[0002] The existing cyclone dust collector has a single cylinder structure, which is inadequate in dealing with special gases. During long-term operation, the special gases refer to combustible gases, which mainly consist of carbon monoxide, hydrogen, methane, carbon dioxide, nitrogen, water vapor, as well as some high-molecular hydrocarbon gases, tar gas, wood vinegar gas, dust, and materials with a particle diameter of 1 - 8 millimeters. Tar is a general term for a series of complex compounds containing aromatic hydrocarbons and aromatic hydrocarbon derivatives produced during the biomass conversion process and has corrosiveness.
[0003] However, the existing devices have the following problems:
[0004] Tar begins to condense and precipitate at a certain temperature. As the pipeline extends and the temperature gradually decreases, a large amount of tar and water vapor mix and condense, threatening the safety of the pipeline and equipment. Since tar itself has a certain calorific value, its incomplete combustion will also cause energy waste.
[0005] The existing devices need to be shut down regularly for cleaning after long-term operation, resulting in the inability of the equipment to operate continuously for a long time and affecting the operation of the equipment.
[0006] Therefore, in order to solve the above problems, a heat tracing and insulation cyclone dust collector is proposed. Content of the Utility Model
