Description
Technical field
The utility model is related to star-like arcuately distribution device, and in particular to a kind of great Rong with star-like arcuately distribution device
Gauging shale retorting circular furnace.
Background technology
Oil shale is a kind of reserves very abundant but the resource not being well utilised.Global oil shale is converted to page
Shale oil is up to more than 4,000 hundred million tons, and crude oil reserve is verified more than more than 1,700 hundred million tons far beyond the world.China's oil shale prediction up to 719,900,000,000
Ton, is converted to shale oil resource for 47,600,000,000 tons.
Domestic existing dry distrillation apparatus for oil shale mainly has the gas combustion of Fushun half to do based on gas heat carrier destructive distillation mode
Furnace, the full gas combustion retort in Maoming and Huadian formula gas retort.
The gas combustion retort of Fushun half is when carrying out retorted shale, and required thermal source, which comes from cycling hot gas and stove, to gasify
Gasification gas produced by section Pyrolysis Char and air imperfect combustion, and thermal source needed for the full gas combustion retort in Maoming entirely from
Heat smoke produced by destructive distillation gas combustion.Contain a large amount of nitrogen and titanium dioxide in gas produced by two kinds of distillation process
Carbon, greatly reduces gas calorific value, also have impact on destructive distillation oil yield.
Huadian gas retort then carries out oil-shale retorting using gas full circulation technology, the heat carrier used entirely from
Cycling hot gas, the hot gas does not have combustion reaction, and contained nitrogen and carbon dioxide are few, and gas calorific value is high, simultaneously because stove
Interior no combustion reaction, is less prone to local overheating in stove, oil yield is higher.Single heat size of Huadian gas retort is at present
300t/d。
According to the existing design feature of Huadian gas retort, there is certain office in its distributing mode, gas distribution mode and coke discharging
It is sex-limited.
1. distributing mode be single battle array umbrella cloth material, i.e. gas retort top using single battle array umbrella by material circumferentially, battle array
Umbrella centrally under occurs without material space, that is, being presented middle low, the high phenomenon of surrounding.In order to alleviate this material position out-of-flatness, birch
Pasture stove arranges that two layers of herringbone plate carries out quadratic distribution to material in battle array umbrella lower part.This distributing mode is done to smaller part reason amount
For furnace, cloth uneven phenomenon is not obvious.But as treating capacity increases, gas retort internal diameter is also with increase, single battle array umbrella knot
Requirement can not be met by closing the distributing mode of herringbone plate.
Outwards sprayed 2. the gas distribution mode of Huadian gas retort employs the periphery that hot gas puts along ancient cooking vessel shape dress, cold gas is along cold
Circulating mash gas enters the intake method of gas retort from the SAPMAC method gas inlet tube for the bottom for being arranged at stove
(CN201010237472.0, page 9), the section of burner hearth of 300t/d stoves is smaller, and air-flow is easier to be full of in whole cross section, stove and cut
Face temperature uneven phenomenon is not obvious.But as treating capacity increases, gas retort inner section also increases therewith, heat watt under the gas distribution mode
This air-flow can not be uniformly filled in whole cross section in stove, easily cause the exacerbation of section temperature uneven phenomenon.
3. the coke discharging mode of Huadian gas retort employs conventional wet coke discharging mode, the gas leakage of body of heater coke discharging is solved with water seal
Problem, the coke discharging mode is also equally used by domestic and international all gas heat carrier gas retort.The not high semicoke increase of script calorific value
After moisture, the calorific value of semicoke is remarkably decreased, and burning is using valueless.
