Technical Field
[0001] This utility model belongs to the technical field of steam explosion reaction chambers, specifically a straw steam explosion pretreatment reaction chamber. Background Technology
[0002] The straw steam explosion pretreatment reaction chamber is the core equipment for realizing steam explosion (steam explosion) technology. Its working principle involves treating straw with high-temperature, high-pressure steam and then instantly depressurizing it, thereby destroying the lignocellulose structure and improving the efficiency of subsequent enzymatic hydrolysis or fermentation. Therefore, instantaneous depressurization is a crucial step in the reaction chamber. Existing reaction chambers typically achieve depressurization by opening valves, but even with valves fully opened, there is still a delay of several seconds, which is insufficient to achieve adequate instantaneous depressurization. Therefore, this application proposes a straw steam explosion pretreatment reaction chamber to improve upon existing reaction chambers. Summary of the Invention
[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a straw steam explosion pretreatment reaction chamber, which effectively solves the problem that the existing steam explosion reaction chamber is not convenient to achieve instantaneous depressurization.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a straw steam explosion pretreatment reaction chamber, including a support base, a support frame one and a support frame two are fixedly installed at one end of the top of the support base, a reaction chamber body is installed through the interior of the support frame one and the support frame two, a steam inlet pipe is installed at one end of the reaction chamber body, a controller is fixedly installed on the side of the support frame one, a ring electromagnet is fixedly installed at one end of the support frame two, an impact-resistant support mechanism is fixedly installed at the top of the support base away from the support frame one, a plurality of limiting support rods are fixedly installed between the impact-resistant support mechanism and the support frame two, and a sealing component matching the reaction chamber body is slidably sleeved on the limiting support rods; The impact-resistant support mechanism consists of an L-shaped support base, a hydraulic damper, and a spring buffer assembly. The L-shaped support base is fixedly connected to the top of the support base. The hydraulic damper passes through the L-shaped support base and is fixedly connected to it. The spring buffer assembly slides through the L-shaped support base and matches the hydraulic damper.
[0005] Preferably, the spring buffer assembly consists of two limiting rods, two buffer springs, a metal plate, and a rubber pad.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0012] Depend on Figures 1 to 5 The present invention discloses a straw steam explosion pretreatment reaction chamber, comprising a support base 1, a support frame 2 and a support frame 3 fixedly mounted on one end of the top of the support base 1, a reaction chamber body 4 penetrating inside the support frame 2 and the support frame 3, a steam inlet pipe 5 mounted on one end of the reaction chamber body 4, a controller 6 fixedly mounted on the side of the support frame 2, a ring electromagnet 7 fixedly mounted on one end of the support frame 3, an impact-resistant support mechanism 8 fixedly mounted on the top of the support base 1 away from the support frame 2, a plurality of limiting support rods 9 fixedly mounted between the impact-resistant support mechanism 8 and the support frame 3, and a sealing component 10 matching the reaction chamber body 4 slidably mounted on the limiting support rods 9; During steam explosion treatment, straw is placed inside the reaction chamber 4, and then the reaction chamber 4 is sealed by the sealing component 10. The annular electromagnet 7 magnetically limits the sealing component 10. The steam inlet pipe 5 is connected to the steam engine to supply steam to the inside of the reaction chamber 4. When the steam pressure inside the reaction chamber 4 reaches the specified value, the annular electromagnet 7 is de-energized, contacting the magnetic limit of the sealing component 10. The steam pressure inside the reaction chamber 4 pushes the sealing component 10, causing the sealing component 10 to separate from the reaction chamber 4 instantly, thereby achieving instantaneous pressure relief and improving the treatment effect of straw. The impact-resistant support mechanism 8 can buffer and protect the sealing component 10. The impact-resistant support mechanism 8 consists of an L-shaped support base 11, a hydraulic damper 12, and a spring buffer assembly 13. The L-shaped support base 11 is fixedly connected to the top of the support base 1. The hydraulic damper 12 passes through the L-shaped support base 11 and is fixedly connected to it. The spring buffer assembly 13 slides through the L-shaped support base 11 and matches the hydraulic damper 12. The spring buffer assembly 13 consists of two limiting rods 14, two buffer springs 15, a metal plate 16, and a rubber pad 17. The limiting rods 14 slide through the L-shaped support base 11. The metal plate 16 is fixedly connected to one end of the limiting rods 14. The buffer springs 15 are sleeved on the limiting rods 14 and located between the L-shaped support base 11 and the metal plate 16. The rubber pad 17 is fixedly connected to the end of the metal plate 16 away from the limiting rods 14. After the sealing component 10 separates from the reaction chamber 4, it first impacts the rubber pad 17, which provides primary buffering. The buffer spring 15 provides secondary buffering, reducing the impact force of the sealing component 10. The hydraulic damper 12 provides damping buffering, reducing the rebound speed of the sealing component 10. The sealing assembly 10 consists of an iron-nickel alloy sealing plate 18, several limiting sleeves 19, a sealing head 20, and a sealing gasket 21. The limiting sleeves 19 are fixedly connected to the arc-shaped outer surface of the iron-nickel alloy sealing plate 18 and slidably sleeved on the limiting support rod 9. The sealing head 20 is fixedly connected to one end of the iron-nickel alloy sealing plate 18 and slidably connected to one end inside the reaction chamber 4. The sealing gasket 21 is fixedly connected to the end of the limiting sleeve 19 away from the iron-nickel alloy sealing plate 18. The iron-nickel alloy sealing plate 18 can be magnetically attracted to the annular electromagnet 7 and has rust resistance. The sealing head 20 can extend into the interior of the reaction chamber 4 to reduce the rate at which steam heat energy is transferred to the support frame 2 3 and the annular electromagnet 7, thereby preventing the annular electromagnet 7 from being affected by heat and thus preventing the magnetic attraction effect from being affected. The sealing gasket 21 fits against the inner wall of the reaction chamber 4, which can improve the sealing effect. The top of the reaction chamber 4 is equipped with a pressure relief valve 22, a pressure sensor 23, and a thermocouple 24. The pressure relief valve 22 can automatically release pressure when the steam pressure exceeds the threshold, thereby improving safety. The pressure sensor 23 can monitor the pressure, and the thermocouple 24 can monitor the temperature.
[0013] In operation, the system is equipped with a reaction chamber, steam inlet pipe, annular electromagnet, limit support rod, sealing assembly, and impact-resistant support mechanism to achieve steam explosion treatment of straw. After the steam explosion treatment is completed, the limit on the sealing assembly can be released by controlling the annular electromagnet to be instantly de-energized. The high-pressure steam inside the reaction chamber is used to push the sealing assembly, thereby achieving instantaneous pressure relief and improving the treatment effect of straw. By setting up an L-shaped support base, hydraulic damper, and a spring buffer assembly consisting of two limit rods, two buffer springs, a metal plate, and a rubber pad, the sealing assembly can be buffered during the pressure relief process, reducing the impact force of the sealing assembly.
