Embodiment 1

[0040] Embodiment 1, a high-efficiency treatment system for waste tire rubber particles:

[0041] as attached Figure 1~4 The high-efficiency treatment system for waste tire rubber particles shown includes a cracking furnace 100 , a molten salt combustion furnace 200 , an oil-gas separator 300 , a desulfurization tower 400 , an air tank 500 , an oil tank 600 , and a carbon black bin 20 . The molten salt combustion furnace 200 is used to heat the molten salt and supply the molten salt to the cracking furnace 100; The gas outlet 301 enters the gas tank 500 through the desulfurization tower 400, and the separated oil enters the oil tank 600 from the liquid outlet of the oil-gas separator 300; here, the gas in the gas tank 500 can be supplied to the molten salt combustion furnace 200 for recycling; The carbon black produced in the cracking furnace 100 directly enters the carbon black bin 20 .

[0042] Among them, an oil-gas condenser 19800 is connected between the oil-gas separa...

Embodiment 2

[0051] Embodiment 2, an efficient treatment system for waste tire rubber particles:

[0052] The difference between the second embodiment and the first embodiment is that there are several ribs 12 distributed on the inner surface of the material reaction tube 120 , and the length direction of the ribs 12 is arranged along the axial direction of the material reaction tube 120 . The length direction of the strip-shaped rib 12 is consistent with the conveying direction of the rubber particles. On the one hand, the resistance to the conveying of the rubber particles is small; More fully and evenly.

Embodiment 3

[0053] Embodiment 3, an efficient treatment system for waste tire rubber particles:

[0054] The difference between the third embodiment and the first embodiment is that the inner surface of the material reaction cylinder 120 has a number of protrusions 13 uniformly distributed, and the protrusions 13 are formed by extrusion from the outer surface of the material reaction cylinder 120 to the inner surface. On the one hand, the protruding part 13 can drive the rubber particles to move in the circumferential direction, and improve the mixing effect of the rubber particles; area, improve the heat conduction effect, and make the rubber particles in the cylinder more fully and evenly heated.

Abstract

The invention provides a high-efficiency treatment system for waste tire rubber particles, which belongs to the field of hydrocarbon oil cracking. The invention includes a cracking furnace, a molten salt furnace, and a combustion chamber. The cracking furnace includes an outer cylinder, a material reaction cylinder, a rotating shaft, a spiral blade, a first driving part, a second driving part, the inner wall of the molten salt flow section on the outer cylinder and the material A sealed chamber for molten salt flow is formed between the outer walls of the material reaction section on the reaction cylinder. A sealed feeder is connected to the feed port, and a sealed discharge device is connected to the discharge port. It also includes an oil-gas separator, a desulfurization tower, and a gas tanks and oil tanks and air preheaters. The colloidal particles can be continuously cracked in the cracking furnace, and the cracking efficiency is high; the thermal stability of the molten salt heating is good, the temperature difference is easy to control, and the molten salt can circulate and flow, and the energy consumption is low; the material reaction cylinder can be rotated independently, so that the inside of the cylinder The colloidal particles are fully and evenly heated, so that the cracking is more complete and the recycling efficiency of raw materials is improved; the recycling of cracking products not only greatly improves the energy utilization rate, but also is environmentally friendly.

Description

technical field [0001] The invention relates to the field of hydrocarbon oil cracking, in particular to a high-efficiency treatment system for rubber particles of waste tires. Background technique [0002] With the rapid rise of the automobile industry, while bringing convenience to people's life, a large amount of waste tires are produced every year. Waste tires are difficult to degrade in the natural environment. In the past, waste tires were mainly disposed of by incineration, burial, crushing, etc., but these methods will cause huge potential harm to the natural environment. The disposal of waste tires has always been a major problem for everyone. [0003] Waste tires are mainly composed of synthetic rubber, natural rubber, anti-aging agent, carbon black, plasticizer, sulfur and other organic and inorganic substances, which have high economic value. In order to not only solve the problem of resource recycling, but also minimize the damage to the environment. At presen...
