Select explosion-proof air shower cabinets, the core is to first determine the explosion-proof level \u2192 then match the purification and size \u2192 finally check the material, electrical and certification. Five steps can lock in the compatible model, avoiding both safety and purification risks.
\n1. First, clearly define the hazardous environment (the explosion-proof level is the lifeline)
\n1) Hazard zone classification (GB 3836\/GB 50058)
\nZone 0: Continuous presence of flammable gas (rarely used, requires Ex ia intrinsically safe type)
\nZone 1: May occur during normal operation (mainstream: Ex d IIB T4 flameproof type)
\nZone 2: Only briefly present during abnormal conditions (optional: Ex d IIB T4 or Ex ec enhanced safety type)
\n2) Temperature group (T4 is the most commonly used)
\nT4 (\u2264135\u2103): Lithium batteries, chemicals, pharmaceuticals (suitable for most solvents \/ dust)
\nT6 (\u226485\u2103): Highly flammable media (such as ether, ethylene oxide)
\n3) Typical industry configuration reference
\nLithium battery workshop (aluminum powder \/ electrolyte vapor): Ex d IIB T4, 304 stainless steel, anti-static
\nChemical \/ pharmaceutical (organic solvents): Ex d IIB T4, 316 stainless steel, corrosion-resistant
\nSpraying \/ ink (paint mist \/ solvent): Ex d IIB T4, anti-static nozzle, spark-free fan
\n2. Match purification level and air shower performance
\n1) Cleanliness level corresponding configuration
\nISO 5\u20136 grades (hundred-level \/ thousand-level): H14 high efficiency, wind speed \u2265 28m\/s, air shower 25\u201330s, all 304\/316 stainless steel
\nISO 7\u20138 grades (ten-thousand-level \/ hundred-thousand-level): H13 high efficiency, wind speed \u2265 25m\/s, air shower 15\u201320s, 304 stainless steel
\n2) Core performance hard indicators (must be met)
\nNozzle wind speed: \u2265 25m\/s (dust removal rate \u2265 95%), prefer 28\u201330m\/s
\nInternal average wind speed: \u226518m\/s, uniformity deviation \u22645m\/s (anti-dead corners)
\nFilter efficiency\uff1a H13 (\u2265 99.9%@0.3\u03bcm) or H14 (\u2265 99.97%@0.3\u03bcm)
\n3. Size and passage method (compatible with the number of people and space)
\n1) Conventional size (width \u00d7 depth \u00d7 height\uff0c mm)
\nSingle person single air shower\uff1a 800\u00d7800\u00d72000 (1 person \/ time\uff0c small workshop)
\nDouble person double air shower\uff1a 1200\u00d7800\u00d72000 (2 people \/ time\uff0c medium workshop)
\nMany people \/ passage\uff1a 1500\u00d7800\u00d72000 or above (3\u20136 people \/ time\uff0c large workshop)
\n2) Door body and layout
\nDouble door interlock\uff1a electronic + mechanical dual interlock (door closes during air shower\uff0c prevents gas leakage)
\nDoor opening direction\uff1a single opening \/ double opening \/ sliding door (suitable for on-site movement)
\nCorner type\uff1a saves space (suitable for L-shaped corridors)
\n4. Material and explosion-proof electrical (safety and durability dual guarantee)
\n1) Box material (explosion-proof + anti-static + corrosion-resistant)
\n304 stainless steel\uff1a general use\uff0c anti-static\uff0c easy to clean (lithium batteries \/ pharmaceuticals preferred)
\n316 stainless steel\uff1a resistant to acid and alkali corrosion (chemicals \/ humid environment)
\nAnti-static cold-rolled steel plate\uff1a low cost\uff0c requires overall grounding (general explosion-proof area)
\n2) Explosion-proof electrical list (must be included)
\nExplosion-proof fan (flameproof motor\uff0c no spark impeller)
\nExplosion-proof PLC + explosion-proof switch + explosion-proof emergency stop button
\nExplosion-proof infrared sensor + explosion-proof electromagnetic lock
\nExplosion-proof lighting (LED \/ fluorescent lamp) + explosion-proof junction box \/ wiring box
\nAnti-static nozzle (stainless steel \/ aluminum alloy\uff0c anti-friction spark)
\n5. Certification and manufacturer (key to avoiding pitfalls)
\n1) Required certifications Explosion-proof Certification: GB 3836 (Classified Explosion-proof), GB 12476 (Dust Explosion-proof), with explosion-proof certificate
\nCleanliness Certification: GB 50073, ISO 14644, supports PAO leak detection
\nMaterial Certification: Stainless steel material report, anti-static grounding test report
\n2) Manufacturer Screening
\nHas explosion-proof equipment production qualification, not an ordinary air shower room modification
\nProvides explosion-proof drawings + electrical schematic diagram + factory test report
\nCan conduct on-site explosion-proof grounding test + air velocity uniformity test
\nSix. Selection Decision Checklist (Directly check corresponding items)
\nDangerous Area: \u25a1Zone1 (Ex d IIB T4) \u25a1Zone2 (Ex d IIB T4)
\nCleanliness Level: \u25a1ISO5\u20136 (H14\/28m\/s) \u25a1ISO7\u20138 (H13\/25m\/s)
\nSize: \u25a1Single person 800\u00d7800 \u25a1Double person 1200\u00d7800 \u25a1Customized for multiple people
\nMaterial: \u25a1304 Stainless Steel \u25a1316 Stainless Steel \u25a1Anti-static Steel Plate
\nElectrical: \u25a1Full explosion-proof \u25a1Anti-static Grounding \u25a1Double-door Interlock
\nCertification: \u25a1Explosion-proof Certificate \u25a1Cleanliness Inspection Report \u25a1Material Certification
\nSeven. Common Pit Avoidance Reminders
\n\u274c Convert ordinary air shower room to explosion-proof: Electrical not explosion-proof, poor grounding, explosion risk is extremely high
\n\u274c Only focus on price: Ignore explosion-proof grade, air velocity uniformity, material thickness, and later safety \/ purification will both fail
\n\u274c Ignore dust explosion-proof: Lithium battery \/ aluminum powder workshop needs to meet both gas + dust explosion-proof (Ex tD)<\/p>","protected":false},"excerpt":{"rendered":"
