Problems solved by technology

[0005] The problem with all these processes at the pilot plant or production scale is that at the end of the process, the sorbent or filter aid needs to be manually removed from the filter housing, exposing workers (especially In the case of the use of organic substances, volatile solvents) and also imply an ergonomically unfavorable activity (which is a heavy burden on the worker and can also cause long-term health damage)

Embodiment Construction

[0042] in particular, figure 1 Shown is a bag filter element with a tubular side wall (2) extending upwards at a constant radius from a circular base part (1), characterized by two conveyor belts (3), each a conveyor belt extending from one side of the side wall (2) via the base portion (1) to the opposite side of the outer side wall of the bag and intersecting at the center of the base portion, the ends of said conveyor belt being shaped to form A conveyor ring (4), said conveyor belt is also connected at the upper edge of the filter element by a sealing strip (5) extending over the entire edge on the outside surface of the side part. The conveyor loop (4) is designed such that the conveyor belt (3) is folded towards the outside over the edge of the filter element and the two conveyor loop arms thus formed are attached in contact with each other.

[0043] figure 2 The depicted device comprises a filter housing (11) with a housing cover (17), a bowl-shaped base plate (14) a...

Abstract

The invention relates to a bag-like filter element (20) and to a device containing the filter element for adsorption filtration, precoat filtration or adsorption chromatography of liquids and to the use of said device for the separation of mixtures of substances , especially for purification of reaction products.

Description

technical field [0001] The invention relates to a bag-shaped filter element for adsorption filtration of liquids, for precoat filtration or for adsorption chromatography, as well as to a device for receiving the filter element, and also to the use of the device for separating mixtures of substances and especially for Use for purification of reaction products. Background technique [0002] It is known to purify the reaction product by adsorption filtration, filter adsorption, precoat filtration or adsorption chromatography. [0003] According to A. Wust, Rompp online, Georg Thieme Verlag KG, Stuttgart, 2016, adsorption by filtration refers to the process that if the mixture to be separated is dissolved in a suitable solvent and the solvent is filtered through the adsorbent Such that the adsorbent leaves only one component, it is then possible to separate two chemically different substances from each other due to their different adsorption capacities. Filtration adsorption d...
