Automatic spraying and dust-preventing method, and dust-preventing apparatus

Abstract

The invention relates to an automatic spray device for blocking dust, including an automatic induction mechanism, a spray mechanism, a spray control mechanism and a dust suppression mechanism; the spray mechanism controls the spray mechanism by the induction signal of the automatic induction mechanism. The invention also provides an automatic spray dust blocking method; the automatic induction mechanism induces environmental parameters and sends the induction signals of the environment parameters to the spray control mechanism, according to the induction signals the spray control mechanism sends instruction to control the spray mechanism to spray or stop spaying fluid to the dust suppression mechanism and / or a material heap. The automatic spray device can realize full automatic management or adopt manual management, thus having convenient use, obvious effect and being capable of treating the pollution problem caused by aeolian erosion and dust emission from working surfaces; meanwhile, the automatic spray device can achieve the functions of auto-regulation, spraying, water conservation, self cleaning, waterproof property, dust collecting, and so on according to the external environment.

Description

Technical field: [0001] The invention relates to a dust suppression method and a dust suppression device, more specifically, to a dust suppression method and a dust suppression device by using an automatic spraying method. Background technique: [0002] The invention is mainly applicable to the field of environmental protection, and is especially suitable for reducing dust in places such as coal piles, stockyards, docks, tailings ponds and the like. With the rapid development of my country's economic construction, various stockyards and coal piles are scattered all over the place. Taking coal storage plants as an example, there are more than 6,000 coal storage plants, of which 1,700 are more than 50,000 tons, and most of them are stored in the open air, lacking dust prevention, dust suppression and dust collection equipment. According to the report "Research on the Environmental Impact of China's Coal Development and Utilization" by the Clean Energy and Environment Center o...

Problems solved by technology

However, due to manual control, it is difficult to grasp the spraying amount at that time and in the local area, which can easily lead to insufficient water and poor dust suppression effect; or due to excessive water and runoff, the fine coal surface is mixed into the surrounding environment, which consumes both manpower and time. wasting precious water resources

In the Chinese patent CN02147666.7 "A method for preventing wind and desert with vertical nets", a method for preventing desertification with vertical nets is disclosed, but it only uses physical barriers and does not have any other self-control dust suppression facilities, and because the height of the net is too low, it can only prevent the surface runoff; and in the Chinese patent CN01239861.6 "A wind-reducing sand filter net that can reduce wind speed and filter flying sand", the vertical net is also for For desert control, and the gap between the horizontal extension lines of the net is too small, it is required to be less than 0.41mm. While the wind reduction effect occurs, the wind resistance on the actual net will greatly increase, and the requirements for support facilities will increase, and at the same time This net is not equipped with self-controlled sprinkler equipment
