The specific embodiment
The utility model provides a kind of ammonia retracting device, comprising:
The fluid-tight voltage-stablizer that is communicated with atmosphere;
The absorption surge tank that links to each other with fluid-tight voltage-stablizer gas phase;
Inlet and the gas-liquid dissolving tank that all links to each other of outlet with described absorption surge tank; And
With the circulating pump of the solution in the described absorption surge tank to described gas-liquid dissolving tank or the conveying of finished fluid pipe;
The inlet of described gas-liquid dissolving tank and described absorption surge tank are connected to, and the inlet of described gas-liquid dissolving tank links to each other with described absorption surge tank by described circulating pump;
On the described gas-liquid dissolving tank air admission hole is arranged, be communicated with air inlet pipe; Described absorption surge tank is communicated with liquid supplementation pipe; After described circulating pump was carried the final mean annual increment solution of some to the finished fluid pipe, lysate entered the absorption surge tank through described liquid supplementation pipe.
For making content of the present utility model clearer, below specific embodiment is further elaborated.
As shown in Figure 1, need the ammonia (NH that reclaims
3) be delivered to atomize and dissolve air ejector (above-mentioned gas-liquid dissolving tank is equivalent to atomizing dissolving air ejector in the present embodiment), in atomizing dissolving air ejector, the atomizing that ammonia and circulating pump transport absorption liquid fully mix, be dissolved in the atomized liquid, enter and absorb in the surge tank.The solution that absorbs in the surge tank is delivered to atomizing dissolving air ejector through circulating pump again, forms the solution of atomizing once more, and ammonia is absorbed dissolving.Solution concentration (ammonia concn) in absorbing surge tank is when reaching certain value and so forth, and the final mean annual increment solution of formation (ammoniacal liquor) transfers out by circulating pump.
On the other hand, enter absorb in the surge tank except the absorption liquid that atomized, be not dissolved in the gas in the absorption liquid in addition, these gases also have some insoluble gas (as air) except ammonia.Absorb surge tank and also link to each other, make insoluble gas drain into voltage-stablizer with the voltage-stablizer gas phase.These insoluble gas generally not to external world environment pollute, so voltage-stablizer can be communicated with atmosphere, insoluble gas is drained in the atmosphere.
Why needing voltage-stablizer, mainly is required by the principle of this device.Along with ammonia dissolving rapidly in atomizing dissolving air ejector, promptly gas volume reduces rapidly, and the space in the gas-liquid mixed chamber of atomizing dissolving air ejector can form certain negative pressure, thus to around (such as to air admission hole, inlet) form pumping.Simultaneously, above mention, enter the gas that absorbs in the surge tank and also have insoluble gas such as air except ammonia, this part gas is spilled over to the gas phase part that absorbs surge tank from solution, form gas phase and press P1.When solution did not reach ammonia saturation solubility under the design conditions condition in absorbing surge tank, gas phase ammonia partly seldom.Along with getting more and more that gas overflows from solution, gas phase presses P1 to raise gradually.P1 is high more, and the relative saturation solubility of ammonia is big more, and ammonia content is high more in the absorption liquid.If but P1 is too high, must cause the outlet pressure of atomizing dissolving air ejector to increase, the negative pressure that the air admission hole of the dissolving air ejector that causes atomizing forms reduces, and rate of air sucked in required declines to a great extent.And P1 is too low, and the ammonia saturation solubility also can reduce in the absorption surge tank, is unfavorable for the absorption of ammonia.Therefore, control P1 is the key control parameter of this recovery system.
To the control of P1, in the utility model, mainly utilize voltage-stablizer to carry out.Voltage-stablizer in the present embodiment adopts the fluid-tight voltage-stablizer, promptly absorbs surge tank by in voltage stabilizing communicating pipe and the liquid level that is linked in the fluid-tight voltage-stablizer, controls the gas phase that absorbs in the surge tank by the liquid level of fluid-tight voltage-stablizer and presses.
In another embodiment, the ammonia retracting device comprises that also one section absorbs surge tank and atomizing and dissolves gas phase communicating pipe between the air admission hole of air ejector except each equipment of the foregoing description.According to top embodiment, when absorbing the gas phase pressure P1 arrival certain numerical value in the surge tank, can be by in the fluid-tight voltage-stablizer, discharging the gas in absorbing in the surge tank voltage stabilizing communicating pipe.Also can comprise certain ammonia in these gases, the liquid in the fluid-tight voltage-stablizer can play the certain absorption effect to these ammonias.But the main effect of fluid-tight voltage-stablizer is the balance gas phase presses P1, thus use the very little voltage-stabiliser tube of volume, and splendid attire small volume of solution wherein can realize this effect.So enter in the solution of fluid-tight voltage-stablizer through the voltage stabilizing cross over pipe when absorbing the ammonia that gas comprises in the surge tank, and this part solution then is easy to drain in the atmosphere by the blast pipe on the fluid-tight voltage-stablizer when reaching the saturation capacity of ammonia dissolving.
As avoiding this situation, a kind of method can increase the liquid storage volume of fluid-tight voltage-stablizer, promptly under identical liquid level, increases the container diameter of fluid-tight voltage-stablizer, makes more ammonia to dissolve wherein; Second can regularly change the solution in the fluid-tight voltage-stablizer, reach the solution in the fluid-tight voltage-stablizer of certain ammonia degree of dissolution saturation by release, replenish into new solution by liquid supplementation pipe again.Such as when the solution in the fluid-tight voltage-stablizer is identical with the main component of solution in absorbing surge tank, such as being water, can will reaching solution in the fluid-tight voltage-stablizer of certain ammonia degree of dissolution saturation by water pump and be delivered to and absorb surge tank (or directly to finished product ammoniacal liquor outlet output).
Because ammoniacal liquor is slightly alkaline, so solution can use acid solution to absorb ammonia to the solubility of ammonia in the fluid-tight voltage-stablizer in order to increase, at last the ammonium salt solution that produces is transferred out.Recommendation maintains between 4～6 the acid solution pH value in the fluid-tight voltage-stablizer, when the pH value rises to 6, ammonium salt solution is exported, and is mended into fresh acid solution by liquid supplementation pipe, makes liquid level maintain a stable position.According to the solution difference of putting into, this kind mode can generate different ammonium salts, to satisfy different production demands.
For the ammonia of avoiding absorbing in the surge tank drains in the atmosphere by the blast pipe on the fluid-tight voltage-stablizer,, also can carry out gas phase backflow control, as shown in Figure 2 to the ammonia that absorbs in the surge tank except top mode.In concrete the enforcement, the communicating pipe of can (separately or in conjunction with) using the air admission hole gas phase that absorbs surge tank and atomizing dissolving air ejector to link to each other, make another important means that is set to control gas phase pressure P1 of communicating pipe.Because gas phase presses P1 higher, the saturation solubility that absorbs the ammonia of solution in the surge tank is also higher, and partly ammonia level is higher to absorb in the surge tank gas phase simultaneously.Suppose that the air admission hole of atomizing dissolving air ejector and the gas pressure on the former ammonia conveyance conduit are P3, when gas phase presses P1 to be higher than P3, gas in the absorption surge tank is under the effect of pressure reduction, can be by the continuous air inlet position that is circulated back to atomizing dissolving air ejector communicating pipe of this section gas phase, the solution of atomizing can absorb ammonia wherein, also reduce simultaneously the gas phase that absorbs in the surge tank and pressed P1, guaranteed the rate of air sucked in required of atomizing dissolving air ejector.
Fig. 3 has showed concrete framework map embodiment illustrated in fig. 2.Among Fig. 3, absorb surge tank 101 and link to each other with fluid-tight voltage-stablizer 105 gas phases by voltage stabilizing communicating pipe, add 103 (specific descriptions are seen below) by circulating pump 104 with atomizing dissolving air ejector 102 and be connected, there is valve V2 the centre, is used to adjust the solution internal circulating load.Two factors of the main consideration of the size of internal circulating load, the one, the size that forms negative pressure in the air ejector is dissolved in atomizing, and the 2nd, the fogging degree of absorption liquid in the air ejector is dissolved in atomizing.Matching used with circulating pump 104 is the pump pressure table P2 on next door.Reach or near the finished product ammoniacal liquor of saturation solubility, being recycled pump 104 by valve V3 transfers out, do not reach or near the ammonia spirit of saturation solubility by valve V2, in the carrier pipe of ammonia, be recycled the air admission hole that pump is sent into atomizing dissolving air ejector once more.
In the embodiment that Fig. 3 shows, solution in the fluid-tight voltage-stablizer is communicated with identical lysate source with solution in absorbing surge tank, the main component that is lysate is identical, respectively by valve V5 and V6 control in the fluid-tight voltage-stablizer and absorb complement lysis liquid in the surge tank.Because the main effect of fluid-tight voltage-stablizer is an equalizing pressure,, in the time of also promptly by valve V7 output solution, use the size of V5 switch to keep liquid level so valve V5 will make that the liquid level of solution will keep basicly stable in the fluid-tight voltage-stablizer.Owing to use homolysis liquid source, sneak into the absorption surge tank from the lysate (generally using water pump) of valve V7 output through valve V4, wait for that the circulating pump force feed is to atomizing dissolving air ejector.Also can be directly with the inlet that being pumped into atomizing dissolving air ejector (be the tie point between V7 and the V4 among Fig. 3, move to circulating pump the right from the circulating pump left side).Above output and make-up solution can regularly be carried out, and also can judge whether according to the acid-base value tester (pH value test value) before the valve V7 near saturated dissolving, and whether need the fluid infusion that circulates.
If the solution in the fluid-tight voltage-stablizer 105 is communicated with different lysate sources with solution in absorbing surge tank 101, such as using acid solution in the fluid-tight voltage-stablizer, absorb in the surge tank and make water, then when the pH value test value of V7 top shows near neutrality (such as being 6, keep the absorption that the weak acid performance better guarantees ammonia), solution in the fluid-tight voltage-stablizer can be transported to the ammonium salt receiving system by V7, and by the V5 fluid infusion.
When the value of P1＞P3, Open valve V1 makes the gas gas phase that absorbs in the surge tank 101 be back to the air admission hole of atomizing dissolving air ejector.Can dwindle the volume of fluid-tight voltage-stablizer like this, save the number and the energy consumption (need change into potential energy) of water pump, and be that few ammonia of trying one's best drains into atmosphere by the fluid-tight voltage-stablizer, reduce atmosphere pollution.
Atomizing dissolving air ejector among above-mentioned all embodiment can be realized with ejector.Utilization is to the atomizing of solution, thereby can impel solution and ammonia more large-arealy to contact to cause the solution can more high efficiency absorption ammonia.Through the supercharging of circulating pump, a part of circulation fluid atomizes through spurt hole in the atomizing air ejector.In order to increase the GAS ABSORPTION effect of ejector, will the nozzle of ejector be improved in the present embodiment.In A-A cross section shown in Figure 3, be blast tube structure shown in Figure 4.
The nozzle of ejector has multilayer hydrojet layer, and every layer of described hydrojet layer has many sparge pipes, and every described sparge pipe leads to a spray hole.The cross section of Fig. 4 is certain a layer of hydrojet layer, and three sparge pipes are arranged on this layer, connects three spray holes respectively, and the layout angle BOC of spray hole is 90 degree, and OD divides angle BOC equally, in B, D, the perforate of C place.The central axis of air inlet position air inlet pipe and D hole central axis (promptly parallel) in same plane.Opening diameter, quantity depend on size, the solubility of gas to dissolving of inlet hydraulic and air inflow.Such as working as dissolving to liking ammonia (NH
3), circulation absorbs water yield 12.5m
3During/h, opening diameter is 3mm, totally 10 layers, and 30 holes.Through the supercharging of circulating pump and arranging of spray hole, can make the solution atomization better effects if of ejection, more can promote the dissolving of ammonia.
The atomizing dissolving air ejector of said structure can be realized with ejector, only needs traditional ejector is carried out the improvement of above-mentioned spray hole.In order better to form the negative pressure in gas-liquid mixed chamber in the ejector, can use the venturi ejector, promptly in one section Venturi tube of positioned beneath of traditional ejector.
Venturi tube generally is a kind of pipeline that then enlarges gradually that shrinks earlier.Because sectional area changes, flow velocity changes, and according to Bernoulli equation, pressure also changes thereupon.Bernoulli equation is the form of expression of energy conservation law in working fluid, its to the effect that, fluid is in ignoring the flowing of viscosity loss, pressure potential, kinetic energy and geopotential energy sum any 2 on the streamline remain unchanged.When the pipe diameter of flowing liquid process narrowed down suddenly, its flowing velocity can increase, and caused kinetic energy with a square doubly increase.The variation of ignore bit's potential energy then can violent reducing form negative pressure according to its pressure potential of Bernoulli equation.So the pressure differential at Venturi Guan Qianyu trunnion place, the further negative pressure of increase ejector.
Among Fig. 3 102 refers to the gas-liquid mixed chamber of ejector, and 103 spaces of its below then are Venturi tubes, and the caliber part from large to small of only drawing among Fig. 3 is because this part is the major part that Venturi tube increases negative pressure in the ejector.Fig. 5 has showed the overall picture of venturi ejector: the inlet 1021 of ejector is the inlet of atomizing dissolving aspirator, the gas that enters from air admission hole 1023, mix with the solution that enters from inlet 1021 places and atomize, dissolving in gas-liquid mixed chamber 1022 makes that itself produces negative pressure in 1022.The Venturi first half 1031 is because the negative pressure that Venturi effect produces, and more helps entering and the atomizing of spray hole place solution of ammonia.The below of Venturi Lower Half 1032 joins with the ring flange that is connected the pipeline that absorbs surge tank.
