Abstract
Description
Technical Field
[0001] This application relates to the field of plasma ignition devices, and more particularly to an ignition device. Background Technology
[0002] In the oil, natural gas, and chemical industries, it is often necessary to emit waste gases, which usually contain combustible or toxic gases. In order to protect the environment and ensure safety, the waste gases need to be ignited and completely burned before being released into the atmosphere.
[0003] Existing venting methods typically use a plasma ignition device to ignite the exhaust gas. The plasma ignition device includes an intake pipe and a plasma generator. The intake pipe is used to allow the exhaust gas to pass through, and the plasma ignition device passes through the intake pipe and is installed on the intake pipe. The plasma ignition device generates heat through discharge, thereby igniting the combustible gas in the exhaust gas to form an open flame.
[0004] The aforementioned technical solutions have the following drawbacks: when the exhaust gas has poor flammability, it is difficult to ignite directly, resulting in a long ignition time. Utility Model Content
[0005] In order to improve the efficiency of plasma ignition devices in igniting exhaust gases, this application provides an ignition device.
[0006] The ignition device provided in this application adopts the following technical solution:
[0007] An ignition device includes an air inlet pipe, a plasma generator, and an auxiliary mechanism. The plasma generator passes through the air inlet pipe and is fixed to the air inlet pipe. The auxiliary mechanism is disposed in the air inlet pipe and is used to introduce combustion-supporting agent into the air inlet pipe.
[0008] By adopting the above technical solution, a plasma generator is installed in the intake pipe, allowing the gas to be ignited to be introduced into the intake pipe. After the plasma generator ignites the gas, an open flame is ejected from the end of the intake pipe. By installing an auxiliary mechanism on the intake pipe, the auxiliary mechanism can introduce fuel or other combustion aids into the intake pipe, thereby making the process of the plasma generator igniting the gas to produce an open flame take longer and improving ignition efficiency.
[0009] Optionally, several gas-gathering cylinders are installed inside the air intake pipe. The gas-gathering cylinders are cylindrical structures and are coaxially installed in the air intake pipe. The plasma generator passes through the air intake pipe and the gas-gathering cylinders.
[0010] By adopting the above technical solution, and by setting a gas-gathering cylinder in the air inlet pipe, the gas-gathering cylinder is coaxially set in the air inlet pipe. When the gas to be ignited flows in the air inlet pipe, the inner diameter of the air inlet pipe located at the plasma generator is smaller, so that the gas to be ignited is closer to the plasma generator, and the gas ignition process is more efficient.
[0011] Optionally, a heat-insulating filler is provided between the air intake pipe and the air-gathering cylinder.
[0012] By adopting the above technical solution, by setting a heat insulation filler between the air inlet pipe and the gas gathering cylinder, the heat insulation filler can slow down the heat transfer rate between the gas gathering cylinder and the air inlet pipe, thereby keeping the surface temperature of the air inlet pipe lower. When the combustion accelerant is injected into the air inlet pipe of the auxiliary mechanism box, the probability of the auxiliary mechanism being too hot and the combustion accelerant burning can be reduced.
[0013] Optionally, the auxiliary mechanism includes a nozzle and a solenoid valve. The nozzle passes through the air intake pipe and the air-gathering cylinder, and the solenoid valve is mounted on the nozzle and located outside the air intake pipe.
[0014] By adopting the above technical solution, by setting a nozzle on the air intake pipe, the combustion accelerator can enter the air intake pipe through the nozzle. By setting a solenoid valve on the nozzle, the solenoid valve can close after the combustion accelerator is sprayed into the air intake pipe, thereby reducing the probability of open flame in the air intake pipe igniting the combustion accelerator in the nozzle and causing an accident, and improving the safety of use.
[0015] Optionally, the nozzle includes multiple nozzles, connecting pipes, and a main pipe. The multiple nozzles are equidistantly spaced along the circumference of the air intake pipe and penetrate through the air intake pipe. The connecting pipe is a circular pipe and is coaxially sleeved outside the air intake pipe. The nozzles are connected to the connecting pipe, and the main pipe is connected to the connecting pipe. A solenoid valve is installed on the main pipe.
[0016] By adopting the above technical solution, multiple nozzles are set on the air intake pipe, and the nozzles are evenly arranged along the circumference of the air intake pipe, so that the combustion accelerator can be evenly distributed in the air intake pipe when it is injected into the air intake pipe. By setting a connecting pipe outside the air intake pipe, the connecting pipe is connected to multiple nozzles, so that the combustion accelerator can be conveniently supplied to multiple nozzles.
[0017] Optionally, an atomizer is installed on the main pipe.
[0018] By adopting the above technical solution, and by installing an atomizer on the main pipeline, the atomizer can atomize materials such as fuel into droplets, thereby improving the combustion efficiency of the combustion aid and further enhancing the combustion-supporting effect.
[0019] Optionally, a jet pipe is connected to the main pipe, which is used to inject gas into the nozzle.
[0020] By adopting the above technical solution, by installing a jet pipe on the main pipeline, gas can be injected into the jet pipe, thereby allowing the combustion accelerant in the jet pipe to enter the air intake pipe. After the combustion accelerant burns, the jet pipe continues to spray gas, thereby reducing the chance of open flame spreading in the jet pipe and enabling the burning combustion accelerant in the jet pipe to be sprayed out.
[0021] Optionally, an air valve is provided on the jet pipe to control the opening and closing of the jet pipe.
[0022] By adopting the above technical solution, an air valve is installed on the jet pipe to control the opening and closing of the jet pipe. When the combustion improver is injected into the jet pipe, the air valve closes, allowing the combustion improver to remain in the jet pipe. At this time, the atomizer can convert the liquid combustion improver into a mist droplets through vibration, thereby reducing fuel consumption.
[0023] In summary, the beneficial technical effects of this application are as follows:
[0024] 1. By installing a plasma generator in the intake pipe, the gas to be ignited is introduced into the intake pipe. After the plasma generator ignites the gas, an open flame is ejected from the end of the intake pipe. By installing an auxiliary mechanism on the intake pipe, the auxiliary mechanism can introduce fuel and other combustion aids into the intake pipe, thereby making the process of the plasma generator igniting the gas to produce an open flame take longer, thus improving the ignition efficiency.
[0025] 2. By installing a nozzle on the intake pipe, the combustion accelerator can enter the intake pipe through the nozzle. By installing a solenoid valve on the nozzle, the solenoid valve can close after the combustion accelerator is injected into the intake pipe, thereby reducing the probability of an open flame in the intake pipe igniting the combustion accelerator in the nozzle and causing an accident, thus improving the safety of use.
[0026] 3. By installing a jet pipe on the main pipeline, gas can be injected into the nozzle, thereby allowing the combustion accelerant in the nozzle to enter the air intake pipe. After the combustion accelerant burns, the jet pipe continues to spray gas, thereby reducing the chance of open flame spreading in the nozzle and expelling the burning combustion accelerant in the nozzle.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses an ignition device, as shown in the embodiments below. Figure 1 and Figure 2It includes an air inlet pipe 1, a plasma generator 2, and an auxiliary mechanism 3. The air inlet pipe 1 is a round metal tube with good heat resistance. The plasma generator 2 is installed in the air inlet pipe 1. The air inlet pipe 1 is used to introduce the gas to be ignited, so that the gas flows in the air inlet pipe 1. The plasma generator 2 is used to ignite the gas, so that a flame is ejected from the port of the air inlet pipe 1. The auxiliary mechanism 3 is installed on the air inlet pipe 1. The auxiliary mechanism 3 is used to introduce a combustion aid into the air inlet pipe 1, so that the plasma generator 2 can quickly ignite the gas and make the ignition process more efficient.
[0032] Reference Figure 1 and Figure 2 The intake pipe 1 contains several gas-gathering cylinders 11, each with a cylindrical structure. These cylinders are coaxially aligned with the intake pipe 1 and have a gradually increasing diameter. As the gas to be ignited flows within the intake pipe 1, the diameter of the cylinder gradually increases. A plasma generator 2 is installed at the smallest diameter gas-gathering cylinder 11. The main body of the plasma generator 2 is mounted outside the intake pipe 1, penetrating both the intake pipe 1 and the gas-gathering cylinders 11, thus enabling it to ignite the gas within the gas-gathering cylinders 11. When the plasma generator 2 is operating, the smaller diameter of the intake pipe 1 at the plasma generator 2 facilitates efficient and easy gas ignition. (Refer to...) Figure 1 A heat-insulating filler 12 is provided in the gap between the air intake pipe 1 and the air-gathering cylinder 11. The heat-insulating filler 12 is used for heat insulation, thereby reducing the temperature rise on the air intake pipe 1.
[0033] Reference Figure 1 and Figure 2 The auxiliary mechanism 3 includes a nozzle 31, which comprises multiple nozzles 311, a connecting pipe 312, and a main pipe 313. The multiple nozzles 311 are equidistantly spaced along the circumference of the intake pipe 1, passing through the intake pipe 1 and the gas-gathering cylinder 11, and are located on one side of the plasma generator 2. The connecting pipe 312 is a circular pipe structure, coaxially arranged with the intake pipe 1, and sleeved outside the intake pipe 1. The multiple nozzles 311 communicate with the connecting pipe 312. The main pipe 313 is located outside the intake pipe 1 and communicates with the connecting pipe 312. Fuel is introduced into the main pipe 313, and the fuel enters the multiple nozzles 311 through the connecting pipe 312, thereby improving the efficiency of the plasma generator 2 in igniting the gas.
[0034] Reference Figure 1 and Figure 2A solenoid valve 32 is installed on the main pipe 313 to control the opening and closing of the main pipe 313. When it is necessary to introduce combustion-supporting agent into the intake pipe 1, the solenoid valve 32 opens, allowing fuel and other combustion-supporting agents to enter the intake pipe 1. After the fuel is injected into the intake pipe 1, the solenoid valve 32 closes, isolating the fuel on one side of the solenoid valve 32. When the fire in the intake pipe 1 is large, it can reduce the probability of the fire spreading to the main pipe 313, thereby reducing the probability of the flame igniting the combustion-supporting agent in the main pipe 313 and improving safety.
[0035] Reference Figure 1 An atomizer 33 is installed on the main pipe 313, and the atomizer 33 is located between the main pipe 313 and the connecting pipe 312. The atomizer 33 can be an ultrasonic atomizer, which uses ultrasonic vibration to convert the liquid into a mist-like droplets, further improving the combustion-supporting effect.
[0036] Reference Figure 1 A jet pipe 34 is connected to the main pipe 313, which is used to inject gas into the nozzle 31. When the solenoid valve 32 is opened, fuel enters the nozzle 31. At this time, the solenoid valve 32 closes, and the atomizer 33 is activated, enabling the fuel in the nozzle 31 to be atomized. The jet pipe 34 injects gas, allowing the atomized fuel to enter the intake pipe 1, thereby achieving a combustion-supporting effect. A gas valve 35 is provided on the jet pipe 34, which is used to control the opening and closing of the jet pipe 34. When the fuel enters the nozzle 31 but has not yet been fully atomized, the gas valve 35 remains closed, allowing the fuel to be continuously atomized in the nozzle 31.
[0037] The implementation principle of this application embodiment is as follows: By setting a plasma generator 2 in the intake pipe 1, the plasma generator 2 is used to ignite the gas in the intake pipe 1, so that the flame is sprayed out from the end of the intake pipe 1. By setting an auxiliary mechanism 3 in the intake pipe 1, the fuel can enter the intake pipe 1 through the nozzle 31, thereby playing a combustion-supporting role and improving the efficiency of igniting the gas. By setting a solenoid valve 32 on the main pipe 313, the solenoid valve 32 can isolate the fuel in the main pipe 313, thereby reducing the probability of the flame igniting the fuel in the nozzle 31 and spreading to the main pipe 313, and improving the safety of use.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
