Abstract
This utility model relates to out of stock device, especially discloses a kind of flue and liquidates sprayer unit.The technical solution adopted in the utility model is: a kind of flue liquidates sprayer unit, cross section along flue inserts the jet pipe of flue, the part that described jet pipe inserts in flue is provided with the shower nozzle for spraying reducing agent, one end that described jet pipe is positioned at outside flue connects ultrasound atomizer, and side is provided with valve, described ultrasound atomizer and reducing agent Ye Guan UNICOM.This utility model has the advantages that denitration efficiency is high.
Description
Technical field
This utility model relates to out of stock device, especially discloses a kind of flue and liquidates sprayer unit.
Background technology
Flue liquidates, and to solve reducing agent in denitrification process short for time of contact with NOx for sprayer unit, extends the denitration reaction time, promotes that denitration reaction forward is carried out, and raising denitration efficiency, is the technique complementary of minimum discharge.Although current flue sprayer unit extends the response time to a certain extent, but it is thorough to there is also denitration reaction, and the spraying that liquidates merges halfway problem with flue gas.
Utility model content
This utility model overcomes the deficiency that prior art exists, it is provided that the flue that a kind of denitration efficiency is high liquidates sprayer unit.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is, including: the cross section along flue inserts the jet pipe of flue, the part that described jet pipe inserts in flue is provided with the shower nozzle for spraying reducing agent, one end that described jet pipe is positioned at outside flue connects ultrasound atomizer, and side is provided with valve, described ultrasound atomizer and reducing agent Ye Guan UNICOM.
So arranging, in liquid pipe, reducing agent can be atomised to less than 10 microns through described ultrasound atomizer by reducing agent, is then passed through described jet pipe and sprays from shower nozzle, forms fine and closely woven filter screen in flue, and flue gas, through out-of-date, is sufficiently mixed with flue gas, and denitration efficiency is up to 90%.
Further, multiple described jet pipes are arranged along the circular in cross-section array of flue.So arranging and reducing agent can be made to form thicker fine and closely woven filter screen in flue, flue gas, through out-of-date, necessarily collide with spraying, is sufficiently mixed, and denitration efficiency is high, and the escaping of ammonia is few.
This utility model compared with prior art has a following beneficial effect:
1. denitration efficiency is high.This utility model is first according to flue gas flow field, temperature field, and velocity field sets the speed (please write out concrete velocity interval) that reducing agent liquidates, and area coverage, to guarantee the maximally effective effect that liquidates.In liquid pipe, reducing agent can be atomised to less than 10 microns through described ultrasound atomizer by reducing agent, is then passed through described jet pipe and sprays from shower nozzle, forms fine and closely woven filter screen in flue, and flue gas, through out-of-date, is sufficiently mixed with flue gas, and denitration efficiency is up to 90%.2. arranged along the circular in cross-section array of flue by multiple described jet pipes.So arranging and reducing agent can be made to form thicker fine and closely woven filter screen in flue, flue gas, through out-of-date, necessarily collide with spraying, is sufficiently mixed, and denitration efficiency is high, and the escaping of ammonia is few.
Accompanying drawing explanation
Fig. 1 is that a kind of flue liquidates sprayer unit structural representation；
Fig. 2 is multiple jet pipe arranges schematic diagram along the circular in cross-section array of flue.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, being described in further detail detailed description of the invention of the present utility model, following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
It is illustrated in figure 1 a kind of flue to liquidate sprayer unit, including: the cross section along flue 1 inserts the jet pipe 2 of flue 1, jet pipe 2 inserts the part in flue and is provided with the shower nozzle 21 for spraying reducing agent, one end that jet pipe 2 is positioned at outside flue 1 connects ultrasound atomizer 22, and side is provided with valve 23, ultrasound atomizer 22 and reducing agent Ye Guan 3 UNICOM.
Exemplary, multiple jet pipes 2 are arranged along the circular in cross-section array of flue 1.Arranged along the circular in cross-section array of flue by multiple described jet pipes.So arranging and reducing agent can be made to form thicker fine and closely woven filter screen in flue, flue gas, through out-of-date, necessarily collide with spraying, is sufficiently mixed, and denitration efficiency is high, and the escaping of ammonia is few.
The foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
