Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste heat boiler, and particularly relates to a waste heat boiler. BACKGROUND

[0002] The waste heat boiler is a device for producing steam by using the waste heat in high-temperature process gas in industrial production. For high-temperature process gas containing more ash medium, when the waste heat boiler is used to produce steam by using the high-temperature process gas, the ash medium in the high-temperature process gas will deposit in the waste heat boiler, causing the fouling thermal resistance to rise and affecting the heat exchange efficiency of the waste heat boiler. It is necessary to frequently shut down the waste heat boiler for ash removal operation, which affects the production efficiency, and the heat exchange efficiency of the waste heat boiler before and after ash removal is greatly different, causing the instability of the waste heat boiler process to increase. At the same time, the accumulated ash will cause the equipment to be easily damaged, which is not conducive to the long-period stable operation of the equipment. SUMMARY

[0003] The present application aims to provide a waste heat boiler to maintain the stability of the equipment itself and the heat exchange efficiency of the equipment.

[0004] To achieve the above-mentioned purpose, the present application provides a waste heat boiler, comprising:

[0005] An outer cylinder, a gas-liquid outlet and a water inlet are arranged on the cylinder wall of the outer cylinder;

[0006] An inner cylinder is arranged in the inner portion of the outer cylinder, and an evaporation cavity is formed between the outer cylinder and the inner cylinder, the gas-liquid outlet and the water inlet are communicated with the evaporation cavity, and an ash removal pipe is arranged at the bottom of the inner cylinder and communicated with the inner cylinder, and the ash removal pipe extends out of the outer cylinder;

[0007] A process gas inlet pipe is arranged on the cylinder wall of the outer cylinder, the process gas inlet pipe is communicated with the inner cylinder, and the process gas inlet pipe is used to introduce high-temperature process gas into the inner cylinder;

[0008] A process gas outlet pipe, the inlet end of the process gas outlet pipe extends into the inner cylinder, and the outlet end of the process gas outlet pipe extends out of the inner cylinder and the outer cylinder;

[0009] A turbulence component is arranged in the inner cylinder along the axis of the inner cylinder, and is used to guide the spiral flow of the high-temperature process gas in the inner cylinder.

[0010] With the above technical solution, high-temperature process gas enters the inner cylinder through the process gas inlet pipe and spirals downwards along the axis of the inner cylinder under the guidance of the turbulence-inducing components. During this process, some solid particles in the high-temperature process gas gradually lose kinetic energy and slide down the inner cylinder wall to the bottom. This process separates the gas and some solid particles in the high-temperature process gas. The separated solid particles are discharged to the outside of the waste heat boiler through the ash discharge pipe at the bottom of the inner cylinder, while the separated gas is discharged to the outside of the waste heat boiler through the process gas outlet pipe. At the same time, water entering the evaporation chamber between the inner and outer cylinders through the water inlet exchanges heat with the high-temperature process gas in the inner cylinder. The water in the evaporation chamber absorbs heat and evaporates, forming a gas-liquid mixture of saturated water and saturated steam. The gas-liquid mixture is discharged from the waste heat boiler through the gas-liquid outlet, ultimately yielding steam. It is evident that during the cooling and steam regeneration process of high-temperature process gas in this waste heat boiler, the gas, which contains a high amount of ash, can undergo natural separation of gas and some solid particles as it flows through the inner cylinder of the boiler. This allows the separated solid particles to be discharged from the waste heat boiler during normal operation, reducing ash accumulation on the heat exchange surfaces and thus minimizing the impact on the boiler's heat exchange efficiency. Furthermore, it reduces the frequency of ash removal operations, minimizing disruption to normal production and improving the boiler's overall efficiency. Simultaneously, the reduced ash accumulation enhances the reliability of the waste heat boiler's operation.

[0011] In some possible implementations, the aerodynamic component is a spiral aerodynamic plate, the outer ring of which is fixed to the inner wall of the inner cylinder.

[0012] In some possible implementations, the inner ring of the spiral baffle is connected to the outer wall of the process gas outlet pipe.

[0013] In some possible implementations, the process gas outlet pipe is coaxially arranged with the inner cylinder.

[0014] In some possible implementations, the lower part of the inner cylinder is a tapered section that narrows from top to bottom, and the ash discharge pipe is connected to the bottom outlet of the tapered section.

[0015] In some possible implementations, the inlet end of the process gas outlet pipe is positioned at a height close to the upper edge of the cone section.

[0016] In some possible implementations, the axis of the process gas inlet pipe is horizontally positioned, and there is a horizontal gap between the axis of the process gas inlet pipe and the axis of the inner cylinder.

[0017] In some possible implementations, the airflow of the process gas inlet pipe is guided along the tangential direction of the inner wall of the inner cylinder.

[0018] In some possible implementations, a gas-liquid separation box is also provided outside the outer cylinder. The gas-liquid separation box is provided with a steam outlet. The gas-liquid outlet is connected to the gas-liquid separation box through a gas-liquid conveying pipe. The gas-liquid separation box is used for gas-liquid separation, and the steam outlet is used to discharge the steam obtained from the gas-liquid separation.

[0019] In some possible implementations, the gas-liquid separator is further provided with a liquid outlet, which is connected to the water inlet via a liquid delivery pipe.

[0020] In some possible implementations, the inner wall of the inner cylinder is provided with a wear-resistant protective layer. Attached Figure Description

[0029] See Figure 1This invention provides a waste heat boiler, including an outer cylinder 4, an inner cylinder 6, a process gas inlet pipe 5, a process gas outlet pipe 3, and a turbulence-inducing component 7. The outer cylinder 4 and the inner cylinder 6 are vertically aligned, making it a vertical waste heat boiler. The outer cylinder 4 has a gas-liquid outlet 401 and a water inlet 403 on its wall. The inner cylinder 6 is located inside and fixed to the outer cylinder 4, forming an annular evaporation chamber 404 between them. Both the gas-liquid outlet 401 and the water inlet 403 are connected to the evaporation chamber 404. The water inlet 403 is used to introduce water to be evaporated into the evaporation chamber 404, and the gas-liquid outlet 401 is used to discharge the saturated water and saturated steam mixture obtained after evaporation from the evaporation chamber 404. A discharge pipe 602, connected to the bottom of the inner cylinder 6, is provided. The discharge pipe 602 extends out of the bottom of the outer cylinder 4 and can be connected to an external storage tank (not shown in the figure). A process gas inlet pipe 5 is provided on the wall of the outer cylinder 4. One end of the process gas inlet pipe 5 passes through the outer cylinder 4 and connects to the inner cylinder 6. The process gas inlet pipe 5 is used to introduce high-temperature process gas into the inner cylinder 6. The inlet end of the process gas outlet pipe 3 extends into the inner cylinder 6, and the outlet end of the process gas outlet pipe 3 extends out of the inner cylinder 6 and the outer cylinder 4. The process gas outlet pipe 3 is used to discharge the high-temperature process gas that has completed heat exchange in the inner cylinder 6 to the outside of the waste heat boiler. For example, the lower end of the process gas outlet pipe 3 is the inlet end, and the upper end is the outlet end. The high-temperature process gas after heat exchange enters the process gas outlet pipe 3 from the lower end and exits the process gas outlet pipe 3 from the upper end. The flow-disrupting component 7 is spirally arranged inside the inner cylinder 6 along the axis of the inner cylinder 6 to guide the high-temperature process gas to flow spirally inside the inner cylinder 6.

[0030] When the waste heat boiler is in operation, high-temperature process gas enters the inner cylinder 6 through the process gas inlet pipe 5. Under the guidance of the turbulence-inducing component 7, it spirals downwards along the axis of the inner cylinder 6. During this process, some solid particles in the high-temperature process gas gradually lose kinetic energy and slide down the cylinder wall of the inner cylinder 6 to the bottom. This process separates the gas and some solid particles in the high-temperature process gas. The separated solid particles are discharged from the outside of the waste heat boiler through the ash discharge pipe 602 at the bottom of the inner cylinder 6 and can be collected in a storage tank. The separated gas, after heat exchange, is discharged from the outside of the waste heat boiler through the process gas outlet pipe 3, either directly discharged or connected to other required processes. Meanwhile, water entering the evaporation chamber 404 between the inner cylinder 6 and the outer cylinder 4 through the inlet 403 exchanges heat with the high-temperature process gas in the inner cylinder 6 through the indirect wall. The water in the evaporation chamber 404 absorbs heat and evaporates, forming a steam-water mixture of saturated water and saturated steam. The steam-water mixture is discharged from the waste heat boiler through the gas-liquid outlet 401, and finally steam is obtained. The saturated steam produced is generally between 0.6-6 MPa, and steam at different pressures can also be produced according to actual needs.

[0031] It is evident that during the cooling and steam regeneration process of high-temperature process gas in this waste heat boiler, the gas, which contains a significant amount of ash, can undergo natural separation of gas and some solid particles as it flows through the inner cylinder 6 of the boiler. This allows the separated solid particles to be discharged from the waste heat boiler during normal operation, reducing ash accumulation on the heat exchange surfaces and thus minimizing the impact on the boiler's heat exchange efficiency. This ensures the stability of the boiler's heat exchange efficiency and reduces the frequency of ash removal operations, minimizing disruption to normal production and improving overall efficiency. Furthermore, the reduced ash accumulation enhances the reliability of the waste heat boiler's operation.

[0032] Exemplarily, the outer cylinder 4 can be a cylindrical structure, comprising, from top to bottom, an upper end cap, a straight section, and a lower end cap. A gas-liquid outlet 401 is located on the upper end cap of the outer cylinder 4, and a water inlet 403 is located on the lower end cap of the outer cylinder 4 or on the side wall of the straight section. In some examples, the water inlet 403 can be located on the lower side wall of the straight section. Exemplarily, the process gas inlet pipe 5 is located on the upper side wall of the straight section of the outer cylinder 4 and communicates with the upper interior of the inner cylinder 6.

[0033] In some embodiments, the turbulence-disrupting component 7 is a spiral turbulence-disrupting plate. The spiral turbulence-disrupting plate is spiral-shaped and has an inner ring and an outer ring. The outer ring diameter is larger than the inner ring diameter. The outer ring of the spiral turbulence-disrupting plate is fixed to the inner wall of the inner cylinder 6. The spiral turbulence-disrupting plate and the inner wall of the inner cylinder 6 enclose a spiral airflow channel. After the high-temperature process gas enters the inner cylinder 6 at high speed, it spirals downward in the spiral airflow channel. This causes some solid particles in the high-temperature process gas to gradually lose kinetic energy during the spiral descent and slide down along the inner wall of the inner cylinder 6 and the spiral turbulence-disrupting plate to the bottom of the inner cylinder 6. Exemplarily, the outer edge of the spiral turbulence-disrupting plate can be sealed to the inner wall of the inner cylinder 6, and there is no gap between the outer edge of the spiral turbulence-disrupting plate and the inner wall of the inner cylinder 6. The separated solid particles slide down along the inner wall of the inner cylinder 6 and the spiral turbulence-disrupting plate. Of course, there can also be a gap between the outer edge of the spiral baffle and the inner wall of the inner cylinder 6. It can be connected by discretely arranged connectors, so that the separated solid particles can slide vertically down along the inner wall of the inner cylinder 6, and the separation speed is faster.

[0034] In some embodiments, the inner ring of the spiral baffle is connected to the outer wall of the process gas outlet pipe 3. The spiral baffle is fixed to the process gas outlet pipe 3 by the inner ring, and there may be a seal between the edge of the inner ring of the spiral baffle and the outer wall of the process gas outlet pipe 3, or there may be a gap, and they are connected by discretely arranged connectors. At the same time, the outer ring of the spiral baffle may or may not be connected to the inner wall of the inner cylinder 6. As long as the spiral baffle can play a spiral guiding role for the high-temperature process gas, it is not limited to the connection forms listed in this embodiment.

[0035] Of course, in addition to continuous spiral baffles, the baffle component 7 can also be multiple short baffles arranged intermittently along the spiral direction. The multiple short baffles arranged along the spiral direction can also guide the high-temperature process gas in the spiral direction, thereby achieving the separation of solid particles in the high-temperature process gas.

[0036] In some embodiments, the process gas outlet pipe 3 is coaxially arranged with the inner cylinder. This arrangement makes the flow cross section of the turbulence component 7 the same in the circumferential direction, and the spiral flow velocity of the high-temperature process gas is more uniform and stable at various positions in the circumferential direction. It also makes it less likely that the separated solid particles will be deposited on the inner wall of the inner cylinder 6 or the turbulence component 7 due to differences in gas flow velocity.

[0037] Furthermore, such as Figure 1 As shown, in some embodiments, the lower part of the inner cylinder 6 is a tapered section 601 that narrows from top to bottom, and the ash discharge pipe 602 is connected to the bottom outlet of the tapered section 601. That is, the inner cylinder 6 is connected by an upper cylindrical section and a lower tapered section 601. The diameter of the cylindrical section and the upper diameter of the tapered section 601 can be the same or different. By setting the lower part of the inner cylinder 6 as a tapered section 601 that is larger at the top and smaller at the bottom, after the high-temperature process gas enters the inner cylinder 6, it spirals downward from top to bottom. When the high-temperature process gas flows to the tapered section 601, it spirals upward in the opposite direction under the action of the inner wall of the tapered section 601, so that the high-temperature process gas enters the process gas outlet pipe 3 located at the center of the inner cylinder 6. This makes the flow path of the separated gas more clearly separated from the flow path of the solid particles, reduces the re-mixing of the separated solid particles and gas, and is more conducive to the separation of solid particles.

[0038] In some examples, the taper of the conical section 601 is 5° to 30°, meaning the angle between the generatrix of the inner wall surface of the conical section 601 and the axis is 5° to 30°, specifically 5°, 8°, 10°, 15°, 19°, 23°, 27°, 30°, etc. Within this taper range, the reverse spiral ascent of the high-temperature process gas can be effectively achieved. If the taper is too small, the reverse spiral ascent effect is poor; if the taper is too large, the sliding effect of solid particles is poor, and they easily deposit on the inner wall of the conical section 601.

[0039] Furthermore, in this embodiment, the inlet end of the process gas outlet pipe 3 is positioned close to the height of the upper edge of the conical section 601. That is, the process gas outlet pipe 3 is coaxially arranged with the inner cylinder 6, and the lower end of the process gas outlet pipe 3 is the inlet end. The lower end of the process gas outlet pipe 3 is positioned slightly higher than the height of the upper edge of the conical section 601. This allows the high-temperature process gas, which is spiraling upwards in the opposite direction, to travel the shortest possible distance to enter the process gas outlet pipe 3 when it enters the conical section 601, thus reducing interference with the spiraling downward-moving high-temperature process gas.

[0040] For example, the inner cylinder 6 can also be a single cylindrical section. By reasonably setting the position and direction of the inlet and outlet ends of the process gas outlet pipe 3, such as setting the inlet end of the process gas outlet pipe 3 on the side wall of the inner cylinder 6 and extending the process gas outlet pipe 3 upwards at an angle to the waste heat boiler, the high-temperature process gas spirals downwards. The separated gas enters the process gas outlet pipe 3 through the inlet end located on the side wall of the inner cylinder 6 and is guided upwards for discharge. The separated solid particles continue to slide down the inner wall of the inner cylinder 6 due to their own gravity, thus achieving partial separation of solid particles. As long as the heat exchange process of the high-temperature process gas in the inner cylinder 6 can be reduced, the accumulation of ash on the heat exchange surface in the inner cylinder 6 can be reduced, thus minimizing the impact on the heat exchange efficiency of the waste heat boiler, and the structure is not limited to the form listed in this embodiment.

[0041] In some embodiments, the axis of the process gas inlet pipe 5 is horizontally arranged, and there is a horizontal gap between the axis of the process gas inlet pipe 5 and the axis of the inner cylinder 6. That is, the axis of the process gas inlet pipe 5 is horizontally arranged and offset from the axis of the inner cylinder 6. As a result, after the high-temperature process gas enters the inner cylinder 6, the airflow does not directly pass through the axis of the inner cylinder 6. Therefore, the airflow will not be perpendicular to the inner wall of the inner cylinder 6, the resistance it encounters is reduced, and the impact on the airflow velocity is smaller. This allows the high-temperature process gas to be guided more smoothly downwards in the spiral direction, achieving the separation effect of gas and solid particles in the high-temperature process gas.

[0042] Furthermore, in this embodiment, the airflow direction of the process gas inlet pipe 5 is tangential to the inner wall of the inner cylinder 6. That is, the flow direction of the high-temperature process gas entering the inner cylinder 6 is tangential to the inner wall of the inner cylinder 6, thereby further reducing the flow rate loss of the high-temperature process gas, causing the high-temperature process gas to spiral down at high speed, and improving the separation effect of the high-temperature process gas and solid particles.

[0043] In some possible implementations, such as Figure 1As shown, the waste heat boiler also includes a gas-liquid separation box 1 disposed outside the outer cylinder 4. The gas-liquid separation box 1 is provided with a steam outlet 101. The gas-liquid outlet 401 of the outer cylinder 4 is connected to the gas-liquid separation box 1 through a gas-liquid conveying pipe 2. The gas-liquid separation box 1 is used for gas-liquid separation, and the steam outlet 101 is used to discharge the steam obtained from the gas-liquid separation. Exemplarily, the gas-liquid separation box 1 is located above the outer cylinder 4. After evaporation in the steam chamber 404, a steam-water mixture of saturated water and saturated steam is formed. Therefore, the steam-water mixture enters the gas-liquid separation box 1 through the gas-liquid conveying pipe 2. The steam-water mixture completes the separation of saturated water and saturated steam in the gas-liquid separation box 1. The separated saturated water remains in the gas-liquid separation box 1, while the separated saturated steam is discharged from the steam outlet 101. The discharged saturated steam can be used in other processes or collected. It should be noted that the separation structure of saturated water and saturated steam is a mature technology and will not be described in detail here. For example, the gas-liquid separation box can be a steam drum, and a gas-liquid separation structure is provided inside the steam drum.

[0044] Furthermore, in this embodiment, the gas-liquid separator 1 is also provided with a liquid outlet 102, which is connected to the water inlet 403 on the outer cylinder 4 through a liquid conveying pipe 9.

[0045] In some possible implementations, the inner wall of the inner cylinder 6 is provided with a wear-resistant protective layer. Because the high-temperature process gas containing a large amount of ash enters the inner cylinder 6 at high speed and descends in a spiral direction, solid particles will wear down the inner wall of the inner cylinder 6. Therefore, providing a wear-resistant protective layer on the inner wall can improve the wear resistance of the inner cylinder 6 and prevent it from wearing through. For example, the wear-resistant protective layer can be made of wear-resistant alloy steel. Wear-resistant alloy steel is a mature technology and will not be described in detail here.

[0046] For example, the outer cylinder 4 can be divided into upper and lower sections, which are detachably assembled via flange 402, facilitating the insertion of the inner cylinder 6 into the outer cylinder 4. A skirt 8 is provided at the waist of the outer cylinder 4 to support and fix the entire waste heat boiler.

[0047] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
