Description

Homogenizing pyrolysis reaction device with mesh bag filtering structure
Technical Field
The utility model relates to a homogenizing pyrolysis reaction device with a mesh bag filtering structure, which is used for a pyrolysis gasification process of waste tire rubber, and belongs to the technical field of environmental protection.
Background
At present, most of domestic and foreign waste tyre thermal cracking reactors are intermittent roller reactors, and the operation characteristics of the reactor are that the reactor is carried out in batches, and four processes of feeding, heating, cooling and deslagging are carried out on each batch. Obviously, the disadvantage of this thermal cracking reactor is its intermittence, which is due to the periodic heating and cooling, which results in low efficiency and large energy loss; in addition, the wall sticking phenomenon is easy to generate, namely the phenomenon that the waste tires are softened and stuck on a heating surface after being heated, and after the wall sticking phenomenon occurs, local overheating and secondary cracking can occur, so that normal production is affected, and when serious, the waste tires are required to be shut down for maintenance. Continuous feeding has been used instead of batch feeding, but continuous feeding brings new problems, namely dynamic and static sealing of the reactor, which is particularly remarkable for large reactors; in addition, the phenomenon of wall sticking is not solved, so that the reactor is not popularized. Chain reactors have also been proposed in which waste tires are heated by heating the outside of the reactor and then thermally cracked by means of heat radiation. However, according to the theory of heat radiation, in order to make the waste tires in the reactor reach a sufficient thermal cracking temperature, the wall of the reactor should be much higher than it, which makes the metal wall material difficult to withstand, and therefore, such a reactor having poor external heating heat transfer property has not been popularized.
The utility model patent number CN2775056Y discloses a waste tire thermal cracking reactor, which belongs to a cracking reactor and structurally comprises a reactor body and an oil gas outlet, wherein the oil gas outlet is arranged at the top of the reactor body, an automatic feeding device is arranged at the top of the reactor body, an automatic discharging device is arranged at the bottom of the reactor body, a heating pipe is wound on a shell at the middle lower part of the reactor body, a heating carrier inlet is communicated with a heating pipe at the lower part, and a heating carrier outlet is communicated with a heating pipe at the upper part.
The Chinese patent application with publication number CN110396418A discloses a continuous internal heating type waste tire thermal cracking reactor, which is a rectangular metal shell, and a plurality of internal heat source heaters and internal heat source scraper heaters are arranged in the shell. The waste tyre falls onto the surface of the internal heat source heater from the feed hopper, and is scraped by the internal heat source scraper heater, so that the waste tyre moves downwards layer by layer until the slag hole is discharged. When the waste tyre moves downwards in the reactor, the waste tyre is heated by the internal heat source heater and the internal heat source scraper heater to generate pyrolysis gas, which is led out from the pyrolysis gas leading-out pipe and condensed into fuel oil by the condenser.
However, the above-mentioned conventional pyrolysis device has the following drawbacks in pyrolysis gasification of waste tire rubber: 1. the two sides of the cracking reaction device are heated, the heat transfer is uneven, and the material reaction is insufficient; 2. the heating is uneven, the cracking reaction device is possibly deformed, and the service life is reduced; 3. the cracking space of the cracking reaction device is large, the feeding is uneven, and the accumulation of materials is easy to form a dead space; 4. the expansion dislocation is easy to be caused by different orientations of all parts of the cracking reaction device; 5. the blanking can mix oil and carbon black, and filtering separation is needed.
Therefore, the homogenizing pyrolysis reaction device with the mesh bag filtering structure has the advantages of simple structure, uniform distribution, difficulty in forming stacked materials, more uniform heat transfer, further improvement of pyrolysis reaction efficiency, more sufficient material reaction, uniform heating, avoidance of expansion dislocation, and improvement of the service life of the pyrolysis reaction device, and is a technical problem to be solved in the technical field.
