Description
Technical field
The invention belongs to the gas purification technique field, particularly boiler fume desulfurizing and dedusting device structure design.
Background technology
Wet technique in the boiler fume desulfurizing and dedusting tower has a kind of spray column with cyclone at present.This tower comprises: tower body, be provided with gas approach, exhanst gas outlet and plasma discharge mouth at this tower body, be provided with slurry pump by linking to each other, the roots blower that links to each other with aeration tube in being arranged on tower inner bottom part liquid storage area from bottom to up at this tower, be connected the circulating pump in the circulating line that communicates with the shower of this liquid storage area on, and be arranged on the demister on this shower with it with plasma discharge mouth at the bottom of the tower; Also comprise be arranged under this tower internal sparger pipe, the cyclone on the gas approach, it is mainly by blind plate, swirl vane, cover tube, overflow launder, collecting tank, compositions such as overfall, overflow pipe, special-shaped adapter.
The course of work of this boiler flue gas desulfurization cyclone is: desulfurization slurry is evenly distributed to each blade, forms thin liquid layer.When passing through blade from bottom to top, air-flow produces the centrifugal motion of rotation.Make desulfurization slurry drop in collision cohesion on the tower wall.Under the effect of gravity, be pooled to collecting tank, and flow to by overfall, overflow pipe on the blind plate of next column plate, continue to repeat said process.
There is following point in above-mentioned boiler fume desulfurizing and dedusting tower:
1, because the gas-liquid contact time on the column plate is short, so desulfuration efficiency is on the low side, is about 80%, and is not suitable for CaCO3 and makes sulphur-fixing agent.(drawing from " sulphur polluted by nitrogen Way of Engineering Technology in Control of Underground and application thereof "), Guo Dongming write, and chemical industry is published);
2, sulphur hydrocyclone structure complexity, fouling easily, and desulfuration efficiency reduces with the tower diameter increase.
3, be tangential admission, the center forms the poor efficiency district easily.
4, similar other cyclones, its blade center is a solid, enters the back at flue gas and forms rotation and form the vacuum funnel in the center with desulfurization slurry, influences desulfuration efficiency and effect.
Summary of the invention
The objective of the invention is for overcoming the weak point of prior art, a kind of turbine type pressure charging acceleration fuel gas desulfurization gas wash tower is proposed, can be implemented in the shortest time, minimum space, under the minimum liquid-gas ratio, reach gas-liquid and fully contact, carry out the high speed mass transfer, improve high dedusting, desulfuration efficiency under the least energy consumption.
The turbine type pressure charging acceleration fuel gas desulfurization gas wash tower that the present invention proposes, comprise: the spray tower body, be provided with slurry pump by linking to each other, the roots blower that links to each other with aeration tube in being arranged on tower inner bottom part liquid storage area from bottom to up at this tower with plasma discharge mouth at the bottom of the tower, be arranged on shower on this liquid storage area, be connected with circulating line that this shower communicates in circulating pump, and be arranged on demister on this shower; It is characterized in that, be provided with gas approach, exhanst gas outlet and plasma discharge mouth in this spray tower body lower sides, top and bottom; Comprise that also the disturbance pump that is connected in the circulating line that communicates with tower inner bottom part liquid storage area territory, the turbo-supercharging that is arranged under this tower internal sparger pipe, on the gas approach quicken desulfurating dust removing device for flue gas.
Described turbo-supercharging quickens desulfurating dust removing device for flue gas and specifically comprises: housing, be fixed on the pipeline at this housing center, and be installed in a plurality of blades between this housing and the pipeline, the upper end of each blade links to each other with this housing, and the lower end is connected with pipeline; The lower end of this pipeline connects one and hides petticoat pipe, in this pipeline helix(ribbon type) agitator is installed, and this helix(ribbon type) agitator is to be arranged on this ducted banded in the shape of a spiral rectangular plate.
Described liquid storage area is made of reaction tank and recycle tank, the inlet pipeline of this disturbance pump is connected with reaction tank, outlet conduit is connected with recycle tank, and several pipelines that have the nozzle at the bottom of the absorption tower are housed in recycle tank, and this pipeline links to each other with this outlet conduit.
Characteristics of the present invention and effect:
The present invention is different from existing Wet technique, not from increasing gas-liquid contact time, increase the gas-liquid attaching space, increasing liquid holdup, but, make gas-liquid at mass transfer field high speed bump, the state that formation gas phase, liquid phase are all disperseed by setting up turbulent mass transfer field, be implemented in the shortest time, minimum space under the minimum liquid-gas ratio, reaches gas-liquid and fully contacts, carry out the high speed mass transfer, improve high dedusting, desulfuration efficiency under the least energy consumption.
In turbulent mass transfer field, the specific area of liquid is compared with big tens of times of the flowing fluid ratio surface area of common spray column, reach same mass-transfer efficiency, its resistance is on the low side or approaching compared with spray column, liquid-gas ratio but reduces greatly, and the mass transfer space also reduces greatly, in existing liquid-gas mass transfer apparatus, its combination property is fitst water, and energy consumption is minimum.
Principal character parts of the present invention are that turbo-supercharging quickens desulfurating dust removing device for flue gas, be contained in the spray column, because design has helix(ribbon type) agitator in the blade central area, after flue gas enters desulfurizer, flue gas is stronger than the rotate effect that flue gas flow rate brought that blade causes with the high speed rotate effect that desulfurization slurry forms in the helix(ribbon type) agitator zone, and destroyed the vacuum funnel that the center forms, improved desulfuration efficiency.After long-time running, if stop up because of operational issue or other reasons cause helix(ribbon type) agitator, also can reach the desulfurized effect and the efficient of other desulfurizers, this just turbo-supercharging quicken the difference and the superior part of flue gas desulfurization and dedusting dress and other desulfurizers.This device can be according to the size of design exhaust gas volumn, settle at least one or more, compare with other devices have the desulfurization dust-removing efficiency height, capacity is big, stream time is long, liquid-gas ratio is little, is fit to advantages such as various desulfurizing agents.
