Embodiment 1

[0063] In this embodiment, water is selected as the chemical dust suppressant, and the weight values ​​of each index in the first-level evaluation index are respectively set in Step 2: the weight values ​​of dust suppression A, economical B and environmental protection C are 0.60 and 0.10 respectively and 0.30, the corresponding scores of each index are A, B, and C respectively; set the weight value of each index in the secondary evaluation index: the weight value of wet performance A1, moisture absorption performance A2 and adhesive performance A3 are all 1 / 3 , that is 0.33, the corresponding scores of each index are A1, A2 and A3 respectively, the weight value of use cost B1 is 1, and the corresponding score is B1, pH value of chemical dust suppressant solution C1, chemical toxicity C2 and chemical corrosion The weight values ​​of C3 are 0.30, 0.30 and 0.40 respectively, and the corresponding scores are C1, C2 and C3. Determine the total score value of the dust suppression pe...

Embodiment 2

[0065] The difference between this embodiment and Embodiment 1 is that calcium chloride is selected as the chemical dust suppressant.

Embodiment 3

[0067] The difference between this example and Example 1 is that Triton X-100 is selected as the chemical dust suppressant.

Abstract

The invention discloses a comprehensive evaluation method suitable for chemical dust suppressant optimization. The method comprises the steps: 1, determining a comprehensive evaluation index system of a chemical dust suppressant, which comprises a first-level evaluation index, a second-level evaluation index and evaluation parameters corresponding to the second-level evaluation index; 2, setting a weight value of each index in the first-level evaluation index and the second-level evaluation index, and then determining a scoring method of the comprehensive evaluation index system; 3, acquiring evaluation parameter values corresponding to the second-level evaluation indexes, and acquiring score values of the second-level evaluation index and the first-level evaluation index through evaluation calculation; and 4, performing calculating to obtain a dust suppression performance evaluation total score value of the chemical dust suppressant, and evaluating the dust suppression performance evaluation total score value. According to the method, the evaluation performance of the chemical dust suppressant is comprehensively covered by setting the two level of evaluation indexes and reasonably setting the evaluation parameters corresponding to the second-level evaluation index, the evaluation of the dust suppression performance of the chemical dust suppressant is realized by combining and adopting a quantitative scoring method, and the accuracy of an evaluation result is improved.

Description

technical field [0001] The invention belongs to the technical field of evaluation of chemical dust suppressants, and in particular relates to a comprehensive evaluation method suitable for the optimization of chemical dust suppressants. Background technique [0002] Dust pollution is one of the main problems in the field of environmental pollution and occupational health in my country. In recent years, chemical dust suppression technology has been widely developed and applied in the field of dust control. However, the development and optimization of dust suppressants mostly use indoor tests and field applications. assessment method. For example, the patent with the publication number CN110746935A discloses a composite environmental protection dust suppressant made of modified starch, microcrystalline cellulose and maltodextrin. It is tested in the laboratory of the environment; the patent "Ecological Dust Suppressant for Surface Mine Dust Control and Its Preparation Method" ...
