After a large number of experiments and researches, the inventor of the invention finds that the specific reasons of the phenomena of bulging, brick falling, collapse and the like of the dry quenching furnace are as follows: in the process that the gas for cooling coke enters the annular air duct and is led out through the annular air duct, the gas flow velocity difference values at different positions are too large, so that the air pressure in the annular air duct is uneven, the local stress of the inner surrounding wall 20 is too high, and finally the problems of deformation, brick falling, collapse and the like of the inner surrounding wall 20 are caused.
In order to solve the above technical problems, the present invention provides a dry quenching furnace, as shown in fig. 2 to 7, the dry quenching furnace comprises a pre-storage section D1, a transition section D2 and a cooling section D3, which are sequentially arranged along a height direction, cavities of the pre-storage section D1, the transition section D2 and the cooling section D3 are communicated, the transition section D2 comprises an outer surrounding wall 10 and an inner surrounding wall 20, the inner surrounding wall 20 is arranged around the cavity of the transition section D2, the outer surrounding wall 10 is arranged around the inner surrounding wall 20, an annular air duct 30 is formed between the inner surrounding wall 20 and the outer surrounding wall 10, the annular air duct 30 is communicated with the cooling section D3, a first supporting wall 31 and a plurality of vertical partition walls 33 are arranged in the annular air duct, an air outlet 34 is arranged on the outer surrounding wall 10, one side of the first supporting wall 31 is connected with the inner surrounding wall 20, the other side of the first supporting wall 31 is connected with the outer surrounding wall 10, and the annular air duct is divided into a first air duct and a second air duct which are isolated from each other by the first supporting wall 31 and the air outlet 34.
One side of vertical partition wall 33 links to each other with interior surrounding wall 20, and the opposite side of vertical partition wall 33 links to each other with outer surrounding wall 10, be provided with at least one vertical partition wall 33 in the first wind channel, in order to incite somebody to action first wind channel is separated into a plurality of first sub-wind channels, be provided with at least one vertical partition wall 33 in the second wind channel, in order to incite somebody to action the second wind channel is separated into a plurality of second sub-wind channels, first sub-wind channel with the second sub-wind channel all can be with the cavity intercommunication of annular wind channel 30 and cooling zone D2.
It should be noted that, when the air at each position enters the annular air duct 30 of the transition section D2 from the cooling section D3, the air firstly enters the sub-air ducts between the vertical partition walls 33, then joins through the air permeable gaps reserved above the vertical partition walls 33, flows along the arrangement direction of the annular air duct 30, and is discharged out of the annular air duct 30.
In the invention, a plurality of vertical partition walls 33 are further arranged between the inner surrounding wall 20 and the outer surrounding wall 10, so that the space communicated with the cavity of the annular air duct 30 and the cooling section D3 can be divided into a plurality of sub-air ducts, and when air at each position enters the annular air duct 30 of the transition section D2 from the cooling section D3, the air speed of hot air flowing through each sub-air duct is kept constant, thereby reducing the air speed difference between different positions in the whole annular air duct 30, enabling the stress distribution on the inner surrounding wall 20 to be more uniform, and avoiding the problems of bulging, brick falling, collapse and the like.
It should be noted that, in the present invention, the first supporting wall 31 and the air outlet 34 divide the annular air duct into a first air duct and a second air duct that are isolated from each other, which means that the first supporting wall 31 completely and radially partitions the annular air duct 30, so that when air enters the annular air duct 30 of the transition section D2 from the cooling section D3, the air entering the sub-air ducts at two sides of the first supporting wall 31 respectively flows to the air outlet 34 at two sides of the first supporting wall 31, and the air is guided out to the air treatment equipment by the air outlet 34 for processes such as heat recovery.
In order to make the stress distribution on the outer and inner surrounding walls 10 and 20 more uniform, it is preferable that the first supporting wall 31 be disposed opposite to the outlet port 34 as shown in fig. 5 to 7.
In fig. 2 to 7, 0 ° represents a direction in which the first support wall 31 is located, and 180 ° represents a direction in which the outlet 34 is located. The first supporting wall 31 is disposed opposite to the air outlet 34, so that the lengths of the first air duct and the second air duct are substantially the same, the air pressure difference between the two air ducts is balanced, and the stress distribution on the outer surrounding wall 10 and the inner surrounding wall 20 is more uniform.
In order to enhance the strength of the inner surrounding wall 20, it is preferable that, as shown in fig. 2, a second supporting wall 32 is further disposed in the annular duct 30, the second supporting wall 32 is disposed corresponding to the air outlet 34, and the second supporting wall 32 is connected to the inner surrounding wall 20. In the present invention, the first and second support walls 31 and 32, which are oppositely disposed, support the inner surrounding wall 20 from opposite sides, respectively, thereby improving the strength of the inner surrounding wall 20 and preventing the inner surrounding wall 20 from being deformed.
The shape of the second support wall 32 is not particularly limited in the present invention, and for example, as shown in fig. 2, the width of the second support wall 32 is optionally gradually increased in a direction from the preliminary stage D1 to the cooling stage D3.
The extending direction of the vertical partition wall 33 is not particularly limited in the present invention, for example, the vertical partition wall 33 may alternatively extend in the radial direction of the cavity of the transition section D2.
In order to further balance the stress at each position on the outer surrounding wall 10 and the inner surrounding wall 20, it is preferable that, among the plurality of vertical partition walls 33, the vertical partition wall 33 circumferentially distant from the wind outlet 34 has a height higher than that of the vertical partition wall 33 circumferentially distant from the wind outlet 34, as shown in fig. 3 to 7.
As shown in fig. 5, after entering the annular air duct 30, the hot air flows through the sub-air ducts separated by the vertical partition walls 33, and then flows towards the air outlet 34 located at 0 ° around the cavity of the dry quenching furnace in the horizontal direction. In the present invention, the height of the vertical partition wall 33 circumferentially distant from the air outlet 34 is set higher than the height of the vertical partition wall 33 circumferentially distant from the air outlet 34, so that not only can the uniformity of the wind speeds in the sub-air ducts partitioned by the respective vertical partition walls 33 be maintained, but also the wind speeds (V1 to V7) of the hot air horizontally flowing from the outlets of the respective sub-air ducts to the air outlet 34 can be more uniformly distributed in the vertical direction, thereby further improving the uniformity of the air flow in the vertical partition wall 33, and balancing the stress at each position on the outer surrounding wall 10 and the inner surrounding wall 20.
In order to ensure the supporting capability of the first supporting wall 31 without affecting the air outlet function of the air outlet 34, it is preferable that the width of the first supporting wall 31 gradually increases from a portion toward the pre-storage section D1 to a portion toward the cooling section D3.
In order to increase the stability of the structure of the dry quenching furnace body and improve the uniformity of the distribution of hot gas in the annular air duct 30, preferably, one side of the second support wall 32 facing the inner cavity of the dry quenching furnace is connected with the inner surrounding wall 20, and one side of the second support wall 32 facing away from the inner cavity of the dry quenching furnace is connected with the outer surrounding wall 10, so that the annular air duct 30 is divided into two parts. In the invention, the second supporting wall 32 is arranged to directly close the section of the annular air duct 30 in the 180 ° direction, and divide the annular air duct 30 into two parts, so that the hot air flowing out of each sub-air duct between the vertical partition walls 33 respectively flows to the air outlet 34 through two paths, namely the first air duct (180 ° → 90 ° → 0 °) and the second air duct (180 ° → 270 ° → 0 °), thereby improving the uniformity of the distribution of the hot air in the annular air duct 30.
In order to further balance the stress at various positions on the outer surrounding wall 10 and the inner surrounding wall 20, it is preferable that, as shown in fig. 4, 6 and 7, the dry quenching furnace further comprises a horizontal partition wall 35, one side of the horizontal partition wall 35 is connected to the inner surrounding wall 20, the other side of the horizontal partition wall 35 is connected to the outer surrounding wall 10, one end of the horizontal partition wall 35 is connected to one end of one vertical partition wall 33 facing the pre-storage section D1, and the other end of the horizontal partition wall 35 extends in the direction of the air outlet 34.
In the present invention, the inventor considers that the hot air (V1 to V4 in fig. 6 or V1 to V6 in fig. 7) flowing through the sub-ducts separated by the vertical partition 33 away from the air outlet 34 has too long flow path, which easily causes uneven distribution of air speed at each height, or causes the hot air flow (V1 to V4 in fig. 6 or V1 to V6 in fig. 7) distributed at a high position to be impacted by the hot air flow (V1 'to V3' in fig. 6 or V1 'to V6' in fig. 7) distributed at a low position, which cannot ensure smooth flow of the hot air flow distributed at a high position to the air outlet 34, so that the hot air flow distributed at a high position is retained between the outer surrounding wall 10 and the inner surrounding wall 20, which causes the outer surrounding wall 10 and the inner surrounding wall 20 to be damaged due to local over-high stress. Therefore, the horizontal partition wall 35 is additionally arranged in the invention, so that the hot air flow flowing out of the sub-air channels separated by the vertical partition wall 33 far away from the air outlet 34 is ensured to be smoothly discharged, the stress of each position on the outer surrounding wall 10 and the inner surrounding wall 20 is further balanced, and the service life of the furnace body is prolonged.
The number and the arrangement position of the horizontal partition walls 35 are not particularly limited in the present invention, and for example, it is preferable that when one horizontal partition wall 35 is respectively arranged in two air passages of the first air passage (180 ° → 90 ° → 0 °) and the second air passage (180 ° → 270 ° → 0 °), the two horizontal partition walls 35 are respectively flush with and meet the top end heights of the vertical partition walls 33 in the 90 ° direction and the vertical partition walls 33 in the 270 ° direction.
The structure of the cooling section D3 of the dry quenching furnace is not particularly limited, for example, as shown in FIGS. 2 and 4 to 7, optionally, the cooling section D3 comprises a cooling section furnace wall 40 and a uniform flow wall 50 arranged at the top end of the cooling section furnace wall 40, the uniform flow wall 50 is arranged around the top end of the cooling section furnace wall 40, one end of the uniform flow wall 50 is connected with the outer surrounding wall 10, the other end of the uniform flow wall 50 is connected with the inner surrounding wall 20 to connect the transition section D2 with the top end of the cooling section furnace wall 40, a plurality of air outlet holes 51 are arranged on the uniform flow wall 50, and the air outlet holes 51 communicate the space between the vertical partition walls 33 in the annular air duct 30 with the cavity of the cooling section D3.
The number of the vertical partition walls 33 is not particularly limited in the present invention, for example, in order to ensure the control of the flow rate of the air flowing out from each air outlet hole 51, it is preferable that, in the annular air duct 30, each of the first sub-air ducts corresponds to one air outlet hole 51, and each of the second sub-air ducts corresponds to one air outlet hole 51.
It should be noted that, in the present invention, the distance between the vertical partition walls 33 and the height of each vertical partition wall 33 can be adjusted according to the flow rate of the air flow in the actual production. For example, in order to ensure uniformity of gas flow velocity between the vertical walls 33, it is preferable that the height difference of the vertical walls 33 on both sides of the outlet hole 51, from which the outlet air velocity is higher than that of the adjacent outlet holes 51, is greater than the height difference of the vertical walls 33 on both sides of the adjacent outlet hole 51.
The arrangement mode of the uniform flow wall 50 is not particularly limited, for example, an included angle of less than 90 degrees is optionally formed between the uniform flow wall 50 and the axis of the dry quenching furnace.
The material of the wall of the dry quenching furnace is not particularly limited in the present invention, and for example, to ensure the adaptability of the furnace body to the dry quenching process, it is preferable that the wall of the dry quenching furnace is formed by stacking refractory bricks.
