[0006] Therefore, the utility model aims to provide a labyrinth-type non-wet electricity special effect desulfurization and dust removal device, the purpose of which is to desulfurize and remove dust from flue gas without wet electricity.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a labyrinth-type non-wet electric special effect desulfurization and dust removal device, comprising a processing chamber, a dust collecting hopper is welded at the bottom of the processing chamber, a dust removal component is installed at the lower side of the processing chamber, and an activated carbon filter filler is installed inside the processing chamber and at the top of the dust removal component;

[0008] The dust removal assembly includes an annular plate A, a group of ring plates are installed at equal intervals on the top of the annular plate A, and the sizes of the group of ring plates are from large to small from the outside to the inside. An annular plate B is welded between the top ends of a group of ring plates, and a filter screen is fixed at the center of the top end of the annular plate B. A labyrinth air duct is formed between the annular plate A, the annular plate B and the group of ring plates, and an exhaust outlet connected to the labyrinth air duct is opened through the inner side of the bottom of the annular plate A.

[0009] As a preferred solution of the labyrinth-type non-wet electric special effect desulfurization and dust removal device described in the utility model, a partition is welded between the opposite surfaces of the two connected ring plates, an air duct is formed between the two connected ring plates and the partition, a connecting pipe A for connecting the air inlet and air outlet ends of the two connected air ducts is welded on the top of the annular plate B, and connecting air holes are opened through the top of the annular plate B and at the air inlet and outlet of the connecting pipe A.

[0010] As a preferred solution of the labyrinth-type non-humidity electric special effect desulfurization and dust removal device described in the utility model, wherein: both sides of the inside of the air duct are welded with staggered impact blocks.

[0011] As a preferred solution of the labyrinth-type non-humidity electric special effect desulfurization and dust removal device described in the utility model, a speed change tube is welded at the air inlet of the outermost ring plate, and an air inlet bin is welded at the air inlet end of the speed change tube.

[0012] As a preferred solution of the labyrinth-type wet-free electric special effect desulfurization and dust removal device described in the utility model, a power source is welded inside the innermost ring plate, and a scraping strip for cleaning the bottom end surface of the filter is installed on the top of the power source driving end, and a connecting pipe B is welded between the air outlet of the labyrinth-type air duct and the air inlet of the power source.

[0013] As a preferred solution of the labyrinth-type non-wet electric special effect desulfurization and dust removal device described in the utility model, the power source includes four welding bars welded on the ring plate, a shell is welded between the opposite ends of the four welding bars, a driving shaft is rotatably installed on the bottom of the inner wall of the shell through a bearing, and the top end of the driving shaft is located above the shell and connected to the bottom end of the scraper strip.

[0015] Beneficial effects of the utility model:

[0016] 1. In the utility model, the diameter of the air inlet chamber is much larger than the diameter of the speed change pipe.

The labyrinth-type air duct prolongs the residence time of the smoke in a limited space, so that the smoke hits the impact block more times, which is more conducive to the mutual aggregation of dust particles.

[0018] 3. In the utility model, after the smoke enters the interior of the shell, the driving shaft is forced to rotate, thereby driving the scraper bar to rotate, so as to clean the dust at the filtering part of the bottom section of the filter, and avoid the dust from clogging the filter mesh holes of the filter, thereby ensuring the filtering efficiency of the filter during long-term operation. The kinetic energy of the smoke is used to drive the scraper bar to rotate, thereby realizing self-cleaning of the filter, without the need for manual cleaning, saving time and effort, and without the need for electricity to reduce the cost of use.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a labyrinth-type non-humidity electric special effect desulfurization and dust removal device, which includes a processing bin 1, a dust collecting hopper 2 is welded at the bottom of the processing bin 1, and the processing bin 1 is connected to the inside of the dust collecting hopper 2, and the outer edge of the bottom of the dust collecting hopper 2 is welded with a leg, and a dust removal component 5 is installed on the lower side of the processing bin 1, and an activated carbon filter filler 6 is installed inside the processing bin 1 and at the top of the dust removal component 5. After the flue gas passes through the inside of the shell 582, it is discharged to the outside through the air outlet 583, and the dust is filtered and dusted through the filter screen 54. Then, the flue gas passes through the inside of the activated carbon filter filler 6 for desulfurization treatment, and is finally discharged through the outlet at the top of the processing bin 1;

[0031] The dust removal assembly 5 includes an annular plate A51, a group of ring plates 52 are installed at equal intervals on the top of the annular plate A51, and the sizes of the group of ring plates 52 are from large to small from the outside to the inside. Some of the outermost ring plates 52 are penetrated with air inlets, and an annular plate B53 is welded between the tops of a group of ring plates 52. A filter screen 54 is fixed at the center of the top of the annular plate B53. A labyrinth air duct is formed between the annular plate A51, the annular plate B53 and the group of ring plates 52. The labyrinth air duct prolongs the residence time of the smoke in a limited space, makes the smoke collide with the impact block 511 more times, and is more conducive to the mutual aggregation of dust particles. An exhaust port 56 connected to the labyrinth air duct is penetrated inwardly from the bottom of the annular plate A51, and the exhaust port 56 is connected to the inside of the innermost air duct 512.

[0032] A partition plate 510 is welded between the opposite surfaces of the two connected ring plates 52, and the top and bottom of the partition plate 510 are respectively welded to the opposite surfaces of the annular plate B53 and the annular plate A51, and an air duct 512 is formed between the two connected ring plates 52 and the partition plate 510. A connecting pipe A55 for connecting the air inlet and air outlet ends of the two connected air ducts 512 is welded on the top of the annular plate B53, and connecting air holes are opened through the top of the annular plate B53 and at the air inlet and outlet of the connecting pipe A55.

[0033] Both sides of the air duct 512 are welded with staggered impact blocks 511. The smoke will impact the impact blocks 511. When the dust particles in the smoke collide, they will aggregate with each other due to inertial collision, electrostatic action and surface energy effect, causing the dust particles to become larger.

[0034] A speed change tube 4 is welded at the air inlet of the outermost ring plate 52, and the air inlet end of the speed change tube 4 is located outside the processing chamber 1. An air inlet chamber 3 is welded at the air inlet end of the speed change tube 4, and the air inlet chamber 3 is connected with the inlet end of the flue gas. The flue gas passes through the air inlet chamber 3 and is guided by the speed change tube 4 into the labyrinth air duct. The diameter of the air inlet chamber 3 is much larger than that of the speed change tube 4. When the large diameter enters the small diameter, the flow rate of the flue gas will increase. On the one hand, the flow rate of the flue gas will be increased, and on the other hand, the impact force of the flue gas in the labyrinth air duct will be increased.

[0035] During use, when the smoke passes through the maze-type air duct, it will pass through the interior of the air duct 512 layer by layer from the outside to the inside. When the smoke passes through the interior of the air duct 512, the smoke will collide with the impact block 511. When the dust particles in the smoke collide, due to inertial collision, electrostatic action, and surface energy effect, the dust particles will aggregate with each other, causing the dust particles to become larger and easier to be filtered out by the subsequent filter 54, thereby ensuring the dust removal effect in the smoke.

[0036] Example 2

[0037] Reference Figure 1-6 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0038] A power source 58 is welded to the inside of the innermost ring plate 52, and a scraper strip 59 for cleaning the bottom end surface of the filter 54 is installed on the top of the driving end of the power source 58. The scraper strip 59 is driven to rotate. When the scraper strip 59 rotates, it can clean the dust at the filtering point of the bottom section of the filter 54 to prevent dust from clogging the filter mesh of the filter 54, thereby ensuring the filtering efficiency of the filter 54 during long-term operation. A connecting pipe B57 is welded between the air outlet of the labyrinth air duct and the air inlet of the power source 58. The air inlet end of the connecting pipe B57 is welded to the bottom end of the annular plate A51 and is connected to the inside of the labyrinth air duct through the exhaust port 56. The air outlet end of the connecting pipe B57 is welded to the air inlet connection of the outer wall of the outer shell 582.

[0039] The power source 58 includes four welding strips 581 welded on the ring plate 52, and a shell 582 is welded between the opposite ends of the four welding strips 581. A driving shaft 584 is rotatably installed at the bottom of the inner wall of the shell 582 through a bearing, and the top end of the driving shaft 584 is located above the shell 582 and connected to the bottom end of the scraping strip 59.

[0040] An air outlet port 583 and an air inlet port are respectively formed on the outer wall of the shell 582, and a circle of convex plates 585 are welded on the lower side of the outer wall of the driving shaft 584. A connecting port 586 is formed at one end of the convex plate 585, and a wind collecting bowl 587 connected with the connecting port 586 is welded on one side of the convex plate 585. After the smoke enters the interior of the shell 582, it will pass through the connecting port 586 and hit the interior of the wind collecting bowl 587, so that the driving shaft 584 is rotated under force, and then the scraper bar 59 is driven to rotate. The scraper bar 59 is driven to rotate by the kinetic energy of the smoke, thereby realizing self-cleaning of the filter screen 54. No manual cleaning is required, which saves time and effort, and does not require electricity to reduce the cost of use.

[0041] During use, after the smoke is discharged from the maze-type air duct, it passes through the exhaust port 56 and enters the interior of the outer shell 582 under the guidance of the connecting pipe B57. After the smoke enters the interior of the outer shell 582, it will pass through the connecting port 586 and hit the interior of the wind collecting bowl 587, causing the driving shaft 584 to rotate under force, thereby driving the scraper bar 59 to rotate. When the scraper bar 59 rotates, it can clean the dust at the bottom section of the filter 54.

[0042] The remaining structures are the same as those of Example 1.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
