Description
Technical field
The utility model relates to the corollary apparatus of ammonia method desulfurizing system, particularly a kind of ammonia process of desulfurization crystal solution treating apparatus that reduces chloride ion content in the ammonia process of desulfurization solution and improve crystallization effect.
Background technology
The anticorrosion problem of desulphurization system, it is positions such as desulfurizing tower, flue, chimney that former people pay close attention to many, but along with the application of ammonia-ammonia sulfate method on sintering flue gas desulfurization, the anticorrosion problem of sulphur ammonium system has become the focus that people pay close attention to.Ammonium sulfate solution at high temperature has stronger corrosivity, generally adopts the 316L stainless steel to make so contact its equipment.But the phenomenon that has also occurred quick corrosion in actual use.The corrosion of the stainless steel heater of 316L is to make due to corrosion resisting property descends owing to heater has caused the local material sensitization in the mill, will control the chloride ion content of ammonium sulfate liquor simultaneously, and chloride ion content is met the requirements.
Removal method to chlorion in the wet desulfurization systems such as existing limestone-gypsum method is to adopt the mode of blowdown, and the sewage of discharge carries out corresponding sewage disposal again.But because ammonia nitrogen also is a kind of water pollutant component, and the value of sulphur ammonium is higher, controls the mode of desulphurization system slurries chloride ion content by the mode of blowdown, can't use in ammonia method desulfurizing system.
Ammonium sulfate solution is circular flow in system, and along with the carrying out of running time, chlorion is constantly accumulated in the solution, and concentration is more and more higher, and is also more and more serious to the corrosion of equipment.In addition, along with the circulation that system does not stop, other salinities (such as ATS (Ammonium thiosulphate)) are also more and more in the crystal system, influence the efficient and the pattern of crystallization.Can adopt blowdown to solve not good this problem aspect two of chlorion accumulation and crystallization in that practical sulphur removal is in service, but blowdown and environmental protection pertinent regulations and standard do not meet, it is very big that processing reaches the discharge standard difficulty.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can satisfy in the reduction system chloride ion content simultaneously and improve the requirement of crystallization, and can finally realize without sewage discharge, can obtain the ammonia process of desulfurization crystal solution treating apparatus of more ammonium sulfate products.
The utility model comprises ammonium sulfate solution storage tank, crystallization apparatus and the product jar that is connected by pipeline, and described crystallization apparatus comprises spray drying tower and cyclone separator, and described ammonium sulfate storage tank is connected by the top of pipeline, delivery pump and described spray drying tower; Described spray drying tower is provided with hot-wind inlet; The bottom of described spray drying tower is connected with cyclone separator by pipeline, and the bottom of this cyclone separator is connected with the product jar.
Be provided with the multilayer pulverizer plate in the described spray drying tower, arrange respectively on each pulverizer plate and establish several atomizers.
In order to obtain good atomization drying effect, and make system architecture more simple, described hot-wind inlet is arranged at the top of spray drying tower, and is connected with air blast with air heater successively by pipeline.Described air heater can be preferably electric heater.
In addition, for guaranteeing low pollution emission, described cyclone separator is connected with a sack cleaner by pipeline.
Regulate for handled easily, each contact or branch road in each pipeline are provided with corresponding stop valve.
The utility model is by being provided with spray drying tower, ammonium sulfate solution is atomized in spray drying tower, and carry out drying evaporation by hot-air and form gas-solid mixture, this mixture carries out gas solid separation via cyclone separator, the solid phase product enters the product storage tank, gas phase emptying after the sack cleaner dedusting.In this process, chloride ion-containing and other influence the ion solution of crystallization and pass through the ammonium salt that spray-dryings finally are converted into solid, and the gas of discharge is steam, environmental sound, so the utility model can be realized zero disposal of pollutants; Simultaneously, the chlorion of too high amount and other ions all obtain removing by this device in the solution, make chlorion weaken the corrosivity of solution container and slow down that other ions that influence sulphur crystalline ammonium effect also obtain removing by the method, sulphur crystalline ammonium effect improves.
Compared with prior art, the utility model changes original traditional mode that the blowdown mode is come the content of chlorion in the improvement system of passing through, mode by the atomization drying heating, dry ammonium sulfate solution, transpiring moisture, obtain the ammonium salt crystal, effectively realize wastewater zero discharge, and crystallization effect improves simultaneously.
