Description
Technical Field
The invention relates to the technical field of coke oven carbonization chambers, in particular to a staggered groove type coke oven carbonization chamber furnace end structure.
Background
Currently, the following problems are easy to be solved in the production operation process of the coke oven: in the coking process of the coke oven coking chamber, a large amount of raw coke gas is generated, and the raw coke gas accounting for 75-90% of the total yield of the raw coke gas flows upwards through a gap between a coke cake and a wall of the coking chamber and then is discharged out of the furnace from a riser, if the raw coke gas is not timely led out, the internal pressure of the coking chamber is excessively high, and the raw coke gas directly leaks into the atmosphere from a furnace door, so that the environment is polluted. Meanwhile, raw gas is not led out timely, so that heat exchange of coke at a furnace end part far away from one side of the rising pipe is affected, and coke maturity is affected.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a staggered groove type coke oven carbonization chamber furnace end structure. The raw gas is prevented from leaking into the atmosphere directly from the furnace door, and the environment is prevented from being polluted; effectively improves the maturity condition of the coke at the furnace end.
In order to achieve the above purpose, the invention is realized by adopting the following technical scheme:
The utility model relates to a staggered groove type coke oven carbonization chamber furnace end structure, wherein the wall surfaces on two sides of the furnace end part of the carbonization chamber are provided with staggered grooves; 1-3 grooves are formed in each layer of bricks on the wall surface, each 2-3 layers of bricks are circulated, and the grooves of the upper layer of bricks are staggered with the grooves of the lower layer of bricks; the grooves on the same layer of bricks on the wall surface on one side of the furnace end part of the carbonization chamber and the wall surface on the other side are distributed in a staggered way.
The distance between the groove and the vertical line of the coal charging effective position is 10-500 mm.
The grooves are square, triangular or semicircular, and all corner parts of the grooves are provided with round corners.
The grooves avoid the brick joints.
The depth of the groove is 5-15 mm.
The grooves are not higher than the coal loading height.
Compared with the prior art, the invention has the beneficial effects that:
1) In the high-temperature coking process, raw coke gas can flow upwards through a channel between a coke cake at the furnace end part of the carbonization chamber and a staggered groove on the wall surface of the carbonization chamber, and then is discharged out of the furnace from the ascending pipe, so that the raw coke gas is prevented from escaping from the furnace door and polluting the environment due to the fact that the pressure in the carbonization chamber is too high.
2) The raw gas is led out in time, so that the coke can exchange heat in the carbonization chamber, meanwhile, the heat exchange efficiency of the furnace end part is improved through the staggered groove, and the maturation condition of the coke of the furnace end can be effectively improved through the combination of the two functions.
