Technical field
The present invention relates to the required evaporation concentration equipment of industrial enterprise, be specially a kind of evaporating column.
Background technology
Evaporation is exactly: material is converted into the phase transition process of gaseous state from liquid (solid-state).The speed of its evaporation rate depends primarily on the factors such as temperature, pressure and specific area, relevant with air velocity, the concentration etc. of density, material top in addition, and wherein, the evaporant interface that flies out is governing factor.After temperature, pressure are determined by the process conditions of production unit, the specific area of increasing device inside how that what we can change is exactly.No matter be on the market several single-effect evaporators, or other tubular type, board-like, scraper-type evaporimeter are not all considered the problem that this is the most basic, what have is exactly to increase heat exchange area, strengthen steam consumption etc., and how consideration does not utilize the useful space, the specific area of increasing device inside, increases the time of staying, thereby improves evaporation efficiency.
Summary of the invention
For problem above, the invention provides a kind of evaporating column, in conjunction with the two advantage of packed tower and tubular heat exchanger, should be as the packed tower have enough large wetting face and a sufficiently long time of staying, in order to heat and mass, there is again larger heat exchange area, increase as much as possible wetting face, increase unit specific area, can't stop up filler because of evaporation and concentration.
Concrete solution is a kind of high-speed and high-efficiency evaporating column evaporating column, comprise tower body, manhole, flash steam outlet, evaporated liquor outlet, tubular heat exchanger, evaporated liquor import, above tubular heat exchanger, be provided with squama wing heating fumigators, squama wing heating fumigators include steam inlet, condensate outlet, upper header, lower collecting box and be communicated in upper header and lower collecting box between squama wing type heat pipe, squama wing type heat pipe is made up of with the squama fin that is arranged on central tube periphery and be fixedly connected with central tube central tube.
As preferably, above tubular heat exchanger, be provided with 2, three heat exchangers of two squama wing heating fumigators and mutually superpose, form a double effect evaporator.
As preferably, the squama fin being fixedly connected with central tube is circular ring plate.
As preferably, the squama fin being fixedly connected with central tube is metal tape, and metal tape is wrapped on central tube.
Beneficial effect: 1. efficient, energy-conservation, quick; (efficiency compared with shell and tube improve 2 ~ 3 times) 2. safe, controlled, continuous, automaticity is high; 3. be easy to maximize: both can use by separate unit, and can many parallel connections apply mechanically again; 4. of many uses: fusing point is 150
0non-heat-sensitive substance below C can be applied; 5. being difficult for wall built-up stops up; 6. simple and compact for structure, for ease of maintenaince to install, floor space is little; 7. without waste liquor contamination.

The specific embodiment
Below in conjunction with accompanying drawing 1 to 5, the specific embodiment of the present invention is described.
A kind of evaporating column, comprise tower body 1, manhole 4, flash steam outlet 51, evaporated liquor outlet 52, tubular heat exchanger 3, evaporated liquor import 6, above tubular heat exchanger 3, be provided with squama wing heating fumigators 2, squama wing heating fumigators 2 includes steam inlet 21, condensate outlet 24, upper header 22, lower collecting box 26 and is communicated in upper header 22 and the squama wing type heat pipe 23 of lower collecting box 26 heat pipe interfaces 25, and squama wing type heat pipe 23 is made up of with the squama fin 232 that is arranged on central tube 231 peripheries and be fixedly connected with central tube central tube.
Above tubular heat exchanger 3, be provided with 2, three heat exchangers of two squama wing heating fumigators and mutually superpose, form a double effect evaporator.The squama fin 232 being fixedly connected with central tube 231 is circular ring plate, as shown in Figure 4.
The squama fin 232 being fixedly connected with central tube 231 also can be made metal tape, and metal tape is wrapped on central tube 231, as shown in Figure 5.Tubular heat exchanger is made to spirally-wound type squama wing type heat pipe (outer appearance radiator), increase specific area, increase the time of staying, be increased in the fly out chance at interface of evaporant under uniform temperature, pressure, reach the effect of a packed tower.
In the time of processing squama wing heat exchanger, dense arrangement is as much as possible made an entirety on special processing work platform, and then entirety packs in tower, guarantees both quality and quantity.
Flake type squama wing heat pipe central tube inside is the steam of heating use, has so just solved the problem that filler stops up.Fusing point is 150
0the general vapor (steam) temperature of C() even if following material has wall cling phenomenon, open steam and just can make it to melt, self falling, can not stop up tower body filler.
Three heat exchangers superpose mutually, rise steam on bottom, and the lower liquid of heating upper temp, forms a double effect evaporator.Three heat exchangers can operate separately, can be controlled the temperature of upper, middle and lower portion respectively, reliable again flexibly.
At bottom settling section: by evaporant, in this crystallization sedimentation separation, clear liquid is used pump retrieval system from top, dope and crystal are discharged at the bottom of tower.
Bottom tubulation heating fumigators: for by the main bringing-up section of evaporated liquor, tubulation shell side is steam, and tubulation tube side is by evaporated liquor, evaporation is along inside pipe wall evaporation, and air-flow rises, and liquid declines.
Middle part squama wing heating fumigators: for by the evaporator main section of evaporated liquor.Evaporimeter is the heat pipe composition with squama wing by 60 ~ 112 (diameter difference, radical differences), walks steam in pipe, not only heating liquid but also can prevent from stopping up and wall built-up.Pipe is outer by evaporated liquor, and squama wing had not only conducted heat but also mass transfer, also can increase the time of staying.
Squama wing evaporation heater is the core of evaporating column, evaporation is mainly carried out at this, and evaporimeter forms (diameter difference, radical difference) by multiple heating tubes with squama wing, squama wing heating tube is made general part, the ring plate that is 1mm by 59 Φ, 100/ Φ 28 thickness, and one by Φ 25x3, the pipe composition of long 3000mm, annulus is through on pipe, spacing 50mm, and welding, also can replace annulus on metal tube with strip winding.Squama wing heating tube at right angle setting, two ends are connected on header, and in pipe, logical steam, in order to heating, is managed on outer and scale and is evaporated.
Material enters evaporating column top squama wing evaporation heater by liquid distributor spray, liquid is in interface and spray decline process, and constantly heating, evaporation, enter stage casing squama wing evaporation heater, continue again heating, decline, evaporate, liquid enters hypomere column tube evaporimeter, further heating, decline, evaporation, and dense magma is to settling section, isolate solid crystal at this, next workshop section is gone in evaporated liquor outlet, and clear liquid flows out from circulation port, returns to top inlet recycle with pump.The steam evaporating upwards flows from lower columns pipe evaporator, and constantly heating evaporation liquid is finally discharged from the outlet of top flashed vapour.
