AI Technical Summary

Technical Problem

The lack of a multi-stage liquid distribution structure in existing falling film evaporators leads to uneven liquid distribution within the falling film tubes, which can easily cause localized drying or scaling.

Method used

It adopts a multi-stage liquid distribution structure, including a first liquid distribution plate and a second liquid distribution plate, with V-grooves and through holes for liquid distribution and quantitative flow. The liquid is introduced into the reboiler tube through the liquid distribution component, the baffle prevents the liquid from impacting at high speed, and the support component supports the reboiler tube to resist weight and thermal expansion stress.

Benefits of technology

It improves the uniformity of liquid distribution, avoids liquid stagnation, ensures accurate guidance of liquid to the reboiler tube, reduces reboiler tube sagging and displacement, and improves the stability and efficiency of the equipment.

Abstract

This utility model relates to the field of evaporator technology, specifically disclosing a falling film reboiler, including a tank body, a tank cover body disposed on the top of the tank body, and a tank bottom body connected to the bottom of the tank body; an installation plate is provided between the tank body and the tank cover body, and a second distribution plate and a first distribution plate are sequentially arranged on the top of the installation plate. The bottom of the first distribution plate is connected to a perforation through a first support, and the bottom of the second distribution plate is connected to the installation plate through a second support; in this utility model, the first distribution plate and the second distribution plate cooperate to distribute liquid. The first distribution plate receives the incoming liquid and distributes the liquid through the through hole at its bottom and the overflow at its top. The V-shaped groove can guide the liquid outflow and avoid liquid accumulation on the plate surface. The through hole realizes quantitative diversion and improves the uniformity of liquid distribution. The distribution element is used to guide the liquid into each reboiler tube to ensure that the liquid is accurately guided into the reboiler tube.
