When using the pulse bag dust collector , pay attention to it. If there is a lot of moisture in the flue gas and the smoke is highly hygroscopic with dust, the filter bag will block the filter material. Measures must ensure that the moisture in the air does not condense, the dust removal effect will be good.
The pulse bag dust collector has a strong dust removal effect. It should be noted that if the dust collector is used in a cold area, water vapor will condense and affect the blowing effect of the dust collector. Do not place the dust collector outdoors.
由灰斗、上箱体、中箱体、下箱体等部分组成，上、中、下箱体为分室结构。 The pulse bag filter is composed of ash hopper, upper box, middle box, lower box and other parts. The upper, middle and lower boxes are divided into compartments. During work, the dust-containing gas enters the ash hopper from the air inlet, and the coarse dust particles directly fall into the bottom of the ash hopper. The fine dust particles enter the middle and lower boxes with the airflow turning upward, and the dust is accumulated on the outer surface of the filter bag. Gas enters upper box to clean gas collecting pipe - The exhaust duct is exhausted to the atmosphere by the exhaust fan. The ash cleaning process is to first cut off the air outlet air duct of the chamber, so that the bag of the chamber is in a state without air flow. ( Air separation and dust removal ) . Then open the pulse valve and use compressed air for pulsed ash cleaning. The closing time of the shut-off valve is sufficient to ensure that the dust peeled from the filter bag after sedimentation is settled in the ash hopper, which prevents the dust from collecting with the air flow after leaving the filter bag surface To the surface of the adjacent filter bag, the filter bag is cleaned, and the exhaust valve, pulse valve and ash discharge valve are automatically controlled by a programmable controller.
Features of pulse bag filter:
1.Using the air separation pulse spray ash cleaning technology to overcome the shortcomings of the conventional pulse dust collector and the room reverse blow dust collector, with strong ash cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate, low energy consumption, and steel Less consumption, less floor space, stable and reliable operation, and good economic benefits. Suitable for metallurgical, building materials, cement, machinery, chemical, power, light industry industries, dust-containing gas purification and material recovery.
2. As the ash cleaning pulse is used to separate the air from the chamber, the ash can be completely cleaned in one shot, so the ash cleaning cycle is extended, the ash cleaning energy consumption is reduced, and the compressed air consumption can be greatly reduced. At the same time, the fatigue of the filter bag and the pulse valve is correspondingly reduced, thereby doubling the life of the filter bag and the valve plate.
3, bag replacement can be carried out in non-stop system fan, the system under normal operating conditions. The mouth of the filter bag 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, prolongs the life of the bag, and facilitates the unloading of the bag.
4. The upper bag extraction method is adopted. After the skeleton is pulled out during bag replacement, the dirty bag is put into the ash bucket at the lower part of the box and taken out from the manhole, which improves the bag changing operation conditions.
5. The box body adopts air-tight design, good sealing performance, excellent sealing materials for inspection doors, kerosene leak detection during the production process, and the air leakage rate is very low.
6. The inlet and outlet air ducts are compactly arranged and the airflow resistance is small.
Application of pulse bag filter:
The pulse bag filter adopts the off-line pulse cleaning technology, which overcomes the shortcomings of reverse blow cleaning and general pulse cleaning. It has strong cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate, low energy consumption, and takes up land. Small area, reliable and stable operation. This series of dust collectors are particularly suitable for the following occasions: dust removal in calcium carbide furnaces, dust removal in various electric furnaces in ferroalloy plants; flue gas purification in steel plants; dust removal in coal-fired boilers and small boilers in power plants; dust removal in refuse incinerators; high-temperature flue gas dust removal in smelters; aluminum plants Flue gas purification; dust removal from rotary kiln tail and kiln head of cement plant; dust removal from carbon black plant exhaust. Its application field is characterized by high temperature and large smoke volume.
