Abstract

The invention belongs to the field of flammable dust cleaning, and discloses non-contact pipeline dust cleaning method and system. the system comprises a cleaning device capable of moving in a pipeline by means of airflow thrust and a traction line used for controlling the moving speed of the cleaning device; the cleaning device comprises a hollow body and a tail part arranged in the body; an accelerating air duct with a gradually reduced section is formed between the outer wall of the tail part and the inner wall of the body, and an outlet of the accelerating air duct faces the inner wall of the pipeline; and a walking mechanism making contact with the inner wall of the pipeline is arranged on the body. The accelerating air duct with the sectional area gradually reduced in the air direction and facing the inner wall of the pipeline is arranged in the pipeline, so that air in the pipeline is accelerated by the accelerating air duct to form rapid airflow, and dust on the inner wall of the pipeline is blown up; and compared with the prior art, the non-contact type dust cleaning mode is adopted, the problems of static electricity, sparks, friction heat and the like can be effectively avoided, and therefore explosion is avoided, and dust cleaning work is safer.

Description

technical field [0001] The invention relates to the field of combustible dust cleaning, in particular to a non-contact pipeline dust cleaning method and system. Background technique [0002] Combustible dust refers to dust, fibers or flying flocs that can burn or smolder in the air, and form explosive mixtures with air at normal temperature and pressure. When the combustible dust suspended in the air reaches the explosion point, it will explode when it encounters a fire source. Therefore, it is very important to clean up the accumulated dust in the dust removal pipeline in time. [0003] The original dust cleaning methods can be divided into two categories: chemical cleaning and physical cleaning. Chemical cleaning will produce industrial waste liquid, which is costly to deal with, and the dust is likely to react with chemicals and cause explosions, so factories generally use physical cleaning methods. Patent CN202010635669.3 discloses a passively driven pipeline dust clea...
