Description
Technical field
The utility model relates to a kind of accurate ammonia spray equipment for very-short-reach mixing.
Background technology
Existing ammonia sprinkling equipment has several form, such as arrange spray column to spray, but this kind of spray equipment of planting complexity needs to carry out special circuit design, pending gas is introduced in spray equipment, and the setting direction of nozzle mostly is reverse in spray equipment, namely facing to the direction of air-flow, also the nozzle direction of part spray equipment is had to be forward, the ammonia flow of ejection is consistent with pending airflow direction, these two kinds spray directions all need ammonia can be made fully to mix with pending gas through longer path, cause spray equipment must have longer flow process and larger volume thus, the occasion of this spray equipment cannot be used for the restriction having structure or place because of pipeline, need to develop one and just can realize ammonia and the well-mixed ammonia spray equipment of pending gas in short distance or very-short-reach.
Utility model content
In order to overcome the above-mentioned defect of prior art, the utility model provides a kind of accurate ammonia spray equipment for very-short-reach mixing, and this spray equipment can realize mixing of ammonia and pending gas in very short distance, and Ei structure is simple, easy and simple to handle, mix, resistance is little.
The technical scheme that the utility model adopts: a kind of accurate ammonia spray equipment for very-short-reach mixing, comprise the female pipe of spray and spray arm, the quantity of described spray arm is multiple, described multiple spray arm is connected on the female pipe of described spray mutually side by side, the female pipe of described spray is positioned at outside gas passage, described spray arm is from described gas passage extension in described gas passage, described gas passage is vertical passageway, the described multiple spray arms being positioned at described gas passage are distributed in same level, the described multiple spray arms being positioned at described gas passage are equipped with nozzle, the injection direction of described nozzle is horizontal direction.
The beneficial effects of the utility model: owing to have employed the nozzle of horizontal-jet, and multiple spray arm is arranged in the same level of vertical gas passage, make the ammonia that ejects can the whole cross section of blanketing gas passage thus, fully contacting of ammonia and pending gas just can be realized in very short distance, and airflow direction in vertical gas passage is mutually vertical with the ammonia flow direction of ejection, also be conducive to the disturbance strengthening gas, improve mixed effect between the two further.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model;
Fig. 2 is the side-looking structural representation corresponding with Fig. 1.
Detailed description of the invention
See Fig. 1 and Fig. 2, the accurate ammonia spray equipment for very-short-reach mixing that the utility model provides comprises the female pipe 1 of spray and spray arm 2, the quantity of described spray arm is multiple, described multiple spray arm is connected to that the female pipe of described spray is upper (mutually to be connected side by side and refer to that the ammonia flowing into arbitrary spray arm from female pipe can not flow into the connected mode of another spray arm more mutually side by side, namely the parallel connection in circuit is similar to, see Fig. 1), the female pipe of described spray is positioned at outside gas passage, described spray arm is from described gas passage extension in described gas passage, described gas passage is vertical passageway, the described multiple spray arms being positioned at described gas passage are distributed in same level, the described multiple spray arms being positioned at described gas passage are equipped with nozzle 3, the injection direction of described nozzle is horizontal direction.Spray arm horizontal-jet during work and go out ammonia, the whole cross section of blanketing gas passage, the air-flow of pending gas (waste gas) is from bottom to top vertical with ammonia air-flow, mutual disturbance and mixing, according to actual conditions and adjusting process parameter can be needed, such as ammonia spouting velocity and ammonia spraying amount etc., the mixed effect needed for acquisition, in short distance, (such as 100-300mm) realizes fully mixing of ammonia and pending gas.
Preferably, the set-up mode being positioned at the nozzle on the described spray arm of described gas passage is the arranged on left and right sides being separately positioned on described spray arm, makes the ammonia that the region between adjacent spray arm accepts from left and right both direction simultaneously thus.Because ammonia spreads gradually after nozzle ejection, this correlation mode is conducive to ensureing the even of ammonia.
Preferably, described nozzle is the nozzle of fan-shaped horizontal-jet, and this nozzle is conducive to the distance shortening ammonia blanketing gas passage.
Preferably, the cross section of described gas passage is rectangular, and the described multiple spray arms being positioned at described gas passage are straight tube and are parallel to each other, and its bearing of trend is parallel with a limit of described rectangle.The uniformity being beneficial to air-flow everywhere and mixing with ammonia.
Preferably, the described multiple spray arms being positioned at described gas passage equidistantly distribute, and are beneficial to being uniformly distributed of ammonia, are convenient to spray ammonia and control.
Preferably, on the adjacent spray arm being positioned at described gas passage, the nozzle location of sides adjacent is mutually equidistantly interspersed on the bearing of trend of spray arm, is beneficial to being uniformly distributed of ammonia, is convenient to the control of spray ammonia.
Preferably, spacing between outermost described spray arm and the adjacent wall of described gas passage is the 65-70% of the spacing between adjacent spray arm, and the outer nozzle density of setting being positioned at outermost described spray arm is the 150-160% of side nozzle density of setting.Owing to there is no the correlation of ammonia between outermost spray arm and gas passage sidewall, therefore, need the uniformity improving ammonia by strengthening spray nozzle density, and because ammonia spraying amount also increases accordingly while strengthening spray nozzle density, therefore need the overlay area expanding this side nozzle to offset the increase of ammonia spraying amount, because the air current composition situation near channel side wall and non-edge exist the many reasons such as certain difference, according to the experiment of applicant, adopt above-mentioned parameter can realize good even results.
Preferably, the support for supporting described multiple spray arm end is provided with in described gas passage, to support the spray arm end extending to gas passage opposite side.
Preferably, each described spray arm is equipped with respective separate valve, the installation site of described separate valve on corresponding spray arm is positioned at outside described gas passage.By regulating respective valve, ammonia spraying amount and the spouting velocity of each spray arm can be regulated thus, to be adapted to the spray ammonia demand of respective regions in gas passage, realizing the ammonia spray under point-to-point accurate control.
Preferably, described gas passage is provided with multiple ammonia gas sensor, the distribution mode of sampling/test point in described gas passage of described multiple ammonia gas sensor is be positioned at the same plane above described multiple spray arm, ammonia and the concrete effect with pending gas and vapor permeation thereof in gas passage can be obtained thus in real time, to carry out the valve regulated of relevant spray arm according to these concrete conditions.
Each optimization technique means disclosed in the utility model, unless otherwise indicated and optimization technique means be outside the further restriction of another technological means, all can be combined, form some different technical schemes.
