Tube-shell horizontal liquid film turnover falling-film absorption device using omega-shaped springs

Abstract

The invention discloses a tube-shell horizontal liquid film turnover falling-film absorption device using omega-shaped springs. The device comprises a casing, a first partition plate, a liquid distribution disc, falling-film tubes, a movable hole plate, a fixed pulley, a pulley line, a suspension liquid collection barrel, a siphon, a liquid outlet tube, an air inlet and a second partition plate. The liquid outlet tube is connected with the bottom end of the casing, the liquid distribution disc is connected between the first partition plate and the second partition plate, the falling-film tubes are disposed below the liquid distribution disc, and the falling-film tubes between the two adjacent rows are arranged crosswise horizontally. An omega-shaped spring is sleeved on each falling-film tube. The falling-film tubes penetrate through holes of the movable hole plate. The omega-shaped springs are connected with the first partition plate and the movable hole plate. The pulley line is connected with the movable hole plate and the suspension liquid collection barrel, the suspension liquid collection barrel is disposed in the liquid outlet tube, and the siphon is connected into the suspension liquid collection barrel. According to the device, the springs are cleaned automatically in a reciprocated mode, the liquid film disturbance is enhanced, the liquid film distribution is uniformized, and the automatic de-scaling function is provided.

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.
