In the present embodiment, as shown in Figure 1, when under pore buttoned-up status, for making upper sealing plate 4 and realizing between lower shrouding 7 and cylindrical shell 10 sealing to prevent or the flue gas reduced in inlet flue duct 12 leaks through air inlet 11, cylindrical shell 10 inwall is welded with around the cylinder inboard wall packing ring bearing I 6 of a week and packing ring bearing II 9, packing ring bearing I 6 and packing ring bearing II 9 setting up and down, the internal diameter of packing ring bearing I 6 is greater than the internal diameter of packing ring bearing II 9, the internal diameter of packing ring bearing I 6 is less than the radius of upper sealing plate 4 and is greater than the radius of lower shrouding 7, the internal diameter of packing ring bearing II 9 is less than the radius of lower shrouding 7, the upper surface of packing ring bearing I 6 is provided with the high temperature resistant packing ring I 5 of a circle, the internal diameter of high temperature resistant packing ring I 5 is less than the radius of upper sealing plate 4 and is greater than the radius of lower shrouding 7, the upper surface of packing ring bearing II 9 is provided with high temperature resistant packing ring II 8, the internal diameter of high temperature resistant packing ring II 8 is less than the radius of lower shrouding 7, now, can pass through from high temperature resistant packing ring I 5 and packing ring bearing I 6 when upper sealing plate 4 and lower shrouding 7 move downward shrouding 7 at present, after upper sealing plate 4 and lower shrouding 7 move to packing ring bearing I 6 and packing ring bearing II 9 position respectively, sealed by high temperature resistant packing ring I 5 between upper sealing plate 4 and packing ring bearing I 6, sealed by high temperature resistant packing ring II 8 between lower shrouding 7 and packing ring bearing II 9, reach the effect of dual-seal.Wherein, high temperature resistant packing ring I 5 also can be arranged on the bottom surface of upper sealing plate 4; Same high temperature resistant packing ring II 8 also can be arranged on the bottom surface of lower shrouding 7; When high temperature resistant packing ring I 5, the thickness of high temperature resistant packing ring II 8, hardness are larger, the two also can directly be fixed on cylindrical shell 10 inwall, now can not need packing ring bearing I 6 and packing ring bearing II 9; In addition when packing ring bearing I 6 also has certain sealing effectiveness with packing ring bearing II 9 with when upper sealing plate 4 directly contacts with lower shrouding 7 respectively, certain effect is not as arranging high temperature resistant packing ring I 5 and high temperature resistant packing ring II 8.
During work, when systems are functioning properly, this glass kiln catalyst for denitrating flue gas protective device is in closed condition, pipeline I 13, pipeline II 14 cut off, and as shown in Figure 1, cylinder is in the state of stretching out, upper sealing plate 4 contacts gluing, sealing with high temperature resistant packing ring I 5 and air inlet 11 and inlet flue duct 12 is cut off, lower shrouding 7 contacts gluing, sealing with high temperature resistant packing ring II 8, and simple and compact for structure, air leak rate of air curtain is little, when system is switched to denitrating system operation by bypass operation, control system is according to flue-gas temperature, flow, temperature increase requirement, flue negative pressure, the parameters such as air themperature calculate required cooling air volume, and then the stroke calculated required for cylinder, then by exporting the signal of telecommunication or pulse signal Controlling solenoid valve 1 action, pipeline I 13 is communicated with the steam vent of magnetic valve 1 start to be vented, pipeline II 14 is communicated with compressed gas source and starts to input Compressed Gas in cylinder, cylinder starts to shrink, after putting in place, control system again Controlling solenoid valve 1 resets, pipeline I 13 is cut off and stops exhaust, pipeline II 14 is cut off stopping air inlet, cylinder stops action, as shown in Figures 2 and 3, outside air is inhaled in inlet flue duct 12 with after the flue gas hybrid cooling of inlet flue duct 12 and exports and enter Benitration reactor under the suction function of the inlet flue duct 12 of Benitration reactor, restriction Benitration reactor place flue-gas temperature raises too fast, control to allow in maximum temperature rise speed at catalyst, thus play the object of guard catalyst, when air inlet 11 and inlet flue duct 12 cut off by needs again or need to reduce incoming air area, magnetic valve 1 action, pipeline II 14 is communicated with the steam vent of magnetic valve 1 start to be vented, pipeline I 13 is communicated with compressed gas source and starts to input Compressed Gas in cylinder, cylinder starts to stretch out, after putting in place, control system again Controlling solenoid valve 1 resets.All represent the direction of motion of air in Fig. 1, Fig. 2 and Fig. 3 with solid arrow, all represent the direction of motion of flue gas with dotted arrow.In the present embodiment, the action of solenoid control cylinder, the lifting arm of cylinder drives upper and lower shrouding to move up and down in steel cylinder, and automaticity is high, on the whole simple and compact for structure, easily manufactured, automaticity is high, maintenance is little, comprehensive cost is low; Battery impulse valve selected by magnetic valve 1, controls to adjust cylinder, control more accurate by battery impulse valve signal transmission.
In addition to the implementation, the present invention also can have other embodiments, if control system is by the stroke of sensor control cylinder 3, transducing signal is sent to control system through later by lower shrouding, upper sealing plate etc. that sensor sensing connects to piston end or the piston end of cylinder 3, according to transducing signal, control system by magnetic valve 1 export the signal of telecommunication with the action of Controlling solenoid valve 1 so that realize control cylinder stop action, the optional two position two-way valve of magnetic valve 1, two position three-way valve, three position five-way valve etc., concrete model and type can be selected according to situations such as the types of cylinder, magnetic valve 1 can also be two, one with pipeline I 13 connection control pipeline I 13 break-make, another and pipeline II 14 connection control pipeline II 14 break-make, cylinder also can adopt single-acting cylinder, now the optional two position two-way valve of magnetic valve 1, cylinder 3 also available hydraulic cylinder replaces, or does not adopt cylinder 3 and magnetic valve 1 coordinate and adopt other structures such as electric pushrod, the cross sectional shape of cylindrical shell 10 is not limited only to circle, square or other shapes also, but the shape of upper sealing plate 4 should be consistent with the cross sectional shape of cylindrical shell 10, and, on the direction perpendicular to cylindrical shell 10 axis, the area of section of upper sealing plate 4 is more better close to area of section in cylindrical shell 10, namely the peripheral side wall of upper sealing plate 4 is more better close to cylindrical shell 10 inwall, therebetween gap is the smaller the better, because the gap between the wall of upper sealing plate 4 surrounding and cylindrical shell 10 inwall is less, the amount that ambient atmos enters from gap is therebetween fewer, realize by regulating the incoming air area of air inlet regulating the effect of intake better, when upper sealing plate 4 is rigid member, its circumferential side wall can also arrange outer ring that a circle flexible material makes as rubber ring, like this, upper sealing plate 4 is in motion process, rubber ring and cylindrical shell 10 contact internal walls form gapless structure, upper sealing plate 4 both can move back and forth smoothly, and air can be stoped again to enter between cylindrical shell 10 and upper sealing plate 4, those skilled in the art can also make other various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope defined in claims of the present invention.
