Abstract
The utility model discloses a dry type high efficiency combined cyclone dust collector, comprising a high efficiency cyclone dust collector [5]. The utility model is characterized in that the utility model also comprises a low-resistance dust collector [4] and a rough dust collector [2], the high efficiency cyclone dust collector [5] is placed in the logarithmic spiral-shaped low-resistance dust collector [4], is connected with the logarithmic spiral-shaped rough cleaner [2] through a fume pipe [11], the dry type high efficiency combined cyclone dust collector is composed of the high efficiency cyclone dust collector, the low-resistance dust collector and the rough dust collector which are connected in series, the dust collection efficiency is over 96%, and the resistance force is about 980-1176 Pa. The utility model has the advantages of simple structure, high reliability and low cost and is suitable for the dust collection of the high-temperature fume of the fluidized bed furnace, etc.
Description
The utility model is that a kind of dry type efficiently makes up cyclone dust collectors, belongs to the B01D class.
Dry type high efficiency cyclonic dust collector commonly used both at home and abroad is that a kind of structure is the simplest, its principle is to utilize the air-flow rotation to produce centrifugal force, grit in the ash-laden gas is thrown on the deduster cylindrical wall, slipping to the awl bucket along barrel catches, reliable, keeping in repair easyly, is the most cheap a kind of cleaner of price.During cold conditions, efficiency of dust collection is generally between 85～94%, if when being used for the higher stove gas cleaning of temperature, efficient difficulty is stabilized in more than 90%, and it is environmental requirement (400～1000 milligrams/mark rice that does not reach national defined that this simple single cylinder cyclone dust collectors are used on the fluidized bed furnace as cleaner
3).Except the dry type high efficiency cyclonic dust collector, the cleaner that is used for fluidized bed furnace also has stratum granulosum, cloth bag, electric precipitation, wet dedusting etc., but cost is all higher, floor space is big, the maintenance management complexity, there are different specification requirements and apparent method dedusting need solve water and mud secondary pollution problem again.At China's national situation, national energy structure at no distant date, the decision coal is China's main fuel, and China have again large quantities of in, dant and gangue, adopt fluidized bed furnace to think combustion system preferably if will make full use of these energy, therefore, solve the dust removal problem of fluidized bed furnace, making its environmental requirement that reaches national regulation, is a problem demanding prompt solution.
The purpose of this utility model is that the dedusting for fluidized bed furnace provides a kind of dry type efficiently to make up cyclone dust collectors, makes it can reach the environmental requirement of national regulation.
Solution of the present utility model is on the basis of high efficiency cyclonic dust collector, also comprise a low-resistance deduster and a rough cleaner, high efficiency cyclonic dust collector be placed in top with steel plate make, the bottom is with in the spiral low-resistance deduster of the logarithm of brick one-tenth, connect with the brick logarithm spirality rough cleaner that becomes by flue, the three is together in series and forms a kind of dry type and efficiently make up cyclone dust collectors, and its efficiency of dust collection reaches more than 96%.
The utility model comprises high efficiency cyclonic dust collector, it is characterized in that it also comprises a low-resistance deduster and a rough cleaner, high efficiency cyclonic dust collector be placed in top with steel plate make, the bottom is with in the spiral low-resistance deduster of the logarithm of brick one-tenth, by flue and the brick logarithm spirality rough cleaner connection that becomes.The three is together in series and forms a dry type and efficiently make up cyclone dust collectors, and its efficiency of dust collection reaches more than 96%, and resistance is 980～1176 handkerchiefs, and simple in structure, and volume compact is easy to make, and reliable, maintenance management is simple, low price.Simultaneously, be placed in the low-resistance deduster the sub-deduster of efficient cyclone according to the tonnage of fluidized bed furnace different configurable two or more.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is an A-A cutaway view of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model comprises high efficiency cyclonic dust collector (5), it is characterized in that it also comprises a low-resistance dust remover (4) and a rough cleaner (2), high efficiency cyclonic dust collector (5) be placed in top with steel plate make, the bottom is with in the spiral low-resistance dust remover of the logarithm of brick one-tenth (4), by flue (11) and brick logarithm spirality rough cleaner (2) connection that becomes. Simultaneously, the high efficiency cyclonic dust collector (5) that is placed in the low-resistance dust remover (4) can dispose two or more according to the tonnage of fluidized bed furnace is different. The fluidized bed furnace flue gas is after pipeline enters smoke inlet of the present utility model (1), after rough cleaner (2) removes lower bulky grain flue dust, discharged by top, enter flue (11), turn to 90 ° and enter low-resistance dust remover (4) by low-resistance dust remover entrance (3), carry out the second dedusting, and bypass ash chamber (9) arranged at flue gas rotating 360 degrees place, the medium grain flue dust namely removes lower at this, and then enter several (4 as shown in the figure) high efficiency cyclonic dust collectors (5) further except lower tiny flue dust, regularly put ash entrance chamber (10) by Vent ash sealing valve disc (7) then, again by spiral ash hoist (8) will except under flue dust transport out, this high efficiency combined vortex duster efficient can reach more than 96%, and resistance is between 980～1176 handkerchiefs.
The utility model adopts dry method dust, than high efficiency cyclonic dust collector efficient height, can be used for the higher fluidized bed furnace flue gas ash removal of temperature, efficient is more than 96%, and resistance has reached the environmental requirement of national regulation between 980～1176 handkerchiefs, lower than costs such as electric precipitation, cloth bag, wet dedustings, and pollution-free transfer, simultaneously, have again take up an area little, compact conformation, be easy to make, the characteristics such as maintenance management is simple also are suitable for the higher flue gas ash removal of other temperature.
Embodiment
The utility model construction is simple and reliable, and the bottom is two logarithm spirality brick settings, and one is rough cleaner (2), and one is low-resistance deduster (4) base, and inner surface is hung steel wire and smeared cement mortar again, and outer surface is smeared cement mortar.Low-resistance deduster (4) base top is that 3～4 millimeters steel plates making spiral low-resistance dedusters of logarithm (4) connect with pre-buried flange on the brick setting with thickness, go out to be placed in inner high-efficiency dust remover (5) number of low-resistance deduster (4) by fluidized bed furnace tonnage various computing, present embodiment is that 6 tons of/hour fluidized bed furnaces are laid 4 situation.Gang up mutually in order to prevent several high efficiency cyclonic dust collectors (5) afterbody, a Vent ash of ad hoc meter sealing valve disc (7), regularly Vent ash ash entrance chamber (10) by the spiral ash hoist (8) of ganging up low-resistance deduster (4) base and rough cleaner (2), is transported out deduster with dust and is transported again.
