Abstract
Coal fast pyrogenation of the present invention and producing acetylene by plasma pyrolysis group technology, belong to Coal Chemical Industry and coal field of scientific study, it is characterised in that provide a kind of coal fast pyrogenation and producing acetylene by plasma pyrolysis group technology.Coal is circulated into fast pyrogenation using hot semicoke, high temperature pyrolysis gas produces acetylene to low energy consumption directly as the raw material of producing acetylene by plasma pyrolysis, and high-temperature semi-coke is used as gasified raw material, desulfurizing agent or adsorbent.
Description
Technical field
A kind of coal fast pyrogenation of the present invention and producing acetylene by plasma pyrolysis group technology, belong to Coal Chemical Industry and
Coal scientific domain.
Background technology
Bian plasma reactors, acetylene is directly produced by coal dust, can fundamentally be solved " three wastes "
Pollution problem.More importantly the power consumption of per kilogram acetylene is suitable with carbide, and without coke and stone
Lime stone is used as raw material.Because the coal reserves of China quite enriches, petroleum resources are short, develop Coal Chemical Industry pair
There is special significance in the development of China's chemical industry.But coal direct plasma be pyrolyzed acetylene processed due to
The inherent characteristic of coal increases the difficulty for solving the problems, such as yield, energy consumption and long-term operation.Coal processing first
Coal dust into suitable particle diameter distribution needs certain energy consumption, and easily pollutes environment；Pulverized coal preheating is difficult,
Being conveyed with fluid bed needs special equipment and energy consumption；Secondly coal dust enters in plasma high-temperature jet,
First being preheating to high temperature and release volatile materials, acetylene etc. is generated followed by there is radical reaction.This
A portion coal dust can not enter plasma jet high-temperature region, and reactor is thrown to by swirling eddy centrifugation
Wall, tacky gradually forming of being heated accumulates Jiao；A part of coal dust partially or completely not yet reacts, and leaves high temperature
Area forms the residual coal of high temperature and leaves reaction system through chilling.It is larger that rear portion coal dust accounts for total raw material share,
About 70%, from macroscopically, the thermal cycle first heated and cool down again is simply experienced, consume in vain a large amount of
Energy, and itself is not changed, and contribution is not produced to acetylene processed.The direct plasma of other coal
Body heat solution acetylene also has requirement higher to coal, plasma generator be also into gas through electric arc by
Low temperature is added to high temperature and forms plasma jet.
Coal fast pyrogenation be coal effectively using and one of value-added Main Means, it is active greatly to produce high-temperature semi-coke,
It is the quality raw materials of gasification, also can be used as desulfurizing agent and adsorbent；Institute's heat production vent one's spleen calorific value it is high, containing big
The cyclic hydrocarbon and methane of amount, can be used as combustion gas and industrial chemicals.But the pyrolysis gas of existing coal fast pyrolysis process
Detar is usually first cooled down, used as combustion gas, tar carries out separating production chemical products dry gas in heating.
There is Energy Efficient from the point of view of coal direct plasma is pyrolyzed acetylene processed and fast pyrolysis process individually
The defect of utilization rate difference, but two process energies utilizations have complementarity.
The content of the invention
Mesh ground of the invention is that a kind of coal fast pyrogenation and producing acetylene by plasma pyrolysis group technology are provided to overcome the shortcomings of prior art to exist.
It is to use coal that the present invention provides a kind of coal fast pyrogenation and producing acetylene by plasma pyrolysis group technology
Hot semicoke circulates fast pyrogenation, high temperature pyrolysis gas directly as producing acetylene by plasma pyrolysis raw material, low energy
Consumption ground production acetylene, high-temperature semi-coke is used as gasified raw material, desulfurizing agent or adsorbent.It is provided by the present invention
A kind of coal fast pyrogenation and producing acetylene by plasma pyrolysis group technology, make use of what coal fast pyrogenation was produced
High temperature pyrolysis gas fully, reasonably make use of pyrolysis gas heat as the raw material of producing acetylene by plasma pyrolysis
Amount and quality, be also plasma produce high-quality energy be able to rationally utilize, the production second of low energy consumption
Alkynes, while high-temperature semi-coke improves the added value of coal, gas as gasified raw material, desulfurizing agent or adsorbent
Mutually charging is conducive to mixing, reduces or inhibit green coke on reactor wall, it is ensured that plasma pyrolysis connect
Continuous and long-term operation, disposal ability, conversion ratio and acetylene yield significantly rise, and product gas are refined into
This and energy consumption are substantially reduced；Whole device acetylene energy consumption reduction by more than 50%, close to natural gas etc. from
Daughter is pyrolyzed the energy consumption of acetylene processed.
Specific embodiment
The present invention is illustrated with following examples.
Embodiment, coal is continuously added to from the preceding charging aperture of helical feed reactor, and is added from laggard material mouth
The hot semicoke hybrid reaction of high temperature circulation.In helical feed reactor outlet high temperature pyrolysis gas and semicoke gas-solid
Separate.The pyrolysis gas of ^or-sotrc introduce the plasma reactor conduct of producing acetylene by plasma pyrolysis
Pyrolysis feed, low energy consumption ground production acetylene.High warm semicoke part enters burner heat cycles as coal
The high temperature heat source of fast pyrogenation, quality raw materials or production desulfurization of the remainder warm semicoke high as gasification
Agent and adsorbent.
