Embodiment approach 1

[0025] This embodiment provides an organosilicon fluidized bed reactor, such as Figure 2 to 5 As shown, the reactor is mainly composed of an upper head 1, a first cylinder 2, a second cylinder 3, a third cylinder 4, and a lower head 5 arranged in sequence from top to bottom. The product gas outlet 11 and the solid material inlet 12 are provided; the diameters of the first cylinder 2, the second cylinder 3 and the third cylinder 4 increase in sequence, and the cylinder diameter of the second cylinder 3 is the same as that of the first cylinder 2. 1.2 times the cylinder diameter, the cylinder diameter of the third cylinder 4 is 1.5 times the cylinder diameter of the first cylinder 2; the junction of the first cylinder 2 and the second cylinder 3 and the second cylinder 3 and the third cylinder The joints of the cylinder 4 are all concave structures 17.

[0026] A first heat exchange tube 8 arranged in an S-shaped fold is fixed in the first cylinder 2 through three grids 20 arrang...

Embodiment approach 2

[0030] This embodiment is a further improvement of Embodiment 1. The main improvement is that, in Embodiment 1, the diameters of the first heat exchange tube 8, the second heat exchange tube 9 and the third heat exchange tube 10 are the same, and In the first cylinder 2, the second cylinder 3, and the third cylinder 4, the distances between the pipes of the three heat exchange tubes are equal, and since the reaction in the third cylinder 4 in the reactor is the most intense, the more Up to the second cylinder 3 and the first cylinder 2, the intensity of the reaction gradually decreases. If the diameters of the three heat exchange tubes in the three cylinders are the same and the distance between the tubes is equal, the heat exchange efficiency is basically the same , And the heat generated by the reaction in the three cylinders decreases at once, so the design is not conducive to reasonable heat dissipation. In this embodiment, the reasonable arrangement of the three heat excha...

Embodiment approach 3

[0036] This embodiment is a further improvement of the second embodiment. The main improvement is that in the second embodiment, the higher the pressure of the silicone fluidized bed reactor, the lower the pressure and the lower the temperature, and the higher the reaction effect, the higher Poor; In order to effectively improve the above-mentioned situation, in this embodiment, four openings are provided in a circle at the two concave structures 17 and the gas booster nozzle 18 inclined to the upper part of the inside of the cylinder is used for injection and bottom high temperature The gas inlet 15 is the same high-temperature gas. In this embodiment, the two-stage gas pressurization nozzle 18 is used to pressurize the gas to ensure that the reactants continue to rise, so that the upper cylinder (the second cylinder 3 and the first cylinder 2) The reactant can also react completely under sufficient conditions; the gas inlet of the gas booster nozzle 18 can be adjusted in real ...

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...
