Description
（One）Technical field
Atmospheric environment protection technical field is the utility model is related to, more particularly to a kind of magnesium method flue gas desulphurization absorption tower.
（Two）Background technology
Magnesium method flue gas desulphurization have technique simple, efficiency high, it is stable the characteristics of, while have that MgO activity is high, system
Simply, it is less scaling block, take up an area it is small, be easily achieved many advantages, such as Automatic Control, magnesium method flue gas desulphurization technique will be by
Step is more widely used, and just has been to be concerned by more and more people.
Magnesium method flue gas desulphurization technique has many application achievements all over the world, wherein having applied 100 in Japan
Multiple projects, the power station 95% in Taiwan are to use the ground such as magnesium oxide method, the U.S., Germany all to apply.Because the hydrolysis of magnesia is produced
Thing solubility and reactivity will due to calcium oxide, therefore under conditions of identical desulfurization degree is reached, its desulfurizing agent and sulphur
Mol ratio will be less than lime stone or lime.Simultaneously as the molecular weight of magnesia is less than lime stone or calcium oxide, even in identical
Desulfuration efficiency under, its doctor solution consumption will also be less than calcium desulfurizing agent.But because the MgO prices of foreign countries are higher, China is introducing
During external desulfurization technology mainly based on calcium method, practical application of the magnesium processes desulfurization technology in means of flue gas desulfurization of power plant is less, but I
State-owned abundant oxidation magnesium resource, reserves account for more than the 90% of whole world total amount, therefore the means of flue gas desulfurization of power plant in China can be because of ground
Suiting measures to different conditions, develop magnesium processes desulfurization.
（Three）The content of the invention
The utility model is in order to make up the deficiencies in the prior art, there is provided a kind of technique is simple, stable, energy-saving and emission-reduction
Magnesium method flue gas desulphurization absorption tower.
The utility model is achieved by the following technical solution：
A kind of magnesium method flue gas desulphurization absorption tower, including lower section set gas approach, top to set exhanst gas outlet, inside certainly
The lower and upper absorption tower that spraying layer and demister are set, it is characterised in that：The absorb the bottom of the tower is provided with its inside of connection
Material kettle, the circulation pipe of shower on connection spraying layer is installed on material kettle, circulating pump is installed on circulation pipe；In material kettle
Side agitator is installed and connects the oxygen-supplying tube of oxidation fan.
The utility model is by absorption tower and the integrally connected of material kettle, by the absorption in traditional magnesium processes sulfur removal technology, oxygen
Chemical combination is integrated, and is directly absorbed, aoxidized in absorption tower, is realized in the tower of material and is circulated, eliminates tower outer circulation
Auxiliary device, save investment and floor space.
More excellent technical scheme of the present utility model is：
PH meter is installed, being provided with desulfurizing agent on material kettle adds mouth, passes through the real-time detectable substance of pH meter on the circulation pipe
The acid-base value of material, it is easy to add desulfurizing agent in time.
The bottom of the material kettle is provided with delivery pipe, and excavationg pump is provided with delivery pipe, by excavationg pump and delivery pipe,
Discharge is timed to material in tower, is easy to scavenger precipitation.
The utility model is simple in construction, easy to use, simplifies the technological process of magnesium method flue gas desulphurization, saves project throwing
The floor space of money and device, does not influence the stable operation of device, Practical Benefit highly significant.
（Four）Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure, 1 absorption tower, 2 gas approach, 3 exhanst gas outlets, 4 spraying layers, 5 demisters, 6 material kettles, 7 circulation pipes, 8 follow
Ring pump, 9 side agitators, 10 oxygen-supplying tubes, 11 oxidation fans, 12 pH meters, 13 desulfurizing agents add mouth, 14 excavationg pumps.
（Five）Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The embodiment includes lower section and sets gas approach 2, top to set
Exhanst gas outlet 3, the internal absorption tower 1 that spraying layer 4 and demister 5 are set from bottom to top are put, the bottom of absorption tower 1 is provided with company
Lead to its internal material kettle 6, the circulation pipe 7 of shower on connection spraying layer 4 is installed on material kettle 6, is provided with circulation pipe 7
Circulating pump 8；Side agitator 9 is installed in material kettle 6 and connects the oxygen-supplying tube 10 of oxidation fan 11；Installed on the circulation pipe 7
There is pH meter 12, desulfurizing agent is provided with material kettle 6 and adds mouth 13；The bottom of the material kettle 6 is provided with delivery pipe, on delivery pipe
Excavationg pump 14 is installed.
The flue gas Mg (OH) with circulated sprinkling from bottom to top2The reverse haptoreaction of solution, remove the SO in flue gas2, generation
MgSO3And MgSO4, in the material kettle 6 for eventually falling into the bottom of absorption tower 1, at the same be passed through excess air in the bottom of material kettle 6 will
MgSO3It is oxidized to MgSO4, material kettle 6 is interior to set side agitator 9, prevents material precipitation from ensureing the normal operation of system.Absorb
The pH value of material in 12 real-time monitoring towers is counted when tower 1 is run by the PH on circulation pipe 7, required by pH value close to reaction most
During low value, the pH value that mouth 13 added in desulfurizing agent stabilizer in good time is added by desulfurizing agent, until material pH value reaches just in tower
Normal standard.
