Injection time (pulse width) is generally 0.08 ~ 0.15 sec (seconds). Injection interval (pulse interval) can refer to the following parameters: Air pressure ≥4MPa; filtration velocity V≤1m / min, while the entrance to the gas dust concentration C≤15g / m3 Ningxia baghouse equipment modification, injection interval is 20 ~ 25sec (s); filtration velocity V≤1m / min, while the entrance to the gas dust concentration C≥15g / m3, the injection interval of 10 ~ 20sec (seconds). Monitoring results show that the first eight months, the province's average PM2.5 concentration is still rising year on year; from 13 provincial cities look Ningxia baghouse manufacturers, in addition to achieving fall outside Nantong Ningxia baghouse, and the remaining 12 were in the city to rise . "This results in Ningxia baghouse Which is cheap, Jiangsu, the situation is very serious." This year is the National Air Quality and started working double assessment in the first year, according to the assessment requirements, this year the province's annual average PM2.5 concentration must fall 2%, in order to get passing grade. Ningxia baghouse equipment, Ningxia bag filter, three wins and environmental protection provided by the Environmental Protection Technology Co., Ltd. Henan three wins. Henan three wins Environmental Technology Limited (www.hnsshbkj.com) (www.hnsshbkj.com) strong, credible, in Zhengzhou, Henan Province of dust removal equipment industry has accumulated a large number of loyal customers.
