Treatment method and device for solid coking materials formed in fixed bed catalytic reaction

Abstract

The invention discloses a treatment method and device for solid coking materials formed in a fixed bed catalytic reaction. The device comprises a bottom plate, wherein a fixed table is fixedly arranged on the upper surface of the bottom plate; a fixed bed reactor body is fixedly arranged on the upper surface of the fixed table. Compared with the prior art, the treatment method has the advantages that a second motor is started, a driving shaft of the second motor drives a second rotating rod to rotate, the second rotating rod drives a worm wheel to rotate, the worm wheel drives a worm to rotate, the worm drives a third rotating rod to rotate, the third rotating rod drives a fourth rotating rod to rotate through two groups of transmission wheels and transmission belts, the fourth rotating rod drives stirring blades to rotate through a third connecting rod, and the stirring blades stir and collect waste liquid in a barrel, so that a fluorine-containing organic solvent fully reacts with carbon deposits and fine particles in the coking materials, and stirring of the waste liquid is completed; and therefore, the effect of subsequent waste liquid filtration is effectively improved, and the influence on the speed of subsequent waste liquid filtration due to precipitation of the carbon deposits and the fine particles in the waste liquid is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical cleaning, in particular to a method and device for treating solid coke formed in a fixed-bed catalytic reaction. Background technique [0002] In petrochemical, coal chemical and other related fields, a large number of catalytic reactions are involved, such as catalytic hydrogenation reaction, catalytic oxidation reaction, catalytic cracking reaction, etc. Among them, many catalytic reactions in continuous production have a particularly long production cycle, often reaching months or even years. For example, the catalytic reaction of catalyzed syngas to prepare dimethyl oxalate can be produced continuously and stably for 3 to 5 years; the catalytic reaction of catalyzed syngas to prepare dimethyl carbonate can be produced continuously and stably for more than 1 year; Catalyzed hydrogenation of esters to synthesize ethylene glycol, which can be continuously and stably catalyzed for more than 1.5 ...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the coking matter treatment devices in the prior art use machinery to directly remove the coking matter on the inner wall of the fixed bed reactor when dealing with the coking matter, which leads to poor cleaning effect of the coking matter on the inner wall of the fixed bed reactor and is easy to cause fixed Damage to the inner wall of the bed reactor;

[0004] 2. The coke treatment device in the prior art usually lacks the agitation of the coke and conventional solvents when processing the coke, resulting in a long treatment period and poor treatment effect for the coke, and at the same time, it is impossible to conveniently collect and process the coke After the waste liquid, the untreated waste liquid is easy to pollute the surrounding environment. Therefore, we propose a treatment method and device for the solid coke formed in the fixed bed catalytic reaction to solve the above problems
