To take demister as center of circle radius the be semi-circular front scope of 6 ~ 9 meters that the sphere of action of described sound wave demister is.
The present invention is owing to using above technical scheme, and the beneficial effect made it have is:
Absorption tower of the present invention section arranges one deck sound wave demister, device is except sonic generator sounding needs consumption of compressed air, without any need for power consumption, little droplet is condensed into the larger droplet particle of diameter under sound wave effect, thus removed by demister trapping, the solid content simultaneously in droplet also can largely reduce.After the effect of sound wave demister, in demister exiting flue gas, droplet content is generally lower than 20mg/Nm3, in droplet, solid content is reduced to 5% ~ 8%, demist dust removing effects clearly, and structure is simple, easy for installation, do not need additional floor, without rotating machinery in whole device, equipment small volume and less weight, the aperture opening diameter an about 100mm on the sidewall of absorption tower is only needed to install, whole device is arranged on the wall of absorption tower, do not need additional floor, no matter be grassroot project or transformation project, can easily install, long service life, without the need to maintenance repair, there is higher practical value.
Accompanying drawing explanation
Fig. 1 is the structural representation of sound wave demister of the present invention;
Fig. 2 is the absorption tower front view of sound wave demister of the present invention.
Detailed description of the invention
For the benefit of to the understanding of structure of the present invention, below think and coordinate drawings and Examples to be described.
Composition graphs 1 is with shown in Fig. 2, sound wave demister of the present invention, adopt low frequency high energy sound wave, be arranged on the support component on absorption tower wall 1, absorption tower wall 1 has a support component at least, sound wave demister comprises horn-like sound wave diffuser 2, sonic generator 3 and compressed air supply and purifier 4, horn-like sound wave diffuser 2 is located in tower, and fixed by bolt 5 and absorption tower wall 1, sonic generator 3 is located at outside tower, compressed air supply and purifier 4 comprise tube connector 41, pneumatic even part 42, y-type filter 43 and magnetic valve 44, the pneumatic part 42 that connects is provided with a Pressure gauge 45, in order to measure air pressure, pneumatic even part 42 is connected to one end of tube connector 41, y-type filter 43 was connected by articulation 46 with pneumatic company between part 42, and between articulation 46 and y-type filter 43, be provided with a ball valve 47, this ball valve 47 controls y-type filter 43, the other end of tube connector 41 is provided with magnetic valve 44, magnetic valve 44 is fixed by fixed head 48 and tube connector 41, wherein, sonic generator 3 is connected by a crossover sub 6 with tube connector 41, in order to adjust air pressure and air inlet, one end of sonic generator 3 is located in the entrance of absorption tower wall 1, and one end of tube connector 41 is provided with a switch valve 7 in the pneumatic outside connecting part 42, in order to control compressed-air actuated entering.
Shown in composition graphs 2; sound wave demister is generally arranged between spraying layer 7 and ground floor demister 8 or between ground floor demister 8 and second layer demister 9; during installation; on absorption tower wall 1, correct position opens 5 holes as illustrated in the drawing; tower outward part connects compressed air; when employing three layers of demister; the protection of sound wave demister is set between the second layer and third layer demister; or when adopting multilayer demister; offer multilayer demister, so that realize the protection of multilayer sound wave demister.
After installing this device, make compressed air enter tube connector 41 by the control of switch valve 7, flue gas enters absorption tower from absorption tower entrance 10, to take demister as center of circle radius the be semi-circular front scope of 6 ~ 9 meters that the sphere of action of often overlapping sound wave demister is; Desulphurization reaction is carried out under the spray effect of spraying layer 7, a large amount of slurries are entrained with in flue gas after desulphurization reaction, with slurries gas sound wave demister sonic generator 3 act under, drop gathering becomes the larger particle of particle diameter, part directly drops in slurry pool of absorption tower, and part enters demister below with flue gas and caught removal by demister.
Because " acoustic agglomerator " of sound wave acts on, little droplet is condensed into the larger droplet particle of diameter under sound wave effect, thus is removed by demister trapping, and the solid content simultaneously in droplet also can largely reduce.After the effect of sound wave demister, in demister exiting flue gas, droplet content is generally lower than 20mg/Nm3, and in droplet, solid content is reduced to 5% ~ 8%, and demist dust removing effects clearly.
Absorption tower of the present invention section arranges one deck sound wave demister, device is except sonic generator 3 sounding needs consumption of compressed air, without any need for power consumption, and structure is simple, easy for installation, do not need additional floor, without rotating machinery in whole device, equipment small volume and less weight, the aperture opening diameter an about 100mm on the sidewall of absorption tower is only needed to install, whole device is arranged on absorption tower wall 1, do not need additional floor, no matter be grassroot project or transformation project, can easily install, long service life, without the need to maintenance repair, there is higher practical value.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by appending claims and equivalent thereof.
