Product Details

Cement plants are one of the important industries that cause dust pollution, so a large number of bag filters are used in cement plants. The selection and use of filter materials are still its core technology, which plays an important role in the performance of equipment. Therefore, it is necessary to choose reasonable filter materials. The dust and smoke emitted by cement plants have different characteristics depending on the process, such as:

1. High temperature, such as the dust emitted from the tail of a rotary kiln, can reach up to 400 degrees Celsius. Therefore, it is necessary to undergo tempering and cooling before processing;

2. High humidity, such as mechanical kilns and dryers, with constantly changing temperatures and a moisture content of over 20%;

3. A bag filter with high concentration, which is matched with a vertical mill and a powder selector, can process dust containing gases with a dust concentration of 700-1600g/m3. The bag filter is a dust collection equipment in various industrial production processes and an environmentally friendly equipment for dust emission control.

4. Flame and explosion prevention, such as dust containing gases containing coal powder discharged from coal mills.

Summary: For dust with high temperature, high humidity, high concentration, and explosive properties, as well as dust with large temperature fluctuations, it is necessary to prevent bag sticking and burning;

The cement specific dust collector is designed based on the aperture of various powdery substances such as cement, fly ash, stone powder, mineral powder, chemical powder, etc. The filter element of the dust collector is designed to meet the filtration requirements of various powdery substances through the influence of large diameter and adhesion on the aperture of the filter element. It not only meets the requirements of air supply for bulk trucks and air supply for disassembled packaged products, but also ensures that there is no negative pressure in the warehouse when using powder materials. It has the advantages of small size and compact structure, with a filtration area of 24 square meters, small volume, vibration cleaning, and uses German imported filter material filter cartridges.

Characteristics of cement specific dust collector:

1. The layout of the inlet and outlet air ducts is compact, with low airflow resistance.

2. The box adopts an airtight design with good sealing performance. The inspection door uses excellent sealing materials, and during the manufacturing process, kerosene is used for leak detection, resulting in a very low air leakage rate.

3. The bag dust removal equipment in the cement plant adopts the method of replacing the bag at the top. When replacing the bag, the dust removal skeleton is extracted, and the dirty bag is put into the lower ash hopper of the box and removed from the manhole, which improves the operating conditions for bag replacement.

4. The maintenance and bag replacement can be carried out in separate rooms under normal operating conditions of the system fan and cement plant dust collector without stopping. The bag mouth of the dust removal bag adopts an elastic expansion ring, which has good sealing performance and is firm and reliable.

5. Due to the use of segmented air stop pulse spraying for dust removal in cement plants, the cleaning cycle is extended and the energy consumption for cleaning is reduced, resulting in a significant decrease in compressed air consumption.

6. The dedicated dust collector for cement plants adopts the technique of segmented air stop pulse blowing for dust cleaning, which overcomes the shortcomings of conventional pulse dust collectors and segmented back blowing dust collectors.
