Damaged cloth bag positioning method for bag-type dust collector

Abstract

The invention relates to a damaged cloth bag positioning method for a bag-type dust collector, a cloth bag chamber in the bag-type dust collector is provided with a layer of cloth bag array composed of a plurality of cloth bags, and the damaged cloth bag positioning method comprises the following steps: S1, carrying out equipment preparation: arranging a plurality of cameras above the cloth bag array, and arranging a set of light source above the side edge of the cloth bag array; S2, establishing a world coordinate system, numbering all the cloth bags, and determining the position coordinates of each cloth bag in the world coordinate system; S3, turning on the light source and the cameras, and transmitting an image shot by each camera to an image processing system; S4, carrying out image processing: calibrating the cameras, and calibrating all images shot by the cameras into a world coordinate system; and S5, identifying the light spot in the image shot by the camera by adopting an image two-dimensional edge identification technology, determining the coordinate of the light spot in the world coordinate system, and determining the serial number and the position of the damaged cloth bag in combination with the position coordinate of the cloth bag in the world coordinate system.

Description

technical field [0001] The invention relates to the field of flue gas purification, in particular to a method for locating a damaged bag used in a bag filter. Background technique [0002] 4. Sintering flue gas purification adopts semi-dry circulating fluidized bed process, the dust carried in the flue gas is often filtered and captured by the bag filter, and then returned to the system for reuse. Reference attached figure 2 , the baghouse 1 in the baghouse can be divided into two layers, a large number of bags 21 are arranged on the top of the lower layer, and the bags 21 are usually arranged in the form of multiple concentric rings to form a circular bag array 2, refer to the attached image 3 And attached Figure 4 shown.

Problems solved by technology

[0003] During the bag dust removal, the bag is in a swinging state under the action of the horizontal push of the flue gas and the top rotating injection. At the same time, the bag is continuously stretched and shrunk under the action of the blowing, causing the bag and the bag cage to wear and tear, making the bag easy to break. Therefore, it is necessary to Find the damaged cloth bag and seal or replace it

At present, the method of shutting down and then manual operation is often used. Due to the large number of bags, the work efficiency is low, and it is easy to miss the phenomenon, and the environment in the bag room is bad, which is not conducive to manual operation.
