Problems solved by technology

4. Coal dust falls on mechanical and electrical equipment, which will greatly shorten the service life of the equipment, and the environmental sanitation of the work area also requires more manpower and material resources for maintenance
At present, in view of the large amount of dust generated during unloading, conveying and crushing of coal with poor coal quality, the effect of the existing dust suppressants on the market is not ideal

Embodiment 1

[0010] ①Prepare the wetting foam dust suppressant first, add 70% isooctylphenol decapolyoxyethylene ether TX100, add 10% sodium dodecylbenzene sulfonate LAS and 10% calcium chloride, then add 10% Glycerin is mixed with the wetting foam dust suppressant of the present invention; 2. the prepared wetting foam dust suppressant is dissolved in water, mixed and stirred evenly to form a 20% concentrated aqueous solution; 3. the 20% concentrated aqueous solution is put into dust removal in proportion In the water tank sprayed by the nozzle, make the water in the water tank a dilute aqueous solution with a concentration of 0.03%. ④ The dilute aqueous solution with a concentration of 0.03% is transported by the pipeline system (required water pressure ≥ 5kg) and sprayed out through the atomizing nozzle to form fine mist particles. After a reasonable arrangement of multiple nozzles and a reasonable combination of nozzle actions, the nozzle spray The formation sequence of the water mist a...

Embodiment 2

[0012] ①Prepare the wetting foam dust suppressant, add 25% isooctylphenol decapolyoxyethylene ether TX100, add 10% alkyl glycoside APG, add 15% fatty alcohol polyoxyethylene ether AEO, add 15% coconut oil fatty acid di Ethanolamide 6501 adds 20% sodium dodecylbenzene sulfonate LAS and 10% magnesium chloride, and then adds 5% ethylene glycol to mix the wetting foam dust suppressant of the present invention; ② the prepared wetting foam dust suppressant Dissolve the agent in water, mix and stir evenly to form a concentrated aqueous solution with a concentration of 30%; ③Put the concentrated aqueous solution with a concentration of 30% into the water tank sprayed by the dust removal nozzle in proportion, so that the water in the water tank becomes a dilute aqueous solution with a concentration of 0.05%. ④ The dilute aqueous solution with a concentration of 0.05% is transported by the pipeline system (required water pressure ≥ 5kg) and sprayed out through the atomizing nozzle to for...

Abstract

The invention belongs to the technical field of chemical dust suppression, and particularly relates to a wetting foam dust-suppression method used in the fields and places where the dust is generated easily. The wetting foam dust-suppression method comprises the following steps: 1, uniformly mixing and stirring a nonionic surfactant, an anionic surfactant, a hygroscopic inorganic salt coagulant and a co-emulsifier in proportion, and preparing a high-concentration aqueous solution with the concentration of 20%-35%; step 2, placing the high-concentration aqueous solution in the step 1 proportionally into a water tank for a dust removal nozzle to spray, and enabling water in the water tank to become a dilute aqueous solution with the concentration of 0.03-0.05; and step 3, delivering the dilute aqueous solution in the step 2 by a pipeline system (the required hydraulic pressure is larger than or equal to 5kg) and spraying the solution by atomizing nozzles to form subtle spray particles, and enabling the water mist sprayed from the nozzles to form sequential and laminated regions covered with a great amount of atomized foam after reasonable arrangement of a plurality of nozzles and reasonable combination of nozzle actions. The vast majority of the dust in the atomized foam covered regions is adsorbed to the foam, other part drops along with water mist, so that ideal dust suppression effect is achieved.

Description

[0001] The invention belongs to the technical field of chemical dust suppression, and specifically refers to a wet foam dust suppression method, which is used in fields and places where dust is easily generated. Background technique [0002] Dust exists in every corner of our real life, mainly from material transportation (such as: coal), long-term storage (such as: coal), road cleaning and dust treatment, etc. Coal is the main energy source for thermal power plants, power plants, coking plants, cement plants and other factories and mines, especially it accounts for more than 60% of the cost of the entire power plant. With the reform of my country's power system, the power market is developing towards marketization. Control and economic operation will be the focus of major companies in the future, coupled with the current domestic environmental protection department's policies to control SOx, NOx and particulate matter emissions and the structural changes in the coal industry, f...
