Problems solved by technology

Based on the problem of dust control, the application of dust suppression technology has gradually shifted to big cities, mainly to solve the problem of flying dust in open areas such as construction work surfaces, road surfaces, coal yards, and ash storage yards. The initial method to reduce dust and improve air quality is to sprinkle water Dust prevention measures such as dust suppression and construction site enclosures are used, but the water consumption is huge and resources are wasted. Moreover, the dust prevention period of water spraying dust supp

Embodiment 1

[0024] Embodiment 1 Soil surface spray experiment

[0025] Heat water with a mass of 0.76Kg to 60°C, and then dissolve 0.017Kg of polyvinylpyrrolidone, 0.002Kg of sodium alginate and 0.001Kg of guar gum in water to obtain a mixed solution of the water phase; Add the emulsifier Tween 85 of 0.06Kg in the mixed solution, finally add the salad oil of 0.02Kg, the vegetable oleic acid of 0.05Kg, the glycerol of 0.05Kg, the polyethylene glycol of 0.02Kg and the silica sol of 0.02Kg, in homogeneous Stir in a mixer for 30 minutes, and then get a hydrosol-type dust suppressant after mixing.

[0026] The dust suppressant prepared in this implementation is diluted 300 times with water for spraying, and the spraying soil area is 0.4m 2 , the spray volume is 0.25L / m 2 , under the same conditions, design a control group for spraying water on the soil surface, conduct a wind speed test after 36 hours, and use the difference in soil weight to explain the dust suppression function. The exper...

Embodiment 2

[0027] Example 2 Asphalt Pavement Spraying Experiment

[0028] Heat water with a mass of 32.8Kg to 80°C, and then dissolve 4Kg of polyvinylpyrrolidone, 0.4Kg of sodium alginate and 0.4Kg of locust bean gum in water to obtain a mixed solution in the water phase; then mix the solution in the water phase Add 11.2Kg of emulsifier Tween 85 to the mixture, finally add 4Kg of salad oil, 8Kg of vegetable oleic acid, 8Kg of glycerin, 4.8Kg of polyethylene glycol and 6.4Kg of silica sol, stir in a homogeneous mixer for 30min, After mixing evenly, a hydrosol-type dust suppressant is obtained.

[0029] The dust suppressant prepared in this implementation was diluted 500 times with water and then sprayed on the asphalt pavement of a certain street in Jinan. The temperature of the experimental site was 33°C. The experimental data are shown in the table below:

Abstract

The invention provides a hydrosol type dust suppressant. The hydrosol type dust suppressant comprises, by mass, 1-5% of salad oil, 1-15% of vegetable oleic acid, 3-16% of Tween-85, 3-15% of glycerol, 2-8% of polyethylene glycol, 0.1-0.5% of sodium alginate, 0.1-0.5% of guar gum, 1-10% of silica sol, 1-6% of polyvinylpyrrolidone and 40-76% of water. Chemicals and reagents used in the formula of the dust suppressant are non-toxic and environment-friendly medicines, accordingly the formula design starts from the perspective of the molecular level, dust can be set in layers, and microscopic scientific guidance and macroscopic dust suppression regulation are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a dust suppressant. Background technique [0002] The development of the economy drives the improvement of urban construction and living standards. At the same time, the problem of environmental pollution control needs to be solved urgently, especially air pollution, such as the increase of dust and the increase of harmful gas content in the air. The main factors of dust are: (1) The source of dust is dry, It is easy to oxidize, making the surface particles smaller and powdery; (2) It is in a state of bareness and natural weathering; (3) There is no wind-proof blocking device outside, and it is affected by wind. Common dust is mainly composed of organic particles such as industrial construction dust, mineral particles, dust particles, biological residue particles, and household garbage dust. The amount of dust generated by it is related to various factors, such a...
