Piping design, due to the unreasonable design and operation of the explosion-proof Industrial vacuum cleaner of the whole machine, smoke and dust gather together and explode.

(1) The pipeline should be made of fish-removing steel metal materials to avoid fish accumulation, while appropriately increasing the fish in the pipeline, so that the maximum concentration of air dust in the pipeline during normal operation and failure does not exceed 50% of the lower explosion limit.

(2) In order to prevent the accumulation of dust in the pipeline, use round pipes for combustible dust and combustible dust to minimize the length of the horizontal pipeline and reduce the number of elbows. Do not install ends and bags on the pipeline to avoid dust accumulation. There is a clean mouth at 6 meters. The pipe interface is fastened with metal components, and is a transitional connection with the same area as the horizontal connection of the pipe. Whole machine explosion-proof industrial vacuum cleaner.

(3) Prevent the further development of the explosion immediately after the local pipeline explosion, prevent the explosion wave caused by the explosion from leaking, causing dust, causing secondary explosions, pipeline laying overhead, underground and semi-underground buildings hidden and arranged in underground buildings Every 6 meters in length of the pipeline, branch pipelines gather 1 meter upstream of the centralized exhaust pipeline at the interface of the centralized exhaust pipeline. Set the exhaust pressure area and the open pressure to meet the requirements of the radial control exhaust pressure port, each dust removal branch and An automatic explosion-proof valve is set at the connection of the main air return pipe. If the control exhaust pressure port is set in the site building, an exhaust pipe with a length of not more than 6 meters is opened to the outdoors.

(4) The connection system shall not be connected by pipes. In order to prevent sputtering into the pipeline, the inlet of the dust hood cannot face the sputtering generated during the process. Piping and fittings should adopt pressure relief design. Industrial explosion-proof vacuum cleaner,

Emergency fire protection measures:

The accident was caused by improper selection of fire fighting equipment.

Fire extinguishing agents should be used to extinguish the smoke and dust, and ordinary fire extinguishers are strictly prohibited.
