Abstract
The present invention relates to a combustion-supporting smoke eliminating agent for coal. The present invention comprises carbinol, ethanol, tween, ether, a nitric acid brine solution and lime milk, wherein during the preparation, the tween is used as an emulsifying agent. First, the nitric acid brine solution and the lime milk are simultaneously emulsified; then, the carbinol and the ethanol are added in the mixture and are emulsified; finally, the ether are added in the mixture and are uniformly emulsified, and a product is the combustion-supporting smoke eliminating agent. When used, the present invention is diluted by 1000 times of water. The present invention has good combustion-supporting and smoke eliminating effects, the coal and coal products mixed with diluent of the present invention saves 35% of the coal during the combustion, and the Regman blackness is lower than 1.5%.
Description
The present invention relates to combustion-supporting smoke-eliminating agent and compound method thereof, more particularly, relate to civilian combustion-supporting smoke-eliminating agent and compound methods thereof such as industry or catering industry, family etc. such as industrial boiler power generation.
Boiler of feeding and civilian coal great majority all are bituminous coal or brown coal etc. now, produce denseer smog during burning, contaminate environment seriously, so people extremely is concerned about how to make and both lighted easily when burning coal, do not produce smog again, but still do not have a kind of ideal combustion-supporting smoke-eliminating agent so far.
The purpose of this invention is to provide a kind of effective combustion-supporting smoke-eliminating agent and compound method thereof.
The inventor works out good combustion-supporting smoke-eliminating agent of a kind of effect and compound method thereof through the research of long period.
The feature of combustion-supporting smoke-eliminating agent of the present invention is that its prescription contains following ingredients (weight part): methyl alcohol 8-20 ethanol 5-20 tween (40,60 or 80 or its mixture) 1-8 ether 0.5-5 nitrate aqueous solution 20-40 milk of lime 20-40
In above-mentioned prescription, nitrate aqueous solution is meant that one or more and water in ammonium nitrate, saltpetre and the SODIUMNITRATE is by nitrate: water=(10-20): the solution of the miscible back of weight ratio (80-90) gained, milk of lime are meant that unslaked lime and water are by CaO: water=(5-20): weight ratio (80-95) mix the back and must emulsion.Self-evident, the also available slaked lime of above-mentioned unslaked lime replaces, but its used in amounts is pressed slaked lime Ca (OH)
2Molecular weight to unslaked lime CaO is 56.08, Ca (OH)
2Molecular weight be 74.08, so Ca (OH)
2: CaO=1.32.Therefore when replacing unslaked lime with slaked lime, its amount ranges should multiply by 1.32 on the basis of former amount ranges.Add again after perhaps being converted to the actual content of CaO.
The feature of the compound method of combustion-supporting smoke-eliminating agent of the present invention is that this method comprises the steps:
(1) preparation nitrate aqueous solution
With one or more and water in ammonium nitrate, saltpetre and the SODIUMNITRATE by nitrate: water=(10-20): weight ratio (80-90) mixes until whole dissolvings;
(2) preparation milk of lime
With unslaked lime or slaked lime and water by CaO: water=(5-20): weight ratio (80-95) mixes, until generating uniform emulsion;
(3) emulsification
Mix until emulsification even with nitrate aqueous solution 20-40 weight part and milk of lime 20-40 weight part tween (40,60 or 80 or its mixture) 1-8 weight part;
(4) in the emulsion of step (3), add methyl alcohol 8-20 weight part and ethanol 5-20 weight part, mix to emulsification even;
(5) in the emulsion of step (4), add ether 0.5-5 weight part, mix to emulsification even.
The product that obtains is combustion-supporting smoke suppressor product of the present invention.
In use, must water combustion-supporting smoke suppressor be diluted about 1000 times, be called combustion-supporting smoke suppressor diluent, it be mixed in coal dust or the broken coal then, its ratio is used the combustion-supporting smoke suppressor diluent of 500kg approximately for each ton coal.
Through various coal dusts or broken coal are tested, prove that combustion-supporting smoke suppressor of the present invention has good combustion-supporting smoke effect.
Enumerate embodiment below and further explain the present invention.
Embodiment 1
(1) preparation nitrate aqueous solution
Press ammonium nitrate: the weight ratio of water=19: 90 is mixed, and is standby behind the wiring solution-forming;
(2) preparing lime milk
By unslaked lime: be mixed with uniform milk of lime after the weight ratio of water=10: 90 fully stirs;
(3) according to following prescription (weight part) methyl alcohol 14 ethanol 11 polysorbate60s 3 nitrate aqueous solutions 35 milk of limes 35 ether 1.5 of getting the raw materials ready
Earlier polysorbate60 and aqueous ammonium nitrate solution and milk of lime are mixed into homogeneous latex emulsion, even toward wherein adding methyl alcohol and ethanol and high-speed mixing then, pastly wherein add ether and high-speed mixing is even, make combustion-supporting smoke suppressor 1kg.
The combustion-supporting smoke suppressor of 1kg is mixed with 1000kg water, then this combustion-supporting smoke suppressor diluent and 2 tons of coal dusts are mixed, carry out combustion test after making two kinds of goods of honeycomb briquette and coal briquette, and with the coal product that does not add combustion-supporting smoke suppressor relatively, the result shows, after adding this combustion-supporting smoke suppressor, coal conservation is 35%, Lei Keman blackness during burning in the smog is 1.2% (national regulation is below 2%), and the Lei Keman blackness in the smog is up to 3.5% when not adding the honeycomb briquette of combustion-supporting smoke suppressor or coal briquette burning, and the Lei Keman blackness in the flue gas that coal burning boiler chimney is usually emitted is up to 8%.
Embodiment 2
According to preparing nitrate aqueous solution and milk of lime with the method for embodiment 1, different is with the ammonium nitrate among the saltpetre replacement embodiment 1.Then according to following prescription (weight part) methyl alcohol 16 ethanol 9 polysorbate60s 2.5 nitrate aqueous solutions 35 milk of limes 35 ether 2 of getting the raw materials ready
According to the method identical that various mixing of materials are even with embodiment 1, make combustion-supporting smoke suppressor 1kg.
Combustion-supporting smoke suppressor of 1kg and 1000kg water are mixed, and then mix, make two kinds of goods of honeycomb briquette and coal briquette, carry out combustion test then with 2 tons of coal dusts.The result shows that after adding this combustion-supporting smoke suppressor, coal conservation is 35%, and the Lei Keman blackness in the smog is 1.5%.
