Description

Technical Field

[0001] This invention relates to the field of flare technology in the petrochemical and coal chemical industries, specifically to a float-type adjustable flow flare head and its adjustment method. Background Technology

[0002] The sources of exhaust gases that require environmental protection treatment in industries such as petrochemicals and coal chemicals are diverse, the composition of the exhaust gases is complex, and the volume varies greatly; in addition, the amount of exhaust gas released varies greatly due to different accident conditions.

[0003] In the owner's emergency exhaust gas flare treatment project, due to site and other issues, a ground flare system capable of handling multiple operating conditions was not suitable, and only an elevated flare system could be used. The exhaust gas in the exhaust pipe consists of intermittent exhaust gases generated by various accidents under different operating conditions, with large differences in venting volume. Using a conventional flare head cannot adjust the flare head according to the real-time venting volume. If the flare is designed for low venting volume, when multiple accidents occur simultaneously, the exhaust gas volume will be extremely large, resulting in an excessively high exhaust gas Mach number. Consequently, the exhaust gas cannot be fully combusted, leading to failure to meet environmental protection standards. On the other hand, if the flare is designed for large venting volume emission of multiple operating conditions occurring simultaneously, when a single accident occurs, the gas volume will be too small, resulting in a low gas flow rate and low exhaust pressure. This may lead to incomplete emission or backfire, causing equipment damage. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art by proposing a float-type adjustable flow torch head and adjustment method, with the aim of safely and environmentally discharging multi-component exhaust gases and adapting to different gas emission conditions.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution.

[0006] A float-type adjustable flow torch head includes a frustum torch head, a high-temperature resistant suspended ball, a support module, and a drive device. The frustum torch head is a hollow, inverted frustum structure, with open top and bottom. An air supply channel is connected to the bottom of the frustum torch head. The high-temperature resistant suspended ball is located inside the frustum torch head but is not connected to it. Support modules are evenly distributed around the high-temperature resistant suspended ball, and the high-temperature resistant suspended ball is placed on the support modules. The support modules are connected to the drive device. Under the action of the drive device, the high-temperature resistant suspended ball and the support modules move up and down together.

[0007] Furthermore, the control device of the drive unit is installed in the ground control cabinet and connected to the central control room.

[0008] Furthermore, the drive device is connected to the support frame of the torch head.

[0009] Furthermore, the driving device is a pneumatic or hydraulic device.

[0010] Furthermore, a torch head baffle is installed above the pedestal torch head.

[0011] Furthermore, the support module has an arc-shaped track on the side facing the high-temperature resistant suspended ball, and the high-temperature resistant suspended ball is slidably connected to the arc-shaped track on the support module. A limit block is provided at the bottom of the support module to prevent the high-temperature resistant suspended ball from falling. Both the bottom and top of the support module are located inside the frustum torch head.

[0012] Furthermore, both sides of the truss head are equipped with a continuous lamp and a flame transmitter.

[0013] Furthermore, the eternal flame and flame transmitter extend into and are installed inside the truncated cone torch head.

[0014] Based on a method for adjusting a float-type adjustable flow torch head, the bottom of the high-temperature resistant suspended ball is supported by a support module, forming a space at the bottom of the high-temperature resistant suspended ball for small-volume gas discharge, which meets the needs of small-volume gas discharge conditions. When a large volume of gas is discharged, the high-temperature resistant suspended ball is lifted, so that the outlet space meets the needs of large-volume gas discharge. In cases where the upstream process does not support venting to high pressure, the support module is manually adjusted for venting capacity via a drive device. By adjusting the rise and fall of the drive device, the height of the high-temperature resistant suspended ball is adjusted to regulate the venting of the torch head.

[0015] The beneficial effects of this invention compared to the prior art are as follows:

[0016] The flare head described in this invention can meet various working conditions. Regardless of the gas volume, the flare head can be adjusted according to the venting volume. When the gas volume is small, the space supported by the support module is sufficient to meet the emission requirements of low venting volume. When the emission gas volume increases, the venting capacity of the flare head can be adjusted by adjusting the height of the high-temperature resistant suspension ball by adjusting the pressure of the emission gas, so as to adapt to different emission gas volumes.

[0017] The venting capacity of the flare head is adjusted by regulating the rise and fall of the pneumatic or hydraulic device to control the height of the high-temperature resistant suspended ball. The control unit for the pneumatic or hydraulic device is installed in a ground control cabinet and connected to the central control room, allowing personnel to adjust the venting capacity of the flare head on-site or in the central control room. This prevents large amounts of vented air from occurring in sudden accident situations, which require rapid handling and discharge; the venting volume of the flare head can be manually adjusted.

[0018] 1. It solves the problem of insufficient combustion of small exhaust gases by large-volume flare heads, reducing environmental pollution and meeting environmental emission requirements.

[0019] 2. In new projects, a single flare head can handle emissions of varying volumes. Compared to conventional flare heads, different diameter exhaust pipes and flare heads are required for operating conditions with significantly different emission volumes. This reduces the owner's costs for piping and flare head procurement and installation.

[0020] 3. The float-type adjustable flow torch head can be installed in existing projects. After designing the float-type adjustable flow torch head according to the minimum emission gas, only the old torch head needs to be replaced to meet the operating conditions of maximum and minimum emission, which greatly saves the owner's renovation costs.

[0021] 4. The float-type adjustable flow torch head can effectively prevent backfire of exhaust gas combustion and effectively protect upstream pipelines and equipment.

[0022] 5. The float-type adjustable flow torch head allows for real-time manual adjustment of the venting volume, preventing insufficient real-time venting volume during upstream process pressure buildup and emergency venting. Attached Figure Description

[0028] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0029] Example 1

[0030] like Figure 1 and Figure 2As shown, this embodiment proposes a float-type adjustable flow torch head and its adjustment method, including a frustum torch head 1, a high-temperature resistant suspended ball 2, a support module 6, and a driving device. The frustum torch head 1 is a hollow inverted frustum structure, with open top and bottom. An air supply channel 10 is connected to the bottom of the frustum torch head 1. The high-temperature resistant suspended ball 2 is located inside the frustum torch head 1 but is not connected to it. Support modules 6 are evenly distributed around the high-temperature resistant suspended ball 2, and the high-temperature resistant suspended ball 2 is placed on the support modules 6. The support modules 6 are connected to the driving device. Under the action of the driving device, the high-temperature resistant suspended ball 2 and the support modules 6 move up and down together. In this embodiment, the driving device is a pneumatic or hydraulic device 7. The pneumatic or hydraulic device 7 is connected to the support frame 9 of the torch head. The control device of the pneumatic or hydraulic device 7 is installed in a ground control cabinet and connected to the central control room.

[0031] A torch head baffle 3 is installed above the pedestal torch head 1. A continuous lamp 4 and a flame transmitter 5 are installed on the top of both sides of the pedestal torch head 1. The continuous lamp 4 and the flame transmitter 5 are also connected to the support frame 9.

[0032] The flare head described in this embodiment can meet various working conditions. Regardless of the gas volume, the flare head can be adjusted according to the venting volume. When the gas volume is small, the high-temperature resistant suspended ball 2 is located on the support module 6. The space supported by the support module 6 is sufficient to meet the emission requirements of low venting volume. When the emission gas volume increases, the emission gas enters the frustum flare head 1 through the gas supply channel 10. The high-temperature resistant suspended ball 2 is lifted up under the action of the emission gas pressure, and the space for emission gas combustion increases. Therefore, the venting capacity of the flare head can be adjusted by adjusting the height of the high-temperature resistant suspended ball 2 according to the emission gas pressure to adapt to different emission gas volumes.

[0033] The support module 6 can also manually adjust the venting capacity via a pneumatic or hydraulic device 7. The support module 6 is connected to the drive rod of the pneumatic or hydraulic device 7. By adjusting the rise and fall of the pneumatic or hydraulic device 7, the height of the high-temperature resistant suspended ball 2 is adjusted to regulate the venting capacity of the flare head. The control device of the pneumatic or hydraulic device 7 is installed in a ground control cabinet and connected to the central control room, allowing personnel to adjust the venting capacity of the flare head on-site or in the central control room. This can prevent large amounts of vented air from occurring in sudden accident situations, which require rapid processing and discharge. Relying solely on the autonomous rise of the high-temperature resistant suspended ball 2 may lead to problems such as pressure buildup or insufficient real-time venting at the front end of the air-raid shelter. In such cases, the venting capacity of the flare head can be manually adjusted. For flare heads in existing flare projects, only the flare head described in this embodiment needs to be replaced to meet both low-emission and high-emission conditions, without replacing the entire flare pipeline, greatly reducing the owner's renovation costs.

[0034] The torch head baffle 3 acts as a limiter, preventing the high-temperature resistant suspended ball 2 from flying out of the torch head, thus providing a safety function. The continuous light 4 and the flame transmitter 5 are installed on the top of the torch head and are installed by extending into the torch head, so that even when a small amount of gas is emitted, it can be burned and processed immediately.

[0035] Example 2

[0036] See Figure 3 This embodiment proposes a float-type adjustable flow torch head. The main structure is the same as in Embodiment 1, except for the structure of the support module 6. In this embodiment, the support module 6 has an arc-shaped track on the side facing the high-temperature resistant suspended ball 2. The high-temperature resistant suspended ball 2 is slidably connected to the arc-shaped track on the support module 6. A limit block 8 is provided at the bottom of the support module 6 to prevent the high-temperature resistant suspended ball 2 from falling. Both the bottom and top of the support module 6 are located inside the frustum-shaped torch head 1. This structure provides a more stable support form for the support module 6. When the exhaust gas pressure increases, the high-temperature resistant suspended ball 2 slides along the arc-shaped track on the support module 6, and the limit block 8 at the bottom further protects it, effectively improving the stability of the high-temperature resistant suspended ball 2's vertical movement.

[0037] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all of these should be considered to fall within the scope of patent protection determined by the submitted claims.
