Problems solved by technology

[0002] The material of the existing falling film evaporator enters the upper head of the falling film evaporator at a saturated temperature state. Because the pressure of the liquid column decreases, saturated steam will flash out immediately, resulting in an increase in the pressure of the upper head, and the upper head and the vapor-liquid separation chamber The pressure difference increases, causing the material to flow faster in the heating tube, which is prone to serious erosion and wear of the heating tube

Embodiment Construction

[0014] Now in conjunction with accompanying drawing, the present invention is described in detail:

[0015] figure 1 Shown is the structural representation of the present invention. The present invention is composed of a pressure balance pipe (1), a pipeline (2), an upper head (3), a heating pipe (4), and a vapor-liquid separation chamber (5), wherein the lower end of the heating pipe (4) is placed on the steam In the liquid separation chamber (5), the upper head (3) is placed on the heating tube (4), and a pressure balance pipe (1) is connected between the upper head (3) and the vapor-liquid separation chamber (5), Pipeline (2) is installed on the upper head (3).

[0016] Working principle of the present invention:

[0017] In the present invention, a pressure balance pipe (1) is arranged between the upper head (3) and the vapor-liquid separation chamber (5) of the falling film evaporator, and the steam evaporated from the material entering the upper head (3) at a saturate...

Abstract

A falling-film evaporator balance device comprises: a pressure balance tube, a pipeline, an upper head, a heating tube and a vapor-liquid separation chamber, wherein the lower end of the heating tube is disposed in the vapor-liquid separation chamber, the upper head is disposed on the heating tube, the pressure balance tube is connected between the upper head and the vapor-liquid separation chamber, and the pipeline is mounted on the upper head. Pressure between the upper head and vapor-liquid separation chamber in the evaporator is balanced, reducing erosive wear of a heating tube bundle of the evaporator from material.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a pressure balance device for a falling film evaporator. Background technique [0002] The material of the existing falling film evaporator enters the upper head of the falling film evaporator at a saturated temperature state. Because the pressure of the liquid column decreases, saturated steam will flash out immediately, resulting in an increase in the pressure of the upper head, and the upper head and the vapor-liquid separation chamber The increase of the pressure difference causes the material to flow faster in the heating tube, and the heating tube is prone to serious erosion and wear. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the existing equipment and provide a brand new falling film evaporator pressure balance device. It specifically includes: the device is composed of a pressure balance pipe, a pipeline,...
