas enters the cyclone separator from the tangential air inlet, the air flow will change from linear motion to circular motion. The vast majority of the rotating airflow flows along the wall of the vessel from the cylinder in a spiral downward toward the cone, which is often referred to as exocyclotronic airflow. The centrifugal force generated by the dusty gas during rotation throws dust particles with a relative density greater than the gas towards the wall of the device.

Once the dust particles are in contact with the wall, they lose the radial inertial force and fall along the wall by downward momentum and downward gravity and enter the ash discharge pipe. When the swirling descending external gas reaches the cone, it moves closer to the center of the collector due to the contraction of the cone. According to the principle of invariant "rotational moment", the tangential velocity continues to increase, and the centrifugal force on the dust particles also increases.

When the air flow reaches a certain position at the lower end of the cone, it will turn from the middle of the cyclone separator in the same direction of rotation from the bottom to the top, and continue to do spiral flow, that is, the internal spiral airflow. Finally, the purified gas is discharged out of the pipe through the exhaust pipe, and a part of the dust particles that have not been collected are also discharged. Hope it helps!

<> cyclone dust collector is a kind of gas-solid separation device that uses the centrifugal force generated by the rotating dust-containing gas to separate the dust from the gas stream. It has high efficiency in capturing and separating dust above 5 10mm, so it is widely used in chemical industry, petroleum, metallurgy, light industry and other industrial sectors.

1. Working principle:

When the dusty air flow enters the bag filter from the air inlet pipe at a speed of 12 25mm s, the air flow will change from linear motion to circular motion. The vast majority of the rotating airflow flows downward in a spiral shape from the cylinder (i.e., the external cyclone airflow) along the wall of the vessel towards the cone. The dusty gas generates centrifugal force during rotation, throwing dust particles that are denser than the gas against the wall of the device.

Once the dust particles come into contact with the wall, they lose their inertial force and fall along the wall by the momentum of the inlet velocity and the downward gravity and enter the ash discharge pipe.

The swirling descending external cyclone air flow is approached to the center of the collector by conical contraction as it reaches the cone. When the air flow reaches a certain position at the lower end of the cone, it continues to spiral flow from the middle of the dust collector from bottom to top in the same direction of rotation, that is, the internal rotation airflow. Finally, the purified gas is discharged through the exhaust pipe, and a part of the dust particles that have not been caught are also lost.

2. Features: The structure is simple, there are no moving parts in the body, no special auxiliary equipment is required, the area is small, and the investment in manufacturing and installation is less.

It is easy to operate and maintain, the pressure loss is medium, the power consumption is not large, and the cost of operation and maintenance is low.

The operation of the bomb has large spike control, stable performance, and is not limited by the concentration and temperature of the dusty gas flow. There are no special requirements for the physical properties of dust, and at the same time, according to the different requirements of chemical production, different materials can be selected to make or lined with various different wear-resistant and heat-resistant materials to improve the service life.

The cyclone dust collector uses centrifugal force to remove dust, and when the dust-containing air flow enters the cyclone dust collector from the air inlet pipe, the air flow will change from linear motion to circular motion. Dust particles with a density greater than the gas will lose their inertia force when they contact the wall and fall along the wall surface and enter the ash discharge pipe.

When the swirling descending exocyclone air reaches the cone, it moves closer to the center of the collector due to the contraction of the cone. When the air flow reaches a certain position at the lower end of the cone, it continues to flow in a spiral shape from the middle of the cyclone dust collector from the bottom to the top in the same direction of rotation. Finally, the purified gas is discharged through the exhaust pipe.

Introduction: In some large factories in Changchao, there will be a cyclone dust collector, which is a dust removal device, the principle is to use the air flow to rotate the movement, and use centrifugal force to suck the dust into the machine along the air flow, so that the dust enters the ash hopper. Today I would like to introduce to you the knowledge about cyclone dust collectors.

First, the first or brief introduction of the cyclone dust collector.

The use of cyclone dust collectors was in the 80s of the 19th century, when there were two types of cyclone dust collectors: one tangential and the other axial entry. At the same pressure, the axially entry airflow is relatively uniform.

The components of the cyclone dust collector are: air intake pipe, exhaust pipe, cylinder and ash hopper. Its structure is simple, easy to install and maintain, and modern cyclone dust collectors can separate solid and liquid ions.

Among the mechanical dust collectors, the cyclone dust collector has the highest efficiency.

Second, the advantages of cyclone dust collector.

The smaller the short-circuit flow, the higher the dust collection efficiency. The effect of not the full-length resistance rod is not as good as the effect of the full-length resistor rod, and the efficiency of the cyclone dust collector can be improved by reducing the short-circuit flow and lowering the cross-section.

3. Classification of cyclone dust collectors.

1. The high-efficiency cyclone dust collector has the characteristics of small cylinder and high dust removal rate.

2. The cyclone dust collector with large flow rate is characterized by a large cylinder but low dust removal rate.

3. Explosion-proof cyclone dust collector, the machine has explosion-proof measures and has a strong explosion-proof function.

4. The general-purpose cyclone dust collector is characterized by the average dust removal rate, but the most commonly used cyclone dust collector.

According to the different forms, the classification is also different:

1) Classified according to structure: cylindrical, vertebral, diffuse ......

2) According to the classification of airflow: and stay flip dust collector and axial flow dust collector.

3) Classified according to the combination: inner cyclone Xunwu type, outer cyclone type, vertical and horizontal cyclone dust collector.

4. Factors affecting the efficiency of cyclone dust collector.

1. Air intake. The air inlet is an important component in the whole dust collector, and it also affects the dust collection efficiency. The smaller the area of the air inlet, the greater the airflow velocity, and the higher the dust removal efficiency, which is more conducive to the separation of dust from other things.

2. The diameter and height of the cylinder affect the efficiency of the machine. The rotating air velocity is the same, and the larger the diameter of the cylinder, the smaller the centrifugal force of the air flow on the dust, and the lower the dust removal efficiency, which is not easy to be sucked into the machine. Therefore, the diameter of the air inlet of the dust collector is not easy to be too large, and the air inlet should not be too small, if the dust particles are large, the air inlet may be blocked.

3. The diameter and depth of the exhaust pipe also affect the dust removal efficiency. The diameter of the exhaust pipe mouth is small, the airflow is small, and it is difficult for dust to be discharged from the exhaust pipe, so it is necessary to speed up the air outlet and increase the diameter.

Cyclone dust collector is a must-have item in our usual factory, have you ever had a detailed understanding of it, I hope to help you choose the kind of cyclone dust collector you need.

You can get it for free

The ordinary cyclone dust collector is composed of four parts: inlet, simplified, cone, and discharge pipe (inner cylinder).

The cyclone dust collector uses the centrifugal force generated by the rotation process of the air flow to separate the dust from the dusty air stream. After the dust-containing air flow enters the dust collector from the inlet of the dust collector in the tangential direction, it rotates downward along the outer wall, and this downward rotating air flow is called the outer vortex. Once the outer vortex reaches the bottom of the cone, it turns upwards, rotates upwards along the axis, and finally exits from the discharge tube.

This upward air flow becomes an internal vortex. The downward outer vortex and the upward inner vortex rotate in the same direction, i.e., uniformly clockwise or counterclockwise. When the air flow does a rotational motion, the dust is thrown to the outer wall under the action of centrifugal force, and the dust reaching the outer wall falls into the ash hopper along the wall surface under the combined action of the downward spiral air flow and gravity.

The working principle and advantages and disadvantages of cyclone dust collector!

Components: inlet, simplified, cone, discharge pipe.

Principle: The cyclone dust collector uses the centrifugal force generated by the rotation process of the air flow to separate the dust from the dusty air stream. The dust is thrown to the outer wall under the action of centrifugal force, and the dust that reaches the outer wall falls into the ash hopper along the wall surface under the combined action of the downward cyclone air flow and gravity.
