Description

Technical Field

[0001] This invention relates to the field of gas combustion equipment technology, specifically to a device and application method for enhancing the combustion efficiency of diesel pile hammer gas. Background Technology

[0002] As a core construction machine in pile foundation engineering, the diesel pile hammer's working principle mainly relies on the compression ignition and detonation of diesel fuel within the cylinder to generate a tremendous downward mechanical impact force. In actual high-intensity, continuous pile driving operations, the completeness of combustion of the internal combustion gases in the diesel pile hammer directly determines the equipment's single-strike efficiency, work stability, and exhaust emission standards.

[0003] Traditional diesel piling hammers mostly use natural aspiration or simple forced air intake during the intake phase, with the air entering the combustion chamber typically at ambient temperature and pressure. Due to the low initial intake air density and lack of preheating, the mixing efficiency of fuel atomization particles and oxygen molecules, as well as the efficiency of thermal activation, are limited. Few integrated technologies in the industry can efficiently and non-interferingly recover this waste heat and airflow energy from the exhaust gas and directly feed it back into the intake combustion process. While some existing technologies attempt to add external air booster or heating equipment, these devices often require independent high-power external power supplies or additional power sources, resulting in a bulky overall equipment structure and significantly increased energy consumption. More importantly, external booster systems struggle to achieve natural mechanical synchronization with the high-frequency exhaust rhythm of the piling hammer itself, easily leading to airflow interference, turbulent oscillations, and air supply lag in the fluid pipeline.

[0008] Preferably, the transfer suction mechanism includes a suction pump head, which is fixed on a fixed frame and close to the output end of the heat exchange frame. An air output pipe is fixed to the output end of the suction pump head, and an air inlet bend is fixed to the input end of the suction pump head and connected to the output end of the heat exchange tube.

[0009] Preferably, the booster output mechanism includes a booster volute, which is fixed on a fixed frame and close to the output direction of the suction pump head. An output turbine is mounted on the input end of the booster volute, and the output turbine is connected to the output end of the air output pipe to receive the heated air output from the air output pipe.

[0013] Preferably, the synchronous suction tube is connected to the bottom surface of the parallel input tube, and a particle detection element is fixed at the output end of the synchronous suction tube.

[0014] Preferably, an application method for a diesel pile hammer combustion completion enhancement device includes the following steps: S1.

The exhaust gas conducts heat energy to the air inside the tube, completing the exhaust gas cooling and air preheating. S2. The cooled exhaust gas is discharged into the conversion vortex shell, which strongly impacts the conversion impeller and causes it to rotate at high speed, converting the fluid kinetic energy into mechanical shaft work.

[0015] This invention provides a device and application method for enhancing the combustion completeness of diesel pile hammer fuel. It has the following beneficial effects: 1. This invention achieves efficient recovery of waste heat from exhaust gas and preheating of pressurized air through the synchronous cooperation of the intake heat exchange mechanism and the transfer suction mechanism. In actual operation, high-temperature exhaust gas and room-temperature cold air flow separately on the inner and outer walls of the heat exchange frame and heat exchange tube. The two are in a state of absolute isolation in physical space, ensuring that the two fluid media do not mix or interfere with each other when carrying out high-intensity heat exchange. This synchronous suction and heat exchange action not only effectively reduces the final emission temperature of exhaust gas, but also reduces the heat load of subsequent pipelines.

[0016] 2. This invention utilizes the residual fluid kinetic energy during exhaust gas emission as the direct driving force for air pressurization, exhibiting extremely high mechanical transmission synchronization. The cooled exhaust gas impacts the conversion impeller of the wind-driven output mechanism at the optimal angle. Because the conversion impeller and the output turbine of the pressurization output mechanism adopt a mechanically rigid coaxial locking structure, the fluid dynamic pressure of the exhaust gas is instantly converted into mechanical shaft work that drives the turbine to rotate at high speed.

Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0020] Please see the appendix Figure 1 - Appendix Figure 2This invention provides a diesel pile hammer combustion completion enhancement device and application method, including: a fixed frame 1 for fixing the structure of the diesel pile hammer combustion completion enhancement device; and a control instrument 2 located on the fixed frame 1 for controlling and displaying the device's operating status. Please see the appendix Figure 1 -Appendix Figure 4 The intake heat exchange mechanism 3 is located on the fixed frame 1 and is used to draw in the exhaust gas generated by combustion and exchange heat simultaneously to heat the pressurized air. The intake heat exchange mechanism 3 is mounted on the fixed frame 1. Please see the appendix Figure 3 -Appendix Figure 4 The intake heat exchange mechanism 3 includes a heat exchange frame 31, which is fixed to the fixed frame 1 and arranged laterally. An exhaust gas inlet pipe 32 is fixed to the front side of the heat exchange frame 31, and the inlet end of the exhaust gas inlet pipe 32 is equipped with a pumping structure that can draw in the exhaust gas generated by combustion. Heat exchange tubes 34 are fixed to the output end face on the other side of the heat exchange frame 31, and are embedded side-by-side inside the heat exchange frame 31. An air inlet pipe 35 is fixed to the inlet end of the heat exchange tubes 34 extending outside the heat exchange frame 31. The exhaust gas inlet pipe 32 utilizes the impeller displacement action of the pumping structure at the inlet end to generate a fluid negative pressure, forcibly drawing in the high-temperature exhaust gas and guiding it into the inner cavity of the heat exchange frame 31. The high-temperature exhaust gas flow field filling the heat exchange frame 31 continuously surrounds the outer wall of the heat exchange tubes 34. Simultaneously, the air inlet pipe 35 guides ambient temperature air from outside into the interior of the heat exchange tubes 34. When the waste gas flows through the outer wall of the heat exchange tube 34, the high-temperature heat energy penetrates the metal tube wall of the heat exchange tube 34 and is conducted inward, causing the cold air flowing inside the heat exchange tube 34 to absorb a large amount of heat and rise in temperature, thereby completing the fluid heat exchange operation.

[0021] Please see the appendix Figure 1 -Appendix Figure 6 The transfer suction mechanism 4 is located on the fixed frame 1. It works with the heat exchange frame 31 and the heat exchange tube 34 to form the suction force of external pressurized air and to transfer and transport it. The transfer suction mechanism 4 is set on the fixed frame 1 and is positioned in the output direction of the suction heat exchange mechanism 3. Please see the appendix Figure 4 -Appendix Figure 6The transfer suction mechanism 4 includes a suction pump head 41, which is fixed on the fixed frame 1 and located near the output end of the heat exchange frame 31. An air output pipe 42 is fixed to the output end of the suction pump head 41, while an air inlet bend 43 is fixed to the input end of the suction pump head 41 and connected to the output end of the heat exchange tube 34. The rotor inside the suction pump head 41 rotates at high speed, generating a strong suction negative pressure at the input end. This negative pressure is conducted in reverse through the air inlet bend 43, precisely acting on the inside of the heat exchange tube 34, forcibly pulling the heated air out of the heat exchange tube 34 and completely flowing into the suction pump head 41 along the air inlet bend 43. The suction pump head 41 applies mechanical thrust to the inhaled high-temperature air, squeezing and pushing it into the air output pipe 42. The air output pipe 42 restricts the airflow diffusion, precisely guiding the high-temperature air with an initial flow velocity to the subsequent pressurization section.

[0022] Please see the appendix Figure 6 -Appendix Figure 8 The booster output mechanism 5 is located on the fixed frame 1. It works with the suction pump head 41 and the air inlet bend 43 to generate the booster driving force of the external air and to spray the gas end of the diesel pile hammer. The booster output mechanism 5 is mounted on the fixed frame 1 and is close to the output end of the transfer suction mechanism 4. Please see the appendix Figure 6 -Appendix Figure 8 The booster output mechanism 5 includes a booster vortex housing 51, which is fixed to the fixed frame 1 and located near the output direction of the suction pump head 41. An output turbine 52 is mounted at the input end of the booster vortex housing 51 and is connected to the output end of the air output pipe 42 to receive heated air from the air output pipe 42. An inlet duct 53 is rotatably embedded within the booster vortex housing 51. The output turbine 52 receives external rotational driving force and rotates at high speed at the input end of the booster vortex housing 51. After the high-temperature air delivered by the air output pipe 42 rushes in, it is forcefully captured by the blades of the output turbine 52 and thrown radially at high speed into the booster vortex housing 51. The gradually expanding flow channel of the booster vortex housing 51 forces the high-speed airflow to decelerate and diffuse, transforming it into high-density compressed hot air. This high-pressure airflow then rushes into the inlet duct 53, which rotates within the booster vortex housing 51 to dynamically adjust the injection angle, precisely pushing the high-pressure airflow into the pile hammer.

[0023] Please see the appendix Figure 7 -Appendix Figure 9 The pneumatic output mechanism 6 is located on the booster output mechanism 5. It works with the output bend 33, the booster volute 51 and the output turbine 52 to form the rotational transmission force for exhaust gas delivery. The pneumatic output mechanism 6 is mounted on the booster output mechanism 5. Please see the appendix Figure 7 -Appendix Figure 9The pneumatic output mechanism 6 includes a conversion vortex housing 61, which is fixed inside the booster vortex housing 51. A conversion impeller 62 is embedded inside the conversion vortex housing 61 and its output end is fixed to the output end of the output turbine 52. The conversion vortex housing 61 has two ports: the bottom port is connected to the output end of the output bend 33 to receive the heat-exchanged exhaust gas, while the rear port is fixed with an end filter 63. The heat-exchanged exhaust gas is guided along the curvature of the output bend 33 and enters the bottom port of the conversion vortex housing 61 at a specific angle. The volute-shaped flow channel of the conversion vortex housing 61 spatially compresses and accelerates the exhaust gas, causing it to impact the blades of the conversion impeller 62 at high speed. The conversion impeller 62 rotates at high speed around its axis under the pressure of the fluid, converting the kinetic energy of the exhaust gas into mechanical shaft work. The exhaust gas, having lost its kinetic energy, flows out from the rear of the conversion vortex housing 61 and enters the end filter 63. The internal material of the end filter 63 physically intercepts and adsorbs residual particles in the exhaust gas.

[0024] Please see the appendix Figure 7 -Appendix Figure 10 The synchronous detection mechanism 7 is located on the fixed frame 1 and works with the heat exchange frame 31 and the suction pump head 41 to detect the particle size of the pressurized air in real time. The synchronous detection mechanism 7 is mounted on the fixed frame 1. Please see the appendix Figure 10 The synchronous detection mechanism 7 includes an intermittent suction pump 71 and a synchronous suction pipe 76. The intermittent suction pump 71 is fixed on the fixed frame 1, and a conversion multi-port pipe 72 is fixed to the output end of the intermittent suction pump 71. A suction input pipe 73 is fixed to one side of the conversion multi-port pipe 72, and a parallel input pipe 74 is fixed to the other end of the suction input pipe 73. The input end of the parallel input pipe 74 is connected to the side of the booster volute 51. The intermittent suction pump 71 performs periodic operation, and its suction negative pressure is transmitted through the conversion multi-port pipe 72 and the suction input pipe 73 to the interior of the parallel input pipe 74. Guided by negative pressure, the parallel input pipe 74 tears open a sampling notch from the side wall of the pressurized vortex shell 51 to extract a trace amount of air sample under high pressure. After the extracted air sample enters the parallel input pipe 74, it is split. A portion of the gas leaves the main path and is guided by its own pressure gradient and gravity to descend into the synchronous suction pipe 76, which then directionally transports it to the subsequent detection stage. Please see the appendix Figure 10The other end of the switching multi-port tube 72 is fixed with an output capillary tube 75, and the end of the output capillary tube 75 is connected to the inner side of the suction pump head 41. The switching multi-port tube 72 serves as a hub for the convergence of multiple airflows. In its inner cavity, it receives the remaining undetected gas sample delivered by the suction input tube 73. The chamber wall of the switching multi-port tube 72 initially buffers and constricts the incoming scattered airflow. Then, under the pressure difference thrust provided by the continuous operation of the intermittent suction pump, the switching multi-port tube 72 forces the converged gas into the output capillary tube 75 fixed at its other end. The output capillary tube 75 restricts the lateral expansion of the airflow, smoothly guides the gas, and reinjects it into the low-pressure area on the inner side of the suction pump head 41. Please see the appendix Figure 10 A synchronous suction tube 76 is connected to the bottom surface of a parallel input tube 74, and a particle detection element 77 is fixed to the output end of the synchronous suction tube 76. The synchronous suction tube 76 directly and losslessly introduces the sample gas intercepted by the shunt into the detection chamber of the particle detection element 77. When the sample gas flows through the detection area of ​​the particle detection element 77, the optical module inside the particle detection element 77 emits a detection beam that penetrates the gas flow. Suspended foreign objects entrained in the gas physically block and scatter the detection beam. The particle detection element 77 captures this optical variation phenomenon, converts the optical signal into an electrical signal and analyzes it, thereby outputting the particle size distribution data of the currently pressurized air for monitoring.

[0025] Based on the above technical solution, this embodiment of the invention also provides a working principle for the application of a diesel pile hammer combustion completion enhancement device, including the following: The overall working principle of the equipment follows a rigorous logic of thermodynamic energy recovery, fluid dynamics pressurization and conduction, and dynamic airflow monitoring. By controlling the instrument 2 to input operating commands and continuously feeding back various operating parameters, it coordinates the orderly linkage of various mechanical mechanisms. When the pile hammer combustion component completes its initial ignition and work, it will generate combustion exhaust gas with extremely high temperature and initial kinetic energy. The pumping structure configured at the input end of the exhaust gas input pipe 32 will then start operating. The high-speed rotation of the impeller inside the pumping structure will generate a violent cutting and extrusion effect on the surrounding flow field, thereby establishing a strong negative pressure at the input port. In the suction area, this powerful negative pressure suction force acts directly on the exhaust end of the combustion chamber, forcibly drawing in and extracting the high-temperature, high-pressure exhaust gas. The fluid is then initially stabilized and guided along the inner wall cavity of the exhaust gas inlet pipe 32. Subsequently, this high-temperature fluid is fully and without loss injected into the internal cavity of the heat exchange frame 31. After entering the heat exchange frame 31, the high-temperature exhaust gas rapidly diffuses and completely fills the entire inner cavity, forming a covering heat flow field. The heat exchange tubes 34 are arranged in a parallel array within this heat flow field. When the high-temperature exhaust gas flows past the outer wall surface of the heat exchange tubes 34, a strong convective heat transfer reaction occurs between the fluid and the metal tube wall. The enormous heat energy contained in the exhaust gas rapidly penetrates the tube wall of the heat exchange tubes 34 and is conducted into the tube interior. Simultaneously, the transfer suction mechanism... 4. The media transfer operation begins synchronously. The motor inside the suction pump head 41 drives the rotor to perform a rotating suction action, generating a continuous vacuum negative pressure at its input end. This continuous fluid pull propagates in the reverse direction along the air inlet bend 43, directly acting on the output end of the heat exchange tube 34, thereby forming an extremely strong guiding negative pressure inside the heat exchange tube 34. Under the forced traction of the internal negative pressure, ambient temperature mixed air from the external environment is continuously drawn in through the air inlet pipe 35. The ambient temperature air flows into the air inlet pipe 35 and is evenly distributed into the interior of each parallel heat exchange tube 34. When the cold air flows forward in the inner cavity of the heat exchange tube 34, the high-temperature heat continuously conducted into the tube wall causes high-intensity thermal excitation of the air molecules. After absorbing heat energy, the thermal motion intensifies, and the fluid temperature exhibits a steep upward curve, achieving a rapid leap from room temperature to a high temperature state. As cold air continuously sweeps across the inner wall of the pipe, carrying away heat, the high-temperature exhaust gas inside and outside the heat exchange frame 31 gradually loses heat energy, and its temperature and volume shrink and degrade, completing a complete cross-medium heat transfer operation. This heat transfer not only effectively reduces the exhaust temperature of the exhaust gas, but also endows the input air with initial thermodynamic potential. The fully heated pressurized pre-air, under the continuous traction of the suction pump head 41, quickly detaches from the end of the heat exchange tube 34 and is completely sucked into the suction pump head 41 along the pipe path of the air inlet bend 43. The internal rotor of the suction pump head 41 imparts kinetic energy to this high-temperature airflow.The air is forced into the air output pipe 42 in a more stable state with a certain initial flow velocity. The air output pipe 42 acts as a fluid bridge, precisely guiding this high-heat-energy airflow to the input end of the pressurization output mechanism 5, providing sufficient and optimal gas feedstock for its subsequent pressurization operation. During this period, the cooled exhaust gas, which has already released heat in the heat exchange frame 31, still retains considerable fluid kinetic energy and flow inertia. This exhaust gas flow is gathered by the structure at the rear end of the heat exchange frame 31 and discharged into the output bend 33. The specific curvature design of the output bend 33 guides the exhaust gas fluid to undergo vector deflection, allowing it to directly enter the conversion vortex 61 connected to the bottom port of the pneumatic output mechanism 6 at the optimal impact angle, and enter the conversion... The exhaust gas fluid in the vortex casing 61 is compressed and accelerated by the volute channel inside the vortex casing, resulting in a secondary increase in velocity. It then violently impacts the windward surface of the impeller blades 62 like a high-pressure water jet. The fluid dynamic pressure and impact force of the exhaust gas are applied without reservation to the blade structure of the impeller 62, forcing it to overcome mechanical friction and begin high-frequency rotation around its central axis. During this process, the original fluid dynamic kinetic energy of the exhaust gas is completely converted into the mechanical shaft work of the impeller 62's rotation, achieving a second leap in energy form. The weakened exhaust gas, having lost all usable kinetic energy and pressure, flows out along the blade trails, reaching the rear port of the vortex casing 61, and irreversibly enters the end filter 63. The end filter 63... The interception net and adsorption substrate intercept and chemically adsorb the tiny carbon particles remaining in the exhaust gas, ensuring that the final gas emitted is pure and discharged from the system, thus preventing secondary pollution to the external environment. Because there is a direct, rigid mechanical transmission connection between the pneumatic output mechanism 6 and the booster output mechanism 5, the output end of the converter impeller 62 and the output end of the output turbine 52 maintain absolute axial locking. Therefore, any tiny rotational torque generated by the converter impeller 62 under the impact of the exhaust gas will be synchronously transmitted to the output turbine 52 without delay or slippage. This rigid transmission allows the output turbine 52 to rotate at the same high speed as the converter impeller 62 inside the booster volute 51. At this time, the high-temperature mixed air delivered by the air output pipe 42 is precisely... Upon reaching the input end of the output turbine 52, the high-speed rotating output turbine 52 acts like a powerful centrifugal compressor. Its sharp blade leading edges violently cut and capture the incoming high-temperature air. Air molecules, after being drawn into the blade channel, are subjected to extremely strong centrifugal force and are flung outward at high speed along the radial direction of the blades. During this high-speed ejection process, the absolute velocity of the airflow increases dramatically. When this high-speed, high-temperature airflow, carrying enormous kinetic energy, detaches from the outer edge of the blades of the output turbine 52 and rushes into the ever-expanding diffuser cavity inside the pressurizing vortex casing 51, the airflow cross-sectional area rapidly increases, causing the fluid velocity to drop sharply. According to Bernoulli's principle of fluid dynamics, the kinetic energy of the suddenly reduced airflow is instantly converted into extremely high hydrostatic pressure. After this centrifugal diffusion process…The originally atmospheric pressure, high-temperature air is completely compressed and reshaped, transforming into oxygen-rich compressed air with extremely high density, high pressure, and high thermal energy. This high-quality combustion-supporting gas is then forcibly forced into the inlet air duct 53. Accompanied by the surging airflow, the inlet air duct 53 rotates and embeds itself within the pressurization vortex housing 51. This dynamic rotation effectively dissipates the turbulent oscillations caused by the high-pressure airflow. Based on the operating requirements of the pile driver's combustion chamber, the high-pressure hot air is precisely transmitted to the combustion components of the diesel pile driver's fuel system with the most perfect injection angle and force. Once the high-density, preheated oxygen molecules come into contact with the diesel atomized particles in the combustion chamber, they can trigger a violent, complete, and thorough deflagration reaction within a very short delay period. The explosive mechanical impact force significantly enhances the operational efficiency of the pile driver. Throughout the entire fluid transport cycle, during which air is continuously drawn in, heated, pressurized, and transported, the synchronous detection mechanism 7 continuously undertakes the task of rigorously monitoring the airflow quality. After receiving the pulse electrical signal from the control instrument 2, the intermittent suction pump 71 performs periodic start-stop suction actions. Each time it starts, the intermittent suction pump 71 generates an extremely small but highly penetrating negative pressure in the system. This small negative pressure is transmitted backward through the conversion multi-port pipe 72, passes through the suction input pipe 73, and is precisely delivered to the interior of the parallel input pipe 74. Since the input end of the parallel input pipe 74 is directly connected to the side wall of the pressurization volute 51, This tiny negative pressure will tear open a sampling gap in the boundary layer region of the high-pressure airflow. The mixed air inside the pressurized vortex 51, which is under high pressure, will be guided by this directional negative pressure to differentiate a very small portion of gas as a detection sample. This sample gas flows backward along the pressure gradient into the parallel input pipe 74. This sample gas accurately reflects the pressure, temperature, and purity of the air currently entering the combustion chamber. The sample gas flows along the parallel input pipe 74 and is guided to the synchronous suction pipe 76 at the fluid branch point. The synchronous suction pipe 76 directly and non-destructively introduces the sample gas into the detection chamber of the particle detection element 77. The optical scattering sensor or laser counting module inside the particle detection element 77 instantly emits a detection beam. As the sample gas stream penetrates, any tiny suspended particles, dust, or foreign matter in the gas will scatter and obscure the light beam. The detection element captures these optical changes and quickly converts them into electrical signals. After being analyzed by a complex algorithm of the internal microprocessor, extremely precise particle size distribution data and concentration indicators of the current pressurized air are obtained. These crucial data streams are transmitted back to the display panel of the control instrument 2 in real time, allowing operators to clearly monitor the air purification and combustion preparation status. To ensure that the sample gas used for detection is not arbitrarily discharged after optical irradiation and data extraction, which could lead to pressure loss in the entire pneumatic system or backflow of external gas, the sample gas is guided back after leaving the particle detection element 77.The continuous suction force generated by the intermittent suction pump 71 draws the remaining gas sample from the main suction input pipe 73 and the detected gas together into the cavity of the switching multi-port pipe 72. Subsequently, this gas is directed into the output capillary pipe 75, which serves as the system's return conduit, redirecting this gas flow and ultimately injecting it into the low-pressure area on the inner surface of the suction pump head 41.
