Technical field
The utility model relates to a kind of molten salt furnace tail gas heat exchanger, particularly a kind of molten salt furnace tail gas heat exchanger with antisepsis.
Background technology
Often dissolve by gases such as oxygen, nitrogen, carbon dioxide in the water for industrial use, the wherein existence of oxygen and carbon dioxide is very easily corroded equipment such as boilers.Corrosion especially severe when especially aerobic exists.Gas is under different pressure and temperatures, and the solubility in water is different, and the temperature of water is high more, and its solubility is just more little.Traditional thermal de-aeration method is to utilize external steam to make the water heating, reduces the wherein solubility of oxygen, and the oxygen in the water just can be overflowed, and its shortcoming is many with vapour.
The utility model content
The technical problem that the utility model will solve is: in order to remove oxygen, carbon dioxide, avoid the corrosion to the molten salt furnace tail gas heat exchanger, the utility model provides a kind of molten salt furnace tail gas heat exchanger with antisepsis.
The utility model solves the technical scheme that its technical problem adopted: a kind of molten salt furnace tail gas heat exchanger with antisepsis; It comprises molten salt furnace, is used to produce the smoke evaporative device of steam, the economizer that is used to produce hot water, air preheater, desulfurizer, dust arrester, cryogenic heat exchanger and chimney; Also comprise oxygen-eliminating device and water treatment facilities; Described oxygen-eliminating device comprises delivery port, water inlet, waste vapour outlet and steam inlet; The delivery port of described oxygen-eliminating device is connected with the water inlet of economizer; The water inlet of described oxygen-eliminating device is connected through pump with the delivery port of water treatment facilities, and the waste vapour outlet of described oxygen-eliminating device is connected with condenser, and the steam (vapor) outlet that the steam inlet of described oxygen-eliminating device connects the smoke evaporative device connects.
Described oxygen-eliminating device is a thermal spraying formula oxygen-eliminating device.
The beneficial effect of the utility model is: the molten salt furnace tail gas heat exchanger with antisepsis of the utility model, increased oxygen-eliminating device, and the steam that ability use device self produces is removed oxygen, and can also remove carbon dioxide and nitrogen; Deaerating effect is stable; Do not increase salt content after the deoxygenation in the water.Therefore, this molten salt furnace tail gas heat exchanger with antisepsis can utilize self steam effectively to avoid corrosion on Equipment, but energy savings can save material and prolong service life of equipment, have very considerable economic.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation that the utlity model has the optimum embodiment of molten salt furnace tail gas heat exchanger of antisepsis.
Among the figure 1, molten salt furnace, 2, smoke generator, 3, economizer, 4, air preheater; 5 desulfurizers, 51, the dry type alkaline adsorbent, 6, dust arrester, 7, cryogenic heat exchanger; 8, chimney, 9, oxygen-eliminating device, 9-1, delivery port, 9-2, water inlet; The outlet of 9-3, waste vapour, 9-4, steam inlet, 10, pump, 11, water treatment facilities.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utlity model has the structural representation of the optimum embodiment of molten salt furnace tail gas heat exchanger of antisepsis.A kind of molten salt furnace tail gas heat exchanger with antisepsis; It comprises molten salt furnace 1, be used to produce the smoke evaporative device 2 of steam, be used to produce economizer 3, air preheater 4, desulfurizer 5, dust arrester 6, cryogenic heat exchanger 7 and the chimney 8 of hot water; Also comprise oxygen-eliminating device 9 and water treatment facilities 11; Oxygen-eliminating device 9 comprises delivery port 9-1, water inlet 9-2, waste vapour outlet 9-3 and steam inlet 9-4; The delivery port 9-1 of oxygen-eliminating device 9 is connected with the water inlet of economizer 3; The water inlet 9-2 of oxygen-eliminating device 9 is connected through pump 10 with the delivery port of water treatment facilities 11, and the waste vapour outlet 9-3 of oxygen-eliminating device 9 is connected with condenser, and the steam (vapor) outlet that the steam inlet 9-4 of oxygen-eliminating device 9 connects smoke evaporative device 2 connects.
