4. adopt two alkaline process to recycle, guarantee desulfurized effect, reduce operating cost.
5. the equipment operational administrative is simple, and is easy to maintenance.
Desulfurizing tower operation principle: impact eddy flow centrifugal spray desulfurizing tower and utilize condensation, coalescence effect to improve arresting efficiency to fine dust, adopt impact and cyclonic action to improve the mixing and the exposure level of aqueous vapor, flue gas more than two kinds is handled mechanism optimum organization in one, has the efficiency of dust collection height, the characteristics that desulfurized effect is good.
The tail gas that need handle is introduced this equipment by tube connector washing chamber, adopt clog-free shower nozzle that cleaning solution is sprayed into, mist is dripped with waste gas to reach capacity and hypersaturated state, the back is by the acceleration and the diffusion of impact tube, steam begins condensation, tiny grit becomes nucleus of condensation, and water vapor condensation makes its outside water membrane that forms to grit.Water droplet in the gas and the grit that is encased by moisture film owing to the speed difference that density varies in size and produces, collide it each other, form thicker condensate.Waste gas after cohesion directly impacts bottom wash liquid, and waste gas is fully contacted with cleaning solution once more.After gas shock bottom liquid level is waited,, enter spray chamber, and in spray chamber, set up potent atomizer, the gas-liquid in the flue gas is fully contacted, thereby remove sulfur in smoke through eddy flow plate guiding.After enter the eddy flow dehydrator, gas is separated fully with liquid.
Because this equipment provides good gas-liquid contact conditions, the SO in the gas
2Absorbed the effective of (desulfurization) by alkali lye, condensation process and eddy flow plate have good dust removal performance to more tiny grit simultaneously, dustshot in the gas is adhered to and removes by water smoke on the eddy flow plate, thereby makes dust and sulfur dioxide in the waste gas reach best purification.
Desulphurization system
1. process system:
Pulverized limestone-NaOH double alkali method desulfurizing technology is mainly by absorbent supplying system, compositions such as desulfurizing tower SO2 adsorption system, flue gas system, circulation depletion cell system.
2. absorbent supplying system:
After this engineering construction was finished, absorbent adopted pulverized limestone fineness requirement 325 orders, and under this fineness, calcium carbonate and Ca/S specific energy remaining in the gypsum access a comparatively desirable value.
The wet type pulping system is simple relatively, and agstone enters stirring pool and enters in the regulating reservoir after stirring, and by being pumped into desulfurizing tower, the buck that desulfurizing tower falls flow back in the circulatory pool, recycles through post precipitation again.
The limestone slurry liquid measure that enters desulfurizing tower is controlled into and out of the sulfur dioxide concentration of flue gas and the pH value of desulfurizing tower according to desulfurizing tower, and pH value is controlled in the scope of 9-10.
3. flue gas system:
The flue gas of drawing from boiler induced-draft fan outlet, through smoke pipe enter adsorption tower, in adsorption tower desulfurizing and purifying, after demister is removed water smoke, draw the attached tube of cigarette through smoke stack emission entering.
Flue gas is after desulfurizing tower purifies, and its performance should be fit to the requirement that boiler load changes, and guarantees that desulfurizer can operate in the 30%-100% load range.
4. gypsum treatment system:
From the calcium plaster that desulfurizing tower is discharged, solid contents is about this engineering of 10%-18%. desulfurated plaster based on comprehensive utilization, and stacks the place separately in an ash reservation.For the ease of the transportation of gypsum, store and utilization, need carry out processed.
5. system operation mode:
When boiler normally moved, its desulphurization system is operation simultaneously also, only allowed flue gas to walk the desulphurization system bypass when special circumstances and failure condition, (flue gas is by the bypass flue) operation under the situation of no desulfurizer of boiler this moment.During normal the operation, desulfurizer is in to move under any operating mode and all can not produces any influence to the boiler unit.
During the desulphurization system operation, the import and export baffle door of desulphurization system is opened.Bypass damper door is closed.The absorption tower underrun makes, and presses the absorption tower characteristic with stoppage in transit one deck nozzle, to adapt to the variation of load.
In the boiler startup process or the desulphurization system off-the-line, when needing maintenance, desulphurization system import and export flapper closure, the bypass damper is opened, the unit flue gas directly enters chimney through air-introduced machine and bypass flue and discharges.
Save and the reasonable use energy:
Be reasonable energy utilization and energy savings, guarantee rationality of technological process from designing, the equipment that each link is adopted all can embody low power consuming and high efficiency, reaches reasonable energy utilization and reclaims the purpose of the energy as far as possible.
1. energy savings:
The optimization system design is optimized configuration to desulfurizer equipment, flue, pipeline, cuts down the consumption of energy:
2. using water wisely:
The desulphurization system water mainly comprises the adsorbent pulping water, the technology supplementing water.Desulphurization system adopts closed cycle to use.
3. the disposal of desulfuration byproduct:
The lime-ash that desulphurization system is produced is that gypsum is that CaSO4,2H2O. current period engineering flue gas desulfur device system generation byproduct desulfurated plaster purity are not less than 80%, is convenient to comprehensive utilization.(can use) for gypsum plate mill and building.
