[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] As attached Figures 1-2 A dust removal pipeline reversing connection device for a coke screening system includes a device body 1. The inner cavity of the device body 1 is used to connect two dust removal pipelines in different directions. A first adhesion layer 2 is provided on the cavity wall surface of the inner cavity facing the direction of dust-laden gas flow. A second adhesion layer 3 is provided on the other cavity wall surfaces of the inner cavity of the device body 1. By providing adhesion layers on the inner cavity wall, some coke particles and coke dust in the gas can be adsorbed onto the cavity wall surface, thereby forming a protective layer of a certain thickness. This avoids direct contact between coke particles and coke dust in the subsequent gas and the cavity wall, thereby reducing wear at the reversing point of the dust removal pipeline.

[0018] Both the first adhesive layer 2 and the second adhesive layer 3 have rough surfaces. The uneven, rough surfaces help to increase the adsorption surface and enhance the adsorption effect.

[0019] The adhesion surface of the first adhesion layer 2 is inclined towards the bend of the dust-laden gas within the inner cavity of the device body 1. This provides a guiding effect, reducing the resistance encountered by the dust-laden gas at the bend, and simultaneously reducing the excessive impact force of coke particles and coke dust on the formed protective layer. This prevents severe detachment of the adhesion particles, which would affect the protective effect, thereby reducing wear on the adhesion layer and further extending the service life of the dust removal pipeline at the reversing point.

[0020] The first adhesive layer 2 is a wear-resistant structural layer, made of an adsorbent material with higher wear resistance, which reduces the wear caused by the relative slippage of a small amount of tar from the surface of the adhesive layer when it peels off, thereby further enhancing the durability of the adhesive layer.

[0021] An elastic layer 4 is disposed between the first adhesive layer 2 and the cavity wall surface. The elastic layer can act as a buffer to offset the impact force generated by the collision of larger particles, thereby protecting the cavity wall and the protective layer formed by adsorbed particles.

[0022] The first adhesive layer 2 is integrally arranged with the elastic layer 4. The elastic layer is fixedly connected with the cavity wall surface through bonding or screw fastening or the like, and the first adhesive layer 2 is combined with the coke breeze particles to form a reinforced protective layer, thereby forming a wear-resistant and anti-collision protective layer with a stable structure relative to the cavity wall surface, so that the formed protective layer is more durable and continuously provides a protective effect on the reversing connection of the dust removal pipeline, effectively prolonging the service life of the reversing connection of the dust removal pipeline.

[0023] Preferably, the device body 1 adopts a square box larger than the pipe diameter of the dust removal pipeline, providing sufficient buffer space, so that, except for the cavity wall surface provided with the first adhesive layer, the remaining cavity wall surfaces are only impacted by a small amount of dispersed particles, and the first adhesive layer and the second adhesive layer can both adopt rubber material, which has adsorption, elasticity and wear resistance.

[0024] Embodiment: The device body 1 includes two connectors 11, and the inner cavities of the two connectors 11 are in communication through the buckle interfaces 12 of the two connectors 11. The two connectors 11 are relatively rotatable through the buckle interfaces 12. When the two connected dust removal pipelines extend along the horizontal plane, the two connectors can be adjusted at any angle according to the pipeline layout requirements, and the first adhesive layer 2 is arranged on the cavity wall surface of the inlet end connector facing the air inlet, the cavity wall surface of the outlet end connector facing the buckle interface of the inlet end connector, and the cavity wall surface where the air outlet is located, so that the protective effect can be ensured when the angle is adjusted to any angle.

[0025] Preferably, as shown in the accompanying drawings, the inner cavities of the two connectors 11 are vertically communicated. Figure 2 When the dust-containing gas enters from the upper end connector, the coke breeze with large particles falls under the action of gravity and negative pressure suction, and only a small amount of coke breeze with small particles and coke powder acts on the first adhesive layer. The coke powder and the small particles of the coke breeze are more easily adsorbed to form a protective layer and are not easy to fall off. At the same time, the probability of the large particles of the coke breeze directly impacting the protective layer is reduced, thereby further enhancing the durability of the formed protective layer as a whole, and the large particles of the coke breeze are discharged with the airflow, avoiding a large amount of accumulation.

[0026] The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
