Abstract
The utility model relates to an installation connecting structure for a distillation tower and a condensator of distillation equipment, which is used for departments of petroleum, chemical industry, light industry, food, metallurgy, and the like. The installation connecting structure comprises the distillation tower (2), a reboiler (1) and the condensator (3) and is characterized in that the condensator (3) is directly installed on the top of the distillation tower (2). After adopting the connecting structure, the whole distillation equipment can realize higher vacuum degree, and the boiling point of materials is also correspondingly lowered, thereby the temperature of the whole distillation equipment can be also correspondingly lowered, and the cost is also greatly lowered.
Description
(1) technical field
The utility model relates to a kind of rectifying device, is specifically related to a kind of rectifying column of rectifying device and the mounting connection structure of condenser.Be widely used in departments such as oil, chemical industry, light industry, food, metallurgy.Belong to the rectifying device technical field.
(2) background technology
Rectifying be a kind of utilize to reflux make liquid mixture obtain the distillating method of high purity separation.It is industrial most widely used liquid mixture lock out operation.In practice, the general structure of rectifying column as shown in Figure 1.Form by rectifying column 2, reboiler 1, condenser 3 and connecting line etc.Rectifying column steam supply liquid two contacts and carries out interphase mass transfer, and the condenser that is positioned at the rectifying column cat head makes gas obtain partial condensation, and the part lime set in the condenser is returned the rectifying column cat head as phegma 3.1, and all the other distillates are overhead products 3.2.The reboiler that is positioned at the bottom of the rectifying Tata is partly vaporized liquid, and gas rises along rectifying column, and remaining liquid is as bottom product 1.1.Charging is added in the middle part of rectifying column.The liquid that liquid in the charging and rectifying section come descends along tower together, and the gas that gas in the charging and stripping section come rises along tower together.In whole rectifying column, interphase mass transfer is carried out in the contact of vapour-liquid two phase countercurrent flow.Volatile components in the liquid phase enters vapour phase, and the relative high boiling component in the vapour phase changes liquid phase over to.
The core of distillation process is to reflux, and the heating of condensation and reboiler must consume big energy.Cutting down the consumption of energy is the key subjects of distillation process development.By the principle of rectifying column as can be known, condenser is to realize condensation of gas, generates the equipment of overhead product and phegma, and crucial effects is played in circulation for rectifying column inside gas-liquid.
In the rectifying device that generally uses, condenser is to be arranged separately in the rectifying column outside now.Because the tube side loss, condenser is so that whole rectifying device can't be realized higher vacuum, so the boiling point of material is higher, and entire equipment need be finished rectifying under higher temperature, and this has increased the expense of heating widely.Because the refrigeration costs of condenser and heating expense portion in the whole operation expense of reboiler are bigger, thereby thereby the operating efficiency of therefore improving condenser reduces its energy consumption, reduces the heating expense that system temperature reduces reboiler, and huge economic benefit all can be brought for production in these aspects.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the rectifying column of the rectifying device that a kind of temperature of whole rectifying device can both corresponding reduction and the mounting connection structure of condenser are provided.
The purpose of this utility model is achieved in that a kind of rectifying column of rectifying device and the mounting connection structure of condenser, comprise rectifying column, reboiler and condenser, described condenser is directly installed on the rectifying column top, gas enters condenser by tower inside, the backflow that produces directly flows into rectifying column downwards, by the return channel control reflux ratio of rectifying column inside.
The rectifying column of the utility model rectifying device and the mounting connection structure of condenser, described reboiler is directly installed on rectifier bottoms.Liquid enters rectifying column once more through after boiling flow into reboiler in tower after again.
The rectifying column of the utility model rectifying device and the mounting connection structure of condenser, described reboiler can be arranged separately in the outside of described rectifying column.
The utility model is by being directly installed on condenser at the rectifying column top, reduced resistance to air-flow, pressure reduction between can reducing at the bottom of rectifying column cat head and the tower, reduce the pressure of operating at the bottom of the tower, thereby can lower bubble (boiling) point of solution at the bottom of the tower, reduce the operation of entire equipment temperature, reduce requirement, can also prevent the decomposition of bottoms material the rectifying column heating agent.
After adopting the utility model syndeton, whole rectifying device can be realized higher vacuum, the also corresponding reduction of the bubble of material (boiling) point, thus the temperature of whole rectifying device can both correspondingly reduce, and expense also reduces greatly.Meanwhile, temperature is lower during owing to rectifying, goes for the labile product of rectifying high temperature.In addition, lower rectification temperature also can reduce accident, has improved the security of integral device greatly.Meanwhile, condenser directly is placed in the rectifying column top, has saved the space of laying condenser, reduced the floor space of equipment, further save production cost.
