Abstract
The utility model discloses a polyester rectifying tower. The polyester rectifying tower comprises a tower body, wherein the tower body is coated with a heat insulation layer; a prefractionation layer, a rectification layer, and an evaporation reboiling layer used for evaporating liquid into gas are arranged inside the tower body from top to bottom; both the prefractionation layer and the rectification layer are fixed in a framework container; a cobblestone layer is paved at the bottom of the framework container; a packing layer is placed on the cobblestone layer; the evaporation reboiling layer comprises a tower plate, and a plate type heat exchanger mounted on the tower plate; a steam outlet is formed in the top of the tower body; a steam inlet is arranged at the bottom of tower body; a liquid inlet is formed in the side surface of the top of the tower body; a filter is mounted in the liquid inlet.
Description
Technical field
The utility model belongs to polyester resin production field, is specifically related to a kind of rectifying column.
Background technology
Rectifying column is the tower vapor-liquid contacting apparatus of one that carries out rectifying, steam enters at the bottom of by tower, the gas phase evaporating and decline liquid carry out counter current contacting, two contact, volatile (low boiling) component in decline liquid constantly shifts in gas phase, difficulty volatilization (higher boiling) component in gas phase constantly shifts in decline liquid, gas phase more approaches tower top, its volatile components concentration is higher, and at the bottom of decline liquid more approaches tower, its difficult volatile component is more enrichment, thereby reaches the object that component separates.In the liquid that existing rectifying tower underflow goes out, include and have raffinate and callable liquid simultaneously, if therefore directly the fluid discharge at the bottom of tower is fallen to cause waste, therefore people adopt reboiler to heat the callable liquid of part, are flashed to gas and again send in tower body; Reboiler the complexity that has increased whole device of spiral-screen column is set, and increased floor space; Meanwhile, the heat insulation effect of existing rectifying column tower body is bad, easily causes heat to run off, waste resource; Filler in rectifying layer in existing rectifying column easily in use with tower body extrusion damage, cause filler slag to fall into pipeline, finally affect the running of the pump housing.
Utility model content
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of polyester rectifying column, the function of reboiler that it is integrated, and therefore floor space is little, has simplified the structure of whole device of spiral-screen column; The utility model polyester rectifying column also has the saving energy, the non-damageable advantage of packing layer.
The utility model solves the technical scheme that its technical problem adopts: polyester rectifying column, comprise tower body, described tower body outer wrap arranges heat-insulation layer, and described tower body inside is provided with just steamed layer from top to bottom, rectifying layer and the evaporation that liquid evaporation is become to the gas layer that boils again;
Described just steamed layer and rectifying layer are all fixed in a frame container, and one deck cobblestone layer is laid in the bottom of this frame container, on cobblestone layer, is placed with packing layer; The described evaporation layer that boils again comprises tower tray and is installed on the disc heat interchanger on tower tray;
The top of above-mentioned tower body offers steam (vapor) outlet, and the bottom of tower body arranges steam inlet, and the top-side of tower body offers inlet, in this inlet, filter is installed.
Further: in above-mentioned heat-insulation layer, be equipped with vapours pipeline.
Further: the cobblestone of above-mentioned cobblestone layer is in the same size, its diameter range is 4～5cm.
Further: above-mentioned evaporation boil again layer comprise multilayer tower tray, disc heat interchanger is all installed on every layer of tower tray, tower tray is fixedly installed in tower body inside.
The utility model compared with prior art has the following advantages:
The utility model polyester rectifying column, below rectifying layer, certainly be preferably positioned at tower body bottom simultaneously and be provided with the evaporation layer that boils again, on the liquid that tower body flows out and lower to disc heat interchanger, carry out heat exchange with the heat medium in disc heat interchanger, thereby can again flash to gaseous state by callable liquid, again utilize, saved the energy, also the function of traditional reboiler is integrated in to tower body inside simultaneously, make whole device of spiral-screen column floor space little, designs simplification; Meanwhile, the utility model increases the heat insulation effect of tower body by heat-insulation layer being set separately to tower body outside, has overcome the defect of traditional tower body loss heat; The utility model is also installed filter at inlet place, filter filters residue liquid, has avoided residue to enter tower body, and the distillation process of tower body is exerted an influence;
The utility model is not fragile in order to guarantee the filler of first steamed layer and rectifying layer, is provided with cobblestone layer below packing layer, and it has arrived buffering packing layer, avoids the rear residue of packing layer damage to fall into the phenomenon of pipeline.
