When the device works, because the coking flue gas contains various impurities and is difficult to be thoroughly separated, the coking flue gas is introduced into the desulfurizing tower 1 to be filtered before reacting with ammonia water, but the cleaning work of the filter plate 32 is difficult to be carried out in the prior art, so that the filter screen is easy to be blocked, and the working efficiency of the device is reduced, the invention filters impurities of miscellaneous families in the coking flue gas by arranging the filter plate 32, utilizes the mutual attachment of the scraper 31 and the filter plate 32 and the mutual cooperation with the adjusting mechanism 2 for use, when the filter plate 32 needs to be cleaned, the motor 216 is started, the motor 216 drives the driving block 24 and the trapezoidal block 25 to slide, the scraper 31 is driven to move, the scraper 31 scrapes the filter plate 32 and scrapes off the impurities accumulated on the outer surface of the filter plate 32, thereby being convenient for timely cleaning the filter plate 32 and preventing the filter screen from being blocked, the working efficiency of the device is improved.

As an embodiment of the present invention, as shown in fig. 7 and 8, an air blowing mechanism 4 is fixedly connected to an outer surface of the connecting cover 217;

the mechanism 4 of blowing includes fixed frame 41, trachea 42, electromagnetic pulse nozzle 43 and air pump 44, fixed frame 41 fixed connection is in the surface of connecting cover 217, the inside fixedly connected with trachea 42 of fixed frame 41, trachea 42 is close to a plurality of electromagnetic pulse nozzle 43 of one side fixedly connected with of connecting cover 217, one side through connection cover 217 that trachea 42 was kept away from to electromagnetic pulse nozzle 43 extends to the inside of connecting cover 217, one side of trachea 42 runs through fixed frame 41 and fixedly connected with air pump 44, the rear end and the desulfurizing tower 1 fixed connection of air pump 44.

In the working process, although the scraping plate 31 is arranged to scrape off impurities accumulated on the surface of the filter plate 32, because the impurity dust is adhered to the inner side and the outer side of the scraping plate 31, if the impurities are not cleaned in time, the situation that the impurities accumulated on the inner side and the outer side of the scraping plate 31 are too much and are clamped with the filter plate 32 is easily caused, and the normal use of the cleaning mechanism 3 is influenced, by arranging the swelling mechanism, when the impurities adhered on the surface of the scraping plate 31 need to be cleaned, the air pump 44 is started, and high-pressure air is sprayed out under the control of the electromagnetic pulse nozzle 43, so that the impurities adhered on the surface of the scraping plate 31 are blown off, through arranging the air blowing mechanism 4, the impurities adhered on the surface of the scraping plate 31 are conveniently cleaned, the situation that the impurities accumulated on the inner side and the outer side of the scraping plate 31 are too much and are clamped with the filter plate 32 due to the impurities adhered to the inner side and the outer side of the scraping plate 31 is not cleaned in time is avoided, the normal use of the cleaning mechanism 3 is ensured.

As an embodiment of the present invention, as shown in fig. 6 and 7, a through groove 33 is formed inside the scraper 31, the cross-sectional area of the through groove 33 is designed to be an isosceles trapezoid, and the opening diameter of the through groove 33 on the side close to the electromagnetic pulse nozzle 43 is larger.

During operation, because the gaseous of electromagnetic pulse nozzle 43 spun can only blow to scraper 31 external surface, thereby lead to the impurity of the inboard adhesion of scraper 31 to peel off difficultly, thereby lead to the impurity to pile up and take place at the inboard condition that makes scraper 31 and filter plate take place the joint of scraper 31, through seting up logical groove 33 in scraper 31 inside, and design into isosceles trapezoid structure with the cross-sectional area of logical groove 33, be convenient for make the high-pressure gas of electromagnetic pulse nozzle 43 spun pass and drop the impurity of scraper 31 external surface adhesion from logical groove 33, high-pressure gas can pass through logical groove 33 simultaneously and blow off the impurity of adhesion at scraper 31 inboard, prevent that impurity from piling up and making scraper 31 and filter plate take place the condition emergence of joint at scraper 31 internal surface.

As shown in fig. 6 and 9, in one embodiment of the present invention, a dust collecting groove 34 is formed at a lower end of the connecting cover 217, a fixing block 35 is fixedly connected to an outer surface of the lower end of the connecting cover 217 near an outer side of the dust collecting groove 34, and a dust collecting box 36 is fixedly connected to an inner surface of the fixing block 35 by a screw.

During operation, through connecting cover 217 lower extreme and setting up dust collection box 36 to connecting cover 217 and dust collection box 36 between through screw fixed connection, be convenient for dismantle dust collection box 36, thereby clear up the impurity of collecting in the dust collection box 36, prevent that the inside impurity of dust collection box 36 too much influence from entering into desulfurizing tower 1 along with second intake pipe 218 inside, the influence takes place the condition that the inside sulphide that contains of coking flue gas separates.

As an embodiment of the present invention, as shown in fig. 9, a cross section of an opening at an upper end of an inner surface of the dust collecting groove 34 is designed to be an inverted trapezoid structure, a sealing gasket 37 is fixedly connected to an outer surface of an upper end of the dust collecting box 36, a sealing groove 38 is formed at a position of a lower end of the connecting cover 217 close to the sealing gasket 37, and the sealing gasket 37 and the sealing groove 38 are attached to each other.

During operation, the dust collection box 36 is connected with the connecting cover 217 only through screws, and the air tightness of the joint of the dust collection box 36 and the connecting cover 217 is poor, so that coking smoke is easy to escape from the joint, and the health of workers is affected.

The working principle is as follows: when the invention works, firstly, the treated concentrated ammonia water is added into the desulfurizing tower 1 through the liquid inlet pipe 11, then the treated flue gas is introduced into the desulfurizing tower 1 through the first gas inlet pipe 21 and the second gas inlet pipe 218 to react with the concentrated ammonia water so as to complete the desulfurization and denitrification treatment, through the arrangement of the adjusting mechanism 2, when the flow rate of the flue gas introduced into the desulfurizing tower 1 needs to be adjusted, the motor 216 is started, the motor 216 operates to drive the turntable 215 to rotate, because the rotating rod 214 is fixedly connected with the edge position of the turntable 215, the rotating rod 214 can drive the connecting rod 212 to swing up and down when rotating along with the turntable 215, and further drive the two ends of the driving rod 20 to reciprocate back and forth, when the sliding plate 23 at the upper end slides leftwards, the sliding plate 23 at the lower end can synchronously slide rightwards, so as to drive the two groups of driving blocks 24 to slide relatively, thereby driving the four trapezoidal blocks 25 to synchronously slide, and opening the center position of the regular hexagonal groove 27, the flue gas from this entering desulfurizing tower 1, drive carousel 215 and continue to rotate as motor 216, make actuating lever 20 drive the slide 23 of upper end and slide right, and slide 23 of lower extreme slides left, thereby make two drive blocks 24 and four trapezoidal blocks 25 synchronous slip to initial position, make regular hexagon groove 27 central point put closed, in addition filter the impurity of foreign family in the coking flue gas through setting up filter 32, utilize scraper 31 and filter 32 to laminate each other, and use mutually supporting with adjustment mechanism 2, when needs clear up filter 32, starter motor 216, when motor 216 drive block 24 and trapezoidal block 25 slide, drive scraper 31 and take place to remove, scraper 31 scrapes filter 32 and will pile up the impurity of filter 32 surface and scrape away.
