A secondary filter and absorption equipment for industrial gravel dust

Abstract

The invention discloses a secondary filter and absorption equipment for industrial crushed stone dust, which includes a dust absorption box, a dust storage box, a deposition conveyance and a support frame; the dust absorption box is installed above the primary filter box, and the primary filter box is installed on the Above the support frame, the dust storage box and the support frame are arranged side by side. A secondary filter box is installed above the dust storage box. The secondary filter box and the primary filter box are connected through the secondary filter inlet and the primary filter outlet. The primary filter box A blower is installed on the side opposite to the secondary filter box, the bottom of the primary filter box is provided with a first-stage dust outlet, and a collection box is provided below the first-stage dust outlet, and the first-stage dust outlet and the collection box are arranged inside the support frame; the present invention Utilizing the guiding effect of wind force on the flow of dust, the dust is filtered through two stages and deposited twice, and the dust of different sizes is treated separately, which will not cause a large amount of dust accumulation to the dust treatment equipment, so as to completely purify the dust.

Description

technical field [0001] The invention relates to the technical field of fugitive dust treatment and absorption, in particular to secondary filtration and absorption equipment for industrial crushed stone fugitive dust. Background technique [0002] Flying dust, as the primary source of air pollution to be controlled now, has been highly valued by various enterprises. Only water mist can be sprayed on construction sites to suppress the volatilization of fugitive dust. Enterprises are constantly innovating the treatment technology of fugitive dust in order to achieve better Control effect. [0003] At present, the treatment of fugitive dust mainly depends on the way of water curtain, water mist and filter screen to settle the dust. The water mist and water curtain are not suitable for equipment that cannot have water in the production process, such as firing or crushing, and industrial gravel. It is not suitable for water mist. Wet gravel is unfavorable to the later production...

Problems solved by technology

[0003] At present, the treatment of fugitive dust mainly depends on the way of water curtain, water mist and filter screen to settle the dust. The water mist and water curtain are not suitable for equipment that cannot have water in the production process, such as firing or crushing, and industrial gravel. It is not suitable for water mist. Wet gravel is unfavorable to the later production. Usually, the gravel is made of a filter with air permeability to block the dust from the outside air. When a large amount of dust gathers and absorbs each other, it will produce After enough weight, it starts to sink. This method usually requires a long dust removal pipe, otherwise a large amount of powder will fall back to the parts of the equipment or the surrounding time will be long and cause blockage, which will affect the normal use of the equipment. The connection mechanism is not strict enough. It will also cause secondary pollution to the air
