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.

Detailed Description
The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments of the present invention when taken in conjunction with the accompanying drawings. Like reference numerals refer to like parts throughout the drawings. The drawings are not intended to be to scale, emphasis instead being placed upon illustrating the principles of the invention.
As shown in fig. 1, the novel condensate water recovery device for sodium sulfide evaporator comprises an evaporator 1, an axial flow pump 2 is arranged at the bottom of the evaporator 1, the top of the evaporator 1 is connected with a steam condensation separation device 9 through an evaporation vacuum pipeline 5, the steam condensation separation device 9 is connected with an injection pump 7 through a circulating water pipeline 6, the injection pump 7 sprays circulating water into a circulating water pool 4, the circulating water pump 3 is connected with the circulating water pool 4, the circulating water in the circulating water pool 4 is provided for the steam condensation separation device 9 through the circulating water pump 3, and the steam condensation separation device 9 is also connected with a condensate water recovery tank 8 through a condensate water pipeline 10.
In this is novel, high temperature steam in the evaporimeter 1 passes through evaporation vacuum pipe 5 and gets into steam condensation separator 9, under the cooling of circulating water, steam condensation separator 9 realizes the steam condensation, and the comdenstion water gets into condensate water recovery tank 8 through condensate water pipeline 10, and circulating water route has been constituteed to jet pump 7, circulating water pond 4, circulating water pump 3 and circulation water course 6, and circulating water circulation gets into steam condensation separator 9, provides the cooling water for steam condensation separator 9.
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.
In the previous description, numerous specific details were set forth in order to provide a thorough understanding of the present invention. The foregoing description is only illustrative of the preferred embodiments of this invention and, therefore, the invention is not limited to the specific details disclosed herein, since the invention can be practiced in many other ways than those specifically described herein.
