Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than all
Embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, belongs to the scope of the utility model protection.
Fig. 1-3 be refer to there is provided a kind of cold air input unit being useful on flue gas mixed pipe line, it includes a confession
The chamber 1 on flow of flue gas path in the flue gas mixed pipe line is located at, the chamber 1 includes outer wall 12 and inwall 11, in institute
State at least provided with a cold air entrance 2 communicated with the chamber 1 on outer wall 12, multiple cold airs are provided with the inwall 11
Jet pipe 3, one end of each cold air jet pipe 3 is communicated in the chamber 1, and the other end of each cold air jet pipe 3 is communicated in
The flue gas mixed pipe line, and the multiple cold air jet pipe 3 be spaced on the inwall 11 to be formed successively with the cigarette
Flow of air path perpendicular the first orifice layer of cold air 31 and the second orifice layer of cold air 32.
The operation principle of above-mentioned cold air input unit is, cold air is inputted from cold air entrance 2, allows cold air to enter
Mouth 2 is passed through after Uniform Flow in chamber 1 and is delivered to by cold air jet pipe 3 in flue gas mixed pipe line, so that cold air and flue gas
Flue gas in mixed pipe line is mixed, because cold air passes sequentially through the first orifice layer of cold air 31 on flow of flue gas path
Multi-level output is realized with the second orifice layer of cold air 32, and in the first orifice layer of cold air 31 or the jet pipe of cold air second
Layer 32 includes multiple cold air jet pipes, can so form turbulence structure in machine and transverse direction, it is ensured that cold air and cigarette
Gas is sufficiently mixed.
In specific implementation, because flue gas mixed pipe line is generally pipe, therefore, formed by outer wall 12 and inwall 11
Chamber 1 can be a loop configuration, i.e., chamber 1 can be so socketed on flue gas mixed pipe line by one annular compartment.Ring
Shape chamber can ensure that the cold air of input has uniform resistance on inwall 11 and outer wall 12, beneficial to the quick stream of cold air
It is dynamic.
Specifically, the inwall 11 of chamber 1 can be used as with the surface where flue gas mixed pipe line, pass through outer wall 12 and flue gas
Weld to form the chamber 1 of a closing between surface where mixed pipe line.Of course, the outer wall 12 of chamber 1 can not
Such as with also circularizing, it can also make other shapes, square.
In specific implementation, the length of each cold air jet pipe is sprayed not less than cold air first in the second orifice layer of cold air 32
The length of each cold air jet pipe in tube layer 31.That is, on the flow of flue gas path, in the cold of flow of flue gas upstream
The length of each cold air jet pipe is smaller than or equal to the cold air in flow of flue gas downstream where the first orifice layer of gas 31
The length of each cold air jet pipe where second orifice layer 32.Specifically, each cold air jet pipe where the second orifice layer of cold air 32
Length can be 1.0-1.5 times of the length of each cold air jet pipe where the first orifice layer of cold air 31.
In addition, the length of each cold air jet pipe needs to control 0-0.4 times of the internal diameter where flue gas mixed pipe line, so may be used
With the contact range of effective cold air and flue gas, if the length of cold air jet pipe is long to cause the contact surface of cold air and flue gas
It is smaller；And if the too short mixing that can cause cold air and flue gas of the length of cold air jet pipe is uneven.
In specific implementation, cold air cant of the jet is located on inwall 11, i.e. the caliber of cold air jet pipe and inwall 11
Vertical direction has certain angle, specifically, the scope of the angle can be between 15 ° -45 °, it is of course also possible to be equal to
15 ° or 45 °.By the way that cold air cant of the jet is located on inwall 11 cold air can be allowed to form eddy flow, so that more conducively gas
Mixing.
In addition, the incline direction of the place cold air jet pipe of the first orifice layer of cold air 31 can be with the orifice layer of cold air second
32 cold air jet pipe incline direction it is opposite.So as to form turbulence structure staggeredly, more conducively between flue gas and cold air
Mixing.
In specific implementation, inwall 11 and outer wall 12 where chamber 1 are metal material.
Further, Fig. 4 is may refer to, is a kind of application of the cold air input unit on flue gas mixed pipe line, is such as schemed
Shown, cold air input unit is located on one end of flue gas mixed pipe line 4, flue gas mixed pipe line input flue gas by with cold air
Enter back into dirty after body phase mixing, cold air input unit provided by the utility model can ensure the equal of flue gas and cold air
Even mixing, provides the foundation, and then advantageously reduce the application cost of equipment for dirty flue gas mixing.
Above-mentioned specific embodiment only illustrative principle of the present utility model and its effect, not for limiting this practicality
It is new.Any person skilled in the art can all enter without prejudice under spirit and scope of the present utility model to above-described embodiment
Row modifications and changes.Therefore, such as those of ordinary skill in the art without departing from disclosed in the utility model
Spirit and all equivalent modifications completed under technological thought or change, should be covered by claim of the present utility model.
