Problems solved by technology

To alleviate this problem, it is ideal to use pyrolysis at present. The traditional method is to put the waste tire block into the pyrolysis furnace for dry distillation and cracking, and recover fuel oil, combustible gas and carbon black from it. The ring-shaped steel wire in the waste tire is pulled out, and then the waste tire is cut into pieces and put 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 publication 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

[0025] Embodiment 1, as figure 1 , 2 , shown in 3, the feed inlet (7) of pyrolysis furnace body of heater (1) is opened, the integral waste tire 100kg that need not be broken or cut off after cleaning and descaling is put into cracking furnace, close feed inlet (7), Turn on the power to increase the temperature in the cracking furnace, measure the temperature in the furnace through the thermocouple (4) probe, and transmit the temperature information in the furnace to the control cabinet, and the control cabinet controls the heater according to the temperature in the furnace, so that the temperature in the cracking furnace The waste tires are reacted at 250°C-350°C for 60 minutes, and the waste tires are cracked to produce a large amount of cracked gas. The cracked gas enters the condenser through the exhaust pipe (5) on the furnace body of the cracking furnace for cooling and separation, and the combustible gas is obtained through two condensations. and mixed oil, after turn...

Embodiment 2

[0026] Embodiment 2, as figure 2 , 3 , 4, the environmentally friendly waste tire electric cracking equipment includes a cracking furnace, a condenser and a control cabinet, the cracking furnace and the condenser are connected through an exhaust pipe (5), and the thermocouple (4) in the cracking furnace is connected to the control cabinet through a cable Wire connection, the heater (1-3) in the cracking furnace is connected to the control cabinet through the power control line; the cracking furnace mainly includes a cracking furnace body (1), and one end of the cracking furnace body (1) has a feed port (7) , the other end discharge port (2) adopts a hydraulic pressure opening sealing device, and an exhaust pipe (5), a safety explosion-proof device (3), a power connection terminal (6) and a thermocouple are also installed on the cracking furnace body (1) (4), the probe of the thermocouple (4) is inserted into the innermost layer of the cracking furnace body (1) to measure the...

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 pyrolysis at present. The traditional method is to put the waste tire block into the pyrolysis furnace for dry distillation and cracking, and recover fuel oil, combustible gas and carbon black from it. The ring-shaped steel wire in the waste tire is pulled out, and then the waste tire is cut into pieces and put into the cracking furnace for thermal cracking. There are many processing links, the production process is long, and it is easy to cause secondary p...
