Abstract
The invention relates to a high-intensity compound coal and a preparation method thereof, which pertains to the field of utilization of recycling energy and coal deep processing. The invention is characterized in that the invention comprises the materials by weight ratio: waste plastic of 2-40 percent, binder of 5-20 percent, limestone or slaked lime of 0.05-5 percent and the rest being coal. The wasted plastic is stirred with other materials evenly after being grinded. When below the temperature of 50 DEG C, the mixture is made into the high-intensity compound coal by cold-pressing formation. The invention improves the utilization ratio of energy, and efficiently utilizes domestic and producing refuses such as waste and old plastic and sulfite waste liquor, thus reducing environmental pollution. The waste and old plastic belongs to a high molecular compound, which is characterized by high combustion value and free burning propriety. In the meantime, the waste and old plastic can dissolve and permeate with coal particles during the course of the combustion, and become the skeleton of the briquette, so as to improve the calorific intensity without effect of a heating value and the sulfur capturing efficiency of the limestone and the burned lime in the process of briquette. Meanwhile, the process can reduce the emission of oxides and improve the combustion efficiency greatly.
Description
One, technical field
The present invention relates to a kind of high-strength composite molded coal and preparation method, belong to utilization of regenerative energy and coal deep processing field.
Two, background technology
The method that several production moulded coals are also arranged at present, as Chinese patent (publication number: CN1318630A) disclose the manufacture method of a kind of low public hazards, golf calorific value moulded coal, it is by low rank bituminous coal, thermoplastic waste plastic, pitch and residual oil, Wingdale or white lime, under 200-450 ℃ temperature, mix,, the fusing after make.Its shortcoming is: plastics are as tamanori, at high temperature with the coal moulding.And for example (publication number: CN1648220A), disclose a kind of environment protection clean composite briquette and preparation method thereof, it is that plastics are as tamanori, at high temperature with the coal moulding to Chinese patent too.Facts have proved that plastics at high temperature can not stick together with coal, therefore can not moulding, and cause the cost of moulded coal to increase substantially.
Three, summary of the invention
The object of the present invention is to provide a kind of can be good to stick together with coal, cost is low, and is combustion-supporting fast, a kind of high-strength composite molded coal and preparation method that calorific value is high.
Technical solution: the present invention is made of by weight following material, waste or used plastics 2-40%, and tamanori 5-20%, Wingdale or white lime 0.05-5%, all the other are coal.
Tamanori is spent pulping liquor, humate, the acid of rotten branch, lignocellulose, water glass.
Waste or used plastics is PE, PP, PS, and ABS one or more in forming.
The preparation method of high-strength composite molded coal, its technology is as follows: waste or used plastics pulverized, even with coal dust, tamanori, Wingdale or slaked lime under agitation then, mix, be lower than in temperature under 50 ℃ the condition, high-strength composite molded coal is made in coldmoulding.
The present invention has improved energy utilization rate, has effectively utilized lives such as waste or used plastics and spent pulping liquor, has produced rubbish, has reduced the pollution to environment.Waste or used plastics belongs to macromolecular compound, has the high combustion value, incendive characteristics, and in combustion processes, can dissolve each other with the coal grain and permeate, can become the skeleton of moulded coal, improved the hot strength of moulded coal; The type cold strength of making can reach more than the 800/N ball, and is not influence calorific value, and Wingdale or white lime solid sulphur efficiency in the moulded coal combustion processes can be stated more than 90%.Simultaneously, can reduce oxide compound NO
xDischarging, improve efficiency of combustion greatly.
