Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of gasifiers, and in particular relates to a radiation waste boiler gasifier for producing superheated steam. Background Art
[0002] The high-temperature syngas generated by gasification can reach temperatures of 1300-1400°C. Typically, evaporation screens are deployed to absorb the heat from the high-temperature syngas, producing saturated steam as a byproduct. However, within a chemical plant, if back-end equipment requires higher-quality superheated steam, a radiant waste heat boiler that only produces saturated steam cannot meet the requirements of the chemical production area. Therefore, a separate waste heat boiler is required to produce high-temperature superheated steam as a byproduct. Furthermore, the layout of the heating surface for superheated steam generation has always been a challenge in the industry.
[0003] For example, a gasifier, in addition to the saturated steam generator, also required a steam superheater for superheated steam. This resulted in high overall cost and complex piping. For example, a convection waste boiler producing superheated steam employed a stacked, multi-layer spiral coil structure for its superheater. This design presented complexities, with small gaps between adjacent coils, which easily led to ash accumulation and overheating. Furthermore, the system presented numerous pipe threading and routing issues, making manufacturing difficult. Summary of the Invention
[0004] In order to solve the above problems existing in the prior art, the object of the present invention is to provide a radiation waste boiler gasification furnace that produces superheated steam.
[0005] The technical solution adopted in the present invention is:
[0006] A radiant waste boiler gasifier for producing superheated steam comprises a gasifier shell, wherein a gasification chamber, a radiation chamber, and a quenching chamber are sequentially arranged inside the gasifier shell from top to bottom. A burner is arranged at the upper portion of the gasifier chamber, a downcomer is arranged in the quenching chamber, a pulverized coal inlet is arranged on the burner, and a synthesis gas outlet is arranged on the quenching chamber shell. A radiant waste boiler water-cooled wall module and a superheating shield module are arranged in the radiation chamber, wherein the upper end of the radiant waste boiler water-cooled wall module is connected to the radiation chamber shell, and the upper end of the superheating shield module is fixed to the upper end of the radiant waste boiler water-cooled wall module. The superheating shield module is located in an annular space formed by the radiant waste boiler water-cooled wall module.
[0007] The pulverized coal is gasified and burned through the burner to generate synthesis gas, which passes through the gasification chamber and the radiation chamber in sequence, and is then discharged through the synthesis gas outlet on the shell of the quenching chamber; unsaturated water enters the water-cooled wall of the gasification chamber and the water-cooled wall module of the radiation waste boiler from the downcomer of the steam drum. After the unsaturated water absorbs heat upward, it becomes saturated water / water vapor and enters the steam drum through the riser; after the steam-water mixture is separated in the steam drum, the saturated steam enters the superheating screen module, and the saturated steam gradually absorbs heat and becomes superheated steam.
[0008] The water-cooled wall module of the radiation waste boiler and the water-cooled wall of the gasification chamber of the present invention can produce saturated steam. The generated saturated steam then enters the superheating screen module of the radiation chamber and gradually superheats the saturated steam into superheated steam by absorbing the heat of the high-temperature synthesis gas of 1300-1400°C, thus avoiding the complex design of arranging a steam superheater outside the gasification furnace.
[0009] The upper end of the radiation waste boiler water-cooled wall module of the present invention is connected to the shell of the radiation chamber, and the upper end of the superheated screen module is connected to the upper end of the radiation waste boiler water-cooled wall module, so that the radiation waste boiler water-cooled wall module and the superheated screen module are both suspended and expanded downward as a whole, avoiding the problems of multi-stage pipe threading and pipe giving.
[0010] As a preferred embodiment of the present invention, the radiation waste boiler water-cooled wall module includes a saturated water / steam outlet collection header fixed on the inner wall of the radiation chamber, the saturated water / steam outlet collection header is connected to the ceiling water-cooled wall, the lower end of the ceiling water-cooled wall is connected to the radiation waste boiler main body water-cooled wall, and the lower end of the radiation waste boiler main body water-cooled wall is connected to the saturated water / steam inlet collection header.
[0011] Unsaturated water enters the saturated water / steam inlet header from the downcomer, then passes through the main and ceiling water walls of the radiant waste boiler. After absorbing heat, the unsaturated water becomes saturated water / steam and is then discharged from the saturated water / steam outlet header, passing through the riser and entering the steam drum. The saturated water / steam outlet header supports the radiant waste boiler water wall module and superheater module.
[0012] As a preferred embodiment of the present invention, the lower end of the saturated water / steam inlet manifold is connected to a waste boiler expansion joint, which is mounted on the support steel plate between the radiation chamber and the quenching chamber. Because the radiation chamber's superheated shield module and the radiation boiler water-cooled wall module are both suspended, they expand downward; any expansion of the radiation boiler water-cooled wall is absorbed by the waste boiler expansion joint. One end of the expansion joint is connected to the saturated water / steam inlet manifold, and the other end is connected to the radiation chamber and quenching chamber support steel plates. This prevents wet syngas generated in the quenching chamber from entering the annular space of the radiation boiler.
[0013] As a preferred embodiment of the present invention, a reinforcement beam is fixed to the saturated water / steam outlet manifold, and the superheat shield module is connected to the underside of the reinforcement beam. The superheat shield module is suspended from the reinforcement beam, placing all weight on the reinforcement beam. The reinforcement beam, in turn, places weight on the saturated water / steam outlet manifold, and through the associated support structure, all weight is placed on the gasifier shell.
[0014] As a preferred embodiment of the present invention, the superheating screen module includes a saturated steam inlet collecting box and a superheated steam outlet collecting box, both of which are connected to the lower side of the reinforcing beam, and a number of superheating units are connected between the saturated steam inlet collecting box and the superheated steam outlet collecting box; the superheating unit includes an inlet collecting box and an outlet collecting box, a tube superheating screen is connected between the inlet collecting box and the outlet collecting box, an inlet connecting pipe is connected between the inlet collecting box and the saturated steam inlet collecting box, and an outlet connecting pipe is connected between the outlet collecting box and the superheated steam outlet collecting box, and both the inlet connecting pipe and the outlet connecting pipe pass through the ceiling water-cooled wall.
[0015] Saturated steam separated from the drum passes through the supersaturated steam inlet header, then descends through the ceiling water-cooled wall of the radiant waste boiler and enters the superheater inlet header. A tube-and-tube superheater is located below the inlet header. As the saturated steam descends, it absorbs heat from the high-temperature syngas. After descending, it reverses direction at the bottom of the tube-and-tube superheater before ascending. As the saturated steam gradually absorbs heat, it becomes superheated steam. This steam then ascends into the outlet header and is fed through the outlet connecting pipe to the superheated steam outlet header.
[0016] As a preferred embodiment of the present invention, an outlet expansion joint is connected between the outlet connecting pipe and the ceiling water-cooled wall. Considering the temperature difference between the superheated steam in the outlet connecting pipe and the saturated water / steam in the ceiling water-cooled wall, an outlet expansion joint is installed to absorb the expansion difference. Refractory material is applied to the outer walls of the inlet and outlet headers of the superheater to prevent the headers from overheating.
[0017] As a preferred embodiment of the present invention, the lower portion of the tube superheater is a U-shaped section or connected to an intermediate header. This U-shaped section can alleviate stress concentration issues when the lower portion of the tube superheater is reversed. Connecting the lower portion of the tube superheater to an intermediate header facilitates drainage.
[0018] As a preferred solution of the present invention, a drain port is connected to the bottom of the intermediate header.
[0019] As a preferred embodiment of the present invention, a plurality of tube superheating screens are evenly distributed along the circumferential direction with the axis of the water-cooled wall of the radiation waste boiler body as the center.
[0020] As a preferred embodiment of the present invention, the downcomer is a straight, open-top structure, and the quenching chamber is filled with water. This straight, open-top structure allows slag in the syngas to quickly enter the slag opening space at the bottom of the quenching chamber, preventing slag accumulation and blockage at the bottom of the radiant waste boiler water-cooled wall.
[0021] The beneficial effects of the present invention are:
[0022] 1. The water-cooled wall modules of the radiation waste boiler and the water-cooled walls of the gasification chamber of the present invention can produce saturated steam. The generated saturated steam then enters the superheating screen module of the radiation chamber. By absorbing the heat of the high-temperature synthesis gas at 1300-1400°C, the saturated steam is gradually superheated to superheated steam, avoiding the complex design of arranging a steam superheater outside the gasification furnace.
[0023] 2. The upper end of the radiation waste boiler water-cooled wall module of the present invention is connected to the inner wall of the radiation chamber, and the upper end of the superheating screen module is connected to the upper end of the radiation waste boiler water-cooled wall module. As a result, the radiation waste boiler water-cooled wall module and the superheating screen module are both suspended and expand downward as a whole, avoiding the problems of multi-stage pipe threading and pipe giving way.

DETAILED DESCRIPTION
[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.
[0028] like Figure 1As shown, the radiant waste boiler gasifier for producing superheated steam of this embodiment includes a gasifier shell 2. The gasifier shell 2 is provided with a gasification chamber 3, a radiation chamber 23 and a quenching chamber 24 in order from top to bottom. The upper portion of the gasification chamber 3 is provided with a burner 1, and the quenching chamber 24 is provided with a downcomer 19. The burner 1 is provided with a pulverized coal inlet, and the quenching chamber 24 is provided with a synthesis gas outlet 12. The radiation chamber 23 is provided with a radiant waste boiler water-cooled wall module and a superheating shield module. The upper end of the radiant waste boiler water-cooled wall module is connected to the inner wall of the shell of the radiation chamber 23, and the upper end of the superheating shield module is fixed to the upper end of the radiant waste boiler water-cooled wall module. The superheating shield module is located in the annular space formed by the radiant waste boiler water-cooled wall module.
[0029] The pulverized coal is gasified and burned through the burner 1 to generate synthesis gas, which passes through the gasification chamber 3 and the radiation chamber 23 in sequence, and is then discharged through the synthesis gas outlet 12 on the quenching chamber 24; unsaturated water enters the water-cooled wall of the gasification chamber 3 and the water-cooled wall module of the radiation waste boiler from the steam drum downcomer; after the unsaturated water absorbs heat upward, it becomes saturated water / water vapor and enters the steam drum through the riser; after the steam-water mixture is separated in the steam drum, the saturated steam enters the superheating screen module, and the saturated steam gradually absorbs heat and becomes superheated steam.
[0030] The water-cooled wall module of the radiation waste boiler and the water-cooled wall of the gasification chamber 3 of the present invention can produce saturated steam. The generated saturated steam then enters the superheating screen module of the radiation chamber 23, and gradually superheats the saturated steam into superheated steam by absorbing the heat of the high-temperature synthesis gas of 1300-1400°C, avoiding the complex design of arranging a steam superheater outside the gasification furnace.
[0031] The upper end of the radiation waste boiler water-cooled wall module of the present invention is connected to the inner wall of the shell of the radiation chamber 23, and the upper end of the superheated shield module is connected to the upper end of the radiation waste boiler water-cooled wall module, so that the radiation waste boiler water-cooled wall module and the superheated shield module are both suspended and expanded downward as a whole, avoiding the problems of multi-stage pipe threading and pipe letting.
[0032] Specifically, the radiation waste boiler water-cooled wall module includes a saturated water / steam outlet collection tank 18 fixed on the inner wall of the radiation chamber 23. The saturated water / steam outlet collection tank 18 is connected to the ceiling water-cooled wall 6. The lower end of the ceiling water-cooled wall 6 is connected to the radiation waste boiler main body water-cooled wall 9. The lower end of the radiation waste boiler main body water-cooled wall 9 is connected to the saturated water / steam inlet collection tank 13.
[0033] Unsaturated water enters the saturated water / steam inlet manifold 13 from the downcomer, then passes through the radiant waste boiler main water-cooled wall 9 and ceiling water-cooled wall 6. After absorbing heat, the unsaturated water ascends and becomes saturated water / water vapor. It is then discharged from the saturated water / steam outlet manifold 18 and enters the steam drum through the riser. This saturated water / steam outlet manifold 18 supports the radiant waste boiler water-cooled wall module and superheater module.
[0034] Furthermore, the lower end of the saturated water / steam inlet manifold 13 is connected to a waste boiler expansion joint 11, which is mounted on the supporting steel plate between the radiation chamber 23 and the quenching chamber 24. Because the superheating shield module and the radiation waste boiler water-cooled wall module of the radiation chamber 23 are both suspended, they expand downward; all downward expansion of the radiation waste boiler water-cooled wall is absorbed by the waste boiler expansion joint 11. One end of the expansion joint is connected to the saturated water / steam inlet manifold 13, and the other end is connected to the supporting steel plates of the radiation chamber 23 and the quenching chamber 24. This prevents wet syngas generated in the quenching chamber 24 from entering the annular space of the radiation waste boiler.
[0035] A reinforcing beam 4 is fixed to the saturated water / steam outlet manifold 18, and the superheating shield module is connected to the underside of the reinforcing beam 4. The superheating shield module is suspended from the reinforcing beam 4, placing all weight on the reinforcing beam 4. The reinforcing beam 4 then places weight on the saturated water / steam outlet manifold 18. Through the relevant supporting structure, all weight is placed on the gasifier shell 2.
[0036] Specifically, the superheating screen module includes a saturated steam inlet collecting box 16 and a superheated steam outlet collecting box 17, both of which are connected to the lower side of the reinforcing beam 4, and several superheating units are connected between the saturated steam inlet collecting box 16 and the superheated steam outlet collecting box 17; the superheating unit includes an inlet collecting box 8 and an outlet collecting box 7, and a tube superheating screen 10 is connected between the inlet collecting box 8 and the outlet collecting box 7, an inlet connecting pipe 20 is connected between the inlet collecting box 8 and the saturated steam inlet collecting box 16, and an outlet connecting pipe 21 is connected between the outlet collecting box 7 and the superheated steam outlet collecting box 17, and both the inlet connecting pipe 20 and the outlet connecting pipe 21 pass through the ceiling water-cooled wall 6.
[0037] The plurality of tube superheating screens 10 are evenly distributed along the circumference with the axis of the radiation waste boiler main body water-cooled wall 9 as the center. The number of tube superheating screens 10 and the number of parallel water channels per screen are determined according to the process requirements.
[0038] Saturated steam separated from the drum passes through the supersaturated steam inlet header 16, then descends through the ceiling water-cooled wall 6 of the radiant waste boiler water-cooled wall, entering the superheater inlet header 8. Below the inlet header 8, a tube-and-tube superheater 10 is located. As the saturated steam descends, it absorbs heat from the high-temperature syngas. After descending, it reverses direction at the bottom of the tube-and-tube superheater 10 and ascends. As the saturated steam gradually absorbs heat, it becomes superheated steam. This steam ascends into the outlet header 7 and is then fed through the outlet connecting pipe 21 to the superheated steam outlet header 17.
[0039] Furthermore, an outlet expansion joint 5 is connected between the outlet connecting pipe 21 and the ceiling water-cooled wall 6. Considering the temperature difference between the superheated steam in the outlet connecting pipe 21 and the saturated water / steam in the ceiling water-cooled wall 6, an outlet expansion joint 5 is provided to absorb the expansion difference. Refractory material is applied to the outer walls of the superheater's inlet and outlet headers 8 and 7 to prevent the headers from overheating.
[0040] In this embodiment, the lower portion of the tube-and-tube superheater 10 is formed into a U-shaped section 22 or connected to an intermediate header 15, the bottom of which is connected to a drain port 14. Reversing the flow of the tube-and-tube superheater 10 through the U-shaped section 22 alleviates stress concentration. Alternatively, a header solution can be employed, where the lower portion of the tube-and-tube superheater is connected to the intermediate header 15 to facilitate drainage.
[0041] The downcomer 19 is a straight open structure, and water is filled in the quenching chamber 24. The downcomer 19 is a straight open structure, and the slag in the synthesis gas can quickly enter the slag outlet space at the bottom of the quenching chamber 24, and the lower part of the radiation waste boiler water-cooled wall will not be blocked by slag accumulation.
[0042] The syngas path is as follows: Pulverized coal entering the gasifier is gasified and burned by burner 1 to generate syngas. The high-temperature syngas then flows down through gasification chamber 3 and into radiation chamber 23. After exchanging heat with the radiant waste boiler water-cooled wall module and superheater module, the syngas flows down into downcomer 19 and is discharged through syngas outlet 12 on the side wall of quench chamber 24.
[0043] The process of saturated steam generation is as follows: unsaturated water enters the water-cooled wall of vaporization chamber 3 and the water-cooled wall module of radiation waste boiler from the downcomer of the steam drum. After the unsaturated water absorbs heat upward, it becomes saturated water / water vapor and enters the steam drum through the riser.
[0044] The superheated steam generation process is as follows: Saturated steam separated from the drum passes through the supersaturated steam inlet manifold 16, then descends through the ceiling water-cooled wall 6 of the radiant waste boiler water-cooled wall, entering the superheater inlet manifold 8. The superheater heating surface is located below the inlet manifold 8. As the saturated steam descends, it absorbs heat from the high-temperature syngas. After descending, it passes through the intermediate manifold 15 or the U-shaped section 22 and ascends. A drain port 14 is provided on the intermediate manifold 15 to facilitate the removal of water accumulation caused by water pressure and any water accumulation that may occur during operation due to poor superheating. As the saturated steam gradually absorbs heat, it becomes superheated steam. The superheated steam ascends into the outlet manifold 7 and is fed through the outlet connecting pipe 21 to the superheated steam outlet manifold 17.
[0045] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
