The invention also aims to provide application of the mixed energy-saving fuel, which is particularly used for combustion in industrial boilers, power station boilers and industrial kilns.
Compared with the prior art, the method has the following beneficial effects:
(1) The invention uses coal, water and oil as main raw materials to prepare a mixed fuel which can be pumped, atomized, stored and transported like oil and can be directly used for burning in various boilers and kilns. And the coal is mixed in water and oil, so that the coal is combusted more fully, the 'micro-explosion' effect and the water gas principle generated by the participation of water further reduce pollution emission, and the coal is safer and more reliable in storage and transportation. And the used water can be industrial wastewater, such as chemical industrial wastewater, paper-making industrial wastewater, food industrial wastewater and the like, so that the discharge of the industrial wastewater is greatly reduced, the pollution problem to soil and water bodies is further reduced, and the aims of saving energy and protecting environment are fulfilled.
(2) The invention uses the mixture of fatty alcohol polyvinyl chloride ether, polyvinyl chloride castor oil, triethanolamine and antioxidant as polymerization agent, so that the mixture has emulsification polymerization effect between oil and water, oil and water are better mixed, coal powder is better suspended in emulsified oil, the three can be better mixed, coal powder particles can not break through an oil film more quickly, and the storage is longer. The fatty alcohol-polyoxyethylene ether is used as a nonionic surfactant, is dissolved in water and various organic solvents, has the functions of emulsification, dispersion and diffusion, can be used as a water-in-oil emulsifier, has good biodegradability and is environment-friendly; the polyoxyethylene ether castor oil is a modified castor oil product, can be dissolved in most organic solvents, is dispersed in water, and can be used as an efficient solubilizer to ensure that the solution is more stable; triethanolamine is an organic compound, is soluble in water and alkalescent, relieves the pH value of a solution, and can effectively protect the surface of a metal container. The HLB value of the mixed fuel can reach or approach to a required numerical value by using the compatibility of the fatty alcohol-polyoxyethylene ether and the polyoxyethylene ether castor oil, so that the prepared emulsion is more stable.
(3) This application has realized the intensive mixing of buggy in aqueous, has increased the contact of the organic hydrocarbon in water and the coal, more abundant in the burning with oil, has improved combustion efficiency, reaches the pollution abatement, reduces the dual effect of discharging. The addition of the polymerization agent has an emulsification effect, and the problems that the coal water slurry is easy to layer and the mechanical wear is reduced are solved.

And comparing the influence of different mesh numbers of coal dust on the stability of the obtained mixed energy-saving fuel.
Comparative example 1:
the comparative example differs from example 1 in that: the coal dust is above 325 mesh (i.e. sieved through 325 mesh), as shown in fig. 8. The remaining raw material types and preparation parameters were the same as in example 1.
The specific process for preparing the mixed energy-saving fuel of the comparative example is carried out according to the following steps:
step 1, weighing required raw materials in proportion for later use;
the concrete raw material ratio is as follows: 30 parts of water, 1.75 parts of polymerization agent, 10 parts of coal powder, 60 parts of diesel oil and 0.25 part of additive.
Wherein the polymerization agent consists of 40 percent of fatty alcohol polyvinyl chloride ether, 55 percent of polyvinyl chloride castor oil, 3 percent of triethanolamine and 2 percent of antioxidant. Wherein, the antioxidant is BHA and is oil-soluble antioxidant, and the antioxidant and the decomposition product are nontoxic and harmless and have good stability, and can realize coexistence of oil and water. The pulverized coal has a particle size of 325 meshes or more and a bulk density of 0.8-0.9t/m 3 . The diesel oil is 0# diesel oil. The additive is EDTA-2Na which is a good compounding agent, can improve the oxidation resistance of the grease, and can effectively prevent discoloration, deterioration, turbidity and the like caused by metal ions.
And 2, adding water into the reaction kettle, adding a polymerization agent, stirring for 5min under the condition of 600r/min, adding coal powder under the stirring condition after the coal powder is fully dissolved, greatly reducing the floating of the coal powder in the air, further improving the safety, adding diesel after the coal powder is completely added, regulating the speed to 1500r/min, uniformly mixing, and adding an additive to obtain the mixed energy-saving fuel.
Comparing example 1 with the energy-saving fuel mixture obtained in the present comparative example, it is known that the energy-saving fuel mixture obtained in the present comparative example has general stability and poor fluidity, and the nozzle is easily clogged during use. And the mixed energy-saving fuel obtained by the comparative example can stably burn but has black smoke in a combustion test.
Comparative example 2:
the comparative example differs from example 1 in that: the coal powder is more than 100 meshes (namely 100 meshes of sieve is sieved). The remaining raw material types and preparation parameters were the same as in example 1.
The specific process for preparing the mixed energy-saving fuel of the comparative example is carried out according to the following steps:
step 1, weighing required raw materials in proportion for later use;
the concrete raw material ratio is as follows: 30 parts of water, 1.75 parts of polymerization agent, 10 parts of coal powder, 60 parts of diesel oil and 0.25 part of additive.
Wherein the polymerization agent consists of 40 percent of fatty alcohol polyvinyl chloride ether, 55 percent of polyvinyl chloride castor oil, 3 percent of triethanolamine and 2 percent of antioxidant. Wherein, the antioxidant is BHA and is oil-soluble antioxidant, and the antioxidant and the decomposition product are nontoxic and harmless and have good stability, and can realize coexistence of oil and water. The grain diameter of the coal powder is more than 100 meshes, and the bulk density is 0.8-0.9t/m 3 . The diesel oil is 0# diesel oil. The additive is EDTA-2Na which is a good compounding agent and can improve the oxidation resistance of the grease and effectively prevent discoloration, deterioration, turbidity and the like caused by metal ions.
And 2, adding water into the reaction kettle, adding a polymerization agent, stirring for 5min under the condition of 600r/min, adding coal powder under the stirring condition after the coal powder is fully dissolved, greatly reducing the floating of the coal powder in the air, further improving the safety, adding diesel after the coal powder is completely added, regulating the speed to 1500r/min, uniformly mixing, and adding an additive to obtain the mixed energy-saving fuel.
Comparing example 1 with the mixed energy-saving fuel obtained by the comparative example, it can be seen that the mixed energy-saving fuel obtained by the comparative example has poor stability, mainly because the coal powder has large particle size, and is easy to cause precipitation and stratification.
Comprehensive comparison shows that the mixed energy-saving fuel prepared by using 200-mesh coal powder has the best viscosity and the best stability.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
