Embodiment 1

[0083] Tire fragments with a particle size of 5 mm to 30 mm (see Table 1 for tire analysis data) are continuously fed into the rotary bed pyrolysis furnace at a rate of 2 t / h, and are directly contacted with non-condensable gas at a temperature of about 550 ° C to exchange heat and undergo pyrolysis. When the tire reaches 520°C, tar vapor and non-condensable gas are generated, and solid carbon black and iron wire are obtained. The solid product obtained at a temperature of about 480°C enters the cooling system for cooling to recover heat, and the cooled solid product is sent to the storage bin. The temperature of the generated oil gas and non-condensable gas for heating is about 500°C after mixing, and is drawn out of the rotary bed pyrolysis furnace through multiple oil and gas outlets on the top of the rotary bed pyrolysis furnace. The oil and gas outlet positions are different, and the outlet oil gas temperature has a certain difference. The oil and gas from each oil and gas...

Abstract

The invention provides a waste tire pyrolysis system and a pyrolysis method. The waste tire pyrolysis system comprises a spinning device, a crushing device, a rotating bed pyrolysis furnace, a pyrolysis solid processing device, a cooling and purification device, an oil storage tank and a regenerative rotary heat exchanger; the rotating bed pyrolysis furnace is suitable for performing pyrolysis treatment on pyrolysis raw materials; a rotatable feeding plate for containing the pyrolysis raw materials is arranged in the rotating bed pyrolysis furnace, and divides the rotating bed pyrolysis furnace into a pyrolysis chamber located above the feeding plate and a heating chamber located under the same, wherein the feeding plate is provided with multiple through holes for communicating the pyrolysis chamber with the heating chamber; the regenerative rotary heat exchanger is respectively connected with the cooling and purification device and a hot gas inlet of the rotating bed pyrolysis furnace, and is used for heating non-condensable gas and then performing pyrolysis treatment. Therefore, the waste tire pyrolysis system provided by embodiments of the invention can be used for performing pyrolysis on waste tires effectively.

Description

technical field [0001] The invention belongs to the field of pyrolysis, in particular, the invention relates to a waste tire pyrolysis system and a pyrolysis method. Background technique [0002] Waste tires are difficult to biodegrade. Long-term storage in the open air not only takes up a lot of land, but also produces toxic and harmful gases, seriously polluting the environment. At present, the comprehensive utilization methods of waste tires mainly include retreading, reclaimed rubber, rubber powder, thermal energy utilization and pyrolysis, among which pyrolysis has attracted widespread attention due to its high resource recovery rate and low secondary pollution. [0003] Pyrolysis technology is to heat organic matter to 450-1000°C in the absence of oxygen or oxygen, so that solid carbonaceous matter (tires, biomass, garbage, waste tires, waste organic matter, organic sludge, etc.) Gas (pyrolysis gas), fuel oil and pyrolysis carbon are the main storage energy sources. ...
