Technical field
The utility model is related to lump coal carbonization and prepares semi-coke technology, and in particular to a kind of internal heat type semi-coke stove.
Background technology
Traditional semi-coke stove is due to using air as combustion-supporting gas, and reuse coal gas is as fuel, hot gas after gas-fired
Body causes nitrogen content and carbon dioxide content in semi-coke stove by-product gas too high as the thermal source and heat carrier of semi-coke destructive distillation,
Pyrolyzing coal is so incensed that dilution, and calorific value declines, and value reduction easily causes environmental pollution.
If combustion air is changed into oxygen, oxygen cost processed directly affects the economic benefits of gas retort, while easily hair
Raw explosion accident.Use carbon dioxide for heat carrier there is also cost it is high the problem of.
If heated using traditional regenerator, transformed for existing semi-coke stove, coal gas of high temperature inlet height is too low, in order to
Regenerator height is not reduced, it is necessary to which regenerator body of heater is placed in into below ground, it is necessary to increase new civil engineering, causes certain difficulty
Degree.
The honeycomb ceramic heat accumulator of high surface area is such as used, reduction regenerator height then occurs that commutating period is too short, changes
To frequent, reversal valve is fragile, is mixed into exhaust gas volumn increase, flue gas in coal gas and is mixed into the problems such as not having tolerance increase.
Regenerator height problem can be solved using coal gas down-comer, but high temperature change-over valve there is gas leakage, it is cold
But a series of safety problems such as system complex and commutation mechanical breakdown, directly affect the industrialization longtime running of coal gas complete alternation
Economy and security.
If taking concentration gas heating system, although reduce high temperature reversal valve, but according to the market supply and demand, flexibly adjust
The operation number of units and yield for saving semi-coke stove are restricted；Designed using distributed coal gas complete alternation, a fairly large number of coal gas of high temperature
How reversal valve therefore cancels coal gas of high temperature reversal valve into the significant obstacle of course of industrialization, is the heating of semi-coke stove regenerator
The problem of coal gas full circulation technology transformation.
