Detailed description of the invention
It should be noted that when not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As it is shown in figure 1, a kind of ammonia absorption device, including condenser 1, surge tank 2, first order absorption tank 4, three grades of touries 5 of 3, two grades of touries and tail gas absorber 8; Condenser 1, surge tank 2,3, two grades of touries of first order absorption tank 4, three grades are sequentially connected by gas pipeline between tourie 5 and tail gas absorber 8; Described first order absorption tank 3 and two grades of tourie 4 tank body lateral walls are all enclosed with heat-insulation layer, described first order absorption tank 3 and two grades of tourie 4 tank interior and all have heat sink.
3, two grades of touries 4 of above-mentioned first order absorption tank and three grades of touries 5 are respectively arranged with air inlet and air vent, and air inlet and air vent are respectively positioned on more than tank body liquid level, air inlet pipe inserts tank base respectively, is positioned under liquid level, and the tube wall of the air inlet pipe below liquid level is provided with hole.
It is sequentially arranged with water between above-mentioned first order absorption tank 3 and two grades of touries 4 and rushes pump 7 and water pump 6, water rushes pump 7 one end and is connected with first order absorption tank 3, additionally two ends are connected with the air inlet of two grades of touries 4, water pump 6 respectively, and water pump 6 other end connects the tank bottoms of two grades of touries 4.
Above-mentioned heat sink is coil pipe, is connected with cooling water in coil pipe.
Above-mentioned tail gas absorber 8 is built with water pump and spray equipment, and its air inlet is positioned at bottom tower body, and inlet end is equipped with blower fan.
The first discharging opening 9 and the second discharging opening 10 it is respectively equipped with bottom above-mentioned surge tank 2 and first order absorption tank 3.
Above-mentioned first order absorption tank 3 sidewall is provided with ammonia concn detector and visual liquidometer.
Discharging substantial amounts of ammonia in .gamma.-pyridinecarboxylic acid and nicotinic acid hydrolysis, enter condenser 1, condensed cooling, steam coagulation Cheng Shui by appendix, accumulate in surge tank 2, ammonia then continues to move forward into first order absorption tank 3. The air inlet of first order absorption tank 3 is positioned at more than tank level, and air inlet pipe is deep into tank base, and the air inlet tube wall below liquid level is equipped with pore, and ammonia becomes tiny bubble through pore, is fully absorbed in water, generates ammonia. Being furnished with the coil pipe of cooling in first order absorption tank 3, be connected with cooling water, have heat-insulation layer outside tank body in dish tank, both cooperations make the temperature in tank maintain less than 25 DEG C, to ensure the absorbance of ammonia. Unabsorbed ammonia enters two grades of touries 4 through exhaustor, and the air inlet of exhaustor is positioned at more than two grades of tourie 4 liquid levels. Two grades of touries 4 are identical with the structure of first order absorption tank 3. Pump 7 is rushed equipped with water between first order absorption tank 3 and two touries 4, under the effect of water pump 6, water body in two grades of touries 4 rushes pump 7 through water pump 6 and water and forms a water ring, the ammonia constantly overflowed by first order absorption tank 3 absorbs to two grades of tourie 4 tank liquid, and make to be formed in first order absorption tank 3 negative pressure, the ammonia that hydrolytic decomposition pot is discharged is brought into first order absorption tank 3. The minute quantity ammonia overflowed in two grades of touries 4, enters three grades of touries 5 by exhaustor. Three grades of tourie 5 only air inlet pipe are covered with hole below liquid level, and in tank, water body is room temperature. The ammonia amount overflowed because of two grades of touries 4 is very little, and therefore these ammonias substantially also can fully absorb with this understanding in three grades of touries 5.Three grades of tourie 5 exhaustors access tail gas absorber 8, eliminate the ammonia release risk to air further. In tail gas absorber 8, inlet end is equipped with blower fan, and tower body, built with water pump and spray equipment, makes the continuous Sprayer Circulation of the water body in tower by water pump, absorbs tail gas. The gas entering tail gas absorber 8 mainly has three parts: Part I originates from the gas of three grades of touries 5, and the ammonia wherein contained is extremely small; Part II originates from the remaining ammonia of workshop bleacher, owing to still having a small amount of ammonia to be dissolved in feed liquid in hydrolytic decomposition pot, enters in bleacher and also can discharge further, and it will directly be brought into absorption tower 8; Part III is the hydrochloric acid of volatilization in workshop and in crystallizer. This three part through spray-absorption, reaches acid-base neutralization in tail gas absorber 8, forms salt ammonium chloride, and environment is harmless. When the ammonia concn of first order absorption tank 3 reaches after more than 25%, namely reach sale standard, can notify that specialty enterprise visits recovery ammonia. After the ammonia water emptying of first order absorption tank 3, weak ammonia in two grades of touries 4 can be proceeded to first order absorption tank 3, continue to absorb ammonia. After water body in two grades of touries 4 proceeds to first order absorption tank 3, the water body of three grades of touries 5 will be transferred into two grades of touries 4. After water body in three grades of touries 5 proceeds to two grades of absorption 4 tanks, tap water will be used directly to supplement three grades of tourie 5 water bodys.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
