    SLEEVE-TYPE COAL MATERIAL DECOMPOSITION APPARATUS 5 FIELD OF THE INVENTION The present invention relates to the technical field of decomposition apparatus of coal materials including pulverized coal and crushed coal, and specifically, it relates to a sleeve-type coal material decomposition apparatus. 10 BACKGROUND OF THE INVENTION In conventional technology, coal is used to produce coal gas, natural gas, or used to produce gas by coking at high temperature, medium temperature or low temperature. However, the said technology is required 15 to form pulverized coal into blocks or sift lump coal, which increases the cost of raw material, or results in the produced gas without a high heat value, a big additional value and significant economic and social benefits. The heating mode of furnace can be classified as external-heating mode, internal-heating mode and hybrid-heating mode. The heating medium in 20 external-heating furnace is not contact directly with raw materials and heat is transferred from furnace wall. The heating medium in the internal-heating furnace contacts with the raw materials directly, and the heating methods are classified as solid heat carrier mode and gas heat 1 carrier mode according to different heat media. At present, there are two kinds of conventional coal decomposition apparatuses, one of which has an up-draft kiln structure. The up-draft kiln structure is used for 5 combusting flue gas and combustible gases produced by coal, which has low gas purity and a low additional value, as well as partially discharge of gas, which results in a significant resources wasting and environmental pollution. Another kind of coal decomposition apparatus has a shaft kiln structure. In the structure, coal lumps are placed on 10 clapboard with holes, and a heater is provided above the coal lumps. Because the coal lumps on the clapboard are accumulated to a certain thickness, so they cannot be uniformly heated and decomposed, and are required to be cyclically heated and decomposed by the decomposed gas. More importantly, since the presence of large amount of 15 holes for ventilation and circulatory function provided on the clapboard, pulverized coal can leak through the holes. To avoid this, it is necessary to process the pulverized coal into coal briquette when introducing it into the shaft kiln. Thus, it will increase the cost of pulverized coal decomposition, and reduce the 20 economic benefits because the pulverized coal cannot be directly used for coal decomposition in up-draft kiln. Furthermore, in order to change the said problems, the patent 2 (authorized notice No.: CN 101985562B) named as the horizontal separation equipment with crushed coal, pulverized coal multiple burners discloses a kind of horizontal separation equipment with crushed coal, pulverized coal multiple burners comprising of a transverse rotary kiln, 5 and the said rotary kiln includes a feed inlet and a feed outlet, and multiple closely-spaced burners are set inside the said rotary kiln body in the direction of the kiln; multiple closely-spaced gas intake pipes and their parallel multiple closely-spaced air intake pipes are set correspondingly along one side of the said closely-spaced burners, the 10 said gas intake pipe connected to its corresponding burner, the said closely-spaced air intake pipe connected to its corresponding burner, and multiple closely-spaced radiating pipes are set correspondingly along another side of the said closely-spaced burners, the said multiple closely-spaced burners connected to their corresponding closely-spaced 15 radiating pipes; the said multiple closely-spaced burners are provided with theirs corresponding multiple burners; the said multiple closely-spaced burners, radiating pipes, gas intake pipes, air intake pipes and the inner wall of rotary kiln form the passage to push and separate crushed coal and pulverized coal. The said embodiment is a good solution 20 for the technical problem of adequate heating and rapid decomposition of pulverized coal, but the problem is that a small number of heating pipes fails to meeting the requirement of rapid and large heat conduction, the 3 heating pipes inside the kiln are therefore dense, and the over crowded pipes cause inconvenience for personnel when performing the overhaul and maintenance, in addition, during its operation, it requires for real-time monitoring of temperature and operation of various segments of each pipe, 5 and collection and analysis of a great number of data. When any segment of a certain pipe is in abnormal state, analysis on it shall be made or shut down for maintenance, which fails to meet the continuous and reliable manufacturing and operation and will cause significant economic loss for large-scaled high temperature integrated equipment under continuous 10 operation. Furthermore, JP2003277761 A 20031002 document discloses the patent with a title of CATALYTIC HEATING CARBONIZATION FURNACE, which intends to solve the problem: "To provide a catalytic heating carbonization furnace that reduces a running cost of the furnace 15 for carbonization treatment of organic wastes". But in this technical embodiment, the catalytic carbonization furnace is provided as a drying part used for the substance carbonization, playing a role of carbonization, and thermal decomposition part used for the carbonization of substances to be processed; firstly, the carbonization furnace uses the hot gas 20 generated from the heating catalytic combustion for the decomposition of organic matters, after which, further decomposition is conducted by using the exhaust heat, and the temperature of organic waste drops as a result of 4 the drying by the heat accumulator to improve the heat energy utilization efficiency. However, such catalytic burning equipment makes it hard for the processing of coal material, and fails to meet the demand for rapid decomposition of pulverized coal and crushed coal, and there are also 5 problems with its security and reliability. SUMMARY OF THE INVENTION To solve the above problems present in the above process, an object of the present invention is to provide a sleeve-type coal material 10 decomposition apparatus featured by more sufficient and uniform heat transmission, higher reliability and superior safety performance. A sleeve-type coal material decomposition apparatus including kiln body is characterized in that: the inside of said kiln body is set with one or multiple circular coal material decomposition-promoting layers and 15 one or multiple circular heating layers centered on the axis of kiln body; the said circular coal material decomposition-promoting layers and circular heating layers are isolated from each other; both ends of the said circular coal material decomposition-promoting layer are respectively connected to the coal inlet and coal outlet on kiln body and are also 20 connected to the decomposition gas collecting mechanism on kiln body. The said kiln body is a shaft kiln. The said kiln body is a transverse kiln. 5 The said kiln body is an inclined kiln. The said circular coal material decomposition-promoting layers and circular heating layers are in multilayer alternating arrangement. The preferred number of the said circular coal material 5 decomposition-promoting layers and circular heating layers is respectively two or more, such as 2, 3, 4, 5 or more. The said circular heating layers are electrical heating layers the inside of which is provided with the electrothermal component connected to power source. 10 The said circular heating layers are high-temperature gas heating layers which are respectively connected to high-temperature gas inlet pipe and heating gas outlet pipe. The said circular coal material decomposition-promoting layers are connected to coal inlet by material distributing cabinet and to coal outlet 15 by material collecting cabinet. The inside of said circular coal material decomposition-promoting layers is installed with feed mechanism. The said multiple circular coal material decomposition-promoting layers are connected with each other by pipeline. 20 Thanks to the arrangement of coal material decomposition-promoting layers and circular heating layers centered on the axis of kiln body inside the kiln body, the said coal material 6 decomposition-promoting layers and circular heating layers are isolated from each other, which is helpful for the acquisition of pure coal decomposition gas and provides favorable technical support for further decontamination, purification and liquidation; in addition, the alternating 5 arrangement of coal material decomposition-promoting layers and circular heating layers allows the coal material decomposition-promoting layers and circular heating layers to be in contact with and close to each other, which enables the heat released from circular heating layers to be fully absorbed by adjacent set coal material decomposition-promoting 10 layers via conduction and radiation forms; the full absorption of pulverized coal improves the efficiency of heat absorption, brings better effect of complete decomposition and generates fuel gas, tar gas and coal with higher heat value in coal material decomposition-promoting layers. What's more, it changes the status quo of dense arrays of heating pipes 15 inside the kiln body so as to bring convenience to workers for maintenance, and further enhance the reliability and stability; besides, in the working process, real-time monitoring of the temperature and running condition of each section of each pipe will be not necessary, thereby there will be less data to be grasped and analyzed and the operating stability 20 and accuracy will be higher; for the large high-temperature integrated equipments in continuous operation, stability and reliability mean great economic benefits. The said multiple coal material 7 decomposition-promoting layers are connected with each other by breather pipe, which makes it easier to collect the coal decomposition gas generated in each circular layer together via the center or the circular layer close to center; the structure for collecting decomposition gas is 5 quite simple and reliable. Such circles-within-circles structure in annual ring form disclosed by the present invention makes the decomposition and separation of the pulverized and crushed coal more fast and efficient so as to save and fully utilize energy and greatly increase the utilization rate and level of coal resources, thus it will produce a significant 10 economic and social benefits for the entire society.
