Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically to 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. The most critical and challenging aspect is how to achieve the instantaneous release of steam using the release valve on the equipment.

[0003] A prior art patent, CN120100912A, discloses a solution comprising a cylindrical valve body, a valve cover oscillating on its outer wall to open and close its release port, and a plurality of oscillating claws surrounding the outer wall of the valve body, with a mating inclined surface between the contact surfaces of the claws and the valve cover. This invention solves the problems of conventional detonation cylinders being limited by their structure, making sealing and venting time requirements difficult to address; and ball valves suffering from severe wear and difficulty in scaling up in practical applications, thus preventing their use in large-scale steam explosion equipment.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects: First, currently, one type of venting device for steam explosion equipment is the detonation cylinder. However, although the detonation cylinder can achieve automated production in actual applications, it is difficult to solve the sealing problem and venting time requirements due to structural limitations.

[0005] Secondly, there is the ball valve. However, ball valves suffer from severe wear and tear in actual applications, making replacement expensive. Furthermore, it is difficult to produce ball valves larger than DN200 that can meet the discharge time requirements, thus limiting their size.

[0006] Third, during the explosion and gas release process, the gas will contain some materials, causing the materials to be sprayed into the working environment. The rapid gas rush will also cause a lot of noise, affecting the working environment.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the shortcomings of the existing technology, this utility model solves the problem that in the process of venting and releasing gas in traditional blasting equipment, the gas will contain some material, causing the material to be sprayed into the working environment, and the rapid gas rushing out will cause a lot of noise, affecting the working environment.

[0009] To solve the above problems, this utility model provides the following technical solution: A steam explosion device includes an explosion vessel body, the explosion vessel body is connected to a relief valve, and a connecting section is horizontally provided on the outer wall of the buffer cylinder to communicate with its inner cavity. The steam outlet end of the relief valve is connected to the connecting section.

[0010] As an optimized solution, the upper end of the buffer cylinder is open, and a venting hood is provided above the buffer cylinder, forming a venting channel between the lower end face of the venting hood and the upper port of the buffer cylinder.

[0011] As an optimized solution, the vent includes a cone-shaped hood that tapers downwards.

[0012] As an optimized solution, several support rods are vertically fixed to the outer wall of the buffer cylinder, and the upper end of the support rods is fixed to the lower end face of the air diffuser.

[0013] As an optimized solution, the lower end of the buffer cylinder is fixed with a material collection section that tapers downwards.

[0014] As an optimized solution, a discharge valve is connected to the lower port of the collecting section.

[0015] As an optimized solution, the lower end of the blasting vessel body is fixedly connected to a drain valve port that communicates with its internal cavity.

[0016] As an optimized solution, several high-temperature steam inlets are connected in parallel on the side wall of the main body of the blasting vessel.

[0017] As an optimized solution, a manual exhaust valve is connected to the side wall of the blasting vessel body.

[0018] As an optimized solution, the main body of the blasting vessel is provided with a loading and unloading port, and a valve cover is provided at the loading and unloading port.

[0019] Compared with the prior art, the beneficial effects of this utility model are: By connecting the steam outlet end of the vent valve to the connecting section buffer cylinder, some of the material mixed in the vented gas can be recovered, preventing the gas from rushing out directly and spraying the material into the working environment. The sprayed material is collected by the bottom collection section, and the material is discharged by opening the discharge valve, which is convenient and quick. Since the rapid expulsion of gas will generate a lot of noise, the buffer cylinder can also play a role in reducing noise. The gas is discharged through the cone-shaped gas diffuser at the top. It not only achieves instantaneous release and improves the product quality of steam explosion equipment, but also greatly extends its service life. Moreover, it is convenient and inexpensive to maintain and replace in the later stages. Attached Figure Description

The steam outlet end of the relief valve 7 is connected to the connecting section 8.

[0025] The upper end of the buffer cylinder 2 is open, and a vent hood 11 is provided above the buffer cylinder 2, forming a venting channel between the lower end face of the vent hood 11 and the upper port of the buffer cylinder 2.

[0027] Several support rods 12 are vertically fixed to the outer wall of the buffer cylinder 2, and the upper end of the support rods 12 is fixed to the lower end face of the air diffuser 11.

[0028] The lower end of the buffer cylinder 2 is fixed with a material collection section 9 that is arranged in a downwardly tapering manner.

[0029] The lower port of the material collection section 9 is connected to a discharge valve 10.

[0030] The lower end of the blasting vessel body 1 is fixed with a drain valve port 6 that connects to its inner cavity.

[0031] Several high-temperature steam inlets 4 are connected in parallel on the side wall of the main body of the blasting vessel.

[0032] A manual exhaust valve 5 is connected to the side wall of the blasting vessel body.

Since the rapid expulsion of gas will generate a lot of noise, the buffer cylinder 2 can also play a role in partially reducing noise. The gas is discharged through the cone-shaped gas diffuser 11 at the top. It not only achieves instantaneous release and improves the product quality of steam explosion equipment, but also greatly extends its service life. Moreover, it is convenient and inexpensive to maintain and replace in the later stages.
