Description
Technical field
The utility model relates to a kind of supporting denitrification apparatus for Industrial Stoves, belong to technical field of environment protection equipment.
Background technology
Existing Industrial Stoves, can produce a large amount of flue gases containing nitrogen oxide, this flue gas enters air can form acid rain, increases haze weather, very large to mankind's harm.The Industrial Stoves of some routines at present, more even as coal-burning boiler etc. can produce the industrial equipment of flue gas, all can consider to configure denitrification apparatus, or configuration consists predominantly of the flue gas purifying equipment of denitrification apparatus, so that by the purified treatment of flue gas, reach objects such as eliminating nitrogen oxide.But the flue gas purifying equipment structure that existing large-scale industrial equipment is equipped with is all comparatively complicated, this baroque flue gas purifying equipment is mainly in order to improve the effect of purifying smoke, and therefore corresponding input is also large, thus adds the use cost of equipment.For the Industrial Stoves of some miniaturizations, because the exhaust gas volumn produced is little, the purifier structure of outfit is simple, so the effect often removing nitrogen oxide is just poor.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of structure simple, and use easy to operate, denitration effect is good, and equipment investment is little, the supporting denitrification apparatus for Industrial Stoves that use cost is low.
The purpose of this utility model has been come by following technical solution, a kind of supporting denitrification apparatus for Industrial Stoves, 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 utility model belongs to and improves the one of prior art, and 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 utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of supporting denitrification apparatus for Industrial Stoves described in the utility model, 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, described in the utility modelly 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 described in the utility model 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 utility model 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.
Normal denitrification process is: flue gas is accessed by flue gas tube connector 6, enters controlled pipeline 5 by entering gas fume valve 7, entering in reactor body, by removing the nitre in flue gas after catalytic reaction, and drawing from the outlet pipe 4 of bottom after mixed with vaporific ammonia.The ammonia that ammoniacal liquor described in the utility model ammoniacal liquor evaporation after ammonia-gas spraying device becomes atomization shape mixes as reducing agent and flue gas and enters in reactor body and participates in denitration reaction.
