Abstract
The utility model relates to a heat exchange device of a spray tower. The heat exchange device comprises the spray tower (1), a primary exchanger (2), a spray pump (3) and a heat exchanger (4). The heat exchange device is characterized in that an air outlet of the spray tower (1) is connected with a secondary exchanger (6), the secondary exchanger and a refrigerator (7) form a loop, and a refrigerated water inlet of the secondary exchanger is provided with an automatic regulating valve (8). After the secondary exchanger is added, an original heat exchanger only needs refrigerated water for refrigeration; and the work mode of the refrigerator is controlled by the automatic regulating valve, so that the energy-saving effect is achieved.
Description
Technical field
The utility model relates to a kind of spray column heat-exchange device, is mainly used in to separate the steam that has in the hot blast.
Background technology
General hot blast of from the drying tower of slices of caprone, discharging has steam, and these hot blasts that have steam are separated out steam through the spray column heat-exchange device, simultaneously the temperature of hot blast are reduced to the temperature of technological requirement.The spray column heat-exchange device chilled water that adopts refrigerator to provide was lowered the temperature to hot blast in the past, and the operating power of refrigerator can reach 1,000,000 kilocalories, used this refrigerator very power consumption source that lowers the temperature for a long time.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of spray column heat-exchange device is provided, and under the lower weather of temperature, can directly close refrigerator, saves energy consumption.
The purpose of the utility model is achieved in that a kind of spray column heat-exchange device; It comprises spray column, one-level interchanger, spray pump and heat exchanger; The air outlet of said one-level interchanger links to each other with the air inlet of spray column, and the delivery port of said spray column links to each other with the water inlet of spray pump, and the delivery port of said spray pump links to each other with the water inlet of heat exchanger; The delivery port of said heat exchanger links to each other with nozzle in the spray column; The air outlet of said spray column is connected with the secondary interchanger, and said secondary interchanger and a refrigerator form the loop, is provided with automatic regulating valve in the chilled water import department of secondary interchanger.
Said automatic regulating valve is used to control the switch of refrigerator.
Be provided with the cooling water import and export with heat exchanger on the said one-level interchanger, adopt cooling water as refrigerant.
Compared with prior art, the invention has the beneficial effects as follows:
The utility model only needs to cool off with cooling water through original heat exchanger after increasing the secondary interchanger; When environment temperature is low (as in winter; Spring and autumn evening) cooling water temperature is below 12 ℃; Just can the refrigerator of 1,000,000 kilocalories cut out, save the energy fully without chilled water.If cooling water temperature is higher than 12 ℃, then can open refrigerator automatically, the mode of operation of controlling refrigerator through automatic regulating valve is to reach energy-conservation effect.

The specific embodiment
Referring to Fig. 1; The utility model relates to a kind of spray column heat-exchange device, and it comprises spray column 1, one-level interchanger 2, spray pump 3 and heat exchanger 4, and the air outlet of said one-level interchanger 2 links to each other with the air inlet of spray column 1; The delivery port of said spray column 1 links to each other with the water inlet of spray pump 3; The delivery port of said spray pump 3 links to each other with the water inlet of heat exchanger 4, and the delivery port of said heat exchanger 4 links to each other with spray column 1 interior nozzle 5, and the air outlet of said spray column 1 is connected with secondary interchanger 6; Said secondary interchanger 6 and a refrigerator 7 formation loops are provided with automatic regulating valve 8 in the chilled water import department of secondary interchanger 6.
Operation principle is: air inlet is reduced to about 50 ~ 60 ℃ about one-level interchanger temperature is by 100 ℃, is reduced to about 20 ~ 30 ℃ by spray column again, drops to the technology wind about 12 ℃ by the secondary interchanger at last.After installing the secondary interchanger additional, originally heat exchanger advances cooling with chilled water, can change cooling water into now.
Claims (1)
1. spray column heat-exchange device; It comprises spray column (1), one-level interchanger (2), spray pump (3) and heat exchanger (4); The air outlet of said one-level interchanger (2) links to each other with the air inlet of spray column (1); The delivery port of said spray column (1) links to each other with the water inlet of spray pump (3); The delivery port of said spray pump (3) links to each other with the water inlet of heat exchanger (4), and the delivery port of said heat exchanger (4) links to each other with the interior nozzle (5) of spray column (1), it is characterized in that the air outlet of said spray column (1) is connected with secondary interchanger (6); Said secondary interchanger (6) and a refrigerator (7) form the loop, are provided with automatic regulating valve (8) in the chilled water import department of secondary interchanger (6).
