Description

Technical Field

[0001] This utility model relates to the field of steam explosion technology, specifically to experimental steam explosion equipment. Background Technology

[0002] Steam explosion, also known as vapor explosion, is a technology that uses the principle of steam catapults to achieve an explosive process for the pretreatment of biomass. Its essence lies in the instantaneous release of steam molecules that have penetrated the plant tissue, converting the steam's internal energy into mechanical energy which acts on the intercellular layers of the biomass tissue, thereby decomposing the raw materials with relatively little energy. Because it avoids the secondary pollution problems of chemical treatment and solves the low efficiency problem of biological treatment, it is the most promising pretreatment technology in the field of biomass conversion.

[0003] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0004] First, since there are many types of biomass raw materials, it is necessary to conduct experiments to verify whether they are suitable for steam explosion treatment. If production equipment is used directly, the equipment is large, which leads to time and material consumption, high cost and low efficiency.

[0005] Secondly, because the explosion relief diameters vary for different materials and quantities, existing production equipment cannot accommodate changes in the explosion relief diameter at any time, affecting the accuracy of material explosion tests.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an experimental steam explosion device. This addresses the problems of traditional technologies where the suitability of steam explosion for various biomass raw materials requires experimental verification, leading to time-consuming, material-intensive, costly, and inefficient production equipment due to its large size. Furthermore, the varying vent diameters for different materials and quantities mean that existing production equipment cannot readily adapt to changes in vent diameter, affecting the accuracy of material explosion experiments.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0017] As an optimized solution, the explosion relief valve is a quick-opening pneumatic ball valve.

[0018] As an optimized solution, the lower end of the heating device is supported on a device bracket.
