Problems solved by technology

However, during the coal storage process (coal mines, docks, industrial enterprises, etc.), a large amount of dust will be generated due to wind erosion, which will not only cause great pollution to the surrounding environment, but also cause a waste of resources
[0003] At present, the control technology for dust in coal yards is mainly based on physical methods, and the following two methods are used to control the dust problem: ① Watering method, the method of watering increases the water content of coal on the surface of coal flow or coal pile surface, and increases the water content of coal. The quality of the particles, so it has a certain dust suppression effect, but the water is evaporated quickly, the effective dust suppression time is short, and the water consumption is high. The thermal efficiency of the boiler, the overall effect is not ideal; ②The effect of dust suppression can be achieved by isolating the incoming wind or changing the direction of the incoming wind through large buildings, such as: windbreak walls and closed coal bunkers, which have a certain effect on dust prevention, but the investment cost is high, and it is easy to Tens of millions or hundreds of millions

Abstract

The invention discloses a windproof and dust-suppressing agent for coal yards and a preparation method thereof. The windproof and dust-suppressing agent for coal yards of the invention consists of xanthan gum, 0.1-0.8 parts of maltodextrin, glycerin Prepared with 3-7 parts of propylene glycol, 0.5-4 parts of polyvinyl alcohol, 1.5-5.5 parts of diethylene glycol, 1.5-2 parts of sodium diacetate, 0.5-1 part of OP-10, and 100 parts of water. The wind-proof and dust-suppressing agent for coal yards of the present invention has good permeability, cohesiveness, and moisture-absorbing and water-retaining properties. It can effectively resist wind erosion when sprayed on coal piles, and has a good dust-suppressing effect. At the same time, the dust-suppressing agent has non-toxic , No pollution, easy to degrade, easy to use and so on.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control, in particular to a coal yard windproof and dust suppressant and a preparation method thereof. Background technique [0002] my country's energy structure is dominated by coal. According to statistics, my country's coal consumption reached 3 billion tons in 2010, and will reach 4 billion tons by 2020. Coal has been the main form of energy consumption in my country in recent decades. However, during the coal storage process (coal mines, docks, industrial enterprises, etc.), a large amount of dust will be generated due to wind erosion, which will not only cause great pollution to the surrounding environment, but also cause a waste of resources. [0003] At present, the control technology for dust in coal yards is mainly based on physical methods, and the following two methods are used to control the dust problem: ① Watering method, the method of watering increases the water ...
