Intelligent alarm bag type dust removing device

Abstract

The invention provides an intelligent alarm bag type dust removing device, which device comprises an upper box body, a pattern plate, a middle box body, a cloth bag, a bag cage, a lower box body, a signal line, a PLC control cabinet and a DCS system, wherein a bag cage cap is arranged at the top of the bag cage, the bag cage is longitudinally provided with longitudinal ribs and is transversely provided with reinforcing rings, and a blowing protection device and a cloth bag performance monitoring system are arranged at the upper portion of the bag cage. According to the invention, by arrangingthe blowing protection device, the cloth bag can be protected from being damaged due to the improper installation of the blowing device; by arranging the cloth bag performance monitoring system in thecavity of the double-layer blowing protection device, laser with a certain intensity is emitted through the laser emitting device, if the cloth bag is damaged, dust penetrates through the cloth bag to cause the dust concentration in the cloth bag to exceed the standard, the intensity of the laser reaching the receiver is weakened due to the scattering effect of the dust, and the signal is transmitted to the PLC control cabinet and the DCS system after being processed by the signal processor; and if the cloth bag is damaged in the operation process of the dust removing device, the damaged cloth bag can be directly positioned, the alarm is given out, and the operator can immediately determine the position of the damaged cloth bag in the DCS system and replace the damaged cloth bag.

Description

technical field [0001] The invention relates to a bag type dust collector, in particular to an intelligent alarm dust collector, which belongs to the field of environmental protection equipment. Background technique [0002] In industrial production, a large amount of waste gas mixed with solid particles and air will be produced. If this waste gas is discharged directly into the atmosphere, it will pollute the environment and cause harm to the human body. With the severe environmental protection situation in recent years, the environmental protection standards have become increasingly strict, and the requirements for the emission of dust particles have become higher and higher. Traditional dust removal equipment includes cyclone dust collectors, wet dust collectors, filter layer dust collectors, bag dust collectors, etc. The type dust collector has a simple structure and is easy to use. It is more and more widely used in industrial tail gas treatment, powder recovery and oth...

AI Technical Summary

Problems solved by technology

During the use of the bag filter, it is inevitable that the bag will be damaged, resulting in the penetration of dust particles and excessive dust emissions

The bag filter is airtight during operation, and the damaged bag cannot be found in time. When the discharge of dust particles exceeds the standard, the production can only be stopped, and the bag in each chamber of the dust collector should be checked. However, since the bag is suspended and installed on the dust collector , It is a waste of manpower and material resources to remove each cloth bag for inspection, and most of the time it is necessary to replace the entire batch of cloth bags, resulting in waste of resources
