Bus control method for pulse bag type dust cleaner and device

Abstract

The invention discloses a bus control method for a pulse bag type dust cleaner and a device. The bus control method for a pulse bag type dust cleaner is characterized in that an intelligent control system is used for controlling a dust cleaner through a bus control device arranged between the intelligent control system and the dust cleaner; an external power supply provides working power for the bus control device; a bus cable of the bus control device is connected with the intelligent control system, and the bus control device receives pressure difference measurement signals of the dust cleaner; besides, the bus control device also controls a group of pulse solenoid valves arranged on the dust cleaner. The device of the invention can realize the remote monitoring and control of the dust cleaner, and has favorable extension performance. With the invention, failures of the dust cleaner during operation can be found in time, the operation reliability of the dust cleaner is improved, and the working load of maintenance personnel is also reduced.

Description

technical field [0001] The invention relates to a bus control method and device for a pulse bag type dust collector, belonging to the field of electrical monitoring. Background technique [0002] Pulse bag dust collectors are widely used in electrolytic aluminum plants, carbon plants and alumina plants. These pulse bag dust collectors are generally installed on the top of storage warehouses that are difficult for maintenance personnel to reach, the top of conveyor lines with high steel frame structures, and the outer canopy of factory buildings. on the platform. In the prior art, a simple control method is generally adopted for the control of the pulse bag filter, that is, the pulse controller is directly used to control the pulse soot blowing of the pulse electromagnetic valve on the filter, and at the same time, the working state and efficiency of the filter are measured. The differential pressure signal inside the dust collector is also displayed directly on the spot or ...

AI Technical Summary

Problems solved by technology

Therefore, it is impossible to monitor the status and remotely control the pulse bag filter on a process line during operation, which brings great inconvenience to production and is not conducive to healthy production operation and equipment monitoring and maintenance.

In the prior art, the opening and closing of the pulse solenoid valve in the dust collector is controlled by the pulse level sent by the pulse controller. Level width, so that the action of the pulse solenoid valve is fixed and cannot be changed according to the change of the pressure difference signal that directly reflects the internal pressure of the dust collector. Readout on the Internet, inconvenient for remote monitoring

It cannot be judged in time whether the pulse solenoid valve of the dust collector is blocked, nor can it be judged in time whether the bag inside the dust collector is damaged, which increases the workload of operation and maintenance personnel, and is not conducive to the stable operation and fault detection of the factory's production process
