WATER FILM TYPE DEDUST ING& DESULFURIZATION EQUIPMENT
This equipment is mainly composed of the main cylinder, upper note cistern, lower spillway hole, cleaning eye, its working principle is: flue gas into the cylinder, the cylinder is a round cylinder, upper injection water from filter tank into the cylinder, make whole cylinder wall to form a layer of 3-5 cm of water film flows from top and bottom, flue gas from the cylinder bottom tangential to and in the cylinder body rotation, dust gas under the action of centrifugal force, keeping water film and the cylinder body wall friction, such dust gas membrane wet by water, dust particles with flow to the bottom of the dust catcher, walk from spillway hole row, and is equipped with water seal in the bottom of the barrel back to prevent gas leakage from the bottom and a cleaning eye for the bottom of the barrel clean up.After cleaning wastewater by the overflow hole at the bottom of the discharge into the sedimentation tank, neutralization precipitation, circulation use. After purification, the gas through the induced draft fan, complete the whole process. When adding desulfurizer in the pool, because the air in the desulfurization tower for longer than three seconds, such gas liquid have longer exposure time, is beneficial to the reaction of sulfur dioxide and desulfurizer, requirements in the sedimentation tank PH value reached around 9.
This equipment and main chemical reactions in water film dust desulfurization equipment: (with NaOH and Na2CO3 double alkali as absorbent to show)
NaOH + SO2 + O2 - NaSO4 + H2O
NaOH + and SO2 Na2SO3 + H2O
NaHSO3 + Ca (OH) 2 - CaSO3 + Na2SO3 + NaOH
Na2SO3 + Ca (OH) 2 - > CaSO3 + NaOH
CaSO3 + O2 - CaSO4
1. The characteristics of the equipment
Combined the characteristics of the water film dust remover, low cost, convenient installation, corrosion resistance, abrasion resistance, durability, high and stable performance collection coefficient, strong adaptability, can be used for a variety of industrial boiler dust removal and desulfurization and dust places, stable operation, simple maintenance. Support the ideal boiler accessories.
1.1. Using natural granite, after machining into circular plate, the overall structure of the smooth level off. Corrosion resistance, wear resistance, high temperature resistant characteristics.
1.2. Each section 1 meter by using ontology, outsourcing steel plate, with each section excuse concave and convex shape juncture, when installation using acid-resistant rubber coated in seam connection, to ensure that the joint is not leaking.
1.3. Import and export are provided with flange and flange size, installation flange joint with asbestos rope caulking, beware of air leakage, influence dedusting effect.
2. The performance and parameters
Dust removal efficiency: > 98%
The desulfurization efficiency: > 80%
Import smoke speed: 16-20 m/s
Mmh2o cylinder resistance: 70-70
Drops of precipitator cylinder rising smoke speed: 3.5 to 5.5 m/s
The overflow groove static pressure: 2-5 mmh2o
Dust removal after the flue gas temperature: 50-80 ºC
Dust emission concentration < 200 mg/m after
SO2 emission concentration < 800 mg/m after
Salinger, blackness < 1 level
3. The installation
3.1. Composite water film dust remover should be designed according to choose type and installation site geology dust catcher foundation, foundation must level off, the error is less than 5 mm.
3.2. Filter water supply system, air ducts, sedimentation tank and other ancillary facilities must be designed at the time of installation as a whole.
3.3. The overflow tank parts is the key parts, must be installed correctly. Irrigation water level elevation difference after leveling should < 2 mm.
4. Operation maintenance
4.1. Should add fresh water in the pool before operation, and water supply to the filter to the overflow mouth water overflow, check whether the quality is conform to the requirements, smooth water supply system and supply of mouth water not leak tight.
4.2. Before operation, should be induced draft fan, and water supply to the water supply system, the furnace, should stop to supply water to the water system before closing induced draft fan. , in the operation of the cylinder is absolutely not allowed without water, regularly check the overflow tank was clear, want to often observed smoke temperature and flue gas resistance at the same time.
4.3. Regular cleaning are deposited in the sedimentation tank, try to keep the purity of the circulating water.
4.4. For the desulfurization efficiency is above 80%, must be quantitative add lye in circulating cistern regularly, keep circulating water PH value of the above 9, containing acidic waste water in the tank and the alkaline neutralization precipitation can be recycled after filtration.
4.5. Stop for a long time, such as filter operation or runtime upper trough appear flashing phenomenon, should be to provide clean water to sink, such as tap water scour for an hour or so, in order to remove dust in the sink.
5. The pump selection
Suggested use: abrasion resistant submerged pump
