Stainless Steel Insulated Gas Box Pulse Bag Dust Collector

The stainless steel insulated gas box pulse bag dust collector is a one-on-one dust removal equipment designed for high humidity, corrosive or low temperature easily condensing dust scenarios. It integrates the three core characteristics of stainless steel performance stability, insulation and anti condensation, and gas box compartment dust cleaning. It is widely used in industries such as chemical, pharmaceutical, food processing, metallurgy, etc. It can handle corrosive or high humidity gases with dust concentration ≤ 2000g/m ³ and temperature -10 ℃ -200 ℃. The filtration efficiency of dust with particle size above 0.3 μ m exceeds 90%. It is a key equipment for achieving dust emission standards and stable equipment operation under special working conditions.

From the perspective of structural design, the equipment has undergone two major core upgrades on the basis of traditional gas box pulse bag dust collectors, while retaining the advantages of compartment cleaning: material upgrades. The core components such as the box body, ash hopper, and filter bag frame are all made of 304 or 316L stainless steel. 304 stainless steel is suitable for general corrosion scenarios, while 316L stainless steel is designed for strong corrosive environments (such as chlorine containing and acid containing exhaust gases), which can effectively resist the corrosion of gases and dust, extend the service life of the equipment to 8-12 years, far exceeding ordinary carbon steel dust collectors; Upgrade insulation by wrapping 50-100mm thick rock wool or polyurethane insulation layer on the outside of the box and ash hopper, and then covering it with stainless steel protective plate. This can control the temperature fluctuation inside the equipment within ± 5 ℃, prevent gas condensation in low-temperature environments, and prevent dust from adhering to the filter bag or blocking the ash hopper. In addition, the core structure still retains the design of air box compartments, usually divided into 4-10 independent air boxes, each equipped with independent inlet and exhaust valves and pulse cleaning components. The filter bags are made of special materials with stable performance and temperature resistance, such as PTFE filter bags for handling corrosive dust, waterproof (based on actual reports) and oil resistant (based on actual reports) coated filter bags for handling high humidity dust. Stainless steel star shaped discharge valves and arch breaking devices are installed at the bottom of the ash hopper to confirm smooth dust discharge.

Its working principle is based on the dust cleaning of the gas box compartment, combined with insulation and performance stability protection: dusty gases containing corrosiveness or high humidity enter through the air inlet and are evenly distributed to each gas box through the air flow distribution device. The insulation layer maintains the temperature stability inside the box and avoids condensation; Dust is trapped on the outer surface of the filter bag, and the purified gas enters the clean air chamber through the filter bag and is discharged through the air outlet; When the resistance of a certain gas box rises to the set value (1500-1800Pa), the system closes the inlet and exhaust valves of the gas box to take it offline, and the pulse valve starts to spray and clean the dust. The stainless steel material prevents gas corrosion of the equipment during the dust cleaning process; Dust falls into the insulation ash hopper, the arch breaking device avoids dust bridging, and the star shaped discharge valve discharges the dust without condensation or corrosion risk throughout the process.
