Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial energy system optimization, in particular to a steam system balance and steam power system optimization energy-saving mechanism. BACKGROUND

[0002] The steam power system is the core energy supply unit of industrial production. By converting primary energy such as fuel into secondary energy such as steam and electricity, it provides the necessary heat and power for process production. Its operating efficiency directly determines the energy consumption cost, production continuity and environmental protection benefit of the enterprise, and is the key breakthrough for industrial energy saving and efficiency improvement. With the development of industrial intelligence and greenness, the steam system has formed a complex structure of multiple pressure grade pipe networks interlaced and multiple load working conditions switched. The comprehensive requirements for system balance regulation and energy saving optimization have significantly improved.

[0003] The core contradiction of steam system balance and power optimization energy saving is the fundamental conflict between global energy coordination demand and local device isolated optimization. The energy conversion, transmission, utilization and recovery of the steam system are a closed loop that is interrelated, but it has long relied on the dispersed improvement of single devices (such as independent balance valves, trap valves and recovery pumps), which is difficult to adapt to the complex characteristics of steam phase sensitivity, load dynamic fluctuation and pipe network pressure coupling, resulting in two major systemic defects in the existing technical architecture. Firstly, the system balance is unstable and the energy utilization efficiency is low. Traditional technology mainly relies on static device optimization and lacks a global coordinated regulation mechanism. The steam transmission link is designed unreasonably due to condensate discharge, and the dryness treatment is missing, resulting in insufficient steam dryness and frequent water hammer phenomena, which not only damages the pipeline equipment but also reduces the heat exchange efficiency. The heat exchange link causes waste of heat transfer area and attenuation of heat transfer due to the direct use of superheated steam and the formation of water film in the boiler. The additional increase of steam consumption. The condensate recovery link will cause flash loss due to excessive back pressure and unreasonable recovery method, and the condensate recovery rate of the end workshop is insufficient, resulting in waste of water resources and heat energy. Secondly, the long-term reliable operation guarantee is missing and the whole life cycle cost is high. The existing devices are mainly simple stacking of isolated functional units, and lack real-time sensing and early warning capability for key state parameters such as steam dryness, pipe fouling rate, sealing interface leakage trend and pressure dynamic deviation, and are in a "black box operation" state. Equipment maintenance relies on regular shutdown and disassembly inspection, and cannot predict potential risks such as heat exchange efficiency decay caused by fouling and steam leakage caused by sealing failure. Not only does it cause frequent unplanned shutdowns and poor production continuity, but it also results in high maintenance costs. In addition, steam leakage, water hammer impact and condensate oxidation corrosion not only pose a safety hazard, but also cause energy waste and indirect emission of greenhouse gases, which does not meet the requirements of green industrial development.

[0034] The technical solutions of 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.

[0035] like Figure 1 As shown, this embodiment discloses a steam system balancing and steam power system optimization and energy-saving mechanism, including a main cavity adaptive control component 100 and a secondary cavity flash recovery balancing component 200. The secondary cavity flash recovery balancing component 200 is installed on one side of the outer wall of the main cavity adaptive control component 100.

[0036] like Figure 8 as well as Figure 10-11As shown, the main cavity adaptive control assembly 100 includes a hollow titanium alloy float 111, a push rod 112, two levers 115, two connecting rods 116, four rollers 117, four slides 119, a conical valve core 122, a valve seat 123, and a conical bottom 124. The hollow titanium alloy float 111 is used to sense the rise and fall of the water level in real time. The top two sides of the push rod 112 are provided with bidirectional conical surfaces, and the bottom of the long side of the two levers 115 is provided with a cone that matches the bidirectional conical surface of the push rod 112. The push rod 112 and two levers 115 cooperate for displacement transmission and amplification. Two connecting rods 116 are used to support the short side displacement of the two levers 115. Each pair of rollers 117 are connected to the outer walls of a corresponding connecting rod 116, and each pair of rollers 117 are used to roll in the corresponding two slide grooves 119. The conical valve core 122 and the conical bottom 124 are precisely fitted together, and the conical valve core 122 and the conical bottom 124 are used to achieve linear regulation of steam flow.

[0037] like Figure 12-13 As shown, the secondary chamber flash evaporation recovery balancing assembly 200 includes a conical flash evaporation channel 210, a U-shaped liquid seal pipe 211, and a two-way differential pressure balancing valve 212. The inner surface of the conical flash evaporation channel 210 is provided with a spiral guide groove, and the conical structure of the conical flash evaporation channel 210 is used to reduce the resistance to flash steam inflow. The spiral guide groove is used to guide the steam to rotate and flow. The U-shaped liquid seal pipe 211 realizes the non-powered backflow of condensate. The two-way differential pressure balancing valve 212 has a built-in double piston, and the two-way differential pressure balancing valve 212 is used to keep the pressure in dynamic balance at all times.

[0038] This embodiment primarily addresses the core contradiction between steam system balance and energy optimization for energy conservation: the fundamental conflict between the system's overall energy coordination requirements and the isolated optimization of local equipment. Specifically, the energy conversion, transmission, utilization, and recovery of a steam system form an interconnected closed loop, yet it has long relied on decentralized improvements to individual devices such as independent balancing valves, steam traps, and recovery pumps. This approach struggles to adapt to the complex characteristics of steam phase sensitivity, dynamic load fluctuations, and pipeline pressure coupling, resulting in two major systemic defects in the existing technical architecture. First, system instability and low energy utilization efficiency arise because traditional technologies primarily focus on static equipment optimization, lacking a global coordinated control mechanism. Second, in the steam transmission stage, unreasonable condensate removal design and lack of drying treatment lead to insufficient steam dryness and frequent water hammer, damaging pipeline equipment and reducing heat exchange efficiency. Third, in the heat exchange stage, the direct use of superheated steam and the formation of a water film in the reboiler result in wasted heat exchange area and reduced heat transfer efficiency. The problems include: increased steam consumption; excessive back pressure and unreasonable recovery methods in the condensate recovery process leading to flash evaporation losses; insufficient condensate recovery rate in the end-of-line workshops, resulting in a double waste of water resources and heat energy; secondly, the lack of long-term reliable operation guarantees and high life-cycle costs; existing equipment is mostly a simple stacking of isolated functional units, lacking real-time perception and early warning capabilities for key parameters such as steam dryness, coil scaling rate, leakage trend at sealing interfaces, and dynamic pressure deviation, operating in a "black box" state; equipment maintenance relies on periodic shutdowns for disassembly and inspection, making it impossible to predict potential risks such as heat exchange efficiency degradation caused by scaling and steam leakage caused by sealing failure, resulting in frequent unplanned shutdowns, poor production continuity, and high maintenance costs; furthermore, problems such as steam leakage, water hammer, and condensate oxidation and corrosion pose safety hazards and cause energy waste and indirect greenhouse gas emissions, which do not meet the requirements of green industrial development.

[0039] This embodiment addresses the problems of existing technologies by achieving a unified time and space for steam system balance control and energy-saving optimization through the systematic collaboration of the main cavity adaptive control component 100 and the secondary cavity flash evaporation recovery balancing component 200. The main cavity adaptive control component 100 relies on a purely mechanical closed loop formed by the water level sensing of the hollow titanium alloy float 111, the conical transmission of the double lever 115, the drag reduction of the roller 117 and the slide 119, and the flow interception of the conical valve core 122, thus fundamentally solving the inherent problems of failure and lagging flow control in existing electronic control systems under high temperature and high pressure environments. Secondly, the secondary cavity flash evaporation recovery balancing component 200, through the fluid dynamic coupling of the conical flash evaporation channel 210, the bidirectional differential pressure balancing valve 212, and the U-shaped liquid seal pipe 211, utilizes the spiral guide channel and the spiral auxiliary heat exchange coil 206 to achieve in-situ recovery of flash steam and dynamic pressure balance, ensuring the system is always in an optimal state of heat exchange and energy recovery. Finally, this invention achieves real-time dynamic adjustment of water level, steam flow rate, pressure, and waste heat recovery through the coordinated response of the three core components. This system thoroughly solves process pain points such as reboiler water accumulation, flash steam degradation, water hammer, and difficulty in condensate recovery, ensuring the energy conversion efficiency and operational stability of the steam system. The main chamber adaptive control component 100 features a hollow titanium alloy float 111, lever 115 linear transmission, and roller 117 drag reduction design, thereby improving heat exchange efficiency. Furthermore, the secondary chamber flash steam recovery balancing component 200's spiral flow guide and bidirectional pressure differential balancing mechanism can accommodate steam fluctuations at different pressure levels, improving flash steam recovery rate and condensate recovery rate, significantly reducing steam waste and energy loss. Secondly, the single shell-side integration of three core functions—flow regulation, waste heat recovery, and pressure balancing—significantly reduces equipment complexity and potential failure points through the reuse of steam flow dynamics and mechanical transmission. It achieves automatic logic of "flow regulation upon water level rise, balancing upon pressure imbalance, and recovery upon flash steam generation," completely eliminating manual intervention and control errors, perfectly adapting to the large-scale, continuous operation needs of steam-intensive industries such as petrochemicals and cogeneration.

[0040] according to Figure 3 As shown, the main cavity adaptive control component 100 also includes a main cavity housing 101. One end of the outer wall of the main cavity housing 101 is connected to a first tube sheet 104. One side of the outer wall of the first tube sheet 104 is connected to a U-shaped heat exchange coil 102. The inlet end and outlet end of the U-shaped heat exchange coil 102 are respectively connected to a first inlet 106 and a first outlet 107.

[0041] In this embodiment of the invention, firstly, the main cavity shell 101 serves as the core supporting structure of the main cavity adaptive control component 100, providing a stable installation reference for all internal transmission components and heat exchange components. The rigid connection between the main cavity shell 101 and the first tube sheet 104 ensures the structural sealing under high-pressure steam environment. Secondly, the U-shaped heat exchange coil 102 adopts a multi-parallel layout, maximizing the contact area between steam and process medium. Combined with the diversion design of the first inlet 106 and the first outlet 107, the process medium flows evenly through each coil, avoiding local heat exchange dead zones. Structurally, this ensures the stability of heat exchange efficiency and solves the problems of insufficient heat exchange area and uneven medium flow in traditional heat exchangers.

[0042] according to Figure 3 as well as Figure 5 As shown, a second tube sheet 105 is fitted onto one end of the outer surface of the U-shaped heat exchange coil 102, according to... Figure 9 As shown, corrugated compensators 127 are fitted at the joints of the U-shaped heat exchange coil 102, the first tube sheet 104, and the second tube sheet 105. Two elastic turbulence rings 103 are symmetrically fitted on the outer surface of the U-shaped heat exchange coil 102. A connector 108 is bolted to the bottom of the inner surface of the main cavity shell 101. A first limiting protection block 109 is fixedly connected to the top of the connector 108. A second limiting protection block 110 is bolted to the top of the first limiting protection block 109. A hollow titanium alloy float 111 is suspended between the first limiting protection block 109 and the second limiting protection block 110.

[0043] In this embodiment of the invention, firstly, the second tube sheet 105 and the first tube sheet 104 work together to fix both ends of the U-shaped heat exchange coil 102, preventing the U-shaped heat exchange coil 102 from shifting under high temperature and high pressure; wherein the corrugated compensator 127 accurately absorbs the thermal expansion of the U-shaped heat exchange coil 102 caused by temperature changes, avoiding cracking and leakage caused by stress concentration at the connection between the U-shaped heat exchange coil 102 and the second tube sheet 105 and the first tube sheet 104, thereby significantly improving the safety of equipment operation; secondly, the elastic turbulence ring 103 generates micro-vibrations with the steam flow, disrupting the surface of the U-shaped heat exchange coil 102. The boundary layer and scale adhesion conditions of the surface, combined with the micro-nano coating on the outer surface of the U-shaped heat exchange coil 102, doubly inhibit scale formation; and the connector 108 is fixed to the bottom of the main cavity shell 101, providing stable support for the first limit protection block 109 and the second limit protection block 110. The limiting space formed by the two strictly constrains the lifting stroke of the hollow titanium alloy float 111, which not only prevents the hollow titanium alloy float 111 from moving excessively and causing the transmission mechanism to jam, but also avoids insufficient stroke affecting the flow control accuracy, completely solving the pain points of traditional hollow titanium alloy float 111 control without effective limit and easy loss of control.

[0044] according to Figure 7 as well as Figure 10As shown, the top of the hollow titanium alloy float 111 and the bottom of the push rod 112 are fixedly connected. Two support plates 113 are symmetrically connected to the inner surface of the main cavity shell 101. A rotating rod 114 is inserted between the outer walls of each pair of support plates 113. The outer surface of each rotating rod 114 is rotatably connected to the inner surface of a corresponding lever 115.

[0045] In this embodiment of the invention, firstly, the fixed connection between the hollow titanium alloy float 111 and the push rod 112 ensures lossless transmission of water level displacement. The lightweight and high-strength characteristics of the hollow titanium alloy float 111 make it highly responsive in condensed water, and even a small change in water level can drive the push rod 112 to move synchronously. Secondly, the support plate 113 is symmetrically distributed on the inner wall of the main cavity shell 101, which can provide a stable rotation fulcrum for the rotating rod 114. The rotational cooperation between the rotating rod 114 and the lever 115 realizes the flexible swing of the lever 115. This structural design avoids the problems of easy wear and jamming of traditional transmission fulcrums, ensures the long-term smoothness of the conical transmission of the double lever 115, and provides a reliable guarantee for displacement amplification.

[0046] according to Figure 7 As shown, the top of the short side of each of the two levers 115 is rotatably connected to one end of a corresponding connecting rod 116. The top of the inner surface of the main cavity housing 101 is symmetrically bolted with two support frames 120. The opposite side of each of the two support frames 120 is bolted with an annular guide plate 118, and every two slide grooves 119 are symmetrically opened on the outer surface of the annular guide plate 118.

[0047] In this embodiment of the invention, the short side of lever 115 is firstly rotated to connect with connecting rod 116, converting the rotational motion of lever 115 into the linear displacement of connecting rod 116, resulting in a transmission connection without rigid impact. Support frame 120 is fixed to the top of main cavity housing 101 by bolts, providing solid support for annular guide plate 118 and ensuring that annular guide plate 118 does not deform under high-pressure steam environment. At the same time, the groove 119 on annular guide plate 118 is precisely matched with roller 117, with rolling friction replacing traditional sliding friction, significantly reducing transmission resistance. Meanwhile, the annular structure of groove 119 strictly limits the movement trajectory of connecting rod 116, ensuring synchronous displacement of connecting rods 116 on both sides, avoiding uneven force on conical valve core 122 due to transmission offset, and ensuring linear accuracy of steam flow regulation.

[0048] according to Figure 6 as well as Figure 8 As shown, a pull rod 121 is fixedly connected to one side of the two connecting rods 116. A spring 125 is elastically connected to the bottom of the pull rod 121. A fixing plate 126 is connected to the bottom of the spring 125. The top of the fixing plate 126 is bolted to the bottom of the two annular guide plates 118.

[0049] In this embodiment of the invention, the fixed connection between the two connecting rods 116 and the pull rod 121 firstly realizes the convergence of transmission forces on both sides, ensuring that the pull rod 121 is balanced under force, and driving the conical valve core 122 to rise and fall smoothly; the elastic support design of the spring 125 provides a reset assistance to the pull rod 121 when the water level drops, so that the conical valve core 122 can quickly return to its position, avoiding reset lag caused by gravity. At the same time, the buffering effect of the spring 125 can absorb slight vibrations during the transmission process, protecting the sealing surface between the conical valve core 122 and the cone bottom 124; the rigid connection between the fixed plate 126 and the annular guide plate 118 provides a stable support point for the spring 125, ensuring that the elastic force of the spring 125 is always stable, further improving the accuracy and reliability of the adjustment of the conical valve core 122.

[0050] according to Figure 8 As shown, the top of the pull rod 121 is fixedly connected to the bottom of the conical valve core 122, the top of the main cavity housing 101 is connected to the valve seat 123, and the conical bottom 124 is integrally formed on the bottom of the inner surface of the valve seat 123.

[0051] In this embodiment of the invention, the fixed connection between the pull rod 121 and the conical valve core 122 ensures the directness of displacement transmission. The conical surface at the bottom of the conical valve core 122 and the conical surface of the conical base 124 are precisely fitted to form a line sealing structure, which significantly improves the steam sealing performance and effectively reduces the leakage rate. The connection design between the valve seat 123 and the main cavity housing 101 ensures that the steam flows directly through the mating surface of the conical valve core 122 and the conical base 124, and the flow regulation response is rapid. This integrated structure avoids the regulation lag caused by the connection of traditional valve pipelines and realizes the real-time linkage of "water level change, conical valve core 122 action, and flow regulation", which fundamentally solves the problem of failure of existing electric control valves under high temperature and high pressure.

[0052] according to Figure 12-13 As shown, the secondary cavity flash evaporation recovery balance assembly 200 also includes a secondary cavity shell 201. The inner surface of the secondary cavity shell 201 is covered with a heat insulation layer 202. The two ends of the outer wall of the secondary cavity shell 201 are respectively connected to an end cap 203 and a main and secondary cavity partition plate 204. One side of the outer wall of the main and secondary cavity partition plate 204 is fixedly connected to the opposite side of the main cavity shell 101.

[0053] In this embodiment of the invention, the secondary chamber shell 201 firstly provides an independent cavity for flash steam recovery and pressure balancing. The insulation layer 202 on its inner wall effectively reduces heat loss in the secondary chamber and improves waste heat recovery efficiency. The end cap 203 adopts a detachable design, which facilitates the inspection and maintenance of the internal spiral auxiliary heat exchange coil 206 and reduces equipment maintenance costs. Furthermore, the rigid connection between the main and secondary chamber partition plate 204 and the main chamber shell 101 achieves complete isolation between the main chamber shell 101 and the secondary chamber shell 201, preventing cross-flow of steam and liquid between the two chambers, creating an independent environment for pressure balancing and flash steam recovery, and solving the problem of low recovery efficiency caused by the interconnection of the two chambers in traditional equipment.

[0054] according to Figure 12 as well as Figure 13 As shown, three annular frames 205 are fixedly connected between the inner surfaces of the secondary cavity shell 201, and a spiral auxiliary heat exchange coil 206 is connected between the inner surfaces of the three annular frames 205. The feed end and the discharge end of the spiral auxiliary heat exchange coil 206 are respectively connected to a second feed port 207 and a second discharge port 208.

[0055] In this embodiment of the invention, three annular frames 205 are uniformly distributed within the secondary cavity shell 201, providing stable support for the spiral auxiliary heat exchange coil 206 and preventing deformation of the spiral auxiliary heat exchange coil 206 under steam impact. The spiral structure of the spiral auxiliary heat exchange coil 206 significantly increases the contact area and contact time with the flash steam, enabling the sensible and latent heat of the flash steam to be fully transferred to the low-temperature medium inside the spiral auxiliary heat exchange coil 206. The independent design of the second inlet 207 and the second outlet 208 ensures smooth flow of the low-temperature medium, achieving efficient recovery and secondary utilization of waste heat, significantly reducing the overall energy consumption of the steam system, and solving the energy waste problem caused by the direct discharge of traditional flash steam.

[0056] according to Figure 12-13 As shown, the bottom of the inner surface of the secondary cavity shell 201 is connected to a condensate outlet 209. A conical flash evaporation channel 210 is opened on one side of the outer wall of the main and secondary cavity partition plate 204. One side of the outer wall of the main and secondary cavity partition plate 204 is connected to a two-way differential pressure balance valve 212. U-shaped liquid seal pipes 211 pass through both sides of the outer wall of the main and secondary cavity partition plate 204.

[0057] In this embodiment of the invention, firstly, the condensate outlet 209 is located at the bottom of the secondary chamber shell 201, facilitating the collection and discharge of condensate from the main chamber shell 101 and the secondary chamber shell 201, thus preventing liquid accumulation and deposition within the chamber. The conical flash evaporation channel 210 is located in the upper region of the main-secondary chamber partition plate 204. The design with a large opening facing the main chamber reduces the inflow resistance of flash steam, and the spiral guide groove on the inner wall guides the steam to rotate and flow, extending the residence time of steam in the secondary chamber shell 201, creating favorable conditions for waste heat recovery. The bidirectional differential pressure balancing valve 212 is connected to the main-secondary chamber partition plate 204, enabling it to sense the pressure difference between the main and secondary chambers in real time. Through the adaptive action of the double pistons, dynamic pressure balance is achieved, preventing steam crossflow caused by pressure imbalance between the two chambers. Secondly, the U-shaped liquid seal pipe 211 penetrates the lower region of the partition plate, realizing the unpowered backflow of liquid from the secondary chamber to the main chamber, and preventing mutual leakage of steam between the two chambers through the liquid seal column, ensuring independent and stable operation of flash recovery and pressure balance.

[0058] During operation, when the entire equipment is started up, high-pressure steam first enters the main cavity adaptive control component 100 through the valve seat 123 at the top of the main cavity housing 101. At this time, the condensate level at the bottom of the main cavity housing 101 is low, and the hollow titanium alloy float 111 is suspended at a low position between the first limit protection block 109 and the second limit protection block 110. At the same time, the conical valve core 122 is fully open under the elastic support of the spring 125. Steam flows smoothly through the outside of the U-shaped heat exchange coil 102 and undergoes efficient heat exchange with the process medium that flows in from the first inlet 106 and finally flows out from the first outlet 107. During this process, the elasticity of the outer surface of the U-shaped heat exchange coil 102... The turbulence ring 103 generates micro-vibrations with the steam flow, which, together with the micro-nano coating on the outside of the U-shaped heat exchange coil 102, doublely inhibits scale formation. Meanwhile, the corrugated compensator 127 at the connection between the U-shaped heat exchange coil 102 and the first tube sheet 104 and the second tube sheet 105 precisely absorbs thermal expansion, preventing cracking and leakage at the connection. As heat exchange continues, the condensate at the bottom of the main cavity shell 101 gradually increases. At this time, the hollow titanium alloy float 111 rises under buoyancy, driving the bottom-fixed push rod 112 to move upwards synchronously. The bidirectional conical surface at the top of the push rod 112 fits against the matching conical surface at the bottom of the long side of the double lever 115, pushing the double lever 115 to swing flexibly around the rotating rod 114 on the support plate 113. The short side of rod 115 then drives the connected rod 116 to move. The rollers 117 on both sides of the connecting rod 116 roll and reduce resistance in the grooves 119 of the annular guide plate 118, so that the connecting rod 116 smoothly pulls the pull rod 121. The pull rod 121 drives the top conical valve core 122 to rise, precisely fitting with the conical bottom 124 in the valve seat 123, linearly adjusting the steam flow to reduce water intake and prevent water accumulation in the main cavity from forming a water film that affects heat exchange. At the same time, the lifting stroke of the hollow titanium alloy float 111 is always strictly constrained by the first limit protection block 109 and the second limit protection block 110 to prevent the transmission mechanism from jamming or the flow control from being inaccurate. Meanwhile, the spring 125 provides support to the pull rod 121 when the water level drops. The reset assist ensures that the conical valve core 122 operates sensitively. At this time, the flash steam that is not completely condensed in the main chamber shell 101 enters the secondary chamber flash steam recovery balance component 200 through the conical flash steam channel 210 with a large opening at the top of the main and secondary chamber partition plate 204 facing the main chamber. The spiral guide groove on the inner wall of the channel guides the steam to rotate and flow, and prolongs its residence time in the secondary chamber shell 201. At the same time, the spiral auxiliary heat exchange coil 206 fixed by the annular frame 205 in the secondary chamber fully exchanges heat with the flash steam. The low temperature process medium flows in from the second inlet 207 and flows out from the second outlet 208, efficiently recovering the sensible heat and latent heat of the flash steam. The heat insulation layer 202 on the inner wall of the secondary chamber shell 201 reduces heat loss.During this period, the bidirectional differential pressure balancing valve 212 senses the pressure difference between the main and secondary chambers in real time through its built-in dual pistons, dynamically adjusting the pressure between the two chambers to prevent steam cross-flow. Condensate in the secondary chamber shell 201 flows back to the main chamber without power through the U-shaped liquid seal pipe 211 that passes through the lower part of the main-secondary chamber partition plate 204. Finally, all the condensate in the main and secondary chambers collects and is discharged through the condensate outlet 209 at the bottom of the secondary chamber shell 201. The entire process achieves dynamic balance and high efficiency energy saving of the steam system through pure mechanical linkage and fluid dynamic coordination between the main and secondary chambers, requiring no manual intervention and perfectly adapting to the needs of large-scale continuous industrial operations.
