Abstract
The present invention discloses a raise dust inhibitor with a function of catalyzing coal combustion and a preparation method thereof, and is dedicated to water vapor absorption components for coal storage sites of thermoelectric enterprises. The raise dust inhibitor consists of the following components in percentages by weight: 20-30% of catalytic combustion components, 20-30% of water vapor absorption components, 1-2% of soaking and wetting components, and the balanced being water. By spraying the products on coal yards, the raise dust inhibitor can maintain significant dust inhibition effects within 30 days. After spraying the products, during the combustion of the coal and under the effects of the catalytic combustion components, the raise dust inhibitor can at the same time realize the effect of reducing the coal consumption.
Description
Technical field
The invention belongs to energy-conserving and environment-protective technical fiel, more particularly to a kind of airborne dust to coal with catalysis combustion function presses down
Preparation.
Background technology
China is the energy resource structure based on coal electricity, and domestic each place all has substantial amounts of Thermal Power Enterprises, single fire at present
Electric enterprise is owned by the large-scale indoor coal storage yard or coal open storage ground of oneself.With the passage of coal storage time, coal progressively wind
Change, efflorescence, ultimately cause dust pollution.
Fugitive dust inhibiting agent primarily occur ins the countries such as English, U.S., and with progressively tightening up for Environmental Protection in China requirement, the country was in recent years
Start such product occur.Domestic existing Fugitive dust inhibiting agent technology, is film forming Fugitive dust inhibiting agent, i.e., by modified starch
Deng material, one layer of solid film is formed to reach the purpose for suppressing to form by being covered in dust surface.Such as Chinese patent
CN201410257710.2, is sprayed on product coal, Hui Chang surfaces can be made to form one layer of cured film at miberal powder accumulation, to reduce
The pollution and airborne dust loss in storage, transportation to surrounding enviroment such as coal, miberal powder.
As Chinese society develops, environment protection requirement is necessarily improved year by year.In view of China's fire coal contact scar weather is tight
High property, cleaning for coal is further urgent using requiring.
The content of the invention
In order to overcome the shortcomings of the presence of prior art, primary and foremost purpose of the invention is to provide a kind of with catalysis coal
Fugitive dust inhibiting agent of combustion and preparation method thereof.
The purpose of the present invention is achieved through the following technical solutions：A kind of airborne dust with catalysis coal burning effect suppresses
Agent.The Fugitive dust inhibiting agent is made up of the component of following part by weight：Catalysis combustion components 20~30%, water vapor absorption group
Divide 20~30%, be impregnated with moistening components 1~2%, water for surplus.Wherein, above-mentioned catalysis combustion components are lanthanum acetate and acetic acid
Cerium, weight ratio is 1:1；The water vapor absorption component is MW=800~1000 modified HPMA and MW=1000~
One kind of 2000 beta cyclo dextrin polymers or its mixture；The moistening components that are impregnated with are for the fast T in commercial surfactant.
Present invention also offers the preparation method of above-mentioned Fugitive dust inhibiting agent, comprise the following steps：(1) add in enamel still
Enter the water of surplus, be warming up to 70 DEG C；(2) then under agitation, it is slowly added to be catalyzed combustion components, stirring is to complete molten；(3) stir
Lower addition water vapor absorption component, keeps being stirred 20-40 minutes at a temperature of 70 DEG C of system；(4) it is eventually adding and is impregnated with moistening components
Afterwards, stir 0.5-1 minutes and stop.
It is of the invention compared with existing Fugitive dust inhibiting agent technology, its significant advantage is：(1) Fugitive dust inhibiting agent of the invention
Not only there is good suppression airborne dust to act on to the dump in Coal Yard, while having the effect of catalysis burning, energy to coal
Enough beginning burning-points and all burnt for substantially reducing coal.(2) the Fugitive dust inhibiting agent mechanism of action of the invention is different from existing commercially available
Fugitive dust inhibiting agent, i.e., by dust surface cure membrane formation mechanism.Water vapor absorption component of the invention can be with absorption air
Steam, and moisture is latched in intramolecule for a long time, keep the wet of dust surface in the case where moistening components synergy is impregnated with
Profit, prevents airborne dust from occurring.
