Lithium Battery Industry Stainless Steel Filter

Stainless Steel Filters for the Lithium Battery Industry

[1] The specific applications of stainless steel dust collectors are primarily determined by the properties of stainless steel plates. The selection of stainless steel dust collector models follows the same method as that for carbon steel pulse dust collectors, with considerations such as site conditions, processing air volume, and filtration area to choose the appropriate dust collector. Working Principle of Stainless Steel Dust Collectors: Stainless steel dust collectors operate by using compressed air pulses to remove dust attached to the filtration media (bags or cartridges). Depending on the size of the dust collector, there may be several sets of pulse valves controlled by a pulse controller or PLC. Each set of pulse valves is activated in turn to clean the dust from the corresponding section of bags or cartridges while the others continue to operate normally. After a certain interval, the next set of pulse valves opens to clean the next section. The dust collector consists of a hopper, upper chamber, middle chamber, and lower chamber, with the upper, middle, and lower chambers designed as separate compartments. During operation, dust-laden gas enters the hopper through the inlet duct. Coarse dust particles fall directly to the bottom of the hopper, while fine dust particles follow the airflow upward into the middle and lower chambers, where dust accumulates on the outer surface of the filter bags. The filtered gas enters the upper chamber and proceeds to the clean air collection pipe and exhaust duct, eventually being discharged into the atmosphere by the exhaust fan. The cleaning process involves first cutting off the clean air outlet duct of the compartment, leaving the bags in that compartment without airflow (compartmentalized air-off cleaning). Then, the pulse valve is opened to inject compressed air for pulse-jet cleaning. The closing time of the shut-off valve is sufficient to ensure that the dust dislodged from the filter bags settles into the hopper, preventing re-entrainment onto adjacent filter bags. This ensures thorough cleaning of the filter bags. The entire process, including the exhaust valve, pulse valve, and discharge valve, is automatically controlled by a programmable controller. Dust-laden gas enters through the inlet and passes through the hopper, where some large dust particles are separated by inertia and gravity, falling directly to the bottom of the hopper. The gas then enters the filter bag area in the middle chamber. As the gas passes through the filter bags, dust is trapped on the outer surface, and the purified gas enters the upper chamber through the bag openings before being discharged via the outlet.

Introduction to Stainless Steel Dust Collectors

Stainless steel dust collectors are primarily selected based on the properties of stainless steel plates. The model selection process is similar to that for carbon steel pulse dust collectors, with considerations for site conditions, processing air volume, and filtration area to choose the suitable dust collector.

Working Principle of Stainless Steel Dust Collectors

Working Principle of Stainless Steel Dust Collectors
Stainless steel dust collectors remove dust from the filtration media (bags or cartridges) by pulsing compressed air. Depending on the size, there may be multiple sets of pulse valves controlled by a pulse controller or PLC. Each set cleans its designated section of bags or cartridges in sequence while others operate normally. The dust collector comprises a hopper, upper, middle, and lower chambers, with the chambers designed as separate compartments. During operation, dust-laden gas enters the hopper via the inlet duct. Coarse particles fall to the hopper bottom, while fine particles follow the airflow into the middle and lower chambers, accumulating on the filter bags' outer surface. Filtered gas enters the upper chamber and is discharged through the clean air collection pipe and exhaust duct. The cleaning process starts by isolating the compartment's clean air outlet, stopping airflow to the bags (compartmentalized air-off cleaning). Pulse valves then inject compressed air for cleaning. The shut-off valve's closing time ensures dislodged dust settles into the hopper, preventing re-attachment to adjacent bags. This thorough cleaning is automated via a programmable controller for valves and discharge mechanisms. Dust-laden gas enters through the inlet, with large particles separated in the hopper by inertia and gravity. The gas then passes through the filter bags in the middle chamber, where dust is captured externally, and purified gas exits through the upper chamber outlet.

Technical Features of Stainless Steel Dust Collectors

Advantages of Stainless Steel Dust Collectors

1. Utilizes compartmentalized air-off pulse-jet cleaning technology, overcoming limitations of conventional pulse and reverse-air dust collectors. Offers strong cleaning capability, high dust removal efficiency, low emission concentration, minimal air leakage, reduced energy and steel consumption, compact footprint, stable operation, and good economic benefits. Suitable for purifying dust-laden gases and material recovery in metallurgy, building materials, cement, machinery, chemicals, power, and light industries.

2. Compartmentalized air-off pulse-jet cleaning achieves thorough cleaning in a single pulse, extending cleaning cycles, reducing energy consumption, and significantly lowering compressed air usage. This also decreases fatigue on filter bags and pulse valves, doubling their service life.

3. Maintenance and bag replacement can be performed compartment by compartment without stopping the system fan, ensuring continuous operation. The bag opening uses an elastic expansion ring for excellent sealing and reliability. The multi-angled bag cage reduces friction, prolonging bag life and facilitating easy removal.

4. Employs top bag removal; during replacement, the skeleton is extracted, and used bags are dropped into the lower hopper for retrieval via the access door, improving operational conditions.

5. Features an airtight design with high sealing integrity. Inspection doors use premium sealing materials, and leakage testing with kerosene during manufacturing ensures very low air leakage rates.

6. Compact inlet and outlet duct design minimizes airflow resistance.

Applications of Stainless Steel Dust Collectors

Stainless steel offers excellent corrosion resistance, formability, compatibility, and toughness across a wide temperature range. It is widely used in grain and oil industries, heavy and light industries, consumer goods, and architectural decoration, particularly suited for sectors such as metallurgy, chemicals, ceramics, cement, pharmaceuticals, and food processing.
