Silicone monomer synthesis device with built-in separation assembly

A silicone monomer synthesis device with a built-in separation assembly, comprising:

• a device main body comprising a heat exchange assembly, a cylindrical reaction zone main cylinder, an inverted conical cylinder, and a gas inlet distributor, wherein the cylindrical reaction zone main cylinder, the inverted conical cylinder and the gas inlet distributor are sequentially connected to one another from top to bottom;
• the heat exchange assembly is installed inside the cylindrical reaction zone main cylinder, and a gas-solid two-phase flow composed of silicon particles and gas substances in the cylindrical reaction zone main cylinder exchanges heat with the heat exchange assembly;
• a separation assembly comprising a riser, a closed head, and an elbow pipe, wherein the closed head is arranged at a top of the cylindrical reaction zone main cylinder, an inlet communicating with the riser is provided on the closed head, the elbow pipe is connected to an outlet of the riser, and the elbow pipe is arranged in a tangential direction of the riser;
• a return assembly arranged between a circumferential wall located at a bottom of the closed head in the cylindrical reaction zone main cylinder and an inner wall of the cylindrical reaction zone main cylinder, wherein a return pipe of the return assembly communicates with a middle lower part of the cylindrical reaction zone main cylinder;
• and
• a gas outlet pipe arranged at the top of the cylindrical reaction zone main cylinder and located at a middle upper part of the separation assembly, wherein an outlet of the elbow pipe communicates with the gas outlet pipe, and an annular gap is reserved between the riser and an inner wall of the gas outlet pipe.
