Description
Technical field
The utility model relates to ammonia-process desulfurization technique, particularly a kind for the treatment of apparatus of sulphur crystalline ammonium.
Background technology
Thermal power plant ammonia process is a kind of novel sulfur removal technology, and this technology utilizes ammonia as absorbent, absorbs and the curing sulfur in smoke, produces byproduct ammonium sulfate.Find in the actual motion that sulphur ammonium crystal mass is that dewatering system moves normal key factor.Crystal mass mainly contains two indexs, solid content in the slurries and habit size.
Existing sulphur ammonium dehydration is to form ammonium sulfate solution in absorption system, and ammonium sulfate solution is obtained having the slurries of certain solid content by special process, then slurries are directly sent into centrifuge and remove redundant moisture, obtain moisture content at the finished product sulphur ammonium below 1%.The capital equipment of using in this process has: cyclone, centrifuge, drying bed.Slurry temperature after treatment about 60 ℃, separates if slurries are directly entered centrifuge usually, is unfavorable for dehydration, and crystal size that obtains and quantity are all undesirable.As adopt the method for traditional evaporative crystallization, and not only consuming a large amount of steam and electric power, production efficiency is also lower.
The utility model content
The utility model provides a kind of thermal power plant ammonia process byproduct ammonium sulfate slurries cooling reactor, and it is low to solve existing sulphur ammonium crystal mass, the technical problem that the crystal separation effect is bad, energy consumption is high, production efficiency is low.
The technical scheme that its technical problem that solves the utility model adopts is:
This thermal power plant ammonia process byproduct ammonium sulfate slurries cooling reactor, come the slurries cooling reactor on the water pipe to constitute main body by being connected fresh water (FW), the agitator that stretches into downwards in the slurries is installed in the slurries cooling reactor, the slurries cooling reactor is provided with cooling sandwith layer outward, cooling water inlet and coolant outlet are arranged respectively at the bottom of cooling sandwith layer and top, the cooling water inlet is connected with the fresh water (FW) arm 7 that fresh water (FW) comes water pipe to tell, coolant outlet comes water pipe to be connected through cooling water outlet pipe and fresh water (FW), and cooling water outlet pipe and fresh water (FW) come the junction of water pipe to close on the water inlet of technology water tank.
The thickness of described cooling sandwith layer is 80～120mm.
Described agitator is a low speed jacking-type agitator.
Principle of the present utility model is as follows: desulphurization system needs a certain amount of fresh water (FW) consumption, is supplemented to the technology water tank by pipeline.In the ammonia process of desulfurization, slurry temperature usually about 60 ℃, and in the system fresh water (FW) moisturizing temperature usually about 30 ℃.The utility model utilizes the temperature difference of two media, and the cooling device by the strap clamp layer carries out the heat transmission, thereby reaches the purpose that reduces slurry temperature, improves crystal mass, and then optimizes the disposal ability of follow-up dewatering system.
The beneficial effects of the utility model are as follows: the utility model tells on the waterpipe bypass at fresh water (FW), and through entering the technology water tank again behind the cooling sandwith layer outside the slurries cooling reactor, Total Body Water does not change.The temperature (about 30 ℃) that is used to water is cooled to 40 ~ 50 ℃ with slurries (about 60 ℃), by reducing slurry temperature, has improved the habit size, helps dehydration.Be equipped with the jacking-type agitator of low speed simultaneously in the slurries cooling reactor, can make the cooling of slurries uniform decrease in temperature, thereby sulphur ammonium crystal mass is further enhanced.Because replenishing of fresh water (FW) also is the necessary link of system, and moisturizing all has certain pressure, and the utility model does not additionally increase supplies consumption and energy consumption to system, only increases the slurries cooling reactor and get final product on fresh water (FW) moisturizing incoming flow.
The utility model is simple in structure, easy for installation, need not to increase system energy consumption, significantly improved sulphur ammonium crystal mass, and the crystal that can be widely used in thiamines in the ammonia process of desulfurization is handled.
