Pretreatment process and device for industrial continuous waste tire cracking production

Abstract

The invention belongs to the technical field of waste cracking, and particularly relates to a pretreatment process and device for industrial continuous waste tire cracking production. The process canrealize the whole tire automatic feeding of waste tires; during the feeding, the whole tire cleaning, preheating and drying can be realized; the device consists of an impurity removal device, a cleaning device, a water sealing feeding device, a drying device and the like; impurities can be prevented from entering the subsequent cracking process along with the whole tire; meanwhile, the sealing ofthe feeding device is realized; the better connection with the cracking device can be realized; the weight of the sealing structure is reduced; meanwhile, the preheated whole tire enters the crackingprocess, so that the temperature difference can be reduced; the cracking efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of waste pyrolysis, and in particular relates to an industrial continuous waste tire pyrolysis pre-production process and device. Background technique [0002] At present, waste rubber is a waste flexible polymer material that is difficult to handle. Its molecular weight is relatively large, and it is difficult to effectively treat it by conventional treatment methods. It is generally treated by incineration combined with deep burial, but this treatment method will cause more damage to the environment. Therefore, how to deal with this part of the material process is an urgent problem to be solved. In the prior art, it is a good choice to process these materials through high-temperature cracking; after the cracking of waste rubber, gasoline, diesel oil, Products such as carbon black not only find a good solution for the disposal of waste tires produced in large quantities in modern society, but also provide n...

Problems solved by technology

[0002] At present, waste rubber is a waste flexible polymer material that is difficult to handle. Its molecular weight is relatively large, and it is difficult to effectively treat it by conventional treatment methods. It is generally treated by incineration combined with deep burial, but this treatment method will cause more damage to the environment. Therefore, how to deal with this part of the material process is an urgent problem to be solved. In the prior art, it is a good choice to process these materials through high-temperature cracking; after the cracking of waste rubber, gasoline, diesel oil, Products such as carbon black not only find a good solution for the disposal of waste tires produced in large quantities in modern society, but also provide new solutions for resource reduction and energy shortage improvement

[0003] However, at present, all the cracking of waste rubber is to first break the waste rubber into small pieces and then crack it. During the production process, additional tire crushing equipment needs to be prepared, which virtually increases the production cost and production process. Therefore, the whole tire is cracked into rubber The inevitable trend of pyrolysis, how to ensure the whole tire pyrolysis feed has become the first technical problem to be solved in the waste tire pyrolysis. The inventor of the present invention has proposed several solutions and obtained corresponding effects, but how to achieve better treatment effect and better adaptation to the pyrolysis process has become a technical problem that the inventors really want to solve
