Liquid membrane dust suppression device

Abstract

The invention discloses a liquid membrane dust suppression device, which is applied to dust inhibition in a solid material manufacturing or transporting process. The device comprises a dust suppression liquid membrane generator and a liquid membrane spray part, wherein the dust suppression liquid membrane generator is provided with a shell; the shell is provided with a dust suppression solution input end, a compressed air input end and a dust suppression liquid membrane output end; the dust suppression solution and the compressed air form a thin-walled fine foam shaped dust suppression liquid membrane through the dust suppression membrane generator; and the liquid membrane spray part is connected to the liquid membrane output end. The dust suppression device also comprises an automatic control part, a remote communication part and a field weather and dust monitoring part, so that the spray quantity of the dust suppression liquid membrane can be automatically adjusted according to the field condition, and remote operation can be realized. According to the device, the dust amount of the field can be reduced by 80 to 95 percent to ensure remarkable effect, and the source of field dust pollution can be effectively controlled before pollution happens, so that not only the environment can be protected, and body health of field operators can be beneficial.

Description

technical field [0001] The invention relates to a liquid film dust suppression device, in particular to a liquid film dust suppression device for suppressing the generation of dust in the process of processing or transporting solid materials. Background technique [0002] In mining, regardless of soft rock or hard rock, the mined rock needs to be processed and screened before it can be used. Generally, two processes of crushing and screening are used for processing, and finally it becomes a product that meets the size and shape specifications. In the recycling of construction waste, construction waste generally includes building materials such as waste concrete and bricks, and the recycling process is basically the same as that of rock, which needs to be crushed, screened and transported. The recycling of electronic waste generally requires crushing and screening before processing. The crushing process is to break large pieces of material into small pieces that meet the req...

Problems solved by technology

Because of the poor adhesion of water and the small amount of water, this method of dust suppression requires the use of a large amount of water resources. It takes about 200-500 liters of water per ton of material to effectively suppress the generation of dust. A certain amount of water needs to be added in every link of processing and transportation to ensure sufficient moisture

The problems brought about by this method are: first, water resources are wasted to a great extent, especially in areas where water resources are not abundant; Finally, materials of different sizes cannot be screened out according to the required size specifications, which will affect the further processing of materials and cause malfunctions; thirdly, the water containing dust will become a secondary pollution to the environment, and secondary treatment is required, especially For example, waste electronic products contain many harmful substances, and water containing such dust is more harmful to the environment than dust.
