The object of the invention is to have come by following technical solution, a kind of denitration device for industrial smoke, it comprises a Benitration reactor, described Benitration reactor is one built with the tubular reactor body of catalyst, the external admission line in upper end of described reactor body, lower end picks out feed channel, a controlled pipeline is serially connected with between admission line and outlet pipe, flue gas tube connector is connected at the mesophase spherule of this controlled pipeline, the upper and lower controlled pipeline being positioned at flue gas tube connector is respectively arranged with into gas fume valve and in line gas fume valve, to control flue gas and enter reactor body from admission line or control flue gas by line gas fume valve by entering gas fume valve and directly taken out of by external blower fan from outlet pipe.
Described enter on admission line between gas fume valve and reactor body or controlled pipeline to be provided with an ammonia-gas spraying device, this ammonia-gas spraying device is communicated with the ammoniacal liquor pond of peripheral hardware; Be provided with at least three layers of grid in described reactor body, between grid, be filled with the catalyst that mainly can remove hydroxide between two.
Described ammonia-gas spraying device be one with atomizing pump grid baffle plate or be shaped with aerosol through hole baffle plate form, wherein said baffle plate is fixed in the middle of tube chamber, atomizing pump is provided with on the ammonia water pipe outside tube chamber, and make ammoniacal liquor formed after the eruption of described atomizing pump atomization ammonia enter mix with flue gas in tube chamber after enter in reactor body as reducing agent.
The invention belongs to and improve the one of prior art, it is simple that it has structure, uses easy to operate, the features such as denitration effect is good, and equipment investment is little, and use cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, a kind of denitration device for industrial smoke of the present invention, it comprises a Benitration reactor, described Benitration reactor is one built with the tubular reactor body 2 of catalyst 1, the external admission line 3 in upper end of described reactor body 2, lower end picks out feed channel 4, a controlled pipeline 5 is serially connected with between admission line 3 and outlet pipe 4, flue gas tube connector 6 is connected at the mesophase spherule of this controlled pipeline 5, the upper and lower controlled pipeline 5 being positioned at flue gas tube connector 6 is respectively arranged with into gas fume valve 7 and in line gas fume valve 8, to control flue gas and enter reactor body 2 from admission line 3 or control flue gas by line gas fume valve 8 by entering gas fume valve 7 and directly taken out of by external blower fan from outlet pipe 4.
Shown in figure, of the present inventionly enter admission line 3 between gas fume valve 7 and reactor body 2 or controlled pipeline 5 are provided with an ammonia-gas spraying device, this ammonia-gas spraying device ammonia water pipe 9 is communicated with the ammoniacal liquor pond of peripheral hardware; Be provided with at least three layers of grid 10 in described reactor body 2, between grid 10, be filled with the catalyst 1 that mainly can remove hydroxide between two.
Ammonia-gas spraying device of the present invention be one with atomizing pump 11 grid baffle plate 12 or be shaped with aerosol through hole baffle plate form, wherein said baffle plate 12 is fixed in the middle of tube chamber, atomizing pump 11 is provided with on the ammonia water pipe 9 outside tube chamber, and make ammoniacal liquor formed after the eruption of described atomizing pump 12 atomization ammonia enter mix 13 with flue gas in tube chamber after enter in reactor body 2 as reducing agent.
The present invention is connected to the fume emission mouth of Industrial Stoves by flue gas tube connector 6, by monitoring, if do not had in flue gas or a small amount of hydroxide, then can by opening in line gas fume valve 8, closing into gas fume valve 7, now flue gas can be discharged by external blower fan by controlled pipeline 5, outlet pipe 4 or enter in other purifier.
