Embodiment Construction

[0040] like figure 1 As shown, a filter bag breakage detection device for a bag filter, the detection device includes a light source 1, a light transmission mechanism and a light detection mechanism; the light transmission mechanism is used to transmit the light emitted by the light source 1 to the filter bag 6 at the exit of the filter bag; the optical detection mechanism is used to detect the light intensity at the exit of the filter bag 6, and the detected optical signal is sent to the photodetector 3, and the output of the photodetector 3 is provided with a data acquisition and processing module 4 .

[0041] preferred, such as figure 2 As shown, the light transmission mechanism includes a fiber optic beam splitter 2, a conductive fiber 7A and a high temperature resistant fiber optic probe 9; the fiber optic beam splitter 2 is connected to the light source 1 through an optical fiber, and divides the light emitted by the light source 1 into several bundles The light beam em...

Abstract

The invention belongs to the field of environment protection equipment for atmospheric pollution abatement, in particular relates to a filter bag breakage detector for a bag type dust remover. The detector comprises a light source, a light conduction mechanism and a light detection mechanism; the light conduction mechanism is used for conducting light sent by the light source to an outlet of a filter bag; and the light detection mechanism is used for detecting the light intensity at the outlet of the filter bag, and outputting a detected light signal to a photoelectric detector, and the output end of the photoelectric detector is provided with a data acquisition process module. By measuring the intensity of the light signal returned by each filter bag, the detector not only can ensure the position of the broken filter bag, but also can ensure the size of a breakage position, so that a filtration chamber in which the filter bag is arranged can be automatically turned off according to the information, and alarm can be carried out. Therefore, the detector has the characteristics of non-contact, real time, telemetering and the like, and important parts such as the light source and the like can be far away from the high-temperature and high-pressure environment of the dust remover by an optical fiber, so that the environment requirement to a breakage detecting system can be reduced.

Description

technical field [0001] The invention belongs to the field of air pollution control and environmental protection equipment, and in particular relates to a filter bag damage detection device for a bag type dust collector. Background technique [0002] Bag filter is a kind of high-efficiency dust removal equipment, which is widely used in metallurgy, electric power, cement, chemical industry and other industries. The structure of the bag filter is as follows: figure 1 As shown, the air to be dedusted enters the dust collector 5 through the dust collector inlet 8, and is discharged from the dust collector outlet 10 after being dedusted by the filter bag 6 in the dust collector 5. In engineering applications, often due to the damage of individual filter bags, the dust discharged through the outlet 10 of the dust collector increases. Even if the discharge concentration does not exceed the allowable emission concentration requirements, it will cause the overall operating efficienc...
