Description

Vertical desulfurizing tower
Technical field
The invention belongs to filed of flue gas purification, especially relate to a kind of vertical desulfurizing tower.
Background technology
At present, Wet Flue Gas Desulfurization Technology because of desulfuration efficiency high, stable performance, be widely used in various gas cleaning engineering, but along with people are to the increase day by day of the Air Pollutant Emission attention rates such as PM2.5, originally the absorption tower of removing sulfur dioxide or nature draught cooling tower is only provided cannot to have met the requirement of minimum discharge, existing design is usually by desulfuration absorbing tower, wet electrical dust precipitator, chimney is separated and arranges, other flue gas processing device so additional then faces and needs land occupation, the drawbacks such as adding cost, the a lot of old power plant of Give and old smoke gas treatment project reconstruction bring very large restriction and difficulty.Existing integral type tower body is generally the identical or housing structure that diminishes gradually of diameter from bottom to top of upper and lower diameter, and this designs the reaction characteristics do not fully not taken into account in tower body different parts, affects the reaction efficiency of whole technological process.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the vertical desulfurizing tower that a kind of floor space is little, contaminant removal efficiency is high, removal effect is good.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vertical desulfurizing tower, comprise the first tower body being provided with slurry pool, the second tower body being provided with reaction unit, be provided with the 3rd tower body and chimney of wet electrical dust precipitator, described first tower body, the second tower body, the 3rd tower body and chimney are vertically tightly connected the tower body being formed and have variable-diameter structure from bottom to top.The demand of tower body to soil of vertical structure is less, and then reduces financial cost.
Further, the second tower body is provided with the passage entered for flue gas, and this passage is horizontal by the angle of 7-15 °.Promote flue gas toward with the tower body of passage right opposite in flow, make flue gas more uniformly flow to reaction unit.
Further, be connected by cone section between the second tower body and the 3rd tower body, the angle of this cone section outer wall and horizontal plane is α, 45 ° of < α < 90 °.
Further, the diameter of the second tower body is D 2, 4m < D 2< 16m.
Further, the diameter of the 3rd tower body is D 3, 8m < D 3< 24m.Between different functional units, change the flow velocity of flue gas by cone section, enable the flue gas flow rate that flue gas fully adapts to required for different units different phase, reduce the running resistance of whole system, reduce energy consumption.
Further, described 1≤D 2: D 3≤ 2.Ensure the stability of tower body.
Further, the height of tower body is 45-80m.
Further, reaction unit comprises 1-3 demister layer, a 1-6 spraying layer and 1-2 synergistic device layer.Both ensure that desulfuration efficiency, control cost simultaneously.
Further, spraying layer has the back pressure of 6-8mH.
Further, the support for supporting tower body is arranged with outside tower body.
The invention has the beneficial effects as follows that Stability Analysis of Structures simplifies system architecture, and eliminate the Flue duct design that routine arranges middle complexity, floor space is little, and then reduces cost, and the removal efficiency of pollutant is high, and removal effect is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Better the present invention program is understood in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
With reference to shown in Fig. 1, in figure, the direction of arrow is flow of flue gas direction, a kind of vertical desulfurizing tower, the whole height of tower body is 45-80m, comprise the first tower body 1 being provided with slurry pool, the second tower body 2 being provided with reaction unit, the 3rd tower body 3 being provided with wet electrical dust precipitator 31 and chimney 4, second tower body 2 is sealedly connected on the top of the first tower body 1 by the first cone section 51,3rd tower body 3 is sealedly connected on the top of the second tower body 2 by cone section 32, chimney is sealedly connected on the top of the 3rd tower body 3 by the second cone section 52, and the diameter of the second tower body 2 is D 2, D 2for 4-16m is arranged, the diameter of the 3rd tower body 3 is D 3, D 3for 8-24m is arranged, and D 2with D 3ratio be that 1-2 is arranged, be connected by the little cone section 32 of the large lower section in cross section, top between the second tower body 2 with the 3rd tower body 3, the sidewall of this cone section 32 is horizontal by the setting of α angle, and 45 ° of < α < 90 °.The sidewall of the second tower body 2 is provided with the passage 21 entered for flue gas, and this passage 21 is arranged horizontal by the angle of 7-15 °.Reaction unit comprises the demister layer 22 arranged from top to bottom, and its quantity is 1-3, spraying layer 23, and its quantity is 1-6, synergistic device layer 24, and its quantity is 1-2, and in order to improve reaction effect, spraying layer 23 has the back pressure of 6-8mH.The base portion of chimney is provided with reinforcement, and its exit is provided with brokenly solar or lunar halo.In order to improve the stability of tower body, the support for supporting tower body can also be set in tower body periphery.
