Offline pulse control the structure and characteristics of the instrument 
 Offline pulse jet bag filter series is a large air volume handling, cleaning effect, high dust removal efficiency, reliable operation, easy maintenance, small footprint large dust removal equipment. By the box, gray bucket, into the wind pipe exports duct stent, filter bag, and injection devices, cinder devices and other components. Bag cage structures according to different working conditions in various forms (octagonal, round, etc.). It can be used in metallurgy, building materials, electricity, chemicals, carbon black, asphalt concrete mixing, dust control and material recovery boilers and other industries. Such precipitator structural features are as follows. (1), the filter sheet type poppet Offline status, advanced cleaning technology, reliable operation. (2) designed into the wind pipe and ash bucket diversion technology to solve the general bag filter is often sub-chamber airflow uneven phenomenon. (3) bag the top of the spring expansion ring type, sealed, maintenance and replacement bag cage standard length of 6m, but also required the growth of 1 ~ 2m. (4) dust collector control can be advanced program-controlled device with differential pressure, timing, manual three control off valve, pulse valve, cinder valve to achieve a comprehensive system of control. 
 Pulse controller outputs a signal duration of said pulse width. Adjustable in the range of 0.03-0.2s. Output time of the distance between the two signals, said pulse distance; 1-30S range is adjustable. Output signal to complete a cycle of demand, said pulse period. Adjustable within the range of 1-30min. The control device in accordance with the cleaning request to adjust the pulse distance and pulse width, the purposes of regular cleaning of the dust collector. 
 Pulse controller can be divided into a control device of the pneumatic pulse and electric pulse controller. Pneumatic pulse controller the air clean and crunch as the energy source, output pneumatic pulse signal, instead of supporting the use of a pneumatic valve, pulse valve; electric pulse controller to 220V AC power supply as an energy source, the output electric pulse signal, instead of supporting the use of electromagnetic valve, pulse valve or electromagnetic pulse valve. Pulse control instrument are the technical parameters of the show. Commonly used in engineering is the controller of the electric pulse. 
 Programmable logic controller, due to the use of programmable logic controller to control the pulse cleaning process more accurate and reliable pulse controller to fit the users of the centralized control of the operation state of the request so in engineering design, small pulse jet bag filter with pulse controller control, and medium-sized pulse jet bag filter common with the programmable logic controller. The programmable controller can control the cleaning process, but also control the input ash installation, electric smooth installation and the precipitator temperature, pressure and alarm. Pulse controller majority do not have the cleaning outside the control function.
