During manual cleaning, there are many operators and a large amount of labor, which is easy to fatigue then cause the risk of falling and death. Safety lighting is required in daily polymerization reactor. When cleaning polyethylene powder on the wall, combustible gas contained in the powder is volatilized from time to time, dust is elegant, and site and surrounding environment are polluted. combustible gas in daily polymerization reactor is easy to exceed the standard, and possibility of explosion and fire is very high.
When cleaning with ultra-high-pressure water, there is one operator in the reactor. Safety lighting is not required in reactor. The ultra-high pressure water gun is directly controlled by operator and cleaned polyethylene wall scale directly flows out of reactor with water.
In a humid environment with water, there is almost no possibility of fire and explosion in confined spaces.
