Working principle of cyclone dust removal equipment

Working principle of cyclone dust collector

The cyclone dust collector uses the centrifugal force generated by the rotating airflow to separate dust particles from the airflow mixed with dust.

Take it out of the dust removal device. It has the advantages of simple structure, small volume,

No need for special auxiliary equipment, low cost, moderate resistance, no moving parts in the device, and convenient operation and maintenance.

Cyclone dust collectors are generally used to collect particles above 5- 15 micron.

The dust removal efficiency can reach more than 80%,

Special cyclone dust collector improved in recent years.

Its dust removal efficiency can reach more than 5%.

The disadvantage of cyclone dust collector is that the efficiency of collecting particles smaller than 5 microns is not high.

General situation of airflow and dust particle movement in cyclone dust collector;

Most of the rotating airflow spirally moves from the cylinder to the bottom of the cone along the wall of the device, forming a downward external rotating dusty airflow, and the centrifugal force generated in the process of violent rotation throws dust particles whose density is much higher than that of gas to the wall of the device.

Once the dust particles touch the wall, they disappear.

The entrance velocity and the momentum of its own gravity drop along the wall and enter the ash hopper without inertia force.

After the downward rotating airflow reaches the bottom of the cone, it turns upward along the axis of the cleaner, forming an upward internal rotating airflow, which is discharged from the exhaust pipe of the cleaner. Another small part of the air flow from the air inlet,

Then flow to that top cover of the cyclone dust collector, then flow downwards along the outer side of the exhaust pipe, and when reaching the low end of the exhaust pipe,

That is, it reverses upward and is discharged from the air duct together with the rising central airflow, and the dust particles dispersed in it are also taken away.

Hello! Vacuum cleaner customization expert:? 02 1-64779658

Custom vacuum cleaner, I suggest looking for a manufacturer with experience in custom vacuum cleaner, because this will reduce your time cost and give you a lot of advice on custom vacuum cleaner.

Vacuum cleaner, not to mention before, is a common vacuum cleaner. Now the living standard has improved, and most of them are imported vacuum cleaners. This can increase the sales of vacuum cleaners. Employees often suggest that they should switch to imported vacuum cleaners. We also tried to change a lot of imported vacuum cleaners. As a result, the sales volume is very large! Later, I made a comprehensive customized plan for imported vacuum cleaners. We have cooperated with this manufacturer for 4 years, and there is no quality problem!

Personal suggestions on vacuum cleaner selection:

The first three points are the same as yours, quality assurance, safety certification and factory direct sales.

These three points are just to reassure us, product guarantee makes us less worried, and safety certification lets us know that the product is ok, the manufacturer's production efficiency is fast, and a lot of costs are saved. Subtract many intermediate links.

Personally, the most important thing is that the vacuum cleaner should adapt to your work station, which is the most important; And use environmentally friendly materials to make consumers feel more at ease!

Personal advice:

In this regard, as long as you are not from remote areas or Tibet, I suggest you find a factory in Shanghai, which is the base of vacuum cleaner manufacturers. Through logistics transportation, you can receive the goods in a few days! We chose "pulse-opening dust collector". Worth choosing. Since 20 10, there have been no safety and quality problems. The effect after vacuumizing is also very good!
