Organosilicone fluidized bed reactor

Abstract

The invention relates to the field of fluidized bed reactors, and discloses an organosilicone fluidized bed reactor. The organosilicone fluidized bed reactor comprises an upper seal head (1), a firstdrum body (2), a second drum body (3), a third drum body (4) and a lower seal head (5) which are successively arranged from top to bottom, wherein the drum diameters of three drum bodies are successively increased from top to bottom; the interiors of three drum bodies are respectively provided with a first heat exchange pipe (8), a second heat exchange pipe (9) and a third heat exchange pipe (10)which are independently arranged and respectively provided with a heat-conducting oil inlet (6) and a heat-conducting oil outlet (7); a finished product gas outlet (11) and a solid material inlet (12)are arranged on the upper seal head; a gas distributor (13) is arranged in the lower seal head; the bottom part of the lower seal head is provided with a reactant outlet (14) and a high-temperature gas inlet (15); and at least one chloromethane main pipe (16) is arranged at the junction of the third drum body and the lower seal head. According to the invention, the drum body of a reactor is designed into three parts with drum diameters successively increased from top to bottom, so a reaction is promoted to be easily performed, and heat dissipation is easily accelerated.

Description

Technical field [0001] The invention relates to the field of fluidized bed reactors, in particular to an organosilicon fluidized bed reactor. Background technique [0002] The organosilicon fluidized bed reactor is a type of reactor that reacts silicon powder, copper powder and methyl chloride gas inside it to finally generate methyl monomer. The reaction requires a high temperature of about 300° to proceed, and a lot of heat is generated during the reaction. The silicon powder and copper powder materials enter the bottom of the reactor from the upper feed port, the methyl chloride gas enters the reactor from the methyl chloride header on the bottom side, and the high temperature gas enters the reactor from the bottom inlet. The high-temperature and high-pressure gas at the bottom blows the material upward from the bottom, and emits heat while reacting, and the heat is carried out by the heat transfer oil flowing in the pipeline in the reactor. The solids produced by the reacti...

Problems solved by technology

In the reactor with this structure, since the cylinder body 2 is long and the thickness is equal up and down, the distance between the folded heat exchange tubes 8 is also equal up and down, and the bottom of the cylinder body 2 is the place where the reaction is the most intense. The high-temperature and high-pressure gas entering cannot effectively push the reactants upward continuously, resulting in the inability of the reactants in the middle and upper part of the cylinder 2 to fully react
