Description

(sit) REACTOR

The invention relates to the construction of chemical reactors and can be used to conduct heterogeneous catalytic reactions in a gas, liquid - system. solid. A known liquid-solid gas system reactor, vertical q contents, an inner body, a conical bottom, a circulation pipe coaxially mounted in the body, and baffles, and the closest to the invention in terms of the effect achieved is a reactor for carrying out heterogeneous catalytic reactions, containing a vertical cylindrical body with a conical bottom and an expanded upper separation hour; a circulation pipe with a heat exchange jacket, coaxially mounted in the housing, a vertical battening lane town, razmatsennuyu outside the circulation pipe and separating the body from the liquid channel output, and the input and output connections} reagents. A disadvantage of the known reactors is the low efficiency of the contacting processes. . The aim of the invention is to intensify the processes by mixing and creating a gas cushion. The goal is achieved by the fact that the reactor contains a vertical cylindrical body with a conical bottom and an extended upper separation part, a circulating pipe with a heat-exchange jacket coaxially installed in the case, a rotted pejurodka located outside the circulation pipe and separating from the building; and branch pipes of input and output of reagents, is supplied with two coaxially installed -.

Inside the circulating tube, the gas supply pipes and the baffle ring mounted on the internal gas supply pipe under the outlet end of the external gas supply pipe will accept the lower end of the circulation pipe between the output ends of the gas supply pipe.

The bottom can be made with variable taper.

The drawing shows the proposed reactor, a longitudinal section.

The reactor for carrying out heterogeneous catalytic reactions contains a vertical cylindrical body 1 with a conical bottom 2 and an expanded upper separation part 3. A circulation pipe f with a heat exchange jacket 5 coaxially installed in the case, a vertical partition 6 placed outside the circulation pipe and a channel extending from the case 7 for the withdrawal of the liquid, the nozzles 8 of the input and output of the reactants, two gas-supplying pipes 15 and 16 coaxially installed inside the circulation pipe k and the reflection ring 17, are closed the captive on the inner gas supply pipe 16 under the outlet end of the outer gas supply pipe 15

The lower end of the circulation pipe 4 is located between the outlet ends of the gas supplying pipes 15. and 16, and the bottom 2 is made with a variable taper

The reactor operates as follows.

Through pipe 11, the reactor is poured liquid source product. Then, gaseous reactant is supplied through pipes 15 and 16, which creates a continuous circulation of the liquid phase between the pipes 15 and the septum 6. Next, a solid phase, a catalyst, is introduced through pipe 10 and the liquid product continues to be continuously introduced through pipe 11. The reaction products are discharged through connection 13 1, free from catalyst ;.

The temperature in the reactor is maintained by means of a heat transfer medium supplied to the jacket 5. The peaKtopa is completely emptied through the pipe 14.

The economic effect of the use of the proposed reactor can be

determined at the start-up of the pilot plant and can be calculated based on the cost of additionally released products by increasing the degree of use of the catalyst,

preventing reactor shutdowns to remove the packed catalyst.
