Description
Technical field
The utility model belongs to the comprehensive utilization of coal material, energy-conserving and emission-cutting technology field, is specifically related to a kind of coal material decomposition horizontal revolving equipment.
Background technology
In known technology, the coal system of utilization coal gas is arranged, have and utilize the coal preparing natural gas, utilize coal to carry out high temperature, middle temperature, semi-coking, system gas in addition, but above-mentioned processing method is not coal dust to be rolled into a ball caked, will screen the piece material exactly, raw materials cost increases, or institute's aerogenesis calorific value is not high, and added value is little, and economic benefit and social benefit are not remarkable.It is hybrid that the type of heating of stove can be divided into external-heat, internal heat type and the outer heat of interior heat.The heating medium of external-heat stove does not directly contact with raw material, and heat is imported into by the furnace wall; The heating medium of internal heat type stove directly contacts with raw material, because of the difference of heating medium has two kinds of the gentle body heat support methods of solid heat carrier method.
Internal heat type gaseous heat-carrier method is the industrial typical method that has adopted.This method adopts gaseous heat-carrier internal heat type vertical continuous stove, promptly comprises dryer section from top to down, decomposes section and cooling section three parts.(about 25～60mm) from top to bottom move, and directly contact with the burning gas adverse current and are heated for coal low-temperature decomposition brown coal or the type piece that is pressed into by brown coal.About 15% o'clock of the water content of furnace roof raw material removes below the moisture to 1.0% in dryer section, and upstream about 250 ℃ of hot gass are chilled to 80～100 ℃.Dry back raw material is heated to about 500 ℃ in the decomposition section by 600～700 ℃ of oxygen-free burning gas, and thermolysis takes place; Hot gas is chilled to about 250 ℃, and the semicoke of generation enters cooling section and cooled off by cold air.Semicoke is discharged back further water and air cooling.From decomposing section volatile matter of overflowing, obtain tar and pyrolysis water through steps such as condensation, coolings.This type of type of furnace was all once had in Germany, the U.S., the Soviet Union, Czechoslovakia, New Zealand and Japan.
The internal heat type solid heat carrier method is the typical method of solid thermal carriers internal heat type.Raw material is brown coal, noncaking coal, weak caking coal and resinous shale.Be the pilot plant of 10t/h coal in this Teng Jianyou one cover processing power of Germany Dorr the 1950's, and the thermal barrier of use is solid particulate (little porcelain ball, sand or a semicoke).Because the process product gas does not contain waste gas, so the equipment size of after-treatment system is less, caloric power of gas is higher, can reach 20.5～40.6MJ/m
3Therefore this method has very big processing power because the temperature difference is big, and particle is little, and heat transfer is exceedingly fast.The gained liquid product is more, during the processing high volatile coal, productive rate can reach 30%.L-R method technical process coal low-temperature decomposition is at first with the fritter feed coal of preliminary preheating, mixes in mixing tank with the hot semicoke from separator, and the thermolysis effect takes place.Fall into then in the snubber, stop certain hour, finish thermolysis.The semicoke that comes out from snubber enters the riser tube bottom, is submitted by warm air, and burning-off carbon residue wherein in riser tube elevates the temperature simultaneously, enters then and carries out gas solid separation in the separator.Semicoke returns mixing tank again, so circulation.Volatile matter from mixing tank is overflowed through dedusting, condensation and cooling, recovery oils, obtains the higher coal gas of calorific value.
Current, coal resolving device commonly used mainly is to have two kinds, and having a kind of is the shaft furnace structure, and the inflammable gas that this structure combustion product gases and coal produce makes that the purity of combustible gas is low, and added value is low, also has part to discharge, and causes a large amount of wastes of resource and the pollution of environment.Another kind of shaft kiln is that coal cinder is placed on the dividing plate with holes, coal cinder top having heaters, because of the coal cinder on the dividing plate has certain ulking thickness, can not be by even heating, decomposition, need heat, decompose with the gas circulation that is decomposed, what is more important, because a large amount of existence of coal dividing plate cocycle ventilating pit, coal dust can leak down from ventilating pit, so coal dust need be processed coal-forming group earlier when coal dust need enter shaft kiln, separate so coal dust can not be directly used in the kiln body, this has just correspondingly increased the cost that coal dust decomposes, and has reduced economic benefit.
