Wet dust removal and wind speed spraying haze-removing and dust-settling fan

Abstract

The invention discloses a wet dust removal and wind speed spraying haze-removing and dust-settling fan which comprises the following parts of a wet dust removal fan, at least one first spraying device, an air collection device and an air inlet device, wherein the air inlet device, the wet dust removal fan and the air collection device are sequentially communicated; the first spraying device is communicated with the air collection device. According to the wet dust removal and wind speed spraying haze-removing and dust-settling fan, the high-pressure purified air discharged by the wet dust removal fan is taken as an air source for wind speed spraying under the condition that the installed power of the fan is not increased, and the water mist is sprayed onto the cross section of a whole roadway along the reverse direction by the high-pressure wind speed of the dust removal fan. Particularly, the wet dust removal and wind speed spraying haze-removing and dust-settling fan can be arranged on a heading machine and is taken as a movable wet dust removal and wind speed spraying dust-settling device; the backward spreading of the dust in the roadway is sealed by the high-speed water mist, so that a satisfactory effect is achieved in the aspects of removing and settling the dust. The device is simple in structure, lower in investment cost, wide in application scope and obvious in energy-saving effect.

Description

technical field [0001] The invention relates to the technical field of ventilation, dust removal and dust reduction equipment, in particular to a wet dust removal and wind speed spray haze removal fan. Background technique [0002] At present, metallurgy, mining, and coal mine underground excavation and mining working faces are all places where a large amount of dust is generated, especially the working face where roadheaders are used. A large amount of dust not only seriously affects the physical and mental health of employees, but also pollutes the surrounding air, endangering the safety of coal mines. Production leaves hidden dangers. In the tunneling of coal mines, the commonly used dust removal methods mostly use filter-type dust removal fans or mine extraction local fans and dust collectors to form wet dust removal fans, and KCS series wet dust removal fans to filter dust and purify the air on the working surface. However, these current types of dust removal fans ha...

AI Technical Summary

Problems solved by technology

However, these current types of dust removal fans have the following disadvantages: 1. In roadways with roadheaders, the dust collection range of the dust removal fans is relatively small, and most of them are concentrated in the middle of the roadheaders. Although they can effectively collect part of the dust in the middle of the roadway, roadheaders cannot A large amount of dust on both sides still spreads backward along the roadway, which may easily cause dust to exceed the limit and pose a safety hazard

2. In blast mining roadway, due to the larger section, the collection section of the dust removal fan is smaller, the dust is blown by the headwind of the local ventilation, and spreads rapidly backwards, and the dust removal efficiency drops sharply

3. Especially in the dust-producing operation points with a spacious space, due to the large dust distribution range, the collection effect of the dust removal fan is even less ideal, and the overall dust removal effect on the site is poor

Most of the traditional spray dust suppression uses multiple spray dust suppression nozzles around, the range is narrow, the water, electricity and gas transmission distance is long, the investment is large, and the dust suppression effect is poor
