Description

TECHNICAL FIELD

[0001] The utility model relates to oil sludge treatment equipment technical field, concretely is a kind of coking device of oil sludge pyrolysis pipeline. BACKGROUND

[0002] Oil sludge pyrolysis rotary kiln is an advanced solid waste treatment technology, and the working principle of oil sludge pyrolysis rotary kiln is mainly based on pyrolysis technology, i.e. in the environment without oxygen or micro-oxygen, organic matter is decomposed by heating, and in the pyrolysis process, the pyrolysis oil gas and dust crystallization and tar condensation coking, which easily lead to the blockage of pyrolysis gas circulation pipeline of pyrolysis device, affect the normal work of equipment.

[0003] Patent (CN115851294B) discloses a dust-containing pyrolysis oil gas outlet anti-blocking self-cleaning device, which comprises a pyrolysis chamber, a self-cleaning double helix system and a pyrolysis oil gas rapid cooling section. The pyrolysis chamber is provided with a pyrolysis gas outlet pipeline at the top. The self-cleaning double helix system comprises an 8-shaped sleeve fixed at one end of the pyrolysis gas outlet pipeline, an axis-free double helix arranged in the 8-shaped sleeve, and a driving mechanism sealingly fixed at the other end of the 8-shaped sleeve. The fixed end of the axis-free double helix is connected with the driving mechanism, and the free end extends into the pyrolysis gas outlet pipeline. The axis-free double helix comprises two axis-free helices partially engaged with each other, and each axis-free helix is provided with a self-excited vibration paddle matched with each other. The two self-excited vibration paddles collide to produce high-frequency vibration during the rotation of the two axis-free helices, so that the coke blocks adhered to the axis-free helix fall off. By using the invention, the furnace can be prevented from stopping due to the blockage of the connecting pipe between the pyrolysis gas outlet and the condenser inlet, and the continuous operation time of the pyrolysis equipment can be improved.

[0004] The dust-containing pyrolysis oil gas outlet anti-blocking self-cleaning device in the above-mentioned patent utilizes the collision of self-excited vibration paddles, and then transmits vibration from the self-excited vibration paddles to the axis-free helix. However, a large amount of energy is lost during the transmission of vibration from the self-excited vibration paddles to the surface of the axis-free helix, and the vibration effect of the axis-free helix is not good, resulting in poor coke block falling effect on the surface of the axis-free helix.
