Description

Technical Field

[0001] The invention belongs to the technical field of waste material treatment, and in particular relates to equipment for making clean fuel and carbon black from waste tires and waste plastics. Background Art

[0002] At present, the main ways to deal with waste tires or waste plastics are: landfill, incineration, incineration power generation and oil refining. Among them, landfill is just burying the waste underground or elsewhere, which will occupy a lot of land, and the buried waste may pollute groundwater, etc., and landfill pollution will achieve the recycling of waste resources, resulting in resource waste. Incineration and incineration power generation will produce toxic gases, causing secondary pollution, which is extremely harmful to human health.

[0003] Oil refining is a method of converting waste tires into reusable resources by thermal cracking. In the prior art, waste tires or waste plastics are also processed by oil refining. For example, CN204550476U discloses a waste tire or waste plastic harmless and resource processing system, wherein a feeding device is connected to a cracking kettle, a slag outlet of the cracking kettle is connected to a carbon black bin through a conveying elevator, a steam outlet of the cracking kettle is connected to a downstream settling tank, a primary condenser and an oil-water separator in sequence through a steam drum, and a steam outlet of the oil-water separator is connected to a hot blast furnace through a pipeline; the oil outlet of the oil-water separator is connected to a downstream cracking oil storage tank, a preheating tank, a catalytic reaction device, a secondary condenser and a separation tank through a pipe; the steam outlet of the separation tank is connected to a hot blast furnace steam in sequence through a pipe; the steam outlet of the separation tank is connected to a hot blast furnace steam inlet through a pipe; the oil outlet of the separation tank is connected to a downstream degumming tank, a decoloring tank, a deodorizing tank, a filter and a finished oil tank through a pipe. The patent discloses a harmless and resource-based treatment system for waste tires or waste plastics, which solves the problems of resource waste, secondary pollution caused by landfill, incineration for power generation, traditional oil refining, and permanent dead soil, and can refine waste tires or waste plastics into fuel oil.

[0004] It is undeniable that the harmless and resource-based treatment system for waste tires or waste plastics disclosed in the patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: the oil vapor coming out of the cracking furnace is cooled after passing through the oil-water separator and enters the cracking oil storage tank, and the oil product at this time is crude oil; the crude oil in the cracking oil storage tank is preheated by the preheating tank and enters the catalytic reaction device. After the crude oil is processed in this step, it is condensed, degummed, decolorized and deodorized to form essential oil. As can be seen from the above, the system disclosed in the patent needs to refine the waste materials into crude oil first, and then refine the crude oil into essential oil, that is, it takes two steps to complete the refining process, and multiple tanks and other devices need to be used in the middle, which will increase the refining cost; in addition, the crude oil needs to be preheated in the preheating tank before entering the catalytic reaction device, which will increase the heat demand in the refining process to a certain extent.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0011] A slag discharge pipe connected to a slag discharge port in the middle of the rear end of the horizontal cracking furnace;

[0012] A steam drum connected to a slag outlet in the middle of the rear end of the horizontal cracking furnace through a pipeline;

[0013] A multi-stage catalytic tower, the multi-stage catalytic tower includes a plurality of catalytic tower bodies, two adjacent catalytic tower bodies are connected by pipelines; the bottom of the catalytic tower body close to the steam drum is connected to the top of the steam drum through a pipeline, and its top is connected to the bottom of the next catalytic tower body through a pipeline; a heating chamber is sleeved and fixed on the outside of each catalytic tower body, the bottom of the heating chamber close to the steam drum is connected to the outlet of the exhaust pipe through a pipeline, and its top is connected to the bottom of the next heating chamber through a pipeline.

Secondly, the flue gas generated in the heating furnace is introduced into the heating chamber through the exhaust pipe to heat the catalytic tower body, which helps the gas components to further catalytically crack in the catalytic tower body, and can also make full use of the heat in the flue gas. The design of the entire device is ingenious and fits practical applications, and has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a clear and complete description of the technical solution of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example

[0024] See attached Figure 1 , equipment for making clean fuel and carbon black from waste tires and waste plastics, including:

[0025] A heating furnace 10, the top of which is connected to an exhaust pipe 11;

[0026] The horizontal cracking furnace 20 has a furnace body that penetrates the heating furnace 10, and a gap is left between the outer wall of the horizontal cracking furnace 20 and the inner wall of the heating furnace 10 to form a clamping cavity that is connected to the exhaust pipe 11. It should be supplemented here that the two ends of the heating furnace 10 are in contact with the outer wall of the horizontal cracking furnace 20 to prevent the hot air in the heating furnace 10 from leaking out; wherein, a feeding port (not shown in the drawings) is provided in the middle of the front end of the horizontal cracking furnace 20, and the processed waste tire plastic enters the horizontal cracking furnace 20 through the feeding port.

[0027] A slag discharge pipe 30 is connected to a slag discharge port 21 at the middle of the rear end of the horizontal cracking furnace 20;

[0028] The steam drum 40 is connected to the slag outlet 21 at the middle of the rear end of the horizontal cracking furnace 20 through a pipeline;

[0029] The multi-stage catalytic tower 50 includes at least two catalytic tower bodies 51, and the two adjacent catalytic tower bodies 51 are connected by pipelines; the bottom of the catalytic tower body 51 near the steam drum 40 is connected to the top of the steam drum 40 through a pipeline, and the top of the catalytic tower body 51 near the steam drum 40 is connected to the bottom of the next catalytic tower body 51 through a pipeline; a heating chamber 60 is sleeved and fixed on the outside of each catalytic tower body 51, the bottom of the heating chamber 60 near the steam drum 40 is connected to the outlet of the exhaust pipe 11 through a pipeline, and the top of the heating chamber 60 near the steam drum 40 is connected to the bottom of the next heating chamber 60 through a pipeline. It should be supplemented that the top and bottom of the heating chamber 60 are sealed, and there is a gap between the inner wall and the outer wall of the catalytic tower body 51.

[0030] In this embodiment, the heating furnace 10 heats the horizontal cracking furnace 20 by combustion heating to crack the waste tire plastic in the horizontal cracking furnace 20; when the oil vapor generated by the cracking of the waste tire plastic is discharged through the slag outlet 21 in the middle of the rear end of the horizontal cracking furnace 20, the oil vapor enters the steam drum 40 through the pipeline, and after passing through the steam drum 40, the gas in the oil vapor enters the catalytic tower body 51 through the pipeline, while other impurities in the oil vapor are heavier and cannot enter the catalytic tower body.

[0031] In particular, after the gas in the oil product vapor enters the catalytic tower body 51, the gas components are further catalytically cracked in the catalytic tower body 51, and after catalytic cracking in multiple catalytic tower bodies 51, the essential oil vapor is obtained, and the essential oil vapor is further condensed by an external condensing device to obtain clean fuel essential oil. In the process of the gas in the oil product vapor entering the catalytic tower body 51, the flue gas generated by the combustion of the heating furnace 10 enters the heating chamber 60 through the exhaust pipe, and then heats the catalytic tower body 51, which helps the gas components to further catalytically crack in the catalytic tower body 51. The flue gas discharged from the last heating chamber 60 is then purified by an external device and discharged.

[0032] In addition, the waste tire plastic is cracked in the horizontal cracking furnace 20 to produce non-gas materials, which are discharged from the slag discharge port and enter the external storage container through the slag discharge pipe 30, and are cooled to form carbon black.

[0033] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes. The scope of the present invention is intended to be limited by the claims and their equivalents.
