Online accumulated dust removal device for dust-gas pipeline

Abstract

The invention relates to an online accumulated dust removal device for a dust-gas pipeline. The device is characterized in that the dust-gas pipeline is horizontally arranged, and the device comprisesa blowing valve group and a blowing pipe, wherein the blowing valve group is positioned above the dust-gas pipeline, an air inlet of the blowing valve group communicates with compressed air through an air supply pipe, and an air outlet is connected with an air guide pip; the blowing pipe is arranged in the dust-gas pipeline, one end of the blowing pipe is connected with the air guide pipe, and the blowing pipe communicates with a plurality of nozzles, and preset angles are correspondingly formed between the plurality of nozzles and the flowing direction of the air in the dust-gas pipeline. According to the online accumulated dust removal device for the dust-gas pipeline, the blowing valve group and the blowing pipe are arranged, the compressed air enters the blowing pipe through pulse airflow, and the compressed air is blown out by the plurality of nozzles, so that dust is blown, the dust flows by means of the flow velocity of smoke in the dust-gas pipeline, and the dust is collectedafter entering a dust remover; and automatic dust removal is achieved, manual dust removal is not needed, online dust removal can be achieved, and the defect that the flow state of the dust-gas pipeline is periodically changed by treating a maintenance period as a period is overcome.

Description

technical field [0001] The invention relates to the technical field of removing dust accumulation in dust gas pipelines, in particular to a device for removing dust accumulation in dust gas pipelines online. Background technique [0002] Due to process requirements, the flow rate of some dust and gas pipelines is changed. When the flue gas flow rate is lower than the self-cleaning flow rate, the dust in the flue gas of the horizontally arranged pipes will be deposited in the pipes. When the pipeline accumulates dust, its flow area will decrease, and the fluid characteristics of the pipeline will change, which will affect the normal production. The current existing and disclosed technical scheme is the passive ash removal method. In order to solve the problem of ash accumulation, after the ash accumulation in the general pipeline reaches a certain level, the ash accumulation in the pipeline will be manually removed during the maintenance period of the production line. Manu...

AI Technical Summary

Problems solved by technology

Manual cleaning is labor-intensive, the working environment is harsh, and manual cleaning is easy to cause environmental pollution

Moreover, the flow characteristics of the pipeline change periodically with a maintenance period as the cycle. The later the maintenance period, the greater the resistance of the pipeline, which is not conducive to process production
