Abstract
The present invention relates to a kind of new coke oven combustion chamber flue structure, including the flue formed after being surrounded by the flue partition being oppositely arranged and the carbonization chamber wall being oppositely arranged；Along height to multiple bulge-structures prominent into flue, and the bulge-structure interval setting on the carbonization chamber wall of both sides is uniformly provided with both sides carbonization chamber wall in the flue, snakelike flue high temperature gas passage is formed；The present invention can change burning room flue air-flow trend, improve the thermal efficiency, improve combustion chamber height to heating uniformity, high temperature dot ignition temperature is reduced, so as to reduce the amount of nitrogen oxides in stack gases.
Description
Technical field
The present invention relates to coking by coke oven technical field, more particularly to a kind of new coke oven combustion chamber flue structure.
Background technology
Growing with coking industry, increasing technical staff, which starts to be conceived to, to be saved the energy and improves ring
The research of guarantor's standard etc.；As limitation of the country to the toxic component oxynitrides in coking waste gas is more and more stricter,
And strict execution standard has been formulated, coal chemical enterprise is faced with shutout and stops production or rectify and improve inevitable choice up to standard.
Research shows that nitrogen oxides is mainly derived from the height that the nitrogen helped in gas-air is carried out with oxygen in coke oven exhaust gas
Temperature reaction, i.e., so-called response type nitrogen oxides.And response type nitrogen oxides drastically raises as reaction temperature raises, about
Logarithmic relationship is presented, therefore in the case where ensureing the ripe requirement of coke, realizes uniformly heating, reduces the ignition temperature of combustion high temperature point
It is the effective ways for reducing amount of nitrogen oxides.Uniform heating-up temperature can also reduce energy consumption simultaneously, avoid coke product local
Overheat, improve the economic benefit of product quality.
The content of the invention
The invention provides a kind of new coke oven combustion chamber flue structure, can change burning room flue air-flow walk
To the raising thermal efficiency, improvement combustion chamber height reduces high temperature dot ignition temperature, so as to reduce in stack gases to heating uniformity
Amount of nitrogen oxides.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of new coke oven combustion chamber flue structure, including by the flue partition being oppositely arranged and be oppositely arranged
The flue that carbonization chamber wall forms after surrounding；It is multiple to vertical along height to being uniformly provided with both sides carbonization chamber wall in the flue
Prominent bulge-structure in quirk, and the bulge-structure on the carbonization chamber wall of both sides is arranged at intervals, and forms snakelike flue high temperature
Gas passage；
Snakelike flue high temperature gas passage can change the flow regime of high-temperature gas in flue, local to become laminar flow
For turbulent flow, so as to enhancing heat transfer, improve heat transfer efficiency, increase the high temperature dot in flue, so improve flue height to
Heating uniformity, it is more beneficial for the uniformly ripening of coke；The temperature of combustion high temperature point is reduced on the premise of coking time is not changed
Degree, so as to reduce the content of nitrogen oxides of exhaust gas.
From being formed along height to the polylith wall brick built by laying bricks or stones, the wall brick of bulge-structure and respective heights is integrated the carbonization chamber wall
Structure.
The length that the bulge-structure protrudes from outside carbonization chamber wall is the 1/5~1/3 of flue correspondence direction width.
Compared with prior art, the beneficial effects of the invention are as follows：
1) compared with existing vertical unobstructed combustion chamber flue, the flowing of burning gases in flue can be changed
State, the turbulent flow ratio of flowing gas is greatly increased, so as to improve the heat transfer efficiency of high-temperature gas；
2) increase localized hyperthermia's point in flue, and then improve flue height to heating uniformity, be more beneficial for coke
Uniformly ripening；
3) temperature of combustion high temperature point is reduced on the premise of coking time is not changed, so as to reduce nitrogen oxides of exhaust gas
Content, reduce energy waste and environmental pollution, mitigate the environmental protection pressure of coal chemical enterprise；
4) on the premise of coal gas infeed amount is not changed, the temperature of discharge waste gas can be reduced, shortens coking time, is improved single
Yield in the time of position.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of new coke oven combustion chamber flue structure of the present invention.
In figure：1. the bulge-structure of 4. coke of flue 2. carbonization chamber wall, 3. wall brick 5.
Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of new coke oven combustion chamber flue structure of the present invention, including it is vertical by what is be oppositely arranged
Quirk partition wall and the carbonization chamber wall being oppositely arranged is 2-in-1 enclose after the flue 1 that forms；Both sides carbonization chamber wall 2 in the flue 1
On along height to being uniformly provided with multiple bulge-structures 5 prominent into flue 1, and between the bulge-structure 5 on both sides carbonization chamber wall 2
Every setting, snakelike flue high temperature gas passage is formed；
Snakelike flue high temperature gas passage can change the flow regime of high-temperature gas in flue 1, local change layer
Flow for turbulent flow, so as to enhancing heat transfer, improve heat transfer efficiency, increase the high temperature dot in flue 1, and then improve flue 1
It is high to heating uniformity, be more beneficial for the uniformly ripening of coke 4；Combustion high temperature point is reduced on the premise of coking time is not changed
Temperature, so as to reduce the content of nitrogen oxides of exhaust gas.
From being formed along height to the polylith wall brick 3 built by laying bricks or stones, bulge-structure 5 and the wall brick 3 of respective heights are the carbonization chamber wall 2
Integrative-structure.
The length that the bulge-structure 5 protrudes from outside carbonization chamber wall 2 is the 1/5~1/ of the correspondence direction width of flue 1
3。
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
