Problems solved by technology

To alleviate this problem, it is ideal to use thermal pyrolysis at present. The traditional method is to put the waste tire block into a pyrolysis furnace for dry distillation and pyrolysis to recover fuel oil, combustible gas and carbon black. Pull out the ring-shaped steel wire in the waste tire, then cut the waste tire into pieces, put it into the cracking furnace for thermal cracking, there are many processing links, the production process is long, and it is easy to cause secondary pollution
The patent application number is 200610028197.5, the publication date is December 06, 2006, and the Chinese invention patent application with the announcement number CN1872953 discloses a "integral waste tire pyrolysis process", which can put the entire waste tire into the pyrolysis kettle for one-time rapid pyrolysis For combustible gas, oil, coarse carbon black and scrap steel wire, the process links are reduced, but the cracking kettle needs 600-800°C hot air flow to heat up, and the hot air flow is produced by combusting combustible gas and oil in the combustion chamber, which itself requires consumption A large amount of fuel energy, and because the combustion chamber is independent from the cracking kettle, the heat generated by combustion is lost in the transfer process, which is not conducive to saving energy and improving efficiency

Embodiment 1

[0024] Embodiment 1, as shown in Figures 1, 2, and 3, the feed port (7) of the pyrolysis furnace body of furnace (1) is opened, and 100 kg of integral waste tires that do not need to be broken or cut off after cleaning and descaling are dropped into the pyrolysis furnace , close the feed inlet (7), turn on the power supply to increase the temperature in the cracking furnace, detect the temperature in the furnace through the thermocouple (4) probe, and transmit the temperature information in the furnace to the control cabinet. Control the heater to let the waste tires in the pyrolysis furnace react at 250°C-350°C for 60 minutes. The waste tires are cracked to generate a large amount of pyrolysis gas, which enters the condenser through the exhaust pipe (5) on the pyrolysis furnace body for cooling Separate, obtain combustible gas and mixed oil by twice condensation, after turning off the power supply, open the discharge port (2) of the furnace body of the cracking furnace, the re...

Embodiment 2

[0025] Embodiment 2, as shown in Figures 2, 3, and 4, the environmentally friendly waste tire electric energy cracking equipment includes a cracking furnace, a condenser and a control cabinet, and the cracking furnace and the condenser are connected by an exhaust pipe (5). Even (4) is connected with the control cabinet by cables, and the heater (1-3) in the cracking furnace is connected with the control cabinet by a power supply control line; the cracking furnace mainly includes a cracking furnace body (1), a cracking furnace body (1 ) has a feed inlet (7) at one end, and a discharge outlet (2) at the other end, adopting a hydraulic pressure opening and sealing device, and an exhaust pipe (5), a safety explosion-proof device (3), The power connection terminal (6) and the thermocouple (4), the probe of the thermocouple (4) is inserted into the innermost layer of the cracking furnace body (1) to measure the temperature in the furnace body; the furnace wall of the cracking furnace...

Abstract

The invention relates to a waste tyre cracking process and device thereof. The process includes steps of cleaning tyre, cracking tyre by electrical energy heating, and reclaiming combustible gas, mixed oil, steel wire and crude carbon black. The device used for cracking process includes cracking furnace, condenser and control cabinet. The method reduces correlative devices such as burning equipment, burning chamber and smoke discharging pipe by using electrical energy as heating source; depresses energy loss to lowest by putting electrothermal heater in the cracking furnace; and is environment friendly due to not having smoke, noise, leakage, sewage, waste gas and castoff in cracking process.

Description

technical field [0001] The invention relates to a pyrolysis recovery process and equipment for rubber and plastic products, in particular to a waste tire pyrolysis process and equipment. Background technique [0002] We are in an era of more and more cars, which undoubtedly brings us opportunities and challenges. The coming of the car era means that there are more and more waste tires, and black pollution has caused harm to the environment and brought pressure to human beings. To alleviate this problem, it is ideal to use thermal pyrolysis at present. The traditional method is to put the waste tire block into a pyrolysis furnace for dry distillation and pyrolysis to recover fuel oil, combustible gas and carbon black. Pull out the ring-shaped steel wire in the waste tire, then cut the waste tire into pieces, put it into the pyrolysis furnace for thermal cracking, there are many processing links, the production process is long, and it is easy to cause secondary pollution. The...
