Description

Condensate water recovery equipment of sodium sulfide evaporator

Technical Field

The utility model relates to a sodium sulfide production facility, its single effect evaporator condensate recovery who is mainly applied to multi-effect evaporator end effect evaporator and industry enrichment facility.

Background

At present, in order to obtain low-boiling-point evaporation, a mixed mode of cooling circulating water and evaporated secondary steam is mostly adopted to obtain vacuum, the evaporation temperature is 80-155 ℃, all the last-effect evaporator and the single-effect evaporator are provided with a jet pump at a height of more than 10 meters above an evaporation chamber, the evaporation chamber is caused to be in a negative pressure state by adopting a circulating water mode, and the evaporation intensity and the evaporation capacity are increased. However, the above techniques have the following drawbacks: firstly, condensed water in the evaporated liquid enters a circulating water tank, and the condensed water cannot be recovered; secondly, high-temperature condensed water enters a circulating water tank to cool the condensed water, so that secondary working pressure is caused; thirdly, the high-temperature condensed water cannot be recycled, which wastes secondary energy and is easy to cause harm to the environment.

SUMMERY OF THE UTILITY MODEL

To prior art's defect, this is novel provides a sodium sulfide evaporator comdenstion water recovery plant.

The utility model provides a sodium sulfide evaporimeter comdenstion water recovery plant, a serial communication port, including the evaporimeter, the bottom of evaporimeter is provided with the axial-flow pump, the top of evaporimeter links to each other with steam condensation separator through evaporation vacuum pipeline, steam condensation separator passes through circulating water pipe connection jet pump, the jet pump sprays circulating water to the circulating water pond in, circulating water pump is connected with the circulating water pond, provide steam condensation separator with the circulating water in the circulating water pond through circulating water pump, steam condensation separator still links to each other with the condensate water accumulator through condensate water pipeline.

This neotype beneficial effect is: this novel guarantee end effect evaporimeter and single effect evaporimeter negative pressure degree: under the working condition of 0.07MPa-0.09MPa, the separation of secondary steam and circulating condensed water is realized, the condensation of the secondary steam is completed, and the recovery of high-temperature condensed water is realized; the newly added vacuum equipment ensures the negative pressure vacuum degree of the final effect evaporator and the single effect evaporator: 0.07MPa to 0.09 MPa; the heat exchanger is designed according to the amount of secondary steam, and after the new technical scheme is implemented, the condensate water of the last-effect evaporator and the single-effect evaporator is completely recycled and utilized, so that the sewage discharge amount is reduced. The recovery amount of condensed water is t/day, and the improvement realizes energy saving: 1000 tce/day. The water quality of the circulating water tank is effectively improved.
