Abstract
One changes increasing rich solution and enters tower preheater, comprise condensate pump, condensation waterline, heat exchanger, preheater, solvent regeneration tower, described condensation waterline is divided into two, wherein one is equipped with condensate pump, another is connected with preheater by valve, condensation waterline arrives heat exchanger through preheater tube, and preheater is connected with solvent regeneration tower by condensation waterline; Advantage is: the temperature that both can improve charging, reduces the waste of thermal source; The temperature of condensate water can be reduced again, avoid the water attack of pipeline.
Description
Technical field
The utility model relates to a kind of preheater, particularly relate to one change increase rich solution enter tower preheater.
Background technology
The rich solvent that 203 desulfurization units and hydrogenation come enters into 208-D-301 tank, and after 208-E-301 and 208-E-302 heat exchange, enter 208-C-301, the design temperature of tower charging is 98 DEG C, and present practical operation temperature is 88 DEG C, does not reach design load.
After the condensate water that 208 unit solvent reclamations and sewage stripping system produce enters 208-D-109, through 208-P-107 transport pump to pipe network, because temperature is higher, often occur water hammer, the after-heat of condensate water is not utilized effectively.Lean solvent after regeneration enters into 208-D-303 after extracting out at the bottom of 208-C-301 tower after 208-A-302 and 208-E-305A/B cooling, and it is smaller that 208-E-305AB recirculated cooling water often closes, and the cooling load of 208-E-305A/B can not get effective utilization.
Utility model content
For avoiding the deficiencies in the prior art, the utility model provide one change increase rich solution enter tower preheater.
The technical solution of the utility model is: one changes increasing rich solution and enters tower preheater, comprise condensate pump, condensation waterline, heat exchanger, preheater, solvent regeneration tower, described condensation waterline is divided into two, wherein one is equipped with condensate pump, another is connected with preheater by valve, condensation waterline arrives heat exchanger through preheater tube, and preheater is connected with solvent regeneration tower by condensation waterline.
The beneficial effects of the utility model are: the temperature that both can improve charging, reduce the waste of thermal source; The temperature of condensate water can be reduced again, avoid the water attack of pipeline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein 1 is condensate pump, and 2 is valve, and 3 is preheater tube, and 4 is preheater, and 5 is solvent regeneration tower, and 6 is heat exchanger, and 7 is condensation waterline.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
One changes increasing rich solution and enters tower preheater, comprise condensate pump 1, condensation waterline 7, heat exchanger 6, preheater 4, solvent regeneration tower 5, described condensation waterline 7 is divided into two, wherein one is equipped with condensate pump 1, another is connected with preheater 4 by valve 2, condensation waterline 7 arrives heat exchanger 6 through preheater tube 3, and preheater 4 is connected with solvent regeneration tower 5 by condensation waterline 7.
Claims (1)
1. one kind change increase rich solution enter tower preheater, comprise condensate pump, condensation waterline, heat exchanger, preheater, solvent regeneration tower, it is characterized in that: described condensation waterline is divided into two, wherein one is equipped with condensate pump, another is connected with preheater by valve, condensation waterline arrives heat exchanger through preheater tube, and preheater is connected with solvent regeneration tower by condensation waterline.
