Abstract
The utility model discloses a cyclone dust removing device used for a circulating fluidized bed furnace. The device comprises a dust remover, and a wind guide sleeve arranged at the upper end of the dust remover. A wind inlet hole is formed on the side surface of the upper part of the dust remover; a dust outlet hole is formed on the bottom the dust remover. The device further comprises two supporting arch frames for supporting and fixing the wind guide sleeve are arranged below the wind guide sleeve; the supporting arch frames are made of refractory materials, two ends thereof are fixed on the dust remover; the wind guide sleeve is made of refractory materials; a dust remover casing, a refractory layer, and a dust removing insulation layer are arranged in the dust remover from the exterior to the interior. The utility model has the beneficial effects of adopting the wind guide sleeve and the supporting arch frames which are made of refractory materials, and greatly reducing the manufacturing cost of the whole device and prolonging the service life of the whole device because the refractory has the advantages of good corrosion resistance performance and low cost.
Description
Technical field
The utility model relates to a kind of dust arrester, particularly a kind of CFBB cyclone dust collector.
Background technology
Current, existing CFBB cyclone dust collector on the market, the general heat-resisting alloy that adopts of its ventilating duct part is made, ventilating duct is welded on the shell of dust arrester then, though it is comparatively simple to do manufacture craft like this, the cost of manufacture height, and owing to attach some etchant gases and flue dust in the dust, so in the process of dedusting, ventilating duct can constantly be corroded, and has reduced the service life of ventilating duct greatly.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of low cost of manufacture, the CFBB cyclone dust collector of long service life.
In order to solve the problems of the technologies described above, CFBB cyclone dust collector of the present utility model, comprise deduster, place the ventilating duct of deduster upper end, the side on the top of deduster is provided with air inlet, the bottom is provided with the dust outlet, comprise that also two are positioned at the ventilating duct lower end in order to support and the fixing support bow member of ventilating duct, described support bow member is made by refractory material, and its two ends are fixed on the deduster; Described ventilating duct is also made by refractory material.
CFBB cyclone dust collector of the present utility model, described deduster are provided with deduster housing, dedusting flame retardant coating and dedusting heat-insulation layer from outside to inside successively.
CFBB cyclone dust collector of the present utility model, described ventilating duct are to be built by laying bricks or stones by quarl to form, and described support bow member also is to be built by laying bricks or stones by quarl to form.
The beneficial effect that the utility model is obtained is: adopt the ventilating duct of being made by refractory material and support bow member, because the corrosion resistance and good of refractory material, and low price, therefore greatly reduce the manufacturing cost of whole device and the service life of having improved whole device.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the cutaway view of A-A face.
Among the figure: 1, air inlet; 2, ventilating duct; 3, support bow member; 4, deduster; 5, deduster housing.
6, dedusting flame retardant coating, 7, the dedusting heat-insulation layer.
The specific embodiment
As depicted in figs. 1 and 2, CFBB cyclone dust collector of the present utility model, comprise deduster 4, place the ventilating duct 2 of deduster 4 upper ends, the side on the top of described deduster 4 is provided with air inlet 1, the bottom is provided with dust outlet 8, also comprise two support bow members 3 that are positioned at ventilating duct 2 lower ends in order to support fixation ventilating duct 2, described support bow member 3 is made by refractory material, and its two ends are fixed on the deduster 4; Described ventilating duct 2 is also made by refractory material; Described deduster 4 is provided with deduster housing 5, dedusting flame retardant coating 6 and dedusting heat-insulation layer 7 from outside to inside successively; Described ventilating duct 2 is to be built by laying bricks or stones by quarl to form, and described support bow member 3 also is to be built by laying bricks or stones by quarl to form.
After the flue gas that contains dust of boiler combustion generation tangentially enters dust arrester from air inlet, under the effect of ventilating duct 2, make the inwall rotation of flue gas along deduster 4, dust in the middle of the flue gas drops to deduster 4 bottoms by centrifugal force, discharges from dust outlet 8; The flue gas of separated flue dust is then discharged from lower to upper from the center of ventilating duct 2, enters boiler and carries out heat exchange and absorb energy.
Because all having quarl to build by laying bricks or stones, the support bow member 3 of ventilating duct 2 forms, and the corrosion resistance of quarl is very strong, price is also cheap a lot of with respect to high temperature alloy, so this practical New Cycle fluidized-bed combustion boiler cyclone dust collector is low price not only, and long service life, be easy to apply.
