Description

Technical Field

[0001] The utility model relates to a filter structure, in particular to a visual structure of an esterification tower filter. Background Art

[0002] Esterification is a type of organic chemical reaction, primarily involving the reaction of alcohols with carboxylic acids or inorganic oxygen-containing acids to form esters and water. It can be categorized into three types: reactions between carboxylic acids and alcohols, reactions between inorganic oxygen-containing acids and alcohols, and reactions between inorganic acids and alcohols. These reactions are generally very slow, so concentrated sulfuric acid is often used as a catalyst. Reactions between polycarboxylic acids and alcohols can produce a variety of esters, while reactions between strong inorganic acids and alcohols are generally faster. Esterification reactions are widely used in organic synthesis and other fields.

[0003] The Chinese invention patent with application number "202111000299.7" discloses an esterification tower structure for esterification reaction. The final product of the esterification tower leaves the esterification tower through the kettle liquid outlet and then enters the filter for filtration. During the filtration process, solid impurities in the filtrate will be deposited at the bottom of the filter cartridge and between the outer wall of the filter cartridge and the inner side of the shell, making it difficult to observe and it is impossible to determine whether backwashing or replacement and cleaning should be performed.

[0037] Working principle:

[0038] During use, the lower flange 22 made of transparent plastic material and the upper flange 14 made of stainless steel are connected by bolts 44. The inverted bolts 44 at the bottom are convenient for maintenance personnel to disassemble from the bottom. During normal use, since the sewage outlet 23 is closed on the outside, the staff can observe upward through the visual area 3 at the bottom of the transparent conical shell 2 to see whether there is blockage and sedimentation at the bottom of the filter basket 12, and then determine whether the filter basket 12 needs to be cleaned, replaced or backwashed. At the same time, if the outside of the filter basket 12 is a liquid inlet, the sedimentation above the connecting ring 31 can also be observed.
