Abstract

A flue gas seawater desulfuration deep tunnel aeration device consists essentially of a seawater intake, a downcomer, a mixed intake, an air intake, an ascension pipe and a seawater outlet. When the aeration seawater is added into the downcomer via seawater intake, the mixed seawater is added into the downcomer via the mixed intake. After the aeration seawater is mixed with the mixed seawater during the process of the down flowing, the sulfur dioxide in the aeration seawater is converted into sulfite. The air with pressure is added into the downcomer via air intake and continues flowing downwards, and then flows upwards in the ascension pipe. With contact with seawater deeper than thirty meters and the diffusion in the water, the oxygen in the air dissolves into the seawater efficiently and oxidizes the sulfite into sulfate, releasing carbon dioxide. The quality-recovered seawater is drained out when coming to the outlet. The seawater desulfuration deep tunnel aeration device has advantages of low investment, less land occupation, remarkable energy saving and high aeration efficiency.

Description

Sea water desulfuration deep well aeration device

Affiliated technical field

The utility model relates to a kind of flue gas sea water desulfuration aerating apparatus, is applicable to that the heat-engine plant desulfurized minimizing aeration that cuts down the consumption of energy in beach accounts for the aerating apparatus in place.

Background technology

The aeration of beach flue gas desulphurization normally adopts perforated pipe aerating regulation or other conventional aerating apparatuss now.Not only coefficient of oxygen utilization is low, the need gas consumption is big, energy consumption is high, facility is complicated for these aerating apparatuss, also will build the no small aeration tank of occupation of land, and this is heat-engine plant desulfurized to very nervous beach, land for building to be a no small burden.

Goal of the invention

The purpose of this utility model provides a kind of seawater aeration new device, can significantly improve coefficient of oxygen utilization, significantly cut down the consumption of energy, make the no small aeration tank of occupation of land to become the aeration vertical shaft that takes up little room, and significantly reduced construction cost, also significantly reduced working cost.

Summary of the invention

Principle of work of the present utility model is, the solubleness of the solubleness of oxygen in water under the normal pressure under the high pressure; The aeration vertical shaft takes up an area of few, and fabrication cost is low.

The purpose of this utility model is achieved in that in underground construction as well downtake and upcast, at deep under ground, downtake and upcast two pipes link.Seawater ginseng hybrid junction mouth and aeration air interface are set at the middle part of downtake, after the seawater for the treatment of aeration enters from the upper inlet of downtake, down mixing sea water mixing with the ginseng that enters into downtake in the flow process, treat that the Sulphur Dioxide in the seawater of aeration becomes sulphite, because the air that ginseng is mixed is in underground deep water mesohigh place, the solubleness of oxygen solubility under the normal pressure, and make the sulphite that is dissolved in the seawater change into vitriol rapidly, and emit carbonic acid gas, the seawater that ginseng has been mixed air continues aeration and rises mobile through downtake and the upcast two pipes back, place that links, after flowing out upcast, carbonic acid gas enters in the air, and the seawater that recovers water quality is discharged to the extra large pipe from the aeration mouth of pipe.

Beneficial effect

Because far above conventional aeration pressure, the amount that the airborne oxygen of aeration dissolves in the seawater compares conventional high times, and actual aeration air quantity is significantly reduced in pipe bottom water depth pressure, it is very remarkable to economize on electricity; The construction cost of downtake and upcast also is lower than the aeration tank simultaneously, and its floor space is also few.

Description of drawings: the utility model is further specified below in conjunction with accompanying drawing.

Fig. 1. be the deep-wall type aeration yarn system of the concentric structure of downtake in upcast.

Fig. 2. being downtake is being the deep-wall type aeration yarn system of U type tubular construction with upcast.

Label in the accompanying drawing: seawater inlet (1), downtake (2), ginseng is sneaked into mouthful (3), gas inlet (4), upcast (5), tube wall (6), earth (7), seawer outlet (8), downtake (9), upcast (10).

At Fig. 1. middle downtake (2) in upcast (5) and two pipes coaxial, when the seawater of desiring aeration flows downward after seawater inlet (1) enters in the downtake (2); The sulfurous gas that is dissolved in the seawater during for fear of the washing flue gas is overflowed from seawater, be provided with ginseng at downtake (2) nearby from aeration seawater inlet (1) and sneak into mouthful (3), ginseng is mixed seawater and is added through this, thereby increased the alkalinity in the seawater, convert the sulfurous gas that is dissolved in the seawater to sulphite, and continue to flow downward.The Geng Xiachu that sneaks into mouthful (3) in ginseng is provided with gas inlet (4),, and is spread apart in the seawater that flows downward again in this joins downtake (2) by the air of Aeration fan force feed fork-like farm tool used in ancient China.Since the seawater place that has blasted air from upper orifice have more than ten meter dark, reach tens meters down deeplyer, therefore the oxygen that is dissolved in the seawater exceeds more than ten times than routine, sulphite in the seawater just can convert vitriol to fully the way of upcast (6) of flowing through again from the lower port outflow of downtake (2), and emit carbonic acid gas, the seawater of discharging from aeration seawer outlet (8) is the seawater of complete allow compliance with emission standards.

At Fig. 2. middle basic condition and Fig. 1. in 8 identical, just upcast and downtake is not concentric structure but by upcast (9) and downtake (10) formation U type structure.

Claims

1. flue gas sea water desulfuration deep well aeration device, by seawater inlet (1), downtake (2), ginseng is sneaked into mouthful (3), gas inlet (4), upcast (5), seawer outlet compositions such as (8), it is characterized in that: downtake and upcast have the degree of depth greater than 30 meters underground, seawater inlet (1) upper surface of (2) in downtake, ginseng is sneaked into the middle and upper part that mouthful (3) are connected on downtake (2), the middle and upper part ginseng that gas inlet (4) is connected on downtake (2) sneak into mouthful (3) below, the lower surface mouth of pipe UNICOM of downtake (2) and upcast (5), upcast (5) the upper surface mouth of pipe connects seawer outlet (8) and UNICOM's atmosphere.

2. according to the described sea water desulfuration deep well aeration of claim 1. device, it is characterized in that downtake with upcast both can be the downtake (2) of coaxial inner conductor and the sleeve structure of upcast (5), also can downtake (9) with upcast (10) two pipe bottoms link the U tubular construction.
