Automatic dedusting method and system for dust removal pipeline

Abstract

The invention discloses an automatic dedusting method and system for a dust removal pipeline. The automatic dedusting method comprises the steps that dust deposition weight data of each detection point in the dust removal pipeline are obtained; the dust deposition thickness of each detection point is calculated according to the dust deposition weight data; the pipeline blockage degree P and the dust deposition rate V of each detection point are calculated according to the dust deposition thickness, and the average dust deposition rate V<avg> of all the detection points is calculated according to the dust deposition rates V; when the pipeline blockage degree P of a certain detection point reaches the set value, dedusting is conducted by increasing the air door open degree of a pipeline body where the detection point is located; and when the average dust deposition rate V<avg> reaches the set value, the dust deposition rate is decreased by increasing the air door open degree of a main pipeline body. According to the automatic dedusting method and system for the dust removal pipeline, energy consumption of a dust removal system can be significantly reduced; pipeline abrasion is effectively relieved; long-term stable operation of the dust removal system is ensured; and in addition, the method adopts an automatic feedback closed-loop control mode, so that manual operation is not needed, and the operation and maintenance workload is small.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a method for cleaning dust accumulated in a dust removal pipeline of the dust removal equipment. The invention also relates to a system capable of cleaning the accumulated dust in the dust removal pipeline of the dust removal equipment. Background technique [0002] The dust removal pipeline is an important part of the dust removal system. When the dust accumulation in the pipeline is caused by the long-term low flow rate of the dust removal pipeline, the dust particles in the dusty airflow are too large, etc., the pipeline will be blocked and the continuous and stable operation of the dust removal system will be affected. When the dust accumulation is serious, it may even cause excessive load on the pipe support and bring safety hazards. [0003] Therefore, preventing dust accumulation and clogging is an important content that needs to be considered in the design...

Problems solved by technology

In practical application, this method often has the situation that the ash discharge pipe is seriously blocked and cannot be used. Compared with the previous two methods, the maintenance workload is greater, and it is easy to affect the continuous operation of the system, so it is rarely used now.
