Desulfurization waste water prevapourising zero release processing apparatus

The utility model discloses a desulfurization waste water prevapourising zero release processing apparatus, include the denitrification facility, air heater, dust remover and the desulfurizing tower that communicate in proper order by the pipeline, desulfurizing tower intercommunication waste water tank is connected the waste water tank and is set up the evaporimeter, has atomizing nozzle in the evaporimeter, by the waste pipe intercommunication between waste water tank and the evaporimeter, connects the evaporimeter and sets up gas pipeline and moisture pipeline respectively, and on gas pipeline connected the pipeline between denitrification facility and air heater, the moisture pipeline was connected on the pipeline between air heater and dust remover. Compared with the prior art, the utility model discloses an introduce the intensive and desulfurization waste water heat transfer within a definite time of high temperature air current, realized that desulfurization waste water evaporates completely when the discharge evaporimeter, collected once more after the solid particle drying in the waste water, realize the effect of desulfurization waste water zero release.
