Abstract
Description
Technical Field
[0001] This application relates to the field of flues, and more particularly to a vaporization flue. Background Technology
[0002] The converter gasification flue, also known as a waste heat boiler, is one of the main supporting equipment for converter steelmaking. When working, this equipment must collect high-temperature flue gas to the maximum extent and withstand the highest furnace gas temperature and drastic and frequent temperature changes.
[0003] The flue gas flows through the vaporization flue under the negative pressure generated by the circulating pump, and then enters the corresponding flue gas treatment equipment. Depending on the different flue gas treatment requirements, the subsequent treatment equipment of the vaporization flue is also different.
[0004] Therefore, when other flue gas treatment equipment is needed, the original equipment needs to be removed and then connected to the corresponding treatment equipment. This method is cumbersome and reduces the efficiency of flue gas treatment. Utility Model Content
[0005] To facilitate the replacement of flue gas treatment equipment and improve flue gas treatment efficiency, this application provides a vaporization flue.
[0006] The vaporization flue provided in this application adopts the following technical solution:
[0007] A vaporization flue includes a first flue, a connecting flue at one end of the first flue, a second flue connected to one side of the connecting flue, and a third flue connected to the other side of the connecting flue. The second and third flues are arranged opposite to each other, and a guide is provided inside the connecting flue.
[0008] By adopting the above technical solution, high-temperature flue gas enters from the first flue and then enters the second or third flue under the action of the guide component in the connecting flue. The second and third flues are respectively connected to different flue gas treatment equipment, thereby enabling the flue gas treatment equipment to be adjusted and replaced at any time, thus improving the flue gas treatment efficiency.
[0009] Optionally, the guide includes a guide plate rotatably connected inside the connecting flue, and a drive motor is provided on the outside of the connecting flue to drive the guide plate to rotate. When the guide plate blocks the second flue, the first flue is connected to the third flue, and when the guide plate blocks the third flue, the first flue is connected to the second flue.
[0010] By adopting the above technical solution, the drive motor drives the guide plate to rotate, so that the guide plate can block the second or third flue, thereby quickly changing the flue gas direction and thus quickly replacing the flue gas treatment equipment.
[0011] Optionally, the first flue is provided with a cooling assembly, which includes a cooling grille disposed on the inner wall of the first flue. The cooling grille is provided with a cooling channel, one end of which extends out from the lower end of the cooling grille and the other end of which extends out from the upper end of the cooling grille.
[0012] By adopting the above technical solution, the flue gas flows in the first flue and passes through the cooling grid and through the channels of the cooling grid. The cooling medium flows in the cooling channel inside the cooling grid and exchanges heat with the flue gas in the first flue. By increasing the contact area with the flue gas, the efficiency of heat exchange is further improved and the utilization rate of the high-temperature waste heat of the flue gas is increased.
[0013] Optionally, a spray assembly is provided above the cooling grille. The spray assembly includes a plurality of spray pipes evenly arranged around the first flue. One end of each spray pipe is located outside the first flue, and the other end is located inside the first flue and is equipped with a spray head.
[0014] By adopting the above technical solution, when there is no flue gas in the first flue, the spray assembly sprays cleaning liquid onto the cooling grid. The cleaning liquid enters the first flue through the spray pipe and is sprayed through the spray head to clean the cooling grid.
[0015] Optionally, a rotating assembly is provided between the spray head and the spray pipe. The rotating assembly includes a sleeve rotatably connected to the spray pipe. The inner wall of the sleeve is provided with helical blades. A connecting pipe is provided at the end of the sleeve away from the spray pipe. The connecting pipe is inclined relative to the sleeve, and the spray head is installed on the connecting pipe.
[0016] By adopting the above technical solution, the cleaning liquid is sprayed onto the cooling grid along the spray pipe, sleeve and connecting pipe and through the spray head. At the same time, the cleaning liquid impacts the spiral blades, which causes the sleeve to rotate. The sleeve drives the connecting pipe to rotate, and the connecting pipe drives the spray head to rotate within a certain range, thereby increasing the spray range of the spray head and improving the cleaning effect of the cleaning liquid.
[0017] Optionally, the sleeve is further provided with a protective element for protecting the spray head. The protective element includes a plurality of protective blades that are hinged around the sleeve. All the protective blades are closed to form a protective cover, and the spray head is located inside the protective cover. When the sleeve is rotated, the protective blades separate from each other.
[0018] By adopting the above technical solution, when the sleeve rotates, the protective blades separate under the action of centrifugal force, so that the spray head can spray cleaning liquid onto the cooling grid. When the spray head is not spraying cleaning liquid, the sleeve does not rotate, and the protective blades close under the action of gravity, thereby preventing the flue gas from contacting the spray head.
[0019] Optionally, the cross-sections at both ends of the guide plate are set as inclined surfaces, and the inclined surfaces are inclined toward the side wall of the connecting flue.
[0020] By adopting the above technical solution, the inclined surface on the guide plate scrapes the inner wall of the connecting flue during the movement, thereby cleaning the connecting flue.
[0021] Optionally, a limiting block is abutted below the cooling grille, and the limiting block is fixed to the inner wall of the first flue.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] High-temperature flue gas enters from the first flue and then enters the second or third flue under the action of the guide component in the connecting flue. The second and third flues are respectively connected to different flue gas treatment equipment, which allows the flue gas treatment equipment to be adjusted and replaced at any time to improve flue gas treatment efficiency.
[0024] Cooling medium flows in the cooling channel inside the cooling grille. The cooling medium exchanges heat with the flue gas in the first flue. By increasing the contact area with the flue gas, the efficiency of heat exchange is further improved, and the utilization rate of the high-temperature waste heat of the flue gas is increased.
[0025] When there is no flue gas in the first flue, the spray assembly sprays cleaning fluid onto the cooling grille. The cleaning fluid enters the first flue through the spray pipe and is sprayed through the spray head to clean the cooling grille. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses a vaporization flue. (Refer to...) Figure 1A vaporization flue includes a vertically arranged first flue 1, a connecting flue 2 installed at the upper end of the first flue 1, a second flue 3 and a third flue 4 respectively connected to both sides of the connecting flue 2, the second flue 3 and the third flue 4 being arranged opposite to each other, and a guide 5 is provided inside the connecting flue 2 to guide the flue gas flow to the second flue 3 or the third flue 4.
[0032] The guide member 5 includes a guide plate 51 rotatably connected inside the connecting flue 2. The guide plate 51 abuts against the inner wall of the connecting flue 2. A drive motor 52 is installed on the outside of the connecting flue 2. The output shaft of the drive motor 52 passes through the connecting flue 2 and is fixedly connected to the guide plate 51. The drive motor 52 drives the guide plate 51 to rotate. When the guide plate 51 blocks the second flue 3, the first flue 1 is connected to the third flue 4. When the guide plate 51 blocks the third flue 4, the first flue 1 is connected to the second flue 3.
[0033] Both ends of the guide plate 51 are designed as inclined surfaces, which slope towards the side wall of the connecting flue 2. During movement, the inclined surfaces on the guide plate 51 scrape the inner wall of the connecting flue 2, thereby cleaning the connecting flue 2.
[0034] The drive motor 52 drives the guide plate 51 to rotate, so that the guide plate 51 can block the second flue 3 or the third flue 4. The high-temperature flue gas enters from the first flue 1, and then enters the third flue 4 or the second flue 3 under the action of the guide plate 51 in the connecting flue 2. The second flue 3 and the third flue 4 are respectively connected to different flue gas treatment equipment, so that the flue gas treatment equipment can be adjusted and replaced at any time.
[0035] A cooling assembly 6 is provided inside the first flue 1. The cooling assembly 6 includes a cooling grille 61 installed on the inner wall of the first flue 1. A limiting block abuts below the cooling grille 61 and the limiting block is fixed to the inner wall of the first flue 1. A cooling channel 62 is provided inside the cooling grille 61. One end of the cooling channel 62 extends out from the lower end of the cooling grille 61 and the other end extends out from the upper end of the cooling grille 61.
[0036] The flue gas flows in the first flue 1 and passes through the cooling grid 61 and through the holes of the cooling grid 61. The cooling medium enters the cooling channel 62 from the lower end of the cooling grid 61 and then flows out from the upper end of the cooling grid 61. In this process, by increasing the contact area with the flue gas, the cooling medium exchanges heat with the flue gas in the first flue 1, thereby efficiently utilizing the high-temperature waste heat of the flue gas.
[0037] A spray assembly 7 is provided above the cooling grille 61. The spray assembly 7 includes an annular pipe surrounding the outside of the first flue 1. Multiple spray pipes 71 are evenly arranged around the first flue 1 on the annular pipe. One end of the spray pipe 71 is connected to the annular pipe, and the other end is inserted into the inside of the first flue 1 and is equipped with a spray head 72.
[0038] When there is no flue gas in the first flue 1, the spray assembly 7 sprays cleaning liquid onto the cooling grille 61. The cleaning liquid enters the first flue 1 through the spray pipe 71 and is sprayed through the spray head 72 to clean the cooling grille 61.
[0039] To improve the cleaning effect of the cooling grille 61, a rotating assembly 8 is provided between the spray head 72 and the spray pipe 71. The rotating assembly 8 includes a sleeve 81 rotatably connected to the spray pipe 71. A spiral blade 82 is installed on the inner wall of the sleeve 81. A connecting pipe 83 is installed at the end of the sleeve 81 away from the spray pipe 71. The connecting pipe 83 is inclined relative to the sleeve 81, and the spray head 72 is installed on the connecting pipe 83.
[0040] The cleaning fluid flows sequentially through the spray pipe 71, the sleeve 81 and the connecting pipe 83, and is sprayed onto the cooling grid 61 through the spray head 72. At the same time, the cleaning fluid impacts the spiral blades 82, which in turn causes the sleeve 81 to rotate. The sleeve 81 drives the connecting pipe 83 to rotate, and the connecting pipe 83 drives the spray head 72 to rotate within a certain range, thereby increasing the spray range of the spray head 72.
[0041] The sleeve 81 is also provided with a protective element for protecting the spray head 72. The protective element includes multiple protective blades 9 that are hinged around the sleeve 81. All the protective blades 9 are closed to form a protective cover, and the spray head 72 is located inside the protective cover. When the sleeve 81 is rotated, the protective blades 9 are separated from each other.
[0042] When the sleeve 81 rotates, the protective blades 9 separate under the action of centrifugal force, so that the spray head 72 can spray cleaning liquid onto the cooling grid 61. When the spray head 72 is not spraying cleaning liquid, the sleeve 81 does not rotate. At this time, the protective blades 9 close under the action of gravity, thereby blocking the flue gas from contacting the spray head 72.
[0043] The implementation principle of a vaporization flue in this application embodiment is as follows: the flue gas passes through the first flue 1 and flows to the second flue 3 or the third flue 4 under the guidance of the guide plate 51. During this process, the cooling medium flows in the cooling channel 62 and exchanges heat with the flue gas through the cooling grid 61. After the flue gas treatment is completed, the spray assembly 7 sprays cleaning liquid onto the cooling grid 61.
[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
