Description

[Technical field]

[0001] The present invention relates to a waste resource recovery facility, and more particularly to a loading vessel for a waste volume expansion and stabilization process. [Background technology]

[0002] Industrial waste such as slag, furnace tailings, furnace stones, fly ash, leaching residues, refractory lining materials, mining ores, tailing materials, etc. cannot be turned into resources unless they are stabilized before recycling to remove unstable components. Stabilized industrial waste can be used as an additive for concrete.

[0003] As shown in FIG. 5, the conventional slag stabilization process mainly involves placing slag 95 in a frame 90 with a bottom plate 91 having a number of meshes 912, providing a steam system 93 below the plate 91, and covering the frame 90 with a cover 92 from above. The steam generated by the steam system 93 is sent through the meshes 912 of the plate 91 into the frame 90, and the steam reacts with the slag 95 in the frame 90 to remove the unstable components in the slag 95. This method can turn, for example, calcium oxide, magnesium oxide, and other expansive substances into stable calcium hydroxide, magnesium hydroxide, and other stable products.

[0004] However, in the conventional slag stabilization process, steam diffuses from the bottom to the top of the loading plate 91, but the steam is blocked by the accumulated slag 95 and cannot diffuse to the slag 95 located relatively higher. As a result, the slag 95 at the top cannot be mixed sufficiently with the steam, resulting in a low stabilization effect for the slag 95 and leaving room for improvement. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above-mentioned shortcomings, the main object of the present invention is to provide a loading vessel for a waste volume expansion stabilization process in which high-pressure steam is uniformly mixed with the waste in the loading vessel to perform waste stabilization treatment. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a loading vessel for a waste volume expansion and stabilization process for containing waste, the loading vessel for the waste volume expansion and stabilization process comprising: A storage tank; a steam introduction device provided in the storage tank and connecting an external space of the storage tank to the storage tank; The steam introduction device comprises a plurality of steam pipes spaced apart within the storage tank, each of the steam pipes having a first end and a second end, each of the first end and second end having an opening, the opening at the first end of each of the steam pipes connecting the steam pipe to the external space of the storage tank, and the opening at the second end of each of the steam pipes connecting the steam pipe to the storage tank.

[0007] By utilizing the above technical features, industrial waste such as slag, furnace tailings, furnace stones, fly ash, leaching residues, refractory lining materials, mining ores, tailing materials, etc. are placed in the storage tank of the loading vessel, and the loading vessel is then placed in a steam pressure cooker. High-pressure steam is introduced into the steam pressure cooker, and the high-pressure steam is sent from the opening of the first end of the steam pipe, and further flows into the tank from the opening of the second end of the steam pipe to thoroughly mix with the waste. The high-pressure steam is introduced into the inside of the waste, and the steam and the waste are uniformly mixed, thereby improving the effect of the waste stabilization process and shortening the time required to complete it.

[0009] As shown in Figures 1 to 4, the waste volume expansion and stabilization process equipment of the present invention includes a steam pressure vessel 10 and a loading vessel 20, 20A disposed in the steam pressure vessel 10 for receiving waste materials 50, such as slag, furnace tailings, furnace stones, fly ash, leaching residues, refractory lining materials, mining ores, tailing materials, etc.

[0010] As shown in FIG. 1, the steam pressure cooker 10 comprises a horizontally placed cylindrical body 11 and a lid 13. The body 11 is connected to an external steam facility by a connecting pipe 15, and high-pressure steam is introduced into the body 11 through the connecting pipe 15. The body 11 can be opened at one end or at both ends. The number of lids 13 corresponds to the number of openings of the body 11, and the openings of the body 11 can be opened or closed.

[0011] As shown in Figures 1 and 2, the first preferred embodiment of the loading container 20 comprises a storage tank 22 and a steam introduction device 30, and the top of the storage tank 22 is open so that waste 50 can be poured into the storage tank 22 through the top opening of the storage tank 22, and a number of wheels 215 can be selectively attached to the bottom of the loading container 20 so that the loading container 20 can be pushed.

[0012] The steam introduction device 30 is provided in the storage tank 22 of the loading vessel 20, thereby communicating the outside space of the storage tank 22 with the storage tank 22, i.e., communicating the steam pressure cooker 10 with the storage tank 22. The steam introduction device 30 includes a plurality of steam pipes 31 arranged at intervals in an upright state in the storage tank 22, each of which may be made of a metal pipe, has a first end and a second end, and is connected to the front end of the storage tank 22. The first end is located above the second end, and the first end and the second end each have an opening, the opening of the first end of each steam pipe 31 connects the steam pipe 31 to the external space, the opening of the second end of each steam pipe 31 connects the steam pipe 31 to the storage tank 22, and a gap is formed between the second end of each steam pipe 31 and the inner wall surface of the storage tank 22 so that the opening of the second end of each steam pipe 31 is not sealed by the inner wall surface of the storage tank 22.

[0013] Furthermore, it is preferable that a plurality of meshes are provided around the outer periphery of each steam pipe 31, the meshes being spaced apart and connecting the steam pipe 31 to the storage tank 22, thereby increasing the number of holes through which the high-pressure steam flows out of each steam pipe 31, increasing the contact area between the high-pressure steam and the waste 50, and uniformly mixing the high-pressure steam and the waste 50.

[0014] A plurality of support frames are arranged at intervals adjacent to the upper surface inside the storage tank 22 of the loading vessel 20, and the steam introduction device 30 has at least one support member 33 that abuts against the plurality of support frames, and a plurality of steam pipes 31 are fixed to the at least one support member 33 so as to be arranged at intervals, thereby providing the steam pipes 31 in an upright position within the storage tank 22, and the at least one support member 33 has a plurality of through holes arranged at intervals, through which the steam pipes 31 are inserted, and the steam pipes 31 are fixed to the at least one support member 33 by welding.

[0015] The length of the steam pipe 31 can be set to correspond to the shape of the storage tank 22, and the opening at the bottom end of the steam pipe 31 has a gap between the second end of the steam pipe 31 and the inner bottom surface or inner surface of the storage tank 22 so that it is not sealed by the inner bottom surface or inner surface of the storage tank 22.

[0016] 1 and 3, in the second preferred embodiment, the steam introduction device 30A includes a plurality of steam pipes 31, 31A arranged upright and spaced apart, and the length of one of the steam pipes 31A is shorter than the length of the other steam pipes 31. Therefore, the second ends of the two steam pipes 31, 31A extend at different depths relative to the waste 50 in the storage tank 22, and the different lengths of the steam pipes 31, 31A allow high-pressure steam to be delivered to the waste 50 from different heights, so that the high-pressure steam and the waste 50 can be mixed uniformly.

[0017] As shown in FIG. 1 and FIG. 4, the third preferred embodiment of the loading vessel 20A includes a storage tank 22A and a steam introduction device 30B. The steam introduction device 30B includes a plurality of steam pipes 31B arranged horizontally at intervals in the storage tank 22A. A first end of each of the steam pipes 31B penetrates a side wall of the storage tank 22A, so that an opening of the first end of each of the steam pipes 31B communicates with the external space of the storage tank 22A, i.e., the steam pressure cooker 10. A space is formed between the second end of each of the steam pipes 31B and the inner wall surface of the storage tank 22A, and the opening of the second end of each of the steam pipes 31B communicates with the storage tank 22A.

[0018] As shown in Figures 1 to 4, after the waste 50 is put into the storage tank 22, 22A, the loading vessel 20, 20A is put into the steam pressure cooker 10, and high pressure steam is introduced into the steam pressure cooker 10. The high pressure steam flows into the steam pipes 31, 31A, 31B from the first end openings of the steam pipes 31, 31A, 31B, and further flows into the storage tanks 22, 22A from the second end openings of the steam pipes 31, 31A, 31B, and is thoroughly and uniformly mixed with the waste 50 in the storage tanks 22, 22A, thereby carrying out the waste stabilization process.

[0019] In use, as shown in Fig. 1, multiple loading vessels 20, 20A are placed in one steam pressure cooker 10, and waste 50 placed in the multiple loading vessels 20, 20A are simultaneously subjected to a waste stabilization process. The loading vessels 20, 20A for waste volume expansion stabilization process of the present invention send high-pressure steam in the steam pressure cooker 10 into the steam pipes 31, 31A, 31B via the openings at the first ends of the steam pipes 31, 31A, 31B, and further into the storage tanks 22, 22A from the openings at the second ends of the steam pipes 31, 31A, 31B to thoroughly mix with the waste 50, and increase the contact area between the steam and the waste 50 to uniformly mix the steam and the waste 50. This method can improve the effect of the waste stabilization process while shortening the time to complete it. [Explanation of symbols]
