Description
Technical field
The utility model is related to demister technical field, more particularly to a kind of integrated form demister.
Background technology
Demister is that is, gravity, inertia force, centrifugal force, moisture film etc. are to large-size chemical using the physical method of gas-liquid separation
It is removed with desulfurizing tower droplet, i.e., the pollutant dust carried in droplet is trapped.The basic ginseng of performance design
Number is that, by the flue gas flow rate of demister, and it with the flue gas flow rate of 100% load is demister design basis to be.Demister
The performance of fog removal performance and the height of demisting efficiency have direct relation with flue gas flow rate and absorption tower demisting device designed elevation, remove
Mist efficiency high requires flue gas flow rate in certain suitable interval, also requires that mass transfer reaction area downstream meets 80 with demister absolute altitude
Droplet more than μm forms the flue gas flow rate design of freely falling body, i.e. gravity demisting.Flue gas flow rate is too low or too high, and demisting efficiency is all
Can decline, can all be unsatisfactory for outlet removal droplet criterion.
In existing flue gas desulfurization demisting technology, the overwhelming majority uses baffle type mist eliminator, is divided into plate cloth
Put or ridge-roof type arrangement, general majority is two-stage or three-level, while being provided with rinse-system.Baffle type mist eliminator is to use inertia
The physical method of power and moisture film makes gas-liquid separation, and optimum Working adapts to flue gas flow rate in 3.3~3.8m/s range intervals, fortune
In 80~150Pa, as operation pressure ＞ 150Pa, (conversion is air-flow perforation strength factor F to row pressure difference0(unit is kg to ＞ 60.5/
m0.5S)), band Water l oad increase forms reentrainment, demisting efficiency reduction.
Because the leaf angle of baffle type mist eliminator is limited by design is rinsed, inertia force is unsuitable excessive, so air-flow is worn
Hole strength factor F0The design upper limit must ＜ 6, produced kinetic energy do not play trapping and acts on to the droplet of more than 20 μm of ＜.
Baffle type mist eliminator arranges rinse-system, is pasted after being trapped to it on blade arranged at a certain distance at it
Dust (containing calcium class materials such as gypsum) is rinsed out on time, and otherwise, baffle type mist eliminator blade will be blocked.If it happens
Large area is blocked, and during operation pressure ＞ 150Pa, band Water l oad increase forms reentrainment, and meeting part or large area are collapsed when serious
Fall into.
Another flue gas desulfurization demisting technology is spiral-flow plate-type demister, due to the maximization of desulfurization tower, more using simultaneously
Arrange the combined rotational flow plate defroster (patent No.：ZL201220723758.4).Spiral-flow plate-type demister is using inertia force+centrifugation
The defogging equipment of power, centrifugal force is bigger, and gas-liquid separation efficiency is higher, and the arresting efficiency to droplet is higher.And centrifugal force size takes
Certainly in flue gas flow rate and smoke density, i.e. gas velocity be big, smoke density big, centrifugal force is just big, and gas-liquid separation efficiency is just high.Work as fortune
When row veneer pressure difference is between 250~400Pa, i.e. the ＜ F of the air-flow perforation strength factor 140(unit is kg to ＜ 200.5/m0.5S), two
To the droplet of more than 7~8 μm of ＞, general demisting efficiency is 99.9% to level rotational flow plate defroster, by rotational flow plate defroster demisting
Afterwards, below 7~8 μm of droplet ＜, dust carrying amount is general in 0.5~5mg/Nm3。
Rotational flow plate defroster also arranges rinse-system, and it is being in tangentially-arranged leaf by certain inclination angle to be pasted after being trapped to it
Piece and air-flow get rid of at a high speed after gas-liquid separation rinsed out on time to the droplet (containing dust, gypsum etc.) of bucket wall under the action of the centrifugal force,
Otherwise, rotational flow plate defroster will be blocked, and meeting part or large area are collapsed when serious.
