Abstract
The utility model discloses an energy saving device capable of reducing the ethyl amine production cost. The energy saving device consists of a dehydration tower, a heat exchanger I, a heat exchanger II and an integration tower and is characterized in that a hot water outlet and a feed liquid inlet are formed in the dehydration tower; a water inlet and a feed liquid outlet are formed in the integration tower; a hot water inlet and a hot water outlet are formed in each of the heat exchanger I and the heat exchanger II; a feed liquid inlet is formed in the top of the heat exchanger I, and a feed liquid outlet is formed in the bottom; and a circular cold water inlet is formed in the top of the heat exchanger II, and a cold water outlet is formed in the bottom. The energy saving device disclosed by the utility model has the beneficial effects that the hot water flowing out from the bottom of the dehydration tower and the feed of the dehydration tower are subjected to heat exchange by two heat exchangers, the feed temperature of the dehydration tower is increased, the use of high-pressure steam of the dehydration tower is reduced, the temperature of the washing water at the bottom of the dehydration tower is reduced, thus the use of circular cold water of the heat exchanger is remarkably reduced, and the production cost is effectively lowered.
Description
Technical field
The utility model relates to chemical production technical field, relates in particular to a kind of energy saver that can reduce the ethylamine production cost.
Background technology
In the ethylamine production process, be 123 ℃ from the temperature of the hot water at the bottom of dehydration tower, need to be cooled to 62 ℃ by circulating water and just can enter integrated tower and mix from the material at the bottom of pure tower, this needs about 10m
3The temperature that the circulating water of/h just can be cooled to be scheduled to, simultaneously, the temperature of dehydration tower feed plate is more than 118 ℃, feeding temperature is lower, the amount of the 2.0MPa high pressure steam that dehydration tower consumes is larger, and not only the recirculated water usage quantity is large in this technical process, also consumes more high pressure steam.
Summary of the invention
The purpose of this utility model is in order to overcome the technical deficiency of the high water consumption of above-mentioned technical process, high consumption vapour, a kind of energy saver that can reduce the ethylamine production cost to be provided.
The utility model is to address the above problem the technical scheme of taking to be: a kind of energy saver that can reduce the ethylamine production cost, formed by dehydration tower, interchanger one, interchanger two, integrated tower, it is characterized in that: described dehydration tower is established hot water outlet and liquor inlet, integrated tower is established water inlet and material liquid outlet, interchanger one, interchanger two are equipped with hot water inlet and outlet, liquor inlet is established at interchanger one top, material liquid outlet is established in the bottom, the circulating water import is established at interchanger two tops, and cooling water outlet is established in the bottom; The hot water outlet of described dehydration tower and interchanger one hot water inlet UNICOM, interchanger one hot water outlet and interchanger two hot water inlet UNICOMs, interchanger two hot water outlets and integrated tower water inlet UNICOM, integrated tower material liquid outlet and interchanger one liquor inlet UNICOM, interchanger one material liquid outlet and dehydration tower liquor inlet UNICOM; The utility model technical process is: from the hot water at the bottom of dehydration tower after hot water outlet enters interchanger one and material-heat-exchanging from integrated tower, after lowering the temperature, interchanger two and circulating water heat exchange enter integrated tower again, enter interchanger one heat exchange by integrated tower material liquid outlet material out through interchanger one liquor inlet, the feed liquid after heat exchange enters dehydration tower through the dehydration tower liquor inlet.
Beneficial effect: by two interchanger are set, heat exchange is carried out in the hot water that goes out with dehydration column bottoms stream and the charging of dehydration tower, both improved the dehydration tower feeding temperature, reduced dehydration tower high pressure steam usage quantity, reduced again the temperature of washing water at the bottom of dehydration tower, the circulating water usage quantity of interchanger is significantly reduced, effectively reduce production cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Accompanying drawing is the utility model schematic diagram.
In figure: 1 dehydration tower, 2 interchanger one, 3 interchanger two, 4 integrated towers, 5 dehydration tower hot water outlets, 6 interchanger one hot water inlets, 7 dehydration tower liquor inlet, 8 interchanger one liquor inlet, 9 interchanger one material liquid outlets, 10 interchanger one hot water outlets, 11 interchanger two hot water inlets, 12 interchanger two circulating water outlets, 13 interchanger two circulating water imports, 14 circulating waters, 15 interchanger two hot water outlets, 16 integrated tower water inlets, 17 integrated tower feed liquids go out
Embodiment
A kind of energy saver that can reduce the ethylamine production cost as shown in the figure, described dehydration tower 1 is established hot water outlet 5 and liquor inlet 7, integrated tower 4 is established water inlet 16 and material liquid outlet 17, interchanger 1, interchanger 23 are equipped with hot water inlet and outlet, liquor inlet 8 is established at interchanger one 2 tops, material liquid outlet 9 is established in the bottom, and circulating water import 13 is established at interchanger 23 tops, and cooling water outlet 12 is established in the bottom; From the hot water at 1 end of dehydration tower after hot water outlet 5 enters interchanger 1 and material-heat-exchanging from integrated tower 4, after lowering the temperature, interchanger 23 and circulating water 14 heat exchange enter integrated tower 4 again, enter interchanger one 2 heat exchange by integrated tower material liquid outlet 17 material out through interchanger one liquor inlet 8, the feed liquid after heat exchange enters dehydration tower 1 through dehydration tower liquor inlet 7.
