Embodiment Construction

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0034] Such as figure 1 As shown in the present invention, the device for removing dust on-line in the dust gas pipeline, the dust gas pipeline 1 is horizontally arranged, and one end is the air inlet end, and the other end is connected to the dust collector. The device includes a blowing valve group 2 and Injection pipe 3. The blowing valve group 2 is located above the dust gas pipeline 1, the air inlet of the blowing valve group 2 communicates with the compressed air through the air supply pipe 21, and the air outlet is connected with an air guide pipe 4, and the air guide pipe 4 Extending downwards into the dust-gas pipeline 1; the blowing pipe 3 is arranged in the dust-gas pipeline 1 along the length direction ...

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...
