Bag-type dust collectors were used earlier in foreign thermal power plants. In the early 1980s, many manufacturers came to China to introduce the application of bag-type dust collectors in thermal power plants. The United States, Canada, Australia, Germany, the United Kingdom and other European countries All factories use bag dust collectors, with a dust removal efficiency of 99%. Above 9%, the bag dust removal equipment of Dongguan Bag Dust Removal Equipment Factory has a very good dust removal effect.
Bag type dust collectors of Dongguan Bag-type Dedusting Equipment Factory are widely used in mining, cement, metallurgical steel, grain, machinery and other industries. It is only used for single bag type dust collectors in coal transportation systems and pneumatic dust removal in power industry thermal power plants.
Bag dust collectors have not been widely used in dust removal at the tail of boilers in power plants. Hohhot No. 6 Power Plant has only recently been used. ..... 70t / h boiler, Tianjin Development Zone. 5 ...... Heat source plant 75t / h boiler, Zhangjiagang Free Trade Zone thermal power plant 130t / h boiler, Inner Mongolia Chifeng Longfu Power Plant 75t / h boiler, etc. Dust removal has achieved a good dust removal effect.
Among them, the Hohhot power plant uses Zhungeer coal. The content of SiO 2 and al2o 3 is too high, and the content of K2O and Na2O is too small. It is difficult to use an electrostatic precipitator. The operating efficiency of the electrostatic precipitator used is far lower than the design efficiency, which seriously exceeds the standard. In 2001, two 200 MW units were expanded. After discussions with experts, it was decided to use a domestic large-scale pulse bag filter. The first 200 MW unit was put into production in early 2002, and the bag filter was operating well.
In the process of introducing and digesting foreign bag filter technology, through the GEF project, we introduced the design and manufacturing technology of coal-fired boiler bag filter for EEC Environmental Technology Company, which has been North America's leading air pollution control system for more than 50 years. It fills the gap in the successful application of bag dust collectors in the domestic boiler industry and can replace imports. It adopts a unique structure of a boiler long bag pulse dust collector and an advanced dust collector to guide the air.
Dongguan Cloth Bag Dedusting Equipment Factory uses an advanced three-state dust removal device. The normal service life of the filter bag is 3 years, and the smoke and dust emission concentration is generally less than 50mg / nm3 or even lower. Tianjin Development Zone. 5 heat source plant, Zhangjiagang Bonded Zone Thermal Power Plant and Inner Mongolia Chifeng Longfu Power Plant. The improved off-line dust removal pulse bag filter has a good dust removal effect.
With China's increasing emphasis on environmental protection, GB 13223-2003 "Emission Standards for Air Pollutants in Thermal Power Plants" has been issued by the State Environmental Protection Administration. The permitted emission concentration of the third phase of smoke and dust has been reduced from 200 mg / nm3 to 50 mg / nm3. Some coal types use electrostatic precipitators that do not meet the emission standard requirements and require bag dust collectors. It is expected that more and more bag dust collectors will be used in thermal power plants in the future, with broad application prospects.
Advantages of bag dust collector in Dongguan bag dust removal equipment factory
● Dust removal efficiency is up to 99%. 9% or more;
● Less auxiliary equipment, less investment and low technical requirements;
● Capable of capturing dust with high specific resistance and difficult to recover by electrostatic dust removal;
● The bag type dust collector has stable and reliable performance, strong adaptability to load changes, and simple operation and management. It is particularly suitable for capturing small dry dust. The collected dry dust is easy to handle and recycle;
● A new theory of dust removal applicable to the entire production process, reducing total emissions.
● Bag type dust collector is suitable for purifying dusty gas containing explosion danger or spark.
