Method and device for treating solid coke formed in fixed bed catalytic reaction

Abstract

The invention discloses a method and a device for treating solid coke formed in a fixed bed catalytic reaction, comprising a bottom plate, a fixed table is fixed on the upper surface of the bottom plate, and a fixed bed reaction is fixed on the upper surface of the fixed table Compared with the prior art, when the second motor is turned on, the drive shaft of the second motor drives the second rotating rod to rotate, the second rotating rod drives the worm wheel to rotate, the worm wheel drives the worm to rotate, and the worm drives the third rotating rod to rotate, The third rotating rod drives the fourth rotating rod to rotate through the two sets of transmission wheels and the transmission belt, and the fourth rotating rod drives the stirring blade to rotate through the third connecting rod. The carbon deposits and fine particles in the liquid are fully reacted, thus completing the stirring of the waste liquid, which effectively improves the effect of the subsequent filtration of the waste liquid and avoids the deposition of carbon and fine particles in the waste liquid, which affects the subsequent filtration of the waste liquid. speed.

Description

technical field [0001] The invention relates to the technical field of chemical cleaning, in particular to a method and a 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 several months or even several years. For example, the catalytic reaction of catalyzing synthesis gas to prepare dimethyl oxalate can be continuously and stably produced for 3 to 5 years; the catalytic reaction of catalyzing synthesis gas to prepare dimethyl carbonate can be continuously and stably produced for more than 1 year; Catalytic hydrogenation of esters to synthesize ethylene glycol, which can be continuously and s...

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
