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 vertical resolving device of coal material.
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.

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 coal cinder has certain thickness, can not be by even heating, decomposition, need heat, decompose with the gas circulation that is decomposed, the speed that lump coal decomposes is lower than coal dust, what is more important, because a large amount of existence of coal dividing plate cocycle ventilating pit, coal dust can leak down come from ventilating pit, so coal dust need be processed coal-forming group earlier when coal dust need enter shaft kiln, separates so coal dust can not be directly used in shaft kiln, this has just correspondingly increased cost, has reduced economic benefit.
