Working principle of cyclone dust collector in printing and dyeing sludge drying equipment production line

Classification of cyclone precipitator in printing and dyeing sludge drying equipment production line

From the technical point of view, cyclone dust collector can be divided into dry type and wet type. Dry dedusting: dust falls into ash hopper due to its own gravity after separation. Wet dust removal: the dust is wet by liquid and falls into the ash hopper. Due to the higher efficiency of wet dust removal, there is no possibility of secondary dust, so wet dust collector is commonly used in the market. From the structure point of view, the cyclone dust remover has double drum type, multi tube type, mother and son type, etc. Although there are many types of equipment, they can not be separated from each other. The basic principle of cyclone dust removal is the same.

Working principle of cyclone in the production line of printing and dyeing sludge drying equipment

By using the rotating airflow to separate the dust from the air under the action of centrifugal force, 5 ~ 10 um dust particles can be treated. For the dust removal of small particles (such as 0.1 micron), the bag filter can be added in the production line of printing and dyeing sludge drying equipment.

After the dust containing gas enters into the cyclone dust collector, the air flow changes from linear motion to rotary motion. The dust has a strong separation effect at the boundary of the air flow spiral volute, and the particles with higher density fall into the ash discharge pipe due to the loss of inertia. At this time, the swirling flow continuously drops. When the cone reaches the cone, the gas flows to the middle of the dust collector due to the downward contraction of the cone. When it reaches a certain position, the gas flows to a certain position In the same direction, the spiral worm movement will continue from bottom to top from the middle of the dust collector until the top is discharged through the exhaust pipe.

The above is the basic working principle of the cyclone dust collector in the production line of printing and dyeing sludge drying equipment. The equipment is low cost and easy to operate. It is often used to treat the high-temperature waste gas discharged from the printing and dyeing sludge drying equipment. However, the equipment is based on the principle of inertia separation of dust particles. The power of dust removal is proportional to the particle size. The dust removal effect is good for the waste gas with large particle size and the dust with small particle size It's a little difficult. With more and more strict environmental protection policies, I believe that the dust removal technology and process of waste gas treatment equipment will continue to improve, and equipment with higher dust removal power and better effect will appear in the future.
