Description
Technical field
The utility model relates to low order fine coal retorting technique field more particularly to a kind of destructive distillation for low order fine coal destructive distillation
Furnace gas aggregating apparatus.
Background technique
The low coal of low-order coal, that is, degree of coalification, the coal quality is low, and in China, distribution is wide, and yield is big.In low order coal mining
A large amount of fine coal can be generated in the process (granularity is in 13mm coal below).Using external-heat low order fine coal gas retort to low order fine coal
When carrying out destructive distillation, the raw coke oven gas generated in gas retort has to just be exported across the fine coal bed of material.When raw coke oven gas passes through fine coal
When the bed of material, since the density of fine coal is big, gap is small, the fine coal bed of material can form biggish resistance to the flowing of raw coke oven gas, so that waste
Coal gas is difficult to be discharged out of destructive distillation room in time, excessively high so as to cause destructive distillation room pressure, can cause to damage to destructive distillation furnace wall when serious
Evil.In addition, the raw coke oven gas with tar light oil ingredient that destructive distillation generates cannot such as be exported in time in destructive distillation room, height can be caused
Anneal crack solution, this will reduce tar light oil ingredient in raw coke oven gas, and tar yield be reduced, to reduce the integral benefit of gas retort.Mesh
Before, frequently with the mode of the appropriate location setting gas collecting apparatus in destructive distillation room in low order fine coal gas retort, by raw coke oven gas from dry
Evaporate indoor export.Therefore, gas collecting apparatus is the core equipment of low order fine coal gas retort, is not provided with gas collecting apparatus, and low order fine coal is dry
Evaporating just cannot achieve.
Existing gas collecting apparatus common form is that (such as application No. is 201510468064.9 China specially for circular train of dress formula
One kind disclosed in benefit " gas collecting apparatus in carbonization chamber "), due to the limitation of this body structure, the raw coke oven gas entrance on gas collecting tube can not
It designs very big, finds in production practice, the dust that the raw coke oven gas entrance on gas collecting tube can be carried in raw coke oven gas quickly is complete
It blocks, is collected and derived function so that gas collecting apparatus be made to lose raw coke oven gas entirely.
Through analyzing, since the indoor coal charge of destructive distillation moves from the top down, the indoor coal charge temperature of destructive distillation is also from upper
Gradually risen under and, thus in destructive distillation room top coal charge temperature it is lower (lower than the dew point of water).It is collected when gas collecting apparatus
When high temperature raw coke oven gas moves upwards from bottom to top, heat exchange occurs for the upper section inner wall of raw coke oven gas and gas collecting apparatus, big in raw coke oven gas
The vapor and sub-fraction tar condensing of amount are liquid.These liquids have very strong caking property, and take in raw coke oven gas
The dust of band is bound together on the inner wall of gas collecting apparatus.Over time, the air inlet of gas collecting apparatus it is even internal by
Gradually material to be bonded blocks, and gas collecting apparatus just loses raw coke oven gas collection and derived function, to influence the peace of gas retort production
Row for the national games, while the yield of tar is also reduced, reduce the integral benefit of gas retort.
Summary of the invention
The utility model provides gas collection device in a kind of gas retort, can effectively prevent the generation of stopping state,
The raw coke oven gas for generating destructive distillation quickly, swimmingly exports, and ensures the safety and stabilization of the production of external-heat low order fine coal gas retort
Property, guarantee tar yield.
In order to achieve the above object, the utility model is implemented with the following technical solutions：
Gas collection device in a kind of gas retort, including collect supervisor and multiple collect umbrella；It is described collect supervisor hang vertically

2) contain coal gas, vapor, gaseous state tar and solid-state dust, raw coke oven gas in the raw coke oven gas generated after 4 destructive distillation of coal charge
Be collected into flow process collect umbrella 2 lower section, by collect umbrella 2 and diamond passages that seam 7 is formed in, then by collecting
Water-drop-shaped hole 6 on supervisor 1, which enters, to be collected in supervisor 1；
3) enter the raw coke oven gas for collecting supervisor 1 upwards through furnace roof gas gathering system export gas retort, and carried secretly in raw coke oven gas
Solid-state dust and the condensed drop separation of gas come out, due to collect supervisor 1 and collect umbrella 2 inner surface coat it is inorganic
Ceramic nano coating 3, dust, drop in raw coke oven gas can not be attached to above-mentioned surface, but slide along above-mentioned surface, pass through remittance
The lower ending opening of collection supervisor 1 imports in the coal charge 4 of lower part, and the coal charge 4 run down is taken away.
In the utility model, is collecting supervisor 1 and collecting the principle of spraying inorganic ceramic nano coating 3 on 2 inner wall of umbrella, be
By a kind of natural plant --- the inspiration of common nepenthes, the inner wall dead smooth of common nepenthes, any insect fallen can not all climb
Out.The surface dead smooth of inorganic ceramic nano coating 3 described in the utility model, that is to say, that its surface potential energy is very low,
When the surface that object is deposited in it reaches certain mass, and surface potential energy is not enough to overcome the gravity of accumulation object itself, object
Body will slide from its surface.The lower ending opening for collecting supervisor 1, the dust and drop slid along inner wall can fall to gas
On coal charge 4 below aggregating apparatus, the coal charge 4 run down is taken away.Inorganic ceramic nano coating 3 described in the utility model is
Commercial product, with high temperature resistant (~1000 DEG C), corrosion-resistant, performance with long service life.To apply the inorganic ceramic nanometer
Layer 3 is securely attached to collect supervisor 1 and collects the inner surface of umbrella 2, collects supervisor 1 and collects umbrella 2 after a group weldering completes
Surface has first carried out blasting treatment, and the inorganic ceramic nano coating of spraying is enable to collect supervisor 1 and collect the inner surface of umbrella 2
Firm attachment, to guarantee its durability.
Collect supervisor 1 to enter the raw coke oven gas being pooled to collect in umbrella 2 swimmingly, while collecting the waste coal on supervisor 1
Gas entrance will not be blocked by dust, collecting for 2 root of umbrella open up water-drop-shaped hole 6 on supervisor 1 collecting.This water-drop-shaped hole
6 can reduce the resistance of gas operation, and the area opened up due to water-drop-shaped hole 6 is sufficiently large (to compare existing train of dress formula gas collection
The entrance of device is much larger) so that the raw coke oven gas for carrying dust can enter here collects supervisor 1 much smootherly, avoid
Clogging.
Collect supervisor 1 to smoothly enter the raw coke oven gas being pooled to collect in umbrella 2, while considering gas collection device
The factors such as the structural strength of itself are groped by proving and testing repeatedly, and the angle α 1 for collecting umbrella 2 and horizontal plane is determined
12 °~15 °, the downward direct motion of coal charge 4 collected outside umbrella 2 had not only been taken into account in this way, but also had taken into account that collect 2 inside raw coke oven gas of umbrella upward
Direct motion has combined the structural strength of gas collection device itself.
Collect the top of umbrella 2 not stay in the coal charge 4 in destructive distillation room 5, collect the pinnacle angle [alpha] 2 of umbrella 2 itself≤
60 ° (less than the angle of repose of low order fine coal), to prevent ash erosion.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
