Description
Technical field
The invention belongs to coal material comprehensive utilization, energy-conserving and emission-cutting technology field, be specifically related to a kind of coal material horizontal intubation vertical decomposition equipment.
Background technology
In known technology, have and utilize coal coal gas processed, have and utilize the coal preparing natural gas, utilize in addition coal to carry out high temperature, middle temperature, semi-coking, gas processed, but above-mentioned processing method is not rolled into a ball into piece with coal dust, 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 the outer heat of external-heat, internal heat type and 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 the difference of heating medium has two kinds of solid heat carrier method and air heat support methods.
Internal-heating gas thermal barrier method is the industrial typical method that has adopted.This method adopts gaseous heat-carrier internal heat type vertical continuous stove, namely comprises from top to down dryer section, decomposes section and cooling section three parts.Coal low-temperature decomposition brown coal or the type piece that is pressed into by brown coal (approximately 25～60mm) from top to bottom move, directly contact with the burning gas adverse current and be heated.The water content of furnace roof raw material approximately 15% the time, removes below moisture to 1.0% in dryer section, and upstream approximately 250 ℃ of hot gass are chilled to 80～100 ℃.After dry, raw material is heated to approximately 500 ℃ in the decomposition section by 600～700 ℃ of oxygen-free burning gas, and thermolysis occurs; Hot gas is chilled to approximately 250 ℃, and it is cooling by cold air that the semicoke of generation enters cooling section.Further water and air cooling after semicoke is discharged.From decomposing a volatile matter that section overflows through a condensation, the step such as cooling, obtain tar and pyrolysis water.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 semicoke).Because process product gas does not contain waste gas, so the equipment size of after-treatment system is less, and caloric power of gas is higher, can reach 20.5～40.6MJ/m
3This method is because the temperature difference is large, and particle is little, and heat transfer is exceedingly fast, and therefore has very large processing power.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 occurs.Then fall in snubber, stop certain hour, complete thermolysis.Enter riser tube bottom from snubber semicoke out, submitted by warm air, burning-off carbon residue wherein in riser tube, elevate the temperature simultaneously, then enters and carry out gas solid separation in separator.Semicoke returns to 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 is mainly 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 the purity of combustible gas 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 dividing plate with holes, coal cinder top having heaters, because the coal cinder on dividing plate has certain ulking thickness, can not be by homogeneous heating, decomposition, need to heat with the gas circulation that is decomposed, decompose, 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 first need when coal dust need to enter shaft kiln coal dust is processed coal-forming group, separate so coal dust can not be directly used in shaft furnace, this has just correspondingly increased the cost that coal dust decomposes, and has reduced economic benefit.
