Product details

The pulse dust collector in pharmaceutical factories has the advantages of high purification efficiency, large gas processing capacity, stable performance, long filter bag life, easy operation, and low maintenance workload.
Working principle of pulse dust collector in pharmaceutical factory:
When the dusty gas enters the dust collector through the inlet, it first encounters the inclined plate and baffle in the middle of the inlet and outlet, and the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down, and due to inertia, the coarse particles of dust in the gas directly flow into the ash hopper. Playing a role in pre dust collection, the airflow entering the ash hopper is then deflected upwards and captured on the outer surface of the filter bag through the filter bag equipped with a metal skeleton inside. The purified gas enters the upper clean room of the filter bag chamber and is collected at the air outlet for discharge. During the process of purifying the dusty gas through the filter bag, as time increases, more and more dust accumulates on the filter bag, increasing the resistance of the filter bag and gradually reducing the processing air volume. To work normally, the resistance must be controlled within a certain range (140-170 mm water column). Once it exceeds the range, the filter bag must be cleaned. During dust cleaning, the pulse controller sequentially triggers each control valve to open the pulse valve, and the compressed air in the air bag is sprayed from each hole of the spray pipe through the Venturi pipe to each hole in the air bag. In the corresponding filter bag, the filter bag rapidly expands instantly, causing the dust accumulated on the surface of the filter bag to fall off, The filter bag returns to its initial state. The dust falls into the ash hopper and is discharged from the machine through the ash discharge system. As a result, the dust accumulated on the filter bag is periodically pulse blown to clean the dust, allowing the purified gas to pass through normally and ensuring the operation of the dust removal system.

Characteristics of pulse dust collectors in pharmaceutical factories:
1. Pharmaceutical factoryPulse dust collectorBy adopting the technique of intermittent pulse blowing for dust cleaning in separate rooms, the shortcomings of conventional pulse dust collectors and back blowing dust collectors in separate rooms are overcome. The dust cleaning ability is strong, the dust removal efficiency is high, the emission concentration is low, the air leakage rate is small, the energy consumption is low, the steel consumption is low, the footprint is small, the operation is stable and reliable, and the economic benefits are good. Suitable for the purification of dusty gases and material recovery in metallurgy, building materials, cement, machinery, chemical, power, and light industry industries.
2. Due to the use of split chamber air stop pulse spraying for thorough cleaning, the cleaning cycle is extended and the energy consumption for 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 and reliable. 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. The pulse dust collector in the pharmaceutical factory adopts the upper bag extraction method. When changing bags, the skeleton is extracted, and the dirty bags are put into the lower ash hopper of the box and removed from the manhole, which improves 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 inlet and outlet air ducts of the pulse dust collector in the pharmaceutical factory are arranged compactly with low airflow resistance.
