Dust-fall pipe 2 is equipped with drive shaft 11, and 11 bearing of drive shaft connects the front-rear side walls of dust-fall pipe 2, and drive shaft 11 One end be fixedly connected with the output shaft of stepper motor, drive shaft 11 is fixedly connected with two disks 12, fixed between two disks 12 Impeller 13 is connected, is fixedly connected with spray tube 14 at the top of dust-fall pipe 2,2 bottom of dust-fall pipe is fixedly connected with dust leg 15.

In the present embodiment, preceding adapter tube 1 and rear tube 3 are welded with the ring flange 16 for connecting exhaust pipe, flange The sealing surface of disk 16 uses rubber ring joint face, i.e. the sealing surface of ring flange 16 is equipped with annular groove, is embedded with seal rubber in annular groove, Ring flange 16 is easy to connect with exhaust pipe and sealing is tight.

In the present embodiment, as shown in Fig. 2, telescopic rod 6 includes round bar 601, loop bar 602, limited block 603 and elastic element 604, one end of round bar 601 is fixedly connected with the output shaft of cylinder 5, is equipped with groove at the top of loop bar 602, and round bar 601 is another End is fixedly connected with limited block 603 after protruding into groove, and elastic element 604, elastic element 604 are equipped between limited block 603 and groove For cylindrical helical pressure spring, and the upper and lower side of elastic element 604 is abutted against with limited block 603 and groove respectively, 602 bottom of loop bar Two hinge bars 7 at hinged 8 back of dust scraping plate in portion.Round bar 601 is applied forces to, round bar 601 can protrude into the recessed of loop bar 602 In slot, or loop bar 602 is applied forces to, loop bar 602 can swallow round bar 601.

In the present embodiment, as shown in figure 4, impeller 13 is formed by 36 in circumferential equally distributed curved blade, Square hole is equipped at curved blade center, square hole inner wall is fixedly connected with sieve, and the output throw of lever for working as cylinder 5 is maximum, and bullet When property element 604 is in maximum length, dust scraping plate 8 and the convex surface of curved blade are abutted against, when cylinder 5 the output throw of lever most Greatly, when and elastic element 604 is in minimum length, length of the dust scraping plate 8 away from curved blade is greater than one millimeter.Dust scraping plate 8 be to The arc-shaped rubber slab of swayback, the center of dust scraping plate are equipped with arcuation through-hole, and the width of dust scraping plate 8 is equal to the width of curved blade Degree.

In the present embodiment, nozzle is equipped in spray tube 14, for the spout of nozzle perpendicular to 13 plane of impeller, nozzle connection is solid Surely water inlet pipe is connected, water inlet pipe is fixedly connected with 14 inner wall of spray tube, and water inlet pipe is connected to effluent trough by water pump.

Working principle: exhaust pipe is disconnected, so that preceding adapter tube 1 and rear tube 3 distinguish flanged joint by ring flange 16 Ground exhaust pipe part is disconnected, so that exhaust pipe keeps clear.Circular arc leaf when there is wake flow to flow through impeller 13, on impeller 13 Under the promotion of tail gas, impeller 13 is done to be rotated piece, effect of the tail gas by rotary centrifugal force, and the diffusion stream in impeller 13 Dynamic, bulky grain such as dust adhesion are on sieve, and gaseous pollutant is then with then with tail gas outflow dust-fall pipe 2.Since tail gas pushes Impeller 13, there are a part of kinetic energy rejections for tail gas, it is possible to actively start the stepper motor being fixedly connected with drive shaft 11, make It obtains the impeller 13 under the drive of stepper motor to rotate in the forward direction, reduces tail gas kinetic energy rejection.

Sieve remaining a large amount of dust after emission, on 13 curved blade of impeller.Start cylinder 5 at this time, so that The output throw of lever of cylinder 5 is maximum, and dust scraping plate 8 and the convex surface of curved blade abut against at this time, and elastic element 604 is in and most greatly enhances Degree.

When impeller 13 reversely rotates under the drive of starting stepper motor, 13 curved blade of impeller constantly collides dust scraping plate 8, So that dust particles drop in dust leg 15, while dust scraping plate 8 applies active force to loop bar 602 so that elastic element 604 by Pressure, i.e., loop bar 602 can swallow round bar 601, and dust scraping plate 8 is not contacted with curved blade, so dust scraping plate 8 can periodicity and circular arc Blade collision, effectively hits dust in dust leg 15 down

At the same time, the nozzle opened in spray tube 14 can be synchronized, by the water droplet of nozzle atomisation, water droplet occurs Freely decline, since the spout of nozzle is perpendicular to 13 plane of impeller, water droplet and curved blade form cross-flow spray, i.e., perpendicular to Curved blade direction ejecting liquid, due to collision, interception and the cohesion between grit and water droplet, grit is with water droplet from circular arc Sieve on blade separates, and finally drops to dust leg 15, realizes cleaning impeller 13 well and recycles particulate pollutant Process has the function that tail gas depositing dust.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
