Description
Technical field
This utility model is related to a kind of elimination " white cigarette " device.
Background technology
With the continuous improvement of environmental requirement, almost all of station boiler, steel works sintering unit are required for plus removable
Sulfur device, the most of desulfurizer of China adopts wet desulphurization, and the method desulphurization reaction speed is fast, efficiency high, desulfurization add
Plus agent utilization rate is high, can reach 90% desulfurization degree, makes sulfur dioxide (SO2) emissions meet related request.But while flue gas Jing desulfurization system
Substantial amounts of moisture can be taken away after system, and the newly-increased fired power generating unit of China build the western coal-producing area in mostly, west area water resource compares
Scarcity, has further deepened the contradiction between environmental resource and economic development.If the moisture in flue gas can be reclaimed and in addition
Recycling, provides the fired power generating unit construction of water-deficient area and supports energetically, realizes good social benefit.
On the other hand, 50 ~ 60 DEG C of wet flue gas corrosivity are stronger, and existing chimney has to pass through anti-corrosion transformation when just can be long
Between use, and chimney breast produce substantial amounts of " white cigarette ", give the illusion of a large amount of pollutant emissions.If can be by after desulfurization
Flue-gas temperature bring up to 80 DEG C or so, then can solve the above problems.
Utility model content
1st, technical problem to be solved：
Eliminate " white cigarette ", making chimney need not move through anti-corrosion transformation can also use for a long time.
2nd, technical scheme：
In order to solve problem above, this utility model provides a kind of tubular type flue gas and receives water elimination " white cigarette " device, including
Heat exchanger tube 1, is provided with 3 pieces of tube sheets 7, and the tube sheet 7 is orifice plate, and the heat exchanger tube 1 is arranged in the hole of tube sheet, and 3 pieces of tube sheets 7 will be changed
Heat pipe is divided into two regions, and top is heating region, and lower section is cooled region, and the tube sheet 7 is externally provided with housing 2 and tube sheet 7 is solid
Fixed connection, is provided with wet flue gas pipeline 3 and links into an integrated entity with housing 2, and perpendicular to tube sheet 7, the heating region and cooling zone
Domain is designed with air inlet and gas outlet on housing 2.
The gas entered in the air inlet of the heating region be high-temperature gas, the gas that the air inlet in the cooled region enters
Body is air.
Described hot-gas temperature is 125-135 degree, and the temperature of the air is ambient temperature.
Intersection inside every heat exchanger tube in heating region and cooled region has been provided with demister 9.
The gas outlet of the heating region and desulfurizing tower air inlet connect.
The gas outlet of the cooled region and the air inlet connection of boiler.
3rd, beneficial effect：
The tubular type flue gas that this utility model is provided receives water elimination " white cigarette " device and eliminates " white cigarette " phenomenon, reduces flue gas pair
The corrosion of chimney, and substantial amounts of moisture can be reclaimed.
Description of the drawings
Fig. 1 structural representations of the present utility model.
Specific embodiment
This utility model is described in detail below by accompanying drawing.
As shown in figure 1, a kind of tubular type flue gas receives water eliminates " white cigarette " device, including heat exchanger tube 1,3 pieces of tube sheets 7, institute are provided with
It is orifice plate to state tube sheet 7, and the heat exchanger tube 1 is arranged in the hole of tube sheet, and heat exchanger tube is divided into two regions by 3 pieces of tube sheets 7, and top is
Heating region, lower section is cooled region, and the tube sheet 7 is externally provided with housing 2 and is fixedly connected with tube sheet 7, be provided with wet flue gas pipeline 3 with
Housing 2 links into an integrated entity, and perpendicular to tube sheet 7, the heating region and cooled region be designed with housing 2 air inlet and
Gas outlet.
Cooled region air inlet enter for cold air, the temperature from wet flue gas that wet flue gas pipeline 3 is entered is 55 DEG C, cold sky
The temperature of gas is ambient temperature, and the flow of cold air is adjustable.Thus, through the heat exchange of cooled region, wet flue gas temperature can
To reduce by 10 DEG C.The moisture of about 50.3g can be removed per 1kg dry flue gas, in cooled region and the thermal treatment zone inside every heat exchanger tube
Domain intersection has demister 9, and the water yield for absorbing is intercepted, reclaimed.For Large-scale machine set, the moisture of recovery is phase
When big.Cold air after heat exchange can be used as inlet air of boiler, due to temperature it is higher than ambient temperature, it is possible to save
It is about coal-fired, reduce specific energy consumption.
Wet flue gas after cooling enter heating region, and the temperature of the high-temperature gas that heating region air inlet enters is 125-
135 DEG C, wet flue gas temperature can be heated to 80 DEG C, then be discharged, original chimney need not do anti-corrosion transformation, also eliminate and regard
Feel pollution problem.High-temperature flue gas temperature after heat exchange can be down to 95 DEG C, subsequently into desulfurizing tower, because flue gas volume only has
Before transformation 90%, so the efficiency of desulfurizing tower also can be improved, can further reduce the emission level of pollutant.
Although this utility model is disclosed as above with preferred embodiment, they are not for limiting this utility model
, it is any to be familiar with this those skilled in the art, in the spirit and scope without departing from this utility model, can make various changes or retouch from working as,
Therefore protection domain of the present utility model should be by being defined that claims hereof protection domain is defined.
