Another inner cylindrical canister body which acts as the air outlet pipe is arranged in the cylindrical canister body. The upper part of the inner cylindrical canister body is fixedly connected on an upper cover flange which is on the top of the cylindrical canister body, and the upper end of the inner cylindrical canister body extends out the upper side of the cylindrical canister body. The drain pipe is fixedly connected on a lower cover flange of the cylindrical canister body, and one to four drain pipes are equispaced. The lower end of the drain pipe extends out the lower side of the cylindrical canister body. A blocking liquid taper ring and an annular blocking liquid flanged edge are welded at the outer side of the lower part of the inner cylindrical canister body. The blocking liquid taper ring inclines downwards and situates on the annular blocking liquid flanged edge. Diversion trenches which are inclined downwards are equispaced and welded on the outer margin of the annular blocking liquid flanged edge. The diversion trenches have three to eight. An air diverter is also arranged in the lower end of the inner cylindrical canister body. The falling-film type column shaped cyclone demister has much smaller pressure drop, much higher efficiency of defogging, convenient installation and more reasonable structure.
Description
Technical field
The utility model belongs to whirlwind aerosol isolation technics, more particularly relates to the improvement of falling film type cyclone demister.
Background technology
The method and apparatus of droplet is a lot of in the existing divided gas flow, and inertia demister, cyclone demister, fiber filter demister, vortex-flow and defrosting device or the like are arranged.The advantage of said method and equipment has nothing in common with each other, and its shortcoming also has nothing in common with each other.The inventor's No. 01243741.7 name be called " straight down flow film demister " patent disclosure a kind of escape pipe bottom, its top of being positioned at cylindrical tube the novel falling film type cyclone demister that awl cap, discharging tube also are positioned at the cylindrical tube bottom is housed.Its pressure drop have only in the past 1/3rd, power consumption reduces greatly, can be widely used in the separating of liquid urea and gas in the melamine synthesis tail gas.
The purpose of this utility model, just be to draw said method and equipment advantage, overcome its deficiency, provide a kind of pressure drop littler, the power consumption and production cost lower, demist efficient is higher, the falling film type column cyclone demister of more reasonable structure.
Summary of the invention
In order to achieve the above object, the utility model comprises that cylindrical tube, the section that tangentially is connected cylindrical tube top are rhombus, rectangle or circular air inlet pipe, are connected escape pipe and discharging tube on the cylindrical tube.Suit another inner cylindrical tube body as escape pipe in the cylindrical tube.The upper flange that the top of inner cylindrical tube body is connected in the cylindrical tube top covers, and stretch out on cylindrical tube its upper end; The lower flange that discharging tube is connected in cylindrical tube covers, and stretch out below cylindrical tube its lower end.
During work, the fluid-mixing of liquid and gas is that rhombus, rectangle or circular air inlet pipe tangentially enter from the section on cylindrical tube top, rotation and descending.Because action of centrifugal force, contained drop is thrown toward barrel, and flows to the bottom along the barrel film forming, is discharged by discharging tube.The gas that has been cleaned enters the inner cylindrical tube body thereupon, discharges from inner cylindrical tube body upper end at last.In this separation process, droplet can obtain enough centrifugal force, thereby can obtain higher demist efficient.
Retaining liquid conical ring and ring-type retaining liquid flange are being welded in the outside, bottom of inner cylindrical tube body.Retaining liquid conical ring downward-sloping and be positioned at ring-type retaining liquid flange above.The external profile diameter of retaining liquid conical ring is less than the external profile diameter of ring-type retaining liquid flange.Uniformly on the outer rim of ring-type retaining liquid flange welding downward-sloping guiding gutter.The effect of retaining liquid conical ring is that the drop that will directly fall is collected also drainage to ring-type retaining liquid flange, is guided to inwall through guiding gutter again and compiles, and can avoid splashing simultaneously.Certainly, ring-type retaining liquid flange also has the effect of the drop that collection directly falls.
Guiding gutter can have 3～8, should depend on the needs according to the concrete size of demister and the parameters such as content of droplet.Be advisable with 3～8.
The gas flow guiding device also is installed in the lower end of inner cylindrical tube body, and it comprises the connection deflection cone that is welded on the inboard and uniform vertical blade in inner cylindrical tube body lower end, vertical blade is fixed together.The effect of gas flow guiding device is with the moving axial flow that changes into of the spiral upper upstream of gas.
Discharging tube can be 1～4, and the uniform lower flange that is connected in cylindrical tube covers.Should depend on the needs according to the concrete size of demister and the parameters such as size of lifting rate.
In the cylindrical tube, lower flange covers the anti-device that splashes also is installed, its structure can be a kind of in uniform gusset or grid or the silk screen.Its objective is and prevent, isolate and fall splashing of drop.
The anti-discharge opeing whirligig of being made up of vertical gusset can also be installed in the discharging tube.Anti-discharge opeing whirligig can impel discharge opeing axially to discharge, and avoids rotating.
Task of the present utility model comes to this and finishes.
Pressure drop of the present utility model is littler, and power consumption and production cost are lower, and demist efficient is higher, and it is reasonable that structure more becomes.It can be widely used in the various aerosol separation processes processes.
