Now, with the continuous improvement of its national atmospheric emission standards and the growing public awareness of the environment, its bag filter is increasingly occupying a dominant position in the treatment of industrial dust, and it can be effective in the research of its supporting automatic control technology. The promotion of bag-type dust removal technology continues to progress and a large number of indispensable conditions for application.
During the operation of the bag filter, the control requirements of its dust removal process become higher and higher. The entire equipment mainly adopts the informationization and networked control of the baggage to set new requirements for the control of the dust removal system. At the same time, With the continuous development of computer technology, control theory, and network technology, new theories and technologies are emerging, and they are quickly applied to the control of production processes.
Bag-type dust collectors, to a certain extent, require that the main production equipment be equipped with the same level of control equipment, and be unified in management and maintenance. Bag-type dust collectors are far less valued in design, manufacturing, production and maintenance management. Main process equipment. Now that “clean production” is required, production and environmental protection are inseparable, and production equipment must meet the requirements of environmental protection.
The bag filter will always use its simple and rough control method during the control process. The device’s ash control generally adopts its timing control or constant pressure control in a certain degree. The timing of dedusting is mainly in accordance with Its pre-set cleaning period and interval control its cleaning mechanism work, belonging to open-loop control.
The constant pressure difference control of the bag filter is effective to control the cleaning according to the differential pressure at the outlet of the device. When the pressure difference is higher than the upper limit, the cleaning is started. When the lower limit is lower, the cleaning is required to stop the cleaning. There are also two types of control methods used in the process.
