Dusty gas medium pipeline automatic cleaning system and method

Abstract

The invention discloses a system for automatically cleaning dust in a dusty gas medium pipeline. The system comprises more than one dust collecting conical funnels arranged on a dusty gas pipeline, as well as an electric dust cleaning valve, a filter and a vacuuming system arranged on the outlet of each dust collecting conical funnel, wherein each electronic dust cleaning valve is connected with the filter and the vacuuming system through a dust cleaning pipeline in sequence; the system further comprises an automatic control system for controlling the electronic dust cleaning valve, the filter and the vacuuming system to work. The invention further discloses a method for automatically cleaning dust in the dusty gas medium pipeline, and according to the method, the dust is cleaned by using the vacuum and the pressure difference. The system and the method for automatically cleaning dust in the dusty gas medium pipeline, disclosed by the invention, are applicable to gas medium pipelines with fine powder grains, difficult to stick, water-free and dry, the energy consumption can be reduced, the maintenance is convenient, the dust cleaning effect is good, and the environment pollution is reduced.

Description

technical field [0001] The invention belongs to the field of cleaning pipeline systems, and in particular relates to an automatic dust-cleaning system and method for pipelines of dusty gas medium. Background technique [0002] In the industrial field, for dusty gas medium pipelines such as flue gas pipelines, gas pipelines, etc., during the medium transportation process, it is easy to accumulate dust on valves, elbows, tees, low points of pipelines, etc. Currently, the commonly used methods for cleaning pipelines are: Compressed gas purging, high-pressure water flushing, manual dust removal, etc. [0003] The compressed gas purging method is usually to reserve purge joints and ash outlets at intervals on the dusty gas medium pipeline. When cleaning the ash, the compressed air is introduced to blow the accumulated ash to the ash discharge port along the flow direction of the medium. Disadvantages and deficiencies of this method: a. During purging, the dust is relatively lar...

AI Technical Summary

Problems solved by technology

Disadvantages and deficiencies of this method: a. When purging, the dust is relatively large at the ash outlet, causing secondary pollution to the environment; b. When the diameter of the dust-laden medium pipe is large, the flow rate of the compressed gas is slow, and the cleaning effect is not good. Better, if the purge joint and compressed gas flow are increased, the consumption of media will be increased, and the operation and maintenance costs will be increased

Disadvantages and deficiencies of this method: a. During ash cleaning, the flushing water and accumulated ash form mud, which is difficult to collect and easily causes secondary pollution to the environment; b. After flushing, the pipeline needs to be purged and dried, which increases maintenance costs and time

Disadvantages and deficiencies of this method: a. The working environment is harsh and the labor intensity of the workers is high; b. Since the operation is in a confined space, and the dust-containing medium is usually toxic and harmful gas, the workers are likely to cause occupational hazards such as suffocation and poisoning
