Description
Technical field
The invention belongs to fume dust remover technical field, especially a kind of liquid film type multicyclone.
Background technique
Multiple Cyclone Unit belongs to one kind of mechanical collector, and dust removal mechanism is: utilizing the non-homogenous system of gaseous state, is making
Generated centrifugal force when high speed rotation, a kind of gas-solid-liquid separation equipment that dust is separated from air-flow.Due to particle
Suffered centrifugal force is far longer than gravity and inertia force, so the minimum grain size that cyclone separator can be separated economically can reach 5 μ
m.In addition, cyclone separator structure is fairly simple, operates, is easy to maintain, performance is stablized, and not by the concentration of dusty gas, temperature
The limitation such as transitivity is spent, and cost is lower, so being widely used in petroleum, chemical industry, coal, electric power, environmental protection and metallurgy etc.
In industrial production.
Currently, generalling use multiple minor diameter Whirlwind cyclones parallel processing side to improve the separating effect of cyclone separator
Formula, that is, multicyclone.Although multicyclone device in parallel has 80~85% dedusting to 3 μm of particle
Efficiency, but it still falls within middle effect deduster.
In Multiple Cyclone Unit in use, being easy to bounce because wall surface is coarse to whirlwind after solid particle arrival wall surface
Center circulating-area, influences efficiency of dust collection, additionally, there may be that air balance is poor, inclined suction phenomenon is serious and Whirlwind cyclone serious wear
Logical disadvantage.
Currently, there are many corrective measures for logical disadvantage.For example, the cyclone dust of quantity-adjustable
CN202263657U ensures that the air-flow in return air chamber is uniform by volume adjusting apparatus, is not in inclined suction phenomenon.Upstriker
Eddy flow water dust scrubber (CN106492565A) adds liquid film overflow launder in the upper end of vertical pipeline, the overflow in liquid film overflow launder
The moisture film of water uniformly distributed one layer very thin of continuous downward Uniform Flow on the inner wall circumference of vertical pipeline, but can leak out.Whirlwind
Settling tank is arranged in water dust scrubber CN106334401A, and form flow around type structure purification sewage by setting partition is made with recycling
With.Wet process multicyclone CN105750100A improves separator by " the liquid film absorption " on the cylinder wall in inlet chamber
Separative efficiency, also cut inflow entrance, cyclone cylinder of unique design etc. by double, improve the effect of separation.Cyclone water-film
Deduster CN204395710U and CN204395711U, vertical vortex water-film dust remover CN2774640 will introduce water in Whirlwind cyclone
Film, improves the efficiency of dust collection of Multiple Cyclone Unit, but both for single Whirlwind cyclone, and be all tangential entry type into
Gas mode.
