The working principle of the explosion-proof air shower room can be summarized as follows: high-speed clean air flow circulation for dust removal + full-loop explosion-proof electrical and anti-static design + double-door interlocked air lock isolation. It simultaneously achieves personnel purification and inherent safety in flammable and explosive environments.
\n1. Basic purification principle (the same as ordinary air shower room)
\nInduction and interlock: When personnel enter the air shower room, the explosion-proof infrared sensor detects the position, and the dual-door electronic interlock is activated. The two doors cannot be opened simultaneously, forming an air lock isolation.
\nAir circulation: The explosion-proof centrifugal fan sucks in the indoor air, passing through G4 primary filter (intercepting particles larger than 5 \u03bcm) \u2192 static pressure box for pressure stabilization \u2192 H13\/H14 high-efficiency filters (filtering particles of 0.3 \u03bcm with an efficiency of \u2265 99.97%).
\nHigh-speed blowing: Clean air is blown through the multi-angle adjustable nozzles on both sides and the top of the box at a speed of 25\u201335 m\/s, forming a 360\u00b0 no-corner blowing, removing dust, fibers, and microorganisms from the surface of clothing.
\nReturn air filtration: The contaminated air flows back through the bottom return grille and enters the primary \/ high-efficiency filters for further purification, preventing pollution from leaking out.
\nEnd unlocking: The blowing and showering time (usually 10\u201330 seconds) ends, the fan stops, the rear door unlocks, and personnel enter the clean area.
\n2. Explosion-proof safety principle (core difference)
\nBased on the ordinary air shower room, all electrical and structural components are designed in accordance with the explosion-proof standards of GB 3836, eliminating sparks, static electricity, and high-temperature sources.
\n1) Explosion-proof electrical configuration (Ex d IIB T4 level)
\nExplosion-proof fan: Explosion-proof motor, without spark structure, the impeller and the casing are protected from spark contact.
\nExplosion-proof control: Explosion-proof PLC, explosion-proof switches, explosion-proof emergency stop buttons, explosion-proof lighting (fluorescent lamps \/ LED).
\nExplosion-proof sensors: Explosion-proof infrared sensors, explosion-proof electromagnetic locks, explosion-proof junction boxes \/ wiring boxes.
\n2) Anti-static and spark-free structure
\nBox material: 304\/316 stainless steel or anti-static cold-rolled steel plate, overall grounding to eliminate static charge accumulation.
\nNozzle \/ fan blades: Stainless steel or aluminum alloy to avoid sparks caused by friction and impact.
\nSealing and wiring: Explosion-proof sealing rubber rings, explosion-proof cable sealing joints, lines passing through explosion-proof steel pipes to prevent flammable gases from entering the electrical cavity.
\n3) Safety interlock and emergency
\nDoor interlock: Dual electronic + mechanical double interlock for the two doors. The interlock is forced closed during the showering to prevent the leakage of flammable gases.
\nStatus indication: Explosion-proof indicator lights (green \/ red) display the standby \/ working status.
\nEmergency stop protection: Multiple explosion-proof emergency stop buttons inside and outside the room, one-click power-off unlocking to ensure emergency evacuation.
\n3. Work process (one-step completion)
\nPersonnel enter \u2192 Front door closed \u2192 Infrared sensor triggered \u2192 Dual-door interlock locking.
\nExplosion-proof fan starts \u2192 Air passes through primary + high-efficiency filters \u2192 Nozzle high-speed blowing for dust removal.
\nContaminated air returns for filtration \u2192 Circulation purification.
\nTime ends \u2192 Fan stops \u2192 Rear door unlocks \u2192 Personnel enter the explosion-proof clean area.
\n4. Application scenarios
\nSuitable for clean environments with flammable gases, combustible dust, and explosion hazards:
\nLithium battery manufacturing (aluminum powder, electrolyte vapor)
\nChemical \/ pharmaceutical (organic solvents, combustible dust)
\nSpraying \/ ink workshop (paint mist, solvent vapor)
\nMilitary \/ aerospace (propellant, flammable powder)<\/p>","protected":false},"excerpt":{"rendered":"
