Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a high-temperature resistant, anti-blocking, detachable and cleanable multi-tube dust collector. Background Art

[0002] Multi-tube dust collector is a high-efficiency, low-resistance dust removal equipment. Its operating principle is: when the dust-laden gas enters the dust collector, it passes through the spiral guide structure and rotates at high speed inside the cyclone. Under the action of centrifugal force, the dust and gas are separated, and the dust falls into the ash hopper. The purified gas forms an ascending vortex, which is collected in the gas collecting chamber through the exhaust pipe and discharged through the outlet to achieve the dust removal effect.

[0003] Existing multi-tube dust collectors, such as the axial-flow multi-tube cyclone dust collector disclosed in Patent No. 201210171809.1 and the high-temperature resistant ceramic multi-tube dust collector disclosed in Patent No. 201410283136.8, all use ceramic structures for the cyclones. Due to the high temperature of the dust-laden gas, in the cold northerly weather environment, the large temperature difference will cause the ceramic cyclones to break. In addition, the dust in the dust-laden gas is easily accumulated and blocked at the spiral guide structure. Existing cyclones are mostly integrated with the exhaust pipe and are difficult to disassemble and clean. Long-term use will increase the smoke flow resistance and reduce the dust removal efficiency.

[0022] Specifically, a plurality of slide grooves 711 are provided and are spaced apart along the circumference of the exhaust pipe 71 ; a plurality of convex strips 725 are provided and are spaced apart along the circumference of the straight pipe 722 .

[0023] Specifically, the receiving body 724 is located above the cyclone 721, and the bottom of the receiving body 724 is a conical structure, which facilitates the dust-containing gas to enter the spiral guide structure 723 on the top side of the cyclone 721, thereby playing a guiding role.

[0024] Specifically, a ring-shaped slot 726 is provided at the top of the receiving body 724 for the bottom end of the exhaust pipe 71 to be inserted into, thereby further fixing the exhaust pipe 71.
