LCMD pulse bag filter product introduction
Boiler bag dust collector is a new type of high-efficiency long bag dust collector developed by our company's technical staff with reference to advanced dust removal technology at home and abroad. It is widely used in boilers, flue gas dust removal and material recovery, dust control in power, metallurgy, building materials, chemical industry . It is a large-scale dust removal equipment with large air volume, good dust removal effect, high dust removal efficiency, small footprint, stable operation, reliable performance and convenient maintenance. The product adopts modular production and stable quality. It has been successfully applied in power, cement, steel and other industries, and can be widely used in metallurgy, casting, power, building materials, mining, chemical industry and other industries.
In view of the dust removal technology of coal-fired boiler flue gas at home and abroad and the current status of supporting equipment for dust collectors, after extensive analysis, on the basis of the mature technology of LCMD pulse bag filter, we have added a series of protection and detection systems, complete design Out of the boiler bag filter, and has been used and tested on many projects.
The company's 40-ton boiler bag dust collector has applied many proprietary technologies, which have been recognized by various design institutes and experts and verified by practice. Mainly include: high-efficiency pulse injection technology: the reasonable selection of imported new low-resistance, high-efficiency, long-life diaphragm electromagnetic pulse valve, plus the unique design and processing method of the injection tube, so that the dust removal method of the bag filter has been thoroughly change.
1. High-temperature resistant filter material application technology: combined with the characteristics of China's coal-fired boiler flue gas, PPS filter material with high cost performance is used, and the fiber is treated with PTFE membrane, which solves the high temperature of boiler flue gas and ordinary filter material The problem of common filter material's short service life also takes into account the performance-price ratio of the filter material.
2. Offline maintenance technology: the application of the new poppet valve technology realizes the non-stop maintenance function of the dust collector (offline and online dust cleaning methods can be arbitrarily selected). The protection device of the poppet valve avoids the dust collector failure caused by the poppet valve problem, thus ensuring that the operation of the boiler will not be affected due to the dust collector.
3. Dust collector protection technology: the use of on-line detection equipment such as internal bypass system, pre-spraying device, temperature and humidity measurement, etc. solves the problem of protection of the dust collector when the boiler is fueled and assisted in combustion and the boiler fails.
4. Detection and monitoring technology: According to the characteristics of the boiler dust collector, advanced online detection and monitoring equipment such as flue gas temperature, humidity, dust collector operating pressure detection, material level detection, and operation equipment fault detection are installed to complete the bag dust collector. All the functions of measurement, monitoring, control, alarm, protection and interlocking can monitor the operation of the dust collector at any time.
5. PLC programmable controller technology: PLC programmable controller provided by SIEMENS is used for control, with a communication interface with the system DCS, which can realize manual / automatic control of the bag dust collector.
6. Resistance control of equipment: Through a series of unique considerations in equipment design, the overall resistance of the equipment is ensured to be safe and reliable from both aspects of equipment structure and filter material.
The use of the above series of advanced technologies ensures that the dust collectors produced by our company have first-class technology and excellent price-performance ratio.
