Description

Technical Field

[0001] The present invention relates to the technical field of gas flow regulation, in particular to a gas flow bidirectional regulation device and a coke oven using the same. Background Art

[0002] During industrial production processes, the flow direction of gas in some gas pipelines will change according to production needs; the composition, physical parameters, temperature, pressure, etc. of gases with different flow directions may change, resulting in uneven gas flow rate in the pipeline. Therefore, each time the gas flow direction changes, the gas flow rate needs to be adjusted. For example, in a coke oven, the airflow direction in each coke oven regenerator will be exchanged regularly. The rising airflow is air or gas, and the descending airflow is the exhaust gas after combustion. The type and temperature of the gas in the rising and descending airflows are different, and different resistance coefficients need to be provided for the airflow to ensure uniform gas flow. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The first aspect of the present invention provides a gas flow bidirectional regulating device 1, such as Figure 1 and Figure 2 As shown, it includes a first layer of porous plate 1-1 and a second layer of porous plate 1-2;

[0027] The first layer of porous plate 1-1 includes at least one sub-porous plate;

[0028] The second layer of porous plates 1-2 includes the same number of sub-porous plates as the first layer of porous plates 1-1;

[0029] The first layer of porous plates 1-1 and the second layer of porous plates 1-2 are arranged in parallel, and the projections of the plate surface of any sub-porous plate in the first layer of porous plates 1-1 and the plate surface of the sub-porous plate in the second layer of porous plates 1-2 opposite thereto on the same plane coincide with each other;

[0030] The distance between the two layers of porous plates is 0<d≤400mm, preferably 10≤d≤100mm;

[0031] Any sub-multi-porous plate in the first layer of multi-porous plate 1-1 and the sub-multi-porous plate in the second layer of multi-porous plate 1-2 opposite thereto have at least one different opening parameter; the opening parameter includes hole position, hole shape, hole size and hole number.

[0032] The position, shape, size, and number of holes in a porous plate all affect the plate's resistance coefficient. When the positions, shapes, sizes, and / or numbers of holes on two porous plates differ, the two plates provide different resistance coefficients for gas flowing through them. Furthermore, when gas passes through the two plates from different directions, the two plates provide different total resistance coefficients for gas flowing in different directions. Those skilled in the art can design the position, shape, size, and number of holes in the corresponding sub-porous plates, as well as the distance between the two layers of porous plates, based on the required resistance coefficients for airflow in both directions. This is not detailed in the present invention.

[0033] In the specific implementation process, the “same plane” mentioned in the present invention may refer to a plane that is parallel to both the first porous plate 1 - 1 and the second porous plate 1 - 2 .

[0034] The shapes and sizes of the holes on the same porous plate can be the same or different, and the present invention does not limit this.

[0035] In some embodiments of the first aspect of the present invention, each sub-perforated plate is provided with a shielding plate, wherein the area of ​​the shielding plate is smaller than the area of ​​the corresponding sub-perforated plate, and the shielding plate is used to adjust the number of openings open on the sub-perforated plate. In some embodiments of the first aspect of the present invention, the shielding plate may be a metal plate, and the shielding plate may be placed on the sub-perforated plate to shield a portion of the openings of the sub-perforated plate, thereby adjusting the number of openings open on the sub-perforated plate.

[0036] In some embodiments of the first aspect of the present invention, the sub-porous plates are all metal porous plates, which can be machined precisely, thus facilitating precise regulation of gas flow.

[0037] In some embodiments of the first aspect of the present invention, each layer of the porous plate includes at least two sub-porous plates arranged in the same direction.

[0038] In some embodiments of the first aspect of the present invention, at least two fixed shafts 2 are further included, and the at least two fixed shafts 2 are arranged in parallel; any sub-multi-porous plate in the first layer of multi-porous plates 1-1 and the sub-multi-porous plate in the second layer of multi-porous plates 1-2 opposite thereto are fixed to the same two fixed shafts 2. For example, when a sub-multi-porous plate in the first layer of multi-porous plates 1-1 is fixed to the first fixed shaft and the second fixed shaft, a sub-multi-porous plate in the second layer of multi-porous plates 1-2 opposite thereto is also fixed to the first fixed shaft and the second fixed shaft.

[0039] In some embodiments of the first aspect of the present invention, when each layer of multi-well plates includes at least two sub-multi-well plates arranged in the same direction, the number of fixed shafts 2 is one more than the number of sub-multi-well plates in each layer of multi-well plates. For example, when each layer of multi-well plates includes four sub-multi-well plates, the number of fixed shafts may be five; in this case, adjacent sub-multi-well plates in a layer of multi-well plates share one fixed shaft.

[0040] In some embodiments of the first aspect of the present invention, rolling wheels 3 are provided at both ends of each fixed shaft 2 .

[0041] In some embodiments of the first aspect of the present invention, each sub-perforated plate is rectangular; in some embodiments of the first aspect of the present invention, the fixed axis 2 is arranged parallel to the width of the rectangular sub-perforated plate. In specific implementations, the sub-perforated plates in each layer of the perforated plate can be arranged along the length of the rectangle.

[0042] Alternatively, in some other embodiments of the first aspect of the present invention, the fixed axis 2 is arranged parallel to the length direction of the rectangular sub-perforated plates. In a specific implementation, the sub-perforated plates in each layer of the perforated plates can be arranged along the width direction of the rectangle.

[0043] In some embodiments of the first aspect of the present invention, each sub-perforated plate is detachably fixed to the fixed shaft 2. The sub-perforated plates in the perforated plate of the present invention can be arbitrarily replaced as needed to meet the needs of different production conditions.

[0044] For example, taking a rectangular sub-porous plate as an example, two slots along the axial direction of the fixed axis can be set on opposite sides of the fixed axis. The length of the slot is the same as the width of the sub-porous plate, and the distance between the two slots on the same side is the same as the distance between the two layers of porous plates. The four sub-porous plates adjacent to the fixed axis are inserted into the slots and fixed by pins; technicians in this field can also choose other fixing methods as needed. This is a commonly used technical means in this field and the present invention is not limited here.

[0045] A second aspect of the present invention provides a coke oven, such as Figure 3 and Figure 4 As shown, the top of the small flue 4 is connected to at least one regenerator compartment 5, and the gas flow bidirectional regulation device 1 provided by the first aspect of the present invention is provided at the connection between the small flue 4 and the regenerator compartment 5. In the first layer of porous plates of the gas flow bidirectional regulation device 1 close to the regenerator compartment 5, each sub-porous plate covers the entrance of one regenerator compartment 5.

[0046] In some embodiments of the second aspect of the present invention, at the connection between the small flue 4 and the heat storage chamber partition 5, the top two side walls of the small flue 4 are provided with protrusions along the long direction (machine side-coke side direction) of the small flue 4, and the gas flow bidirectional regulating device 1 is provided above the protrusions.

[0047] In some embodiments of the second aspect of the present invention, when the coke oven has at least two heat storage chamber compartments 5, a sealing baffle is provided above the connection between adjacent sub-porous plates in the first layer of porous plates, and the sealing baffle is in close contact with the bottom of the partition wall 6 of the heat storage chamber compartment 5 to isolate the space above the adjacent sub-porous plates in the first layer of porous plates.

[0048] In some embodiments of the second aspect of the present invention, the sub-porous plate is rectangular; the gas flow bidirectional regulation device 1 also includes a plurality of fixed axes 2 arranged parallel to the width direction of the rectangular sub-porous plate; any sub-porous plate in the first layer of porous plates 1-1 and the sub-porous plate in the second layer of porous plates 1-2 opposite thereto are fixed on the same two fixed axes 2, and the number of fixed axes 2 is one more than the number of sub-porous plates in each layer of porous plates, that is, two adjacent sub-porous plates in the first layer of porous plates and the two sub-porous plates in the corresponding second layer of porous plates are fixed on the same fixed axis.

[0049] In some embodiments of the second aspect of the present invention, a rolling wheel 3 is provided on the fixed shaft 2 so that the gas flow bidirectional adjustment device 1 can move along the length direction (machine side-coke side direction) of the small flue 4.

[0050] In some embodiments of the second aspect of the present invention, the sealing baffle is fixed to the fixed shaft 2 in a detachable connection manner. Exemplarily, a slot is provided on the fixed shaft, and the sealing baffle is inserted into the slot to be fixed to the fixed shaft 2.
