Device and method for intelligently detecting blockage of bag-type dust collector

Abstract

The device comprises a visual identification module and a detection module, the detection module comprises a transparent cylinder and a colored light ball, the transparent cylinder is embedded into the top surface of an output pipeline, the light ball is located in the transparent cylinder, an opening is formed in the bottom surface of the transparent cylinder, and the light ball is located in the transparent cylinder. The transparent cylinder is communicated with the output pipeline through the opening, the diameter of the opening is smaller than that of the light ball, the visual identification module is used for detecting the state of the colored light ball in the transparent cylinder, and the scanning area of the visual identification module is the part, located on the top face of the output pipeline, of the transparent cylinder. The height of the part, embedded into the output pipeline, of the transparent barrel is larger than the diameter of the small light ball, the small light ball can be made of plastic materials, and the device and the method for intelligently detecting blockage of the bag-type dust collector are used for detecting the actual operation condition of a single bag and detecting whether a pulse electromagnetic valve operates normally or not.

Description

technical field [0001] The invention relates to the technical field of bag filter detection, in particular to a device and a method for intelligently detecting clogging of a bag filter. Background technique [0002] The bag filter is a dry dust removal device commonly used in the production industry. The bag filter is suitable for capturing fine, dry, non-fibrous dust, and has high dust removal efficiency, and is popular. The filter bag of the bag filter is made of textile It is made of filter cloth or non-woven felt, and uses the filtering effect of fiber fabric to filter the gas containing dust. When the gas containing dust enters the bag filter, the dust with large particles and heavy specific gravity will be affected by gravity. When it settles down and falls into the ash hopper, when the gas containing finer dust passes through the filter bag, the fine dust in the gas will be blocked by the filter cloth, so that the gas originally containing dust will be purified, and m...

[0002] The bag filter is a dry dust removal device commonly used in the production industry. The bag filter is suitable for capturing fine, dry, non-fibrous dust and is popular for its high dust removal efficiency. The filter bag of the bag filter is made of textile It is made of filter cloth or non-woven felt, which uses the filtering effect of fiber fabric to filter the gas containing dust. When the gas containing dust enters the bag filter, the dust with large particles and large specific gravity will be affected by gravity. When it settles down and falls into the ash hopper, when the gas containing fine dust passes through the filter bag, the fine dust in the gas will be blocked by the filter cloth, so that the gas originally containing dust will be purified, and most of the bags will be blocked. The reason is that the pulse solenoid valve is damaged, which makes it impossible to spray. After a long time, the dust on the surface of the bag will agglomerate, causing the bag to be blocked. The existing bag filter is passed through the inlet and outlet of the filter. Install a differential pressure transmitter to detect the pressure difference between the front and back of the bag, and to monitor whether the dust collector is in a blocked state, but this method can only judge whether the entire dust collector is blocked, and cannot detect the actual operation of each bag in the dust collector , when a single bag of the dust collector is blocked or the pulse solenoid valve is damaged, the staff cannot deal with it immediately, which may lead to a decrease in the efficiency of the bag dust collector, and in severe cases may lead to failure and environmental accidents. Therefore, a Device capable of detecting the actual operation of a single cloth bag and whether the pulse solenoid valve is normal or not and its detection method
