Example 1:
as shown in fig. 1, the present embodiment provides a heat exchange coke oven which is composed of five parts, namely, a top area 6, a heat exchange chamber 7, a chute area, a carbonization chamber and a combustion chamber, which are arranged in sequence from top to bottom, wherein in the present embodiment, the internal structures of the top area 6 and the heat exchange chamber 7 of the heat exchange coke oven are mainly explained. Specifically, the furnace ceiling region 6 includes an air passage formed by communicating through holes in a plurality of air duct bricks with each other, and a first distribution pipe 2 inserted and fixed in the air passage, the first distribution pipe 2 being for conducting air blown by an air blowing device communicating with an air passage thereof.
The coke oven with the heat exchange chamber 7 in this embodiment may include an air blowing device, or may not include an air blowing device, which is not limited herein. For the purpose of understanding the present embodiment, an air blowing device will be described as an example of a blower.
Since the first distribution pipe 2 is inserted and fixed in the air passage in the embodiment, and the first distribution pipe 2 is communicated with the air passage of the blower, in the embodiment, the air in the heat exchange coke oven is directly blown into the first distribution pipe 2 by the blower, rather than being blown into the air passage by the blower as in the prior art, thereby avoiding the occurrence of the situation that fire clay in the air passage is broken by the burst of the fire clay due to the overlarge pressure of the air blown into the air passage by the blower in the prior art, further avoiding the occurrence of the situation that the air is leaked outwards through the gap, and improving the tightness of the heat exchange coke oven.
Further preferably, in order to improve the efficiency of the first distribution pipe 2 conducting air in the present embodiment, the outer wall of the first distribution pipe 2 is completely attached to the inner wall of the air passage, and in this case, the hollow structure of the first distribution pipe 2 fixed to the air passage can have the maximum inner diameter for the inner wall of the air passage having the same diameter, and thus the amount of air contained in the hollow structure of the first distribution pipe 2 is greatly increased, that is, the amount of air flowing through is increased, thereby improving the efficiency of the first distribution pipe 2 conducting air in the present embodiment.
In the present embodiment, it is preferable that the heat exchange type coke oven in the present embodiment further includes a heat exchange chamber 7, the second distribution pipe 3 is inserted and fixed in a cavity of the heat exchange chamber 7, and the second distribution pipe 3 is in gas communication with the first distribution pipe 2. That is, the air blown by the blower is conducted from the first distribution pipe 2 to the second distribution pipe 3 to reach the heat exchange chamber 7 of the present embodiment, rather than being directly transmitted from the air passage to the cavity of the heat exchange chamber 7 as in the prior art, thereby avoiding the occurrence of the situation that the air passage and the heat exchange chamber 7 are broken by the fire clay to form a gap due to the excessive blowing pressure when the blower blows the air into the air passage and the cavity of the heat exchange chamber 7, and further improving the tightness of the heat exchange coke oven provided by the present embodiment.
Further preferably, in order to improve the air conduction efficiency of the second distribution pipe 3 in the present embodiment, the outer wall of the second distribution pipe 3 completely fits the inner wall of the chamber, and at this time, for the inner wall of the chamber with the same diameter, the arrangement is such that the hollow structure of the second distribution pipe 3 fixed in the chamber of the heat exchange chamber 7 has the largest inner diameter, so that the amount of air contained in the hollow structure of the second distribution pipe 3 is greatly increased, that is, the air circulation amount is increased, thereby improving the air conduction efficiency of the second distribution pipe 3 in the present embodiment.
Still more preferably, the bottom of the heat exchange chamber 7 facing away from the exhaust port of the first distribution pipe 2 in the present embodiment is provided with a plurality of openings, each opening is inserted with a heat exchange pipe 1, the heat exchange pipe 1 is in gas circuit communication with the second distribution pipe 3, that is, the air in the second distribution pipe 3 is transmitted through the plurality of heat exchange pipes 1 arranged at the bottom of the heat exchange chamber 7, so as to further improve the tightness of the heat exchange type coke oven provided by the present embodiment.
In the present embodiment, the material of the first distribution pipe 2 and the second distribution pipe 3 preferably includes stainless steel, and the first distribution pipe 2 and the second distribution pipe 3 made of stainless steel have high toughness, so that even if the pressure of the blower blowing air is high, the inner surface of the first distribution pipe 2 does not crack with the increase of the pressure, that is, the air blown by the blower is prevented from leaking through the gap, and the tightness of the heat exchange coke oven is improved.
In order to simplify the preparation process of the heat exchange coke oven of the present embodiment, the first distribution pipe 2 and the second distribution pipe 3 of the present embodiment may be separately prepared, and then the separately prepared first distribution pipe 2 and second distribution pipe 3 may be connected together by welding. Of course, the first distribution pipe 2 and the second distribution pipe 3 may be connected together by other connection methods, and are not limited herein.
It should be noted that, since the air duct bricks in the prior art are all refractory bricks, and the refractory bricks are very likely to expand when heated, if the first distribution pipe 2 and the second distribution pipe 3 are respectively disposed in the air passage surrounded by the refractory bricks and the chamber of the heat exchange chamber 7, the expanded refractory bricks easily drive the first distribution pipe 2 and the second distribution pipe 3 to deform, thereby reducing the service life of the first distribution pipe 2 and the second distribution pipe 3, and preferably, the air duct bricks in this embodiment include cast iron bricks 4. Of course, the air duct brick in this embodiment is not limited to the cast iron brick 4, as long as it has an expansion coefficient smaller than that of the refractory brick under a heated condition, and is not limited thereto. In addition, it should be noted that, since the cast iron bricks 4 are more expensive than the refractory bricks, in the heat exchange chamber 7 coke oven of the present embodiment, only the air duct bricks for constructing the air duct, the chamber of the heat exchange chamber 7, are replaced with the cast iron bricks 4.
In order to further improve the tightness of the coke oven of the present embodiment, the coke oven of the present embodiment further includes a connecting member 5 fixed to the first distribution pipe 2 by flange connection for connecting the first distribution pipe 2 and the blower. The connecting member 5 may be a sealing valve, and the connecting member 5 in this embodiment is not limited to the sealing valve described above, and is not limited herein.
In summary, since the first distribution pipe 2 and the second distribution pipe 3 are respectively inserted into the air passage and the chamber of the heat exchange chamber 7 in the present embodiment, and the first distribution pipe 2 is communicated with the blower gas passage, and the second distribution pipe 3 is communicated with the first distribution pipe 2, in the present embodiment, the air in the heat exchange coke oven is directly blown into the first distribution pipe 2 by the blower and then conducted to the second distribution pipe 3, instead of being blown into the air passage by the blower and then conducted to the chamber of the heat exchange chamber 7 as in the prior art, thereby avoiding the occurrence of the situation that the air passage and the fire mud in the heat exchange chamber 7 are broken by the burst of the air caused by the excessive blowing pressure when the blower blows the air into the air passage and the chamber of the heat exchange chamber 7, and further avoiding the occurrence of the situation that the air is leaked outwards through the gap, the tightness of the heat exchange type coke oven is improved.
It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
