Referring to fig. 1-4, the present invention provides a technical solution:

a flue gas preprocessor with a detachable dust bin comprises a dust bin 1 and a water cooling box 2, wherein the top end of the dust bin 1 is provided with a first connecting pipe 11 communicated with the inside of the dust bin 1, the left side lateral wall of the water cooling box 2 is provided with a smoke inlet pipe 21, one end of the smoke inlet pipe 21 penetrates through the water cooling box 2 and extends out from the top end of the water cooling box 2, one end of the smoke inlet pipe 21 positioned above the water cooling box 2 is tightly connected with the first connecting pipe 11 through a flange 12, at least two filter screen frames 4 are arranged inside the dust bin 1, filter screens are tightly bonded in the filter screen frames 4, the filter screen frames 4 are embedded in the dust bin 1, the inner wall of the right end of the dust bin 1 is positioned above the filter screen frames 4 and fixed with a fixing plate 5 through bolts, the bottom surface of the fixing plate 5 is tightly bonded with a dust removing brush 51, the right side wall of the dust bin 1 is positioned below the lowest filter screen frame 4 and is also provided with a second connecting pipe 13 communicated with the inside of the dust bin 1, one end of the second connecting pipe 13, which is far away from the dust bin 1, is also connected with a smoke outlet pipe 14 through a flange 12, a dust exhaust pipe 15 is arranged in the middle of the bottom surface of the dust bin 1, and a valve 151 is arranged on the dust exhaust pipe 15.

In this embodiment, the quantity of filter screen frame 4 is two at least, and the mesh of the filter screen in the filter screen frame 4 of lower floor is littleer than the mesh of the filter screen frame 4 of upper strata, and what can be better filters and intercepts the dust, has ensured that can be better carries out the smoke detection.

Specifically, be equipped with outline 41 on the right side wall of filter screen frame 4, outline 41 and filter screen frame 4 are the integrated into one piece structure, and close welding has slider 42 on the wall of filter screen frame 4's the both sides around, set up the spout with slider 42 looks adaptation on the both ends inner wall around dust storehouse 1 for filter screen frame 4 can take out and inlay the inside of locating dust storehouse 1, has effectively alleviateed the step when changing filter screen frame 4, has alleviateed staff's working strength.

Further, the rubber blocks 43 with the same cross section as the sliding blocks 42 are tightly bonded on the side walls of the front end and the rear end of the outer frame 41, and the handle 44 is tightly welded in the middle of the side wall of the right end of the outer frame 41, so that smoke cannot be discharged through a gap between the sliding blocks 42 and the sliding grooves, and the tightness of the device is ensured.

Furthermore, the cross section of the outer frame 41 is isosceles trapezoid, a through groove matched with the outer frame 41 is formed in the right side wall of the dust bin 1, and a rubber layer is tightly bonded to the upper inclined surface and the lower inclined surface of the outer frame 41, so that the smoke is further prevented from being discharged from the through groove, and the air tightness of the device is reflected.

Besides, still be equipped with a scavenge pipe 3 in the water-cooling tank 2, wherein one end of scavenge pipe 3 passes water-cooling tank 2 and stretches into the inside to dust storehouse 1, the one end threaded connection that scavenge pipe 3 is located 1 inside in dust storehouse has shower nozzle 31, water-cooling tank 2 is used for cooling for entering into the flue gas in the dust storehouse 1 through advancing tobacco pipe 21, prevent the flue gas from reburning, and can also clear up after dust is accepted for a long time in dust storehouse 1 through scavenge pipe 3 and shower nozzle 31, the cleanness after dust storehouse 1 long-term work has been ensured.

Further, the nozzle 31 is located above the uppermost filter screen frame 4 inside the dust bin 1, so that the dust bin 1 and the filter screens can be cleaned in all directions.

Further, the bottom inner wall in dust storehouse 1 is the round platform type for when discharge dust and clearance water, dust and clearance water can not remain in the dust storehouse 1.

It should be noted that a water pump is further installed in the water cooling tank 2, and a water outlet of the water pump is in threaded connection with one end of the cleaning pipe 3 located in the water cooling tank 2, and is used for providing power for cleaning the interior of the dust bin 1.

When the flue gas preprocessor with the detachable dust bin is used, flue gas to be detected enters the first connecting pipe 11 from the smoke inlet pipe 21 and finally enters the dust bin 1, in the process, the water cooling box 2 cools the flue gas in the smoke inlet pipe 21, in the dust bin 1, the flue gas is filtered by at least two layers of filter screens, dust in the flue gas is remained in the dust bin 1, the flue gas is finally discharged into a subsequent flue gas treatment box through the second connecting pipe 13 and the smoke outlet pipe 14, after long-term flue gas preprocessing, a large amount of dust is accumulated on the dust bin 1 and the filter screens, at the moment, the handle 44 is held, the filter screen frame 4 is pulled outwards, in the pulling process, the dust on the filter screens is cleaned by the dust removing brush 51, the cleaned dust directly falls into the bottom end of the dust bin 1, and when the dust in the dust bin 1 is accumulated too much, open the power of water pump, the water in the water-cooling box 2 just can circulate to shower nozzle 31 department through scavenge pipe 3, is cleared up the inside in dust storehouse 1 by shower nozzle 31 at last, and the clearance finishes, opens valve 151, and waste water and dust just can discharge through dust exhaust pipe 15, have solved because contain more dust in the flue gas, after carrying out longer time's work, all can pile up more dust on the filter equipment in the dust storehouse, seriously influence the problem of subsequent work.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
