Description
Technical field
This utility model relates to desulfurizer field, specially one all gas turbulent current type high-efficient desulfurizers.
Background technology
Power plant has the fume desulphurization method of certain application achievement mainly to have the most at home: recirculating fluidized bed flue gas semidry method, seawater method, wet-type ammonia, limestone/lime-gypsum wet method.Process for flue gas desulfurization by limestone/lime-gypsum wet technique is technology flue gas desulfurization technique the most ripe, most widely used, and the means of flue gas desulfurization of power plant device of China about 96% is all to use this kind of technique.
This technique is segmented into again many classifications according to the difference of absorption tower structural shape, wherein applies more absorption tower tower to have: bubble tower, liquid column tower and spray column.Spray column is the pyramidal structure that application is most, and the wet desulphurization device of domestic more than 90% is all the spray column used.Spray column is the spraying downwards (Bidirectional nozzle can be sprayed the most up and down) by Multi-layer sprinkling layer, contacts absorption SO therein with flue gas adverse current2Owing to there being Multi-layer sprinkling layer, spray coverage rate on cross section, absorption tower can reach the highest, thus spray column has the advantage that 1. desulfuration efficiency is high: desulfuration efficiency typically can reach more than 95%, can be reached the desulfuration efficiency of more than 97% by the increase spray number of plies and spray flux；2. system reliability and availability are high: although spray column still also exists absorption tower corrosion, wear, fouling and blockage problem, but by the optimal control run, substantially can control within the acceptable range, will not the operation of system for restricting；3. system suitability is strong: in the design phase, can design low coal-fired sulphur content during different absorption tower parameters adapts to.
But in spray column, every layer of corresponding slurry circulating pump of spraying layer is for slurry, owing to circulating pump and the spray number of plies are more, particularly medium-high sulfur coal, and therefore absorption tower is the highest, and slurry pool of absorption tower power consumption the biggest, circulating pump is higher.Sulfur dioxide (SO2) emissions limit value according to " fossil-fuel power plant atmospheric pollutant emission standard " (GB13223-2011) desulfuration efficiency≤35mg/m3, emission request becomes and is sternly becoming tight, active service unit is faced with transformation, new-built unit must is fulfilled for up-to-date discharging standards, so must develop further in desulfurization technology.
Utility model content
The purpose of this utility model is to provide one all gas turbulent current type high-efficient desulfurizers, improves desulphurization reaction efficiency further and to the capturing ability of dust in desulfurization fume.
For achieving the above object, this utility model following technical scheme of offer: one all gas turbulence type desulfurizers, including tower body, serosity oxidation pond, absorption tower entrance, double spray nozzle, absorption tower outlet it is provided with from bottom to top in tower body, also set up in described tower body and turn to current equalizer, described current equalizer is turned to be arranged on below described pair of spray nozzle, absorption tower entrance top.Described turning to current equalizer to be made up of all gas turbulent flow unit, described all gas turbulent flow unit includes all gas turbulent flow housing, spiral type guide vane and positioner.
Preferably, the described all gas turbulent flow unit in current equalizer that turn to are uniformly distributed.
Preferably, described positioner is locating ring.
Preferably, described all gas turbulent flow unit is built-in with 2-10 spiral type guide vane, is more preferably provided with 2-6 spiral type guide vane.
Preferably, described pair of spray nozzle forms one layer in the horizontal direction and divides equally layout, and described pair of spray nozzle is 30 ° with horizontal direction angle, and described pair of spray nozzle is arranged on the bottom exported on described absorption tower.
Preferably, described absorption tower entrance and absorption tower outlet are each provided on described tower body side.
Compared with prior art, all gas turbulence type desulfurizer simple in construction of the present utility model, easy for installation, absorption tower inlet flue gas is carried out uniform, and by flue gas being turned to formation turbulent flow, add desulphurization reaction efficiency, and improve the capturing ability of dust in desulfurization fume, it is possible to meet different load operating mode, thus reach efficient desulfurization and dedusting effect.

Fig. 1 is the structural representation of this utility model all gas turbulence type desulfurizers；
Fig. 2 is the structural representation that this utility model turns to current equalizer；
Fig. 3 is the cross-sectional view that this utility model turns to current equalizer.
In figure: 1 serosity oxidation pond, 2 turn to current equalizer, 201 all gas turbulent flow unit, the 3 pairs of spray nozzles, 4 absorption tower entrances, 5 absorption towers outlets, 6 all gas turbulent flow housing, 7 spiral type guide vanes, 8 locating rings, 9 tower bodies.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refering to Fig. 1-3, this utility model provides one all gas turbulent current type high-efficient desulfurizers, including tower body, serosity oxidation pond 1, absorption tower entrance 4, double spray nozzle 3, absorption tower outlet 5 it is provided with from bottom to top in tower body, also set up in described tower body 9 to be made up of some all gas turbulent flow unit 201 and turn to current equalizer 2, described current equalizer 2 is turned to be arranged on below described pair of spray nozzle 3, above absorption tower entrance 4.Described all gas turbulent flow unit 201 includes all gas turbulent flow housing 6, spiral type guide vane 7, and locating ring 8.
Described spiral type guide vane 7 uses concentric connection to divide equally layout with described all gas turbulent flow housing 6, locating ring 8, described all gas turbulent flow unit 201 is built-in with 6 spiral type guide vanes 7, described pair of spray nozzle 3 forms one layer in the horizontal direction and divides equally layout, described pair of spray nozzle 3 is 30 ° with horizontal direction angle, described pair of spray nozzle 3 is arranged in the bottom of described absorption tower outlet 5, and described absorption tower entrance 4 and absorption tower outlet 5 are each provided on described tower body 9 side.
