Description

Coal material decomposition horizontal revolving equipment
Technical field
The invention belongs to the comprehensive utilization of coal material, energy-conserving and emission-cutting technology field, be specifically related to a kind of coal material decomposition horizontal revolving 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 by coal dust, will screen the piece material exactly, raw materials cost increases, or institute's aerogenesis calorific value is not high, 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 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 adopted.This method adopts gaseous heat-carrier internal heat type vertical continuous stove, comprises from top to down dryer section, decomposes section and cooling section three parts.Coal low-temperature decomposition brown coal or the type piece (approximately 25~60mm) be pressed into by brown coal from top to bottom move, and with the burning gas adverse current, directly contact and are 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.Semicoke is further water and air cooling after discharging.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.The 1950's, the pilot plant that is the 10t/h coal in a set of processing power of this Teng Jianyou of Germany Dorr, 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 3.This 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 by the fritter feed coal of preliminary preheating, with the hot semicoke from separator, in mixing tank, mixes, and the thermolysis effect occurs.Then fall in snubber, stop certain hour, complete thermolysis.From snubber, semicoke out enters the riser tube bottom, by warm air, is submitted, and burning-off carbon residue wherein in riser tube, elevate the temperature simultaneously, then enters in separator and carry out gas solid separation.Semicoke returns to mixing tank again, so circulation.The volatile matter of overflowing from mixing tank, through dedusting, condensation and cooling, recovery oils, obtain the coal gas that calorific value is higher.
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, make 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 by the gas circulation be 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 to coal-forming group, so coal dust can not be directly used in the kiln body, separate, this has just correspondingly increased the cost that coal dust decomposes, and has reduced economic benefit.
Summary of the invention
The present invention is for solving the problem existed in above-mentioned technique and method, proposed a kind of can be directly by the coal dust separating substances, improve its comprehensive utilization value, energy-saving and emission-reduction, thereby the coal material decomposition horizontal revolving equipment improved the economic and social benefits.
A kind of coal material decomposition horizontal revolving equipment, comprise a horizontal sealing rotary kiln body, described rotary kiln body comprises an opening for feed, a discharge port, along kiln body direction, a combustion unit is set in described rotary kiln body, described combustion unit is by gas inlet pipe, air intake duct, burner, lighter for ignition, flame gas radiating pipe, heat absorption or radiator element form in a large number.Described gas inlet pipe, air intake duct be arranged in parallel along the axis direction of rotary kiln body, described burner one side is communicated with described gas inlet pipe, air intake duct, the opposite side of described burner is communicated with the flue gas radiating pipe, described lighter for ignition is arranged in burner, and a large amount of heat absorptions or heat radiation flap all are set on described gas inlet pipe, air intake duct and flame gas radiating pipe.Form the coal material between described combustion unit and rotary kiln body inwall and advance split tunnel, described coal material advances split tunnel to be communicated with described opening for feed and discharge port, described rotary kiln body upper feeding mouth place end arranges the isolated combustion gas of coal, tar gas collection tube, the isolated combustion gas of described coal, tar gas collection tube advance split tunnel to be communicated with the coal material, and the other end is connected with combustion gas dedusting liquid body.The described flame gas manifold trunk the other end stretches out outside rotary kiln and is communicated with coal preheating, drying installation.
The coal dust propulsive mechanism of kicking up is set on described rotary kiln body inwall.
