No filter element mobile dust removal equipment

Abstract

The invention discloses a mobile dedusting device without a filter element. The mobile dedusting device without a filter element includes a chassis, a main gas storage pipe, a fan, a cyclone group, a main air inlet pipe, a water supply device, and a spray device; the chassis There is a walking structure on the top; one end of the air inlet main pipe is connected to the air inlet of the fan; the fan is fixed on the chassis through a bracket; one end of the air storage main pipe is connected to the air outlet of the fan, and the other end is closed The cyclone group includes several cyclones, the inlet of each cyclone communicates with the gas storage main pipe through the extension pipe, and the lower outlet is set downward; the water supply device is connected with the spraying device through a pipeline with a water pump, For supplying water to spray installations.

Description

technical field [0001] The invention relates to the field of dust removal equipment, in particular to a mobile dust removal equipment without filter elements. Background technique [0002] For dust removal in construction tunnels and narrow, long, closed and semi-enclosed spaces (the following tunnels are used as examples), the dust and haze are usually discharged out of the tunnel by fan supply, or the dust haze is pumped out of the tunnel by ventilation shaft fans, but these two methods Dust removal for long (more than 10,000 meters) large tunnels in the mountains is a difficult problem to solve. It takes too long to discharge the dust and haze, which wastes a lot of construction time and seriously affects the construction progress. At present, there is a dust removal system that uses the principle of filtration in long tunnels: the dirty air in the tunnel is sucked in by the fan, and filtered through the filter element to achieve the purpose of dust removal. But as of no...

AI Technical Summary

Problems solved by technology

[0003] 1. The dust and haze of the construction tunnel is heavy and constantly generated;

[0004] 2. The use time of the filter element is limited, and the filter element needs to be cleaned or replaced after several construction cycles, and the cost of use is high;

[0005] 3. Unable to remove PM2.5 (the most harmful dust haze to the human body) to a qualified level;

[0006] 4. Unable to remove harmful substances such as sulfides and phosphides that are water-soluble and harmful to the human body
