Abstract
The utility model discloses a flue gas desulphurization device for float valve foam sieve plates. The flue gas desulphurization device comprises a desulphurization tower body, and is characterized in that: two or more layers of float valve foam sieve plates are arranged in the desulphurization tower body; each float valve foam sieve plate is provided with an overflow weir; the surface of each float valve foam sieve plate is provided with uniformly-distributed valve holes; and a gas guide valve plate is arranged on each valve hole. By adopting the flue gas desulphurization device, high desulphurization and dust removal efficiencies are realized, the catching efficiency of dust particles of 0.1-3 mum can be up to 99 percent, the total dust removing efficiency can be up to 99.5 percent, the desulphurization efficiency can over 96 percent, and the synchronous running rate of desulphurization and dust removal equipment along with a stove kiln is 100 percent.
Description
Technical field
The utility model relates to a kind of the discharging the flue gas from stove and removes dust and SO
2Device.
Technical background
The Energy Mix of China is based on coal, and its consumption figure accounts for about 70% of primary energy aggregate consumption, and this situation can not change in considerable time from now on.Coal directly burning discharges a large amount of dust and SO
2, cause air environmental pollution, heavy damage existent environment of people, environmental protection work is the important assurance that China implements the strategy of sustainable development.So, strengthen dust and SO
2The control dynamics just seem very urgent and necessary.Along with current environmental protection to the discharging flue gas in dust and SO
2Improving constantly of requiring of control, the disposal ability of original stove flue gas wet desulfurization dust-removing device, 90% desulfuration efficiency and 98% efficiency of dust collection have been difficult to reach user and current environmental requirement, cause the synchronous operation rate of equipment and stove not reach 100%.
Summary of the invention
The purpose of this utility model is to provide a kind of desulfurization dust-removing efficiency height, guarantees the float valve foam sieve plate flue gas desulfur device of desulfurating dust-removing equipment and stove synchronous operation.
The technical solution adopted in the utility model is: a kind of float valve foam sieve plate flue gas desulfur device, comprise the desulfurization tower body, it is characterized in that: in the desulfurization tower body, be provided with the float valve foam sieve plate more than 2 layers or 2 layers, on float valve foam sieve plate, downflow weir is set, have equally distributed valve opening on float valve foam sieve plate surface, the gas channeling valve block is housed on each valve opening.
Described valve opening is by rounded projections arranged.
Downflow weir on the float valve foam sieve plate of the present utility model makes can keep certain thickness alkaline foam on the plate, the sulfur-containing smoke gas that rises is dispersed into tiny plume by valve opening, bubbling and going out in the liquid layer onboard, forming froth bed makes close contact between gas-liquid and carries out mass transfer, the dedusting liquid of sulfur-containing smoke gas of Shang Shenging and lateral flow forms cross-flow simultaneously, make this device have bigger operating flexibility, reach 100% with boiler synchronous operation rate.
The utility model desulfurization dust-removing efficiency height, its grit efficient of catching 0.1 μ m～3 μ m can reach 99%, and total efficiency of dust collection can reach 99.5%, and desulfuration efficiency can reach more than 96%, guarantees desulfurating dust-removing equipment and stove synchronous operation rate 100%.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is a valve opening enlarged drawing of the present utility model;
Among the figure, the 1st, desulfurization tower body, the 2nd, float valve foam sieve plate, the 3rd, alkaline froth bed, the 4th, desulfurization and dedusting liquid, the 5th, downflow weir, the 6th, valve opening, the 7th, float valve foam sieve plate plate body, the 8th, gas channeling valve block.
The specific embodiment
The utility model is described in further detail with the specific embodiment with reference to the accompanying drawings below:
From Fig. 1, Fig. 2 as can be known, the utility model float valve foam sieve plate flue gas desulfur device comprises desulfurization tower body 1, in the desulfurization tower body, be provided with float valve foam sieve plate 2, on float valve foam sieve plate, downflow weir 5 is set, have many uniform valve openings on float valve foam sieve plate surface by rounded projections arranged, the gas channeling valve block is housed on each valve opening, and the quantity that valve opening is opened on the float valve foam sieve plate and the opening width of valve block can change with the variation of boiler smoke amount size.Wherein the number of plies of float valve foam sieve plate 2 is required to determine by desulfurization, is generally more than 2 layers or 2 layers.
The course of work: earlier from last adding desulfurization and dedusting liquid, desulfurization and dedusting liquid then is horizontally through float valve foam sieve plate, downflow weir on the float valve foam sieve plate makes can keep certain thickness alkaline froth bed on the plate, sulfur-containing smoke gas feeds from bottom to top, be dispersed into tiny plume through valve opening, bubbling and going out in the liquid layer on the slave plate, the alkaline froth bed of formation make between gas-liquid contact closely and carry out mass transfer, the desulfurization and dedusting liquid of sulfur-containing smoke gas of Shang Shenging and lateral flow formation cross-flow like this.
