Reactor for solid waste hydrothermal processing

Abstract

A reactor for solid waste hydrothermal processing comprises a body. In the reactor, a stirring blade is arranged. The upper part of the reactor is provided with a material inlet / outlet opening. The cover of the material inlet / outlet opening is provided with a safe valve and a pressure meter. The exterior of the reactor is provided with a jacket. The front cone and rear cone of the reactor is provided with a rolling ring and a corresponding riding wheel to fix the reactor. The rear cone is provided with a gear ring that is connected to the rolling ring. The lower head of the reactor is providedwith a thermometer interface. The bidirectional inner pipe heat conductive medium channel connection port in the bottom of the jacket is provided with a rotary joint. A driving device drives the gearring to rotate around an axis. The reactor can solve the problems that the solid wastes are hard to stir in solid waste hydrothermal processing, the leakage happens in the shaft seal of a reactor, and wastewater is generated.

Description

technical field [0001] The invention relates to a reactor, in particular to a reactor for hydrothermal treatment of solid waste. Background technique [0002] Reactor is a container used for physical or chemical reactions. It is used to meet the requirements of relevant processes for heating, evaporation, cooling and low-speed mixing functions. It is widely used in petroleum, chemical, rubber, pesticide, printing and dyeing, medicine, Food and other industries, used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the reaction kettle used to realize the hydrothermal treatment of organic solid waste is that high-temperature water vapor is directly passed into the material to realize the heating of the material. The stirring method of the material is that the stirring shaft is connected to the stirring paddle and inserted into the kettle, and the stirring is driven by the transmission device. The shaft moves to achieve the purpose of stirring, so it will face the problem of leakage at the shaft seal, and dynamic sealing is a worldwide problem, and for organic solid waste with high solid content, many fibers, and solid particles, a good shaft seal is more difficult accomplish

Bad shaft seals will lead to unenvironmental protection in the production process, and more importantly, there will be safety hazards in the production process

Many reactors are scrapped due to the failure of the shaft seal, and many production accidents are caused by the failure of the shaft seal

The hydrothermal treatment of solid waste in the prior art will generate a large amount of waste water, which is mixed with materials, which increases the difficulty of subsequent treatment of solid waste
