Explosion-proof air shower filter replacement procedure (primary efficiency + secondary efficiency, including explosion-proof safety regulations)
\nKey points: Full power-off explosion-proof operation, anti-static, explosion-proof dust environment must be free of dust flying, conduct leak detection and wind speed measurement after replacement. Proceed step by step according to the standard procedure and follow it directly.
\n1. Preparations before replacement (explosion-proof safety first, must be done)
\nStop the machine and cut off the power supply
\nTurn off the main power supply, hang a sign and lock (LOTO), do not touch and disassemble with power on; Do not open the cover in dust \/ flammable and explosive areas with power on.
\nPersonal protection
\nWear anti-static clothing, gloves, mask, use dust-free tools, do not use iron tools to strike or rub to generate sparks.
\nClear the site
\nEmpty the internal debris of the air shower room, clean the return air duct and the surrounding dust of the nozzle, reduce dust flying.
\nComponent verification
\nPrimary efficiency: G4 plate-type filter
\nSecondary efficiency: H13\/H14 with or without partitioned \/ without partitioned high-efficiency filter (size consistent with the original factory)
\nDo not use ordinary high-efficiency filters from non-explosion-proof areas as substitutes, the sealing rubber strip must be intact.
\n2. Replacement of primary efficiency filter (the simplest, once every 3-6 months)
\nOpen the inspection panel of the air shower room return air inlet (lower part \/ side of the box).
\nRemove the old primary efficiency filter, wrap it in a sealed bag and take it out to avoid dust scattering.
\nClean the accumulated dust in the filter frame.
\nPlace the new primary efficiency filter flatly, with the arrow pointing towards the airflow direction (towards the fan side).
\nPress the clamps tightly, seal it tightly, and reinstall it on the inspection panel.
\nExplosion-proof workshop with lithium batteries, aluminum powder, dust: Replace once every 2-3 months, do not use repeatedly after long-term water washing.
\n3. Replacement of secondary efficiency filter (critical, once every 6-12 months, replace immediately if the pressure difference exceeds the limit)
\nStep 1: Open the inspection opening of the top static pressure box
\nAfter cutting off the power supply, open the top inspection cover of the air shower room (all explosion-proof screws evenly loosen, do not use violent knocking).
\nDo not use metal tools to forcefully collide the box body in an explosion-proof environment to prevent sparks.
\nStep 2: Remove the old secondary efficiency filter
\nLoosen the pressure strip \/ pressure plate, gently remove the old secondary efficiency filter.
\nThe old secondary efficiency filter is sealed with a plastic bag and taken out, do not shake and cause dust flying in a dust \/ flammable and explosive environment.
\nClean the dust, oil stains, and residual glue inside the static pressure box.
\nStep 3: Install the new secondary efficiency filter (focus on sealing)
\nCheck that the edge frame and sealing strip of the filter are undamaged and undented.
\nThe air flow direction arrow of the filter is facing down (towards the nozzle), align and center it.
\nEvenly tighten the screws around the pressure strip, tighten diagonally in turns, ensure no air leakage in all sides, do not allow unilateral pressure tightening.
\nExplosion-proof area: The screws must be tightened to prevent vibration and loosening from friction and static electricity.
\nStep 4: Restore the cover plate
\nInstall the top inspection plate, evenly lock the explosion-proof screws, ensure the sealing pad is intact, and ensure the explosion-proof cavity is sealed.
\n4. After replacement, debugging and testing (explosion-proof + clean double acceptance)
\nPower on for trial operation, turn on the fan, check for air leakage and abnormal sounds.
\nMeasure the blowing shower wind speed: standard 25\u201330m\/s, if the wind speed is insufficient, check the secondary efficiency seal.
\nPAO leak detection (must be done in a clean workshop): Leak detection of the secondary efficiency filter and frame, no leakage.
\nCheck the interlock of the double doors, explosion-proof electrical equipment, and normal grounding.
\nMake a replacement record: date, model, pressure difference, wind speed, test results.
\n5. Special prohibitions in explosion-proof environment (very important)
\nDo not replace the filter with power on, do not open the static pressure box with power on.
\nDust explosion (lithium batteries, aluminum powder): During the replacement, dust must not be scattered, the old filter sealing tape must be taken out of the workshop for processing.
\nDo not use damaged, aged sealing strips, non-original factory size high-efficiency filters, which will cause air leakage, pollution + static electricity hazards.
\nAfter replacement, confirm that the box body is grounded normally, no explosion-proof static electricity problems.
\n6. Replacement cycle reference
\nPrimary efficiency filter: ordinary environment 3\u20136 months; flammable and explosive dust environment 2\u20133 months
\nSecondary efficiency filter: ordinary environment 6\u201312 months; dust heavy \/ high cleanliness environment 4\u20136 months If the pressure difference gauge exceeds 200 Pa or the wind speed significantly decreases \u2192 Immediately replace it<\/p>","protected":false},"excerpt":{"rendered":"
