Description

Technical Field

[0001] This utility model relates to the field of boiler equipment, specifically to a boiler ash and slag treatment device. Background Technology

[0002] Boiler ash refers to the final product formed after the minerals in coal undergo certain physicochemical changes under the high temperature caused by combustion in the furnace. Because ash can cause problems such as furnace fouling, slagging, corrosion, and wear on heating surfaces, affecting the normal operation of the boiler, it is essential to effectively and promptly remove the ash. A portion of the ash is discharged through the ash hopper behind the grate in a stoker-fired boiler, the cold ash hopper at the bottom of the furnace in a pulverized coal boiler, or the ash outlet and ash well at the bottom of a liquid ash discharge furnace; this process is called ash discharge.

[0003] The ash and slag discharged from the boiler are in a clump-like state. Direct discharge can easily cause blockage of the transmission device. In addition, the discharged ash and slag still contain some heat. Due to the lack of waste heat recovery devices, directly discarding the ash and slag will result in a waste of resources.

[0010] The heat storage mechanism includes a heat exchange rod connected to the heat collection platform, and a heat conduction platform is connected to one end of the heat exchange rod that passes through the ash and slag treatment platform. A protruding heat storage device is installed on the heat conduction platform.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figure 1-3 As shown, the present invention proposes a boiler ash and slag treatment device, which includes an ash and slag treatment platform 1, a crushing mechanism, a conveying mechanism, a heat collection mechanism, and a heat storage mechanism.

[0026] The crushing mechanism includes a feeder 21 installed on the top of the ash and slag processing platform 1. A crushing motor 22 is installed on the outside of the feeder 21. The output end of the crushing motor 22 is connected to a main roller 23 that penetrates the inner cavity of the feeder 21. A secondary roller 24 that cooperates with the main roller 23 is provided on one side of the main roller 23.

[0027] The transmission mechanism includes a transmission platform 31 set in the inner cavity of the ash and slag treatment platform 1, a transmission motor 33 installed on the outside of the transmission platform 31, a transmission shaft that passes through the transmission platform 31 installed at the output end of the transmission motor 33, and a rotatable transmission belt 34 sleeved on the outside of the transmission shaft.

[0028] The heat collection mechanism includes a suspension plate 41 disposed above the conveyor belt 34, a heat collection platform 42 formed on the lower part of the suspension plate 41, and a heat collection coil 43 formed on the end face of the heat collection platform 42 facing the conveyor belt 34.

[0029] The heat storage mechanism includes a heat exchange rod 51 connected to the heat collection platform 42. One end of the heat exchange rod 51 passes through the ash and slag treatment platform 1 and is connected to a heat conduction platform 52. A raised heat storage device 53 is installed on the heat conduction platform 52.

[0030] As an example of boiler ash and slag crushing and processing: Before the boiler ash and slag enter the ash and slag processing platform 1, the ash and slag are pre-processed by the crushing mechanism. The crushing motor 22 drives the main roller 23 to rotate. The main roller 23 and the auxiliary roller 24 are driven by gear meshing. The two are clamped to hold the ash and slag transmission gap, crushing the ash and slag into small particles. On the one hand, this can prevent large pieces from blocking the transmission channel, and on the other hand, it can facilitate the dissipation of waste heat.

[0031] In this embodiment, three sets of transmission platforms 31 are arranged in a stacked manner, and the transmission channels between the three sets of transmission platforms 31 are "S-shaped". When conveying ash particles, three sets of suspension plates 41 are arranged, each corresponding to a transmission platform 31. The heat collection coil 43 installed in the suspension plate 41 has a "serpentine" structure. The heat released by the ash particles heats the heat collection coil 43. After the heat is collected by the heat collection platform 42, the heat can be transferred to the heat storage device 53 for collection through the cooperation of the heat exchange rod 51 and the heat conduction platform 52. During the transmission process, the ash particles are cooled and the waste heat is collected, thereby improving the heat utilization efficiency.

[0032] As an example of the installation of the transmission station 31: The two sides of the transmission station 31 are symmetrically provided with a frame 32 that connects to the inner wall of the ash and slag treatment station 1, and an air gap is left between the frames 32.

[0033] To facilitate the discharge of ash particles, a discharge platform 6 is installed on one side of the conveyor platform 31, penetrating the outer wall of the ash processing platform 1, at the position of the lowest conveyor platform 31.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
