High-efficiency dust removal system and method in pneumatic delivery pipe

Abstract

The invention discloses a high-efficiency dust removal system in a pneumatic delivery pipe. The high-efficiency dust removal system in the pneumatic delivery pipe comprises a pneumatic material delivery pipeline; a dust measuring device and a spraying device which are connected with a control device and are connected in sequence in a flowing direction of a material are also mounted on the pneumatic material delivery pipeline; the control device regulates and controls the spraying device to achieve a spraying effect which is suitable for a dust amount according to the change of the dust amountin the pneumatic material delivery pipeline. According to the high-efficiency dust removal system in the pneumatic delivery pipe, a reasonable spraying effect can be achieved according to the dust amount in the pipe, so that the requirement on local or overall dust removal of the pipeline is met, and the problems that material deterioration or pipeline blockage caused by excessive spraying, and local heat accumulation, dust explosion and the like caused by insufficient spraying can also be prevented.

Description

technical field [0001] The invention relates to an air pneumatic conveying system suitable for dilute phase and dense phase coal and grain particles, in particular to an efficient dust removal system and method in a pneumatic conveying pipe. Background technique [0002] Pneumatic conveying system is a conveying system that uses airflow with a certain pressure and a certain speed to convey powder and granular materials in the pipeline. In the pneumatic conveying pipeline, it is generally a mixed medium of air and powder materials, which belongs to the category of gas-solid two-phase flow. [0003] During the pneumatic conveying process, due to the friction between the material and the pipeline and the friction between the materials, the amount of dust in the conveying pipeline gradually increases. For the transportation of coal and grain particles, when the amount of dust in the pipe increases to the explosion point, Very prone to explosion accidents. [0004] Therefore, b...
