Stretch into the housing 11 and be connected with nozzle component, the nozzle component includes multiple nozzles 22 radially distributed, institute
Nozzle component is stated towards nozzle guard 23 is provided with the housing 11 of the side of air inlet 13, nozzle guard 23 can use angle
Steel.Spray control device is installed, the spray control device includes being arranged on the shower 21 on the shower 21
Spraying electromagnetic valve 24, be provided with the dedusting chamber 12 it is multiple towards the nozzle component and the baffle plate 3 for arrangement of falling successively,
The baffle plate 3 includes the body of baffle plate 3 being vertically arranged, and the top of the body of baffle plate 3 is vertically installed with towards the air inlet
The anti-outflow flanging of 13 extensions, the lower edge of two baffle plates 3 farthest from the air inlet 13 is intended to be less than the air inlet
13 lower edge.
In the present embodiment, the installation site and quantity of nozzle component：Flue gas need to first be sprayed when entering inertial dust separator
Pouring is handled, and dust can be made to be combined with water and improve its settling efficiency, specific nozzle component is arranged at inertial dust separator smoke inlet,
And provided with protection devices such as angle steel；
In the present embodiment, the specific required quantity of nozzle 22 is then set according to air quantity and spray head parameter, and nozzle 22 exists
The anglec of rotation of nozzle 22 can be changed during setting, make its effect for not only acting as humidification gas also have cleaning to close on the double of baffle plate 3
Recast is used；
In the present embodiment, flue gas can change the flow trace of dust, be dropped by Action of Gravity Field when spraying at baffle plate 3
Into ash bucket, efficiency of dust collection is improved, the installation number of baffle plate 3 typically sets 5-10, set with specific reference to air force, air quantity
Bigger, the number of baffle plate 3 is also increased as；
The installation site of baffle plate 3 and shape：First of baffle plate 3 (thickness of slab 10mm) is set at the rear side 0.2-0.3m of nozzle 22,
Direct surrounding is welded on the housing 11 of inertial dust separator (shape is designed according to inertial dust separator inner shape).The second to four
Road baffle plate 3 be then arranged between the rear side of first baffle plate 3, baffle plate 3 be spaced in 0.3-0.5m or so (specific interval according to air quantity and
The size of inertial dust separator is determined), baffle plate 3 is bending tabular, can effectively intercept because air current flow direction changes and caused by
Grain beyond the region of objective existence stream, the size of top fold is in 0.05m or so, and the upper horizontal position of rear side baffle 3 is the horizontal centre of front side baffle plate 3
Or at position more on the upper side.5th road and baffle plate 3 afterwards, which are then spaced, increases to 0.5-0.8m, and shape is still direct for bending plate
It is welded on inertial dust separator housing 11.In addition, the vertical size of baffle plate 3 is then to ensure the lower horizontal of last twice baffle plate 3
On the basis of position is less than the lower horizontal height of inertial dust separator air inlet 13.
The utility model is added before impact type water deduster according to dust characteristic, fluid motion feature etc..Enter in deduster
Mouth, into the larger particulate matter of particle diameter, slow down the horizontal movement of dust added with spray equipment, spray droplet with dust perikinetic aggregation
Speed, (dust of 20-50 μm of particle diameter is applied to, equipment resistance is in 300-800Pa, efficiency of dust collection with common inertial dust separator
50-70%) compare, the dust of 5-20 μm of particle diameter, efficiency of dust collection ＞ 85%, powder can be trapped added with the inertial dust separator of spray equipment
Dirt is discharged in dust collecting trough through ash bucket on the downside of inertial dust separator, and supernatant after precipitation is also recycled.
Fountain inertial dust separator (efficiency of dust collection ＞ 85%) is used as primary dust removing device, the utility model (efficiency of dust collection
95%) as two-stage dust removal device, then efficiency of dust collection when running simultaneously is：
η=1- (1- η1)(1-η2)=1-0.15 × 0.05=99.25%
If deduster need to only reach 99% efficiency of dust collection, the efficiency of dust collection for only needing water deduster is 93.3%.
The design greatly alleviates the operating load and increase deashing and exchange water cycle of follow-up water deduster, reduces water
The operating cost of deduster.Improved inertial dust separator investment and operating cost are relatively low, but can reduce the concentration of emission of flue gas
Used with the cost of overhaul in later stage.Fountain inertial dust separator small volume, designed size is carried out with specific reference to exhaust gas volumn and containing Dust Capacity,
Water spray is with exhaust gas volumn ratio in 7.5*10-5—9.0*10-5L/m3Most preferably.
The determination of inertial dust separator appearance and size, it is 10m/s, pipe that flue gas, which enters flue gas flow rate after fountain inertial dust separator,
Road internal diameter is d, then grit is in the time that vertical direction is fallen on the downside of pipeline from top：Then horizontal direction flue gas is transported
Dynamic distance is：L=v0T (does not consider that smoke flow resistance loses), v0：Flue gas horizontal direction speed, l:Inertial dust separator air-flow
The length in direction, m；Original width when inertial dust separator flue gas has just enter into is：The size of ash bucket is then dense according to flue gas
Degree, efficiency of dust collection, deashing time determine the volume of ash bucket.
The present embodiment is applied to before impact type water deduster, and the dust of removal about 85%, reduction are handled as primary dust removing
The operating load of water deduster, it is ensured that flue gas qualified discharge.
The utility model has the following advantages that：
1st, equipment design is simple, low manufacture cost；
2nd, equipment operation is simple, only needs ash bucket deashing periodically, the dust on baffle plate 3 be with plate at vapor coagulate
Drippage enters ash bucket and removed after knot；
3rd, handled suitable for the dust that flue gas content is larger or moisture vapor amount is larger；
4th, operation, maintenance cost are low, only need to change nozzle 22；
5th, the gas flow rate in equipment is 2-3m/s；
6th, the coagulation that equipment is only handled as water deduster or other Wet smokes.
Description of the present utility model is provided for the sake of example and description, and is not exhaustively or by originally
Utility model is limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.
Selection and description embodiment are, in order to more preferably illustrate principle of the present utility model and practical application, and to make the common skill of this area
