Description

Exhaust Gas Purifier Exhaust Treatment Environmental Desulfurization System

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
