Dust-containing pipeline structure capable of effectively solving dust accumulation in pipe and design method thereof

Abstract

The invention discloses a dust-containing pipeline structure capable of effectively solving dust accumulation in a pipe and a design method thereof. The design method of the dust-containing pipeline structure comprises the following steps of: 1) testing and determining an angle of repose alpha under a static condition of collected dust; 2) designing a vertical auxiliary collecting pipe connectedwith a horizontal main pipe in a dust removal collecting system into a folded pipe type, specifically comprising a first vertical auxiliary collecting pipe into which airflow enters, a second verticalauxiliary collecting pipe connected with the horizontal main pipe and a folded pipe connected between the irst vertical auxiliary collecting pipe and the second vertical auxiliary collecting pipe, wherein an included angle delta is formed between the folded pipe and the horizontal plane; 3) ensuring that the included angle delta is greater than a+5 degrees; and 4) installing a butterfly valve in the first vertical auxiliary collecting pipe. The dust-containing pipeline structure capable of effectively solving dust accumulation in the pipe and the design method thereof provided by the invention solve the problem that the original pipeline cannot be opened because the valve is pressed completely by accumulated dust, which causes serious blockage and leads to dust collection failure at thecollection point. The improved folded pipe has no dust accumulation phenomenon, and the valve is smoothly opened, convenient to clean, and the pipeline has no blockage, which can effectively collectdust in time.

Description

technical field [0001] The invention belongs to the technical field of industrial waste gas dedusting, and in particular relates to a dust-containing pipeline and a design method thereof which can effectively solve the accumulation of dust in the pipeline. Background technique [0002] In the process of industrial production, the dust treatment in industrial waste gas mainly adopts the process of "dust removal". In order to effectively capture dust and reduce operation and maintenance costs, the dust removal facility site usually adopts multi-point capture and negative pressure inside the dust removal facility. And set dust collection pipes and hoods at the points to be caught to capture and collect the dust on the spot. Due to the long production line on the dust removal and capture site, adjustment changes and differences in production conditions, huge collection points and complex negative pressure capture pipe network and control system are often involved. The vortex ar...

Problems solved by technology

Due to the long production line on the dust removal and capture site, adjustment changes and differences in production conditions, huge collection points and complex negative pressure capture pipe network and control system are often involved. In the process of dust collection pipe network mechanical structure design, horizontal The airflow vortex area is easy to be generated at the junction of the pipeline and the vertical auxiliary collection pipe, causing the dust to sink to the vertical auxiliary collection pipe and form accumulation in some places inside the vertical auxiliary collection pipe. Once the dust accumulation forms a certain amount If the pipeline valve is crushed, it will be difficult to open it again, and the local dust point capture effect will be formed. This invention provides a method in the design of high dust pipeline, and then effectively solve the problem caused by this design defect.
