Abstract

The invention discloses equipment for preheating and cracking waste tires on the basis of solar energy. The equipment comprises a heat collecting device, a feeding preheating device, a cracking device, an oil-gas separation storage device, a solid product recovery device and an automatic control system. The devices are connected with one another, and the heat collecting device in the equipment forpreheating and cracking waste tires on the basis of solar energy can absorb solar energy to provide necessary temperature for cracking the waste tires; a disc type heat collector in the heat collecting device can collect sunlight. According to the equipment, the defects of strong dependence of traditional pyrolysis modes on fossil fuels or electricity and insufficient heat supply, caused by the factors such as weather and different time periods, of sunlight in the prior art are overcome, the economic benefit is increased, and carbon emission is reduced. An automatic tracking device of the disc type heat collector can automatically adjust the direction and angle of a reflecting plate along with the movement of the sun to provide stable solar radiation for a receiver in order to ensure sufficient heat energy output and solve the problem of heat source shortage caused by seasonal and climatic factors.

Description

technical field [0001] The invention relates to a device for reprocessing waste tires, in particular to equipment for preheating and cracking waste tires based on solar energy. Background technique [0002] In 2018, the world's tire production is expected to exceed 2.2 billion. By 2020, the annual tire demand will exceed 2.5 billion, with a compound annual growth rate of 3% - expected to be around 5%. At the same time, the number of waste tires will continue to increase. Waste tires are considered to be an increasingly serious environmental and economic problem, so how to deal with these waste tires reasonably and efficiently has increasingly become the focus of widespread attention in various countries. The methods of comprehensive utilization of waste tires in my country mainly include retreading and remanufacturing of waste tires, production of reclaimed rubber, rubber powder and thermal cracking, etc., but the utilization efficiency and economy of the first three treatme...
