Abstract
The utility model is related to a kind of novel coke oven combustion chamber flue structure, include flue partition by being oppositely arranged and the carbonization chamber wall being oppositely arranged surround after the flue that forms；Both sides carbonization chamber wall upper edge height in the flue forms snakelike flue high temperature gas passage to multiple bulge-structures outstanding into flue, and the bulge-structure interval setting on the carbonization chamber wall of both sides is uniformly provided with；The utility model 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, to reduce the amount of nitrogen oxides in stack gases.
Description
Technical field
The utility model is related to coking by coke oven technical field more particularly to a kind of novel coke oven combustion chamber flue knots
Structure.
Background technology
Growing with coking industry, more and more technical staff start to be conceived to energy saving and improve ring
The research of guarantor's standard etc.；As country is increasingly stringenter the limitation of the toxic component oxynitrides in coking exhaust gas,
And stringent execution standard has been formulated, coal chemical enterprise is faced with shutout and stops production or rectify and improve inevitable choice up to standard.
Studies have shown that nitrogen oxides is mainly derived from the height for helping the nitrogen in gas-air to be carried out with oxygen in coke oven exhaust gas
Temperature reaction, i.e., so-called response type nitrogen oxides.And response type nitrogen oxides is drastically increased as reaction temperature increases, about
Logarithmic relationship is presented, therefore under the requirement for ensureing coke maturation, realization is evenly heated, reduces the ignition temperature of combustion high temperature point
It is the effective ways for reducing amount of nitrogen oxides.Uniform heating temperature can also reduce energy consumption simultaneously, avoid coke product local
Overheat, improves the economic benefit of product quality.
Invention content
The utility model provides a kind of novel coke oven combustion chamber flue structure, being capable of change burning room flue gas
It flows away to the raising thermal efficiency improves combustion chamber height to heating uniformity, reduces high temperature dot ignition temperature, useless to reduce flue
Amount of nitrogen oxides in gas.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of novel coke oven combustion chamber flue structure includes flue partition by being oppositely arranged and is oppositely arranged
The flue that carbonization chamber wall forms after surrounding；Both sides carbonization chamber wall upper edge height in the flue is multiple to vertical to being uniformly provided with
Bulge-structure outstanding in quirk, and the bulge-structure interval setting on the carbonization chamber wall of both sides, form snakelike flue high temperature
Gas passage；
Snakelike flue high temperature gas passage can change the flow regime of high-temperature gas in flue, and part becomes laminar flow
For turbulent flow, to enhancing heat transfer, improve heat transfer efficiency, increase the high temperature dot in flue, so improve flue height to
Heating uniformity is more advantageous to the uniformly ripening of coke；The temperature of combustion high temperature point is reduced under the premise of not changing coking time
Degree, to reduce the content of nitrogen oxides of exhaust gas.
From being formed to the polylith wall brick built by laying bricks or stones along height, the wall brick of bulge-structure and respective heights is integrated the carbonization chamber wall
Structure.
The bulge-structure protrudes from 1/5~1/3 that the length except carbonization chamber wall is flue corresponding direction width.
Compared with prior art, the utility model has the beneficial effects that：
1) compared with existing vertical unobstructed combustion chamber flue, the flowing of burning gases in flue can be changed
State greatly increases the turbulent flow ratio of flowing gas, 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 advantageous to coke
Uniformly ripening；
3) temperature that combustion high temperature point is reduced under the premise of not changing coking time, to reduce nitrogen oxides of exhaust gas
Content, reduce energy waste and environmental pollution, mitigate the environmental protection pressure of coal chemical enterprise；
4) under the premise of not changing coal gas infeed amount, the temperature of discharge exhaust gas can be reduced, shortens coking time, is improved single
Yield in the time of position.
Description of the drawings
Fig. 1 is a kind of schematic diagram of novel coke oven combustion chamber flue structure described in the utility model.
In figure：1. 4. coke of flue 2. carbonization chamber wall, 3. wall brick, 5. bulge-structure
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of novel coke oven combustion chamber flue structure described in the utility model, including by being oppositely arranged
Flue partition and the carbonization chamber wall 2 that is oppositely arranged surround after the flue 1 that forms；Both sides charing in the flue 1
Wall 2 upper edge height in room is to being uniformly provided with multiple bulge-structures 5 outstanding into flue 1, and the protrusion knot on both sides carbonization chamber wall 2
The setting of the interval of structure 5, forms snakelike flue high temperature gas passage；
Snakelike flue high temperature gas passage can change the flow regime of high-temperature gas in flue 1, local change layer
Stream is turbulent flow, to enhancing heat transfer, improves heat transfer efficiency, increases the high temperature dot in flue 1, and then improve flue 1
Height is more advantageous to the uniformly ripening of coke 4 to heating uniformity；Combustion high temperature point is reduced under the premise of not changing coking time
Temperature, to reduce the content of nitrogen oxides of exhaust gas.
From being formed to the polylith wall brick 3 built by laying bricks or stones along height, bulge-structure 5 and the wall brick 3 of respective heights are the carbonization chamber wall 2
Integral structure.
The bulge-structure 5 protrudes from 1/5~1/ that the length except carbonization chamber wall 2 is 1 corresponding direction width of flue
3。
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
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.
