[0033] The present application embodiment provides a combustion device, see Figures 1 to 6 As shown, the combustion device includes: a burner 1, a first pipeline assembly 2 and a second pipeline assembly 3, the burner 1 has a flow channel; the first pipeline assembly 2 includes: a first pipeline 21 and a first valve 22, the outlet of the first pipeline 21 is connected to the inlet of the flow channel, and the first valve 22 is arranged on the first pipeline 21; the second pipeline assembly 3 includes: a second pipeline 31 and a second valve 32, the outlet of the second pipeline 31 is connected to the outer side wall of the flow channel on the first pipeline 21 corresponding to the first valve 22 close to the flow channel, or the inlet of the flow channel, or the outer side wall of the corresponding flow channel on the burner 1, and is communicated with the corresponding first pipeline 21 or the flow channel, and the second valve 32 is arranged on the second pipeline 31.
[0034] Specifically, the burner 1 has a flow channel, and the flow channel has an inlet and an outlet, so that gas or liquid can enter through the inlet of the flow channel, flow in the flow channel, and then flow out from the outlet of the flow channel. For the convenience of description, the following description takes gas as an example.
[0035] The first pipeline assembly 2 mentioned above includes: a first pipeline 21 and a first valve 22. The outlet of the first pipeline 21 is connected to the inlet of the flow channel. The first valve 22 is arranged on the first pipeline 21. In this way, after the gas enters the first pipeline 21 from the inlet of the first pipeline 21, it flows into the flow channel from the outlet of the first pipeline 21 and finally flows out from the outlet of the flow channel. The first valve 22 arranged on the first pipeline 21 can control the flow state of the gas in the first pipeline 21. For example, the first valve 22 controls the gas in the first pipeline 21 to stop flowing. For another example, the first valve 22 controls the gas in the first pipeline 21 to flow. For another example, the first valve 22 controls the unit flow of the gas in the first pipeline 21 to increase or decrease.
[0036] The second pipeline assembly 3 mentioned above includes: a second pipeline 31 and a second valve 32. The outlet of the second pipeline 31 is connected to the outer wall of the flow channel corresponding to the first valve 22 on the first pipeline 21, or the inlet of the flow channel, or the outer wall of the flow channel corresponding to the burner 1, and is connected to the corresponding first pipeline 21 or the flow channel. The second valve 32 is arranged on the second pipeline 31. In this way, after the gas enters the second pipeline 31 from the inlet of the second pipeline 31, it flows into the first pipeline 21 or the flow channel from the outlet of the second pipeline 31, and finally flows out from the outlet of the flow channel. The second valve 32 arranged on the second pipeline 31 can control the flow state of the gas in the second pipeline 31, for example: the second valve 32 controls the gas in the second pipeline 31 to not flow, and for example: the second valve 32 controls the gas in the second pipeline 31 to flow; for example: the second valve 32 controls the unit flow of the gas in the second pipeline 31 to increase or decrease. Here, the structure of the second valve 32 may be consistent with the structure of the first valve 22, or it may be inconsistent.
[0037] In some specific embodiments, see Figure 1 As shown, the combustion device includes: a burner 1, a first pipeline assembly 2 and a second pipeline assembly 3, the burner 1 has a flow channel; the first pipeline assembly 2 includes: a first pipeline 21 and a first valve 22, the outlet of the first pipeline 21 is connected to the inlet of the flow channel, and the first valve 22 is arranged on the first pipeline 21; the second pipeline assembly 3 includes: a second pipeline 31 and a second valve 32, the outlet of the second pipeline 31 is connected to the outer side wall of the first pipeline 21 corresponding to the first valve 22 close to the flow channel, and is communicated with the corresponding first pipeline 21, and the second valve 32 is arranged on the second pipeline 31. Among them, the first pipeline 21 is used to transport combustion-supporting gas (such as uncompressed oxygen) to the flow channel of the burner 1 so that the flow channel outlet of the burner 1 can burn, and the second pipeline 31 is used to input high-pressure gas (such as compressed oxygen, compressed nitrogen) for cleaning the flow channel into the flow channel of the burner 1 through the first pipeline 21. The high-pressure gas can impact the coking materials in the flow channel and at the flow channel outlet to clean the coking of the burner 1, and the first valve 22 and the second valve 32 can control whether the first pipeline 21 provides combustion-supporting gas into the flow channel or the second pipeline 31 provides high-pressure gas for cleaning the flow channel into the flow channel.
[0038] In some other specific embodiments, see Figure 2As shown, the combustion device includes: a burner 1, a first pipeline assembly 2 and a second pipeline assembly 3, the burner 1 has a flow channel; the first pipeline assembly 2 includes: a first pipeline 21 and a first valve 22, the outlet of the first pipeline 21 is connected to the inlet of the flow channel, and the first valve 22 is arranged on the first pipeline 21; the second pipeline assembly 3 includes: a second pipeline 31 and a second valve 32, the outlet of the second pipeline 31 is connected to the inlet of the flow channel and communicates with the flow channel, and the second valve 32 is arranged on the second pipeline 31. Among them, the first pipeline 21 is used to transport combustion-supporting gas (such as uncompressed oxygen) to the flow channel of the burner 1 so that the flow channel outlet of the burner 1 can burn, and the second pipeline 31 is used to input high-pressure gas (such as compressed oxygen, compressed nitrogen) for cleaning the flow channel into the flow channel of the burner 1. The high-pressure gas can impact the coking materials in the flow channel and at the flow channel outlet to clean the coking of the burner 1, and the first valve 22 and the second valve 32 can control whether the first pipeline 21 provides combustion-supporting gas into the flow channel or the second pipeline 31 provides high-pressure gas for cleaning the flow channel into the flow channel.
[0039] In some other embodiments, see Figure 3 and Figure 4 As shown, the combustion device includes: a burner 1, a first pipeline assembly 2 and a second pipeline assembly 3, the burner 1 has a flow channel; the first pipeline assembly 2 includes: a first pipeline 21 and a first valve 22, the outlet of the first pipeline 21 is connected to the inlet of the flow channel, and the first valve 22 is arranged on the first pipeline 21; the second pipeline assembly 3 includes: a second pipeline 31 and a second valve 32, the outlet of the second pipeline 31 is connected to the outer side wall of the corresponding flow channel on the burner 1 and communicates with the flow channel, and the second valve 32 is arranged on the second pipeline 31. Among them, the first pipeline 21 is used to transport combustion-supporting gas (such as uncompressed oxygen) to the flow channel of the burner 1 so that the flow channel outlet of the burner 1 can burn, and the second pipeline 31 is used to input high-pressure gas (such as compressed oxygen, compressed nitrogen) for cleaning the flow channel into the flow channel of the burner 1. The high-pressure gas can impact the coking materials in the flow channel and at the flow channel outlet to clean the coking of the burner 1, and the first valve 22 and the second valve 32 can control whether the first pipeline 21 provides combustion-supporting gas into the flow channel or the second pipeline 31 provides high-pressure gas for cleaning the flow channel into the flow channel.
[0040] In this embodiment, the combustion device includes: a burner 1, a first pipeline assembly 2 and a second pipeline assembly 3. The first pipeline 21 of the first pipeline assembly 2 is used to transport combustion-supporting gas to the flow channel of the burner 1 so that the flow channel outlet of the burner 1 can burn. The second pipeline 31 of the second pipeline assembly 3 is used to input high-pressure gas for cleaning the flow channel through the first pipeline 21 or directly into the flow channel of the burner 1. The high-pressure gas can impact the coking materials in the flow channel and at the flow channel outlet to clean the coking of the burner 1. The first valve 22 and the second valve 32 can control whether the first pipeline 21 provides combustion-supporting gas into the flow channel or the second pipeline 31 provides high-pressure gas for cleaning the flow channel into the flow channel. In this way, when the coke on the burner 1 is cleaned regularly, the first valve 22 is used to control the first pipeline 21 to stop supplying the combustion-supporting gas into the flow channel of the burner 1, and the second valve 32 is used to control the second pipeline 31 to open and supply the high-pressure gas for cleaning the flow channel into the flow channel of the burner 1. The entire decoking process is completed by the combustion device to ensure the stability of the cleaning process; and one person only needs to control the first valve 22 and the second valve 32 to reduce labor costs. At the same time, since there is no need to disassemble, clean, and install the burner 1, the operation time can be shortened.
[0041] During the specific implementation of this embodiment, when the gas provided by the second pipeline 31 is compressed oxygen and the coking cleaning is completed, the second pipeline 31 is controlled by the second valve 32 to stop supplying the high-pressure gas for cleaning the flow channel into the flow channel of the burner 1, and the first valve 22 is opened to supply the combustion-supporting gas into the flow channel of the burner 1 to resume combustion. At this time, the residual compressed oxygen provided by the second pipeline 31 will participate in the combustion so as to reduce the impurity gas in the combustion space. For this reason, it is preferred that the gas provided by the second pipeline 31 is compressed oxygen.
[0042] In some embodiments, the pressure of the gas flowing in the second pipeline 31 is greater than the pressure of the gas flowing in the first pipeline 21. Thus, compared with the speed at which the first pipeline 21 delivers the combustion-supporting gas into the flow channel, the pressure speed at which the second pipeline 31 delivers the cleaning gas into the flow channel is greater, so that the coking can be impacted quickly, thereby achieving the purpose of cleaning the coking.
[0043] In some embodiments, see Figures 1 to 4 As shown, the combustion device also includes: a third pipeline assembly 4, the third pipeline assembly 4 includes: a third pipeline 41 and a third valve 42, the outlet of the third pipeline 41 is connected to the inlet of the flow channel, and the third valve 42 is arranged on the third pipeline 41; wherein, the gas flowing in the third pipeline 41 is different from the gas flowing in the first pipeline 21.
[0044] Specifically, the outlet of the third pipeline 41 is connected to the inlet of the flow channel, and the third valve 42 is arranged on the third pipeline 41. In this way, after the gas enters the third pipeline 41 from the inlet of the third pipeline 41, it flows into the flow channel from the outlet of the third pipeline 41, and finally flows out from the outlet of the flow channel. The third valve 42 arranged on the third pipeline 41 can control the flow state of the gas in the third pipeline 41, for example: the third valve 42 controls the gas in the third pipeline 41 not to flow, and for example: the third valve 42 controls the gas in the third pipeline 41 to flow; for another example: the third valve 42 controls the unit flow of the gas in the third pipeline 41 to increase or decrease. The third pipeline 41 mentioned above is used to transport combustion-supporting gas to the flow channel, and the gas flowing in the third pipeline 41 is different from the gas flowing in the first pipeline 21. For example, the gas flowing in the first pipeline 21 is uncompressed oxygen, while the gas flowing in the third pipeline 41 is natural gas. In this way, oxygen and natural gas are mixed to burn at the outlet position of the burner 1. At the same time, the supply amount of oxygen and natural gas can be controlled by the first valve 22 and the third valve 42.
[0045] In some embodiments, see Figure 5 and Figure 6 As shown, the second pipeline assembly 3 further includes: an electromagnetic pulse valve 33 and a first controller 34 ; the electromagnetic pulse valve 33 is arranged in the second pipeline 31 ; and the first controller 34 is electrically connected to the electromagnetic pulse valve 33 .
[0046] Specifically, the electromagnetic pulse valve 33 mentioned above refers to a diaphragm valve that is controlled by an electromagnetic or pneumatic pilot valve and can instantly open and close a high-pressure gas source (such as: the high-pressure gas source 38 below) to generate pulses, and the electromagnetic pulse valve 33 is arranged in the second pipeline 31, so that the electromagnetic pulse valve 33 can control the start and close of the high-pressure gas source connected to the second pipeline 31. The first controller 34 mentioned above is electrically connected to the electromagnetic pulse valve 33, so that the first controller 34 can set the pulse frequency of the electromagnetic pulse valve 33 according to the coking situation that needs to be cleaned at present, for example: when the coking is serious, the first controller 34 controls the pulse frequency of the electromagnetic pulse valve 33 to increase.
[0047] In some embodiments, see Figure 5 and Figure 6 As shown, the second pipeline assembly 3 further includes: an electric pressure regulating valve 35 and a second controller 36 ; the electric pressure regulating valve 35 is arranged in the second pipeline 31 ; and the second controller 36 is electrically connected to the electric pressure regulating valve 35 .
[0048] Specifically, the electric pressure regulating valve 35 is arranged on the second pipeline 31, so that the electric pressure regulating valve 35 can control the pressure of the high-pressure gas in the second pipeline 31. The second controller 36 is electrically connected to the electric pressure regulating valve 35, so that the second controller 36 can set the pressure of the second controller 36 according to the coking situation that needs to be cleaned. For example, when the coking is serious, the second controller 36 controls the pressure of the electric pressure regulating valve 35 to increase.
[0049] In some embodiments, see Figure 6 As shown, the first controller 34 and the second controller 36 are the same controller. In this way, the number of controllers can be reduced, so as to simplify the structure of the combustion device and reduce the manufacturing cost of the combustion device.
[0050] In some embodiments, the combustion device further includes: a timer and a memory, wherein the timer is electrically connected to the first controller 34 ; and the memory is electrically connected to the first controller 34 .
[0051] Specifically, the timer mentioned above is electrically connected to the first controller 34, so that the cleaning personnel can predict the required cleaning time according to the severity of the coking, and count the time through the timer. When the time counted by the timer is equal to the cleaning time predicted by the cleaning personnel, the first controller 34 stops controlling the electromagnetic pulse valve 33 and the electric pressure regulating valve 35, or directly controls the second valve 32 on the second pipeline 31 to close so that the second pipeline 31 no longer provides high-pressure gas for cleaning to the flow channel.
[0052] The memory mentioned above is electrically connected to the first controller 34, so that the parameters of the electromagnetic pulse valve 33, the electric pressure regulating valve 35 and the timer set corresponding to each coking situation can be stored in the memory, and when encountering the same coking situation, it can be called and controlled accordingly through the first controller 34, which is convenient and quick.
[0053] In some embodiments, see Figure 5 and Figure 6 As shown, the second pipeline assembly 3 further includes: a pressure gauge 37; the pressure gauge 37 is arranged in the second pipeline 31. In this way, it is convenient for the operator to confirm whether to adjust the flow state (such as pressure) of the high-pressure gas in the second pipeline 31 based on the pressure gauge 37, and if adjustment is required, the electric pressure regulating valve 35 can be adjusted through the first controller 34.
[0054] In some embodiments, see Figure 5 and Figure 6As shown, the second pipeline assembly 3 further includes: a high-pressure gas source 38; the high-pressure gas source 38 is connected to the inlet of the second pipeline 31. Here, the high-pressure gas source 38 is used to provide high-pressure gas to the second pipeline 31 to perform impact cleaning of coke in the flow channel of the burner 1, thereby reducing the time spent on connecting other high-pressure gas supply devices when cleaning the flow channel of the burner 1.
[0055] In the specific implementation of this embodiment, the high-pressure gas source 38 can use an industrial oxygen cylinder, which has a high pressure, supports combustion, and does not increase the nitrogen oxides in the exhaust gas.
[0056] In some embodiments, see Figure 3 As shown, the second pipeline 31 is vertically connected to the outer wall of the corresponding flow channel on the burner 1; or, see Figure 4 As shown, the second pipeline 31 is connected to the outer side wall of the corresponding flow channel on the burner 1 and forms an acute angle with the inlet of the corresponding flow channel of the burner 1.
[0057] Specifically, the second pipeline 31 mentioned above is vertically connected to the outer side wall of the corresponding flow channel on the burner 1, so that the gas flowing out of the outlet of the second pipeline 31 at a high speed hits the inner wall of the flow channel opposite to the outlet of the second pipeline 31, and then hits the inner wall of the flow channel corresponding to the outlet of the second pipeline 31 at a high speed in the opposite direction, so that the combustion-supporting gas can flow smoothly in the flow channel of the burner 1 during combustion.
[0058] The second pipeline 31 mentioned above is connected to the outer wall of the corresponding flow channel on the burner 1 and forms an acute angle with the inlet of the corresponding flow channel of the burner 1, so that the gas flowing out at a high speed from the outlet of the second pipeline 31 impacts the inner wall of the flow channel opposite to the outlet of the second pipeline 31, and then flows at a high speed and impacts the coke in the flow channel, so that the combustion-supporting gas can flow smoothly in the flow channel of the burner 1 during combustion.
[0059] In some specific embodiments, see Figure 1 and Figure 6 As shown, the combustion device includes:
[0060] A plurality of burners 1 are provided, each burner 1 having a flow channel.
[0061] There are multiple first pipeline assemblies 2, each of which includes: a first pipeline 21 and a first valve 22 arranged on the first pipeline 21, and the outlet of the first pipeline 21 of each first pipeline assembly 2 is connected to the inlet of a flow channel. The gas flowing in the first pipeline 21 is uncompressed oxygen for combustion support.
[0062] The second pipeline assembly 3 includes: a plurality of second pipelines 31, a plurality of second valves 32, an electromagnetic pulse valve 33, a first controller 34, an electric pressure regulating valve 35, a pressure gauge 37 and a high-pressure gas source 38.

[0064] The timer is electrically connected to the first controller 34 .
[0065] The memory is electrically connected to the first controller 34 .
[0066] When a certain burner 1 is found to be coked (or a certain burner 1 should be decoked as a regular operation), the pulse frequency of the electromagnetic pulse valve 33 is set by the first controller 34, the pressure of the electric pressure regulating valve 35 is set, and the decoking operation time is set by the timer; then the first valve 22 corresponding to the burner 1 that needs to be decoked is closed, and the corresponding second valve 32 is opened to start the decoking operation. After the decoking operation is completed, the corresponding second valve 32 is closed, and the corresponding first valve 22 is opened to resume the combustion of the burner 1.
[0067] In the present embodiment, during operation, high-pressure gas is used to perform pulse purging on the flow channel of the burner gun 1 to achieve the purpose of cleaning. Before the operation, different gas pressures, pulse frequencies, and operation times can be set according to the coking conditions of the burner gun 1. The cleaning effect is judged, and the decoking parameters that meet the cleaning effect requirements are screened out and saved in the memory. In the later decoking operation, the set decoking parameters can be directly used to perform the operation, which saves time and effort and reduces the impact of the decoking operation on the process.
