Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems of poor dust removal effect and difficulty in reaching national emission standards in the prior art when industrial boilers discharge smoke and dust, and to provide a dust removal modifier for efficiently capturing, adsorbing and removing smoke and dust. The modifier has a high-efficiency effect on the capture and adsorption of smoke dust. The components of the modifier play their own special effects with different ratios and different functions, and the components interact to achieve high-efficiency capture, adsorption, wrapping, Dust removal effect of precipitation

Embodiment 1

[0009] Example 1: A dust removal modifier that efficiently captures, absorbs, and removes soot. The dust removal modifier of this embodiment is suitable for the limestone gypsum method spray dust removal and desulfurization process. Specifically, the modifier of this embodiment is added to the diluted In the limestone solution, the amount added therein is to add 25g of the modifier of this embodiment for every ten tons of water according to the weight ratio. Polyoxyethylene ether 8g, lauryl dimethyl amine oxide 2.5g, alkyl polyglucoside 4g, anhydrous aluminum potassium sulfate 3g, fatty alcohol polyoxyethylene ether 2.5g.

Embodiment 2

[0010] Example 2: A dust removal modifier that efficiently captures, absorbs, and removes soot. The dust removal modifier of this embodiment is suitable for the process of double-alkali desulfurization and dust removal. Specifically, the modifier of this embodiment is added to the circulating water pool for dust removal and desulfurization Within the period, regular maintenance can be carried out according to the circulation cycle of the enterprise's circulating water. The amount to be added is 30 g of the modifier of this embodiment for every ten tons of water according to the weight ratio. 9g, 2.4g of dodecyl dimethyl amine oxide, 3g of alkyl polyglucoside, 4.5g of anhydrous aluminum potassium sulfate, 3.6g of fatty alcohol polyoxyethylene ether.

Embodiment 3

[0011] Example 3: A dust removal modifier that efficiently captures, absorbs and removes smoke and dust. The dust removal modifier of this embodiment is directly used for dust removal spraying. Specifically, the modifier of this embodiment is directly added to water for spraying, wherein the added The amount according to the weight ratio is to add 28g of the modifier of this embodiment for every ten tons of water, and the specific proportion of each component in the modifier is as follows: 4.2g of sodium secondary alkyl sulfonate, 9.8g of hydroxy synthetic alcohol polyoxyethylene ether , 4.2g of dodecyl dimethyl amine oxide, 5.6g of alkyl polyglucoside, 2.8g of anhydrous aluminum potassium sulfate, 1.4g of fatty alcohol polyoxyethylene ether.

Abstract

The invention discloses a dust-removing modifying agent capable of efficiently capturing, adsorbing and removing smoke dust. The modifying agent is prepared from the following components in percent by weight: 15-25% of secondary-alkyl sodium sulfate, 30-35% of hydroxy synthetic alcohol polyoxyethylene ether, 8-15% of dimethyl dodecyl amine oxide, 10-20% of alkyl polyglycoside, 10-15% of anhydrous potassium aluminum sulfate and 5-15% of fatty alcohol-polyoxyethylene ether. According to the dust-removing modifying agent, the surface acting force can be reduced to be a quarter of that of common substances; the surface wet strength and the capturing and adsorption capability are improved; hydrophilic groups on the surfaces of the substances can be efficiently combined with dust grains in the smoke dust, so that the hydrophilic groups can be rapidly wetted, covered, adsorbed and settled; and the viscidity of molecule surfaces can be improved so that the smoke dust is stuck when being in contact with the surface of liquid, and is not easy to separate from liquid components at a high temperature, and furthermore, smoke dust molecules are prevented from escaping after being adsorbed. The dust-removing modifying agent is environmentally friendly, has the very high stability under strong-alkali and strong-acid environments and weak-acid and weak-alkali environments, and is applicable to various working conditions.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal, in particular to a dust removal modifier for efficiently capturing, adsorbing and removing smoke and dust. Background technique [0002] Since the 12th Five-Year Plan, the country has continuously raised the emission standards for boilers such as coal-fired boilers and biomass power plant boilers. The smoke and dust are treated to about 20 mg / standard square. Recently, the state will introduce ultra-low emission standards for flue gas from coal-fired and biomass-fired boilers, and raise the flue gas emission standard to below 5 mg / standard square. Enterprises that fail to meet the standards will be ordered Rectification or shutdown, so how to remove the smoke and dust in the flue gas has become a top priority for enterprises. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of poor dust removal effect and difficulty in reaching n...
