Description

Technical Field

[0001] The utility model relates to the field of stripping towers, in particular to a stripping tower used for processing methyltrimethoxysilane. Background Art

[0002] In the preparation process of methyltrimethoxysilane, the stripping tower is a key device. During the preparation process, methanol is heated into steam by a preheater and then enters the bottom of the stripping tower for reaction. At the bottom of this tower, a crude product of methyltrimethoxysilane can be obtained. The mixed gas produced at the top of the stripping tower enters the condenser for condensation separation and further treatment. For example, the existing stripping tower with a publication number of CN212688000U specifically discloses: a stripping tower body, an oil inlet pipe and an exhaust pipe are respectively provided at the upper end of the stripping tower body, an oil outlet and a steam inlet are respectively provided at the lower end of the stripping tower body, a packing layer and a liquid distributor are also included, the packing layer is arranged in the middle of the stripping tower body, the liquid distributor is fixed in the stripping tower body and is located above the packing layer, and the liquid distributor includes a cylinder with an open upper end and a plurality of branch pipes, and the upper ends of the plurality of branch pipes are connected to the inside of the cylinder. Since methanol is heated into steam by a preheater and then enters the bottom of a stripping tower for reaction, the steam rises in the stripping tower and reacts during the rising process. The steam rises quickly, resulting in insufficient time for the steam to react in the stripping tower, resulting in insufficient steam reaction and low steam utilization efficiency. For this reason, we propose a stripping tower for processing methyltrimethoxysilane. Utility Model Content
