Continuous thermal desorption and cracking equipment with three-stage reactor system

Abstract

The invention discloses a continuous thermal desorption and cracking apparatus with a three-stage reaction furnace system. The thermal desorption and cracking apparatus comprises a first furnace body, a second furnace body and a third furnace body, wherein the first furnace body is provided with a first jacket, a first jacket inlet and a first jacket outlet; a plurality of first furnace body reactors, and first feed inlets and first discharge outlets thereof are arranged in the first jacket; the first feed inlets are arranged out of the first furnace body; a second jacket and a third jacket are respectively arranged in the second furnace body and the third furnace body; the second jacket is provided with a second jacket inlet and a second jacket outlet; the third jacket is provided with a third jacket inlet and a third jacket outlet; a second furnace body reactor, and a second feed inlet and a second discharge outlet corresponding to the second furnace body reactor are arranged in the second jacket; a third furnace body reactor, and a third feed inlet and a third discharge outlet corresponding to the third furnace body reactor are arranged in the third jacket; and the third discharge outlet is arranged out of the third furnace body. The continuous thermal desorption and cracking apparatus with the three-stage reaction furnace system is applicable to heating desorption, desorption and cracking, and reaction termination of a to-be-processed material.

Description

technical field [0001] The present invention relates to a three-stage reaction furnace system, in particular to a three-stage reaction furnace system for heating and desorption, desorption and cracking, and reaction termination operations on processed objects. The two parallel screw conveyors feed the material on average and react at the same time, and finally stop the reaction by cooling down. It is a continuous thermal desorption and cracking equipment with a three-stage reactor system. Background technique [0002] With the development of the global economy driving the vigorous development of the automobile industry, the rubber industry and the plastics industry, a large amount of discarded rubber and plastic solid waste is produced every year, especially waste tires. If they are not properly treated or recycled, not only It will cause a waste of resources, and will cause a nightmare impact on the environment, endangering the global land and environmental pollution. If t...

Problems solved by technology

However, in the past, there were several obstacles in the cracking of waste rubber, which could not be scaled up and the products were standardized. As a result, there was no standardized process for commercial production in this industry in the world. The main reason was that the secondary pollution of environmental protection could not be overcome, and the solid product carbon black could not be returned to rubber. Reuse in industrial systems, greatly reducing its recycling value

Therefore, the industry needs a method that can solve the problems of air pollution and environmental protection encountered in the past manufacturing process, the product standardization problem of unstable output of the manufacturing process, the industrial safety problem of gas explosion caused by unsafe manufacturing process, and the poor efficiency problem of the inability to increase the feeding amount.
