Waste tire thermal cracking device

Abstract

The invention discloses a waste tire thermal cracking device which comprises a waste tire breaking device, a thermal cracking furnace, an oil gas recycling system, a smoke discharge system and a solid material recycling system, wherein the thermal cracking furnace is provided with a closed furnace body; a smoke-through chamber is arranged between the inner wall of the thermal cracking furnace and the furnace bed body and communicated with a combustion chamber; a rotary central spindle is arranged at the central part of the furnace bed body; multiple layers of material chambers are arranged in the furnace bed body from top to bottom; the rotary central spindle is provided with a stirring device extending into each material chamber; a furnace section is arranged between adjacent material chambers and comprises an inner blanking furnace section and an outer blanking furnace section; the broken waste tire is heated layer by layer by the closed thermal cracking furnace for thermal cracking; the generated oil gas is condensed and recycled, and the uncondensable combustible gas heats the thermal cracking furnace through the combustion chamber; and moreover, effective recycling of residual value and environment-friendly discharge are realized through the smoke discharge system and the solid material recycling system. Continuous production can be realized, the energy is saved while the environment is protected, and the problem of pollution of waste tire is solved.

Description

technical field [0001] The invention relates to a waste tire treatment technology, in particular to a waste tire pyrolysis device. Background technique [0002] With the rapid development of society today, the amount of waste tires is also increasing rapidly. The increasing amount of waste tires has become a global problem. Like the white pollution caused by waste foam plastics, some people call waste tires "black pollution". A large number of open-air storage of waste tires not only takes up space and pollutes the environment, but also breeds mosquitoes and infects diseases. With the rapid growth of the number of scrap tires and the seriousness of environmental pollution, the recycling and reuse of scrap tires has become a major environmental protection issue both at home and abroad in recent years. In my country, limited by the level of economic development, the treatment of waste tires and all waste rubber is still in the stage of simple recycling, which cannot fundame...

AI Technical Summary

Problems solved by technology

So far, the existing pyrolysis furnaces capable of continuous production focus on the separation of oil for the cracking of waste tires, and the quality of the finally obtained carbon black is not ideal, while the intermittent production pyrolysis furnaces can make the pyrolysis carbon The overall performance of black is close to the performance of N660, but because it cannot be produced continuously, there are still problems such as energy waste, environmental pollution and high cost.
