Catalytic cracking moving bed reactor with high-value utilization of waste tire

Abstract

The invention relates to a catalytic cracking moving bed reactor with high-value utilization of a waste tire. The reactor comprises an outer body and a built-in variable speed reaction chamber, wherein any one of the two ends of the built-in variable speed reaction chamber is connected with a link rotating mechanism; an air mixing chamber is formed between the built-in variable speed reaction chamber and the outer body; the bottom of the air mixing chamber is provided with three hot air flow inlets which are uniformly distributed; the two sides at the top end of the air mixing chamber are provided with hot air flow outlets; the inner wall of the built-in variable speed reaction chamber is provided with guide fins; one end of the built-in variable speed reaction chamber is connected with an air-lock continuous feeder, and the other end of the built-in variable speed reaction chamber is connected with an air-lock pushing discharger; discharging guide fins and a carbon black collecting hopper and a backstop fin which rotate along with a barrel are arranged in the axial end of a discharge port; an oil gas outlet and the discharge port are formed outside the barrel of the air-lock pushing continuous discharger and have a symmetric structure in the vertical direction; a non-balance cartridge seal is adjacent to the built-in variable speed reaction chamber, the air mixing chamber, the feeder and the discharger respectively; and a heat-insulating inner liner is connected with the two axial ends of the variable speed reaction chamber in symmetric distribution.

Description

A catalytic cracking moving bed reactor for high value utilization of waste tires technical field The invention relates to the field of waste tires, in particular to a catalytic cracking moving bed reactor for treating waste tires. Background technique With the development of modern economy and automobile industry, there are more and more waste tires. At present, my country's waste tires are mainly used to produce reclaimed rubber and rubber powder. The production of reclaimed rubber has high energy consumption and heavy pollution, and is gradually being eliminated worldwide; the market application of rubber powder products in my country has not yet been widely promoted, and the production capacity is limited. In addition, tire products can no longer be used to produce tire products after 2-3 times of reuse. "Catalytic cracking" technology is the ultimate way to recycle waste tires, and it is also an important method for the harmless and resourceful treatment of waste ti...

Problems solved by technology

The pyrolysis of waste tires is carried out in pyrolysis reactors. There are a small number of waste tire pyrolysis reaction devices in developed countries such as Europe and the United States. The technical process design is complicated, the equipment structure is huge, and the operating cost is high. Only the government's environmental protection and economic policy support However, due to the low technical content and small processing scale of the traditional thermal cracking reactors that are common in China, they cannot produce good economic benefits, let alone carry out large-scale industrialization. There are insurmountable technical problems in varying degrees in raw materials and continuous slag discharge. The safety factor and service life of the equipment are reduced, the environmental pollution is serious, and the cost is increased. At the same time, it also affects the quality and cracking efficiency of oil products and carbon black.
