Abstract
The present invention relates to pyrolysis technology, and is especially method of pyrolyzing solid heat carrier in circular fluidizing bed and rotary kiln. The present invention features that the material to be pyrolyzed and the solid heat carrier mixture is heated in the rotary kiln to pyrolyze, the pyrolyzed semi-coke and the bed material are conveyed with the conveyer from the rotary kiln to the circular fluidizing bed to burn, the bed material after heating is separated in the gas-solid separator, and the separated solid particle as the solid heat carrier is returned through the vertical pipe and the non-mechanical valve to the pyrolysis furnace in the rotary kiln. The present invention utilizes the low grade heat source fully to raise heat efficiency.
Description
Technical field
The invention belongs to the pyrolytic technique field, relate to a kind of circulating fluidized bed and rotary kiln of utilizing and carry out thermoset carrier pyrolytic method.
Background technology
According to the assessment of the world energy sources council/International Institute for Applied Systems Analysis, the fossil oil reserves that global cost of winning is lower will exhaust to latter stage in mid-term in this century.According to the law of conservation of matter and law of conservation of energy, in the long run, the problem of some resource absolute scarcity will inevitably appear in the world.Therefore, the key that solves energy dilemma is the breakthrough of energy novel material and taps a new source of energy, and actively utilizes the renewable energy resources.
Rotary kiln thermoset carrier technology is mainly used in the pyrolysis of solid organic matter and produces oil fuel.In the internal heat type rotary kiln, decomposed fast by the heat effect of thermoset carrier after the fragmentation of SOLID ORGANIC matter (500 ℃ Zhao 800 ℃), after separating, the oil gas that pyrolysis produces to obtain pyrolysis oil and middle calorific value combustible gas in gas-liquid separator, semicoke after the pyrolysis is sent into circulating fluidized bed combustion stove burning through e Foerderanlage, and the heat that coal-char combustion produces adds hott bed material (800 ℃ Zhao 900 ℃) and reenters rotary kiln as thermoset carrier through the material circulating system of circulating fluidized bed.Traditional rotary kiln pyrogenation technology mainly contains internal heat type and external-heat technology, and internal heat type technology is difficult to processing and utilizes because combustion processes is carried out in kiln, and products of combustion has significant dilution and polluting effect to pyrolysis product, makes that the pyrolysis product quality is low.And external-heat process heat efficient very low (being approximately 30%-40%), the energy consumption height, complex process is difficult to extensive operation, seldom adopts.
Summary of the invention
The purpose of this invention is to provide a kind of circulating fluidized bed and rotary kiln of utilizing and carry out thermoset carrier pyrolytic method.
Technical scheme of the present invention is that the pyrolysis material enters rotary kiln from charging opening, is that 800-900 ℃ red-hot bed material (thermoset carrier) mixes the intensification pyrolysis in rotary kiln and temperature, and pyrolysis gas-liquid product enters gas-liquid separator, processes after the separation and utilizes.Pyrolysis material in the rotary kiln constantly moves to outlet section under the rotation of rotary kiln when pyrolytic reaction takes place, sends into ciculation fluidized burning bed by e Foerderanlage after pyrolysis char and bed material leave rotary kiln.Pyrolysis char is after the circulating fluidized bed internal combustion adds the hott bed material, entering gas-solid separator with the bed material separates, solid particulate is separated to get off, and reenters the rotary kiln pyrogenation stove as thermoset carrier through standpipe and on-mechanical valve, and flue gas and minute quantity fine particle are discharged by separator outlet.
Effect of the present invention and benefit are:
(1) the present invention can solve the low problem of internal heat type technology pyrolysis product quality well, can overcome the inefficient weakness of external-heat process heat again, can realize efficient, cleaning pyrolysis to organic matter.
(2) the present invention utilizes two kinds of technology separately by the combining of rotary kiln and circulating fluidized bed technique
Advantage, combustion and pyrolysis semicoke and add hott bed material (thermoset carrier) in circulating fluidized bed, the bed material recycle system by circulating fluidized bed is transported to thermoset carrier in the rotary kiln pyrogenation stove, red-hot bed material in rotary kiln under the disturbance of the rotation of rotary kiln and inner member, with the organic thorough mixing heat exchange that enters in the rotary kiln, make organic matter that fast pyrogenation take place, inflammable gas that produces and tar obtain recycling, and the bed material of semicoke and release of heat is sent the circulating fluidized bed combustion heat temperature raising again back to.
(3) the present invention separately carries out the burning of semicoke and the pyrolysis of raw material, is realizing the thermoset carrier pyrolytic simultaneously, makes full use of the low-quality energy in the pyrolysis char as the pyrolysis thermal source, need not increase the pollution to pyrolysis product simultaneously.Utilize the advantage separately of circulating fluidized bed and rotary kiln, have the thermo-efficiency height, characteristics such as technology is simple.
Description of drawings
Accompanying drawing is a workflow diagram of the present invention.
Embodiment
Below in conjunction with technical scheme and accompanying drawing, be described in detail specific embodiments of the invention.
Embodiment:
The resinous shale material enters rotary kiln from charging opening, is that 800-900 ℃ red-hot bed material (thermoset carrier) closes the intensification pyrolysis in rotary kiln and temperature, and pyrolysis oil and a small amount of pyrolysis gas enter gas-liquid separator, processes after the separation and utilizes.Resinous shale in the rotary kiln constantly moves to outlet section under the rotation of rotary kiln when pyrolytic reaction takes place, sends into ciculation fluidized burning bed by e Foerderanlage after pyrolysis char and bed material leave rotary kiln.Pyrolysis char is after the circulating fluidized bed internal combustion adds the hott bed material, entering gas-solid separator with the bed material separates, solid particulate is separated to get off, and reenters the rotary kiln pyrogenation stove as thermoset carrier through standpipe and on-mechanical valve, and flue gas and minute quantity fine particle are discharged by separator outlet.
