Introduction to Dust Collector for Cement Plant Shaft Kiln
1、 Overview
During the production process of the vertical kiln, a large amount of dust is generated, which requires the installation of dust removal equipment for treatment. Our company has designed a bag filter for the vertical kiln dust collector, but the dust in the vertical kiln has a considerable humidity. When the external temperature is relatively low, condensation and other phenomena will occur, which will cause the air permeability of the filter bag and result in losses to the production of the enterprise. To avoid this phenomenon, insulation measures should be taken during the production of the dust collector. The filter material should be selected as polyester needle felt, and the filtration speed should be determined as 1.5m/min.
2、 Characteristics and advantages of vertical kiln dust collector in cement plant
1. This dust collector adopts the technology of segmented air stop pulse blowing for dust cleaning, which overcomes the shortcomings of conventional pulse bag dust collectors and segmented back blowing dust collectors. It has low emission concentration, low air leakage rate, low energy consumption, low steel consumption, small footprint, stable operation, and good economic benefits. Suitable for the purification of dusty gases and material recovery in metallurgy, building materials, cement, machinery, chemical, power, and light industry industries. www.hbhualan.com
2. Due to the use of segmented air stop pulse spraying for dust cleaning, the cleaning cycle is extended and the energy consumption for dust cleaning is reduced, resulting in a significant decrease in compressed air consumption. At the same time, the fatigue level of the filter bag and pulse valve is correspondingly reduced, thereby doubling the service life of the filter bag and valve plate.
3. The maintenance and bag replacement can be carried out in separate rooms without stopping the system fan and under normal operating conditions of the system. The filter bag mouth adopts an elastic expansion ring, which has good sealing performance and is firm. The filter bag keel adopts a polygonal shape, which reduces the friction between the bag and the keel, extends the life of the bag, and is easy to unload.
4. Adopting the upper bag extraction method, after extracting the skeleton during bag replacement, the dirty bag is put into the lower ash hopper of the box and removed from the manhole, which meets the operating conditions for bag replacement.
5. 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.
6. The layout of the inlet and outlet air ducts is compact, with low airflow resistance.
3、 Maintenance and upkeep standards for dust collectors in cement plant shaft kilns
（1） After three months of operation, the dust collector should undergo maintenance, which includes the following contents and requirements:
1. Check the condition of external pillars, handholes, protective plates, etc.
2. Dust accumulation in the flue and dust collector.
3. Check and adjust the baffle or cloth bag.
4. Check the tightness of the dust collector.
5. Check the mechanical ash removal device, refueling, and minor defects.
6. Check the water supply system.
（2） After one year of operation, the dust collector should undergo a second level maintenance, which includes the following contents and requirements:
1. Repair defects in brackets, handholes, and casings.
2. Leakage phenomenon of dust collector.
3. Repair or replace damaged blades, liners, flues, and regulating baffles.
4. Repair or replace the cloth bag.
5. Repair the mechanical ash removal device and replace damaged components.
6. Repair the water supply system and piping.
7. Clean up the dust accumulation in the flue and dust collector, and repair any smoke or gas leakage defects.
8. Repaint.
9. Inspect chimneys, cables, lightning protection devices, and escalators.
The vertical kiln dust collector produced by Hualan Company in the cement plant has good dust removal quality and long service life.
