Organic silicon mechanical-free stirring continuous polymerization reactor

Abstract

The present invention discloses an organic silicon mechanical-free stirring continuous polymerization reactor. According to the organic silicon mechanical-free stirring continuous polymerization reactor, a liquid phase material inlet (7) and a solid phase material inlet (9) are symmetrically arranged on both sides of a gas phase outlet (8), wherein the gas phase outlet (8) is arranged on a middle position on the top of an upper cylinder (1) of a reactor body; a gas-liquid separator (10) arranged inside the upper cylinder (1) is opposite to the gas phase outlet (8); a side surface of the upper cylinder (1) is provided with an overflow port (6); the top of a diversion cylinder (2) arranged inside a lower cylinder (11) extends into the upper cylinder (1), and is communicated with the upper cylinder (1); the lower portion of the diversion cylinder (2) is internally communicated with the lower cylinder (11); a compressed gas inlet (4) is arranged on a middle position on the bottom of the lower cylinder (11); the compressed gas inlet (4) and the lower cylinder (11) are arranged on the same axis line; and a combination position of the compressed gas inlet (4) and the lower cylinder (11) is provided with a compressed gas distributor (5).

Description

Technical field [0001] The invention relates to a continuous polymerization reactor for organosilicon without mechanical stirring, in particular to a continuous reactor suitable for solid-liquid phase reaction in the synthesis of organosilicon polymer. Background technique [0002] Organosilicon materials are an important part of new chemical materials. They are polymers made by a combination of monomers or intermediates and modified organic groups with different functionalities through polycondensation. Its unique molecular structure gives it excellent and unique properties. With the expansion of human living space and the increasing demand for high-performance materials, silicone materials have become more closely related to people’s daily life, industrial and agricultural production, and high-tech development. They have been widely used in aerospace, electric power, construction engineering, textiles and clothing. Almost all industrial fields and high-tech fields such as petr...

Problems solved by technology

When producing in an indirect tank reactor, the stirring process will also increase the mutual friction between the catalyst particles and the agitator, resulting in fine catalyst particles that are difficult to separate from the product, and this part of fine catalyst particles not only increases the consumption of the catalyst, but also makes the The increase in production cost also has a greater impact on product quality such as appearance, viscosity, dielectric properties, etc.
