The main technical effect is that the spray gun and the powder pump spray boric acid powder into the coking material in the heat exchanger pipeline, which can effectively reduce the viscosity of the coking material, and then make it fall in the high temperature state to achieve the purpose of cleaning.

[0004] In the waste pyrolysis process, heating will cause the coking adhesion of high molecular organic matter and dust particles on the kiln cylinder wall, resulting in the decline of heat transfer effect, and at the same time, due to the coking adhesion on the inner wall of the kiln, the diameter of the cylinder body becomes smaller, which will cause blockage. After the coking device in the prior art cleans the coking, the debris will accumulate at the bottom of the kiln cylinder body, and then the material cannot be effectively transported. Therefore, a rotary type decoking material guiding device is proposed to solve the problem that the debris will accumulate at the bottom of the kiln cylinder body after the coking device in the prior art cleans the coking, and then the material cannot be effectively transported.

[0035] The utility model discloses, the cylinder 1 keeps rotating, through the fixed plate 7 that sets up on the inner wall of cylinder 1 and the abutment of scraper 4, through the fixed plate 7 and pushes scraper 4 and drives scraper 4 and keeps rotating, and then the coking on the inner wall of cylinder 1 is cleaned up, and in the cleaning of the same time, through the flow guide passage 6 between the flow guide plate 5 that sets up on scraper 4, the coking debris that is cleaned down from the inner wall of cylinder 1 is transported to the side of cylinder 1, prevents the coking debris and cokes again on the inner wall of cylinder 1, can guarantee the heat transfer efficiency inside cylinder 1 and can transport the material in cylinder 1 to a certain extent, prevents the accumulation.

[0036] Working principle:

[0037] When the external driving mechanism drives cylinder 1 to keep counterclockwise rotation, and the fixed plate 7 on the inner wall of cylinder 1 and one of scraper 4 abut, through the fixed plate 7 and drive the central shaft 2 to keep rotating, and then drive a plurality of scrapers 4 to keep rotating inside the cylinder 1, the coking attached on the inner wall of cylinder 1 is scraped off and broken, and coking debris is formed;

[0038] At this time, since the flow guide plate 5 on the outer wall of the scraper 4 is arranged in the direction of conveying the material of the cylinder 1, the coking debris can flow from the flow guide passage 6 between the flow guide plates 5 to the conveying direction of the cylinder 1 while the scraper 4 is rotating, thereby promoting the flow of the material.

[0039] As shown in Figures 5-9 When the central shaft 2 rotates by a certain angle, the scraper 4 is separated from the fixed plate 7, and under the action of gravity, the central shaft 2 and the scraper 4 are driven to continue rotating, and then the coking attached on the inner wall of the cylinder 1 is cleaned by the scraper 4.

[0040] Since the central shaft 2 does not need an additional motor for driving, the maintenance cost is reduced. The scraper 4 realizes coke cleaning by gravity, which is more energy-saving.
