Abstract
The invention discloses a kind of multi-function fine foam removal and evaporate tower, including tower body, tower body top connects condenser and return tank, bottom connects reboiler, being mounted alternately with column plate and packing layer inside tower body from top to bottom, column plate is provided with downspout and downflow weir, and the filler of packing layer is by bracket support；Being provided with Despumation device between described column plate and packing layer, this Despumation device is the mesh grille using polytetrafluoroethylmaterial material to make.One aspect of the present invention reduces the shortcoming that plate column pressure drop is big, it is simultaneously also beneficial to vacuumizing, foam can be played restriction and fragmentation by Despumation device, need not additionally mounted demister, gas-liquid better contacts with in tower and carries out mass transfer and heat transfer, tower body can be manufactured into suitably sized as required, overcomes the defect that simple plate column is only applicable to the tower of minor diameter.
Description
Technical field
The present invention relates to Chemical Equipment Design field, particularly to a kind of Multifunctional rectifying column.
Background technology
Rectifying column is equipment most-often used in Chemical Manufacture, according to the structure type of gas-liquid contact part in tower, tower can be divided into plate column and packed tower, and they are respectively suitable in different Chemical Manufacture.Packed tower is the gas-liquid mass transfer (contact) equipment of continuous way, contacts and carry out mass transfer and heat transfer between gas-liquid two-phase in continuous flow upstream, and the concentration of gas-liquid two-phase component is consecutive variations along tower height.Successively counter current contacting carry out mass transfer and heat transfer between gas-liquid two-phase in plate column, the concentration of gas-liquid two-phase component is step variation along tower height.Packed tower simple in construction, pressure drop is little, it is simple to process corrosive materials, the material of foam easy to foaming and vacuumizing, but volume is big, weight is big, mass-transfer efficiency is relatively low, and operational stability is poor, be unsuitable for processing dirty liquid, dusty gas, containing solid particle and the material of easily fouling.And plate column carries out mass transfer and heat transfer by layering, on every block of column plate, gas-liquid two-phase must keep close and sufficiently contact, phase border contact surface that is sufficiently large and that constantly update is provided for mass transport process, reduce resistance to mass tranfer, make gas-liquid two-phase be counter-current flow tower planted agent, to provide the mass transfer power of maximum as far as possible.
Along with the development in pluralism of chemical products, simple packed tower or sieve-plate tower can not meet the demand of gas-liquid mass transfer, design pressure drop little, and disposal ability is big with operating flexibility, and rectifying column applied widely is the Tough questions faced of chemical industry.
Summary of the invention
For making up the deficiencies in the prior art, the present invention provides a kind of multi-functional foam removal rectifying column reasonable in design, applied widely.
The present invention is achieved through the following technical solutions:
A kind of multi-function fine foam removal evaporates tower, including tower body, tower body top connects condenser and return tank, bottom connects reboiler, it is characterized in that inside described tower body and is mounted alternately with column plate and packing layer from top to bottom, column plate is provided with downspout and downflow weir, and the filler of packing layer is by upper and lower two-layer bracket clamp standoff；Being provided with Despumation device between described column plate and packing layer, this Despumation device is the mesh grille using polytetrafluoroethylmaterial material to make；Described tower body last layer installs column plate, and basecoat installs packing layer, and feed entrance point is in the column plate layer in the middle part of tower body.
The multi-functional foam removal rectifying column of the present invention, the length of side of the mesh grille of described Despumation device is 0.5-1cm.
The multi-functional foam removal rectifying column of the present invention, use two-layer column plate and one layer of packing layer alternately to install in described tower body, the height of one layer of packing layer is 0.5-1m.
The invention has the beneficial effects as follows: on the one hand column plate reduces the shortcoming that plate column pressure drop is big with alternately installing of packing layer, it is simultaneously also beneficial to vacuumizing, foam can be played restriction and fragmentation by Despumation device, need not additionally mounted demister, gas-liquid better contacts with in tower and carries out mass transfer and heat transfer, tower body can be manufactured into suitably sized as required, overcomes the defect that simple plate column is only applicable to the tower of minor diameter.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the structural representation of Despumation device of the present invention.
In figure, 1 tower body, 2 condensers, 3 return tanks, 4 reboilers, 5 column plates, 6 downspouts, 7 downflow weirs, 8 Despumation devices, 9 packing layers, 10 brackets.
Detailed description of the invention
Accompanying drawing is a kind of detailed description of the invention of the present invention.This embodiment includes tower body 1, tower body 1 top connects condenser 2 and return tank 3, and bottom connects reboiler 4, and described tower body 1 is internal is mounted alternately with two blocks of column plates 5 and one layer of packing layer 9 from top to bottom, column plate 5 is provided with downspout 6 and downflow weir 7, and the filler of packing layer 9 is supported by bracket 10；Being provided with Despumation device 8 between described column plate 5 and packing layer 9, this Despumation device 8 is the mesh grille using polytetrafluoroethylmaterial material to make；Described tower body 1 last layer installs column plate 5, and basecoat installs packing layer 9, and feed entrance point is in the column plate 5 layers in the middle part of tower body 1, and the length of side of the mesh grille of Despumation device 8 is 0.6cm, and packing layer 9 height is 1 meter.
The present embodiment uses bubble point charging, sends in rectifying column after material liquid is heated to bubble point by preheater, and feed entrance point is in the column plate 5 layers in the middle part of tower body 1, it is ensured that material feeds from column plate layer, reduces and bubbles.Rise steam on tower body 1 top and use complete condenser condensation, condensed fluid is back in tower in bubble point next part, and remainder delivers to storage tank after reactor product cooler cools down, and does not set spray equipment in tower body 1, reflux inlet connects with ground floor column plate 5 in tower body 1, increases gas liquid interfacial area.Arranging reboiler 4 bottom tower body 1 and use indirect steam heating, bottom product delivers to storage tank after cooling.Bottom tower body 1, basecoat is packing layer 9, and liquid flows out tower body 1 through packing layer.
Plate column is combined with the advantage of packed tower by column plate 5 with alternately installing of packing layer 9, reduces pressure drop, it is adaptable to vacuumizing, and tower body 1 size can be designed as required, and Despumation device 8 eliminates the installation of demister, and cost-effective, the scope of application is wider.
