Description
Technical Field
The utility model relates to a coke oven technical field especially relates to a locate in the vertical flue, have the lamp holder brick of multistage export.
Background
The coke oven is composed of regenerator, chute, combustion chamber, charring chamber and top. The coal gas and the air are mixed and combusted in the combustion chamber, and heat is transferred to the coal in the carbonization chamber in a heat conduction and heat radiation mode, so that the coal is converted into coke. The thermal regulation of the coke oven comprises the regulation of the heating temperature in the long direction and the heating temperature in the high direction, and the uniform temperature distribution of the oven wall of the carbonization chamber, thereby not only saving the fuel, but also preventing the oven body of the coke oven from being damaged due to local overheating. At present, the high-direction heating uniformity of the coke oven is adjusted by adopting the modes of waste gas circulation, multi-section heating, high and low lamp holders and the like in a large coke oven.
The coke oven gas outlet pipe brick at the bottom of the vertical flue is called a lamp cap brick (or a burner brick). The lamp cap brick has the function of ensuring that the gas is reasonably combusted when the coke oven gas is used for heating, so that the coke cake is uniformly heated in the height direction. In general, the top surface of the lamp head brick is flush with or slightly higher than the bottom surface of the vertical flue, which is called a low lamp head, and the top surface of the lamp head brick is higher than the exhaust gas circulation hole, which is called a high lamp head. The high-low lamp head is characterized in that outlets of heating coal gas in two adjacent vertical flame paths in the combustion chamber are arranged at different heights from the bottom of the carbonization chamber, so that the heating conditions of the upper part and the lower part of the combustion chamber are slightly improved.
Disclosure of Invention
The utility model provides a lamp holder brick with multistage export for supply coke oven gas along founding the flame path height to the segmentation, be favorable to lengthening the flame in the founding the flame path, improve the coke oven height to heating homogeneity, reduce heating gas consumption and nitrogen oxide formation volume, realize source energy saving and emission reduction's purpose, have good economic benefits and environmental benefit, be worth promoting.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a lamp holder brick with a plurality of sections of outlets is arranged at the bottom of a vertical flue, a gas inlet is arranged at the bottom of the lamp holder brick and is connected with a gas channel on a gas pipe brick in a chute area, at least 2 gas outlets are arranged at the top of the lamp holder brick, and the heights of the gas outlets are different.
The sectional areas of the coal gas outlets are the same or different.
The cross section of each coal gas outlet is circular, oval or polygonal.
Each coal gas outlet is vertically and upwards arranged, and the height of the coal gas outlet at the lowest part is higher than the height of the upper edge of the waste gas circulating hole.
And each gas outlet is provided with an adjusting brick or a plug brick.
Compared with the prior art, the beneficial effects of the utility model are that:
1) the lamp holder brick has simple structure and is easy to build;
2) the coke oven can be used in a newly-built coke oven and can also be used in a reformed coke oven;
3) the lamp holder brick is provided with a plurality of gas outlets with different heights, which is beneficial to lengthening flame in the vertical flue, improving the height direction heating uniformity of the coke oven, reducing the consumption of heating gas and the generation of nitrogen oxides, realizing the purpose of energy conservation and emission reduction at the source and having good economic benefit and environmental benefit.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1 and 2, the utility model relates to a lamp holder brick with multistage export, lamp holder brick 4 is located and is found flame path 5 bottom, and the bottom of lamp holder brick 4 is equipped with a coal gas entry 41 and links to each other with the coal gas path on the ramp district 1 coal gas pipe brick 7, and the top of lamp holder brick 4 is equipped with 2 at least coal gas exports 42, and each coal gas export 42's height difference.
The cross-sectional area of each gas outlet 42 is the same or different.
The cross-sectional shape of each gas outlet 42 is circular, oval or polygonal.
Each coal gas outlet 42 is vertically and upwards arranged, and the height of the coal gas outlet 42 at the lowest part is higher than the height of the upper edge of the waste gas circulating hole 3.
And an adjusting brick or a plug brick is arranged at each gas outlet 42.
As shown in figure 3, two sides of the vertical flue 5 are separated from the adjacent carbonization chambers by combustion chamber walls 6, and the bottom surface of the vertical flue 5 is flush with the bottom surface 2 of the carbonization chambers. The bottom of the vertical flue 5 is connected with the regenerator through the chute area 1, and the bottom of the vertical flue 5 is provided with an exhaust gas circulation hole 3 and a lamp holder brick 4. The utility model relates to a lamp holder brick with multistage export, a plurality of coal gas export 42 on the lamp holder brick 4 are located different level, coal gas gets into from the coal gas export 42 of different height and founds flame path 5 and air hybrid combustion.
