Separation pressure vessels are mainly pressure vessels used to complete the fluid pressure balance buffering and gas purification separation of the medium, such as separators, filters, oil collectors, buffers, scrubbers, absorption towers, copper washing towers, drying towers, and stripping towers. Tower, sub-cylinder, deaerator, etc. The separation pressure vessel is a sealed container with high safety requirements, so its maintenance is also crucial. Let's talk about the matters that should be paid attention to during the maintenance of the separation pressure vessel.
Pay attention to ventilation and supervision
before entering the drum or container. It is necessary to open all the inlet holes on the drum, the container and the hand holes on the header to allow air convection for a certain period of time to fully ventilate. When entering the drum or container for inspection, someone must be supervised outside the equipment. Ventilation must also be carried out before entering the flue or combustion chamber for inspection.
Pay attention to the safety of electricity use
When inspecting the drum and humid flue and using electric lighting for lighting, the lighting voltage should not exceed that in a relatively dry flue and if appropriate safety measures are in place, no higher than When the lighting voltage enters the container for inspection, a low-voltage explosion-proof lamp with a voltage not exceeding or should be used. When the power supply voltage of inspection instruments and repair tools exceeds the limit, well-insulated soft wires and reliable grounding wires must be used. It is strictly prohibited to use open flame lighting in boilers and containers.
It is prohibited to disassemble and assemble connecting parts under pressure
When inspecting boilers and separate pressure vessels, if it is necessary to remove or tighten the fasteners of pressure-bearing parts, all pressure must be released before proceeding and no further installation can be carried out. Remove or tighten bolts or other fasteners when there is pressure inside to prevent accidents.
The above are the safety precautions in the maintenance of separated pressure vessels compiled by the editor. In addition, when choosing separated pressure vessels, you should choose manufacturers with formal production procedures. Their products are of better quality and safer to use. I hope my article will be useful to you. Helps.
