Abstract

Способ термической переработки изношенных шин и резинотехнических изделий в среде рециркулирующих газов пиролиза в реакторе при температуре 200-500°С, с разделением продуктов пиролиза посредством аппарата разделения, при котором продукты пиролиза газообразные углеводороды от Cдо Сиз аппарата разделения подают в нижнюю часть реактора, а выходящие из топки реактора дымовые газы пропускают через теплообменник, расположенный внутри реактора, для нагрева рециркулируемых газов и перерабатываемого материала и при этом подают в бункер для нагрева находящегося в нем измельченного материала, а в качестве топлива для получения продуктов сгорания используют газообразные или жидкие углеводороды пиролиза, отличающийся тем, что давление рециркуляционных газов, подаваемых в нижнюю часть реактора, периодически изменяют во времени, а давление отвода продуктов пиролиза из верхней части реактора поддерживают постоянным, что обеспечивает периодическое изменение порового давления в каждой точке перерабатываемого материала при пиролизе в реакторе.A method for the thermal processing of worn tires and rubber products in a recycle pyrolysis gas atmosphere in a reactor at a temperature of 200-500 ° C, with the separation of the pyrolysis products by means of a separation apparatus, in which the pyrolysis products of gaseous hydrocarbons from Cdo Сiz separation apparatus are fed to the lower part of the reactor, and from the furnace of the reactor, flue gases are passed through a heat exchanger located inside the reactor to heat the recirculated gases and the processed material, and at the same time it is fed to the bunker for Eva of the crushed material contained in it, and gaseous or liquid pyrolysis hydrocarbons are used as fuel for the production of combustion products, characterized in that the pressure of the recirculation gases supplied to the lower part of the reactor is periodically changed in time, and the pressure of the removal of pyrolysis products from the upper part of the reactor keep constant, which provides a periodic change in pore pressure at each point of the processed material during pyrolysis in the reactor.

Claims
