Description
Technical field
The present invention relates to denitration technology, be specifically related to a kind of ammonia dilution mixture current equalizer.
Background technology
The strict propelling required air contaminant treatment along with country, the enterprise that many fume emission total amounts are little takes off at NOx
Also control has been carried out except aspect.But the finished product reductant concentration because directly buying is high, reducing agent use measuring instrument and
There is bigger difficulty during injection apparatus type selecting, there is puzzlement in the enforcement to engineering.It is thus desirable to first the ammonia of high concentration is carried out
Dilution, improves the metering accuracy of system, to reach higher denitration efficiency.
At present, most process system is the ammonia of the high concentration directly fresh water (FW) and the reducing agent storage tank of dilution storage tank come
Water is injected in ammonia conveyance conduit together by respective induction system, conventional inlet channel be simply provided with technique water pump and
, there is its outlet pressure and be more than ammonia outlet pressure, cause ammonia to be suppressed and can not enter reduction continuously and stably in flow control valve
Agent reaction zone so that nitrogen oxides discharges exceed standard because reducing agent consumption can not meet working condition requirement.
Summary of the invention
The technical problem to be solved is, for the deficiencies in the prior art, it is provided that a kind of ammonia dilution mixture
Current equalizer, simple in construction, easy processing, cost of manufacture is low, can efficiently complete SNCR+SCR composite denitration reducing agent and add.
The present invention solves the technical scheme that its technical problem is used, before inlet channel, ammonia-feeding pipe road, mixing tube
Section, induction tunnel, mixing tube flow equalization section, spreader, crisscross fixer, helical blade.
Mixing tube leading portion, induction tunnel, mixing tube flow equalization section constitute technique dilution water and the mixing duct of reducing agent, Qi Zhongyin
Penetrate the diameter of pipe less than mixing tube leading portion and the diameter of mixing tube flow equalization section.
Ammonia-feeding pipe road and inlet channel are arranged on mixing tube leading portion, and ammonia-feeding pipe road is perpendicular to mixing tube axis and installs, water inlet
Pipeline and mixing tube are co-axially mounted, and inlet channel is cone-shaped in mixing tube, and length extends mixing tube leading portion end.
Mixing tube flow equalization section bellend has crisscross fixer, middle part to be provided with spreader, is provided with 4 height in straight length
Being the helical blade of 20～30mm, helical blade and straight length angle are 10 °～15 °.
The present invention is according to the big feature of denitrating technique dilution water amount ratio reducing agent consumption, using fresh water (FW) as main flow, also
Former dose is flowed as secondary, and fresh water (FW) flow at high speed leads ammonia to pass through induction tunnel, and under induction tunnel effect, reducing agent flows into mixed smoothly
Close pipe flow equalization section to carry out mixing current-sharing, be then fed into conversion zone.
During work, technique dilution water and and after high strength ammonia water respectively enters inlet channel and ammonia-feeding pipe road, at induction tunnel
Under the drive of section high-speed process dilution water flow, high concentration ammonia enters injection pipeline section the most smoothly, another entrance mixing tube current-sharing
Section, after being arranged on the helical blade in the spreader of mixing tube flow equalization section bellend and mixing tube flow equalization section straight length, two
Plant liquid and obtain good mixing current-sharing.
The beneficial effects of the present invention is: reducing agent dilution technique flow process is simple, control stable, mix current equalizer structure
Simply, easy processing, cost of manufacture is low, it is not necessary to power source, can efficiently complete current-sharing mixing, efficiently solve reducing agent stream
The unstable phenomenon of amount, does not haves reducing agent and is suppressed and cause NOx emission to exceed standard phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure, 1 be inlet channel, 2 for ammonia-feeding pipe road, 3 for mixing tube leading portion, 4 for induction tunnel, 5 for mixing tube flow equalization section,
6 be spreader, 7 be crisscross fixer, 8 for helical blade.
Detailed description of the invention
Below in conjunction with the accompanying drawings and be embodied as that the invention will be further described.
This specific embodiment provides a kind of ammonia dilution mixture current equalizer, including inlet channel 1, ammonia-feeding pipe road 2, mixing
Pipe leading portion 3, induction tunnel 4, mixing tube flow equalization section 5, spreader 6, crisscross fixer 7, helical blade 8.
Mixing tube leading portion 3, induction tunnel 4, mixing tube flow equalization section 5 constitute the mixing duct of technique dilution water and reducing agent, its
The diameter of middle induction tunnel 4 is less than mixing tube leading portion 3 and the diameter of mixing tube flow equalization section 5.
Ammonia-feeding pipe road 2 and inlet channel 1 are arranged on mixing tube leading portion 3, and ammonia-feeding pipe road 2 is perpendicular to mixing tube axis and installs,
Inlet channel 1 and mixing tube are co-axially mounted, and inlet channel 1 is cone-shaped in mixing tube, and length extends the end of mixing tube leading portion 3
End.
Mixing tube flow equalization section 5 bellend has crisscross fixer 7, and middle part is provided with spreader 6, is provided with 4 in straight length
Being highly the helical blade 8 of 30mm, helical blade 8 and straight length angle are 15 °.
The present invention is according to the big feature of denitrating technique dilution water amount ratio reducing agent consumption, using fresh water (FW) as main flow, also
Former dose is flowed as secondary, and fresh water (FW) flow at high speed leads ammonia to pass through induction tunnel, and under induction tunnel effect, reducing agent flows into mixed smoothly
Close pipe flow equalization section to carry out mixing current-sharing, be then fed into conversion zone.
During work, technique dilution water and and after high strength ammonia water respectively enters inlet channel 1 and ammonia-feeding pipe road 2, at injection
Under the drive of pipe 4 high-speed process dilution water flow, high concentration ammonia enters induction tunnel 4 the most smoothly, another entrance mixing tube current-sharing
Section 5, by being arranged on the helical blade 8 in the spreader 6 of mixing tube flow equalization section 5 bellend and mixing tube flow equalization section 5 straight length
After, two kinds of liquid have obtained good mixing current-sharing.
