Description
Technical field
The invention belongs to fine coal processing technique field, be specifically related to a kind of fine coal rapid pyrolysis apparatus.
Background technology
The energy resource structure feature of China is rich coal, gas oil-poor, few.As coal maximum in the world
Production and consumption state, within one considerably long period, coal resources dominate the energy as China
Status is unshakable.According to statistics, it is 114,500,000,000 tons that China has verified coal reserves, wherein
Middle low-order coal (brown coal, lower-grade metamorphic bituminous) accounts for again about the 55.15% of whole nation reserves.
Due to low-order coal have moisture height, easy-weathering spontaneous combustion, be difficult to sorting, should not transport for long-distance and
The features such as storage so that its comprehensive utilization is very limited.Wherein directly combustion power generation be its
One of common Land use systems.According to incompletely statistics, there are the brown coal of more than 90% in China for power station
Boiler and various Industrial Boiler.Low-order coal is directly burnt as thermal coal fuel, not only wastes coal
The hydrocarbon rich resource contained in charcoal, and efficiency is low.By low-temperature pyrolysis of coal and coal-char combustion,
Gasification decoupling, it is achieved low-order coal classification high-efficiency cleaning trans-utilization, is the master of present large-scale Coal Chemical Industry
Want direction.
It is widely used along with modernization coal mining is polytechnic so that the ratio of lump coal declines (by present
40% decline 10～20%), fine coal productivity raise (being risen to 80～90% by current 60%).
There is easy airborne dust, inflammable, explosive, the problems such as comprehensive utilization difficulty is big, pyrolysis of coal technology quilt in fine coal
It is considered the maximally efficient approach of coal high-efficiency clean utilization.
Prior art one
Of the prior art Toscoal hot solid carrier devolatilization technique is briefly described below.
Fig. 4 is the process chart of prior art one.As shown in Figure 4, the technological process of this technique
For: raw material, through being crushed to below 12.7mm, enters coal and is dried and preheater 2, is being dried and preheating
In device, coal and heat smoke contact mass transfer heat exchange.Fine coal after drying and preheating, by heat smoke carry to
Cyclone separator 3.In cyclone separator 3, coal separates with useless flue gas, the coal after drying and preheating
Enter pyrolysis reactor 6, and from the red-hot porcelain mixed pyrolysis in Ceramic Balls preheater 4.Coal heat
Hydrolysis products and porcelain ball separate in sifter 7, and pyrolysis char is discharged after cooling, and pyrolysis oil gas exists
Being fractionated in fractionating column, pyrolysis coal gas and air burn to from riser 8 in Ceramic Balls pyrolysis apparatus
Cold porcelain ball heat supply, it is achieved recycling of cold and hot porcelain ball.
Toscoal hot solid carrier devolatilization technique uses partial thermal decomposition gas-fired, is added by cold porcelain ball
Heat.Porcelain ball after heating and dried coal mixed pyrolysis in pyrolysis reactor, produce pyrolysis oil
Gas and semicoke.After semicoke and the screening of porcelain ball warp separate, semicoke cools down, and porcelain ball warp riser is promoted to
Ceramic Balls preheater waste heat, completes once to circulate.
Prior art one has the drawback that
In cyclic process, there is mechanical wear, and the mistake of airlift conveying Ceramic Balls in Ceramic Balls
Cheng Zhong, has a certain degree of abrasion to pipeline and equipment inner wall.
Additionally, pyrolysis reactor uses rotary kiln, the oil gas time of staying that pyrolysis produces is long, oil gas
Secondary response is violent, and tar quality declines.
And, after pyrolysis, semicoke and Ceramic Balls are completely separated difficulty.
Prior art two
Fig. 5 is the process chart of prior art three.As it is shown in figure 5, god mansion SH internal heat type is straight
Vertical retort technological process is: after raw coal (20～150mm) after crushing and screening, be delivered to furnace roof
Coal tower, through sealing-tape machine, coal valve and auxiliary coal bin enter in upright furnace.Lump coal in upright furnace is from upper
And lower movement, with high-temperature gas counter current contacting.Upright furnace top is lump coal preheating section, and preheating section will
Lump coal is preheated to 360～400 DEG C；Lump coal after preheating enters the retort section in the middle part of upright furnace, destructive distillation
Section lump coal is heated to 680～720 DEG C, produces semicoke and pyrolysis gas, and semicoke passes through carbonization chamber bottom
Cooling section after cooling discharge, pyrolysis gas through tedge, bridge tube enter pneumatic trough.In pneumatic trough,
High-temperature hot is vented one's spleen by about cyclic ammonia water spraying cooling to 80 DEG C, obtains raw gas and tar, rough coal
As the heating fuel of upright furnace after gas is purified.
Prior art two has the drawback that
SH type internal thermal upright carbonization furnace PROCESS FOR TREATMENT lump coal, is not suitable for pulverized coal pyrolysis.
SH type internal thermal upright carbonization furnace technique uses gas heat carrier, the pyrolysis produced after pyrolysis
Petroleum resources is diluted by gas heat carrier, and calorific value is low.
Pyrolysis petroleum resources condensation number is big.
Lump coal volume is big, and heat transfer coefficient is low, and heat transfer efficiency is the highest, and pyrolysis time is long, oil gas secondary
Acutely, tar quality is the highest in reaction.
Equipment is huge, is difficult to operation.
