Problems solved by technology

For example: in the traditional column, the supporting angle steel and the liquid receiving plate are welded, which is easily deformed during the welding process, making the entire column plate uneven, resulting in uneven thickness of the liquid layer, which affects the mass transfer between the gas and liquid phases Effect; in the traditional tower equipment, the downcomer plate is welded on the inner wall of the tower, which makes the area between the downcomer plate and the inner wall of the tower difficult to maintain and clean; in the traditional tower equipment, the liquid rec

Embodiment

[0019] Implementation example: adopt the novel column device announced by the present invention to separate the vinyl chloride system, and the feed flow rate is 45m 3 / h, wherein vinyl chloride accounts for 90% (mass percentage, the same below), dichloroethane accounts for 3%, acetylene accounts for 2%, water accounts for 1%, and the rest are trace impurities. The tower height is 25m, the tower diameter is 2m, 40 trays, and the plate spacing is 400mm. After being treated by the novel tower equipment disclosed by the invention, the top vinyl chloride accounts for 85%, acetylene accounts for 14%, and the others are light impurities. At the bottom of the tower, vinyl chloride accounts for 95%, ethylene dichloride accounts for 3.2%, water accounts for 1.2%, and the rest are heavy impurities, which achieves a good separation effect. It takes about 2 to 3 days to complete the installation of the traditional tower with the same size, but the new tower equipment disclosed by the pres...

Abstract

The invention discloses novel tower equipment and relates to a mass transfer process in industrial processes, belonging to the field of gas-liquid mass transfer devices. In the tower equipment, supporting angle iron and a liquid receiving disk are manufactured into a piece, thus the processing efficiency and the levelness of a tower plate can be improved; a liquid downcomer plate and the liquid receiving disk are manufactured to be detachable so as to be convenient to assemble, maintain and clean the equipment; and a safety plate is arranged above each manhole, i.e. below a lowest tower plate on the part of the tower body for protecting workers while mounting and maintaining. The equipment can be used for the mass transfer process in industries of chemical industry, petrifaction, light industry, metallurgy, and the like and has the characteristics of simple structure, low manufacturing cost, obvious economic benefit, and the like.

Description

technical field [0001] The invention relates to a novel tower device, which belongs to the field of mass transfer devices in chemical engineering and other industrial processes. Background technique [0002] The mass transfer equipment used in chemical industry, petroleum, light industry, metallurgy and other industrial production mainly includes plate tower and packed tower. The plate tower has good anti-clogging performance, easy cleaning, and low cost for large towers. It has a wide range of applications, but there are some problems in practical applications, which hinder the further development of tray towers. For example: in the traditional column, the supporting angle steel and the liquid receiving plate are welded, which is easily deformed during the welding process, making the entire column plate uneven, resulting in uneven thickness of the liquid layer, which affects the mass transfer between the gas and liquid phases Effect; in the traditional tower equipment, the...
