An anti-blocking structured packing

Abstract

The invention relates to anti-clogging structured packing which consists of a packing body. The packing body is formed by connecting and combining n packing units (n is greater than or equal to 2) along the extending directions of liquid collecting tanks; the extending directions of the liquid collecting tanks of all the packing units are parallel with one another and same; the outer edge of each upper wing and the outer edge of each lower wing of each packing unit are respectively connected with the outer edge of each upper wing and the outer edge of each lower wing of the adjacent packing unit in a same layer, and meanwhile, the outer edge of each upper wing of each packing unit is connected with the outer edge of each lower wing of the former packing unit, and the outer edge of each lower wing of each packing unit is connected with the outer edge of each upper wing of the next packing unit. Each packing unit comprises a pair of upper wings, a pair of lower wings and a liquid collecting groove. The size of each upper wing is as same as an elevation angle beta and the size of each lower wing is further as same as an elevation angle theta. The roots of the upper and lower wings on the same side of each liquid collecting tank are alternately connected with the edge of each liquid collecting tank. The section of each liquid collecting tank body is V-shaped. When the anti-clogging structured packing is horizontally placed, each V-shaped opening faces upward.

Description

technical field [0001] The invention is a structured packing used for rectification and absorption. The packing can be widely used in chemical tower equipment, and can effectively reduce the pressure drop of chemical towers. Chemical tower equipment. Background technique [0002] In the industrial application of tower equipment, it is often encountered: small pressure drop, small liquid phase flow, large gas phase flow, and easy scaling and clogging. The traditional plate tower generally has a large pressure drop, which is not suitable for this working condition; for the traditional packed tower: if it is suitable for the working conditions of small liquid volume and large volume, it should be equipped with a packing with a large specific surface area, and this packing has a precise structure and anti-blocking Poor capacity; in order to solve the clogging problem, only packing with small specific surface area can be used, and such packing is usually very low in efficiency. ...

Problems solved by technology

The traditional plate tower generally has a large pressure drop, which is not suitable for this working condition; for the traditional packed tower: if it is suitable for the working conditions of small liquid volume and large volume, it should be equipped with a packing with a large specific surface area, and the packing structure is precise and anti-blocking Poor capacity; in order to solve the clogging problem, only packing with small specific surface area can be used, and such packing is usually very low in efficiency. When the number of theoretical plates remains the same, the size of the required tower equipment will become larger, and the corresponding investment will increase

For example, the debenzene treatment of gas in the coking industry requires the use of benzene washing towers, which are mostly packed towers, which use washing oil to wash the gas generated by the coke oven. After long-term operation, the washing oil and gas will accumulate naphthalene, anthracene, fluorene and dust Substances that are easy to scale, such as asphalt and asphalt, will cause the clogging of the benzene washing tower, resulting in an increase in the pressure drop of the benzene washing tower. Finally, the benzene washing effect is not up to standard, and the packing needs to be cleaned frequently. Therefore, a high-efficiency anti-blocking structured packing is provided to meet This kind of working condition where the liquid phase flow rate is small, the gas phase flow rate is large, and it is easy to scale and block
