Abstract
The utility model relates to a tangential evolute long cylinder type multi-pipe dust remover, which is characterized in that a fume exhaust chamber is provided with air outlets with five directions; a cyclone in a cyclone separating chamber is arranged between the staircase-shaped hole plates; each layer of the cyclone is arranged through adopting the equal height and the equal distance, and the inclination angle of the ash bucket of the dust-collecting chamber is greater than 50 DEG. The air inlet of the cyclone is the tangential evolute type; the length of the cylinder is two to three times of the diameter of the cylinder, and the junction of the cylinder body and the conic body is cast with an annular reinforcing rib. The tangential evolute long cylinder type multi-pipe dust remover has the advantages that the distribution of the air flow is uniform; the dust removing efficiency is greater than 95%; the resistance is 800 to 1000 pa; the structure of the integral device is novel; the sealing is tight; the performance is stable, and the installation is convenient. The tangential evolute long cylinder type multi-pipe dust remover is suitable for the multi-pipe dust remover for the smoke and dust treatment of all kinds of boilers.
Description
The utility model belongs to the equipment that separates dispersed granules by gravity, inertia, centrifugal force from gas, the tangential involute air inlet of particularly a kind of employing, and whirlwind has the cyclone dust collectors of the multitube assembled arrangement of longer cylindrical shell.
The cyclone separating multi-tube dust cleaner is a home and abroad dry dust removal method commonly used.Be mainly used in the smoke and dust treatment of various boilers, and be widely used in the smoke and dust treatment of industries such as metallurgy, chemical industry, industrial furnace, ore and cement, have small investment, advantage such as volume is little.But traditional multi-tube dust cleaner adopts the axial admission pattern, when the higher air-flow of dust content enters, easily form clogging phenomenon, and the distribution inequality causes efficiency of dust collection low (60～80%), continues it, minor diameter has appearred, high-speed whirlwind subtype formula is used for deduster, efficiency of dust collection is significantly improved, but the life-span of this kind deduster shorten greatly, still undesirable.
The purpose of this utility model is, design and produce the long cartridge type multi-tube dust cleaner of a kind of tangential involute, adopt tangential involute air inlet, the pattern of flat underside, long tube, increase thickness and hardness at whirlwind position easy to wear, by contour ladder permutation and combination, to improve efficiency of dust collection, increase the service life, adapt to multiple field and use.
The long cartridge type multi-tube dust cleaner of tangential involute of the present utility model, form by smoke evacuation chamber, cyclone separating chamber, dust storage chamber three parts, be provided with total air inlet, air outlet and total ash discharging hole, it is characterized in that, the smoke evacuation chamber is arranged on the top of cyclone separating chamber, make forward, backward, left, to the right or upwards five kinds of direction air outlets of air-out, to adapt to the needs of various different users; Cyclone separating chamber's side direction is provided with total air inlet, whirlwind is installed between the upper and lower two-layer stepped orifice plate, every layer whirlwind adopts contour equidistant arrangement, to meet the flow direction of flue gas, between orifice plate and the boxboard, seal construction is taked in the sub-installation position of orifice plate and whirlwind, guarantee not leak out, so that obtain best mass transfer effect; Dust storage chamber is located at the bottom of cyclone separating chamber, and the inclination angle of the ash bucket of dust storage chamber is designed to greater than 50 °, promptly greater than 45 ° of the maximum angles of repose of dust, dust can be trapped on the boxboard of ash bucket, guarantees that ash discharge is smooth and easy; To the dust storage chamber of relatively large deduster, the ash bucket wallboard is provided with vertical and horizontal grid type dividing plate, and is moving to prevent the air-flow string; The air inlet of whirlwind is tangential involute-type, and flat underside, tube length are 2～3 times of barrel dliameter, at cylindrical shell and cone junction surface, are cast with ring stiffener.
Using method of the present utility model is, the dust-contained airflow that boiler is discharged, it is indoor at first to enter cyclonic separation through total air inlet, flow into by in each whirlwind of contour equidistant arrangement by tangential direction equably according to the flow of flue gas direction, rely on the centrifugation principle, dust is separated from air-flow, via the taper ash bucket of each whirlwind fall into smoke evacuation indoor after, discharge through total ash discharging hole,, be provided with vertical in the dust storage chamber to relatively large deduster for avoiding causing the air-flow crossfire in the dust storage chamber and mix and return, transverse grid type dividing plate, can prevent that the air-flow string is moving, at this simultaneously, the flue gas that has been cleaned, then to rise to smoke evacuation via the inner core pipe indoor, converge after discharge by total air outlet, the flue gas of discharging is through flue, and blower fan etc. enter chimney, are discharged in the atmosphere to go.
The utility model has the advantages that, adopt tangential involute air intake, longer cylindrical shell whirlwind, whirlwind adopts the method for arranging of contour arrangement simultaneously, has overcome the influence of flue gas crossfire effectively, and distribution of air flow is even, efficiency of dust collection is greater than 95%, and resistance is at 800～1000Pa.Whirlwind adopts the cast iron manufacturing, and position easy to wear has increased thickness and hardness, and it is long to have a life-span, anti abrasive characteristics.Flue gas is discharged and is adopted five direction patterns, makes it flexible for installation.The integral device volume is little, and is in light weight, takes up an area of to lack, and price is low; Novel structure, sealing is tight, and stable performance is easy for installation.Be applicable to the multi-tube dust cleaner that the smoke and dust treatment of various boilers is used.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of the long cartridge type multi-tube dust cleaner of tangential involute
Fig. 2 is the organigram of whirlwind of the long cartridge type multi-tube dust cleaner of tangential involute
As seen from the figure, the long cartridge type multi-tube dust cleaner of tangential involute of the present utility model, form by smoke evacuation chamber, cyclone separating chamber, dust storage chamber three parts, be provided with total air inlet, air outlet and total ash discharging hole, it is characterized in that, smoke evacuation chamber 1 is arranged on the top of cyclone separating chamber 2, makes front, rear, left and right and five air outlets 4 of air-out that make progress, to adapt to the needs of various different users; Cyclone separating chamber's side direction is provided with air inlet 5, whirlwind 6 is installed between the upper and lower two-layer stepped orifice plate 7, every layer whirlwind adopts contour equidistant arrangement, to meet the flow direction of flue gas, between orifice plate and the boxboard, seal construction is taked in the sub-installation position of orifice plate and whirlwind, guarantee not leak out, so that obtain best mass transfer effect; Dust storage chamber 3 is located at the bottom of cyclone separating chamber, and the inclination angle of the ash bucket 8 of dust storage chamber is designed to greater than 50 °, promptly greater than 45 ° of the maximum angles of repose of dust, dust can be trapped on the boxboard of ash bucket, guarantees that ash discharge is smooth and easy; The air inlet of whirlwind 6 is tangential involute-type 10, and flat underside 9, tube length are 2～3 times of barrel dliameter, at cylindrical shell 11 and cone 12 junction surfaces, is cast with ring stiffener 13.
