Abstract

The utility model relates to a juice trap. A plurality of packing sleeves are designed, and the inside of the sleeve is filled with corrugated filler. Vapor passes through the corrugated filler and sleeve of which the upper side is in malposition with the lower side. Liquid droplet is separated out via the adhesion and inertia effect. The utility model has the advantages of simple structure, easy assembly, easy cleanness, less resistance, and high separation efficiency (more than (90%) and the little liquid droplet (diameter is more than 10 um) can be trapped. The utility model can be used for existing evaporators and crystallizing tanks.

Description

A kind of juice catching device

The utility model relates to food machinery and sugar manufacturing machinery technical field, is a kind of vapor-liquid separating device.

The secondary steam that is evaporated from liquid glucose (being commonly referred to juice vapour) steam flow is taken away tiny liquid foam together, is called " mist effect ".Evaporating pot and crystallizer all might be owing to the mist effect causes sugar loss.Mist runs sugar and not only causes sugar loss, and pollutes vapour and coagulate water, makes it can not do also to pollute the tail water of condenser into stove water usefulness, influences environmental health.Therefore evaporating pot and crystallizer all are provided with juice catching device (vapour liquid separator, entrainment trap).

A kind of juice effect interior juice catching device of corrugated baffle formula jar preferably of catching is arranged, and it belongs to the surface type juice catching device, and it has two or three layers of corrugated baffle to become 110 ° of inclinations to be formed by connecting, and is installed in juice steam chest in the evaporating pot.This juice catching device flow velocity is low and surface-area is big, and it is many to catch juice, and gas-flow resistance is little, but when steam flow speed is high weak effect, also undesirable to the separating effect of fine drop (as drop less than 10um).

Net formula juice catching device also is a juice catching device in a kind of surface type jar, makes which floor cylinder with the guipure that fine wire, plastics silk or resin silk are woven into, and is installed in juice steam chest in the evaporating pot.Steam flow by the time contact area very big, so it is better to catch the juice effect, can capture fine drop (as drop less than 10um), its separation efficiency can reach 85%.Its shortcoming is: stop up easily, clean difficulty.

The purpose of this utility model is a kind of jar of interior juice catching device of design, integrate surface type and inertia type, can install and use in existing evaporating pot or crystallizer, it can capture fine drop (droplet dia is more than 10um), the separation efficiency height, and be not easy to stop up and be easy to the mounting or dismounting cleaning.

The utility model is achieved in that several filler sleeves of design, loads filler in the sleeve, also designs the sleeve that some misplace up and down.Allow the steam that is entrained with drop by the packing layer in the filler sleeve, contact with the big area of filler and to make it adhesive attraction take place and vapor-liquid separation, gas after the separation is the sleeve by misplacing up and down again, drop is further separated with the sleeve wall collision by inertia effect, with the liquid collecting separated and be back to evaporating pot or crystallizer in, allow gas discharge from steam discharge pipe.

The utility model mounting or dismounting simple in structure, easy are cleaned, and resistance is little, and it can capture fine drop (droplet dia is more than 10um), separation efficiency height (more than 90%).Can in existing evaporating pot or crystallizer, install and use.

With accompanying drawing the utility model is further described below.

Accompanying drawing 2 vertical views

Inner sleeve 9 and outer sleeve 8 are installed on base plate 10, mounting center sleeve 1 between inner sleeve 9 and outer sleeve 8, cylindrical central sleeve 1 leaves base plate 10 certain altitudes, with housing 12 and orifice plate 6 with base plate 10, inner sleeve 9 and outer sleeve 8 cover, orifice plate 6 exceeds inner sleeve 9 and outer sleeve 8 certain distances, on orifice plate 6, open a centre hole and some filler sleeve holes, centre hole passes by cylindrical central sleeve 1, the filler sleeve hole is installed filler sleeve 3, filler sleeve 3 is laid filler 4, filler 4 can be the mesh ripple packing, perforated plate corrugated filler, silking ripple packing or other filler, adorn a central dispersion 7 in the filler sleeve 3, clamp ring of the usefulness suitable for reading of filler sleeve 32 is fixing, with seal washer 5 sealings, base plate 10 has inclination slightly between filler sleeve 3 and the orifice plate 6, and inner sleeve 9 and outer sleeve 8 paste the base plate place and have aperture, allow liquid collecting flow out, the low side of base plate 10 has the liquid collecting mouth and connects return line 11.

Earlier the utility model is installed on the top juice steam chest of vaporizer (or crystallizer) during use, allow the steam that is entrained with drop by clamp ring 2, enter filler sleeve 3, pass through filler 4 from top to bottom, juice gas is subjected to the adhesive attraction and the air filter effect of the very big filler of surface-area 4, droplets entrained is separated in the juice vapour, the small droplets of separating from juice vapour sticks on the filler 4, flow from top to bottom, aggegation becomes big drop, drop at last on the base plate 10, flow to return line 11 directions along base plate 10.The steam that comes out from filler 4, the U type passage of flowing through and forming by outer sleeve 8, cylindrical central sleeve 1 and inner sleeve 9, droplets entrained in the steam (majority is the drop of re-entrainment) is subjected to inertia effect to collide each sleeve wall and is further separated, these drops flow to downwards on the base plate 10 along barrel, conflux into return line 11 with the liquid collecting that filler 4 is separated, liquid collecting flow back in the vaporizer (or crystallizer) from return line 11.Worked behind the certain hour, can as required filler have been taken out from the filler sleeve and clean.

Application example (seeing attached Fig. 1 and 2):

Inner sleeve 9 and outer sleeve 8 are installed on a circular bottom plate 10, mounting center sleeve 1 between inner sleeve 9 and outer sleeve 8, cylindrical central sleeve 1 leaves base plate 200mm, with housing 12 and orifice plate 6 with base plate 10, inner sleeve 9 and outer sleeve 8 cover, orifice plate 6 and inner sleeve 9 and outer sleeve 8 are apart from 350mm, on orifice plate 6, leave a centre hole and 4 filler sleeve holes, centre hole passes by cylindrical central sleeve 1, the filler sleeve hole is installed filler sleeve 3, place mesh ripple packing 4 in the filler sleeve 3, a central dispersion 7 is laid at the middle part in the filler sleeve 3, seals with seal washer 5 between filler sleeve 3 and the orifice plate 6, with clamp ring 2 compressing filler sleeve 3, base plate 10 is tilted to the right, inner sleeve 9 and outer sleeve 8 are pressed close to the base plate place and are opened an aperture, allow liquid collecting flow out, and the right-hand member of base plate 10 has the liquid collecting mouth and connects return line 11.

This example is installed to the top of evaporator room in the vaporizer of sugar refinery vapo(u)rization system, evaporator area is 500m ²During work, the secondary steam (being commonly referred to juice vapour) that syrup explosive evaporatoin in the vaporizer produces is being carried the syrup drop secretly, at first pass through clamp ring 2, enter filler sleeve 3, the mesh ripple packing 4 of flowing through from top to bottom and designing in a zigzag, the surface-area of ripple packing is very big, utilize surperficial adhesion and air filter effect with the syrup drop separation, the juice steam flow that comes out from filler sleeve 3 bottoms is via outer sleeve 8, during " U " type passage that cylindrical central sleeve 1 and inner sleeve 9 formed, because inertia effect syrup drop is further isolated, the steam that contains micro-syrup at last flows out outside the device from the top outlet of cylindrical central sleeve 1.The syrup liquid that is separated comes together in base plate 10 and flows into return line 11 to the right, is back to vaporizer again.Worked after the press for extracting juice season, taken out filler 4 and clean.

This routine vapor-liquid separation efficiency reaches more than the 95-99%, and resistance is reduced to 0.2-0.7kPa.
