Embodiment Construction

[0027] The present invention is described in detail below in conjunction with accompanying drawing;

[0028] The invention discloses a device for realizing catalytic cracking oil and gas co-production of waste rubber powder in a fluidized state. This device is divided into an external heating system, an internal fluidization system, and an upper feeding system. The internal fluidization system is further divided into an upper part. The cracking sleeve device and the lower air preheating device, the upper cracking sleeve device and the lower gas preheating cylinder are seamlessly connected by bolts, and there is a detachable air pressure uniform distribution plate at the bottom of the upper cracking sleeve device, Different forms of air pressure distribution plates can be replaced to achieve different fluidization states. When preparing cracked rubber powder for oil and gas co-production technology, use the external heating system to heat the internal fluidization system to the...

Abstract

The invention provides a device and a method for realizing catalytic cracking oil and gas cogeneration in a fluidization state by waste rubber powder. Rubber powder and a catalyst are sufficiently stirred; when a bed body is heated to required temperature by a heating system, a charging valve is opened, and catalytic cracking of the rubber powder is realized. Current reaction devices for cracking are rotary kilns and general resistance type heating furnaces, so that the cracking reaction efficiency is low and the reaction is incomplete. A fluidization technique provided by the invention references the fluidized-bed reaction principle; fluidizing gas enters from the lower part, a cracking material is enabled to be in the fluidization state, and the cracking reaction speed is incased, so that the cracking reaction is more sufficient. The other innovation of the device is that an intermediate air pressure uniform distribution plate can be detached for replacement; one cracking sleeve can be suitable for different cracking materials. The device can achieve the aim of cracking at constant temperature, i.e., the materials and the catalyst are added into the device for cracking after the cracking sleeve is heated to designated temperature, so that the quality of an obtained cracking oil product is improved.

Description

technical field [0001] The invention discloses a device and method for realizing catalytic cracking oil and gas coproduction of waste rubber powder in a fluidized state. Background technique [0002] The development of the transportation industry has brought great convenience to people's lives, and at the same time it has also brought about a continuous increase in the amount of waste rubber. The existence of waste tires not only takes up a lot of land, but also seriously threatens the environment. The accumulation of waste rubber provides a place for mosquitoes to breed, and fires caused by waste rubber fires also occur from time to time. At the same time, a large amount of carcinogens and polycyclic aromatic hydrocarbons will be produced during the combustion of rubber, resulting in serious environmental pollution. [0003] In recent years, countries have made some progress in the pyrolysis of waste rubber. There are many methods for pyrolysis of waste rubber, such as vac...
