Description

Technical Field

[0001] The utility model belongs to the field of waste rubber and plastic thermal cracking equipment, in particular to a hanging plate type waste rubber and plastic thermal cracking equipment. Background Art

[0002] With the rapid development of my country's economy and the general improvement of people's living standards, cars have gradually entered people's daily lives, resulting in a large number of waste tires. Data show that in 2006, my country's tire production reached 280 million, ranking first in the world. The waste tires produced that year also reached 140 million, about 3.6 million tons. It is estimated that by 2010, the amount of waste tires produced in my country will reach more than 200 million. The accumulation of a large number of waste tires not only occupies land, but also easily causes fires and causes environmental pollution. Recycling waste tires can not only alleviate their pressure on the environment and reduce pollution, but also achieve effective recycling of resources.

[0003] Waste tire pyrolysis refers to an irreversible thermochemical reaction in which organic matter in waste tires is cracked by high temperature in an oxygen-free or oxygen-deficient atmosphere, volatile products are released and solid coke is formed. Gas, liquid and solid products can be formed during the incomplete thermal degradation process. This method can completely crack waste tires into useful products such as pyrolysis oil, pyrolysis carbon black and pyrolysis non-condensable gas.

[0004] The waste tire pyrolysis continuous equipment on the market is divided into two categories: continuous external pyrolysis equipment and continuous internal rotation pyrolysis equipment:

[0005] The first type is the external rotation thermal cracking equipment, whose working principle is that the kettle body rotates itself, and the feed end and the discharge end of the kettle body need to be set up with dynamic and static coordination. The advantage is that the structure is relatively simple and the failure rate is low. The disadvantage is that if the dynamic and static coordination at both ends is not well sealed, it is easy to cause leakage of high-temperature oil vapor, which creates safety hazards.

[0006] The second type is the internal rotation thermal cracking equipment, whose working principle is that the kettle body itself does not rotate, but the spiral shaft set in the kettle body rotates. The advantages are that there is no static and dynamic coordination between the feeding and discharging ends of the kettle body, which will not cause leakage of high-temperature oil vapor. Secondly, due to the internal spiral operation, the kettle body will not coke during long-term operation. The disadvantage is that the kettle body runs at high temperature, the internal spiral design structure is complex, and the linear expansion caused by high temperature can easily cause deformation of the running parts.

[0007] However, the two types of thermal cracking equipment currently have both environmental and safety issues such as leakage of high-temperature oil vapor and complex problems with the internal spiral design structure, which affects the thermal cracking efficiency. Utility Model Content
