Abstract

The utility model discloses an improved generation ammonia air mixer, including blender casing, static mixer blade, ammonia gas inlet, the sealed end of ammonia passageway, air inlet and gas mixture export, the blender includes one, and air and ammonia are after ammonia gas inlet and air inlet get into this whirl passageway respectively by the 90 whirl passageways that constitute of adjacent static guide blade counter -clockwise turning, after the gas mixture export is discharged, single static guide blade's sectional area be blender casing sectional area half through static guide blade intensive mixing. Ammonia air mixer resistance after the improvement obviously descends, is applicable to the renovation project that dilutent fan pressure head is not enough, need not to change to dilute the fan, and the transformation expense is low, blender original relatively, the blender after the improvement have increased the quantity of small swirl, and the gas mixture passes through the whirl passageway in the blender casing, has strengthened mixed effect greatly.

Description

A kind of modified model ammonia/air mixer
Technical field
This utility model relates to a kind of modified model ammonia/air mixer, for the SCR denitration engineering that reducing agent is liquefied ammonia.
Background technology
Current existing ammonia/air mixer mostly is venturi ammonia/air mixer (also known as ejector mixing) and pipe Road static mixer, venturi mixer is common in the mixing of liquid-gas phase, liquid-liquid phase, be characterized in simple in construction, resistance little, Blender volume is little, but it is the poorest to be used in mixed effect when gas-gas mixes mutually;Pipeline static mixer adds because arranging in pipeline The guide vane of strong turbulence, mixed effect is relatively good, but its structure is complicated, and resistance is big, mixer length is longer.
Utility model content
The purpose of this utility model is to provide a kind of modified model ammonia/air mixer, is changed by pipeline static mixer Entering, make the pipeline static mixer drag reduction after improvement, mixer length reduces, and mixed effect is more preferable.
This utility model adopts the technical scheme that for solving above-mentioned technical problem:
A kind of modified model ammonia/air mixer, leads to including mixer case, static mixer blades, ammonia entrance, ammonia Road sealed end, air intake and mixed gas outlet, described blender includes that one is rotated counterclockwise by neighboring static guide vane 90 ° of swirl channel constituted, air and ammonia are after ammonia entrance and air intake respectively enter this swirl channel, by static state Guide vane is discharged through mixed gas outlet after being sufficiently mixed, and the sectional area of single static guide vane is mixer case sectional area Half.
Further, described swirl channel is formed by neighboring static guide vane half-twist counterclockwise.
Further, a length of 180mm-280mm of described static guide vane.
Further, a diameter of 350mm-550mm of described mixer case.
Further, in described mixer case, the flow velocity of mixed gas is 5-8m/s.
The beneficial effects of the utility model are: the ammonia after improvement/air mixer resistance is decreased obviously, it is adaptable to dilution wind The transformation project that compressing head is not enough, it is not necessary to changing dilution air, improvement expenses is low;The most original blender, the mixing after improvement Device adds the quantity of small whirlpool, and gaseous mixture, by the swirl channel in mixer case, greatly strengthen mixed effect.
Accompanying drawing explanation
Fig. 1-3 is the schematic diagram of existing conventional pipeline static mixer;
Fig. 4-9 is structural representation of the present utility model.
Detailed description of the invention
Detailed description of the invention of the present utility model is:
A kind of modified model ammonia/air mixer, as shown in figures 4-9, including mixer case 1, static mixer blades 2, Ammonia entrance 3, ammonia channel seal end 4, air intake 5 and mixed gas outlet 6, described blender includes one by neighboring static The swirl channel of half-twist composition that guide vane is counterclockwise, air and ammonia respectively enter this through ammonia entrance and air intake After swirl channel, discharge through mixed gas outlet after being sufficiently mixed by static guide vane, the cross section of single static guide vane Amass the half for mixer case sectional area.
Described swirl channel is formed by neighboring static guide vane half-twist counterclockwise.
The a length of 180mm-280mm of described static guide vane.
A diameter of 350mm-550mm of described mixer case.
In described mixer case, the flow velocity of mixed gas is 5-8m/s.
In one embodiment, blender of the present utility model compares existing conventional blender (as Figure 1-3) Add mixer case diameter, reduce velocity of medium in blender, flow velocity in mixer case is down to the interval of 5 to 8m/s Scope, thus reduce the drag losses of pipeline static mixer;Neighboring static guide vane is counterclockwise half-twist, forms eddy flow Passage, strengthens the mixed effect of ammonia and air;Increase static mixer blades length, increase single static guide vane afterbody micro- The quantity of little whirlpool, strengthens mixed effect;Single blender blade sectional area is the half that housing section is long-pending, whole housing and shell Must not there be crack, pore, arc crater and macroscopic defect in the commissure of internal parts junction, and removes slag and splashing Thing.
Ammonia after improvement/air mixer resistance is decreased obviously, it is adaptable to the transformation project that dilution air pressure head is not enough, nothing Need to change dilution air, improvement expenses is low;The most original blender, the blender after improvement adds the quantity of small whirlpool, Gaseous mixture, by the swirl channel in mixer case, greatly strengthen mixed effect.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification, these change Enter and also should be regarded as protection domain of the present utility model with modification.
