Description
Technical field
The utility model belongs to Wet Flue Gas Desulfurization Technique field more particularly to a kind of flue gas condensing for wet desulphurization and removes
Dirt integrated apparatus.
Background technique
A large amount of flue gas can be generated in the production processes such as coal fired power generation, chemical industry, steel, weaving, papermaking and mining, for protection
Environment is not contaminated, and flue gas needs to carry out desulfurization process before discharge.Currently, generalling use wet desulfurizing process to handle combustion
The flue gas that coal generates.Wet desulphurization is due to being gas liquid reaction, and desulphurization reaction speed is fast, high-efficient, sulfur-removing additives utilization rate
Height when such as making desulfurizing agent with lime, as Ca/S=1.03, that is, can reach 90% or more desulfurization degree.
Flue gas after desulfurization is saturated flue gas, it appears that discharge is " white cigarette ", for the vision for meeting emission request and people
It is beautiful, it is also necessary to " flue gas takes off white ", but existing flue gas takes off whitening method, and system structure is complicated, the lifting temperature of needs is larger, energy
Consumption is high, not to flue gas condensing, is not also washed flue gas to have the function that dedusting again, is unfavorable for energy-saving and emission-reduction.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can be cold to flue gas condensing but also the flue gas of dedusting
Solidifying and dust removal integrated plant achievees the effect that flue gas takes off white and again removes a part of pollutant in flue gas to flue gas condensing,
Flue gas is washed again and achievees the effect that flue gas ash removal, to overcome the shortcomings of the prior art.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of flue gas condensing and dust removal integrated plant, including absorption tower and chimney, it is characterised in that: further include having spray
Tower, spray piping and cooling pipe；Bottom has slurry pool in the spray column, and top has spraying layer, is located at spraying layer
The deduster of top and the outlet flue above deduster, the spray column side have the liquid level higher than the slurry pool
Smoke inlet and water inlet；The absorption tower connects the smoke inlet of the spray column by the first smoke pipeline, the spray column
Outlet flue also passes through the second smoke pipeline and connects the chimney；It is equipped with the first water pump in the spray piping, is connected to the spray
Between layer and the slurry pool；It is successively arranged the second water pump and cooling tower in the cooling pipe, is connected to the slurry pool
And between water inlet.
By adopting the above technical scheme, by increasing spray column, spray piping, cooling pipe, pass through spraying layer in spray column
Spray and deduster dedusting, can remove smoke in dust, and spray and can also reduce the temperature of flue gas to reach
To the effect of flue gas condensing.Water in slurry pool is supplied spraying layer by the first water pump by spray piping.Since shower water is with cigarette
After gas heat exchange, the coolant-temperature gage in slurry pool can be increased, and to guarantee that shower water maintains lower temperature, cooling pipe passes through the second water
Water in slurry pool is evacuated to cooling tower and cooled down by pump, is sent again again through the cooled water of cooling tower to slurry pool.
In further improvement of the utility model, the spray piping between the first water pump and the spraying layer
Pipeline section on connect upper discharge line, be equipped with valve in the discharge line.By increasing discharge line, opened in discharge line
When, the water in a part of slurry pool can be discharged, and slurry pool is discharged in part dust, impurity in slurry pool in turn, into
And avoid the water for spray more and more dirtier.
In specific embodiment of the present invention, the spray piping has two；The cooling pipe include two simultaneously
The cooling tower of connection and three pipeline sections between the cooling tower and the slurry pool are equipped with the second water in every pipeline section
Pump.
By described in detail above, it can be seen that the utility model has the advantages that can be to flue gas condensing but also dedusting.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, flue gas condensing and dust removal integrated plant as shown in Figure 1, including absorption tower 100, chimney 200,
Spray column 300, spray piping 400 and cooling pipe 500.
Wherein, the front on absorption tower 100 is provided with sequentially connected sintering machine 101, electrostatic precipitator 102, air-introduced machine
103, air-introduced machine 103 is ultimately connected on the smoke inlet on absorption tower 100.
Bottom has slurry pool 301 in spray column 300, and top has spraying layer 302, removing above spraying layer 302
Dirt device 303 and the outlet flue 304 above deduster 303,300 side of spray column have the liquid level higher than slurry pool 301
Smoke inlet 305 and water inlet 306.
Absorption tower 100 connects the smoke inlet 305 of spray column 300, the outlet flue of spray column 300 by the first smoke pipeline 104
304 also connect chimney 200 by the second smoke pipeline 105.
Spray piping 400 has two, and the first water pump 401 is equipped in every spray piping 400；Spray piping 400 is discharged
End connection spraying layer, water inlet end connect slurry pool 301.
Cooling pipe 500 is comprising two cooling towers 501 in parallel and three between cooling tower 501 and slurry pool 301
Pipeline section, be equipped with the second water pump 502 in every pipeline section.
In the present embodiment, the first water pump 401 uses big flow water pump, and flow is (2500m3/h)；Second water pump 501
Using small flow water pump, flow is (850m3/h).
Corresponding position is provided with respective valves in spray piping 400 and cooling pipe 500, for realizing the on-off of pipeline.
In the present embodiment, also increase discharge line 600, positioned at the in the drainage pipeline 600 and two articles of spray pipings 400
Pipeline section connection between one water pump 401 and spraying layer 302, the drainage pipeline 600 are equipped with valve 601.By increasing discharge line
600, when discharge line 600 is opened, the water of a part of slurry pool 301 can be discharged, and in turn will be in slurry pool 301
Part dust, impurity are discharged slurry pool, and then avoid the water for spray more and more dirtier.The water of discharge can be arranged to former demister
Pond 602 is rinsed to recycle.
It is above exactly the flue gas condensing and dust removal integrated plant of the utility model, working method are as follows:
The flue gas being discharged from absorption tower 100 enters spray column 300, by the spray of spraying layer 302 in spray column 300 and removes
The dedusting of dirt device 303, can remove smoke in dust, and spray and can also reduce the temperature of flue gas to reach cold to flue gas
Solidifying effect.Water in slurry pool is supplied spraying layer by the first water pump 401 by spray piping 400.Since shower water is with flue gas
After heat exchange, the coolant-temperature gage in slurry pool 301 can be increased, and to guarantee that shower water 301 maintains lower temperature, cooling pipe 500 is logical
It crosses the second water pump 501 water in slurry pool 301 is evacuated to cooling tower 502 and cool down, again again through the cooled water of cooling tower 502
It send to slurry pool 301.In actual moving process, water can be mended in case of being lost into slurry pool 301 in slurry pool 301
Water.
