Hereinafter, referring to Figures 1 and 2, the gas treatment equipment for embodiment that the present invention will be described in detail.Hereinafter, this will be passed through
The gas that the gas treatment equipment of inventive embodiments is handled or purified is referred to as " gas to be processed ".In addition, gas to be processed
Body is the sour gas including at least carbon dioxide, hydrogen sulfide, ammonia etc..
Fig. 1 is the block diagram for conceptually illustrating the gas treatment equipment of the embodiment of the present invention.
The figure of the operation of Fig. 2 multiple Collecting carbonic anhydride devices that have been illustrated.
The gas device to be processed of the embodiment of the present invention acts production sodium bisulfide by it, therefore can also be referred to as sulphur
Change hydrogen sodium manufacturing device.
Referring to Fig.1, the gas treatment equipment of the embodiment of the present invention includes: gas mixer 100, for mixing as purification
Gas to be processed, the ammonia (NH of object3Gas), steam (steam)；Collecting carbonic anhydride device 200, it is to be processed by cooling
The mixed gas that gas, ammonia and steam mix separates carbon dioxide, thus implements carbon dioxide separation；Hydrogen sulfide is caught
Storage 320 traps hydrogen sulfide next life in the gas to be processed by eliminating carbon dioxide from Collecting carbonic anhydride device 200
At sodium bisulfide.
In addition, the gas treatment equipment of the embodiment of the present invention includes: salt decomposer 410, carbon dioxide is come from by receiving
The salt for having trapped carbon dioxide of trap 200 simultaneously changes its gas (gas), thus decomposes the salt；Ammonia scrubbing tower 420, from
Receive to absorb ammonia in the gaseous state product from the salt decomposer 410, thus separates carbon dioxide and ammonia；Ammonia trapping
Device 500, for trapping the product ammonium hydroxide of ammonia scrubbing tower 420.Furthermore it is possible to include from the gas to be processed for eliminating hydrogen sulfide
The ammonia trap of ammonia is trapped in body.
Moreover, the apparatus may include hydrogen cyanide trap 310, the hydrogen cyanide trap 310, will be in carbon dioxide
The gas to be processed that carbon dioxide is eliminated in trap 200 is transferred to before hydrogen sulfide trap 320, from eliminating described two
Hydrogen cyanide is separated in the gas to be processed of carbonoxide, and is passed to hydrogen sulfide trap 320.
To be processed gas and ammonia of the mixing as sour gas in gas mixer 100, at this point, for gas to be processed
The effecting reaction of body and ammonia adds mixed vapour (steam).In the nature of things, if gas to be processed itself contains moisture,
Then without additional mixed vapour.In addition, the amount of ammonia, according to first being removed before removing hydrogen sulfide in gas to be processed
The amount of carbon dioxide and it is different, mixed ammonia amount to meet the carbon dioxide and ammonia to be removed molar ratio be 1: 2 (dioxy
Change carbon: ammonia=1: the 2) condition more than.
It treats processing gas in Collecting carbonic anhydride device 200 and mixed gas that ammonia mixes is cooled down, and
It guides the reaction between carbon dioxide and ammonia in mixed gas to generate ammonium carbonate salts, it is carbonated to be thus separated into packet
Salt (ammonium carbonate salts) and gas to be processed comprising hydrogen sulfide, ammonia, hydrogen cyanide as other substances etc..That is, from
It does not trap hydrogen sulfide, ammonia, hydrogen cyanide in gas to be processed as much as possible, and traps carbon dioxide only selectively to be divided
From.
In this way, in Collecting carbonic anhydride device 200 when cooling mixed gas, in embodiment so that Collecting carbonic anhydride device
The mode of 200 60 DEG C of following temperature of holding is handled, and is more preferably handled in a manner of keeping 50 DEG C of following temperature.This is
Because reaction occurs at 60 DEG C of temperature below between carbon dioxide and ammonia, and generates ammonium carbonate salts.Moreover, because such as
200 supercooling of fruit Collecting carbonic anhydride device, then as other gas (sulfiding gas or ammonia other than the carbon dioxide of target component
Gas) it is possible to condensation together, cause to be separated and removed together.
Moreover, in embodiment, it is cold using using when Collecting carbonic anhydride device 200 is cooled to 60 DEG C of following temperature
But the temperature of Collecting carbonic anhydride device 200 is adjusted to 60 DEG C by the indirect type of cooling of water.
As noted earlier, in an embodiment of the present invention, to be processed to the conduct inside Collecting carbonic anhydride device 200 to supplying
The mixed gas of gas is cooled down with the indirect type of cooling, without the use of direct cooling mode.This is because if to dioxy
Change and supply cooling water inside carbon capture device 200 so that mixed gas and cooling water directly contact to be cooled down, then due in addition to
The dissolution of gas (sulphur gas or ammonia) other than carbon dioxide and the effect for causing carbon dioxide condensing in salt or being separated with salt
Rate reduces, and needs to implement to handle the process of the generation solution of by-product, therefore the type of cooling is more effective indirectly.
After generating ammonium carbonate salts in Collecting carbonic anhydride device 200, the gas to be processed other than ammonium carbonate salts (contains
Hydrogen sulfide, ammonia, hydrogen cyanide) it is moved to subsequent processing device i.e. hydrogen cyanide trap 310 or hydrogen sulfide trap 320.
In addition, in Collecting carbonic anhydride device 200, will not move and the ammonium carbonate salts that remain inside it carry out dissolution or
Fusing.Ammonium carbonate salts have characteristic that is soluble by moisture or heat and decomposing.Therefore, in embodiment, using by moisture
The steam (steam) for including with heat dissolves ammonium carbonate salts, and by its pulp.
Salt decomposer 410 is heated by the slurry ammonium carbonate salts to the product as Collecting carbonic anhydride device 200,
It is vaporized and decomposes.That is, by heating to ammonium carbonate salts, being decomposed into gas shape in salt decomposer 410
State.The salt decomposer of embodiment makes slurry carbonic acid by the heat exchange action between 90 DEG C or more of steam (steam) and ammonium carbonate
Ammonium vaporization (vaporization) or gasification (gasification) are simultaneously decomposed.At this point, the product gas in salt decomposer 410
In body, it is possible to include that carbon dioxide and failing is moved to 200 outside of Collecting carbonic anhydride device and remains in ammonium carbonate
A part of ammonia.Therefore, ammonium carbonate salts by the heat resolve in salt decomposer 410 be carbon dioxide gas, ammonia and
Moisture.
Ammonia scrubbing tower 420 is by being absorbed in the ammonia in carbon dioxide and ammonia from salt decomposer 410
In the clean water separately supplied, carbon dioxide and ammonia are separated.Ammonia is absorbed in clean water, then the clean water becomes ammonia
Water, and so with the carbon dioxide that ammonia separates by being expelled to outside on the upside of ammonia scrubbing tower 420.
In the ammonia scrubbing tower 420 of embodiment, water is used as clean water, however, not limited to this, also can be used and include
Energy simple absorption simultaneously removes the clean water for being included in other solution of the ammonia in gas gas.
In ammonia trap 500, clean water and ammonia are separated by heating ammonium hydroxide, the institute in ammonia trap 500
The ammonia of generation supplies after being recovered to gas mixer, and recycles as the gas with gas mixing to be processed.
In this way, the gas to be processed for removing ammonium carbonate salts (contains during separating carbon dioxide, ammonia from ammonium carbonate
Hydrogen sulfide, ammonia, hydrogen cyanide) be moved to subsequent processing device, that is, it is moved to hydrogen cyanide trap 310 or hydrogen sulfide trap
320。
In hydrogen cyanide trap 310, hydrogen cyanide is trapped from Collecting carbonic anhydride device (200) gas to be processed,
And sulphur (S) is launched to hydrogen cyanide trap 310, thiocyanic acid is generated by making the hydrogen cyanide and sulphur (S) generate reaction
Ammonium (NH4SCN).That is, solid ammonium thiocyanate (NH4SCN hydrogen cyanide) is trapped, not aitiogenic vulcanization is thus separated
Hydrogen and hydrogen cyanide.
Ammonium thiocyanate (the NH of hydrogen cyanide is trapped4SCN it) fixes or remains in hydrogen cyanide trap 310, and hydrogen sulfide
The hydrogen sulfide trap 320 for carrying out subsequent handling is moved to ammonia.
On the other hand, if the hydrogen cyanide contained in gas to be processed be it is micro, will not influence as production object vulcanization
The quality of hydrogen sodium then can be omitted the trapping step of hydrogen cyanide.
So that hydrogen sulfide is become sodium bisulfide by reaction in hydrogen sulfide trap 320, thus separate hydrogen sulfide and ammonia,
Sodium bisulfide is generated in this process.For this purpose, launching sodium hydroxide (NaOH) solution in hydrogen sulfide trap 320, pass through sulphur
The reaction changed between hydrogen and sodium hydroxide manufactures sodium bisulfide aqueous solution, thus separates ammonia and hydrogen sulfide.That is, in movement
Into the gas to be processed of hydrogen sulfide trap 320, hydrogen sulfide is reacted with the sodium hydroxide generation launched generates sodium bisulfide,
And ammonia will not generate reaction with sodium hydroxide, therefore keep ammonia state, thus separate hydrogen sulfide and ammonia.Moreover, vulcanization
Hydrogen sodium is discharged from hydrogen sulfide trap 320, and ammonia resupplies after being discharged from hydrogen sulfide trap 320 to gas mixer, or
It is captured after supply to ammonia trap, is then supplied to ammonia scrubbing tower 420 and is converted into ammonium hydroxide.Ammonium hydroxide is according to concentration and product
Matter is used in place appropriate, can also be sold by purification run separately with ammonium hydroxide.
The sodium bisulfide generated during the trapping of the hydrogen sulfide of hydrogen sulfide trap 320 can be used in the work of many industries
Sequence, for example, being used in the water treatment agent or coating process of removal heavy metal in waste water.In addition, raw in hydrogen sulfide trap 320
At sodium bisulfide aqueous solution concentration, according to the vulcanization hydrogen amount that includes in gas to be processed and the amount of sodium hydroxide launched
Variation and it is different.It is therefore preferable that adjusting its concentration according to the usage of sodium bisulfide.
Gas treatment equipment according to the present invention may include multiple Collecting carbonic anhydride device 200a, 200b, 200c.In addition,
As noted earlier, successively implement to catch by cooling gas to be processed to manufacture in each Collecting carbonic anhydride device 200a, 200b, 200c
Collect the process of the ammonium carbonate salts of carbon dioxide and melts the two processes of the process of ammonium carbonate salts.That is, at one two
Successively implement in carbonoxide trap: by cooling mixed gas come the step of generating ammonium carbonate salts；Gas to be processed is discharged
Step, the gas to be processed include the hydrogen sulfide and ammonia with condensed water and carbon dioxide separation generated in cooling step；
The step of melting ammonium carbonate salts；The step of ammonium carbonate salts of fusing are discharged.In addition, in embodiment, being launched by mixed gas
To before Collecting carbonic anhydride device, Collecting carbonic anhydride device is cooled to the temperature for easily generating salt in advance, which is referred to as
To prepare salt generation step.In addition, mixed gas by being thrown to by the step of generating ammonium carbonate in preparing salt generation step
Cooling in advance Collecting carbonic anhydride device is completed, which is referred to as salt generation step.That is, rearranging one
If process processing step in a Collecting carbonic anhydride device, then successively implement " salt generation step-in Collecting carbonic anhydride device
Step-preparation salt generation step is discharged in condensed water and gas to be processed discharge step-ammonium carbonate salts fusing step-ammonium carbonate salts ",
And repeated multiple times implementation cyclic process.
At this point, making multiple Collecting carbonic anhydride devices about multiple Collecting carbonic anhydride device 200a, 200b, 200c are operated
Each Collecting carbonic anhydride device in 200a, 200b, 200c implements different step, thus in each step in multiple titanium dioxides
Alternately implement in carbon capture device 200a, 200b, 200c.In other words, multiple by making during purifying gas to be processed
Collecting carbonic anhydride device 200a, 200b, 200c can implement respectively the process of different step in the same time, make it possible to more
Substantially alternately staggeredly implement salt generation step and salt dissolving step in a Collecting carbonic anhydride device 200a, 200b, 200c.
For example, in multiple Collecting carbonic anhydride device 200a, 200b, 200c alternately to implement salt generation step and salt is molten
Solve step.In other words, when generating ammonium carbonate salts (salt generation step) in a Collecting carbonic anhydride device, in other dioxies
Change carbon capture device in implement be not salt generation step other steps, such as dissolution ammonium carbonate salts the step of (salt dissolving step).
Again in other words, some Collecting carbonic anhydride device in multiple Collecting carbonic anhydride device 200a, 200b, 200c
It is middle that the gas to be processed for eliminating carbon dioxide is transferred to subsequent step, in the step of melting ammonium carbonate salts, located by making
Reason object mixed gas is flowed into inside other Collecting carbonic anhydride devices and is cooled down, and thus generates ammonium carbonate salts.Namely
It says, during melting ammonium carbonate salts generated in some Collecting carbonic anhydride device, in other Collecting carbonic anhydride devices
Middle generation ammonium carbonate.For this purpose, the mixed gas mixed in gas mixer 100 replaces or in turn catches to multiple carbon dioxide
Storage 200a, 200b, 200c supply mixed gas are simultaneously handled.That is, being mixed with the mixed gas of gas to be processed
It continuously successively or is alternately supply to multiple Collecting carbonic anhydride device 200a, 200b, 200c, therefore can continuously implement to be processed
The cleaning procedure of gas.Therefore, the effect of the purge amount and sodium bisulfide yield that improve gas to be processed is generated.
Hereinafter, referring to FIG. 1 and FIG. 2, for the operation of multiple Collecting carbonic anhydride devices of the embodiment of the present invention, enumerating more
The example of body is illustrated.Has the case where 3 Collecting carbonic anhydride devices here, illustrating.In addition, for purposes of illustration only,
