A tube shell horizontal liquid film flipping falling film absorption device using ω-shaped spring

Abstract

The invention discloses a tube shell horizontal liquid film flipping falling film absorbing device adopting an Ω-shaped spring, comprising a shell, a first separator, a liquid distribution plate, a falling film tube, a movable orifice plate, a fixed pulley, and a pulley line , suspending liquid receiving bucket, siphon pipe, liquid outlet pipe, gas inlet and the second partition; the liquid outlet pipe is connected to the bottom of the shell, the liquid distribution plate is connected between the first partition and the second partition, The film tubes are located under the liquid distribution plate, and the falling film tubes between two adjacent rows are arranged crosswise in the horizontal direction; each falling film tube is equipped with an Ω-shaped spring; the falling film tubes pass through the through hole of the movable orifice plate ; The Ω-shaped spring is connected to the first partition and the movable orifice; the pulley line is connected to the movable orifice and the suspended liquid-receiving barrel; the suspended liquid-receiving barrel is located in the liquid outlet pipe, and the siphon is connected to the suspended liquid-receiving barrel. The absorption device is equipped with an automatic reciprocating cleaning spring, which makes the outer spring of the falling film tube reciprocate automatically, enhances the disturbance of the liquid film, homogenizes the distribution of the liquid film, and has the function of automatic descaling.

Description

technical field [0001] The invention belongs to the technical field of absorption refrigeration, and in particular relates to a tube-shell horizontal liquid-film overturning falling-film absorption device using an Ω-shaped spring. Background technique [0002] Falling film absorbers are widely used in refrigeration and air conditioning, chemical and other industries, and the shell-and-tube spray falling film form is the main application form. In a common shell-and-tube spray falling film absorber, the absorption solution is sprayed from the small holes in the solution tray to the surface of the tube bundle passing through the cooling medium in the tube, and the absorption liquid flows from the upper tube bundle to the lower tube bundle in turn, and the liquid flows along the tube bundle. The wall flows down in the form of a liquid film, and the cooling medium passing through the tube is used to cool the liquid film. The tubes are filled with absorbed gas, and the gas is abso...

Problems solved by technology

[0005] In addition, during the flow process of the liquid film, due to the change of the physical properties of the outer wall of the falling film tube, the distribution of the liquid film is often uneven, and even the phenomenon of falling film trunk, channel flow or stream flow occurs, which will reduce the effectiveness of the liquid film. absorption area, resulting in a decrease in absorption rate

The impurities, flocs, and sediments adsorbed on the outer surface of the falling film tube for a long time will also affect the distribution of the liquid film, the absorption effect and the heat transfer effect with the cooling water.
