Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Dust-collecting filter as depicted in figs. 1 and 2, comprises cylindrical shell 2, is provided with ball crown type end socket 9 above cylindrical shell 2, is connected with ash bucket 1 below cylindrical shell 2, offers dust outlet 18 bottom ash bucket 1; Cylindrical shell 2 outer wall top offers pure qi (oxygen) outlet 17, and cylindrical shell 2 outer wall bottom offers dust import 16; Cylindrical shell 2 is built-in with card 12, and cylindrical shell 2 inner chamber is divided into the toilet and filter chamber that distribute up and down by card 12, and toilet and pure qi (oxygen) export 17 and communicate, and filter chamber communicates with dust import 16, and toilet and filter chamber are all provided with differential pressure inductor; Card 12 hangs and is provided with cage bone 14, and cage bone 14 overcoat has filter bag 13; Cylindrical shell 2 outer wall is provided with the control cabinet 4 of pulse ash remover and control impuls deashing device, and differential pressure inductor is electrically connected with control cabinet 4, and cylindrical shell 2 outer wall is arranged with stiffening ring 15.
Pulse ash remover comprises gas storage bag 6 and is arranged on the deashing device support 5 of cylindrical shell 1 outer wall, and gas storage bag 6 is connected with electromagnetic impulse valve 7 and compressed air line 21 in turn, compressed air line 21 is provided with multiple nozzle 22, and nozzle 22 is positioned at directly over filter bag 13 opening; Gas storage bag 6 is provided with compressed air inlet 19, and electromagnetic impulse valve 7 is electrically connected with control cabinet 4; Be provided with shell flange 8 between ball crown type end socket 9 and cylindrical shell 2, ball crown type end socket 9 surface is provided with hanger 10 to ball crown type end socket 9 lifting effect and suspension rod 11; Cylindrical shell 2 outer wall is provided with the passive bearing 3 of cylindrical shell 2; Ash bucket 1 outer wall offers manhole 20.
Filtration condition: dusty gas is after entering dust import 16 and entering cylindrical shell 2, and due to the sudden enlargement of air-flow section, in air-flow, a part of big particle is moving and is being deposited in ash bucket 1 under inertia force effect; After the grit that fine size, density are little enters filter chamber, by combined effects such as Blang's diffusion and sievings, make dust deposit at filter bag 13 on the surface, purified gas enters toilet and exports 17 discharges by pure qi (oxygen).
Deashing state: the dust when filter bag 13 surface constantly increases, when causing equipment resistance to rise to setting value, differential pressure sensor output signal, the controller starting impulse deashing device in control cabinet 4.Electromagnetic impulse valve 7 is opened, gas storage bag 6 compressed air, through compressed air line 21, sprays instantaneously from nozzle 22, makes filter bag 13 dilatancy produce vibration, and under the effect of washing away at inverted draft, the dust be attached on filter bag 13 outer surface is stripped and falls into ash bucket 1.After deashing, electromagnetic impulse valve 7 is closed, and filtration condition recovers again in filter chamber.Discharged by dust outlet 18 after the dust come off falls into ash bucket 1.
This dust-collecting filter structure is simple, reasonable in design, has the advantages such as ash-removal effect is good, purification efficiency is high, process air quantity is large, life of bag filter is long, maintenance load is little, safe and reliable to operation.
