Fog curtain system with high wind resistance and wind resistance method

Abstract

The invention discloses a fog curtain system with high wind resistance and a wind resistance method. The system comprises a fog curtain device, wind curtain devices, a pipeline assembly and a control device, wherein the fog curtain device is used for generating a fog curtain; the wind curtain devices are arranged at the positions adjacent to the fog curtain device and used for generating wind curtains for shielding the fog curtain; the pipeline assembly comprises a water pipe, a first air pipe, a second air pipe and a third air pipe; one end of the water pipe is connected with an external water source, and the other end of the water pipe is connected with the fog curtain device; one end of the first air pipe is connected with an external air source, and the other end of the first air pipe is connected with the fog curtain device; one end of the second air pipe and one end of the third air pipe are both connected with the external air source, and the other end of the second air pipe and the other end of the third air pipe are connected with the two wind curtain devices correspondingly; fluid electromagnetic valves are arranged on the water pipe, the first air pipe, the second air pipe and the third air pipe correspondingly; and the control device is electrically connected with the fluid electromagnetic valves. Under blocking of the wind curtains, the fog curtain is at the breeze level, the normal dust suppression effect within the effective range is achieved, and diffusion pollution of dust is prevented.

Description

technical field [0001] The invention relates to the technical field of dust suppression, in particular to a fog curtain system with high wind resistance and a wind resistance method. Background technique [0002] Dust is one of the main pollutants in key industries with heavy pollution. All kinds of materials will produce dust in the main links of loading, unloading, reloading, transportation, etc., which will pollute the environment and damage human health. The fluid atomized spray can effectively treat Dust is suppressed, and it is widely used in power plants, mines, steel, ports and other industries to control dust. However, the application of fog curtains at the entrances and exits of factories and mines vehicles, the entrance of material sheds, etc., due to the existence of ambient wind such as corridor wind, the fog curtain If the nozzle is blown away just after it comes out, it will not be able to suppress the dust at the entrance and exit gate of the factory and mine...

[0002] Dust is one of the main pollutants in key industries with heavy pollution. All kinds of materials will produce dust in the main links of loading, unloading, reloading, transportation, etc., which will pollute the environment and damage human health. The fluid atomized spray can effectively treat Dust is suppressed, and it is widely used in power plants, mines, steel, ports and other industries to control dust. However, the application of fog curtains at the entrances and exits of factories and mines vehicles, the entrance of material sheds, etc., due to the existence of ambient wind such as corridor wind, the fog curtain The nozzle is blown away just after it comes out, and it can’t play the role of dust suppression on the entrance and exit gate of the factory and mine vehicles, and the gate of the material shed, resulting in the spread of dust pollution

[0003] Through field observations on the application of fog curtain atomizing nozzles at the gates of some iron and steel enterprises, the pressure loss of the fluid during the atomization process is extremely large, resulting in small kinetic energy and low spray speed of the fog curtain particles, and the fog curtain particles themselves are atomized Formed, the unit volume and mass are extremely small, which makes the fog curtain easy to flow, so that when there is an ambient wind, the fog curtain will be blown away. To ensure that this does not happen, one is to increase the fluid pressure. However, due to the huge pressure loss during the atomization process, the cost of supporting facilities for the fluid will increase exponentially. The second is to increase the volume of the spray particles, which will lead to a deterioration of the dust suppression effect, and it is also not suitable for materials that require humidity. Appropriate, the third is to build a windbreak corridor, but the cost is high, and it is often limited by the site, which brings other inconveniences to traffic, and there are few other more effective measures at present
