Technical field
The present invention relates to field of environment protection equipment, particularly a kind of smoke eliminator.
Background technology
Containing certain density droplet (the general 75mg/Nm of flue fog drip concentration in heat-engine plant wet desulfurization fume exhaust3), being entrained with in Gypsum Fibrosum (Gypsum Fibrosum accounts for 20%), the particularly droplet of big particle diameter gypsum content in droplet more can not be ignored, and the dust in smoke evacuation there are about half and carries secretly from droplet. In order to reduce dust emission further, reaching " the ultra-clean discharge of flue dust " requirement, it is necessary for arranging high efficiency demister at desulfurizing tower rear portion flue.
Existing mist separator of desulfurization (no matter being demister or tower external flue formula demister in tower) is only effective to big droplet, and the little droplet of below 20um cannot be removed. In order to reduce soot emissions further, it is common practice to arrange wet electrical dust precipitator after desulfurizing tower, removed flue dust and droplet by the mode of extra electric field.
It is the droplet of more than 20um that conventional desulfurization demister is only capable of elimination particle diameter, and the little droplet of below 20um is helpless, and rinses frequently, and water consumption is big. Although wet electrical dust precipitator is higher except mist, efficiency of dust collection, but floor space is big, it is necessary to high voltage supply, and power consumption is high, and water consumption is big, and cost is high. Although screen type demister demisting efficiency is higher, but not easily rinses, it is easy to blocking, desulphurization system is difficult to application; Prior art is unresolved such problem also.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention done concrete introduction.
The degree of depth removes mist dust arrester, including: air inlet smoke box 1, the droplet dammed and adsorb in air inlet smoke box 1 and the rotation filter bed 6 of flue dust, reception is through the smoke box 7 of giving vent to anger of the gas of over-rotation filter bed 6, and submergence rotates filter bed 6 one end and also cleans the water cleaning assemblies 9 rotating filter bed 6.
Rotate filter bed 6 composition to have: be connected to air inlet smoke box 1, the housing 3 of smoke box 7 of giving vent to anger, be placed in the cyclic transfer assembly in housing 3, the filter bed 6 of parcel cyclic transfer assembly. In order to allow flue gas uniformly enter rotation filter bed 6, improve filter efficiency, between air inlet smoke box 1 and rotation filter bed 6, be provided with airflow uniform distribution plate 2. The number rotating filter bed 6 is indefinite, rotates filter bed 6 and is at least one, can increase and decrease as required. Cyclic transfer assembly composition has: two drive sprockets 4 being placed in filter bed 6 two ends, connects the chain 5 of drive sprocket 4, is connected to drive sprocket 4 driven sprocket 8 driving filter bed 6 to move. Motor drives drive sprocket 4 to rotate, and drives chain 5 and driven sprocket 8 to transmit, and driven sprocket 8 is connected in filter bed 6, thus driving filter bed 6 transmission. When filter bed 6 moves to the position of bottom tank, it is achieved clean, the flow direction of flue gas is perpendicular to rotation filter bed 6, so ensure that the filter bed 6 of contact flue gas is all clean, and bedewed water, rely on " air-flow conveying+filter bed 6 retains+moisture film absorption, adhesion " combined effect, make gas cleaning. The lower submerged of filter bed 6, in the tank of bottom, had both facilitated the flushing of filter bed 6, also made bottom water seal air tight simultaneously. Tank is provided with nozzle, makes filter bed 6 rinse cleaning.
Filter bed 6 composition has: at least one piece of silk screen intercepter plate 11, connects the otic placode 13 between silk screen intercepter plate 11 and chain 5, is connected to the PTFE flexible cloth 12 between silk screen intercepter plate 11; Silk screen intercepter plate 11 composition has: silk screen layer, the framework 10 of carrying silk screen layer; Silk screen layer is made up of at least one of which silk screen, and the thickness of silk screen layer is 5-100mm. Such design makes polylith silk screen intercepter plate about 11 coaxial rotating, is linked to be seamless entirety by PTFE filter cloth between silk screen intercepter plate 11.
Water cleaning assemblies 9 includes: bottom tank, connects the internal pipeline between the tank of bottom, is placed in the nozzle on the tank of bottom; In order to saving water resource, the degree of depth removes mist dust arrester, also includes: be connected to the water circulation use assembly of water cleaning assemblies 9.
The work process of this device is: after (a) flue gas enters device, after air inlet smoke box 1 and air-flow uniform board 2, and droplet and flue dust are along with the flowing " hitting " of flue gas is to rotating filter bed 6; B () flue gas flows through rotation filter bed 6 after, droplet and flue dust are dammed and are absorbed; In adsorption process, it is filled with, owing to silk screen intercepter plate 11 is internal, the droplet absorbed, enhances filtration and the absorbability of silk screen intercepter plate 11 so that during normal operation, the degree of depth increases substantially except the mist rate of removing of mist dust arrester, it is possible to effectively remove by minimum droplet; C (), under the drive of drive sprocket 4 and chain 5, filter bed 6 rotates along (inverse) hour hands. Rotate to silk screen intercepter plate 11 entrance of bottom tank to clean specially, after rinsing well, return flue gas flow channel; D the pollutant in () flushing water, are processed by external water circulation use assembly, the clean also reuse of the water after process; It should be noted that water circulation use assembly is that the half being commercially available on market recycles assembly. Through such process, this device droplet clearance >=90% to more than 3um, filter bed 6 drag overalls≤300Pa.
This device arranges and rotates filter bed 6 and invade the water cleaning assemblies 9 not rotated bottom filter bed 6, not only makes filter bed 6 be cleaned in time, and realizes dynamic dedusting except mist; The flow direction of flue gas is vertical with filter bed 6, relies on " air-flow conveying+filter bed 6 retains+moisture film absorption, adhesion " combined effect, makes gas cleaning; Smoke content < 5mg/Nm after process3, reach the requirement of minimum discharge; The sulfuric acid mist of elimination major part simultaneously, reduces the risk of successor devices corrosion and blocking, extension device service life; This device can remove 3um and above ultra-fine droplet and dust, and demisting efficiency is up to more than 90%. Water cleaning assemblies 9 be connected to outside water circulation use assembly, compared with existing purifier, volume be only its 30%, take up an area space little, cost economize, resistance is low, and water consumption is few, wastewater flow rate is little. The Maintenance and Repair of this device are convenient, except can only silk screen layer be replaced when fog effect is deteriorated.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described. Skilled person will appreciate that of the industry, above-described embodiment does not limit the present invention in any form, and all employings are equal to the technical scheme that the mode of replacement or equivalent transformation obtains, and all fall within protection scope of the present invention.
