Description
Technical field:
The utility model relates to producer gas generator, particularly a kind of single outlet producer gas generator with retort section.
Background technology:
Atmospheric fixed bed gas-producer commonly used now mainly is one-part form producer gas generator and two stage type gas generating furnace.
1. one-part form producer gas generator gasification bituminous coal is produced the shortcoming of heating gas:
(1) the big problem of coal dust amount
1. the one-part form producer gas generator need keep the dead level of 1500-2000mm when operation, and the drop of coal is bigger during coal, a large amount of coal dusts of kicking up.
2. the one-part form producer gas generator belongs to low bed of material operation, the drying and carbonization of coal and gasification are all carried out in a very thin bed of material (800-1100mm), and cold coal charge contacts the hyperthermia radiation of temperature up to 600-700 ℃ after going into stove immediately, make coal cause thermal explosion easily, produce coal dust.
3. the one-part form producer gas generator need be visited pricker when operation, also needs sometimes to poke fire, and these operations can stir a large amount of coal dusts.
(2) tar problem
Because the one-part form producer gas generator belongs to low bed of material operation, the drying and carbonization of coal and gasification, all at a very thin bed of material, the heavy tar that makes bituminous coal produce Pintsch process is taken out of with coal gas, and this part tar viscosity is bigger, and is mobile poor, easily precipitation.
More than coal dust of Chan Shenging and tar all enter gas line with coal gas, and on the one hand because the generation of coal dust has caused the waste of the energy, coal-tar middle oil and dust deposit influences ordinary production in heating gas pipeline, valve, burner owing to coal gas on the other hand.And tornado dust collector and the tar that gets off from pipe sedimentation can't utilize, thereby cause environmental pollution.
(3) gas furnace complicated operation problem
The dead level that the one-part form manipulation require is kept certain height, general height 1500-2000mm need judge adjustment according to the working of a furnace, acquires a certain degree of difficulty.
2. two stage type gas generating furnace shortcoming:
Two sections stoves are to have increased a retort section on the basis of primary reformer, the low-temperature pyrolysis and the gasification of coal are combined, segmentation is carried out in a body of heater, the coal gas part that gasification section is produced derives from the hypomere outlet then, another part is used for destructive distillation and goes into the stove coal charge, and derives from the epimere outlet together with the coal gas that the coal charge low-temperature pyrolysis produces.
(1) the big problem of coal dust amount
1. cause thermal explosion easily for the relatively poor coal of thermostability, produce coal dust and take out of with hypomere coal gas.
2. need visit pricker when operation, also need sometimes to poke fire, these operations can stir a large amount of coal dusts and take out of with hypomere coal gas.
(2) gas furnace complicated operation problem
In the operation of two sections stoves, on, the adjusting of hypomere gas flow is extremely important, because if the up amount of coal gas too small (external manifestation is that the gas in upper segment flow is little) that gasification section produces, be used for pyrogenous shortage of heat, the coal destructive distillation is insufficient, certainly will cause hypomere coal gas to contain a large amount of Pintsch gas tars, for avoiding above situation to take place, this just requires on Process configuration, must increase a coal gas of high temperature variable valve at hypomere gas exit place, last hypomere coal gas suitably be regulated, and will be waited for 10 hours and just can find out regulating effect later on, if undesirablely also need readjust, producer gas generator complicated operation degree is increased.
(3) gas furnace is invested high problem
Two stage type gas generating furnace retort section complex structure, investment strengthens.
Summary of the invention:
Goal of the invention of the present utility model aims to provide a kind of single outlet producer gas generator with retort section, and the tar flowability that always perplexs the gas furnace widespread use is poor, coal gas is taken problems such as the coal dust amount is big thereby solve, and this type of furnace is simple to operate, invests low.
The technical scheme that realizes the foregoing invention purpose is: single outlet producer gas generator of band retort section comprises bottom construction, gasification section, stoker, dust removing machine, be disposed with retort section and coal section between this gasification section and the stoker from bottom to top, this retort section is made up of outer cylinder body and liner, be the awl core structure, up-small and down-big; This coal intersegmental part is provided with branch coal device and coal location probe, this minute the coal device be multi-tube structure, this coal location probe is arranged on the upper orifice place of this multi-tube structure, this coal section side is provided with a gas exit.
Single outlet producer gas generator of this band retort section that realizes according to this case is compared with two stage type gas generating furnace with existing one-part form producer gas generator, has following advantage and effect:
1. this producer gas generator is in full bed of material operation for a long time, and coal charge slowly moves down, and the dust when avoiding coal flows out with coal gas; In addition, the coal dust that furnace bottom gasification section coal charge thermal explosion and operation produce when visiting pricker filters through thick destructive distillation layer, all is deposited on to be used for gasification in the coal charge.
2. this producer gas generator is used for gas temperature that the bottom gasification section of destructive distillation coal charge produced within 550～600 ℃ of scopes, and coal carbonization belongs to low-temperature pyrolysis in the retort section.
3. this producer gas generator belongs to the producer gas generator of full bed of material operation, single gas exit, both overcome primary reformer in operating aspect and need control the problem that dead level is operated, overcome two sections stoves again and need adjust the problem of hypomere coal gas ratio, simple to operate, invest lowly.
