Embodiment 1

[0023] S1. Take 10 parts of vegetable gum and place it in a stirring device, inject 30 parts of water, stir at room temperature at a speed of 120r / min for 10 minutes, and add 2 parts of dispersant while stirring. Vegetable gum is a kind of natural vegetable gum. It is galactomannan, and there are also inorganic elements such as protein, cellulose, water, and a small amount of calcium and magnesium. Plant gum is insoluble in any organic solvents such as ethanol, glycerin, and formamide. Water is the only solvent for plant gum, and plant gum When the glue meets water, it can swell and hydrate to form a high-viscosity sol solution, and its viscosity increases significantly with the increase of powder concentration;

[0024] S2. Add 3 parts of modified cellulose, 4 parts of hydroxypropyl methylcellulose and 1 part of defoamer to the stirring device in step S1, and stir at a speed of 120r / min for 5min at 30°C while stirring While adding an appropriate amount of 0.5 parts of preserv...

Embodiment 2

[0027] S1. Take 15 parts of vegetable gum and place it in a stirring device, inject 33 parts of water, stir at a speed of 120r / min at room temperature for 15 minutes, and add 4 parts of dispersant while stirring;

[0028] S2. Add 5 parts of modified cellulose, 7 parts of hydroxypropyl methylcellulose and 2 parts of defoamer to the stirring device in step S1, and stir at a speed of 120r / min for 10min at 35°C while stirring While adding 0.8 parts of preservatives, a mixed reagent was prepared;

[0029] S3. Concentrating the mixed reagent prepared in step S2 to obtain an industrial dust and solid waste emission reduction coagulation material.

Embodiment 3

[0031] S1. Take 20 parts of vegetable gum and place it in a stirring device, inject 35 parts of water, stir at room temperature at a speed of 120r / min for 20 minutes, and add 5 parts of dispersant while stirring;

[0032] S2. Add 7 parts of modified cellulose, 10 parts of hydroxypropyl methylcellulose and 3 parts of defoamer to the stirring device in step S1, and stir at a speed of 120r / min for 10min at 40°C while stirring While adding an appropriate amount of 1 part preservative, a mixed reagent is prepared;

[0033] S3. Concentrating the mixed reagent prepared in step S2 to obtain an industrial dust and solid waste emission reduction coagulation material.

[0034] When in use, take an appropriate amount of the industrial dust and solid waste emission reduction coagulation material and inject it into the spraying device, and inject an appropriate amount of water so that the content ratio of the material to water is 1:20-1:40, and then use the spraying device to spray the dilu...

Abstract

The invention discloses an industrial dust solid waste emission reduction condensing material. The condensing material is prepared from, by weight, 10-20 parts of vegetable gum, 3-7 parts of modifiedcellulose, 2-5 parts of a dispersing agent, 1-3 parts of a defoaming agent, 0.5-1 part of a preservative, 4-10 parts of hydroxypropyl methyl cellulose and 30-35 parts of water. A preparation method ofthe condensing material comprises the following steps: S1, dissolving the vegetable gum in water, and adding the dispersing agent, S2, adding the modified cellulose, hydroxypropyl methyl cellulose, the defoaming agent and the preservative; and S3, concentrating. The invention relates to the technical field of dust condensing materials. The hydroxypropyl methyl cellulose is added, and makes micropores formed in the surface of a membrane material film formation process, so a netted membrane is formed, the membrane formation area is large at the equivalent dosage, and raw materials are saved; industrial dusts are attached to the membrane material formed by the condensing material, settle on the ground, and cannot diffuse into the atmosphere along with the air, so the dusts are convenient tocollect and treat, the pollution to the environment is reduced, the dust discharge amount of enterprises is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of dust coagulation materials, in particular to an industrial dust solid waste emission reduction coagulation material. Background technique [0002] Industrial dust mainly comes from the mechanical crushing and grinding of solid materials, such as ore dressing, ore crushing in refractory workshops and various grinding processes, mixing, screening, packaging and transportation of powdery materials, such as cement, flour, etc. During the production and transportation process, the smoke and dust produced by the combustion of substances, such as the smoke and dust produced when coal is burned, the oxidation and condensation of the steam produced when the substance is heated, such as the zinc vapor produced in the process of ore sintering and metal smelting, will condense Oxidized into solids, industrial dust has an obvious negative impact on the surrounding atmospheric environment, and the degree of harm is rel...
