Abstract

The utility model discloses a caustic soda evaporation process vacuum system which comprises a pipe bundle condenser, a vacuum pump, a triple effect evaporator and a recycling water tank, wherein an uncondensed gas outlet is formed in the upper side of the pipe bundle condenser; a condensed water outlet is formed in the lower side of the pipe bundle condenser; a secondary evaporation steam inlet is formed in the upper side of the middle of the pipe bundle condenser. The system is characterized in that the uncondensed gas outlet is connected with the vacuum pump; the condensed water outlet is connected with the recycling water tank; the triple effect evaporator is connected with the secondary evaporation steam inlet. By adopting the system, not only is the equipment repairing expense reduced, but also the energy is saved, the emission is reduced, and the economic benefits are increased.

Description

A kind of evaporation process of caustic soda vacuum system
Technical field
The utility model relates to a kind of evaporation process of caustic soda vacuum system.
Background technology
What tradition evaporation process of caustic soda vacuum system adopted is that barometric condenser adds vacuum pump system.Recirculated water enters barometric condenser by top, and with the secondary steam counter current contact from triple-effect evaporator, noncondensable gas is taken away by vacuum pump, and the recirculated water of carrying secondary steam water of condensation secretly recycles.There is following shortcoming:
1, secondary steam water of condensation enters circulating water system, cannot recycle;
2,, because the secondary steam water of condensation of carrying secretly contains alkali, so recirculated water needs regular discharge, timing supplements fresh water;
3, circulating water regiment commander alkali, the easy fouling of equipment.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of evaporation process of caustic soda vacuum system.
The technical solution of the utility model is:
A kind of evaporation process of caustic soda vacuum system, comprise pipe bundle condenser, vacuum pump, triple-effect evaporator, recovery tank, the upside of described pipe bundle condenser is provided with noncondensable gas outlet, downside is respectively provided with a condensation-water drain, the upside in mid-way is provided with the import of evaporation secondary steam, it is characterized in that, described noncondensable gas outlet is connected with vacuum pump, described condensation-water drain is connected with recovery tank, and described triple-effect evaporator is connected with the import of evaporation secondary steam.
The flow process of technique of the present utility model:
Recirculated water enters surface condenser, and with triple-effect evaporator secondary steam indirect heat exchange, the condensed water of condensation of secondary steam flows into recycle-water groove and recycles, and noncondensable gas is taken away by vacuum pump, after recirculated water heat exchange, recycles.
The utlity model has following advantage:
1, recovered steam water of condensation and contained caustic soda thereof;
2, recirculated water is not carried secondary steam water of condensation secretly, thereby avoids recirculated water by alkali pollution, real actual zero release.Also reduced in a large number moisturizing simultaneously;
3, recirculated water is not with alkali, has reduced equipment scaling, has reduced maintenance of equipment expense.
Brief description of the drawings
Fig. 1 is system schematic of the present utility model;
Fig. 2 is pipe bundle condenser structural representation of the present utility model;
In figure: 1, pipe bundle condenser, 2, noncondensable gas outlet, 3, secondary steam import,
4, circulating water outlet, 5, circulating water intake, 6, condensation-water drain.
Embodiment
As shown in attached Fig. 1 and 2, a kind of evaporation process of caustic soda vacuum system of the present utility model, comprise pipe bundle condenser, vacuum pump, triple-effect evaporator, recovery tank, the upside of described pipe bundle condenser 1 is provided with noncondensable gas outlet 2, downside is respectively provided with a condensation-water drain 6, the upside in mid-way is provided with evaporation secondary steam import 3, it is characterized in that, described noncondensable gas outlet 2 is connected with vacuum pump, described condensation-water drain 6 is connected with recovery tank, and described triple-effect evaporator is connected with evaporation secondary steam import 3.
