Description

Technical Field

[0001] This invention relates to the field of straw processing equipment and technology, and in particular to an integrated equipment and method for solid-liquid-gas separation, condensation, jet conveying of straw vaporized materials. Background Technology

[0002] A cyclone separator is a commonly used separation device that utilizes the centrifugal force generated during the rotation of a fluid to separate materials of different densities or states. It is a typical dry gas-solid (or liquid-solid) separation device. A conventional cyclone separator usually has a conical cylinder with a material inlet pipe designed along the tangential direction. The top of the inner cylinder is equipped with several gas outlet pipes, while the bottom of the conical cylinder serves as a unified solid material outlet pipe.

[0003] Its basic working principle is: the dust-laden airflow or mixed fluid enters the separator tangentially, forming a high-speed rotating vortex inside the cylinder. Under the combined action of centrifugal force, inertial force and gravity, particles with larger density or particle size are thrown against the wall and fall along the wall, thereby separating them from the clean gas or light phase material in the central area.

[0004] Cyclone separators are widely used in chemical, metallurgical, environmental protection, and energy industries due to their simple structure, lack of moving parts, large processing capacity, and low operating and maintenance costs. In biomass processing, especially in straw degassing, biomass pretreatment, and sugar alcohol production, cyclone separators are typically used as key gas-solid separation equipment to separate the solid fibrous materials generated after degassing from the high-temperature, high-humidity gases. When combined with condensation, liquid drainage, and tail gas treatment structures, synergistic separation of solids, liquids, and gases can be achieved.

[0005] For a crucial step in straw steam explosion pretreatment, existing processes typically use a combination of traditional cyclone separators with condensers, scrubbing towers, or gas-liquid separators. Specifically, the mixture ejected from the steam explosion equipment is initially separated by a cyclone separator, and a separate condensation and cooling unit downstream treats the water vapor and low-boiling-point waste gases from the gas exiting the separator. While such segmented treatment methods can meet process requirements to some extent, they reveal significant shortcomings in more complex engineering applications. Traditional cyclone separators generally face the following challenges: (1) Traditional cyclone separators mainly focus on gas-solid separation, and their internal structural design usually does not fully consider the condensation of high-temperature water vapor, the recovery of low-boiling-point organic matter, and the drainage of condensate. However, in the straw steam explosion process, the generated airflow contains a large amount of water vapor and may carry low-boiling-point organic matter such as methanol. When the airflow is cooled inside the cyclone separator or in the downstream pipeline, the water vapor is very easy to release heat and liquefy into condensate. Existing cyclone separators lack an effective drainage structure for condensate, and the condensate is easy to accumulate on the inner wall of the separator and flow downward, remixing into the dry material below, increasing the humidity of the material, and thus causing problems such as material agglomeration, blockage, and reduced efficiency of subsequent processing.

[0006] (2) Cyclone separators and condensation devices are usually set up separately, which results in a large number of devices, complex connecting pipelines, and a large footprint in the whole system. For continuous and large-scale production devices such as straw steaming and explosion, the decentralized arrangement of each device not only increases the cost of plant construction and device installation, but also hinders the compact layout of the production line and related process optimization. The series connection of multiple devices increases the maintenance workload of the system and is not conducive to reducing the overall operating cost.

[0007] (3) Existing cyclone separators typically employ a combination of a straight cylinder and a cone. During the upstream equipment explosion process, solid materials often contain high impact energy and explosion velocity, easily causing accelerated wear on critical parts of the separator's inner cylinder wall. Most cyclone separators do not employ effective anti-wear structures or coatings, resulting in a short average service life, frequent maintenance and replacement, and significant operating costs and risks. In high-temperature and high-humidity environments, traditional separators are prone to corrosion, especially under the combined action of condensate and acidic or organic gases, further exacerbating equipment wear, affecting structural strength and sealing, and posing a hidden danger to safe production.

[0008] (4) In the straw steam explosion process, the separated residual material is prone to adhesion and scaling, which adheres to the inner wall of the separator and the air inlet and outlet, easily leading to uneven separation effect and poor efficiency. The internal structure of the cyclone separator is closed and the space is narrow, making external cleaning and maintenance operations extremely inconvenient. It usually requires stopping the machine to disassemble for manual cleaning, which results in a long maintenance cycle, seriously affecting the continuity of production and equipment utilization, and making it difficult to meet the requirements of long-term industrial operation.

[0009] (5) Existing straw steam explosion material treatment methods are usually carried out in a segmented manner, namely "cyclone separation first, independent condensation, separate tail gas treatment, and separate transportation or collection", and there is a lack of coordinated control between the treatment steps. Since solid separation, condensation and drainage, tail gas extraction, organic matter absorption and solid material transportation are completed by different equipment, the high-temperature and humid gas is prone to disordered condensation during the transfer process. The condensate can easily re-enter the solid material, resulting in problems such as increased material moisture content, agglomeration and blockage, and unstable transportation. At the same time, if low-boiling-point organic matter such as methanol in the tail gas cannot be absorbed and recovered simultaneously during the exhaust process, it may also increase the load of subsequent tail gas treatment. Therefore, the existing technology not only has the problem of equipment dispersion, but also has process defects such as discontinuous treatment process, insufficient condensate control, insufficient recovery of organic matter in tail gas, unstable gas flow organization and untimely discharge of solid materials. Summary of the Invention

[0010] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide an integrated solid-liquid-gas separation, condensation, and jet conveying device for straw vaporized materials, achieving integrated solid-liquid-gas synergistic processing of straw vaporized materials, with advantages such as compact structure, anti-clogging, high-efficiency condensation, and full recovery of low-boiling-point organic matter.

[0011] An integrated solid-liquid-gas separation, condensation, and jet conveying device for straw vaporization materials according to a first aspect embodiment of the present invention includes: A cyclone separator structure, comprising a straight cylindrical section, a conical cylindrical section connected to the lower end of the straight cylindrical section, a material inlet tangentially connected to the straight cylindrical section, and a material outlet connected to the bottom of the conical cylindrical section; A flow guiding structure is provided inside the straight section cylinder and located above the material inlet. It is used to perform preliminary condensation of the high-temperature and humid gas separated by the cyclone separation structure from the straw steam explosion material and to discharge the water after preliminary condensation. A condensing heat exchange structure is provided at the upper end of the cyclone straight section cylinder, which is used to perform deep condensation on the humid gas after preliminary condensation treatment and discharge the deeply condensed water through the guide structure. A circulating absorption structure, which is connected to the condensation heat exchange structure, is used to circulate and absorb low-boiling-point organic compounds in the exhaust gas after deep condensation treatment. An anti-blocking conveying structure is connected to the material outlet and is used to receive and convey the wet material discharged from the cyclone separator at an angle upward, while simultaneously allowing the accumulated water in the wet material to drain downward in a timely manner.

[0012] The integrated solid-liquid-gas separation, condensation, and jet conveying equipment for straw steam explosion materials according to the first aspect of this invention has the following advantages: First, it is less prone to clogging, and wet materials are conveyed without clogging: On the one hand, the water that has undergone preliminary condensation at the guide structure and deep condensation at the condensation heat exchange structure falls back to the guide structure and is discharged directly together with the water that has undergone preliminary condensation, avoiding the condensed water dripping downwards into the material in the cyclone separation zone below the guide structure, thus reducing material blockage in the cyclone separation zone; on the other hand, the anti-clogging conveying structure is directly connected to the material outlet and adopts an upward oblique conveying method, so that the water accumulated in the wet material in the anti-clogging conveying structure can be naturally discharged downwards under the action of gravity, preventing blockage. Second, it has a good condensation effect: Through preliminary condensation and deep condensation, the condensation efficiency and condensation effect of high-temperature humid gas can be greatly improved. Third, it has a compact structure and a small footprint: The cyclone separation structure, guide structure, condensation heat exchange structure, circulation absorption structure, and anti-clogging conveying structure are integrated into a single device, with a compact and reasonable structural layout, reducing the number of equipment and connecting pipelines required by the system, and reducing the footprint. Fourth, it reduces the exhaust gas treatment load: After condensation and dehumidification, the exhaust gas directly enters the circulating absorption structure, where low-boiling-point organic compounds (such as methanol) are absorbed and dissolved during the exhaust process, resulting in more complete recovery of organic compounds, reducing the final emission load of the exhaust gas, and making it more environmentally friendly.

[0013] The first aspect of this invention provides an integrated solid-liquid-gas separation, condensation, and jet conveying device for straw steam-explosion materials. This device addresses the characteristics of straw steam-explosion materials during the process, including high temperature, high humidity, high-speed impact, solid-liquid-gas entrainment, easy condensation and water accumulation, and the potential presence of low-boiling-point organic compounds such as methanol in the exhaust gas. By integrating functional modules such as cyclone separation, condensation, liquid drainage, organic matter recycling and absorption, and solid material anti-blocking conveying in the straw steam-explosion material processing process, the device organizes solid separation, liquid condensation and drainage, low-boiling-point organic matter recycling and absorption, and solid material anti-blocking continuous conveying into a continuous processing flow. This creates a synergistic relationship between the processing steps, thereby reducing disordered condensation and secondary water entrainment during material transfer, lowering the exhaust gas treatment load, and improving the stability and continuity of the straw steam-explosion material processing process.

[0014] In some embodiments, the cyclone separation structure further includes a heat insulation layer disposed on the outer circumferential surface of the conical section cylinder.

[0015] In some embodiments, the inner walls of the straight section cylinder and the conical section cylinder are provided with a wear-resistant layer.

[0016] In some embodiments, a hand hole is provided on the straight section of the cylinder and located on the lower side of the flow guiding structure.

[0017] In some embodiments, the flow guiding structure includes a guide plate, a vent pipe, a condenser plate, and a condensate outlet; the guide plate is inclinedly disposed within the straight section of the cylinder and located above the material inlet; the vent pipe is disposed on the guide plate, with its outlet protruding upwards from the upper surface of the guide plate, and its inlet communicating with the lower space of the guide plate; the condenser plate covers the outlet of the vent pipe and has a gap between it and the outlet of the vent pipe; the condensate outlet is located at a low position on the guide plate.

[0018] In some embodiments, the condensation heat exchange structure includes a shell, a cooling water inlet, a cooling water outlet, a heat exchange tube, and a head; the lower end of the shell is connected to the upper end of the straight section of the cylindrical body; the cooling water inlet and the cooling water outlet are respectively connected to the upper and lower sides of the shell, and the inlet and outlet ends of the heat exchange tube are respectively connected to the bottom and top of the shell; the lower end of the head is connected to the upper end of the shell, and the top exhaust port of the head is connected to the circulating absorption structure.

[0019] In some embodiments, the circulating absorption structure includes a water tank, a circulating pump, and a jet structure; the inlet of the circulating pump is connected to the water tank, and the outlet of the circulating pump is connected to the conveying medium inlet of the jet structure; the top exhaust port is connected to the conveyed medium inlet of the jet structure, and the jet outlet of the jet structure is connected to the water tank or a subsequent collection unit.

[0020] In some embodiments, the jet structure includes a connector pipe and a jet pump; one axial end of the connector pipe is connected to the inlet of the conveying medium, and the side of the connector pipe is connected to the inlet of the conveyed medium; the jet pump has an axially connected mixing chamber and a jet outlet; one axial end of the jet pump is connected to the other axial end of the connector pipe.

[0021] In some embodiments, the anti-clogging conveying structure includes an inclined screw conveyor, a discharge port located at the upper end of the screw conveyor, a drain port located at the lower end of the screw conveyor, and a feed port connected between the material outlet and the lower end of the screw conveyor.

[0022] A second aspect of the present invention also proposes a solid-liquid-gas separation and condensation jet conveying method for straw steam explosion materials.

[0023] The method for solid-liquid-gas separation and condensation jet conveying of straw vaporized materials according to a second aspect of the present invention uses the integrated solid-liquid-gas separation and condensation jet conveying equipment for straw vaporized materials according to a first aspect of the present invention for conveying, including: The cyclone separation structure separates the solid and gas of the straw steam explosion material. The separated wet material falls into the anti-blocking conveying structure, and the separated high-temperature and humid gas enters the guiding structure. The anti-blocking conveying structure tilts and conveys the falling wet material upwards, while the water in the wet material is discharged downwards. The high-temperature, humid gas is initially condensed through the flow guiding structure, and the water after initial condensation is discharged. The humid gas after initial condensation enters the condensation heat exchange structure. The humid gas after preliminary condensation treatment is deeply condensed through the condensation heat exchange structure and the water after deep condensation is discharged through the flow guide structure, while the exhaust gas after deep condensation treatment enters the circulation absorption structure. The circulating absorption structure circulates and absorbs low-boiling-point organic compounds from the exhaust gas after deep condensation treatment.

[0024] Since the solid-liquid-gas separation and condensation jet conveying method for straw steam-explosion material in the second aspect of the present invention uses the integrated solid-liquid-gas separation and condensation jet conveying equipment for straw steam-explosion material in the first aspect of the present invention for conveying, the solid-liquid-gas separation and condensation jet conveying method for straw steam-explosion material in the second aspect of the present invention has essentially the same technical effects as the integrated solid-liquid-gas separation and condensation jet conveying equipment for straw steam-explosion material in the first aspect of the present invention, and will not be described again here.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0028] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following is combined Figures 1 to 9 This invention describes an integrated solid-liquid-gas separation, condensation, jet conveying device 1000 and method for straw steam explosion material, based on embodiments of the present invention.

[0030] like Figures 1 to 9 As shown, the integrated solid-liquid-gas separation, condensation, and jet conveying equipment 1000 for straw steam explosion material according to the first aspect of the present invention includes a cyclone separation structure 1, a flow guiding structure 2, a condensation heat exchange structure 3, a circulation absorption structure 4, and an anti-blocking conveying structure 5.

[0031] The cyclone separator 1 includes a straight cylindrical section 101, a conical cylindrical section 102 connected to the lower end of the straight cylindrical section 101, a material inlet 103 tangentially connected to the straight cylindrical section 101, and a material outlet 104 connected to the bottom of the conical cylindrical section 102. The straight cylindrical section 101 and the conical cylindrical section 102 are welded together to form the core cavity of the cyclone separator 1. The high-temperature, high-humidity solid-liquid-gas mixture generated by the straw steam explosion device, i.e., the straw steam explosion material, enters the straight section cylinder 101 tangentially through the material inlet 103. A high-speed rotating flow field is formed in the straight section cylinder 101 and the conical section cylinder 102. Since the density of the wet material is greater than that of the gas, under the action of centrifugal force, inertial force and gravity, the wet material is thrown towards the inner wall surface of the straight section cylinder 101 and the conical section cylinder 102 and moves downward along the inner wall surface of the straight section cylinder 101 and the conical section cylinder 102, and finally falls to the bottom of the conical section cylinder 102 and is discharged through the material outlet 104 to the anti-blocking conveying structure 5. The separated high-temperature humid gas flows upward, thus the separation of the wet material (i.e., the moist solid material) and the high-temperature humid gas of the straw steam explosion material is initially achieved through the cyclone separation structure 1.

[0032] Furthermore, the cone angle of the conical section 102 ranges from 25° to 35°. This cone angle range ensures stable rotation of the cyclone airflow while allowing the separated solid material to fall more smoothly to the material outlet 104, thereby reducing material retention and accumulation in the conical section 102, improving separation efficiency, and reducing the risk of blockage caused by material accumulation. Preferably, the cone angle of the conical section 102 is designed to be 30°, ensuring stable rotation of the cyclone airflow while allowing the separated solid particles to fall more smoothly to the material outlet 104, thereby reducing material retention and accumulation in the conical region, improving separation efficiency, and reducing the risk of blockage caused by material accumulation.

[0033] The inner wall of the cyclone separator 1 can also be protected with a wear-resistant coating, effectively improving its resistance to high-speed wet material erosion. Under conditions such as biomass steam explosion, the material particles have high velocity and great impact force, making the inner wall of the traditional cyclone separator 1 prone to wear. However, by applying a wear-resistant coating, the erosion damage to the wall of the cyclone separator 1 can be significantly reduced, extending its service life, reducing maintenance frequency and replacement costs, thereby improving the long-term operational stability of the equipment.

[0034] The guide structure 2 is located inside the straight section cylinder 101 and above the material inlet 103. It is used to initially condense the high-temperature, humid gas separated from the straw explosion material by the cyclone separator 1 and to discharge the water after initial condensation. The high-temperature, humid gas separated by the cyclone separator 1 flows upward into the guide structure 2. The guide structure 2 serves as the initial condensation zone. When the high-temperature, humid gas from the cyclone separator 1 contacts the guide structure 2, some of the water vapor in the gas undergoes heat exchange, achieving initial condensation and liquefaction. The water after initial condensation is directly collected and discharged under the guidance of the guide structure 2, preventing the condensate from dripping back into the material in the cyclone separation zone below the guide structure 2. The guide structure 2 achieves initial condensation and orderly discharge of water vapor inside the cyclone separator 1, effectively preventing the disorderly accumulation of condensate inside the cyclone separator 1, reducing the moisture content of the separated material, improving the solid-liquid-gas separation effect, and simultaneously reducing the interference of condensate on the flow field of the separation zone, thus reducing the re-entrainment of condensate into the solid material.

[0035] The condensing heat exchange structure 3 is located at the upper end of the cyclone straight section cylinder 101. The humid gas, after preliminary condensation treatment, enters the condensing heat exchange structure 3 for further condensation and is discharged through the guide structure 2. It can be understood that the humid gas, after preliminary condensation treatment, flows upward into the condensing heat exchange structure 3. Through heat exchange, some of the water vapor and low-boiling-point components in the humid gas are further condensed, and the deeply condensed water falls back to the guide structure 2 and is discharged through it.

[0036] The circulating absorption structure 4 is connected to the condensation heat exchange structure 3 and is used to circulate and absorb low-boiling-point organic compounds in the exhaust gas after deep condensation treatment. It can be understood that the exhaust gas after deep condensation treatment flows through the circulating absorption structure 4, and through full contact between the exhaust gas and the absorption medium in the circulating absorption structure 4, such as water or other absorption media, low-boiling-point organic compounds such as methanol in the exhaust gas are absorbed.

[0037] The anti-blocking conveyor structure 5 is connected to the material outlet 104 and is used to receive and obliquely upward convey the wet material discharged from the cyclone separator 1, while simultaneously allowing the accumulated water in the wet material to drain downwards in a timely manner. The anti-blocking conveyor structure 5 adopts an oblique upward conveying method, allowing the accumulated water mixed in the material to drain downwards naturally while conveying the wet material, ensuring that the moisture content of the discharged material is reduced to a minimum and preventing blockage of the channel. The anti-blocking conveyor structure 5 is particularly suitable for conveying straw-based materials containing a certain degree of humidity or a small amount of condensate.

[0038] The working principle of the integrated solid-liquid-gas separation, condensation, jet conveying equipment 1000 for straw steam-explosion materials according to the first aspect of the present invention is as follows: The straw steam explosion material is separated into solid and gas by the cyclone separation structure 1. The separated wet material falls into the anti-clogging conveying structure 5, and the separated high-temperature and humid gas enters the guide structure 2.

[0039] The wet material is tilted upwards and conveyed by the anti-blocking conveyor structure 5, while the water in the wet material is discharged downwards.

[0040] The high-temperature, humid gas is initially condensed through the flow guide structure 2, and the water after initial condensation is discharged. The humid gas after initial condensation enters the condensation heat exchange structure 3.

[0041] The humid gas after preliminary condensation treatment is further condensed through the condensation heat exchange structure 3, and the condensed water is discharged through the guide structure 2. The exhaust gas after deep condensation treatment enters the circulation absorption structure 4. The condensate after condensation through the condensation heat exchange structure 3 is discharged through the guide structure 2. This structural arrangement is more compact and reasonable.

[0042] The low-boiling-point organic compounds in the exhaust gas after deep condensation treatment are absorbed by the circulating absorption structure 4.

[0043] The integrated solid-liquid-gas separation, condensation, and jet conveying equipment 1000 for straw steam explosion materials according to the first aspect of the present invention has the following advantages: First, it is less prone to clogging, and wet materials are conveyed without clogging: On the one hand, the water after preliminary condensation is discharged through the guide structure 2, and the water after deep condensation at the condensation heat exchange structure 3 falls back to the guide structure 2 and is discharged directly together with the water after preliminary condensation, avoiding the condensed water dripping down into the material in the cyclone separation zone below the guide structure 2, thus reducing the material blockage in the cyclone separation zone; on the other hand, the anti-clogging conveying structure 5 is directly connected to the material outlet 104 and adopts an upward oblique conveying method, so that the water accumulated in the wet material in the anti-clogging conveying structure 5 can be discharged naturally downward under the action of gravity, preventing blockage. Second, it has a good condensation effect: Through preliminary condensation and deep condensation, the condensation efficiency and condensation effect of high-temperature humid gas can be greatly improved. Third, it has a compact structure and a small footprint: The cyclone separation structure 1, guide structure 2, condensation heat exchange structure 3, circulation absorption structure 4, and anti-clogging conveying structure 5 are integrated into a single device, with a compact and reasonable structural layout, reducing the number of equipment and connecting pipelines required by the system, and reducing the footprint. Fourth, it reduces the exhaust gas treatment load: the exhaust gas after condensation and dehumidification directly enters the circulating absorption structure 4, where low-boiling-point organic matter (such as methanol) is absorbed and dissolved during the exhaust process, resulting in more complete recovery of organic matter, reducing the final emission load of the exhaust gas, and making it more environmentally friendly.

[0044] The first embodiment of the present invention provides an integrated solid-liquid-gas separation, condensation, and jet conveying device 1000 for straw steam-explosion materials. This device addresses the characteristics of straw steam-explosion materials during the process, including high temperature, high humidity, high-speed impact, solid-liquid-gas entrainment, easy condensation and water accumulation, and the potential presence of low-boiling-point organic compounds such as methanol in the exhaust gas. By integrating functional modules such as cyclone separation, condensation, liquid drainage, organic matter recycling and absorption, and solid material anti-blocking conveying in the straw steam-explosion material processing process, the device organizes solid separation, liquid condensation and drainage, low-boiling-point organic matter recycling and absorption, and solid material anti-blocking continuous conveying into a continuous processing flow. This creates a synergistic relationship between the processing steps, thereby reducing disordered condensation and secondary water entrainment during material transfer, lowering the exhaust gas treatment load, and improving the stability and continuity of the straw steam-explosion material processing process.

[0045] The integrated solid-liquid-gas separation, condensation, and jet conveying equipment 1000 for straw steam-exploded materials according to the first aspect of the present invention is not merely a structural improvement of a single cyclone separator. Instead, it achieves continuous, compact, low-water-accumulation, and low-clogging treatment of straw steam-exploded materials by coordinating the flow path, condensation path, liquid discharge path, jet suction path, circulation absorption path, and solid conveying path of the solid-liquid-gas mixture after steam explosion. This allows the mixture after explosion to sequentially complete cyclone separation, preliminary condensation, deep condensation, condensate drainage, exhaust gas jet suction, circulation absorption of low-boiling-point organic matter in the exhaust gas, and continuous solid material conveying without clogging in the same processing process.

[0046] In some embodiments, the cyclone separator 1 further includes a heat insulation layer 105, which is disposed on the outer circumferential surface of the conical section 102. The heat insulation layer 105 is used to prevent condensation from being trapped in the material separated by the cyclone separator 1. Through the heat insulation effect of the heat insulation layer 105, a large amount of condensate can be prevented from condensing prematurely in the cyclone separator 1, reducing the possibility of condensation being trapped in the solid material, thereby maintaining the dryness of the material separated by the cyclone separator 1 and improving the material quality. A jacket structure is provided in the equipment structure to prevent condensation from being trapped in the separated material. Through the heat insulation effect of the jacket structure, a large amount of condensate can be prevented from being generated, thereby maintaining the dryness of the separated material, improving the material quality, and reducing transportation and subsequent processing problems caused by moisture trapping.

[0047] In some embodiments, the insulation layer 105 is a jacket, with a jacket steam inlet 1051 at the upper part and a jacket condensate outlet 1052 at the lower part. In this way, steam can enter the jacket through the jacket steam inlet 1051 to insulate the cyclone separator 1, thereby reducing the premature condensation of gas within the cyclone separator 1, thus reducing the possibility of solid materials carrying condensate and forming a slurry, and preventing blockage.

[0048] In some embodiments, the inner walls of the straight section cylinder 101 and the conical section cylinder 102 are provided with a wear-resistant layer. The wear-resistant coating protects the straight section cylinder 101 and the conical section cylinder 102, effectively improving their resistance to high-speed particle erosion. In conditions such as biomass steam explosion, the material particles have high velocity and great impact force, making the inner walls of traditional equipment prone to wear. However, by providing a wear-resistant coating, the erosion damage to the inner walls of the straight section cylinder 101 and the conical section cylinder 102 caused by particles can be significantly reduced, extending the equipment's service life, reducing maintenance frequency and replacement costs, thereby improving the long-term operational stability of the equipment.

[0049] In some embodiments, a handhole 106 is provided on the straight section cylinder 101 and located below the flow guide structure 2. Cleaning fluid is introduced into the straight section cylinder 101 through the handhole 106. During equipment operation or maintenance shutdown, the inside of the cyclone separation structure 1 and the anti-clogging conveying structure 5 can be cleaned and maintained through the handhole 106, reducing the adhesion, deposition, and scaling of residual straw materials. At the same time, it effectively removes residual materials adhering to the inner wall and internal structure of the cyclone separation structure 1. The handhole 106 significantly improves the convenience of equipment cleaning, reduces the workload of disassembly and cleaning during shutdown, improves equipment maintenance efficiency, and helps maintain the stability of the internal flow field of the integrated solid-liquid-gas separation, condensation, and jet conveying equipment 1000 for straw vaporization and explosion.

[0050] In some embodiments, the flow guiding structure 2 includes a guide plate 201, a vent pipe 202, a condenser plate 203, and a condensate outlet 204. The guide plate 201 is inclinedly disposed within the straight section cylinder 101 and located above the material inlet 103. The vent pipe 202 is disposed on the guide plate 201, with its outlet protruding upwards from the upper surface of the guide plate 201, and its inlet communicating with the lower space of the guide plate 201. The condenser plate 203 covers the outlet of the vent pipe 202 and has a gap with it. The condensate outlet 204 is located at a low position on the guide plate 201. The guide plate 201 is inclinedly disposed within the straight section cylinder 101 and located above the material inlet 103, thus dividing the internal space of the straight section cylinder 101 into a lower cyclone separation zone and an upper preliminary condensation zone.

[0051] The working principle of the flow guiding structure 2 is as follows: the high-temperature, humid gas separated by the cyclone separator 1 flows sequentially through the vent pipe 202, the side opening between the condenser plate 203 and the flow guiding plate 201, and then overflows to the surrounding area, filling the upper condensation zone. Water vapor in the high-temperature, humid gas condenses upon contact with the condenser plate 203. The initially condensed water flows along the flow guiding plate 201 to a lower position and is finally discharged from the equipment through the condensate outlet 204. This structural design allows for the initial condensation and orderly discharge of water vapor inside the cyclone separator, effectively preventing the disorderly accumulation of condensate inside the equipment, thereby reducing the moisture content of the separated material, improving the solid-liquid-gas separation effect, and reducing the interference of condensate on the flow field of the separation area.

[0052] Specifically, the guide plate 201 has a through hole, and the vent pipe 202 is installed in the through hole.

[0053] In some embodiments, a condenser is also provided above the guide plate 201, and the space between the guide plate 201 and the condenser is designed as the lower tube side, allowing the gas after preliminary separation to further enter the condensation area. Under the cooling effect of the condenser, the low-boiling-point waste gas and some water vapor in the gas condense and form liquid. The condensate drips onto the guide plate 201 and the condenser plate 203 and is discharged from the equipment through the same condensate drain outlet. By integrating the condenser with the cyclone separation structure 1, solid-liquid-gas separation and gas condensation treatment can be achieved in the same equipment. This not only reduces the floor space and piping complexity caused by multiple devices connected in series in traditional processes, but also improves the overall operating efficiency of the system and makes the equipment layout more compact and reasonable.

[0054] In some embodiments, the condenser plate 203 is arranged at an angle, and the angle of the condenser plate 203 is consistent with the angle of the guide plate 201. This arrangement is to allow the condensate formed on the condenser plate 203 to slide down the inclined surface onto the guide plate 201 and be discharged through the same condensate outlet 204, making the structural arrangement more compact and reasonable.

[0055] In some embodiments, the condenser plate 203 is supported on the baffle plate 201, the straight section cylinder 101, or the vent pipe 202 by a support frame 205. The support frame 205 provides a stable and rigid connection for the condenser plate 203.

[0056] In some embodiments, the condensation heat exchange structure 3 includes a shell 301, a cooling water inlet 302, a cooling water outlet 303, a heat exchange tube 304, and a head 305; the lower end of the shell 301 is connected to the upper end of the straight section cylinder 101; the cooling water inlet 302 and the cooling water outlet 303 are respectively connected to the lower and upper sides of the shell 301, the inlet end and the outlet end of the heat exchange tube 304 are respectively connected to the bottom and the top of the shell 301; the lower end of the head 305 is connected to the upper end of the shell 301, and the top exhaust port 3051 of the head 305 is connected to the circulation absorption structure 4.

[0057] The working principle of the condensation heat exchange structure 3 is as follows: the humid gas, after being initially condensed by the guide plate 201, enters the heat exchange tube 304 from the inlet end of the heat exchange tube 304. At the same time, cooling water is injected from the cooling water inlet 302 on the lower side of the shell 301, flows upward and is discharged from the cooling water outlet 303 on the upper side. Thus, the humid gas after the initial condensation treatment is deeply condensed in the heat exchange tube 304 through indirect heat exchange. The water after deep condensation falls back to the guide structure 2 and is discharged under the action of gravity. The exhaust gas after deep condensation treatment rises to the end cap 305 and is finally transported to the circulation absorption structure 4 for subsequent treatment through the top exhaust port 3051.

[0058] In some embodiments, the circulating absorption structure 4 includes a water tank 401, a circulating pump 402, and a jet structure 403; the inlet of the circulating pump 402 is connected to the water tank 401, and the outlet of the circulating pump 402 is connected to the conveying medium inlet 404 of the jet structure 403; the top exhaust port 3051 is connected to the conveyed medium inlet 405 of the jet structure 403, and the jet outlet 4034 of the jet structure 403 is connected to the water tank 401 or a subsequent collection unit. The water tank 401 is used to store water or other absorbent media; the circulating pump 402 is used to pressurize and convey the water or other absorbent media in the water tank 401 to the conveying medium inlet 404 of the jet structure 403.

[0059] The working principle of the circulating absorption structure 4 is as follows: After the circulating pump 402 starts, the water or other absorption medium in the water tank 401 is pressurized and transported to the conveying medium inlet 404 of the jet structure 403. The high-speed jet ejected from the conveying medium inlet 404 forms a jet negative pressure suction effect in the jet structure 403, which quickly draws the exhaust gas from the top exhaust port 3051 into the jet structure 403 through the conveying medium inlet 405. The absorption medium and the exhaust gas fully contact and mix and react and absorb inside the jet structure 403. The gas-liquid mixture finally formed is discharged from the spray outlet 4034 and returned to the water tank 401. In this way, the exhaust gas is drawn in and the low boiling point organic matter is recovered. This can avoid gas retention and backflow, reduce the subsequent exhaust gas treatment load, and improve the environmental protection and compactness of the system operation. In some embodiments, the jet structure 403 includes a connector pipe 4031 and a jet pump 4032; one axial end of the connector pipe 4031 is connected to the inlet 404 of the conveying medium, and the side of the connector pipe 4031 is connected to the inlet 405 of the conveyed medium; the jet pump 4032 is provided with an axially connected mixing chamber 4033 and a jet outlet 4034; one axial end of the jet pump 4032 is connected to the other axial end of the connector pipe 4031. The absorbent medium flows into the connector pipe 4031 axially, while the exhaust gas enters from the side of the connector pipe 4031, which is a reasonable design. The circulating pump 402 delivers water or other absorbent medium from the water tank 401 to the jet pump 4032, causing the absorbent medium to flow at high speed and form a negative pressure in the jet pump 4032, thereby continuously drawing the condensed and heat-exchanged exhaust gas into the jet pump 4032. The condensed exhaust gas and the absorbent medium are fully mixed and contacted in the jet pump 4032, which can absorb and recover low-boiling-point organic compounds such as methanol in the condensed exhaust gas. This not only enhances the exhaust gas transport capacity and avoids gas stagnation and backflow, but also reduces the subsequent exhaust gas treatment load, improving the environmental friendliness and compactness of the system operation.

[0060] In some embodiments, the anti-clogging conveying structure 5 includes an inclined screw conveyor 501, a discharge port 502 located at the upper end of the screw conveyor 501, a drain port 503 located at the lower end of the screw conveyor 501, and a feed port 504 connecting the material outlet 104 and the lower end of the screw conveyor 501. Solid material discharged from the material outlet 104 enters the inclined screw conveyor 501 through the feed port 504. During the rotation and propulsion of the screw, the material is subjected to gravity, and the water trapped inside it permeates downward and is discharged in time through the drain port 503 at the lower end, achieving solid-liquid separation. The dehydrated material is continuously conveyed obliquely upward to the discharge port 502 at the upper end for discharge; thus, continuous conveying and re-dehydration of solid material are achieved.

[0061] In some embodiments, the screw conveyor 501 is a twin-screw conveyor or a single-screw conveyor. The twin-screw conveyor includes a left screw 5013 and a right screw 5014. The single-screw conveyor has a simpler structure. Since the solid material after straw steaming and popping may contain a small amount of condensate, it has a certain degree of humidity and adhesion, easily forming bridging, accumulation, or agglomeration at the material outlet 104 and inlet 504. In the twin-screw conveyor, the left screw 5013 and the right screw 5014 are arranged opposite each other and rotate synchronously in opposite directions, agitating, breaking up, loosening, and continuously pushing the wet material falling into the anti-blocking conveying structure 5, preventing bridging and accumulation of material at the material outlet 104 and inlet 504. The twin-screw conveyor reduces the risk of jamming and blockage, significantly improving the continuity of material discharge.

[0062] In some embodiments, an upper anti-blocking component 5011 and a lower anti-blocking component 5012 are provided at the gap between the two screws of the twin-screw conveying device. Specifically, both the upper anti-blocking component 5011 and the lower anti-blocking component 5012 are angle steel. The upper anti-blocking component 5011 and the lower anti-blocking component 5012 fill and guide the area where material easily accumulates between the two screws, reducing material retention in the gap between the left screw 5013 and the right screw 5014 and at the bottom of the anti-blocking conveying structure 5, thereby reducing the risk of wet material agglomeration, bridging, blockage, and backflow, and improving the continuous discharge capacity and operational reliability of the device.

[0063] Below, as Figures 1 to 9 As shown, a detailed description is provided of an integrated solid-liquid-gas separation, condensation, and jet conveying device 1000 for straw vaporization and explosion materials, based on a specific embodiment of the present invention: It includes a bottom cyclone separation structure 1, a middle flow guiding structure 2, a top condensation heat exchange structure 3, a jet structure 403 set at the exhaust end, a circulation absorption structure 4 that cooperates with the jet structure 403, and an anti-blocking conveying structure 5 set at the discharge end.

[0064] The cyclone separator 1 consists of a conical section cylinder 102, a jacket, a material outlet 104, a material inlet 103, a jacket steam inlet 1051, and a jacket condensate outlet 1052.

[0065] The flow guiding structure 2 consists of a straight section cylinder 101, a condensate outlet 204, a condensate plate 203, a support frame 205, a flow guiding plate 201, and a vent pipe 202.

[0066] The condensing heat exchange structure 3 consists of a top exhaust port 3051, an elliptical head 305, a shell 301, a cooling water inlet 302, a cooling water outlet 303, and a heat exchange tube 304.

[0067] The jet structure 403 located at the exhaust end includes a conveying medium inlet 404, a conveyed medium inlet 405, a jet outlet 4034, and a jet pump 4032.

[0068] The circulating absorption structure 4 includes a water tank 401, a circulating pump 402, and a circulating pipeline 406 connecting the water tank 401, the circulating pump 402, and the conveying medium inlet 404. The circulating pump 402 is used to pressurize and convey water or other absorption media in the water tank 401 to the conveying medium inlet 404 of the jet pump 4032. The anti-blocking conveying structure 5 installed at the discharge end includes a sliding bearing and end cover 505, a left screw 5013, a right screw 5014, an inlet 504, an upper angle steel, a conveying structure housing 506, a motor 507, a motor-side bearing and end cover 508, an outlet 502, and a lower angle steel.

[0069] The conical section 102 and the straight section 101 are welded together to form the core cavity of the cyclone separator structure 1. A material outlet 104 is located below, and a material inlet 103 is provided tangentially along the straight section 101. A hand hole 106 is designed on the straight section 101. The cyclone separator structure 1 and the guide structure 2 are separated by a guide plate 201 and connected by a vent pipe 202. The guide plate 201 is welded obliquely to the shell 301 of the straight section 101 at a 5-degree angle. A condenser plate 203 is installed on the vent pipe 202. The condenser plate 203 is welded and fixed to the guide plate 201 by three support frames 205. A condensate outlet 204 is opened in the lower section of the straight section 101 of the guide plate 201. The flow guiding structure 2 is connected to the condensing heat exchange structure 3 via a flange connection. That is, the cavity at the flow guiding structure 2 can simultaneously be considered as the tube side of the condensing heat exchange structure 3, connected by several heat exchange tubes 304 leading to the top end cap 305 of the condensing heat exchange structure 3. The end cap 305 is also connected to the shell 301 via a flange connection. The top of the end cap 305 has a top vent 3051 connected to subsequent pipelines and downstream processing equipment (not shown in the figure). The lower part of the shell 301 has a cooling water inlet 302, and the upper part has a cooling water outlet 303. The jet structure 403 is connected to the top vent 3051 of the condensing heat exchange structure 3 via a pipe or flange. The inlet 405 of the transported medium in the jet structure 403 is connected to the top vent 3051, the transported medium inlet 404 is connected to the outlet of the circulating pump 402 of the circulating absorption structure 4, and the jet outlet 4034 is connected to the water tank 401 or a subsequent collection unit (not shown in the figure). The circulating pump 402 pressurizes and transports water or other absorbent media from the water tank 401 to the conveying medium inlet 404. The absorbent media flows at high speed in the jet pump 4032 and forms a jet negative pressure suction effect, thereby drawing in the exhaust gas after condensation and heat exchange through the conveying medium inlet 405. The drawn-in exhaust gas mixes and contacts with the absorbent media in the jet pump 4032. Low-boiling-point organic compounds such as methanol in the exhaust gas are absorbed by the absorbent media. The resulting mixed medium returns to the water tank 401 or enters the subsequent collection unit through the jet outlet 4034, realizing exhaust gas suction, gas-liquid mixing, and organic matter recycling absorption. The anti-clogging conveying structure 5 is equipped with a left screw 5013 and a right screw 5014. The two screws are arranged side by side with opposite screw directions and are driven synchronously by a motor 507 to continuously convey solid straw material falling from the material outlet 104 into the feed inlet 504 to the discharge outlet 502. Because the solid material after straw explosion may contain a small amount of condensate, it has a certain degree of humidity and adhesion, and is prone to bridging, accumulation or clumping at the feed inlet 504, screw gap and bottom of shell 301.In this embodiment, the relative arrangement of the left screw 5013 and the right screw 5014 allows the material entering the anti-blocking conveying structure 5 to be continuously loosened and conveyed towards the discharge port under the stirring, shearing, and propulsion action of the two screws. At the same time, upper and lower angle steels are set in the gap between the two screws to fill the area where material easily accumulates and to guide the material, reducing the retention of material in the screw gap and the bottom of the shell 301. This reduces the risk of wet material agglomeration, blockage, and backflow, and improves the continuous discharge capacity and operational stability of the anti-blocking conveying structure 5.

[0070] The following describes in detail a method for solid-liquid-gas separation, condensation, and jet conveying of straw-based materials using a specific embodiment of the present invention: The straw ejected from the upstream retainer and the reaction gas products form a high-temperature and high-humidity solid-liquid-gas mixture. The mixture enters the straight section cylinder 101 tangentially through the material inlet 103 and forms a rotating flow field inside the cyclone separation structure 1.

[0071] Under the influence of the rotating flow field, the denser solid straw powder moves towards the separator wall and, under the action of gravity, moves downward along the straight section cylinder 101 and the conical section cylinder 102, eventually being discharged from the material outlet 104. The solid straw powder entering the material outlet 104 falls into the anti-clogging conveying structure 5 and is continuously conveyed to the discharge port 502 by the combined action of the left screw 5013 and the right screw 5014. Since the straw powder may contain a small amount of condensate, the material has a certain degree of moisture and adhesion. During rotation, the left screw 5013 and the right screw 5014 can agitate, break up arches, and propel the material, reducing bridging and accumulation at the inlet 504. The upper and lower angle steels can fill and guide the gap between the two screws, reducing material retention in the screw gaps and at the bottom of the conveying structure shell 506, thereby reducing the risk of conveying blockage.

[0072] The less dense gaseous products and entrained droplets flow towards the upper part of the equipment and enter the guide structure 2 through the vent pipe 202. During the ascent, the gas comes into contact with the condenser plate 203, and some water vapor undergoes preliminary condensation. The resulting condensate falls onto the inclined guide plate 201 and collects along the guide plate 201 to a lower position, and is finally discharged from the equipment through the condensate outlet 204.

[0073] The gas, after initial condensation, continues to enter the condensation heat exchange structure 3. Cooling water enters the shell 301 through the cooling water inlet 302 and flows out through the cooling water outlet 303. During the flow of the gas in the heat exchange tube 304, it indirectly exchanges heat with the cooling water in the shell 301, causing some of the water vapor and low-boiling-point organic components to condense further. The resulting condensate falls back to the guide structure 2 and is discharged through the condensate outlet 204.

[0074] After condensation and heat exchange, the exhaust gas enters the jet structure 403 through the top exhaust port 3051. Water or other absorbent media in the water tank 401, pressurized by the circulation pump 402, is transported through the circulation pipeline 406 to the transport medium inlet 404 of the jet pump 4032, forming a high-speed jet within the jet pump 4032. The high-speed flowing absorbent media creates a negative pressure suction effect at the transport medium inlet 405, continuously drawing the exhaust gas discharged from the top exhaust port 3051 into the jet pump 4032. The exhaust gas and absorbent media are thoroughly mixed and contacted within the jet pump 4032, allowing low-boiling-point organic compounds such as methanol in the exhaust gas to be absorbed by the absorbent media. The resulting mixed medium returns to the water tank 401 or enters the subsequent collection unit through the jet outlet 4034, thus achieving exhaust gas jet suction and organic matter recycling absorption.

[0075] Meanwhile, steam can enter the jacket through the jacket steam inlet 1051 to insulate the cyclone separator 1, thereby reducing the premature condensation of gas in the solid material discharge area and thus reducing the possibility of solid material carrying condensate and forming a slurry. During equipment operation or shutdown maintenance, the inside of the straight section cylinder 101 and the conical section cylinder 102 can be cleaned and maintained through the handhole 106 to reduce the adhesion, deposition, and scaling of straw residue.

[0076] A second aspect of the present invention also proposes a solid-liquid-gas separation and condensation jet conveying method for straw steam explosion materials.

[0077] According to a second aspect of the present invention, a method for solid-liquid-gas separation, condensation, and jet conveying of straw vaporized materials is used, employing an integrated solid-liquid-gas separation, condensation, and jet conveying device 1000 according to a first aspect of the present invention for conveying, including: The straw steam explosion material is separated into solid and gas by the cyclone separation structure 1. The separated wet material falls into the anti-clogging conveying structure 5, and the separated high-temperature and humid gas enters the guide structure 2.

[0078] The wet material is tilted upwards and conveyed by the anti-blocking conveyor structure 5, while the water in the wet material is discharged downwards.

[0079] The high-temperature, humid gas is initially condensed through the flow guide structure 2, and the water after initial condensation is discharged. The humid gas after initial condensation enters the condensation heat exchange structure 3.

[0080] The humid gas after preliminary condensation treatment is further condensed through the condensation heat exchange structure 3 and the water after deep condensation is discharged through the guide structure 2, while the exhaust gas after deep condensation treatment enters the circulation absorption structure 4.

[0081] The low-boiling-point organic compounds in the exhaust gas after deep condensation treatment are absorbed through the circulating absorption structure 4.

[0082] Since the solid-liquid-gas separation and condensation jet conveying method for straw steam-explosion materials in the second aspect of the present invention uses the integrated solid-liquid-gas separation and condensation jet conveying equipment 1000 for straw steam-explosion materials in the first aspect of the present invention for conveying, the solid-liquid-gas separation and condensation jet conveying method for straw steam-explosion materials in the second aspect of the present invention has essentially the same technical effects as the integrated solid-liquid-gas separation and condensation jet conveying equipment 1000 for straw steam-explosion materials in the first aspect of the present invention, and will not be described again here.

[0083] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
