Scrap tires can be refined!

The principle of waste tire oil refining is the popular thermal cracking technology, which splits the tire into oil and gas, and then condenses it into tire oil through condensation and air cooling. At this time, the tire oil is also called crude oil and primary oil, and a small amount of water vapor will enter the tire oil. Among them, non-condensable combustible gas can be burned in the furnace, and some residual oil, also called heavy oil, will remain in the sub-barrel, which can be remelted in the furnace with high noise and certain danger, or directly mixed with tire oil for sale (not recommended).

It is also legal to refine waste tires. First of all, the equipment is legal. According to the national standard GB/T 32662-20 16, waste tire refining equipment is divided into continuous and intermittent waste rubber and waste plastic cracking and refueling complete sets of production equipment. So the legitimacy of this equipment is beyond doubt. Secondly, the Ministry of Industry and Information Technology issued corresponding guidelines on the utilization of waste tire resources to guide the healthy and orderly development of the industry.

Let's take a look at waste tires and their various ways of resource utilization:

Waste tires are mainly composed of rubber and belong to insoluble or refractory polymer elastic materials. It takes hundreds of years for their macromolecules to decompose to a level that does not affect the growth of plants in the soil. More and more waste tires are piled up in the open air for a long time, which not only occupies a lot of land, but also easily breeds mosquito-borne diseases (dengue fever, etc.). ), seriously deteriorating the natural environment, destroying plant vegetation and seriously endangering the earth's ecological environment. It may also cause fires and threaten people's lives and property, which is called "black pollution". In some areas, waste tires are used as fuel, and serious pollution makes nothing grow around them. Solid waste disposal methods such as landfill and combustion are not applicable to waste tires.

At present, the recycling methods of waste tires are mainly direct utilization, such as: tire retreading; Processing and utilization after crushing, such as producing rubber powder and reclaimed rubber; Utilization of heat energy, such as direct incineration for power generation and thermal cracking. Among them, thermal cracking is a technology that completely decomposes waste tires into various available resources. High value-added pyrolysis gas, pyrolysis oil, pyrolysis carbon and steel wire can be obtained after pyrolysis of waste tires, which is a popular method for recycling waste tires at present and is considered as one of the most economical and best ways to treat waste tires.

The retreading of used tires is internationally recognized as the first choice to reduce, reuse and recycle tires.

Reclaimed rubber has become the third indispensable rubber resource in china rubber industry after natural rubber and synthetic rubber.

The direct application of rubber powder is an internationally recognized environmentally friendly and resource-friendly method for the harmless processing and utilization of waste tires.

Thermal cracking is the last link in the recycling of waste tires, and it is an important means to "eat and squeeze" waste tires.
