AI Technical Summary

Technical Problem

Existing waste tire pyrolysis equipment is prone to sudden temperature rises during the vacuuming process due to improper vacuum control, resulting in fine powder clogging the vacuum pipes, an imbalance between heat input and volatile matter release, and impacts pyrolysis efficiency and equipment safety.

Method used

A dynamic control system using inert gas to regulate vacuum and heating power monitors parameters inside the reactor through vacuum detectors and temperature sensors. Combined with the control unit, it adjusts the inert gas flow rate, vacuum pumping rate, and heating component power to achieve precise control of the pyrolysis reaction.

Benefits of technology

This effectively avoids overheating and vacuum fluctuations, improves the stability of the pyrolysis reaction and the yield of the target product, and reduces the generation of by-products.

Abstract

This utility model belongs to the field of tire processing technology, and in particular to a waste tire pyrolysis device. It includes a reactor for containing waste tires and carrying out the pyrolysis reaction; a heating component for providing the heat required for the tire pyrolysis; a vacuum system connected to the reactor via a vacuum pipe for evacuating the reactor and reducing the pressure inside; a vacuum detector for real-time monitoring of pressure parameters inside the reactor; and a temperature sensor for real-time monitoring of the temperature inside the reactor. It also includes a gas supply component for introducing inert gas into the reactor during the pyrolysis process to adjust the vacuum level; and a control unit for dynamically adjusting the operation of the gas supply component, vacuum system, and heating component based on the pressure parameters monitored by the vacuum detector and the temperature monitored by the temperature sensor. By introducing inert gas and regulating the pressure and temperature inside the reactor through the vacuum system, the device avoids excessively rapid reaction rates that could lead to temperature runaway, thus balancing the exothermic and heat dissipation of the pyrolysis reaction.
