Description
Technical field
This utility model belongs to fine coal processing technique field, is 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 production maximum in the world and country of consumption,
Within one considerably long period, the status that coal resources dominate the energy as China is unshakable.According to statistics, China is
Verifying coal reserves is 114,500,000,000 tons, and wherein middle low-order coal (brown coal, lower-grade metamorphic bituminous) accounts for again whole nation reserves
About 55.15%.Owing to low-order coal has moisture height, easy-weathering spontaneous combustion, is difficult to sorting, should not transport for long-distance and storage etc.
Feature so that its comprehensive utilization is very limited.Wherein directly combustion power generation is one of its modal Land use systems.According to not
Adding up completely, there are the brown coal of more than 90% in China for station boiler and various Industrial Boiler.Low-order coal is as thermal coal fuel
Directly burning, not only wastes the hydrocarbon rich resource contained in coal, and efficiency is low.Fired with semicoke by low-temperature pyrolysis of coal
Burn, gasification decouples, it is achieved low-order coal classification high-efficiency cleaning trans-utilization, is the Main way of present large-scale Coal Chemical Industry.
It is widely used along with modernization coal mining is polytechnic so that the ratio of lump coal declines (by 40% current decline 10
～20%), fine coal productivity raises (being risen to 80～90% by current 60%).There is easy airborne dust, inflammable, explosive in fine coal, combines
Conjunction utilizes the problems such as difficulty is big, pyrolysis of coal technology to be considered as 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 is: raw material is through being crushed to
Below 12.7mm, enters coal and is dried and preheater 2, is being dried and in preheater, coal and heat smoke contact mass transfer heat exchange.Drying and preheating
After fine coal, carried to cyclone separator 3 by heat smoke.In cyclone separator 3, coal separates with useless flue gas, after drying and preheating
Coal enter pyrolysis reactor 6, and from the red-hot porcelain mixed pyrolysis in Ceramic Balls preheater 4.Pyrolysis of coal product and porcelain ball exist
Separating in sifter 7, pyrolysis char is discharged after cooling, is pyrolyzed oil gas fractional distillation in fractionating column, pyrolysis coal gas and air at pottery
In porcelain ball pyrolysis apparatus, the cold porcelain ball heat supply from riser 8 is given in burning, it is achieved recycling of cold and hot porcelain ball.
Toscoal hot solid carrier devolatilization technique uses partial thermal decomposition gas-fired, is heated by cold porcelain ball.Porcelain after heating
Ball and dried coal mixed pyrolysis in pyrolysis reactor, produce pyrolysis oil gas and semicoke.Semicoke and the screened separation of porcelain ball
After, semicoke cools down, and the boosted pipe of porcelain ball 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 in Ceramic Balls, and during airlift conveying Ceramic Balls, to pipeline and
Equipment inner wall has a certain degree of abrasion.
Additionally, pyrolysis reactor uses rotary kiln, the oil gas time of staying that pyrolysis produces is long, and oil gas secondary response is violent,
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's mansion SH internal thermal upright carbonization furnace technological process
For: after raw coal (20～150mm) after crushing and screening, it is delivered to the coal tower of furnace roof, enters uprightly through sealing-tape machine, coal valve and auxiliary coal bin
In stove.Lump coal in upright furnace moves from top to bottom, with high-temperature gas counter current contacting.Upright furnace top is lump coal preheating section, in advance
Lump coal is preheated to 360～400 DEG C by hot arc；Lump coal after preheating enters the retort section in the middle part of upright furnace, and retort section lump coal is added
Heat, to 680～720 DEG C, produces semicoke and pyrolysis gas, and semicoke is discharged by cooling after the cooling section of carbonization chamber bottom, pyrolysis gas warp
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 slightly
Coal gas and tar, as the heating fuel of upright furnace after raw 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, and the pyrolysis petroleum resources produced after pyrolysis is by gas
Heat carrier dilutes, 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, and oil gas secondary response is violent, tar product
Matter is the highest.
Equipment is huge, is difficult to operation.
