Abstract
The present invention relates to a guide rectifier for a spiral-flow cycle dust-removing system, which belongs to a separation and dust removal technique. The circulating-current cycle dust-removing system is composed of a two-stage spiral-flow cyclone dust collector. Each stage comprises an outer cylindrical body, an inner cylindrical body, a tapered cylindrical body, a dust discharge pipe, an end socket, an exhaust pipe and an air inlet pipe. The upper end of the outer cylindrical body of the first stage is connected with a columnar cyclone separation column. A guide rectifying plate comprises blades and a guide cone, wherein the blades are evenly distributed and are welded at the inner side of the lower end of the columnar cyclone separation column; the blades are fixedly connected with the guide core; the blades and a horizontal surface form an elevation angle alpha; the upper end and the lower end of the guide core are both in a streamline shape; the number of the blades can be 3 to8. When the elevation angle alpha of the blades and the horizontal surface is from 10 to30 degrees, guide rectifying effect is the best. The blades can also be in an arc shape, and an elevation angle alpha of a tangent line of the blades and the horizontal surface is between 10 to30 degrees. The guide rectifier for a spiral-flow cycle dust-removing system can eliminate a fishtailing phenomenon of fluid and rule a flow shape, so dust removal efficiency is greatly improved. A division diameter of the spiral-flow cycle dust-removing system can reach 0.33 to0.66 mum. The guide rectifier for a spiral-flow cycle dust-removing system can be widely applied to all kinds of industrial fields needing sub-micron grade dust removal.
Description
Technical field
The invention belongs to circulation cycle dedusting technology field, more particularly relate to the design of the water conservancy diversion rectifier of circumfluent cyclone system.
Background technology
The applicant's ZL01243742.5 patent disclosure a kind of " circulation type circulating-dedusting system ".It is made up of the two-stage circumfluent cyclone, and each level all has outer cylinder body, inner barrel, conic tube, ash releasing tube, end socket, blast pipe and air inlet pipe.The outer cylinder body upper end of the first order connects column cyclonic separation post, and its top sides wall is communicated with partial air inlet pipe.Partial blast pipe returns the first order by blower fan and is communicated with its air inlet pipe.Its efficiency of dust collection can reach more than 98%, and can remove the following dust of 0.5 μ m.But it yet exists following deficiency: 1. lack of standardization column cyclonic separation Duan Zhongliu shape; 2. in the conic tube position fluid phenomenon of wagging the tail.These 2 all have certain influence to efficiency of dust collection.
Purpose of the present invention just is to provide a kind of and can overcomes above-mentioned deficiency, and the phenomenon of wagging the tail of energy eliminate fluid makes its stream shape standard, the water conservancy diversion rectifier of the circumfluent cyclone system that efficiency of dust collection improves greatly.
Summary of the invention
In order to achieve the above object, the present invention is installed in the inside, lower end of the column cyclonic separation post of circumfluent cyclone system.Circumfluent cyclone system is made up of the two-stage circumfluent cyclone, and each level all comprises outer cylinder body, inner barrel, conic tube, ash releasing tube, end socket, blast pipe and air inlet pipe.The outer cylinder body upper end of the first order connects column cyclonic separation post, and its top sides wall is communicated with partial air inlet pipe.Partial blast pipe returns the first order by blower fan and is communicated with its air inlet pipe.The water conservancy diversion rectifier comprises and is welded on column cyclonic separation post lower end central intake pipe inboard and uniform blade and the deflection cone that blade is fixed together.Blade becomes angle of elevation alpha with horizontal plane.
After installing the water conservancy diversion rectifier additional, air-flow is through over commutation, and spiralling inclination angle reduces, and rotating cycle increases, the path lengthening.But its average axial velocity in column cyclonic separation post is constant, that is its time of staying in splitter is constant.Therefore, its tangential velocity increases, and dust has also just obtained bigger centrifugal force.Efficiency of dust collection has also just improved certainly greatly.
The upper/lower terminal of deflection cone is streamlined.The deflection cone of streamline structure makes the tapering type water conservancy diversion rectifier that flows through of fluid, and involute flows out the water conservancy diversion rectifier then.In this course, fluid has been eliminated the phenomenon of wagging the tail by current stabilization, and flow pattern is tending towards standard, and fluid spiralling inclination angle change, and efficiency of dust collection is further enhanced.
When blade was 3～8, effect was better.The quantity of blade should depend on the needs according to the concrete size of column cyclonic separation post, the dustiness of fluid and the parameters such as designed capacity of circumfluent cyclone system.Be advisable with 3～8.
When blade and angle of elevation alpha that horizontal plane becomes=10～30 °, the inclination angle that flow spiral rises is comparatively suitable.When spiralling inclination angle was excessive, rotating cycle reduced, the path contraction of air-flow.Its tangential velocity also reduces, and the suffered centrifugal force of dust also just reduces.Efficiency of dust collection has just reduced certainly.When spiralling inclination angle was too small, because the average axial velocity of dust-contained airflow in column cyclonic separation post is constant, that is its time of staying in splitter was constant.Therefore, its tangential velocity increases, and turbulence intensity increases, and be unfavorable for dedusting on the contrary, cause efficiency of dust collection to reduce, and pressure drop increases.
Blade also can be arc, its tangent line and angle of elevation alpha that horizontal plane becomes=and 10～30 °.Arc shaped blade helps shaping, the current stabilization of fluid, can further eliminate the phenomenon of wagging the tail, and makes stream shape standard more, and efficiency of dust collection also will be further enhanced.
Task of the present invention comes to this and finishes.
The phenomenon of wagging the tail of the present invention's energy multimode eliminate fluid makes flow pattern standard more, thereby has improved efficiency of dust collection greatly.When air-flow velocity during at 26～32m/s, efficiency of dust collection is the highest.The present invention can make the dividing diameter d of system
50Value reaches 0.33～0.66 μ m, has obtained unexpected effect.It can be widely used in the various industry that need the submicron order dedusting, the environmental protection field.
