Abstract
The utility model discloses a horizontally combined cyclonic scrubber paratactically combined by a big cyclonic cylinder and one or two small cyclonic cylinders side by side, which is used for the flue gas ash removal of the industrial boiler. The fume is rotated and separated in the big cyclonic cylinder, a portion of the fume is concentrated into high-concentration fume and then enters the small cyclonic cylinder to be rotated and separated, the dust particles separated are discharged through an oxhorn bent pipe, and the air-stream purified is merged with the air-stream purified in the big cyclonic cylinder and enters an induced air machine through an exhaust tube. Adopting the dust-removing structure of the two-stage dust removing of the small cyclonic cylinder and the oxhorn bent tube, the utility model has the advantages of high dust removing effect, compact structure, solving the back mixing and the secondary flying up of the dust-contained air-stream, and can reduce the height of the dust remover and can be directly connected with the induced air machine.
Description
The utility model relates to a kind of combined type cyclone dust collectors, specially refers to be evaporation capacity 1---20 tons/time Industrial Boiler supporting cyclone dust collectors.
The technological guidance of Ministry of Machine-Building Industry file: Industrial Boiler product planning standard (JB/Z218--84) is recommended 12 kinds of cyclone dust collectors.Cyclone dust collectors are included into planning standard, need through model test the performance measurement under hot operating condition.Require the efficient of deduster to be higher than 90%, flue gas resistance is lower than 785Pa.The employed cyclone dust collectors of prior art can be selected into the few in number of planning standard.In these cyclone dust collectors, the cylindrical shell that has is too high, needs connecting pipe long, and the bodily form that has is bigger, and steel quantity consumption is more, and the floor space that has is big.
The purpose of this utility model provides a series of new type cyclone dust collectors, and the efficient of deduster can reach 92～95%, the about 785Pa of flue gas resistance.Compact conformation, steel quantity consumption is low, 1000 meters of every purification flue gases
3In/time, need 40 kilograms of steel approximately.It can directly be connected with air-introduced machine, and the dust arrester connecting pipe is short, saves steel, saves the area, and easy for installation, the smoke treatment amount is big, stable performance.Wear-resistant paint has all been designed at deduster inwall position easy to wear, can move continuously for a long time.
The utility model is made of side by side willy-willy tube and whirly tube.The housing of willy-willy tube adopts accurate logatithmic spiral structure.The willy-willy tube is formed by connecting with flange by preceding whirlwind tube and back whirlwind tube.The central axis of willy-willy tube and whirly tube is parallel to each other, and is positioned on the plane.The willy-willy tube connects the whirly tube and adopts straight tube with the tangent rectangular cross section of two barrels.The whirly tube adopts the ash discharge structure of ox horn bend pipe, and the cone angle of every pipe joint section surface cone of ox horn bend pipe is 15 °.The whirly tube adopts the exhaust elbow of garden shape section to be communicated with the privileged site of willy-willy tube.There is a cone of protruding forward the central area of back whirlwind tube end plate, and its cone angle is 60 °.Be dry type horizontal cyclone deduster, be used for the flue gas ash removal of Industrial Boiler.
Belong to a total inventive concept, design 4 kinds of model combined type cyclone dust collectors.Their the structurally solitary characteristic of novelty performance is different from the cyclone dust collectors that China produces now.
Accompanying drawing has been described embodiment of the present utility model:
Accompanying drawing 1:XH I type cyclone dust collectors.
Accompanying drawing 2:XH II type cyclone dust collectors.
Accompanying drawing 3:XH III type cyclone dust collectors.
Accompanying drawing 4:XH IV type cyclone dust collectors.
Novelty of the present utility model shows and adopts the dedusting of three grades of whirlwind tubes on the contour structures.Preceding whirlwind tube (1) and back whirlwind tube (7) play a part inspissator with the willy-willy tube that flange connects to form, and flue dust is condensed into dense air-flow, enter with the good No. 1 whirly tube of separating property (3) again and capture flue dust.The flue gas of staying in the willy-willy tube continues to concentrate, and the flue gas after concentrating enters in No. 2 whirly tubes (9), increases the more catcher meeting of fine particle, to improve the efficient of deduster.The housing of willy-willy tube (1), (7) adopts accurate logatithmic spiral structure, has improved the operating mode of air-flow in the tube.Adopt being connected of willy-willy tube (1), (7) and whirly tube (3), (9) straight tube (2), (8) with the tangent rectangular cross section of two barrels, can arrange the relative position between them easily, can reduce the wearing and tearing of flue dust, solve the outlet of upper dust-ring tube wall.The cone angle of the ox horn bend pipe (4) of connection whirly tube (3), (9), every pipe joint section surface cone of (10) is 15 °, avoids producing down the ash ring.Particularly a cone angle that protrudes is forward arranged is 60 ° cone to whirlwind tube (7) base plate center, back, force the bottom of concentrated flue dust air-flow in cone, along with the straight tube (8) of the tangent rectangular cross section of barrel, tangentially enter in No. 2 whirly tubes (9), the dust of separating enters the flue-dust retainer from ox horn bend pipe (10), the top of the cone of the central area of whirlwind tube (7) base plate after flue gas after being purified is communicated with through exhaust elbow (11).This tail structure of deduster has improved the efficient of deduster, solves the influence to efficient of the back mixing of dust-contained airflow and secondary fly-up, can reduce the setting height(from bottom) of deduster, makes compact conformation, and reduced volume is in light weight.
Accompanying drawing 2 is the air inlets that the exhaust elbow (5) of No. 1 whirly tube (3) in the accompanying drawing 1 changed into the preceding whirlwind tube (1) of feeding, and the change in size of flue gas flow and each parts is little.
Accompanying drawing 3 is that the exhaust elbow (5) with No. 1 whirly tube (3) in the accompanying drawing 1 changes into backward, all be communicated with the central area of whirlwind tube (7) base plate afterwards with the exhaust elbow (11) of No. 2 whirly tubes (9), converge with the air-flow that has purified in the tube, break away from deduster through the garden of preceding whirlwind tube (1) tubular core pipe (6), enter fan inlet, the size constancy of most parts.
Accompanying drawing 4 is that No. 1 whirly tube (3) in the accompanying drawing 1 is saved, and adopts the dedusting of secondary whirlwind tube, and simplified structure is saved steel.The high velocity air that contains flue dust tangentially enters in the preceding whirlwind tube (1), utilizes the centrifugal force of high velocity air rotation, and flue dust is gathered to barrel, and air-flow spreads attenuation backward simultaneously.Air-flow enters in the back whirlwind tube (7), grit continues to gather to barrel, the dirt nuclear that concentrates and a small amount of flue gas (equal or be slightly larger than total exhaust gas volumn of 10%) tangentially enter in the whirly tube (9) along the straight tube (8) with the tangent rectangular cross section of barrel, continuing rotation separates, the grit of separating enters in the flue-dust retainer through ox horn bend pipe (10), air-flow after the purification enters the central area of back whirlwind tube (7) through exhaust elbow (11), converge with the air-flow that has purified in the tube, the garden tubular core pipe (6) of whirlwind tube (1) breaks away from deduster before entering, and enters the air inlet of air-introduced machine.
