Abstract
The utility model relates to chemical heating equipment which belongs to the technical field of chemical machinery equipment. The utility model comprises a feed opening, a discharge opening, a heating medium inlet, a heating medium outlet and heating media, and also comprises a high efficiency mixed distribution machine and a reboiler, wherein the high efficiency mixed distribution machine and the reboiler are connected into an integral body. The feeding opening and the heating medium inlet are positioned on the high efficiency mixed distribution machine, and the discharge opening and the heating media outlet are positioned on the reboiler. The utility model is used in the process of rectifying isopropanolamine products. A falling film type reboiler is used for a tower, the bottom temperature of which is beyond 150 DEG. The high efficiency mixed distribution machine is designed before materials enter a heating pipeline, so the falling film type reboiler causes liquid materials to form film downward flow in a heating pipe. The heat transferring efficiency is improved, the heat transferring temperature difference which is required by film boiling is little, the temperature requirement of the heating media is low and the heating temperature which the product bears is low.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, and the utility model relates to a kind of chemical industry firing equipment more precisely.Belong to the chemical mechanical equipment technical field.
Background technology
Because isopropanolamine product particularly two different and triisopropanolamines is heat sensitive materials.The high temperature heating that runs into more than 170 ℃ just may produce decomposition.Thermosyphon reboiler is all adopted in isopropanolamine series of products rectifying before.Thermosyphon reboiler is owing to must there be certain material could form thermal siphon, the height of material forms certain pressure reduction, increased boiling temperature, also increased simultaneously the time of staying of thermal material at the tower still, isopropanolamine product of Sheng Chenging and two different tower bottoms colors are darker like this, accessory substance is more, sometimes two different tower bottoms even may produce waste residue.
Summary of the invention
The purpose of this utility model is to provide a kind of the reduction heating-up temperature of isopropanolamine product material in distillation process and the time of staying of material, reduces production of by-products, improves the color and luster of product and the device of purity.
The utility model is to take following technical scheme to realize:
The falling film type reboiler comprises charging aperture, discharging opening, heat medium import, heat medium outlet and heat medium; It is characterized in that it also comprises efficient distributor and reboiler, described efficient mixed distribution device and reboiler are connected as a single entity, and charging aperture and heat medium import are positioned on the efficient distributor; Discharging opening and heat medium outlet are positioned on the reboiler.
Utilize the utility model in the distillation process of isopropanolamine product, the tower that the still temperature is surpassed 150 ℃ adopts the falling film type reboiler, the falling film type reboiler is owing to designed efficient mixed distribution device before material enters water back, it is membranaceous dirty that liquid material is formed in heating tube, heat transfer efficiency improves greatly, the heat transfer temperature difference that film boiling needs is little, and the temperature requirement of heat medium is low, and the heating-up temperature that is subjected to of product is just low like this.Simultaneously, behind the use falling film evaporator, tower still residence time of material is short, and it is colourless to make that product colour approaches, and does not have production of by-products.
Description of drawings
Fig. 1 is the structural representation of the present thermosiphon reboiler that uses;
Fig. 2 is the structural representation of the utility model falling film type reboiler.
The specific embodiment
The utility model falling film type reboiler as shown in Figure 2, wherein charging aperture (1), discharging opening (2), heat medium import (3), heat medium export (4), heat medium (5), efficient mixed distribution device (6) and reboiler (7), described efficient mixed distribution device and reboiler are connected as a single entity, and charging aperture and heat medium import are positioned on the efficient distributor; Discharging opening and heat medium outlet are positioned on the reboiler.Utilize the utility model in the distillation process of isopropanolamine product, the tower that the still temperature is surpassed 150 ℃ adopts the falling film type reboiler, the falling film type reboiler is owing to designed efficient mixed distribution device before material enters water back, it is membranaceous dirty that liquid material is formed along tube wall in heating tube, heat transfer efficiency improves greatly, the heat transfer temperature difference that film boiling needs is little, and the temperature requirement of heat medium is low, and the heating-up temperature that is subjected to of product is just low like this.Simultaneously, behind the use falling film evaporator, tower still residence time of material is short, and it is colourless to make that product colour approaches, and does not have production of by-products.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
