Description
Technical Field
The utility model relates to a raw coal upgrading equipment technical field, concretely relates to spiral reactor and apparatus for producing that is used for high-efficient dehydration of raw coal and calorific value to promote.
Background
Coal is the basic energy of China, and from low-metamorphic lignite to high-metamorphic anthracite, the coal types in China are complete, wherein the bituminous coal accounts for 75% at most, and the proportion of lignite and anthracite is about 12% and 13% respectively.
Low-rank coals, for example: lignite is brown black low-grade coal which has low deterioration degree and is between peat and bituminous coal, is a coal type with high volatile components and internal moisture, and has the characteristics of easy weathering when encountering air and easy argillization when encountering water. Therefore, the quality of the lignite is improved, the water content and the oxygen content are reduced, the heat value of the lignite is improved, the problems of serious environmental pollution and low heat utilization rate when low-grade coal is directly combusted are solved, the quality and the comprehensive utilization value of the lignite are improved, the application field of the lignite is expanded, and the lignite can be better applied to chemical production, electric power industry and metallurgical industry in China.
The low-calorific-value coal upgrading process mainly reduces impurities such as moisture, ash and the like in the coal and improves the calorific value of the coal. The dehydration and upgrading of the low-calorific-value coal can reduce the long-distance transportation cost of the coal on one hand, and on the other hand, the lignite after dehydration and upgrading has higher flame temperature and thermal efficiency from the combustion perspective.
At present, the dehydration and upgrading of low-calorific-value coal are mostly carried out by adopting a water vapor indirect drying method or a flue gas drying method, and the treated lignite is very easy to generate spontaneous combustion in the storage and transportation processes due to high activity. The flue gas drying process also has potential safety hazards of explosion. Some domestic enterprises and scientific research departments also make many researches and researches on the technology of drying and upgrading low-calorific-value coal, and various methods for reducing the moisture of the coal are available, such as: the coal motion modes include fluidized bed, moving bed and air bed, the heating modes include internal heating mode and external heating mode, and the heating modes include steam method and flue gas method.
Another example is: CN 208785869U discloses a vertical coal slime hydroextractor, including support, feed hopper and screen cloth, feed hopper sets up in the support top, and the feed hopper below is rotary device, and the inside feed inlet that is of rotary device, the rotary device both sides are provided with runing rest, are provided with the slide rail between runing rest and the support, are provided with the roller of rolling between runing rest and the rotary device, and the screen cloth setting is in the rotary device below, and the screen cloth bottom is provided with drainage pipe. The coal slime hydroextractor in this scheme rolls the dehydration through physics, though the potential safety hazard that brings in the production process has been reduced to a certain extent, also can reduce certain energy consumption and use, but its dehydration efficiency is not high, still can not improve the calorific value of coal slime betterly simultaneously.
Therefore, the existing low-calorific-value coal dehydration process at home and abroad basically has the defects of high energy consumption, high cost, poor effect, poor safety, unstable operation and the like.
