Description
Technical field
The present invention relates to turbulent flow coalescence electricity mist cleaner, belongs to environmental technology field.
Background technology
What rapids rushed that coalescence utilizes is foamed cleaning technology, except that it creatively make use of hydromechanical correlation
Theory, using brand-new, more simple and reliable method more stable effective froth bed is produced.Its operation principle is：
1st, using foamed cleaning technology, using foam surface layer greatly, gas-liquid interface renewal speed be exceedingly fast the characteristics of, enter
The efficient mass-and heat-transfer process of row.
2nd, in biphase gas and liquid flow kinety system, the flow pattern of fluid depends on the relative mass flow rates of gas-liquid two-phase, certain
Under the conditions of can form stable froth bed.
3rd, froth bed is that gas-liquid two-phase interacts to be formed in intersection, and the position of its interface depends on gas-liquid two-phase
Momentum balance relation.Under conditions of momentum balance, interface will stabilise at a position, and work as the generation of gas-liquid relative momentum
During change, the fluid flow direction movement that interface can increase to momentum, until reaching new balance.
The height of wet purification device efficiency depends on the consumption of its energy, because turbulent flow coalescence scrubber is in running
In both make use of the energy of air-flow, also dexterously make use of the energy of liquid stream.Water mist dust-removing is that one kind is extensive in produce reality
Using and simple and practical dedusting method, by humid control of the spraying to material, play important to reducing dust yield

With the collision probability of powder dust particle, by water smoke particle diameter in corona field action lower band electric charge, under electrostatic force, strengthen dust
Mutually collide with droplet, reach the purpose of trapping dust.
Charged water spray dedusting technology is that the water of atomization is charged, is combined with dust by effects such as electrostatic attractions, makes dust
Grain cohesion becomes big and removes.Motion in cleaner unit is dynamic for dilute gas-solid two-phase flow, and in operation stress mainly has powder dust particle
Electrostatic force, viscous resistance and particle weight power.Charged water spray dedusting is the combination of electrostatic precipitation and wet dust removal, overcomes spraying to remove
The dirt problem low to fine dust capture rate.
The purpose of water fog charge is that the droplet for forming spraying obtains higher electric charge, increases water smoke and dust collider
Meeting, so as to improve arresting efficiency of the water smoke to dust.Water fog charge mode is divided into corona charging and injection charged two in this equipment
Kind.
Corona electricity makes inductance loop (i.e. positive plate) using tinsel, and plus high-pressure electricity, releases inductance loop on inductance loop
Electrostatic discharge lotus, nozzle is located at inductance loop center, when water smoke passes through inductance loop, under electric field action, is allowed to take and sensing
The electric charge (negative electricity) of ring opposite polarity.
The method is a kind of effectively charged mode, makes water smoke obtain higher electric charge (water smoke charge-mass ratio).Water fog charge
Afterwards, increase collision, diffusion, the retention probability with powder dust particle, improve the dust removing effects that fine dirt is particularly to dust.
