Air supply column for dust control device and dust control device comprising air supply column

Abstract

The invention discloses an air supply column for a dust control device and the dust control device comprising the air supply column. The air supply column for the dust control device comprises a columnar body, an air outlet frame and air guiding blades; an air supply groove extending in the length direction is formed in the peripheral wall of the columnar body; the air outlet frame is arranged onthe peripheral edge of the air supply groove in a surrounding manner and extends outwards in the direction perpendicular to the peripheral edge of the air supply groove; the multiple air guiding blades are arranged in the air outlet frame in the length direction of the air outlet frame in a spaced manner; and each air guiding blade comprises a first extending section and a second extending sectionconnected with the first extending section, the first extending section extends downwards in the horizontal direction, the first preset included angle beta is formed by the first extending section and the axis of the columnar body, the second extending section extends upwards in the horizontal direction, the second preset included angle gamma is formed by the second extending section and the horizontal direction, beta is larger than or equal to 20 degrees but smaller than or equal to 25 degrees, and gamma is larger than or equal to 20 degrees but smaller than or equal to 25 degrees. The air supply column for the dust control device is simple in structure, the produced air flow is stable and low in skewness, and size miniaturization of the dust control device can be realized.

Description

technical field [0001] The invention relates to the field of dust cleaning technology for quickly isolating and collecting dust sources that are open or cannot be fixed and sealed, and in particular to an air supply column for a dust control device and a dust control device with the same. Background technique [0002] Open dust sources are divided into scattered dust sources, large quantities, and large total emissions, requiring various collection and purification equipment. There is an existing type of dust source that cannot be fixed and sealed, and the dust diffuses seriously, which greatly affects the health of workers and the cleanliness of the production workshop. At present, there is no effective technology for rapid isolation and collection. [0003] Existing dust isolation and collection technologies mainly include: fume hood dust collection technology, air curtain dust isolation technology, rotating air curtain dust collection technology, etc. [0004] Among them...

AI Technical Summary

Problems solved by technology

However, in the prior art, due to the impact of the deflected jet air curtain stroke on the fixed platform, the flow form of the airflow in the air curtain sealed space will be disturbed, and the performance of the air curtain generator will be unstable, with high dispersion and large deflection. The problem that affects the collection efficiency

Moreover, the air curtain generating device of the existing rotary air curtain dust collection device has a large volume, which is not suitable for the working environment with strict restrictions on the volume.

In addition, the overall size of the existing rotary air curtain dust collection device is usually: 1m×1m×1 m (length×width×height), which cannot meet the needs of large-sized dust collection devices
