[0015] The following is combined with Figure 1-5 This application is described in further detail.
[0016] This application discloses an oxygen supply device for a waste incinerator. (Refer to...) Figure 1 as well as Figure 2The waste incinerator oxygen supply device includes a distribution component 6, an oxygen sensor 3, and a control system 2. The oxygen sensor 3 is electrically connected to the control system 2, and the control system 2 is electrically connected to the distribution component 6. The oxygen sensor 3 includes a housing 31, a filter section 32, and a detection element 33. The housing 31 has a detection channel 311, and the filter section 32 and the detection element 33 are both located in the detection channel 311. The detection channel 311 has a detection port 312, which is exposed to the outside of the waste incinerator oxygen supply device. The filter section 32 is located between the detection port 312 and the detection element 33. The waste incinerator oxygen supply device includes a moving part 4, a cleaning part 41, and a drive component 5 for moving the moving part 4. The moving part 4 is slidably connected to the housing 31 along the direction from the detection element 33 to the filter section 32. The cleaning part 41 is connected to the moving part 4 and is used to pass through the filter holes of the filter section 32.
[0017] In use, the drive component 5 drives the moving part 4 to move up and down, so that the cleaning part 41 can penetrate into the filter hole of the filter part 32 to clean the filter part 32.
[0018] In some implementations, refer to Figure 1 as well as Figure 2 The oxygen sensor 3 is a zirconia sensor, and the detection element 33 includes a zirconia sensitive element. The filter part 32 is used to block impurities in the flue gas from entering the oxygen sensor 3, thereby reducing the impact of impurities in the flue gas on the detection.
[0019] In some embodiments, the oxygen sensor 3 is connected to the incinerator body, and the detection port 312 is located inside the incinerator body.
[0020] In some implementations, refer to Figure 3 as well as Figure 4 The drive assembly 5 includes an air blowing pipe 51 and a return spring 52. The air blowing pipe 51 is connected to the housing 31. The pipe inside the air blowing pipe 51 is connected to the detection channel 311. The air blowing pipe 51 is located on the side of the filter section 32 away from the detection port 312. The air blowing pipe 51 is used to blow fluid out of the detection channel 311. The waste incinerator oxygen supply device includes a baffle plate 53. The baffle plate 53 is connected to the moving part 4. The air blowing pipe is at least partially located on the side of the baffle plate 53 away from the filter section 32. One end of the return spring 52 is connected to the moving part 4, and the other end of the return spring 52 is connected to the housing 31.
[0021] In some embodiments, the air blowing pipe 51 is fixedly connected to the housing 31, and steam is blown out from the air blowing pipe 51.
[0022] When the filter section 32 needs to be cleaned, the air blowing pipe 51 can blow out steam. On the one hand, the air blowing cleans the filter section 32, blowing away impurities from the filter section 32. On the other hand, the blown steam drives the moving part 4 to move through the baffle plate 53, and the reset spring 52 drives the cleaning part 41 to reset, so that the cleaning part 41 cleans the filter section 32. The cleaning of the filter section 32 is achieved through two aspects, and the cleaning effect is better.
[0023] In some implementations, refer to Figure 3 as well as Figure 4 The baffle plate 53 has several through holes 531, which are disposed through the baffle plate 53. By providing through holes 531, the obstruction of the gas blown out of the air pipe 51 can be reduced, thereby improving the direct cleaning of the filter section 32 by steam.
[0024] In some implementations, refer to Figure 3 as well as Figure 4 The oxygen supply device for the waste incinerator includes a sliding rod 42, a fixed rod 43, and a fixed part 44. The fixed rod 43 is connected to the housing 31, and the fixed part 44 is connected to the fixed rod 43. The sliding rod 42 slides through the fixed part 44, and the moving part 4 is connected to the sliding rod 42. A return spring 52 is sleeved on the sliding rod 42. A baffle plate 53 is located between the fixed rod 43 and the detection port 312.
[0025] Specifically, refer to Figure 3 as well as Figure 4 There are four fixing rods 43, which are evenly distributed circumferentially along the axis of the detection through hole. The fixing rods 43 are fixedly connected to the housing 31, and the four fixing rods 43 are fixedly connected to each other. The fixing part 44 is located at the connection of the four fixing rods 43. The fixing part 44 and the four fixing rods 43 are an integral part. The length direction of the sliding rod 42 is parallel to the axis of the detection through hole. The sliding rod 42 is slidably connected to the fixing part 44 and passes through the fixing part 44.
[0026] In some implementations, refer to Figure 3 as well as Figure 4 The oxygen supply device for the waste incinerator includes a rotating assembly 45, which includes a contact part 451 and a fan blade 452. The contact part 451 is located on the side of the fixed rod 43 away from the detection port 312. A return spring 52 is located between the contact part 451 and the fixed part 44. One end of the return spring 52 is connected to the fixed part 44, and the other end of the return spring 52 is in contact with the contact part 451. The sliding rod 42 is cylindrical, and the fan blade 452 is connected to the sliding rod 42. Specifically, the fan blade 452 is located between the fixed rod 43 and the baffle plate 53. The sliding rod 42 can be rotated relative to the fixed part 44 in the circumferential direction along the length of the sliding rod 42, and the sliding rod 42 can also slide relative to the fixed part 44 in the length of the sliding rod 42.
[0027] In use, the air blowing pipe 51 blows air, which drives the sliding rod 42 to rotate through the fan blade 452, and drives the cleaning part 41 to move in the direction close to the filter part 32, increasing the cleaning range of the cleaning part 41 on the filter part 32. It is not limited by the setting of the cleaning part 41. If the cleaning range remains unchanged, the number of cleaning parts 41 can also be reduced accordingly. The structure is simple. The steam softens the impurities and blows them away, and the cleaning part 41 pushes out the unsoftened impurities for cleaning.
[0028] In some implementations, refer to Figure 3 as well as Figure 4 The air blowing pipe 51 includes a first sub-pipe 511 and a second sub-pipe 512. Both the first sub-pipe 511 and the second sub-pipe 512 are connected to the housing 31. The pipes of the first sub-pipe 511 and the second sub-pipe 512 are connected to the detection channel 311. The first sub-pipe 511 is located on the side of the fan blade 452 away from the detection port 312, and the second sub-pipe 512 is located between the baffle plate 53 and the detection port 312.
[0029] Specifically, refer to Figure 3 as well as Figure 4 The blowing pipe 51 includes a main pipe 513, one end of the first sub-pipe 511 and one end of the second sub-pipe 512 are connected to and communicate with the main pipe 513, the other end of the first sub-pipe 511 is connected to the incinerator body, the other end of the second sub-pipe 512 is connected to the incinerator body, and one end of the main pipe 513 is used to connect to the steam source.
[0030] In use, after the steam passes through the main pipe 513, part of the steam drives the fan blades 452 and the baffle plate 53 through the first sub-pipe 511 and cleans the filter section 32, while the other part directly cleans the filter section 32 through the second sub-pipe 512, thereby improving the cleaning effect of the steam on the filter section 32.
[0031] In some implementations, refer to Figure 1 as well as Figure 5The regulating component 6 includes a primary air duct 61 and a secondary air duct 62. The primary air duct 61 is used to communicate with the bottom of the incinerator body. One end of the secondary air duct 62 is connected to the primary air duct 61, and the other end of the secondary air duct 62 is used to connect and communicate with the top of the incinerator body. A secondary air fan 63 and a first blocking valve 64 are installed in the secondary air duct 62. The first blocking valve 64 is located between the secondary air fan 63 and the primary air duct 61. The waste incinerator oxygen supply device includes a flue gas duct 65 and a cold air duct 66. One end of the flue gas duct 65 is connected and communicates with the secondary air duct 62, and the cold air duct 66 is connected and communicates with the secondary air duct 62. Both the flue gas duct 65 and the cold air duct 66 are located between the secondary air fan 63 and the first blocking valve 64. The control system 2 is electrically connected to the first blocking valve 64, and the control system 2 is used to control the opening and closing of the first blocking valve 64.
[0032] In some implementations, refer to Figure 1 as well as Figure 5 The waste incinerator oxygen supply device includes a second blocking valve 661, which is located inside the cold air duct 66 and connected to the inner wall of the cold air duct 66; the waste incinerator oxygen supply device includes a third blocking valve 651, which is located inside the flue gas inlet duct 65 and connected to the inner wall of the flue gas inlet duct 65; the control system 2 is electrically connected to the second blocking valve 661 and the third blocking valve 651, and the control system 2 is used to control the opening and closing of the second blocking valve 661 and the third blocking valve 651.
[0033] When the oxygen sensor 3 detects that the oxygen level in the incinerator exceeds a predetermined value, the control system 2 controls the third blocking valve 651 to open, and the secondary fan 63 drives the flue gas in the flue gas inlet channel 65 into the incinerator, thereby reducing the oxygen content in the incinerator. When the oxygen sensor 3 detects that the oxygen level in the incinerator is lower than a predetermined value, the control system 2 controls the second blocking valve 661 to open, and the secondary fan 63 drives the cold air in the cold air channel 66 into the incinerator, thereby increasing the oxygen content in the incinerator.
[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
