Description

Technical Field

[0001] This invention relates to the field of sootblower technology, and more particularly to an energy-saving acetylene shockwave sootblower. Background Technology

[0002] A soot blower is a device used on the heating surface of a boiler to remove ash from the heating surface. The working principle of the acetylene shock wave soot blower is to mix oxygen and combustible gas acetylene in an appropriate ratio in a container, and after ignition, it produces a deflagration. The huge sound energy and high temperature and high speed gas generated in an instant vibrate in the form of shock waves, which impact and wash the heating surface, so as to achieve the soot blowing and cleaning effect.

[0003] Chinese Patent CN 205939181 U discloses a novel pneumatic pulse soot blower, comprising a generator and an air inlet pipe. The air inlet pipe is connected to the generator via an inflation pipe. The inflation pipe is equipped with a solenoid valve for inflating the generator and a check valve to prevent backflow of gas. A quick-release valve is provided at the generator's nozzle to control the ejection of gas from the generator. The air inlet pipe drives the piston rod of a cylinder and a baffle fixed to the front end of the piston rod to move back and forth via a cylinder control valve. The quick-release valve is connected to or closed by the generator through the baffle. This invention features a simple structure, easy operation, and high production efficiency.

[0004] However, this technical solution still has some problems. Shockwave soot blowing sometimes requires multiple operations. After one deflagration, gas is continuously introduced into the generator to prevent further ignition and deflagration. After the mixed gas in the generator deflagrations, the high-temperature gas flow generated tends to flow back into the generator, which can cause premature ignition of the gas inside the generator, posing safety hazards and gas waste. The above technical solution uses a quick-release valve to control the connection between the generator and the furnace body. However, the impact force of the deflagration gas flow is large, and this valve is not stable enough and is easily damaged by the impact force, resulting in unstable operation and safety hazards. In actual operation, there have been cases where the valve was knocked off by the impact of the deflagration gas flow. In addition, when introducing gas into the sealed generator, the gas needs to be... Pressurization is problematic because the proportions of the mixed gases differ significantly. For example, in the deflagration of an oxygen-acetylene mixture, the volume of oxygen is much greater than that of acetylene. When both oxygen and acetylene are simultaneously introduced into the generator, the oxygen flow rate is much higher than that of acetylene. This makes it more difficult for acetylene to enter the generator, making it harder to control the acetylene delivery rate. Unstable gas supply directly affects the deflagration effect and leads to significant gas waste, resulting in insufficient energy efficiency. While using large-diameter pipes can alleviate the charging difficulty to some extent, the effect is limited, and the pipes are easily damaged by the reaction force of the deflagration gas flow within the generator. The larger the pipe diameter, the greater the reaction force of the deflagration gas flow on the pipe. The aforementioned technical solutions have not effectively solved these problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an energy-saving acetylene shockwave sootblower. This invention controls the connection between the generator and the furnace body by setting an adjustable seal, buffers and protects the seal and sootblower by setting a damping component in the drive assembly, and balances the mixed gas and protects the gas delivery pipeline by setting a gas balance unit. This solves the problems of safety hazards and insufficient energy saving in sootblowers during operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An energy-saving acetylene shock wave soot blower, comprising:

[0008] A generator used to carry out deflagration reactions;

[0009] Injector nozzle used to expel the gas flow after deflagration;

[0010] A control unit for controlling the communication state between the generator and the injection port; and

[0011] A gas delivery unit for quantitatively delivering mixed gas into the generator;

[0012] The control unit controls the generator to connect with the injection port at a fixed distance and ignites the combustible gas in the generator. The expansion of the gas in the generator fully opens the control unit, causing the gas after deflagration in the generator to be ejected through the injection port.

[0013] Specifically, the injection port is installed outside the boiler furnace and connected to the area inside the boiler to be cleaned; the gas conveyed in the conveying unit can be a mixture of oxygen and acetylene or oxygen and natural gas, preferably oxygen and acetylene. When the oxygen and acetylene in the generator reach a certain volume, the mixture is ignited to produce deflagration.

[0014] The control unit can adopt a valve structure controlled by a cylinder. The valve is used to control the opening and closing of the injection port. The cylinder is equipped with a first magnetic switch to confirm the valve's open position. The magnetic switch sends a signal to the igniter.

[0015] In the initial state, the control unit seals the injection port to prevent the gas inside the generator from escaping through the injection port, thus avoiding gas loss during the charging process and reducing gas consumption. Since the generator is filled with a fixed amount of mixed gas, the gas usage is more stable in the fixed volume deflagration method, which can reduce the amount of mixed gas used and at the same time ensure the stable emission of shock waves.

[0016] After a certain amount of mixed gas is filled into the generator, the control unit opens the injection port. After the injection port is opened, the igniter is immediately started to ignite and deflagrate the mixed gas in the generator. The gas flow after deflagration is injected into the furnace body through the injection port for soot blowing and cleaning.

[0017] Soot blowing typically requires multiple deflagrations. After one deflagration, the control unit re-seals the nozzle. After the gas flow inside the generator is rapidly ejected, a negative pressure is formed inside, and the gas flow outside the generator tends to flow into the generator. By setting the control unit to seal the nozzle, the gas that continues to be charged into the generator is prevented from escaping, and the high-temperature gas flow from the previous deflagration is also prevented from flowing back into the generator through the nozzle. This improves the gas flow back after deflagration, which causes the gas inside the generator to be ignited prematurely, posing a safety hazard and wasting gas.

[0018] During operation, the generator only connects to the outside through the nozzle when the airflow is being sprayed. In other states, especially during inflation, the generator remains sealed, effectively reducing gas loss during inflation, improving gas utilization, reducing gas consumption, and saving operating costs.

[0019] The generator can adopt a traditional open cylindrical structure with a nozzle. The control unit and the air delivery unit can be installed between the inner cavity of the cylinder and the nozzle, depending on the specific situation. Therefore, this solution is also suitable for modifying traditional sootblowers so that they can continue to be used, thereby reducing operating costs.

[0020] As a preferred embodiment, the control unit includes:

[0021] A control pipe that connects the injection port to the generator;

[0022] A seal located inside the control tube to seal the injection port; and

[0023] A drive unit for controlling the movement of the seal.

[0024] Specifically, the seal can be made of high-temperature resistant and impact-resistant metal plate, and the seal is used to seal the inside of the control tube.

[0025] The seal can be slidably installed inside the control pipe or a hinged structure like a door. The installation of the seal should be sufficient to allow the injection port to be opened and closed.

[0026] The control unit also includes a positioning member for controlling the displacement of the drive unit, the positioning member being disposed on one side of the drive unit;

[0027] The positioning element can be a limit switch mounted on the cylinder to control the piston rod.

[0028] As another preferred embodiment, the drive unit includes:

[0029] An adjusting rod movable within the control tube; and

[0030] A drive assembly for moving the adjusting rod;

[0031] The sealing element is fixedly mounted on the adjusting rod;

[0032] After the seal moves toward the generator, it isolates the injection port from the generator.

[0033] Specifically, the drive assembly can be a cylinder device, which includes a cylinder barrel and a piston rod. The piston rod and the adjusting rod are connected as one unit by a pin. The injection port is located on the left side of the generator. In the initial state, the piston rod pushes the adjusting rod to the right, causing the seal to move to the right side of the injection port, thus isolating the injection port from the generator.

[0034] When the gas in the generator reaches the deflagration requirement, the starting cylinder drives the seal to move to the left, causing the injection port to open. After the injection port opens a gap, the igniter is immediately started.

[0035] After the gas inside the generator explodes, the resulting high-speed airflow is ejected outward through the nozzle. At the same time, the airflow pushes the seal to the left, which helps the seal move and makes the nozzle fully open.

[0036] After the high-speed airflow is ejected from the generator, the starting cylinder pushes the seal to the right again to seal the injection port, so that the next round of charging and combustion can begin.

[0037] As a preferred embodiment, the drive assembly includes a damping element that buffers the adjusting rod.

[0038] Specifically, when the drive assembly uses a cylinder device, the space between the left side of the piston rod and the cylinder is filled with gas, and the stroke of the piston rod is less than the length of the cylinder.

[0039] With this setup, when the airflow in the generator pushes the piston rod to the left, there is still a gap between the piston rod and the inner left wall of the cylinder. The air pressure in this gap acts as a damping element, which buffers the piston rod and prevents the seal from directly hitting the control tube and the piston rod from hitting the cylinder, thereby protecting the cylinder, seal, control tube and other components.

[0040] In addition, ignition occurs after opening a notch in the injection port. Part of the high-speed gas flow generated by the deflagration is ejected through the injection port, while another part pushes the seals and cylinder to the left, thus dispersing the impact force of the deflagration and further improving the protection of components such as the cylinder, seals, and control pipes.

[0041] By designing the piston rod's travel distance and utilizing the gas between the piston rod and the cylinder for buffering and protection, no additional protective structure is needed, making the cylinder more versatile and reducing operating costs.

[0042] As another preferred embodiment, the gas delivery unit includes:

[0043] Gas supply pipe one and gas supply pipe two, which respectively supply different gases to the generator; and

[0044] A gas balance unit for balancing gas mixtures;

[0045] The gas in the first gas supply pipe and the second gas supply pipe is sent into the gas balance unit for mixing and then sent into the generator.

[0046] The gases in the first and second gas supply pipes are quantitatively mixed in the generator and then ignited to produce a deflagration.

[0047] Specifically, gas supply pipe one is used to transport oxygen, and gas supply pipe two is used to transport acetylene. Oxygen and acetylene enter the generator through the gas balance unit.

[0048] As a preferred embodiment, the gas balance unit comprises:

[0049] An air inlet pipe connected to the first air supply pipe and the second air supply pipe; and

[0050] An exhaust pipe connected to the generator;

[0051] The inner diameter of the air outlet pipe is reduced.

[0052] Specifically, the gas in the gas pipeline enters the generator along the negative Z-axis, and the gas balance unit has a shape in which the inner diameter gradually decreases along the negative Z-axis.

[0053] When supplying gas to the generator, the oxygen flow rate is greater than that of acetylene. By setting up a gas balance unit with a smaller pipe diameter, according to the Venturi effect, the high-speed flowing oxygen will simultaneously adsorb the acetylene flow, which plays a role in balancing the gas flow rate. This makes it easier for acetylene to enter the generator, improving the problem that acetylene is not easy to mix into the generator due to its low flow rate during the process of charging the mixed gas, and reducing the power required to input acetylene.

[0054] In addition, because the gas outlet pipe of the gas balance unit has a small diameter, it can reduce the force of the gas in the generator on the gas delivery pipeline after deflagration, thus protecting the pipeline components in the gas delivery unit and making it safer to use.

[0055] As another preferred embodiment, the control unit further includes a positioning plate to improve the stability of the movement of the adjusting rod.

[0056] Specifically, the positioning plate can be fixedly installed in the control tube or installed inside the generator, and the adjusting rod passes through the positioning plate and is inserted into the controller; the positioning plate has a channel for the airflow from the generator to enter the controller.

[0057] By setting a positioning plate to position and guide the adjusting rod, the stability of the adjusting rod's movement is improved, and the problem of the adjusting rod easily shaking and getting stuck after being impacted by the explosion gas flow is alleviated.

[0058] As a preferred embodiment, the piston rod in the drive assembly is provided with a spring. When the airflow in the generator pushes the piston rod to the left, the gas in the cylinder and the spring act as damping elements to buffer the push rod and further improve the protection effect.

[0059] The beneficial effects of this invention are as follows:

[0060] (1) The present invention opens and closes the generator by setting an adjustable sealing element to prevent the gas flow from returning to the generator. The method of adding mixed gas in a fixed quantity and volume to the generator can reduce the amount of mixed gas used and ensure the stable emission of shock wave.

[0061] (2) The present invention uses a cylinder to push the seal to move. The air pressure between the piston rod and the cylinder barrel can be used as a damping element to buffer the impact force generated by the deflagration in the generator, and prevent the seal from directly hitting the control tube and the piston rod from hitting the cylinder barrel. This protects the cylinder, seal and control tube and other components without the need for additional protective structures, making the cylinder multifunctional and reducing the cost of use.

[0062] (3) The present invention isolates the injection port and the generator by setting a movable seal. When the seal moves, the injection port opens a gap before ignition. Part of the high-speed airflow generated by the deflagration is ejected through the injection port, and part of it pushes the seal and cylinder to the left, which reduces the deflagration impact force on the soot blower and further improves the protection effect on components such as cylinder, seal and control tube.

[0063] (4) This invention balances the mixed gas by setting a gas balance unit with a smaller pipe diameter. The high-speed flowing oxygen will adsorb the acetylene flow, increasing the acetylene flow rate and making it easier for acetylene to enter the generator. This improves the problem that acetylene is not easy to mix into the oxygen due to its low flow rate during the filling of the mixed gas, and reduces the power consumption required to input acetylene. Since the filling of acetylene is easier to control, the ratio and volume of oxygen and acetylene in the mixed gas can be controlled more accurately, thereby improving the deflagration effect and improving the problem of increased soot blowing and gas consumption caused by the difficulty in controlling the gas in the traditional method.

[0064] (5) By making the outlet pipe of the gas balance unit narrow, the present invention can reduce the reaction force of the gas in the generator on the gas transmission pipeline after deflagration, thus protecting the pipeline in the gas transmission unit and making it safer to use.

[0065] In summary, the present invention has advantages such as safety, energy saving, and stable soot blowing. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0073] Example 1

[0074] like Figure 1-3 As shown, this embodiment provides an energy-saving acetylene shock wave sootblower, comprising:

[0075] Generator 1 for conducting deflagration reaction;

[0076] Injector 2 is used to discharge the gas flow after deflagration;

[0077] A control unit 3 for controlling the communication state between the generator 1 and the injection port 2; and

[0078] Gas delivery unit 4 for quantitatively delivering mixed gas into the generator 1;

[0079] The control unit 3 controls the generator 1 to communicate with the injection port 2 at a fixed distance and then ignites the combustible gas in the generator 1. The gas in the generator 1 expands and fully opens the control unit 3, so that the gas after the explosion in the generator 1 is ejected through the injection port 2.

[0080] Specifically, nozzle 2 is connected to the area to be cleaned; the gas transported in the conveying unit can be a mixture of oxygen and acetylene, air and acetylene, or oxygen and natural gas. The instruction manual uses a mixture of oxygen and acetylene as an example. When the acetylene mixed in the oxygen reaches a certain proportion, the mixture is ignited to produce deflagration.

[0081] The control unit 3 may adopt a valve structure controlled by a cylinder. The valve is used to control the opening and closing of the injection port 2. The cylinder is equipped with a first magnetic switch to confirm the valve opening position. The magnetic switch sends a signal to the igniter.

[0082] In the initial state, the control unit 3 seals the injection port 2 to prevent the gas in the generator 1 from escaping through the injection port 2, thus avoiding gas loss during the charging process and reducing gas consumption. Since the sealed generator 1 is filled with a fixed amount of mixed gas, the gas usage is more stable in the fixed volume deflagration method, which can reduce the amount of mixed gas used, while ensuring the stable emission of shock waves and more stable soot blowing.

[0083] After a certain amount of mixed gas is filled into the generator 1, the control unit 3 opens the injection port 2. After the injection port 2 is opened, the igniter is immediately started to ignite and deflagrate the mixed gas in the generator 1. The gas flow after deflagration is injected into the furnace body through the injection port 2 for soot blowing and cleaning.

[0084] By sealing the injection port 2 with the control unit 3, after a deflagration, the high-temperature gas flow from the previous deflagration can be prevented from flowing back into the generator 1 through the injection port 2. At this time, gas can continue to be injected into the generator 1, which improves the gas flow back after the deflagration. This causes the gas in the generator 1 to be ignited prematurely, which poses a safety hazard and wastes gas. This further saves gas consumption.

[0085] During operation, the generator 1 is only connected to the outside through the injection port 2 when the gas flow is being injected. In other states, the generator 1 is always in a sealed state. During the inflation process, this reduces gas loss and after deflagration, it prevents the deflagration gas flow from flowing back into the generator 1.

[0086] The generator 1 can adopt a traditional open cylindrical structure with a jet nozzle 2. The control unit 3 and the air supply unit 4 can be installed between the inner cavity of the cylinder and the jet nozzle 2, depending on the specific situation. Therefore, this solution is also applicable to the modification of traditional soot blowers so that traditional soot blowers can continue to be used, thereby reducing the cost of use.

[0087] like Figure 2-3 As shown, the control unit 3 further includes:

[0088] The control pipe 31 connects the injection port 2 to the generator 1;

[0089] A sealing element 32, which is located inside the control tube 31, is used to seal the injection port 2; and

[0090] The drive unit 33 is used to control the movement of the seal 32.

[0091] Specifically, the seal 32 can be made of a high-temperature resistant and impact-resistant metal plate, and the seal 32 is used to seal the inside of the control tube 31.

[0092] The seal 32 can be slidably installed inside the control pipe 31 or it can be a hinged structure like a door. The installation of the seal 32 should be sufficient to allow the spray nozzle 2 to be opened and closed.

[0093] The control unit 3 further includes a positioning member 36 for controlling the displacement of the drive unit 33, the positioning member being disposed on one side of the drive unit 33;

[0094] The positioning element 36 can be a limit switch installed on the cylinder to control the piston rod 3322. After the gas is filled inside the generator 1, the cylinder drives the seal 32 to move to the left by a certain distance, so that the injection port 2 opens the gap, and then the igniter is started to ignite and deflagrate the mixed gas in the generator 1. The positioning element 36 can also be used to control the start of the igniter at the same time.

[0095] After the piston rod 3322 moves to the left to the position of the positioning member 36, the cylinder can continue to work, driving the sealing plate 32 to move to the left, so that the injection port 2 is fully opened; the cylinder can also stop working, and the impact airflow in the generator 1 drives the sealing plate 32 to move to the left, so that the injection port 2 is fully opened.

[0096] like Figure 2-3 As shown, further, the drive unit 33 includes:

[0097] The adjusting rod 331, which is movable within the control tube 31; and

[0098] Drive assembly 332 for driving the adjustment rod 331 to move;

[0099] The sealing element 32 is fixedly mounted on the adjusting rod 331;

[0100] After the seal 32 moves toward the generator 1, it isolates the injection port 2 from the generator 1.

[0101] Specifically, the drive assembly 332 can be a cylinder device, which includes a cylinder barrel 3321 and a piston rod 3322. The piston rod 3322 and the adjusting rod 331 are connected as one unit by a pin. The injection port 2 is located on the left side of the generator 1. In the initial state, the piston rod 3322 pushes the adjusting rod 331 to the right, so that the seal 32 moves to the right side of the injection port 2, separating the injection port 2 from the generator 1.

[0102] When the gas inside generator 1 reaches the deflagration requirement, the starting cylinder drives the seal 32 to move to the left, causing the injection port 2 to open. After the injection port 2 opens a gap (such as...), Figure 3 As shown in section b: after the seal 32 moves to the left, the connection between the right side of the seal 32 and the injection port 2 is a notch, and the igniter is activated immediately;

[0103] After the gas inside the generator 1 explodes, the resulting high-speed airflow is ejected outward through the nozzle 2. At the same time, the airflow pushes the seal 32 to the left, which helps the seal 32 to move and makes the nozzle 2 fully open.

[0104] After the high-speed airflow in generator 1 is ejected, the starting cylinder pushes the seal 32 to the right again, sealing the injection port 2 in order to carry out the next round of inflation and combustion.

[0105] like Figure 3 As shown, the drive assembly 332 further includes a damping element 333 for buffering the adjusting rod 331.

[0106] Specifically, when the drive assembly 332 uses a cylinder device, the space between the left side of the piston rod 3322 and the cylinder 3321 is filled with gas, and the stroke of the piston rod 3322 is less than the length of the cylinder 3321.

[0107] With this configuration, when the airflow in the generator 1 pushes the piston rod 3322 to the left, there is still a gap between the piston rod 3322 and the inner left wall of the cylinder 3321. The air pressure in this gap is the damping element 333, which buffers the piston rod 3322 and prevents the seal 32 from directly hitting the control tube 31 and the piston rod 3322 from hitting the cylinder 3321, thereby protecting the cylinder, seal 32 and control tube 31 and other components.

[0108] In addition, after ignition is performed by opening a gap in the nozzle 2, part of the high-speed airflow generated by the deflagration is ejected through the nozzle 2, and part of it pushes the seal 32 and the cylinder to the left, which reduces the deflagration impact force on the soot blower and further improves the protection effect on components such as the cylinder, seal 32 and control pipe 31.

[0109] By designing the travel distance of the piston rod 3322, the gas between the piston rod 3322 and the cylinder 3321 is used for buffering and protection, eliminating the need for additional protection structures. This makes the cylinder more versatile and reduces operating costs.

[0110] like Figure 4 As shown, furthermore, the gas delivery unit 4 includes:

[0111] Gas supply pipe 41 and gas supply pipe 42 respectively supply different gases to generator 1; and

[0112] Gas balance unit 43 for balancing the gas mixture;

[0113] The gas in the first gas supply pipe 41 and the second gas supply pipe 42 is sent into the gas balance unit 43 for mixing and then sent into the generator 1.

[0114] The gases in the first gas supply pipe 41 and the second gas supply pipe 42 are quantitatively mixed in the generator 1 and then ignited to produce a deflagration.

[0115] Specifically, gas supply pipe 41 is used to transport oxygen, gas supply pipe 42 is used to transport acetylene, and oxygen and acetylene enter generator 1 via gas balance unit 43.

[0116] like Figure 5 As shown, the gas balance unit 43 further includes:

[0117] An air inlet pipe 431 connected to the first air supply pipe 41 and the second air supply pipe 42; and

[0118] The air outlet pipe 432 is connected to the generator 1;

[0119] The inner diameter of the air outlet pipe 432 is reduced.

[0120] Specifically, the gas in the gas pipeline enters the generator 1 along the negative Z-axis, and the gas balance unit 43 is shaped with its inner diameter gradually decreasing along the negative Z-axis.

[0121] When gas is supplied to generator 1, the oxygen flow rate is greater than the acetylene flow rate. By setting up a gas balance unit 43 with a smaller pipe diameter, according to the Venturi effect: when a fluid passes through a narrowed flow cross section, the flow rate increases. The increase in flow rate is accompanied by a decrease in fluid pressure. Therefore, a low pressure is generated near the high-speed flowing fluid, resulting in adsorption. The high-speed flowing oxygen will simultaneously adsorb the acetylene flow, increasing the acetylene flow rate and making it easier for acetylene to enter generator 1. This improves the problem that acetylene is not easy to mix with oxygen due to its low flow rate during the filling of the mixed gas, reduces the power required to input acetylene, and because the filling of acetylene is easier to control, the ratio of oxygen to acetylene in the mixed gas can be better controlled, thereby improving the deflagration effect.

[0122] In addition, since the gas outlet pipe 432 of the gas balance unit 43 has a small diameter, it can reduce the reaction force of the gas in the generator 1 on the gas transmission pipeline after deflagration, thus protecting the pipeline in the gas transmission unit 4 and making it safer to use.

[0123] like Figure 2-3 As shown, the control unit 3 further includes a positioning plate 34 to improve the movement stability of the adjusting rod 331.

[0124] Specifically, the positioning plate 34 includes two plates on both sides of the injection port 2. The positioning plate 34 can be fixedly installed in the control tube 31 or installed in the generator 1. The adjusting rod 331 passes through the positioning plate 34 and is inserted into the controller 31. The right side plate of the positioning plate 34 is provided with a channel for the airflow in the generator 1 to enter the controller 31. Preferably, during the movement of the adjusting rod 331, the right end of the adjusting rod 331 is always inserted into the positioning plate 34.

[0125] By setting a positioning plate 34 to position and guide the adjusting rod 331, the stability of the movement of the adjusting rod 331 is improved, and the problem of the adjusting rod 331 easily shaking and getting stuck after being impacted by the explosion gas flow is improved.

[0126] like Figure 1 As shown, it also includes a pressure stabilizing unit 5 for stabilizing the pressure of the generator 1; the pressure stabilizing unit 5 is connected to the generator 1.

[0127] Specifically, the pressure stabilizing unit 5 is a pressure stabilizing pipe installed on the generator. The generator 1 is connected to the outside world through the pressure stabilizing pipe, which is a small-diameter pipe. By setting up the pressure stabilizing pipe, the internal pressure of the generator 1 is balanced during the inflation process. This improves the problem that when the generator 1 is completely sealed, the internal pressure of the generator 1 increases as gas is added, making it difficult to continue adding gas. Because the pressure stabilizing pipe is a small-diameter thin pipe, the amount of gas leaking out of the generator through the pressure stabilizing pipe is very small and can be ignored, and does not affect the gas filling operation of the generator 1.

[0128] Example 2

[0129] like Figure 5 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0130] In this embodiment, the drive assembly 332 further includes a spring 35 disposed on the piston rod 3322;

[0131] When the airflow in the generator 1 pushes the piston rod 3322 to the left, the gas in the cylinder 3321 and the spring 35 simultaneously act as damping elements 333, playing a buffering role and further improving the protection effect.

[0132] Alternatively, depending on the specific application, the spring 35 can be used as a damping element 33. In this case, the spring 35 is mounted on the adjusting plate 331, providing a rightward pushing force to the adjusting plate 331. Initially, the seal 32 is located on the right side of the injection port 2 under the push of the spring 35, sealing the injection port 2. After the generator 1 is ignited and explodes, the resulting impact force is much greater than the pushing force of the spring 35. The impact force pushes the seal 32 to the left until the seal 32 moves to the left side of the injection port 2. Then, the airflow in the generator 1 is ejected outward through the injection port 2. After the airflow in the generator 1 is ejected, its internal pressure decreases, and the force on the seal 32 decreases. The spring 35 pushes the seal 32 to the right again, sealing the injection port 2.

[0133] Work steps

[0134] Step 1: Install the injection port 2 on the boiler body. In the initial state, the piston rod 3322 in the cylinder pushes the adjusting rod 331 to the right, so that the sealing element 32 moves to the right side of the injection port 2, separating the injection port 2 from the generator 1.

[0135] Step 2: Oxygen with a relatively high flow rate is supplied to generator 1 through gas supply pipe 1 41, and acetylene with a relatively low flow rate is supplied to generator 1 through gas supply pipe 2 42.

[0136] Step 3: During the gas delivery process, oxygen and acetylene are first mixed in the gas balance unit 43. By setting the gas balance unit 43 with a smaller pipe diameter, according to the Venturi effect, the fast-flowing oxygen will adsorb the acetylene flow, making it easier for acetylene to enter the generator 1.

[0137] During the gas transmission process, the sealing element 32 seals the generator 1, reducing the gas leakage from the generator 1, improving the gas utilization rate, and reducing the gas consumption generated during the gas transmission process.

[0138] Step 4: When the amount of mixed gas in generator 1 reaches the required level, start the cylinder to move the seal 32 to the left, and after opening a gap in the injection port 2, immediately start the igniter to ignite and deflagrate the mixed gas in generator 1.

[0139] Step 5: After the gas inside generator 1 explodes, the resulting impact force pushes the seal 32 to the left, which helps to accelerate the movement of the seal 32.

[0140] Step 6: After the seal 32 moves to the left side of the injection port 2, the high-speed airflow in the generator 1 is ejected outward through the injection port 2 to clean the furnace body by blowing away soot.

[0141] Step 7: After one deflagration ends, the cylinder pushes the adjusting rod 331 and the seal 32 to the right to reset, resealing the generator 1;

[0142] Step 8: Repeat steps 1 to 7 to perform the soot blowing work in a cyclical manner.

[0143] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
