Abstract
The utility model relates to a negative pressure ammonia evaporation system. The ammonia evaporation system comprises an ammonia tank, the ammonia tank is communicated with a reaction tower by a pipeline, the reaction tower is communicated with a negative pressure ammonia evaporation tower, the upper part of the negative pressure ammonia evaporation tower is communicated with a coal gas main pipeline, the lower part of the ammonia evaporation tower is communicated with a tar emptying tank, a water ring vacuum pump is arranged between the negative pressure ammonia evaporation tower and the coal gas main pipeline, and the liquid ring in the water ring vacuum pump is formed by condensing distilled water. As the liquid ring in the water ring vacuum pump is form by condensing distilled water, no impurities are contained, the temperature is also low, no scale is formed, the blocking of the pipeline is avoided, thereby prolonging the service life of the water ring vacuum pump, decreasing the replacing times of the water ring vacuum pump, reducing the time of repair, improving the working effects, and saving the investment on the equipment; and the negative pressure ammonia evaporation system has a simple structure, is convenient to use, and is suitable for coal chemical enterprises.
Description
Technical field
The utility model belongs to coal chemical technology, relates in particular to a kind of negative pressure ammonia steaming system.
Background technology
In the Coal Chemical Industry production process, the ammoniacal liquor water that solid ammonium-salt and volatile ammonium salt or ammonia quantity are little is handled without ammonia still process, causes containing a large amount of ammoniacal liquor in the coking chemical waste water, causes the too high sewage treatment capacity of biochemical sewage basicity to descend.On the other hand, the ammonia in the ammoniacal liquor that solid ammonium-salt and volatile ammonium salt or ammonia quantity are little can not be fully utilized.Generally adopt the negative pressure ammonia steaming system at present, this system comprises and contains ammonia vessel, ammonia vessel is by pipeline and reaction tower UNICOM, reaction tower and negative pressure ammonia still UNICOM, the top of negative pressure ammonia still and coal gas main pipe line UNICOM, bottom and tar emptying groove UNICOM are provided with water ring vacuum pump between negative pressure ammonia still and coal gas main pipe line.This negative pressure ammonia steaming system is that remaining ammoniacal liquor is flashed to ammonia, uses for making ammonia salt operation down.Vacuum produces vacuum tightness by impeller in circulation fluid in the vacuum pump system under the effect of electric motor, reduce the required temperature of ammonia evaporation, recirculated water in the present vacuum pump adopts recirculated water, and the temperature of advancing vacuum pumping hole recirculated water has degree more than 70, and contain plurality of impurities in the recirculated water, meeting of long duration causes vacuum pump the inside fouling, blocking pipe.Thereby vacuum pump is damaged, and frequent replacing vacuum pump not only influences working efficiency, and the cost of equipment is also bigger simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of negative pressure ammonia steaming system is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of negative pressure ammonia steaming system, comprise ammonia vessel, ammonia vessel is by pipeline and reaction tower UNICOM, reaction tower and negative pressure ammonia still UNICOM, the top of negative pressure ammonia still and coal gas main pipe line UNICOM, bottom and tar emptying groove UNICOM are provided with water ring vacuum pump between negative pressure ammonia still and coal gas main pipe line, the pendular ring in the water ring vacuum pump is formed by condensation distilled water.
Above-mentioned a kind of negative pressure ammonia steaming system, the bottom of described negative pressure ammonia still also is provided with interchanger.
Adopt technique scheme, the utility model has following advantage:
Since adopt the pendular ring in the water ring vacuum pump to form by condensation distilled water, inclusion-free, and temperature is also very low, can not form fouling, has avoided the phenomenon of blocking pipe to take place, thereby has prolonged the work-ing life of water ring vacuum pump.Reduce to change the number of times of vacuum pump, thereby reduced the time of maintenance, improved the work effect, saved the infusion of financial resources of equipment.And the utility model is simple in structure, and is easy to use, is fit to coal chemical industry enterprises.
Figure of description
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of negative pressure ammonia steaming system as shown in Figure 1, comprise ammonia vessel 1, ammonia vessel 1 is by pipeline and reaction tower 2 UNICOMs, reaction tower 2 and negative pressure ammonia still 3 UNICOMs, the top of negative pressure ammonia still 3 and coal gas main pipe line 8 UNICOMs, bottom and tar emptying groove 5 UNICOMs, between negative pressure ammonia still 3 and coal gas main pipe line 8, be provided with water ring vacuum pump 6, pendular ring 7 in the water ring vacuum pump 6 is formed by condensation distilled water, the bottom of described negative pressure ammonia still 3 also is provided with interchanger 5, interchanger 5 is chemical enterprise interchanger commonly used, can buy on market.
