Description

Continuous production device for recycling waste heat of dead catalyst

Technical Field

The utility model relates to the technical field of energy recovery, in particular to a continuous production device for recycling waste heat of a waste catalyst.

Background

The action of the catalyst in a chemical reaction is called catalysis. The solid catalyst is also referred to as a catalyst in industry, and the composition, chemical property and quality of the catalyst do not change before and after the reaction; the relation between the catalyst and the reaction system is just like the relation between a lock and a key, and the catalyst has high selectivity (or specificity), and does not have a catalytic effect on all chemical reactions, so that a large amount of waste materials can be generated when the catalyst is used, and the catalyst needs to be recycled through a special reaction kettle and a special process.

The reaction kettle is widely applied to the fields of petroleum, chemical industry, wet smelting, rubber, pesticides, dyes, medicines, food and the like, and is a pressure container for completing the technological processes of acidification, alkalization, nitration, sodium modification, hydrogenation, hydrocarbylation, polymerization, condensation and the like, such as a reactor, a reaction pot, a decomposition pot, a polymerization kettle and the like; materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based (hastelloy, monel, and Kang Nie) alloys, and other composite materials.

In the process, the continuous production of the reaction kettle cannot be ensured due to intermittent operation, so that the yield is low. Such as: in the process of recycling the waste catalyst, firstly, ground waste agent is added into a kettle, then solvents such as water and the like are added for mixing and stirring, then the temperature of the reaction kettle is raised, after the reaction temperature is reached, materials in the kettle start to continuously react, the reaction is subjected to cooling and discharging for several hours, in the whole process, the intermittent operation time is long, and the reaction kettle needs to continuously raise the temperature, lower the temperature, pressurize and decompress, and the materials of the reaction kettle are easy to fatigue and crack, leak and even explode, thereby influencing the safety of equipment, having potential safety hazards, and meanwhile, when the materials are discharged, a large amount of heat gas containing impurities needs to be cooled, and the common practice in the prior art is to directly enter the next procedure after cooling the materials by using cooling water, waste heat is generated, and the production cost is high.
