Description

Technical Field

[0001] This utility model relates to the field of power plant dry ash silo technology, and in particular to a silicon carbide gasification device. Background Technology

[0002] In the dry ash storage and transportation system of thermal power plants, the silo is a key piece of equipment for storing fly ash. However, due to the fine particles and strong adsorption properties of fly ash, it easily absorbs moisture from the air during storage, causing caking and hardening. This results in the formation of solid "bridging" or "holes" in the cone-shaped area of ​​the silo. This caking problem not only hinders unloading but, in severe cases, can cause a sharp drop in the silo's emptying rate and even complete interruption of unloading, forcing the power plant to shut down for manual cleaning. This is not only costly and inefficient but also poses serious safety hazards. Therefore, a silicon carbide gasification device is proposed. Utility Model Content

[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides a silicon carbide gasification device, comprising: a gasification device, the gasification device including a tank, an air inlet pipe provided on the end face of the tank, and a gasification plate made of a perforated plate provided inside the tank.

[0004] Furthermore, the tank body is manufactured in one piece using a molding process.

[0005] Furthermore, the edge of the tank is provided with a flange connection surface.

[0006] Furthermore, the vaporization plate is made of silicon carbide.

[0007] Furthermore, the tank is designed with rectangular and trapezoidal structures.

[0008] Furthermore, the gasification devices are arranged in a circular array at the bottom of the silos, ash hoppers, flat-bottomed silos, and conical-bottomed silos.

[0009] Furthermore, the porosity of the gasification plate is 37.9%; the density of the gasification plate is 2.22 g / cm³. 3 Compressive strength of the vaporized plate: 67.7MPa; Flexural strength of the vaporized plate: 27.3MPa; Air permeability of the vaporized plate: 0.8m3 / m2·min; Temperature resistance of the vaporized plate: >400℃. Beneficial effects

[0010] Preheated gas is introduced through the air inlet pipe, enters the interior of the tank, and then enters the interior of the gasification plate. When in use, the preheated air is connected. This gasification device can fluidize powdery materials, increase the fluidity of the materials, make the material discharge smooth, and avoid bridging and arching.

[0011] The troughs are arranged in rectangular and trapezoidal structures. When they are evenly distributed in a circular pattern, trapezoidal gaps will be generated after several rectangular troughs are evenly distributed. These trapezoidal gaps are then evenly distributed through the trapezoidal troughs.

[0016] exist Figures 1 to 3 The correspondence between the component names or lines and the attached drawing numbers is as follows: gasification device 1, tank 11, gasification plate 12, air inlet pipe 13. Detailed Implementation

[0017] Please refer to Figures 1 to 3 ; This embodiment provides a silicon carbide gasification device, including: a gasification device 1, the gasification device 1 including a tank 11, an air inlet pipe 13 provided on the end face of the tank 11, and a gasification plate 12 made of a perforated plate provided inside the tank 11.

[0018] In practice, preheated gas is introduced from the air inlet pipe 13, enters the interior of the tank 11, and then enters the interior of the gasification plate 12. When in use, preheated air is supplied (this air is generally provided by a Roots blower or compressed air after pressure reduction). This gasification device 1 can fluidize powdery materials, increase the fluidity of the materials, make the material unloading smooth, and avoid bridging and arching.

[0019] Furthermore, the tank 11 is formed in one step using a molding process.

[0020] In practice, the tank is formed in one piece using a molding process, ensuring that the tank body and its joints are airtight and have an aesthetically pleasing appearance.

[0021] Before assembly, the material is shaped and adjusted to eliminate all welding deformation and internal stress, ensuring that the bottom surface and flange connection surface are smooth and straight. Under normal use, it can guarantee no malfunctions during a major overhaul. During the overhaul, only the perforated plate needs to be checked for damage, and it can be replaced in time.

[0022] Furthermore, the edge of the tank 11 is provided with a flange connection surface.

[0023] In practice, the flange connection face is used to connect adjacent tanks 11.

[0024] Furthermore, the vaporization plate 12 is made of silicon carbide.

[0025] In specific implementation, the perforated plate used in the gasification device 1 is a high-strength gasification plate 12 developed by our factory for the characteristics of dry ash silos in power plants. The main material of the gasification plate 12 is silicon carbide, which has the characteristics of wear resistance, pressure resistance and corrosion resistance. The fine and dense pores ensure a certain air permeability while preventing material backflow. It is a key component of the gasification device. The gasification area is generally designed according to 20%-25% of the bottom area of ​​the material storage silo, so as to avoid empty laying and missed laying, thereby enabling the material to achieve a good fluidization effect.

[0026] Furthermore, the tank 11 is rectangular (see reference). Figure 1 ) and trapezoid (reference) Figure 2 )Structure settings.

[0027] Figure 2 Two slots 11 are stacked together.

[0028] In practice, when the circumferential arrangement is uniformly distributed, trapezoidal gaps will be generated after the several rectangular grooves 11 are evenly distributed. At this time, the trapezoidal gaps are evenly distributed through the trapezoidal grooves 11.

[0029] Furthermore, the gasification devices 1 are arranged in a circular pattern at the bottom of the silos, ash hoppers, flat-bottomed silos, and conical-bottomed silos.

[0030] In specific implementation, refer to Figure 3 They are evenly distributed at the bottom of silos, ash hoppers, flat-bottomed silos, and conical-bottomed silos to prevent raw materials from caking inside these silos.

[0031] Furthermore, the porosity of the gasification plate 12 is 37.9%; the density of the gasification plate 12 is 2.22 g / cm³. 3 The compressive strength of the vaporized plate 12 is 67.7 MPa; the flexural strength of the vaporized plate 12 is 27.3 MPa; the air permeability of the vaporized plate 12 is 0.8 m3 / m2·min; and the temperature resistance of the vaporized plate 12 is >400℃.

[0032] In practical implementation, the temperature resistance of the vaporization plate 12 is >400℃, which allows the vaporization plate 12 to be used in high-temperature environments. The air permeability of the aeration plate 12 is 0.8 m3 / m2·min, which provides just the right air flow rate, ensuring effective fluidization while avoiding excessive energy consumption or excessive purging of materials. The compressive strength of the gasification plate 12 is 67.7 MPa; the flexural strength of the gasification plate 12 is 27.3 MPa; which is sufficient to withstand the huge material pressure in the silo and the long-term friction of the material, and the service life is significantly extended. The porosity of the aeration plate 12 is 37.9%; ensuring the fluidity of the airflow.
