Description

Technical Field

[0001] This invention relates to the field of coke oven flue gas emission technology, and in particular to a dust removal device and method for a coke oven quenching car. Background Technology

[0002] In coke oven production, the coke quenching car is a coke guiding device that delivers coke into the coke pot through a designated path via a coke guide grid. (Refer to...) Figure 1 When the coke quenching car 100' moves to the coke oven door 2001', the first dust removal pipe 1' is sealed to the dust collection pipe 300'. The coke pusher 2002' pushes the coke 400' inside the coke oven 200' so that the coke 400' passes through the coke guide grid 3' and falls into the coke pot 600'. While the coke quenching car 100' is performing coke guiding operations, a large amount of dust 500' will be generated. The second dust removal pipe 2' is used to absorb the dust 500' located near the coke oven door 2001' of the coke quenching car 100' into the dust removal hood 4'. The first dust removal pipe 1' absorbs the dust 500' in the dust removal hood 4' into the dust collection pipe 300'.

[0003] The existing technology has the following problems: the second dust removal pipe 2' inside the coke quenching car 100' is fixedly installed, and it is a long distance away from the coke oven door 2001'. The suction is insufficient and cannot absorb the dust 500' located near the coke oven door 2001' in the coke quenching car 100' into the dust removal hood 4', so the dust 500' flows out through the gap between the coke quenching car 100' and the coke oven 200'. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal device and method for a coke oven, which can absorb dust between the coke oven and the coke oven and has a good dust removal effect.

[0014] As a preferred embodiment of the dust removal device for the coke quenching car, the dust removal device for the coke quenching car further includes a first driving member, which is connected to the second part in a transmission manner. The first driving member drives the second part to move along the length direction of the first part and is disposed in the cavity. The first driving member is any one of a cylinder, a motor or a hydraulic actuator.

[0015] As a preferred embodiment of the dust removal device for the coke oven car, the coke pot, the coke guide grid, and the coke oven door are located on the same straight line.

[0016] A dust removal method is provided, comprising the following steps:

[0046] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] like Figure 3 and Figure 4As shown, the present invention provides a dust removal device for a coke quenching car, including a dust removal component 1 and a coke guide grid 3. The dust removal component 1 includes a dust removal hood 101, a first dust removal pipe 102, and a second dust removal pipe 103. The dust removal hood 101 is located on the side of the coke quenching car 100 away from the coke oven 200, and covers the coke can 600 on one side of the coke quenching car 100. The dust 500 generated during the process of coke 400 falling into the coke can 600 is all contained within the dust removal hood 101, preventing the dust 500 from scattering. The side of the dust removal hood 101 closest to the coke quenching car 100 has an opening, so that the dust removal hood 101 communicates with the interior of the coke quenching car 100. The first dust removal pipe 102 communicates with the dust removal hood 101 and the dust collection pipe 300, and can absorb the dust 500 in the dust removal hood 101 into the dust collection pipe 300 through the first dust removal pipe 102. The dust collection pipe 300 is connected to the first dust removal pipe 102. Because the dust collection pipe 300 is under negative pressure, the dust 500 inside the dust collector hood 101 can be directly absorbed into the dust collection pipe 300 through the negative pressure of the first dust collector pipe 102. The second dust collector pipe 103 is installed inside the coke oven 100. The end of the second dust collector pipe 103 away from the coke oven 200 extends into the dust collector hood 101. The second dust collector pipe 103 is a telescopic pipe, extending the second dust collector pipe 103 to the coke oven 100 and the coke oven door 2. At position 001, the second dust removal pipe 103 can absorb the dust 500 from the coke oven car 100 and the coke oven door 2001 into the dust removal hood 101, and then absorb it into the dust collection pipe 300 through the first dust removal pipe 102. A smoke baffle 2 is provided at one end of the second dust removal pipe 103 near the coke oven door 2001 of the coke oven 200, which can limit the dust 500 between the coke oven car 100 and the coke oven 200 and prevent the dust 500 from scattering. The coke guide grid 3 is installed in the coke quenching car 100, moving towards or away from the coke oven 200. The coke guide grid 3 has a hollow cavity that runs through both ends of the coke guide grid 3, near the coke pot 600 and the coke oven 200. The hollow cavity is connected to the dust removal hood 101. The coke pusher 2002 of the coke oven 200 pushes the coke 400 to move in the hollow cavity and pushes the coke 400 into the coke pot 600 through the opening. The coke pusher 2002 can directly push the coke 400 into the hollow cavity of the coke guide grid 3 and allow the coke 400 to fall directly into the coke pot 600 through the opening on the dust removal hood 101. The dust 500 generated during the coke pushing process can be directly absorbed into the dust collection pipe 300 through the first dust removal pipe 102. By setting up a dust removal component 1, the first dust removal pipe 102 is connected to the dust removal hood 101 and the dust collection pipe 300 respectively. The first dust removal pipe 102 can absorb the dust in the dust removal hood 101 into the dust collection pipe 300. The second dust removal pipe 103, which can be extended and retracted, absorbs the dust 500 located at the coke oven car 100 and the coke oven door 2001 into the dust removal hood 101. By setting a baffle plate 2 on the second dust removal pipe 103, the upward flow of dust 500 is restricted, resulting in a good dust removal effect.

[0050] Preferably, the coke pot 600, the coke guide grid 3, and the coke oven door 2001 are located on the same straight line. During the coke pushing process, the coke pushing rod 2002 can directly push the coke 400 from the coke oven door 2001 into the hollow cavity of the coke guide grid 3, and push the coke 400 directly into the coke pot 600 through the opening on the dust removal hood 101 through the hollow cavity. As the coke pushing rod 2002 moves along the direction close to the coke blocking car 100, it can directly push the coke 400 into the coke pot 600, which is convenient to operate.

[0051] Preferably, the size of the dust hood 101 gradually increases along the direction close to the coke pot 600, and the size of the dust hood 101 on the side close to the coke pot 600 is larger than the size of the coke pot 600, so that the dust hood 101 can directly cover the coke pot 600. The setting that the size of the dust hood 101 is larger than the size of the coke pot 600 can effectively confine the dust 500 generated during the coke pushing process within the dust hood 101 to prevent the dust 500 from scattering.

[0052] Reference Figure 5 The second dust removal pipe 103 includes a first part 1031 and a second part 1032. The end of the first part 1031 away from the coke oven 200 extends into the dust removal hood 101. A cavity is provided in the first part 1031, and the cavity extends through both ends of the first part 1031 along its length. The second part 1032 is movable and disposed in the cavity along the length of the first part 1031. The second part 1032 can move in the direction close to the coke oven 200, so that the end of the second part 1032 away from the first part 1031 moves to the coke oven door 2001 and can directly absorb the dust 500 between the coke quenching car 100 and the coke oven door 2001. A smoke baffle 2 is provided at the end of the second part 1032 away from the first part 1031. The smoke baffle 2 can directly restrict the dust 500 at the coke oven 200 and the coke quenching car 100 to prevent the dust 500 from scattering.

[0053] Specifically, the second part 1032 includes two side plates spaced vertically apart. The side plate at the top is the first side plate. The smoke baffle 2 is disposed on the first side plate and at the top of the second part 1032. The smoke baffle 2 can directly restrict the upward flow of dust 500 and block the dust 500 at the end of the second part 1032 away from the first part 1031. The second part 1032 can directly absorb the dust 500 located between the coke quenching car 100 and the coke oven 200, so that the dust 500 is absorbed into the dust hood 101 through the second part 1032 and the first part 1031 in sequence, and then absorbed into the dust collection pipe 300 through the first dust collection pipe 102. The length of the smoke baffle 2 extends in a direction perpendicular to the first side plate, increasing the area of ​​the smoke baffle 2 that restricts the flow of dust 500, so that the dust 500 can be largely restricted by the smoke baffle 2 on the side of the second part 1032 away from the first part 1031.

[0054] In one embodiment, the length of the smoke baffle 2 is greater than or equal to the length of the coke oven door 2001. The smoke baffle 2 is positioned above the coke oven door 2001 and covers the top of the coke oven door 2001, so that the smoke baffle 2 can restrict the dust 500 flowing out of the coke oven door 2001 to the smoke baffle 2, effectively restricting the coke oven door 2001 to the bottom of the smoke baffle 2.

[0055] In other embodiments, refer to Figure 6 The smoke baffle 2 includes a first plate 201 and two second plates 202. The first plate 201 is disposed on the first side plate and extends along a direction perpendicular to the first side plate. The two second plates 202 are disposed at both ends of the first plate 201 along its length. The first plate 201 and the two second plates 202 form an area that restricts the flow of dust 200, thus confining the dust 500 flowing out of the coke oven door 2001 within the area enclosed by the first plate 201 and the two second plates 202. The dust 500 is then absorbed into the dust hood 101 through the second dust removal pipe 103.

[0056] Specifically, the coke oven 200 is provided with a side wall of coke oven door 2001 as the first side wall. The length of the first plate 201 is greater than or equal to the length of the coke oven door 2001. The first plate 201 is located above the coke oven door 2001 and covers the top of the coke oven door 2001. The first plate 201 and the second plate 202 both abut against the first side wall, so that the first plate 201, the second plate 202 and the first side wall form a dust removal space, and the dust 500 is absorbed into the dust removal hood 101 through the second dust removal pipe 103.

[0057] In one embodiment, the dust removal device for the coke quenching car further includes a first driving member 4, which is connected to the second part 1032 in a transmission manner. The first driving member 4 drives the second part 1032 to move along the length direction of the first part 1031 and is disposed in the cavity. The first driving member 4 drives the second part 1032 to move to the coke oven door 2001 so that the second part 1032 can absorb the dust 500 between the coke quenching car 100 and the coke oven 200. The first driving member 4 is any one of a cylinder, a motor or a hydraulic actuator.

[0058] like Figure 3 and Figure 4 As shown, the first dust removal pipe 102 is a retractable pipe. During the dust removal process of the coke quenching car 100, the first dust removal pipe 102 can be directly extended to the dust collection pipe 300 so that the first dust removal pipe 102 can be directly connected to the dust collection pipe 300 and perform dust suction treatment on the dust 500 in the dust removal hood 101. After the coke quenching car 100 pushes the coke, the first dust removal pipe 102 can be directly removed from the dust collection pipe 300. The first dust removal pipe 102 will retract to its initial position, effectively reducing the volume of the first dust removal pipe 102.

[0059] Preferably, at least two first dust removal pipes 102 are provided, and all the first dust removal pipes 102 are spaced apart on the same side of the dust removal hood 101 away from the coke quenching car 100, so that multiple first dust removal pipes 102 can simultaneously absorb the dust 500 in the dust removal hood 101, thereby improving the efficiency of the first dust removal pipes 102 in absorbing the dust 500 and making the dust removal effect better.

[0060] In this embodiment, the dust removal device of the coke oven car also includes a door removal component, which is connected to the coke oven door 2001 of the coke oven 200 in a transmission manner. The door removal component is used to open or close the coke oven door 2001.

[0061] The present invention also provides a dust removal method, comprising the following steps:

[0062] Step S1: The coke quenching car 100 is moved to the coke oven door 2001, and the first dust removal pipe 102 is inserted into the dust collection pipe 300;

[0063] Step S2: The coke guide grid 3 is moved to a position close to the coke oven door 2001, and the second dust removal pipe 103 is extended to the coke oven door 2001;

[0064] Step S3: The coke pusher 2002 pushes the coke 400, and the coke 400 falls into the coke pot 600 in sequence through the hollow cavity and the opening;

[0065] Step S4: The coke pusher 2002 moves out of the coke guide grid 3 in the direction close to the coke oven 200, and the second dust removal pipe 103 extends and retracts into the coke quenching car 100;

[0066] Step S5: The coke guide grid 3 moves away from the coke oven door 2001 and pulls the first dust removal pipe 102 out of the dust collection pipe 300.

[0067] The dust removal method provided by this invention involves the following steps: after the coke quenching car 100 moves to the coke oven door 2001, the first dust removal pipe 102 is inserted into the dust collection pipe 300, and the second dust removal pipe 103 extends to the coke oven door 2001. The coke pusher 2002 pushes the coke 400, causing it to pass through the coke oven door 2001 and then sequentially through the hollow cavity and opening into the coke can 600. The second dust removal pipe 103 can absorb the dust 500 at the coke quenching car 100 and the coke oven door 2001, and collect the dust 500 into the dust removal hood 101. The dust 500 is then collected into the dust collection pipe 300 through the first dust removal pipe 102, resulting in a good dust removal effect.

[0068] In step S1, after the coke quenching car 100 moves to the designated coke oven door 2001, the door-removing component moves to the coke oven door 2001 and opens it. In step S3, the coke pusher 2002 pushes the coke 400 through the coke oven door 2001 into the hollow cavity. In step S5, after the coke pushing is completed, the coke guide grid 3 moves away from the coke oven door 2001, and then the door-removing component closes the coke oven door 2001.

[0069] In step S2, when the second dust removal pipe 103 extends to the coke oven door 2001, the smoke baffle 2 is positioned above the coke oven door 2001 to restrict the upward flow of dust 500, so that the second part 1032 can absorb the dust 500 located between the coke quenching car 100 and the coke oven 200.

[0070] After the coke pushing is completed, the coke quenching car 100 can be moved to the next coke oven door 2001 and the above steps can be repeated.
