Description

A kind of cyclonic inertia deduster with double isolation wards

Technical field

The present invention relates to a kind of dust separation processing machinery, specially a kind of cyclonic inertia dedusting with double isolation wards Device.

Background technology

In the industries such as various boilers, catalyst, flour, milk powder, cement, weaving, chemical industry, it is necessary to being scattered in air Dust, that is, be generally in heterogeneity, irregular and unbalanced compound movement state dust carry out separating treatment, it is existing Laying dust is not miscellaneous in itself for conical cyclone deduster, will not block, and resistance is stable, and maintenance management is convenient, but due to needing inside and outside formation Rotary motion, so whole dust remover resistance is larger, power consumption is of a relatively high, poor for the separating capacity of fine dust.

The content of the invention

Big for existing conical cyclone dust remover resistance, power consumption is high, for fine dust separating capacity difference the problem of, this Invention provides a kind of cyclonic inertia deduster with double isolation wards, and its is simple in construction, and dust can be promoted to reach effective point From efficiency of dust collection is high.

Its technical scheme is such：It includes dedusting cylinder, and the dedusting cylinder is to pass through top cylinder body and bottom The closed cylinder of cylinder composition, air inlet, and the air inlet and the top are equipped with the top cylinder body The tangent connection of cylinder, blast pipe is provided with the top of the top cylinder body, and the blast pipe stretches into the top cylinder body Inside, the blast pipe are provided with exhaust outlet, and the position of the air inlet is less than the position of the exhaust outlet, the bottom cylinder Body bottom is connected with dust-precipitator, it is characterised in that：Spiral helicine bypass chamber one is provided with the top cylinder body, under described Portion's cylinder is provided with spiral helicine bypass chamber two, and top is provided with core pipe in the top cylinder body of the blast pipe, Baffle plate is installed in the core pipe, the baffle plate lower end is equipped with fixed plate, and core pipe lower end interval is provided with guide vane, Outlet necking short tube is installed in the guide vane lower end, cone cylinder is connected between the top cylinder body and bottom cylinder Body.

It is further characterized by：Sawtooth is carried on the baffle plate, fixed plate and guide vane；

The guide vane in a angle tilts arrange, a span is 50 ° ~ 80 °, and the guide vane lower end with The top cylinder body bottom maintains an equal level；

The outlet necking short tube is located in the conic tube, and is in taper wide at the top and narrow at the bottom corresponding to which.

The invention has the advantages that spiral helicine bypass is correspondingly provided with respectively on top cylinder body and bottom cylinder Room one, bypass chamber two, it is ensured that moving the grey ring to be formed in dedusting cylinder internal rotation can be sufficiently formed and keep complete, and except Bispin vortex air flow is formed in dirt cup body, promotes dust to reach and efficiently separates, so as to improve efficiency of dust collection, and dusty gas is cut To entering, deduster is simplified, and coarse dust is thrown toward wall in top cylinder body because centrifugal force is larger, falls with outer helical down current Enter in ash bucket, fine dusts are collided on guide vane when near core pipe because inertia force acts on, and are repelled to top Cylinder periphery of inner wall, drop to ash bucket in company with coarse dust, so as to add the ability of trapping fine dusts, in guide vane Lower end is equipped with taper outlet necking short tube, interfering with each other between down current and ascending air can be reduced, after final purification Gas drains into air via the toothed baffle plate of core pipe, and so as to obtain the superfine product of narrow particle size distribution, the pressure loss is small, processing It is large-minded, substantially increase production efficiency and economic benefit.

Embodiment

As shown in Fig. 1 ~ Fig. 3, the present invention includes dedusting cylinder, and dedusting cylinder is to pass through top cylinder body 2 and bottom cylinder The closed cylinder that body 10 forms, is equipped with air inlet 1, and air inlet 1 and top cylinder body 2 are tangent on top cylinder body 2 Connection, is provided with blast pipe 12, blast pipe 12 is stretched into inside top cylinder body 2, set on blast pipe 12 at the top of top cylinder body 2 There is an exhaust outlet, the position of air inlet 1 is less than the position of exhaust outlet, is provided with top cylinder body 2 in communication spiral helicine Bypass chamber 1, spiral helicine bypass chamber 29 in communication, i.e. bypass chamber 1, bypass chamber are provided with bottom cylinder 10 29 be spiral shape isolation ward；The inner top of top cylinder body 2 close to blast pipe 12 is provided with core pipe 3, and gear is provided with core pipe 3 Plate 4, the lower end of baffle plate 4 are equipped with fixed plate 5, and the lower end interval of core pipe 3 is provided with guide vane 7, and guide vane 7 is in tilted layout in 60 °, And the lower end of guide vane 7 maintains an equal level with the bottom of top cylinder body 2；Outlet necking short tube 8, top are installed in the lower end of guide vane 7 Conic tube 13 is connected between cylinder 2 and bottom cylinder 10, outlet necking short tube 8 is located in conic tube 13, and with its phase It is in taper wide at the top and narrow at the bottom to answer ground；Bottom cylinder 10 is connected with dust-precipitator 11, on baffle plate 4, fixed plate 5 and guide vane 7 With sawtooth.

In the present invention, dusty gas rotates 180 ° along air inlet 1 and tangentially enters top cylinder body 2, and coarse dust is because of centrifugation Power is larger, is thrown toward the inwall of top cylinder body 2, is fallen with outer helical, and fine dusts are when near core pipe 3 because of inertia masterpiece With collision on guide vane 7, and it is repelled to the periphery of inner wall of top cylinder 2, declines in company with coarse dust, so as to add The ability of fine dusts is trapped, taper outlet necking short tube 8 is housed in the lower end of guide vane 7, to reduce down current with rising Interfering with each other between air-flow；Bypass chamber 1, bypass chamber 29 are twist located on top cylinder body 2 and bottom respectively simultaneously On cylinder 10, it is ensured that being sufficiently formed and keeping for grey ring is complete, and bispin vortex air flow can be formed in dedusting cylinder, promotes powder Dirt, which reaches, to be efficiently separated, so as to improve efficiency of dust collection, that is, when dusty gas obtains rotary motion in dedusting cylinder, on Under be formed separately vortex pair motion, and by upper and lower swirling air stream formed up and down two grey rings in the center of top cylinder body 2 demarcate, Upper swirling air stream forms forms ring by relatively thin, lighter dust, into the bypass chamber 1 of top cylinder body 2, equally, under Swirling air stream forms the ring being made up of thicker, heavier dust, and the big gas of dust content is concentrated near wall, i.e., bottom is justified The bypass chamber 29 of cylinder 10, remaining dust along outer wall downdraught band to dust-precipitator 11, gas and dust in bypass chamber via The introducing body of dedusting cylinder body outer wall, dust fall into dust-precipitator 11, the return air inlet of conic tube 13（It is not drawn into figure）Introduce body Flue gas, impacted, separated again, the gas after purification into air-flow by new again when blast pipe 12 is flowed near return air inlet Body drains into air via toothed baffle plate 4 in core pipe 3 by the exhaust outlet of blast pipe 12, so as to obtain the ultra-fine of narrow particle size distribution Product, the pressure loss is small, and processing is large-minded, substantially increases production efficiency and economic benefit, and be particularly suitable for use in the non-fibre of purification Tie up shape dryness dust and the bigger occasion of dust content.
