Abstract

This invention discloses a micro-liquid-containing gas flow disturbance and crushing system and method for combustion equipment. The system includes a water-containing medium supply unit, a micro-liquid-containing gas flow generation component, a disturbance and crushing component, and a connection end to the combustion equipment. The generation component contacts the gas with the water-containing medium and forms a confined liquid-containing gas flow through a liquid-volume constraint structure; the disturbance and crushing component causes the gas to undergo continuous secondary crushing to form an aerosol containing fine droplets or an enhanced gas-liquid composite phase, which is then output to the combustion equipment. It can be used for heat load suppression, knock margin compensation, or combustion organization optimization in combustion equipment.

Description

Technical Field

[0001] This invention relates to the fields of combustion equipment intake regulation, gas-liquid two-phase flow micro-crushing, and combustion condition optimization, and particularly to a micro-liquid-containing airflow disturbance crushing system and method for engines, burners, boilers, kilns, gas turbines, or generator sets.

[0002] More specifically, the present invention relates to a system and method for introducing water, water-alcohol mixture, emulsion or other water-containing medium into an airflow in a limited liquid volume manner, and continuously breaking up the entrained droplets through a downstream disturbance and breaking component to form an aerosol containing fine droplets or an enhanced gas-liquid composite phase, which is then fed into the air inlet side of a combustion device, the mixing section of a burner or the air passage of a combustion device. Background Technology

[0003] During the operation of combustion equipment such as engines, burners, boilers, and generator sets, problems may occur in the combustion chamber or high-temperature reaction zone, such as localized excessively high temperatures, concentrated heat load, insufficient knock margin, kinetic heat decay after prolonged high-load operation, deposit formation, or fluctuations in combustion organization. To address these conditions, existing technologies include solutions that introduce water, water-alcohol mixtures, steam, humid air, or other water-containing media into the air intake side of the combustion equipment, the air passage of the combustion equipment, or the mixing section of the burner.

[0004] Traditional water-injection or alcohol-injection systems typically employ a liquid pump, nozzles, solenoid valves, and control units to inject water or a water-alcohol mixture into the intake side or combustion zone. While this type of system can reduce intake temperature, suppress knocking, or regulate heat load under certain high-load conditions, it generally suffers from problems such as large liquid consumption, system complexity, demanding installation and calibration requirements, reliance on electronic control components, and nozzle clogging or injection inaccuracy. For aftermarket modifications, small engines, off-road equipment, or partial burner retrofits, the installation and maintenance costs of complex electronically controlled water-injection systems are high.

[0005] Other solutions employ containers, inlet pipes, outlet pipes, liquid sluice structures, liquid level observation structures, or liquid bubbling structures to generate water-containing air after the gas comes into contact with water or aqueous solutions, which is then introduced into the engine or combustion equipment. These solutions are structurally simpler, but they mostly focus on generating water-containing air, humidifying the gas flow, or creating a gas-liquid mixture. They lack effective control over the droplet size, liquid carryover amount, and downstream secondary abrasion degree before entering the combustion equipment. If the liquid entrainment is too large, large droplets may enter the intake side or combustion channel; if the liquid entrainment is too small, the heat load regulation effect is easily affected by operating conditions.

[0006] Existing technologies include solutions that use structures such as pipes, holes, grooves, perforations, spiral tubes, or gas-liquid mixing containers to allow airflow to contact or agitate liquids or water-containing gases. However, from an engineering perspective, combustion equipment does not simply require high-humidity air, nor does it need to achieve abstract gas treatment effects. Instead, it requires delivering water-containing media in the form of fine droplet aerosols or enhanced gas-liquid composite phases—which are easy to transport and suitable for the combustion environment—to the target area while maintaining a controllable amount of liquid consumption.

[0007] Therefore, a system solution is needed. This solution first forms a liquid-containing gas flow with limited liquid volume, and then continuously breaks up and homogenizes the entrained droplets in a secondary process through a downstream disturbance channel unit containing at least two disturbance sections. This is used to form a fine droplet-containing aerosol or an enhanced gas-liquid composite phase that can be fed into combustion equipment with a low liquid volume. Summary of the Invention

[0008] This invention aims to solve the following problems existing in the water-containing medium supply scheme of existing combustion equipment: 1) Conventional humidification, bubbling, or gas-liquid mixing structures mainly produce water-containing air, making it difficult to control the amount of liquid carried and the degree of droplet refinement before entering the combustion equipment; 2) Traditional water spray or wine spray systems typically consume a large amount of liquid and rely on liquid pumps, nozzles, electronic control units, or complex adjustments; 3) A single disturbance structure is insufficient to break up entrained droplets, which can easily lead to the carry-out of large droplets, fluctuations in droplet size distribution, or differences in output under different operating conditions. 4) Simply adding orifice plates, reduced diameter holes, spiral parts or venturi parts can usually only create one disturbance, making it difficult for the droplet stretching, rupture, wall shearing, orifice dispersion or swirling disturbance formed in the previous disturbance state to continue to be transmitted to the next disturbance section. 5) When retrofitting, main engine manufacturers or burner manufacturers can easily replace single disturbance components, single orifice plates, single venturis, or single spiral components at low cost, lacking system protection for the entire chain of restricted liquid volume liquid-containing gas flow + continuous secondary crushing path + combustion equipment output.

[0009] Therefore, the present invention provides a micro-liquid-containing gas flow disturbance and crushing system and method for combustion equipment. The aqueous medium first enters the gas flow in a restricted flow manner to form a liquid-containing gas flow, and then undergoes continuous secondary crushing through a disturbance channel unit containing at least two disturbance sections, outputting an aerosol containing fine droplets or an enhanced gas-liquid composite phase.

[0010] To achieve the above objectives, the present invention provides a micro-liquid-containing gas flow disturbance and crushing system for combustion equipment. Specifically, it includes a water-containing medium supply unit, a micro-liquid-containing gas flow generation component, a disturbance and crushing component, and a combustion equipment connection end.

[0011] Specifically, the aqueous medium supply unit is used to contain or supply water, water-alcohol mixture, emulsion or other aqueous media.

[0012] Specifically, the micro-liquid gas flow generating component is used to enable the gas to form a liquid-containing gas flow carrying droplets by contacting the water-containing medium provided by the water-containing medium supply unit under negative pressure suction, ejection, pumping or pressure driving in one or more ways, such as liquid surface contact, liquid film contact, capillary wetting contact, porous liquid seepage contact or micro-liquid supply contact.

[0013] Specifically, the micro-volume liquid-containing gas flow generation component has a liquid volume constraint structure. The liquid volume constraint structure is used to make the fluid entering the disturbance and breakup component a restricted liquid-containing gas flow with entrained droplets through one or more of the following methods: liquid level height, gas-liquid contact area, gas flow channel cross section, gas-liquid separation space, deflection path, inertial separation, reflux channel, capillary liquid supply or micropore liquid supply.

[0014] Specifically, the disturbance and breakup assembly is located downstream of the trace liquid-containing gas flow generation assembly. The disturbance and breakup assembly includes at least one disturbance channel unit, within which at least two disturbance sections are arranged along the liquid-containing gas flow direction. The at least two disturbance sections are connected in series within the same disturbance channel unit along the liquid-containing gas flow direction. Adjacent disturbance sections can be directly connected, or they can be connected through an inter-section transition cavity, an inter-section contraction channel, or an inter-section expansion channel.

[0015] Specifically, the at least two disturbance sections form a continuous secondary breaking path along the flow direction of the liquid-containing gas flow, so that the limited liquid volume liquid-containing gas flow enters the subsequent disturbance section under the state of droplet stretching, rupture, wall shearing, hole dispersion, swirling disturbance or pressure drop pulsation formed in the previous disturbance section to continue breaking and homogenizing, so as to output an aerosol containing micro-droplets or an enhanced gas-liquid composite phase.

[0016] Specifically, the combustion equipment connection end is connected to the outlet of the disturbance and breakup component, and is used to deliver the aerosol or enhanced gas-liquid composite phase into the engine intake side, the burner mixing section, the boiler combustion air duct, the primary air duct, the secondary air duct, or the combustion equipment air duct.

[0017] Specifically, the disturbance and breakup assembly is not simply a single disturbance element placed at the liquid-containing gas flow output end, but rather at least two interconnected disturbance sections are arranged within the same disturbance channel unit along the liquid-containing gas flow direction. After the preceding disturbance section causes stretching, rupture, wall shearing, orifice dispersion, swirling disturbance, or pressure drop pulsation of the entrained droplets, the restricted liquid-containing gas flow continues to enter the following disturbance section, thus perpetuating the previous disturbance state and further breaking up and homogenizing it. Therefore, this invention differs from gas-liquid contact devices that only form a humidified airflow, and also from nozzle-type systems that directly inject liquid into combustion equipment.

[0018] Specifically, in some embodiments, the micro-liquid-containing gas flow generating component includes one or more of the following: liquid surface swirling channel, liquid film swirling channel, capillary wetting element, fiber wetting element, porous liquid permeation element, microporous liquid supply element, low-pressure ejector mixing element, or droplet pre-entraining element.

[0019] Specifically, in some embodiments, the liquid volume constraint structure includes one or more of the following: a liquid-blocking wall, a flow-deflecting baffle, an inertial separation chamber, a liquid return tank, a droplet impact and fall surface, a labyrinth fall channel, a baffle to prevent large droplets from being carried out, a liquid level limiting structure, or a gas-liquid separation space.

[0020] Specifically, in some embodiments, the disturbance section includes one or more of the following: a narrow-diameter orifice section, an expanded cavity section, an eccentric cavity section, a local throat section, a spiral disturbance section, a misaligned orifice plate section, a collision wall section, a baffle section, a labyrinth channel section, a venturi section, a swirling pressure drop section, a tangential inlet cavity section, or a porous dispersion section.

[0021] Specifically, in some embodiments, the porous dispersion section is a localized perforation, dispersion, or wall shearing structure disposed within the disturbance channel unit, and it can be used as a local structural segment among multiple disturbance sections. The porous dispersion section in this application is not equivalent to a scheme using a honeycomb carrier, DPF carrier, or integral porous filter core as the main disturbance and breakup component.

[0022] Specifically, in some embodiments, the disturbance breaking component includes at least two disturbance channel units arranged in parallel, with the inlet of each disturbance channel unit connected to the inlet collection cavity and the outlet of each disturbance channel unit connected to the outlet collection cavity; each disturbance channel unit is provided with at least two disturbance sections connected in series along the flow direction to form a combined structure of series disturbance within the channel and parallel flow amplification between channels.

[0023] Specifically, in some embodiments, multiple disturbance sections within at least one disturbance channel unit are heterogeneous series structures; and / or, the disturbance section types, number of disturbance sections, arrangement order of disturbance sections, channel hydraulic diameter, local pressure drop structure, or outlet angle are different between at least two disturbance channel units, so that the droplet breakup state, pressure pulsation spectrum, velocity pulsation spectrum, or vortex structure output by different disturbance channel units are different.

[0024] Specifically, in some embodiments, a multi-channel series-parallel disturbance topology can be formed within a single disturbance breaking component. The disturbance breaking component includes at least two parallel disturbance channel units, each containing at least two disturbance sections along the liquid-containing gas flow direction. Multiple disturbance sections within the same parallel disturbance channel unit can be isomorphically connected in series or heteromorphically connected in series. Different parallel disturbance channel units can employ the same or different disturbance section types, numbers, arrangement order, channel hydraulic diameters, local pressure drop structures, or outlet angles. Thus, a combined topology of series disturbance within the channel and parallel flow amplification between channels is formed within a single disturbance breaking component, ensuring that the limited liquid-containing gas flow undergoes continuous secondary breaking within each parallel branch, and converges and homogenizes in the outlet collecting chamber.

[0025] Specifically, in some embodiments, the disturbance and breakup assembly may include at least two disturbance and breakup assemblies connected in series along the flow direction of the liquid-containing gas stream. Each disturbance and breakup assembly is a parallel disturbance module, including an inlet collecting chamber, an outlet collecting chamber, and at least two disturbance channel units located between the inlet collecting chamber and the outlet collecting chamber. Each disturbance channel unit is provided with at least two disturbance sections connected in series along the flow direction. Adjacent disturbance and breakup assemblies that are parallel disturbance modules can be directly connected by the outlet collecting chamber of the preceding disturbance and breakup assembly to the inlet collecting chamber of the following disturbance and breakup assembly, or they can be connected through a transition channel, a contraction channel, or an expansion channel. This structure allows the liquid-containing gas stream output from the preceding disturbance and breakup assembly to continue entering the following disturbance and breakup assembly for further breakup and homogenization. This structure is suitable for operating conditions with large flow rates or long processing paths, and does not change the system chain where the limited liquid volume liquid-containing gas stream enters the disturbance and breakup assembly and is then output to the combustion equipment.

[0026] Specifically, in some embodiments, the disturbance and breakage component can be configured as a replaceable core component or as a non-removable integrated welded, glued, hot-melted, press-fitted, or integrally molded component. A replaceable structure facilitates maintenance and adaptation to different combustion equipment, while a non-removable structure can be used in scenarios requiring high consistency in sealing, vibration resistance, or mass production. Both are choices for specific implementation methods and are not necessary limitations for the system described in claim 1.

[0027] In some embodiments, at least one disturbance channel unit includes a swirling guide section and a swirling pressure drop section connected in sequence. The swirling guide section is used to convert the axial momentum of the liquid-containing gas flow into a rotating flow with a tangential velocity component, and the swirling pressure drop section is used to receive the rotating flow and form a radial pressure gradient, a local pressure drop zone, and a pressure pulsation zone to promote secondary breakup of entrained droplets and refinement of the gas-liquid interface.

[0028] Specifically, in some embodiments, the disturbance breaking component is a replaceable core component. The replaceable core component is installed in the housing by means of snap-fit, thread, flange, plug-in seal, compression seal, end cap compression, or clamp connection. It can be replaced with disturbance breaking components with different disturbance section types, different numbers of disturbance sections, different numbers of parallel channels, or different channel hydraulic diameters without replacing the water-containing medium supply part and / or the housing.

[0029] The present invention also provides a method for disrupting and breaking up a small amount of liquid-containing gas flow in a combustion device. The method includes: S1. Under negative pressure suction, ejection, pumping or pressure driving, the gas is made to form a liquid-containing gas flow with droplets by one or more of the following methods: liquid surface contact, liquid film contact, capillary wetting contact, porous liquid seepage contact or micro-liquid supply contact. S2. By using one or more of the following methods, such as liquid level height, gas-liquid contact area, gas flow channel cross section, gas-liquid separation space, baffle path, inertial separation, reflux channel, capillary liquid supply or micropore liquid supply, the fluid entering the disturbance and crushing component is a limited liquid volume liquid-containing gas flow with entrained droplets. S3. Allow the restricted liquid-containing gas flow to enter the disturbance crushing component; S4, and in the continuous secondary fragmentation path formed by at least two disturbance nodes, droplet stretching, rupture, wall shearing, hole dispersion, swirling disturbance, baffle collision, pressure drop pulsation and / or homogenization treatment are sequentially performed to form an aerosol containing micro-droplets or an enhanced gas-liquid composite phase. S5. The aerosol or enhanced gas-liquid composite phase is delivered into the engine intake side, the burner mixing section, the boiler combustion air duct, the primary air duct, the secondary air duct, or the combustion equipment air duct.

[0030] It has the following beneficial effects: (1) By limiting the amount of liquid carried by the liquid volume constraint structure, the risk of large droplets entering the combustion equipment can be reduced.

[0031] (2) After the liquid-containing gas flow with limited liquid volume enters the disturbance crushing component, it is beneficial to be sheared, dispersed and homogenized again in the continuous secondary crushing path formed by at least two disturbance sections.

[0032] (3) The implementation methods of isomorphic or heteromorphic series connection, parallel connection of multiple disturbance channel units, and series connection of multiple disturbance breaking components can be used to match different flow rates and installation spaces.

[0033] (4) The system can be connected to different combustion equipment by means of negative pressure suction, ejection, pumping or pressure drive.

[0034] (5) The output aerosol or enhanced gas-liquid composite phase can be used for heat load suppression, knock margin compensation, heat decay suppression, deposition tendency reduction or combustion organization optimization; the specific degree of effect is affected by fuel type, temperature field, residence time, excess air coefficient, aerosol particle size distribution and combustion equipment operating conditions.

[0035] Terminology definition Micro-liquid-containing gas flow: refers to a gas-liquid-carrying flow formed by gas, under negative pressure suction, ejection, pumping, or pressure driving, coming into contact with a water-containing medium through liquid surface contact, liquid film contact, capillary wetting contact, porous seepage contact, or micro-liquid supply contact, and carrying a small amount of liquid droplets. It is different from simple high-humidity air, and also different from the large-volume liquid mist formed by direct injection from a high-pressure nozzle.

[0036] Limited liquid volume: This refers to the amount of liquid phase carried into the agitation and crushing component, limited to a range suitable for downstream agitation and crushing and combustion equipment, through structural methods such as liquid level height, gas-liquid contact area, channel cross-section, gas-liquid separation space, baffle path, inertial separation, reflux channel, capillary liquid supply, or micropore liquid supply. The limited liquid volume is not required to be a fixed value and can vary with the type of combustion equipment, inlet flow rate, negative pressure, properties of the water-containing medium, and the agitation structure.

[0037] Liquid volume constraint structures refer to structures or combinations of structures used to limit the amount of liquid carried in a liquid-containing gas flow. These include, but are not limited to, height-limiting liquid surface structures, gas-liquid separation spaces, baffle paths, inertial separation chambers, liquid-blocking walls, droplet impact return surfaces, liquid return troughs, capillary liquid supply structures, or microporous liquid supply structures. The purpose of liquid volume constraint structures is not simply to increase humidity, but to ensure that the fluid entering the agitated breakup components is in a liquid-containing gas flow state with a limited volume.

[0038] Disturbance section: refers to a structural segment installed within a disturbance channel unit that can induce local shearing, collision, swirling, jetting, deflection, pressure drop pulsation, wall flow dispersion, droplet stretching, liquid film rupture, or homogenization in the liquid-containing gas flow. Disturbance sections can be narrow-diameter orifices, expansion cavities, eccentric cavities, local throats, helical disturbance components, misaligned orifice plates, collision walls, deflection structures, labyrinth channels, venturi sections, swirling pressure drop structures, tangential inlet chambers, or porous dispersion structures.

[0039] Disturbance channel unit: refers to a flow channel unit through which liquid-containing gas flows, and has at least two disturbance sections arranged along the flow direction inside. Disturbance channel units can be straight, curved, spiral, annular, plate-type stacked, or tube bundle type.

[0040] Parallel disturbance module: In this application, it refers to a module that can be connected by... Figure 7 The modular structure formed by the disturbance breaking component shown includes an inlet collecting chamber, an outlet collecting chamber, and at least two disturbance channel units located between the two, with at least two disturbance sections connected in series along the flow direction in each disturbance channel unit.

[0041] Series-parallel disturbance topology: refers to the structural relationship in which disturbance channels within a disturbance breaking component are connected in series and in parallel to amplify the flow. In some implementations, multiple disturbance breaking components that serve as parallel disturbance modules can also be connected in series along the direction of liquid-containing gas flow to form a continuous secondary / multiple breaking path.

[0042] Continuous secondary disruption path: This refers to a flow path where the liquid-containing gas with limited flow rate passes sequentially through at least two disturbance sections connected in series along the flow direction within the same disturbance channel unit. The liquid-containing gas flow output from the previous disturbance section is not the final output but continues into the next disturbance section before being directly fed into the combustion equipment, where it undergoes further disturbance disruption and homogenization. The continuous secondary disruption path includes paths where adjacent disturbance sections are directly connected, as well as paths where adjacent disturbance sections are connected through inter-discussion section transition chambers, inter-discussion contraction channels, or inter-discussion expansion channels.

[0043] Homogeneous series connection: refers to the repeated arrangement of multiple disturbance sections within the same disturbance channel unit using the same or basically the same structural type, such as multiple reduced diameter orifice sections connected in series, or multiple spiral disturbance sections connected in series.

[0044] Heterogeneous series connection: refers to the combination of multiple disturbance sections with different structural types within the same disturbance channel unit, such as spiral disturbance section, narrow-diameter orifice section, and expansion cavity section arranged in sequence, or Venturi section, collision wall section, and baffle section arranged in sequence.

[0045] Enhanced gas-liquid composite phase: refers to the gas-liquid mixed state formed after a limited liquid volume of liquid-containing gas flow is processed by a disturbance and breakup component, resulting in reduced droplet size, increased gas-liquid interface area, and enhanced droplet dispersion.

[0046] Aerosols are dispersion systems formed by gas phase carrying fine droplets. The term "aerosol" in this application is not limited to a specific particle size range, nor does it require a specific holding time or a specific droplet concentration.

[0047] The porous dispersion section refers to a localized perforation, dispersion, or wall shearing structure disposed within the disturbance channel unit, which can be used as a local structural segment among multiple disturbance sections. The porous dispersion section in this application is not equivalent to a scheme using a honeycomb carrier, DPF carrier, or integral porous filter core as the main disturbance and breakup component. Honeycomb carrier or integral porous core structures can be separately configured as other independent embodiments and are not considered the preferred core structure of this application.

Detailed Implementation

[0062] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0063] The following detailed description of the implementation method of the present invention is in conjunction with the accompanying drawings. The description is only a partial embodiment and not all embodiments. For clarity, representations and descriptions unrelated to the present invention are omitted in the drawings and description.

[0064] To provide a clearer understanding of the technical features, objectives, and beneficial effects of this invention, the following detailed description of the technical solution is provided. Obviously, the described embodiments are only a portion of the embodiments of this invention, not all of them, and should not be construed as limiting the scope of implementation of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the protection scope of this invention.

[0065] like Figures 1-4 As shown, the present invention provides a micro-liquid-containing gas flow disturbance and crushing system for combustion equipment, including a water-containing medium supply unit 1, a micro-liquid-containing gas flow generation component 2, a liquid volume constraint structure 3, a disturbance and crushing component 4, and a combustion equipment connection end 5.

[0066] Example 1 This embodiment provides a micro-liquid-containing gas flow disturbance and crushing system 100 for combustion equipment, including a water-containing medium supply unit 1, a micro-liquid-containing gas flow generation component 2, a liquid volume constraint structure 3, a disturbance and crushing component 4, and a combustion equipment connection end 5.

[0067] The aqueous medium supply unit 1 is a container structure used to hold water, water-alcohol mixture, emulsion, or other aqueous medium 11. The container may be equipped with a liquid level observation section, a liquid injection section, a liquid drainage section, or a maintenance section, but these structures are not considered essential innovations of this invention.

[0068] The trace liquid-containing gas flow generation component 2 is disposed above or adjacent to the water-containing medium supply section 1. Under the action of engine intake negative pressure, burner ejector negative pressure, Venturi ejector, or pressure drive, the gas sweeps across the surface of the water-containing medium 11. Due to the gas flow velocity, liquid surface fluctuation, and gas-liquid interface shearing, some trace liquid droplets are entrained into the gas flow, forming a liquid-containing gas flow.

[0069] The liquid volume constraint structure 3 is located in the outlet area of ​​the micro-liquid-containing gas flow generating component 2, and includes a height-limiting liquid surface structure, a liquid-blocking wall 33, a flow-deflecting baffle 32, a gas-liquid separation space 31, and a droplet impact and fall surface 34. Larger droplets impact the liquid-blocking wall 33 or the fall surface under inertia and flow back to the water-containing medium supply section 1, while smaller droplets enter the disturbance and crushing component 4 with the airflow. Thus, the fluid entering the disturbance and crushing component 4 is not a simple humidified airflow, nor a direct jet flow from the liquid nozzle, but a restricted liquid-containing gas flow carrying droplets.

[0070] The disturbance and breakup assembly 4 includes a disturbance channel unit 41. Within this unit 41, three disturbance sections 42 are arranged along the flow direction of the liquid-containing gas stream: a spiral disturbance section 425, a narrowing orifice section, and an expanding cavity section. The liquid-containing gas stream first passes through the spiral disturbance section 425, creating rotational disturbance that stretches and shears the entrained droplets against the wall. It then enters the narrowing orifice section, where further breakup occurs under local acceleration and orifice jetting. Afterward, it enters the expanding cavity section, where further breakup and homogenization occur under local diffusion, collision, and pressure drop changes. Thus, the droplet stretching, breakup, wall shearing, or orifice jetting dispersion state formed in the previous disturbance section 42 is transmitted along the flow direction to the next disturbance section 42, forming a continuous secondary breakup path.

[0071] In this embodiment, a transition cavity 424 for perturbation sections can be provided between the spiral perturbation section 425 and the narrowing orifice section, and between the narrowing orifice section and the expansion cavity section. The transition cavity 424 allows the swirling, droplet stretching, wall shearing, or orifice dispersion state formed by the previous perturbation section 42 to continue into the next perturbation section 42, rather than allowing the liquid-containing gas flow to be directly output after the previous perturbation section 42. In other embodiments, adjacent perturbation sections 42 can also be connected by an inter-section contraction channel or an inter-section expansion channel to regulate the velocity, pressure, or droplet dispersion state of the liquid-containing gas flow when it enters the next perturbation section 42.

[0072] The combustion equipment connection end 5 is connected to the outlet of the disturbance and breakup component 4. The aerosol or enhanced gas-liquid composite phase enters the engine intake side 61, the combustor mixing section 62, or the boiler combustion air duct 63 through the connecting pipeline. In this embodiment, instead of simply using a liquid container to generate water-containing air, a limited liquid volume liquid-containing airflow is first formed, and then it undergoes continuous secondary breakup through the disturbance channel unit 41 containing at least two disturbance sections 42, thereby forming an aerosol or enhanced gas-liquid composite phase that can be fed into the combustion equipment 6.

[0073] Example 2 In this embodiment, the micro-liquid gas flow generating component 2 does not use open liquid surface swirling, but instead uses liquid film swirling or capillary wetting element 25 liquid supply method.

[0074] The aqueous medium supply unit 1 provides a thin liquid film 242 into the airflow channel 22 through capillary channels, porous liquid permeation components 26, fiber wetting components, or microporous liquid supply components. As the gas flows along the surface of the liquid film, it is entrained by a small number of liquid droplets under shearing action, forming a liquid-containing airflow. Due to structural limitations on the liquid film thickness, capillary liquid supply rate, or microporous liquid supply rate, the amount of liquid entering the downstream disturbance and breakup component 4 is constrained.

[0075] The disturbance breaking component 4 in this embodiment includes at least two disturbance sections 42. For example, the first disturbance section 421 is a misaligned orifice plate section, the second disturbance section 422 is a collision wall section 429, and the third disturbance section 423 is a baffle section. The liquid-containing gas flow carrying droplets is divided into multiple local jets after passing through the misaligned orifice plate section, and then impacts the collision wall section 429 to break up the droplets. After passing through the baffle section, the flow direction is changed and the droplet agglomeration structure is further dispersed.

[0076] Non-preferred description of submersible contact method In some pressure-driven or pumping conditions, the gas-liquid contact method can also include submerged dispersion contact. This method allows the gas or pressurized fluid to form bubbles in the liquid phase before entering the gas-liquid separation space 31. However, for low-resistance systems that rely on engine intake negative pressure or combustor ejector negative pressure, submerged dispersion contact usually introduces significant resistance and may cause fluctuations in the liquid phase carryover. Therefore, this invention preferably employs liquid surface contact, liquid film contact, capillary wetting contact, porous seepage contact, or micro-supply contact methods.

[0077] It should be noted that the core of this application is not to generate water-containing air through submerged bubbling, but to allow the water-containing medium 11 to enter the airflow in a limited liquid volume manner, and to undergo continuous secondary crushing in the downstream disturbance and breakup component 4 containing at least two disturbance sections 42, thereby forming an aerosol containing micro-droplets or an enhanced gas-liquid composite phase.

[0078] Example 3 In this embodiment, the disturbance breaking component 4 includes a disturbance channel unit 41a, in which a plurality of disturbance sections 42 with the same structure are arranged to form an isomorphic series structure.

[0079] For example, three narrow-diameter orifices are arranged along the flow direction within the disturbance channel unit 41a, with an expansion buffer zone 424 between adjacent narrow-diameter orifices. When the confined liquid-containing gas stream passes through each narrow-diameter orifice, it undergoes local acceleration, orifice shearing, and pressure changes, followed by droplet stretching, rupture, and secondary dispersion within the subsequent expansion buffer zone 424. Through the repeated action of multiple narrow-diameter orifices, the proportion of large droplets can be reduced, and the dispersion fluctuations of the output aerosol can be minimized.

[0080] In the isomorphic series structure, the expansion buffer zone 424 between two adjacent narrow-diameter orifices is not the final output cavity, but is used to continue to transfer the orifice dispersion state formed by the previous narrow-diameter orifice to the next narrow-diameter orifice, so that the liquid-containing gas flow breaks continuously during multiple local acceleration, expansion and re-acceleration processes.

[0081] Example 4 In this embodiment, multiple disturbance sections 42 of different types are provided in the disturbance channel unit 41b to form a heterogeneous series structure.

[0082] For example, the disturbance channel unit 41b is sequentially provided with a spiral disturbance section 425, a local throat section 426, an eccentric expansion cavity section 427, and a labyrinth flow channel section 428 along the flow direction. When the liquid-containing gas flow passes through the spiral disturbance section 425, a rotational component is formed; when it passes through the local throat section 426, acceleration and pressure drop occur; after entering the eccentric expansion cavity section 427, eccentric collision, local backflow, and pressure pulsation are formed; and then, when it passes through the labyrinth flow channel section 428, multiple reversals and droplet wall shearing occur.

[0083] In the heterogeneous series structure, the disturbance sections 42 are not independent parallel components, but are connected in series along the flow direction of the same disturbance channel unit 41b. The swirling flow, pressure drop, droplet stretching, or liquid film rupture state generated by the previous disturbance section 42 will enter the next disturbance section 42, and be disturbed, broken, or homogenized again in the next disturbance section 42.

[0084] Example 5 In this embodiment, the disturbance breaking component 4 includes an inlet collecting chamber 43, an outlet collecting chamber 44, and at least two parallel disturbance channel units 41 located between the two.

[0085] Each disturbance channel unit 41 contains at least two disturbance sections 42. Multiple disturbance channel units 41 may have the same structure or different structures. For example, the first disturbance channel unit 411 contains a spiral disturbance section 425 and a reduced-diameter orifice section; the second disturbance channel unit 412 contains a misaligned orifice plate section and an expansion cavity section; and the third disturbance channel unit 413 contains a Venturi section and a collision wall section 429.

[0086] The inlet collecting chamber 43 is used to distribute the limited liquid-containing gas flow to each parallel disturbance channel unit 41. The outlet collecting chamber 44 is used to converge the aerosols or enhanced gas-liquid composite phases output from each channel. The pressure pulsations, velocity pulsations, or vorticity structures output from different channels are further superimposed in the outlet collecting chamber 44, which can form a secondary shearing and homogenization effect. In high-flow-rate engine, burner, boiler duct, or generator set applications, a single disturbance channel unit 41 may be difficult to balance the throughput and crushing effect due to pressure loss, flow velocity, or uneven droplet distribution. The disturbance crushing assembly 4 can be composed of multiple disturbance channel units 41 connected in parallel. The inlet collecting chamber 43 distributes the limited liquid-containing gas flow to each disturbance channel unit 41. Each disturbance channel unit 41 is provided with at least two series-connected disturbance sections 42 to form continuous secondary crushing in each branch channel. The outlet collecting chamber 44 then converges and outputs the aerosols or enhanced gas-liquid composite phases output from different disturbance channel units 41.

[0087] Example 6 In this embodiment, the disturbance and breakup assembly 4 forms at least two parallel disturbance channel units 41 within a housing or a core platform. Each parallel disturbance channel unit 41 contains at least two disturbance sections 42 arranged along the liquid-containing gas flow direction. For example, the first parallel disturbance channel unit 411 contains a spiral disturbance section 425 and a reduced-diameter orifice section in sequence; the second parallel disturbance channel unit 412 contains a staggered orifice plate section and an expansion cavity section in sequence; and the third parallel disturbance channel unit 413 contains a Venturi section and a collision wall section 429 in sequence. The channels can be isomorphically connected in series or heteromorphically connected in series; the type, number, arrangement order, channel hydraulic diameter, local pressure drop structure, or outlet angle of the disturbance sections 42 between different channels can be the same or different.

[0088] The liquid-containing gas flow with limited volume is distributed to each parallel disturbance channel unit 41 through the inlet collecting chamber 43. Within each channel, it undergoes a continuous secondary crushing path formed by at least two disturbance sections 42. After the outputs from each channel converge in the outlet collecting chamber 44, velocity pulsation superposition, local shearing, and homogenization can occur. This structure is used to cover the combined implementation of "multi-channel parallel + multi-section series within the channel" within a single disturbance crushing component 4.

[0089] In implementations with higher throughput or longer processing paths, Figure 7 The disturbance breaking component 4 shown can be used as a parallel disturbance module 4, or two or more such modules. Figure 7 The parallel disturbance modules shown can be connected in series along the outlet direction C of the gas or liquid-containing gas stream. The outlet collecting chamber 44 of the preceding parallel disturbance module is connected to the inlet collecting chamber 43 of the following parallel disturbance module; this connection can be a direct connection or a connection through a transition channel, a contraction channel, or an expansion channel. The limited liquid-containing gas stream first completes the series disturbance within the channel and the parallel expansion between channels in the preceding disturbance and breaking component 4, and then enters the following inlet collecting chamber 43 through the preceding outlet collecting chamber 44, where it continues to be broken and homogenized, thus forming a continuous secondary / multiple breaking path.

[0090] The aforementioned disturbance and crushing component 4, which serves as the parallel disturbance module 4, can be a replaceable core component or a non-removable integrated welded, glued, hot-melted, press-fitted, or integrally molded component. The difference between removable and non-removable components lies only in the manufacturing, maintenance, and sealing strategies, and does not alter the basic system chain of active supply of water-containing medium, limited liquid volume liquid-containing gas flow, continuous secondary / multiple crushing by the disturbance and crushing component 4, and the output of the combustion equipment 6.

[0091] Example 7 In this embodiment, at least one disturbance channel unit 41c includes a swirl guide section 430 and a swirl pressure drop section 434 connected in sequence.

[0092] The swirl guide section 430 can employ a helical guide rib 431, helical blade 432, swirl vane cascade, tangential inlet 433, or offset guide structure to convert the axial momentum of the liquid-containing gas flow into a rotating flow with a tangential velocity component. The swirl pressure drop section 434 is located downstream of the swirl guide section 430 and includes a tangential expansion cavity 435, an eccentric expansion cavity 436, a local throat expansion cavity 437, or an offset pressure drop cavity.

[0093] When the rotating flow carrying droplets enters the swirling pressure drop section 434, it is subjected to radial pressure gradient, local pressure drop zone, backflow zone, and pressure pulsation, causing the droplets to undergo stretching, breakup, wall shearing, and secondary dispersion. Compared with a simple straight-through channel or a single narrow-diameter orifice, this embodiment can form a complex disturbance field. Figure 8 and Figure 9 This illustration is only intended to show one possible combination of the swirl guide section 430 and the swirl pressure drop section 434. The swirl guide section 430 is not limited to the illustrated spiral guide rib 431, swirl blade 432, or tangential inlet 433 structure, and the swirl pressure drop section 434 is not limited to the illustrated tangential expansion cavity 435, eccentric expansion cavity 436, or local throat expansion cavity 437. Any series structure that can generate a rotational component, local pressure drop, pressure pulsation, wall shear, or secondary droplet breakage effect in the restricted liquid-containing gas flow can be used as an equivalent or alternative structure in this embodiment.

[0094] Supplementary notes on porous dispersion joints In other embodiments, the disturbance section 42 may also include a porous dispersion section for generating localized perforation, dispersion, or wall shearing effects on the liquid-containing gas flow. The porous dispersion section may be used as one of a plurality of disturbance sections 42 within the disturbance channel unit 41, rather than as the preferred independent disturbance and breakup assembly 4 of this application.

[0095] Example 8 In this embodiment, the disturbance and breakup component 4 is configured as a replaceable core component. The replaceable core component includes at least one disturbance channel unit 41, and each disturbance channel unit 41 has at least two disturbance sections 42 arranged along the flow direction of the liquid-containing gas flow. The disturbance section 42 can be one or more of the following: a narrow-diameter orifice section, an expansion cavity section, an eccentric cavity section, a local throat section 426, a spiral disturbance section 425, a misaligned orifice plate section, a collision wall section 429, a baffle section, a labyrinth channel section 428, a venturi section, a swirling pressure drop section 434, a tangential inlet cavity section 433, or a porous dispersion section.

[0096] The replaceable core assembly can be installed in the housing via snap-fit, thread, flange, plug-in seal, compression seal, end cap compression, or clamp connection. Users can select different numbers of disturbance sections 42, different arrangement sequences of disturbance sections, different hydraulic diameters of channels, or different numbers of parallel channels for the disturbance and breaking core assembly based on the air intake flow rate, negative pressure range, fuel type, type of water-containing medium 11, or installation space of the combustion equipment 6.

[0097] During maintenance, only the agitator core needs to be replaced, without replacing the water-containing medium supply unit 1, the trace liquid-containing gas flow generation component 2, or the outer casing. This structure reduces maintenance workload and facilitates the use of the same outer casing platform to accommodate different agitator cores across different combustion devices 6.

[0098] Example 9 In some applications by OEMs or burner manufacturers, the system can be configured with a micro pump, a pressure liquid supply device, a compressed air ejector, or a solenoid valve. In this case, the water-containing medium 11 can enter the airflow channel 22 through the micro-liquid supply port 27, the micro-porous liquid supply element, or the capillary wetting element 25, forming a limited liquid volume liquid-containing airflow.

[0099] This invention can operate without closed-loop control by an electronic control unit. For example, it can form a limited liquid-containing gas flow by using engine intake negative pressure, burner ejector negative pressure or Venturi ejector, and complete continuous secondary crushing by disturbing the crushing component 4.

[0100] In OEM or burner system integration scenarios, pressure sensors, flow sensors, temperature sensors, level sensors, solenoid valves, micro pumps, or controllers can be added to monitor operating conditions, assist in liquid supply, or achieve start-stop control. However, the aforementioned electronic control components are not necessary conditions for the establishment of this invention; even if pumps, pressure liquid supply, solenoid valves, or sensors are used, the core of this invention still lies in maintaining the structural chain of "continuous secondary crushing after the limited liquid volume liquid-containing gas flow enters the disturbed crushing component 4".

[0101] Example 10 This invention can be applied to engines, burners, boilers, kilns, gas turbines, or generator sets 64. In some embodiments, the engine may include a gasoline engine, a diesel engine, a gas engine, or a dual-fuel engine, etc.

[0102] In the engine scenario, the combustion equipment connection end 5 can be connected to the throttle front 611, the throttle rear 612, the intake manifold 613, the front end of the turbocharger, the rear end of the turbocharger, the intercooler front and rear pipes, or the intake main pipe.

[0103] In a burner or boiler scenario, the combustion equipment connection end 5 can be connected to the burner primary air passage 621, secondary air passage 622, fuel-air mixing section, combustion equipment 6 air passage, or combustion air duct 63.

[0104] The aerosols or enhanced gas-liquid composite phases output by this invention, after entering the combustion equipment 6, can be used for heat load suppression, knock margin compensation, heat decay suppression, deposition tendency reduction, or combustion organization optimization. The specific degree of effect depends on factors such as fuel type, excess air coefficient, combustion chamber temperature, residence time, flow field organization, aerosol particle size distribution, and system installation location. This invention does not necessarily limit the achievement of specific emission reduction rates or specific chemical reaction product concentrations.

[0105] The structure of this invention can be made of metal, engineering plastics, composite materials, ceramics, or combinations thereof. The disturbance and crushing component 4 can be formed by machining, injection molding, die casting, additive manufacturing, stamping and stacking, modular assembly, or composite processing.

[0106] This invention is applicable to various scenarios such as original equipment manufacturer (OEM) integration of combustion equipment 6, aftermarket modification, burner condition modification, boiler combustion organization optimization, engine high-load thermal decay suppression, and combustion auxiliary control of small generator sets 64, and has industrial applicability.

It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
