Description

Technical Field

[0001] The utility model relates to the field of waste gas dust removal, in particular to a multi-tube ceramic dust collector. Background Art

[0002] The multi-tube ceramic dust collector is a high-efficiency, low-resistance dust removal device with a wide range of applications. Its working principle is: when the dust-laden gas enters the dust collector, it passes through the ceramic guide 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 dust collecting box (ash hopper) and is discharged through the ash discharge valve. The purified gas forms an ascending vortex, which is collected in the air collecting chamber through the exhaust pipe and discharged from the chimney through the outlet to achieve the dust removal effect. The existing multi-tube ceramic dust collector has the following problems:

[0003] First, the ceramic cyclone body will be damaged if it works under high temperature for a long time. The internal gaps of some existing multi-tube ceramic dust collectors are sealed with concrete. This design makes it difficult to replace the cyclone body, and when replacing it, all the cyclone bodies need to be broken and dismantled, and then new cyclone bodies need to be installed, which is wasteful.

[0004] Second: After the ceramic cyclone body has been working for a long time, due to the accumulation of dust, adjacent cyclones are prone to stick together. When replacing the cyclones, the cyclones that are stuck together need to be broken together and then replaced together.

[0005] Third: the existing multi-tube ceramic dust collectors, such as the ceramic multi-tube dust collector disclosed in Chinese patent CN205461410U, all have the problem of difficulty in replacing ceramic tubes and the problem of needing to break adjacent ceramic tubes in order to replace one ceramic tube. Utility Model Content
