Dust removal equipment for slag vertical mill

Dust removal equipment for slag vertical mill

The dust removal equipment for slag vertical mill is an environmentally friendly equipment specially used to treat the dust generated by slag vertical mill in the process of processing mineral powder. The following is a detailed introduction and advantages and characteristics:

Structural composition:

• Dust collector body:

generally welded by steel plates, as the outer shell of the equipment, it plays the role of supporting and protecting the internal components, while ensuring the sealing of the equipment to prevent dust leakage.

• Filter bag:

It is the core component to realize the filtering function, usually made of high temperature resistant, corrosion resistant and breathable materials, such as needle felt. The function of the filter bag is to intercept dust and allow clean gas to pass.

• Pulse spraying device:

mainly composed of pulse valve, air bag, spray pipe, etc. Its function is to regularly spray compressed air into the filter bag to make the dust on the surface of the filter bag fall off and ensure the filtering efficiency of the filter bag.

• Ash hopper:

used to collect filtered dust. The design of the ash hopper usually takes into account the fluidity and storage capacity of the dust so that the dust can be discharged in time.

• Dust cleaning control system:

used to control the operation of the pulse jet device, automatically perform dust cleaning operations according to the set parameters, and ensure the stable operation of the dust collector.

• Inlet and outlet:

Dust-containing gas enters the dust collector from the air inlet, and the clean gas after filtering by the filter bag is discharged from the air outlet.

• Working principle:

Dust-containing gas is extracted from the slag vertical mill equipment under the action of the induced draft fan and enters the dust collector through the air inlet. Larger dust particles fall directly into the ash hopper due to gravity, and smaller dust particles pass through the filter bag with the air flow. The dust is intercepted on the surface of the filter bag, and the clean gas passes through the filter bag into the clean air chamber and is finally discharged from the air outlet. As the filtering process continues, the dust on the surface of the filter bag continues to accumulate, resulting in an increase in the resistance of the dust collector. When the resistance reaches the set value, the dust cleaning control system starts the pulse jet device, sprays compressed air into the filter bag, causing the filter bag to expand and contract instantly, and shakes the dust on the surface into the ash hopper, completing a dust cleaning process.

Advantages and features:

• High-efficiency dust removal:

The dust removal efficiency is high, which can reach more than 99.9%. It can effectively remove the fine dust particles generated during the production process of the slag vertical mill, ensure the cleanliness of the exhaust gas, and meet environmental protection requirements.

• Large air volume:

The slag vertical mill will produce a large amount of dust-containing gas during the production process. The supporting dust removal equipment can handle a large air volume to meet production needs.

• Adapt to high temperature environment:

The slag vertical mill will generate a certain amount of heat when working, resulting in a high temperature of the dust-containing gas. The dust removal equipment adopts high-temperature resistant materials and structural design, and can operate stably in high temperature environment.

• Good cleaning effect:

The pulse jet cleaning method has a strong cleaning force and good cleaning effect, which can ensure the filtration efficiency of the filter bag, reduce the dust residue on the filter bag, and extend the service life of the filter bag.

• Compact structure:

The equipment is relatively small in size and has a reasonable structural design. It is easy to install and arrange in the slag vertical mill production line without taking up too much space.

• Stable and reliable operation:

It has good mechanical properties and stability, can operate stably for a long time, and reduce the maintenance and repair workload of the equipment.

•High degree of automation:

Equipped with advanced dust cleaning control system and monitoring device, it can realize automatic operation, improve production efficiency and reduce the labor intensity of manual operation.
