Description
The technical field is as follows:
the utility model discloses the creation belongs to msw incineration gas cleaning field, relates to the sack cleaner, specifically is a system of high-efficient desorption msw incineration flue gas dust and dioxin.
Background art:
at present, the technology of 'activated carbon injection + bag-type dust remover' is widely adopted for removing dioxin in flue gas of a waste incineration power plant, although the method has a good effect of removing the dioxin, the consumption of the activated carbon is high, the operation cost is high, and because one part of the dioxin is adsorbed on fly ash particles and the other part of the dioxin exists in the flue gas in a gas phase suspension mode, the adsorption effect of the activated carbon on the gaseous suspended dioxin is not ideal because of the influence of the fly ash, heavy metals and the like in the flue gas. Meanwhile, the inlet of the conventional bag-type dust collector has an obvious jet phenomenon, which can cause uneven airflow in the dust collector, generate great impact on the filter bag, reduce the dust collection efficiency and shorten the service life of the filter bag.
The invention content is as follows:
the utility model aims at providing a device of high-efficient desorption msw incineration flue gas dust and dioxin can improve the dioxin desorption effect, reduces the active carbon quantity, reduces the running cost, extension filter bag life.
The utility model discloses at prior art's compressed air tank (1), jetting pipe (2), solenoid valve (3), sealed card (4), box (6), and compressed air tank (1.1), jetting pipe (2.2), solenoid valve (3.3), sealed card (4.4), box (6.6), characterized by establishes ties two sack cleaner (13 and 14) with the form of one-level and second grade, be at one-level and second grade sack cleaner flue gas inlet channel back equipartition put guide plate (7 and 7.7), export (11) and locate to set up active carbon injection apparatus (12) at one-level sack cleaner (13).
The utility model discloses a guide plate (7 and 7.7) are evenly arranged at the back at one-level and second grade sack cleaner flue gas inlet channel, and the guide plate slope is arranged.
The utility model is provided with a through hole in the guide plate.
Above the utility model discloses the height of guide plate increases along flue gas flow direction gradually.
The radius of the blunt body attached on the guide plate of the utility model is gradually reduced along the flowing direction of the flue gas.
Compared with the prior art, the utility model adopts the above technical scheme have following technological effect:
1. the guide plate is arranged at the back of the flue gas inlet, so that the air flow in the bag-type dust remover is distributed more uniformly, the dust removal efficiency is improved, the washing of jet flow to the filter bag is reduced, and the service life of the bag is prolonged.
2. The first-stage bag-type dust collector and the second-stage bag-type dust collector are connected in series, the activated carbon is sprayed at the smoke outlet of the first-stage bag-type dust collector, the fly ash, the solid-phase dioxin and the heavy metal attached to the fly ash are removed by the first-stage bag, the gas-phase dioxin then penetrates through the first-stage bag and is mixed with the activated carbon, the activated carbon sprayed at the outlet of the first-stage bag can more effectively adsorb the gas-phase dioxin without interference of particles such as the fly ash, the removal efficiency of the dioxin and the heavy metal is greatly improved, and the. Meanwhile, as the particulate matters and the like are removed by the primary cloth bag, the clean active carbon is discharged when the secondary cloth bag is used for removing ash, so that the active carbon can be recycled, and the operation cost is reduced.
Description of the drawings:
fig. 1 shows a schematic view of the overall structure of the present invention.
The specific implementation mode is as follows:
according to fig. 1, the utility model discloses at prior art's compressed air jar 1, jetting pipe 2, solenoid valve 3, sealed card 4, box 6 to and compressed air jar 1.1, jetting pipe 2.2, solenoid valve 3.3, sealed card 4.4, on box 6.6's the basis, the utility model discloses especially establish ties two sack cleaner 13 and 14 with the form of one-level and second grade, at one-level 13 and second grade sack cleaner 13.13 flue gas inlet channel 8 and 8.8 back equipartition device guide plate 7 and 7.7, export 11 department at one-level sack cleaner 13 and set up active carbon injection apparatus 12.
The utility model discloses at one-level 13 and second grade cloth dress dust remover 13.13 flue gas inlet channel 8 and 8.8 at the back equipartition device guide plate 7 and 7.7, the guide plate slope is arranged. The guide plate is provided with a through hole, the height of the guide plate is gradually increased along the flow direction of the flue gas, and the radius of the guide plate attached with the bluff body is gradually reduced along the flow direction of the flue gas.
The utility model discloses a basic operating principle and work flow:
the waste incineration flue gas gets into from one-level sack cleaner 13 flue gas inlet flue 8, passes filter bag 5 through water conservancy diversion baffle 7 and flows from bottom to top, and the particulate matter is filtered by filter bag 5 and forms the dust layer, and along with the increase of time, the adnexed dust granule in filter bag 5 top layer is more and more, needs carry out the deashing to the filter bag this moment. The pulse ash cleaning system is used for cleaning ash through periodic or constant pressure control, when the ash cleaning work is carried out, particles fall off from the surface layer of the filter bag and enter the ash hopper 10, and fly ash in the ash hopper 10 is discharged to the ash conveying system through the ash discharge valve 9. Dust in the flue gas and the dioxin and the heavy metal that adsorb on the dust are got rid of through one-level sack cleaner 13, and the clean gas after the filtration is through 13 exhanst gas outlet channel 11 of one-level sack cleaner and active carbon intensive mixing of one-level sack cleaner, gets into second grade sack cleaner 13.13 from second grade sack cleaner 13.13 flue gas inlet channel 8.8, gets rid of active carbon particle and the dioxin and the heavy metal that adsorb on through same principle. Because the dust and the dioxin and heavy metal attached to the dust are removed by the primary bag-type dust collector 13, the activated carbon sprayed from the outlet of the primary bag-type dust collector 13 can more effectively adsorb the dioxin and the heavy metal without interference of particles such as fly ash, the removal efficiency of the dioxin and the heavy metal is greatly improved, and the using amount of the activated carbon is reduced. Meanwhile, as the particulate matters and the like are removed by the primary bag-type dust remover 13, the secondary bag-type dust remover 13.13 removes dust by taking off relatively clean active carbon, the active carbon can be recycled, and the operation cost is reduced.
