Problems solved by technology

Although magnetic field magnetization can enhance the wetting and dust-reducing performance of aqueous solution, most of the existing magnetizers are mainly used in the field of water purification treatment, and do not use the improvement of solution wetting performance as a technical evaluation index, such as patents CN201310377032.9, CN200810172164.7, and the above patents The magnetization devices generally adopt a straight-through magnetization structure and a single-direction magnetization mode, which easily leads to unbalanced magnetic field strength and unstable operation, and cannot effectively improve the wetting performance of the solution, and cannot effectively improve the wetting performance of the spray dust suppression water.

Abstract

The invention discloses a magnetization device and method for preparing magnetized water for falling dust in a coal mine. It consists of a magnet, an internal magnet, a hollow pressure-resistant tube, a spiral blade, a magnetic shield, a connecting steel column, a pressure-resistant tube, a closing nut and a flange. The invention adopts an alternate arrangement method to arrange the inner and outer magnets on the water flow spiral channel formed by the hollow pressure-resistant tube, the spiral blade and the pressure-resistant tube, and constructs a high-efficiency magnetization environment combining pulsating cutting magnetization and spiral turbulence , so that the flowing dust water can be continuously and efficiently magnetized, and the turbulence and magnetic path of the water flow can be increased, so as to avoid the problem of not getting uniform magnetization due to the short contact time between water and the magnetic field. The device is inherently safe, easy to operate, and compact Small size and high magnetization efficiency. It is suitable to be placed in various places underground in coal mines, and can effectively improve the wetting performance of dust suppression water.

Description

technical field [0001] The invention relates to the field of mine dust removal technology and equipment, in particular to a magnetization device and method for preparing magnetized water for coal mine dust removal. Background technique [0002] Coal is the main energy source in our country. However, 95% of coal mines in my country are underground operations. With the continuous improvement of mining mechanization, the amount of dust generated underground in coal mines is also increasing. Especially in the production process of mining face, the dust concentration is often as high as 2000mg / m 3 More than, the physical and mental health of underground workers and the safe production of mine cause great threat. At present, the dust suppression measures commonly used in underground are mainly water spray dust suppression technology, such as coal seam water injection, high-pressure spray, etc., but due to the high surface tension of water itself and the high hydrophobicity of co...
