Gas-oil mixed pyrolysis furnace

Abstract

The invention relates to the scrap rubber cracking field, in particular to a gas-oil mixed cracking furnace for the scrap rubber, solving the problems during cracking in the prior art for the scrap rubber by a thermal cracking technology, such as insufficient and uneven heating, poor cooling effect for a lysate and so on. The gas-oil mixed cracking furnace comprises a cracking bin and a cooling bin, wherein the cracking bin is formed by a material cracking chamber and a combusting and heating chamber; a cracking gas internal circulation outlet pipe is arranged above the material cracking chamber, and is connected with an air inlet of a centrifugal fan; an air outlet of the centrifugal fan is connected with an air return pipe; the lower end of the air return pipe is connected with an air return hole; the bottom of the combusting and heating chamber is provided with a combustion chamber and a combustor; and a dry ice cooling jet orifice is arranged in the cooling bin. The gas-oil mixed cracking furnace for the scrap rubber adopts a cracking gas internal circulation heating system and a heating chamber externally enclosed heating mode to further heat a cracking material sufficiently and evenly without a dead area, so that the scrap rubber can be cracked more sufficiently and more quickly; the dry ice can quickly cool a cracked product with good effect; and the gas-oil mixed cracking furnace has the advantages of integrally sealed equipment, high energy utilization and high performance of the cracked product.

Description

technical field [0001] The invention relates to the field of waste rubber cracking, in particular to a gas-oil mixed cracking furnace for waste rubber. Background technique [0002] With the rapid development of the automobile industry and the mass production of waste tires, the recycling industry has also made great progress. In the existing technology, the commonly adopted method is to retread tires and produce reclaimed rubber. The former is limited by the number of retreads and will eventually pollute the environment, while the latter has the disadvantages of long production process, high energy consumption and serious environmental pollution. , High labor intensity and low profit. With the continuous development of technology in this field, people have found that recycling waste rubber can save a large amount of crude oil consumed in the production of synthetic rubber, that is, waste rubber is thermally cracked under the action of a catalyst to obtain 45% fuel oil, 35%...
