Abstract
The invention relates to a molten salt furnace tail gas heat exchanger with a preservative effect. The molten salt furnace tail gas heat exchanger with the preservative effect comprises a deaerator and a water-treatment device. The deaerator comprises a water outlet, a water inlet, a spent steam outlet and a steam inlet. The water outlet of the deaerator is connected with a water inlet of an economizer. The water inlet of the deaerator is connected with a water outlet of the water-treatment device through a pump. The spent steam outlet of the deaerator is connected with a condenser. The steam inlet of the deaerator is connected with a steam outlet of a smoke evaporator. Due to the fact that deaerator is additionally arranged, the molten salt furnace tail gas heat exchanger with the preservative effect is stable in deoxidization effect, is not only capable of eliminating oxygen, but also capable of eliminating carbon dioxide and nitrogen. Salt content is not increased in deoxidized water. Therefore, the molten salt furnace tail gas heat exchanger with the preservative effect is capable of utilizing self-produced steam to effectively avoid corrosion of equipment, is capable of saving energy, is capable of saving materials and prolonging service life of the equipment and possesses considerable economic benefit.
Description
Technical field
The present invention relates to a kind of tail gas, particularly a kind of tail gas with antisepsis.
Background technology
Often dissolve in water for industrial use by gases such as oxygen, nitrogen, carbon dioxide, the wherein existence of oxygen and carbon dioxide is to the equipment such as boiler corrosion very easily.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 higher, and its solubility is just less.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 water just can be overflowed, and its shortcoming is many with vapour.
Summary of the invention
The technical problem to be solved in the present invention is: in order to remove oxygen, carbon dioxide, avoid the corrosion to tail gas, the invention provides a kind of tail gas with antisepsis.
the technical solution adopted for the present invention to solve the technical problems is: a kind of tail gas with antisepsis, it comprises molten salt furnace, flue gas evaporator for generation of steam, economizer for generation of 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 water inlet and is connected with economizer, the water inlet of described oxygen-eliminating device is connected delivery port and is connected by pump with water treatment facilities, the waste vapour outlet of described oxygen-eliminating device is connected with condenser, the steam (vapor) outlet that the steam inlet of described oxygen-eliminating device connects flue gas evaporator connects.
Described oxygen-eliminating device is thermal spraying formula oxygen-eliminating device.
The invention has the beneficial effects as follows: the tail gas with antisepsis of the present invention, increased oxygen-eliminating device, the steam that energy 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 deoxygenation in water.Therefore, this tail gas with antisepsis can utilize self steam effectively to avoid the corrosion of equipment, but energy savings can be saved service life of material and extension device, has very considerable economic benefit.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation that the present invention has the optimum embodiment of tail gas of antisepsis.
In 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, 9-3, waste vapour outlet, 9-4, steam inlet, 10, pump, 11, water treatment facilities.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, the present invention has the structural representation of the optimum embodiment of tail gas of antisepsis.a kind of tail gas with antisepsis, it comprises molten salt furnace 1, flue gas evaporator 2 for generation of steam, economizer 3 for generation of hot water, air preheater 4, desulfurizer 5, dust arrester 6, cryogenic heat exchanger 7 and chimney 8, 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 water inlet that the delivery port 9-1 of oxygen-eliminating device 9 is connected with economizer connects, the delivery port that the water inlet 9-2 of oxygen-eliminating device 9 is connected with water treatment facilities connects by pump 10, the waste vapour outlet 9-3 of oxygen-eliminating device 9 is connected with condenser, the steam (vapor) outlet that the steam inlet 9-4 of oxygen-eliminating device 9 connects flue gas evaporator 2 connects.
Oxygen-eliminating device 9 is thermal spraying formula oxygen-eliminating device.
This tail gas with antisepsis has increased oxygen-eliminating device 9, this equipment deaerating effect is stable, utilize the steam with certain pressure of introducing flue gas evaporator 2 will be heated to from the water of water treatment facilities 11 boiling, the oxygen that finally is delivered in the feedwater of economizer 3 is overflowed because solubility reduces, again the oxygen of overflowing is discharged from waste vapour outlet 9-3 with the steam that does not condense on a small quantity, to guarantee feed-water quality.In addition, the equipment of this thermal de-aeration can also be removed carbon dioxide and nitrogen; Do not increase salt content after deoxygenation in water.This steam of tail gas with antisepsis is self-sufficient all the time, and can supply with outside the use.Therefore, this tail gas with antisepsis can utilize self steam effectively to avoid the corrosion of equipment, but energy savings can be saved service life of material and extension device, has very considerable economic benefit.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
