Description
Technical field
The invention belongs to coals to process field of comprehensive utilization, be related to a kind of upright as the external-heat of quenching mode using coal gas
Distillation process and its upright destructive distillation device of external-heat.
Background technology
Quenching refers to the process of that the high-temperature coke that will be obtained in retort process is cooled to the temperature for being readily transported and storing, right
It can be divided into two kinds of Dry Quenching and wet quenching again in upright gas retort.Wherein, Dry Quenching is the coal gas generated with retort section
High-temperature coke cooling heel row is removed into coke oven, wet quenching is directly to cool down to high-temperature coke by water spray.
Northwest China area low-disintegration coal charcoal is resourceful, such moisture content of coal and volatile matter content are high, are highly suitable as
The raw material of low temperature distillation, to produce tar, coal gas and semicoke.It is uprightly done currently, domestic enterprise mostly uses internal heat type low-temperature dry distillation
Technique is evaporated, the wherein high temperature needed for retort section is mixed and burned with oxygen rich gas by self-produced coal gas and provides, and quenching section is then direct
Cooled down using water at low temperature STRENGTH ON COKE.
Although existing low temperature distillation technique technology maturation, reliable for operation, the problem of all various aspects is still remained：
(1) internal heat type destructive distillation is whole because, containing more oxygen, keeping oxycarbide content in the coal gas of generation higher in system
Body heat value is relatively low.
(2) internally heated retort oven heats coal with air burning using the self-produced coal gas of retort process so that big
Part coal gas needs to flow back into retort section, and gas yield is made to decline.
(3) exhaust gas that gas-fired generates can be mixed into newly generated coal gas, not only further decrease the calorific value of coal gas,
Increase the cost of later separation and purified treatment.
(4) wet quenching is used, not only the local valuable water resource of waste, the quenching waste water of generation will also result in serious
Environmental problem.In addition, semicoke after cooling also needs to be further dried, to remove extra moisture.
(5) a large amount of steam that wet quenching generates are directly discharged in air, cause the waste of semicoke sensible heat.According to meter
It calculates, often refines heat about 2.21~2.35GJ that 1 ton of semicoke needs and accounted for wherein because of the heat about 1.05GJ that wet quenching is taken away
The 45% of total amount of heat.
In addition, the raw material that the internal thermal upright gas retort of Technical comparing maturation uses both at home and abroad must be 20~120mm
Lump coal reduces pressure drop, ensures the even running of device in order that improving the venting capability in coal seam in stove.As mechanization is adopted
The yield of the development of coal, fine coal gradually increases, and this part fine coal can not use traditional internal thermal upright furnace technology to handle, and make
At a large amount of wastes of resource.It is compared with internal thermal upright stove, external-heat upright furnace has a clear superiority in terms of handling fine coal：
The coal gas used as heat-source Cycles will not be directly entered in the coal seam of retort section, reduce the gas output of retort section, pressure drop is not
It can be significantly raised；Coal seam is slowly moved down by its own gravity, and movement is more gentle, reduces the fine coal generated by the friction between coal cinder
Amount；Due to not having inert gas introducing, coal gas active principle is high, and yield reduces, and flows through the narrow-minded of coal seam, reduces because of air-flow
Impact the coal amount generated.
