911 include movable mouth 9111, connecting column 9112, movable loop 9113, compressed spring 9114 and fastening rope 9115, movable loop
To be flexibly connected between 9113 and connecting column 9112, compressed spring 9114 is located at lower end and the activity mouth 9111 of movable loop 9113
Inside upper end outer surface between, and the movable outside for being placed on connecting column 9112 of compressed spring 9114, fastening rope 9115 is solid
The fixed outer surface for being placed on movable loop 9113 is connected between movable loop 9113 and water-absorption fiber 10 by fastening rope 9115
It connects, the first interspersed bracket 93 and the second interspersed bracket 94 are through the inside of water-absorption fiber 10.
When work, sulfuric acid solution is added in the first sulfuric acid solution pond 4 and the second sulfuric acid solution pond 6 in advance in user, and makes
Electric hot plate 5 is heated, and is controlled fluid temperature in the first sulfuric acid solution pond 4 and is opened gas between 100 degree to 120 degree
Pump 85 is supplied, and the gas for being mixed with ammonia enters from air inlet 2, and the gas of air pump 85 flow to interior logical by external tracheae 84
It in tracheae 8, is discharged by inclination outlet nozzle 81, and reaches the first sulfuric acid solution pond 4, lower temperature accelerates the first sulfuric acid solution
The output of vapor, vapor dissolve and absorb ammonia in pond 4, partially fall in the first sulfuric acid solution pond 4 of meeting, by vertical
The effect of outlet nozzle 82 leads to downward air-flow so that flow of water vapor is to the inside of water-absorption fiber 10, while extraneous temperature
Lower air is spent to 10 continued down of water-absorption fiber, accelerates the condensation of vapor, and is dripped back into the second sulfuric acid solution pond 6；
Sulfuric acid in first sulfuric acid solution pond 4 and the second sulfuric acid solution pond 6 reacts with ammonia water to form ammonium sulfate, can be subsequent by water pump 75
It extracts liquid out, and then ammonium sulfate solids is pulled out as Fertilizer application, while the gas purified is discharged from air outlet 3.
In conclusion heated by electric hot plate 5, fluid temperature is controlled in the first sulfuric acid solution pond 4 at 100 degree extremely
It between 120 degree, opens air pump 85 and is supplied, so that the inclination outlet nozzle 81 for being located at 4 top of the first sulfuric acid solution pond will
Outdoor more cold gas is squeezed into, and cold air, which preheats, itself generates vapor, while sulfuric acid solution is generated water by thermal evaporation and steamed
Gas at gas and air inlet 2 higher than outdoor temperature generates vapor to the cold, jointly promotes on the first sulfuric acid solution pond 4
Side generates a large amount of vapor, and the gas for being mixed with ammonia enters from air inlet 2, and a large amount of vapor carries out dissolution suction to ammonia
It receives, forms ammonium hydroxide, therefore have preferable assimilation effect to ammonia；The vapor for absorbing ammonia forms ammonium hydroxide floating, and part is dripped
It falls in the first sulfuric acid solution pond 4, continues the effect after flowing by vertical outlet nozzle 82, generate downward air-flow so that water
Flow of vapor is to the inside of water-absorption fiber 10, and the belt strip 101 positioned at 10 lower end outer surface of water-absorption fiber increases and vapor
Contact area, preferable to absorb, while the drippage of the band-like liquid for being conducive to guidance water suction is presented, water barrier 102 prevents from inhaling
The liquid of water it is excessive accumulate in a lower height of side of water-absorption fiber 10, and reduce drippage efficiency, while ambient temperature is lower
Air the condensation of vapor is accelerated to 10 continued down of water-absorption fiber, and drip back into the second sulfuric acid solution pond 6, ammonium hydroxide with
Sulfuric acid reaction in first sulfuric acid solution pond 4 and the second sulfuric acid solution pond 6 forms solid-state ammonium sulfate, can work as subsequent recovery
Make Fertilizer application；Inclination outlet nozzle 81 tilts downwards the outer gas of discharge chamber, while vertical outlet nozzle 82 sprays downwards gas,
So that the inside of shell 1 generates the air-flow for tilting down flowing to 3 direction of air outlet, so that the gas in house exists
After air inlet 2, it can be smoothly discharged at air outlet 3 after processed, that is, reach the effect that ammonia absorbs processing
Fruit, while also having ensured the smooth outflow of gas.
The present invention also provides the application methods that a kind of power engineering is protected with cable connection:
A, sulfuric acid solution is added in the first sulfuric acid solution pond 4 and the second sulfuric acid solution pond 6 in advance, and carries out electric hot plate 5
It heats, fluid temperature is between 100 degree to 120 degree in the first sulfuric acid solution pond 4 of control, and controls the first sulfuric acid solution
Sulfate liquid concentration is opened air pump 85 and is supplied between 18%-25% in pond 4；
B, the gas for being mixed with ammonia enters from air inlet 2, and the gas of air pump 85 flow to interior ventilation by external tracheae 84
It in pipe 8, is discharged by inclination outlet nozzle 81, and reaches the first sulfuric acid solution pond 4, lower temperature accelerates the first sulfuric acid solution pond
The output of vapor, vapor dissolve and absorb ammonia in 4, partially fall in the first sulfuric acid solution pond 4 of meeting；
C, by the effect of vertical outlet nozzle 82, lead to downward air-flow so that the flow of water vapor in above-mentioned b is extremely inhaled
The inside of water cellulose 10, while the lower air of ambient temperature holds 10 continuous coolings to water-absorption fiber 10, accelerates the condensation of vapor,
And it drips back into the second sulfuric acid solution pond 6；
D, the sulfuric acid in the first sulfuric acid solution pond 4 and the second sulfuric acid solution pond 6 reacts with ammonia water to form ammonium sulfate solids, borrows
By water pump 75 can subsequent extraction liquid, and then the gas that ammonium sulfate solids are pulled out as Fertilizer application, while being purified is from outlet air
It is discharged at mouth 3.
