Description
Technical Field
The utility model belongs to the technical field of the white dehumidification of environmental protection trade exhaust steam, in particular to white device of environmental protection condensation dehumidification suitable for blast furnace towards sediment, wet flue gas desulfurization system. By the correct implementation of the device, the moisture content of the exhausted steam can be effectively reduced, and the purposes of dehumidifying and whitening can be achieved.
Background
At present, the blast furnace slag flushing in the domestic iron and steel industry mainly adopts a slag flushing form, and a large amount of saturated dead steam is generated in the slag flushing process. Because blast furnace slag flushing steam contains a large amount of emissions such as sulfate ions, chloride ions, slag wool and the like, equipment such as a cast house shed, a traveling crane in front of the furnace, a slag discharging stranding cage and the like is corroded, the operation sight of each production post in front of the furnace is influenced, and potential safety hazards are caused. Meanwhile, as the exhaust steam has higher emission temperature (80-90 ℃) and is in a saturated state, white smoke plume can be generated in the process that the exhaust steam is directly discharged into the atmosphere through a chimney at the top of the granulating tower, the environment-friendly requirement that the exhaust steam emission moisture content of blast furnace slag flushing water in the steel industry is reduced by more than or equal to 50% is difficult to meet, and water resource waste is caused.
According to statistics of relevant data, the outlet of most of the wet flue gas desulfurization systems in China is low-temperature saturated wet flue gas at the temperature of 50-55 ℃. When the low-temperature saturated wet flue gas is directly discharged to the atmospheric environment through a chimney, white smoke plume can be generated, a chimney rain phenomenon can be formed around the chimney, and the corrosion is caused to production plant facilities. The reason for this phenomenon is mainly two-fold, on one hand, the liquid drops mixed in the wet flue gas are carried out directly from the chimney opening, and on the other hand, the saturated flue gas is condensed into small liquid drops at the chimney outlet for the second time.
Aiming at the problems, the mode of setting heat exchanger equipment for heat exchange and condensation or directly heating to improve the exhaust temperature of the smoke is generally adopted in China to treat the white smoke plume. The two modes can achieve the whitening effect, but the treatment system is relatively complex, the problem of occupied land in a factory is difficult to solve, the initial investment of the project is relatively large, the system resistance and the energy consumption are relatively large, and the operation cost is relatively high.
