Abstract
The utility model discloses an acetate recovery distillation column with a heater, which comprises a column body and the heater arranged inside the column body. The heater is a steam heater which is arranged above the bottom of the column. The steam heater comprises at least one steam distribution pipe. One end of the steam heater penetrates through the lateral side of the column body and is provided with a steam inlet. Openings which correspond to materials in the column are arranged on the steam distribution pipe. The conventional heater in the prior art is omitted, and a predesigned steam heater is introduced to replace the original heater. Steam enters the steam heater through the steam inlet and jet out through the openings of the steam heater so that the steam directly contacts with materials in the recovery distillation column to carry out heat and mass exchanges, namely, to carry out mixing direct heat exchange. The steam heater is simple in manufacture, low in cost and mainly made of stainless pipes, welding rods and the like. The use of the steam heater not only guarantees normal or better running of the acetate recovery distillation column but lowers the cost thereof greatly.
Description
Technical field
The utility model relates to the firing equipment of organic wastewater recovery centrifugal station in a kind of acetate industry, relates in particular to a kind of recovery rectifying column that has heater that is specifically designed to.
Background technology
The heater that uses in the existing recovery rectifying column roughly is divided into three kinds of dividing wall type, hybrid, heat accumulating types.Reclaim rectifying and generally adopt the dividing wall type heater, and the dividing wall type heater is the most general with shell-and-tube heat exchanger (reboiler), submerged coil heat exchanger.Characteristic according to institute adaptive technique field; It is water that acetate reclaims the most of composition of the handled material of rectifier unit, adopts the direct contact heat-exchanging mode of dividing wall type heater feasible, even even more ideal; But; Existing dividing wall type heater, in textural more complicated, and the price of this type of heater is comparatively expensive like shell-and-tube heat exchanger, submerged coil heat exchanger.
Summary of the invention
The utility model is in order to overcome the deficiency of prior art; Provide a kind of acetate that has heater to reclaim rectifying column; Especially to reclaiming the transformation of the heater in the rectifying column, be intended to production cost and input cost in order to reduce acetate, the recovery rectifying column of the utility model is being guaranteed under the prerequisite of unit normal run; Design a steam heater simple in structure, easily manufactured and replaced original shell-and-tube heat exchanger and submerged coil heat exchanger.
The utility model solves the technical scheme that its technical problem adopted: a kind of acetate that has heater reclaims rectifying column; Comprise the heater that is provided with in tower body and the tower body; Wherein aforesaid heater is a steam heater of being located at top at the bottom of the tower; Steam heater is made up of at least one distribution of steam pipe, and an end of steam heater passes the tower body sidepiece and is provided with the steam inlet, and the distribution of steam pipe is provided with the opening of material in the corresponding tower.The utility model is through removing heater of the prior art; Introduce a pre-designed steam heater in the tower body middle and lower part and replace original heater; Steam gets into steam heater through the steam inlet; Steam directly contacts from the opening ejection of the steam heater material inner with reclaiming rectifying column and carries out heat exchange, matter exchange, promptly carries out hybrid direct heat transfer.
As the further design to the aforementioned techniques scheme: aforesaid steam heater is made up of cross two or four distribution of steam pipes, the bottom of every distribution of steam pipe evenly is provided with the corresponding material of opening.Promptly sidewall has been installed cross steam heater in the left and right sides of tower body, and the material of distribution of steam pipe is a stainless steel, and the pipe end of every distribution of steam pipe is fixed on tower body and gets on the outer wall.In rectifying column, be provided with liquid distribution trough above the steam heater, when producing, the noise that steam heater produced is very little, and the noise that sends than the reboiler of esterification column is little a lot.
The external diameter of aforesaid distribution of steam pipe is 159mm, and the width of opening is 50mm, and the distance between the adjacent apertures is 160mm.
Aforesaid steam heater is located on the position apart from 200mm at the bottom of the tower.
In sum; It is to replace original dividing wall type heat exchanger (shell-and-tube or submerged coil heat exchanger) with a steam heater that the acetate of the utility model reclaims the heater that is provided with in the rectifying column; Steam heater is made simple, and main material is stainless steel tube, welding rod etc., and cost is low.The use of steam heater can normally or better move by ensuring equipment, greatly reduces equipment cost again.In addition; Owing to reclaim rectifying column heat exchange method is changed to hybrid direct contact heat-exchanging by wall-type heat exchange; Satisfy the requirement of heat exchange fully, the low-grade flash steam that produces in the time of can rationally utilizing acetate system high-temperature condensation water to reclaim carries out heat supply, and can reduce equipment cost again; Can make the low-grade energy of by-product be fully used energy efficiency again.

Fig. 3 is that A-A among Fig. 2 is to profile.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further to describe explanation.
Embodiment 1
The concrete scheme of present embodiment is: a kind of acetate that has heater reclaims rectifying column; Like Fig. 1, Fig. 2, shown in Figure 3; Comprise the heater 2 that is provided with in tower body 1 and the tower body; Heater is a steam heater of being located at top at the bottom of the tower, and steam heater is welded into cross by four distribution of steam pipes 3, and the bottom of every distribution of steam pipe evenly is provided with opening 5 corresponding materials.A distribution of steam Guan Yiduan in the steam heater passes the tower body sidepiece and is provided with steam inlet 4, and the bottom of every distribution of steam pipe all evenly is provided with many openings of material in the corresponding tower, and the pipe end of every distribution of steam pipe is fixed on tower body and gets on the outer wall.The utility model is through removing heater of the prior art; Introduce a pre-designed steam heater in the tower body middle and lower part and replace original heater; Steam gets into steam heater through the steam inlet; Steam directly contacts from the opening ejection of the steam heater material inner with reclaiming rectifying column and carries out heat exchange, matter exchange, promptly carries out hybrid direct heat transfer.
The external diameter of aforesaid distribution of steam pipe is 159mm, and the width of opening is 50mm, and the distance between the adjacent apertures is 160mm.
Except that the embodiment of above structure, every and solvent sampler the utility model structural similarity falls within the protection domain of the utility model too.
