Description

Technical Field

[0001] The utility model relates to the field of recovery systems, in particular to a heat recovery system for ethylene carbonate. Background Art

[0002] Heat recovery technology is to recycle the large amount of waste heat discharged to the outside during the operation of the chiller in a certain way as the final heat source or primary heat source for the user. According to the amount of heat recovered by the heat recovery device, heat recovery can be divided into partial heat recovery and full heat recovery. Among them, partial heat recovery can only recover part of the heat discharged by the chiller, and full heat recovery basically recovers all the heat discharged into the environment by the system;

[0003] However, the heat recovery in the current technology cannot fully utilize the heat, so a device is proposed that can fully utilize the reaction heat of the device as material heating, which is economical, energy-saving and emission-reducing. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a heat recovery system for ethylene carbonate, which can fully utilize the reaction heat of the device as material heating, and achieve economic energy saving and emission reduction.

[0005] To solve the above technical problems, according to one aspect of the utility model, more specifically, a heat recovery system for ethylene carbonate includes a steam water separator, the output end of the steam water separator is fixedly connected to various steam use points, the output end of each steam use point is fixedly connected to a high-temperature condensate tank, the output end of the high-temperature condensate tank is fixedly connected to a high-temperature water pump, the output end of the high-temperature water pump is fixedly connected to a storage pipe heating, the output end of the storage pipe heating is fixedly connected to a low-temperature condensate tank, the output end of the low-temperature condensate tank is fixedly connected to a low-temperature water pump, and the output end of the low-temperature water pump is fixedly connected to a reaction circulation heater.

[0006] The beneficial effects of the heat recovery system for ethylene carbonate of the utility model are:

[0007] Steam is purchased from outside units, and after dehydration in the steam water separator, the steam goes to various steam use points. The condensed water after steam heat exchange enters the high-temperature condensate tank, and is pumped into each pipeline and storage pipe by a high-temperature water pump for heating. The low-temperature condensate after heating enters the low-temperature condensate tank, and a part of the low-temperature condensate is pumped to the reaction circulation heater to extract the heat from the reactor to become high-temperature condensate and enter the high-temperature condensate tank, and the other part of the low-temperature condensate is directly thrown to the circulating water plant so that the steam heat in the system can be used multiple times, saving energy and reducing consumption.
