The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figures 1 to 4, dust arrester installation with flow-guiding structure, comprise support 1, casing 2, blowing device 3, filter bag 7 and control device, filter bag 7 is located in casing 2, the side of case 2 bodies is respectively equipped with air inlet 10 and air outlet 9, and casing 2 lower ends are connected with ash bucket 15, is provided with ash-discharging device 4 below ash bucket 15, described control device comprises PLC Programmable Logic Controller and pulse control instrument, and the PLC Programmable Logic Controller is connected with pulse control instrument and described blowing device 3 circuit; Described blowing device 3 be arranged on casing 2 above, blowing device 3 is connected with air compression plant by pipeline; Be provided with air intake passage between described air inlet 10 and air outlet 9, air intake passage is provided with volume damper 12, and casing 2 is provided with air intake passage switching mechanism 6.
Be provided with two rows water conservancy diversion flaggy in described ash bucket 15, the quantity of upper strata deflector 8 is less than the quantity of lower floor's deflector, and the tip of all deflectors 8 arranges and arrange the formation zigzag up.Described deflector 8 is made after bending by surface plate, and surface plate is made as hexagonal structure, has some pod apertures 81 on surface plate; The both sides up and down of surface plate are parallel to each other and equate, all the other of surface plate four limits equate and less than the length on both sides, surface plate up and down, surface plate Formation cross-section after the center line doubling is the deflector of equilateral acuter angles, the acute angle that deflector forms after the center line doubling greater than 45 degree less than 60 degree.
In the present embodiment, described air inlet 10 is connected with ash bucket 15, and ash bucket 15 is connected with described ash-discharging device 4, and the described ash-discharging device of the present embodiment is the automatic ash-discharging device conveying worm.Described blowing device 3 comprises injection tube, nozzle and magnetic valve, and magnetic valve is located on injection tube and with described pulse control instrument circuit and is connected, and the described pulse control instrument of the present embodiment comprises Pressure difference feedback formula pulse control instrument.Described filter bag 7 upper ends are connected with filter bag installing rack 14, and connection is connected in filter bag 7 lower ends with the filter bag locating rack, and described ash bucket 15 outer walls are provided with hopper wall vibrator, to strengthen the effect of deashing.Also be provided with staircase platform 5 above described casing 2, staircase platform 5 is provided with air intake passage switching mechanism 6.
