The specific embodiment
The big sack cleaner of a kind of brick mix structure as shown in Figure 2, comprise deduster body and the gas approach 1 that is opened on the described deduster body, air-vent 2 and blowback air port 3, described deduster body is divided into flue gas mixing-chamber 4-2 by the upper face plate 11-1 and the lower face plate 11-2 of the portion of setting within it with described deduster body, operating room 5 and ash accumulating chamber 6, part is operating room 5 between described upper face plate 11-1 and the lower face plate 11-2,5 inside, described operating room are provided with the filter bag 7 that evenly is installed on upper face plate 11-1 and the lower face plate 11-2, described flue gas mixing-chamber 4-2 and ash accumulating chamber 6 lay respectively at the top and bottom of operating room 5, described deduster body is a brick mix structure deduster body, described gas approach 1 is arranged on flue gas mixing-chamber 4-2 top left side, described air-vent 2 is arranged on right side, 5 bottom, operating room, and described blowback air port 3 is arranged on 5 middle parts, operating room and is positioned at a side of air-vent 2.
As shown in Figure 2, described air-vent 2 is provided with coupled air inducing pipeline, and described blowback air port 3 is provided with coupled reverse-blow pipe road, and described air inducing pipeline is provided with air-introduced machine 8, and described reverse-blow pipe road is provided with back blowing machine 9.
As shown in Figure 2, the utility model also comprises the pure qi (oxygen) delivery pipe 10 that the lower end is connected with described air inducing pipeline, and described pure qi (oxygen) delivery pipe 10 middle and lower parts are provided with a gas outlet, and described gas outlet is connected with end, described reverse-blow pipe road.This pure qi (oxygen) delivery pipe is used to discharge the part pure qi (oxygen) after filter operating room 5.
In the utility model, described filter bag 7 is cylindric, and its cross-sectional diameter is 260mm~300mm.Cross-sectional diameter is the filter bag of 110mm~130mm in the prior art relatively, and its filter area is bigger, and filter effect is obvious.
Operation principle of the present utility model is: flue gas is entered by gas approach 1 during use, behind flue gas mixing-chamber 4-2, enter operating room 5, filter by the 7 pairs of flue gases of filter bag that are provided with in the operating room 5, impurity after the filtration falls into ash accumulating chamber 6, pure qi (oxygen) is through air inducing pipeline flow-direction pure qi (oxygen) delivery pipe 10, then most of pure qi (oxygen) is discharged from pure qi (oxygen) delivery pipe 10, be connected with end, reverse-blow pipe road owing to pure qi (oxygen) delivery pipe 10 simultaneously, therefore, when blowback wind is worked, the sub-fraction pure qi (oxygen) is sent into operating room 5 again behind back blowing machine 9, filter bag 7 is carried out reverse gas cleaning.In entire work process, aspirate by 8 pairs of flue gases of air-introduced machine, accelerated the rate of filtration of flue gas, and owing to communicate between pure qi (oxygen) delivery pipe 10 and the reverse-blow pipe road, make after filtering pure qi (oxygen) participate in during the blowback vane saves with uniform temperature.Therefore, overcome effectively not only that flue gas has guaranteed the deduster operate as normal, and avoided the flue gas reentrainment of dust that in air inducing pipeline and easy dewfall of enclosure interior and the easily fuzzy problem of filter bag promptly the dust trend is consistent with wind direction, all from top to bottom in the prior art.In addition,, effectively brought into play the resonance usefulness of air inducing and blowback wind, made easily to fall in the ash accumulating chamber 6, reduced the operation power of deduster simultaneously attached to the dust on the filter bag 7 because blowback air port 3 is positioned at 5 middle parts, operating room.
In the utility model, because the deduster body adopts brick mix structure to make, therefore, not only efficiently solve the easy problem of dewfall at work of steel construction deduster in the prior art, reduced corrosion function to filter bag, and it is slow to have heat conduction, thermal losses is little, the heat of attracting deposit is regulated the characteristics of flue-gas temperature, promptly when flue-gas temperature is lower, the heat of storage inside is discharged, reach the effect of regulating temperature, make the inner environment that forms a relative steady temperature and humidity of deduster, satisfied the demand of burning till, guaranteed the deduster operate as normal, greatly reduce cost of manufacture simultaneously, it is about 30% that its relative steel construction deduster cost reduces, and has tangible price advantage.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
