Summary of the invention
The object of the invention is to overcome existing amine process flue gas desulfurization device complex process, floor space is large, and the deficiency that operating cost is high, the invention provides a kind of renewable organic amine circulation desulfurization purifying column of integral type.
A kind of renewable organic amine circulation desulfurization purifying column, it is characterized in that, it comprises a tower body made by fiberglass; Tower chamber upper space is set to spray district, and spray equipment and demister are arranged in spray top, district, and tower chamber end face arranges exhanst gas outlet, and tower body sidewall arranges gas approach, fresh water (FW) import and organic amine charge door near spray district bottom position; In tower chamber, bottom is slurries district, and slurries district dividing plate is divided into cold-zone and hot-zone, and 60 DEG C of high temperature slurries after washing flue gas are received in hot-zone, and 43 DEG C of low temperature slurries after heat exchange are received in cold-zone; Wherein hot-zone is communicated with completely with spray district, and top, cold-zone is completely closed by cover plate; Arrange the outlet of hot serum recycle in the position, hot-zone of tower body sidewall, cold-zone arranges cold serum recycle import, and the outlet of hot serum recycle is successively by slurry circulating pump and heat exchanger and cold serum recycle inlet communication; Arrange cold serum outlet at the cold spots of tower body sidewall, cold serum outlet is communicated with feeding spraying pump, and feeding spraying pump is communicated with spray equipment again; The position, hot-zone of tower body sidewall is also provided with the bleeder valve for discharging rich solution, and the cold spots of tower body sidewall is also provided with the refluxing opening for lean solution backflow.
Be set to conical bottom respectively at the bottom of the tower of purifying column cold-zone and hot-zone, conical bottom all arranges evacuation port; Both overcome and offered at Ta Bishang the disadvantage that evacuation port can not be emptied completely slurries in tower, overcome the problem that dust is easily piled up simultaneously.
Above-mentioned smoke inlet, exhanst gas outlet and all slurries are imported and exported parts and are fiberglass making, and adopt Flange joint; Subregion dividing plate in tower, cover plate spraying layer brace summer, demister brace summer are glass steel material.
Above-mentioned tower body can according to the difference of temperature range, and tower body is divided into some joints by the change with tower height degree, and every root section carries out type selecting according to temperature requirement to fiber glass resin, and selects tower wall thickness; Flange joint is adopted between joint and joint.
Organic amine circulation desulfurization technology principle of the present invention is as follows:
In aqueous, the SO of dissolving
2meeting generating polynomial (1), the reversible hydration shown in (2) and ionization process:
In water, add organic amine can increase SO
2meltage.Hydrogen ion in organic amine and water reacts, and form amine salt, (1), (2) reaction equation react to the right, increase SO
2meltage;
Reaction (3) illustrates SO
2concentration increase, balance moves right, and is conducive to organic amine liquid and removes SO in flue gas
2gas.
Renewable organic amine circulation desulfurization technology of the present invention is as follows:
1, after purifying column of the present invention is installed, from the import of purifying column fresh water (FW) and organic amine charge door, fresh water (FW) and the organic amine of additional proportion is first distinguished; Fresh water (FW) and organic amine become mixed liquor in purifying column hot-zone, start slurry circulating pump and make mixed serum enter the storage of purifying column cold-zone, store a certain amount of rear startup feeding spraying pump, make mixed serum start spray;
2, connect flue gas, first flue gas enters purifying column spray district, the mixed serum water counter current contacting of flue gas and spray, the heat in flue gas and SO
2at spray, district is absorbed by the mixed serum sprayed, and the flue gas after cooling and purifying is discharged from purifying column top exhanst gas outlet;
3, SO is absorbed
2after the mixed serum of about 60 DEG C become containing SO
2rich solution, and fall to concentrating on purifying column hot-zone, then enter heat exchanger after slurry circulating pump is constantly extracted out and pressurizeed, be down to volatilization temperature less than 43 DEG C through heat exchange, enter purifying column cold-zone after cooling and store; The spray equipment of rich solution again in feeding spraying pump forced feed purifying column that purifying column cold-zone stores, thus realize the circulation of rich solution shower water, rich solution repeats the SO in type absorption purification tower in flue gas in the circulating cycle
2, as SO in rich solution
2when reaching finite concentration, discharge from bleeder valve; The dust of simultaneously stability, in hot-zone meeting natural subsidence, is regularly discharged at the bottom of tower.
4, the rich solution that bleeder valve is discharged enters regeneration treatment process, SO in rich solution in regeneration treatment process
2be recovered, become the lean solution containing organic amine, got back to the cold-zone of purifying column containing the lean solution of organic amine by refluxing opening, thus make organic amine obtain recycling utilization.
Good effect of the present invention is:
1, this tower is mainly applicable to amine process flue gas desulfurization technique, and amine process flue gas desulfurization technique is a kind of regenerative flue gas desulfurization technique, and have desulfuration efficiency high, absorbent is renewable, SO
2can recycle, not produce the advantages such as secondary pollution; The SO reclaimed
2, can be directly used in and manufacture high-quality industrial sulphuric acid, not need to consume sulphur or troilite, do not need separately to add raw material, make the SO in flue gas
2turn waste into wealth, be fully used, both created economic benefit, solve again the situation of atmosphere pollution, economic benefit and social benefit get bumper harvests.
2, this tower is a kind of integrated novel energy-conserving and environment-protective purifier, takes up an area few.Contact rear slurry temperature because the slurries in purifying column and flue gas are reverse and will rise to about 60 DEG C, the requirement of cooled flue gas desulfurization cannot be met, so the design in " cold/heat " twoth district will be divided at the bottom of tower, by constantly absorb, release heat, make slurry temperature maintain organic amine volatilization temperature (45 DEG C) below, effectively can reduce organic amine and escape; Meanwhile, control slurries and be in SO
2optimal absorption temperature range, can improve desulfuration efficiency greatly; The heat exchanged for can be used as the thermal source of follow-up organic amine desorption and regeneration operation.
4, the dust in slurries, in " hot-zone " meeting natural subsidence, has purified loop slurry to a certain extent, has alleviated the live load of heat exchanger, thus reduce system energy consumption.
5, purifying column adopts all-glass fibre reinforced plastic to make.Fiberglass all reaches the traditional handicraft being even better than carbon steel liner in corrosion resistance, heat-resisting quantity, resistance to abrasion, intensity etc., but also has lightweight, and operation maintenance is convenient, the features such as cost is low.Glass steel tower adopts vertical winding technique, and inner liner, strength layer and external protection coating one-shot forming, liner, without longitudinal seam, improves the intensity of goods.
6, SO is reclaimed
2after obtain recycling utilization containing the lean solution of absorbent, thus save operating cost.
