Method and equipment for suppressing dust with dry mist

Abstract

The invention relates to a method and equipment for suppressing dust with dry mist. The method for suppressing dust with dry mist is characterized in that a plurality of atomizing nozzles are arranged in parallel on a disorderly discharged dust drift outlet of a dust generation point and are used for spraying the dry mist having the particle size of less than 10 Mum and making the sprayed dry mist form into a dry mist curtain to prevent the dust generated in the dust generation point from diffusing outwards to pollute the environment. The equipment for suppressing dust comprises a water supplying pipeline, an air supplying pipeline, an air compressor, an air storage tank and a control box. The air supplying pipeline, the water supplying pipeline and an electrical control pipeline which are led out of the control box are respectively connected with the air inlets, the water inlets and tracing band inlets of the atomizing nozzles which are arranged in parallel. The micro-size dry mist is sprayed to form a dry mist curtain to suppress dust. The micro-size dry mist spraying system equipment adopts the air compressor to supply compressed air, and the water and the air enter the atomizing nozzles in two branches. The micro-size dry mist spraying system equipment has simple structure, low running cost, wide application range and good dust suppression effect, consumes less water and works stably and reliably.

Description

technical field [0001] The invention relates to a dry fog dust suppression method. The invention also relates to equipment used in the dry fog dust suppression method. Background technique [0002] During the processing, loading and unloading and transportation of some materials such as coal and ore, serious dust will be generated. The dust drifting with the air will not only cause environmental pollution, but also lead to material loss. At present, for the control of the above-mentioned dust with the characteristics of unorganized emission, the water spray dust removal method is mostly used. The water spray dust removal method is to install a water mist nozzle around the dust generation point of the fugitive emission, and spray water mist to the dust generation point through the nozzle to cover the dust. materials, for dust suppression. Its water spray dust removal method is based on the principle of spraying water at the dust point to increase the humidity so that the du...

AI Technical Summary

Problems solved by technology

Its water spray dust removal method is based on the principle of spraying water at the dust point to increase the humidity so that the dust will no longer rise. Due to the complex environment at the dust point, it is difficult to increase the humidity to make the operating materials no longer dusty. Spraying humidity will also increase the moisture content of the material, especially for water-sensitive materials, which will have a serious negative impact

At present, the equipment used for water spray dust removal is generally a high-pressure water pump system equipped with a water mist nozzle. The principle of water spray is to pressurize the waterway of the system pipeline, and spray water out of the pipeline with water pressure, and the wate
