Pulse bag type dust collector consists of frame, box, filter bag, dust cleaning device and compressed air device, differential pressure device and electric control device group.
Installation of the box: the boxes are manufactured from sheet plates, and the box plates are assembled into large pieces on the ground according to the box diagram. After assembly, the flanges of each box are corrected, and the boxes are welded after meeting the requirements. Forming. Hang all assembled boxes on the ash hopper and correct the plane of the flange on the middle box after positioning. The inside of the middle box is all sealed and continuously welded. Due to the intersection of the structural welds, the inaccessible welds have openings to seal the tight welds. Special attention must be paid. All tight welding seams are inspected with kerosene leakage inspection method. Repair welding is performed on leaky areas. There is no leakage at the on-site tight welding seams.
Filter bag, bag cage and blow pipe installation
1. Check the perimeter of the hole of the flower plate, it should be smooth, without burrs, and without deformation.
2. After the filter bag and the bag cage are installed and adjusted, install the spray pipe. After adjusting the center of the spray hole of the spray pipe to the center of the filter bag, fix and tighten the back end of the spray pipe. And meet the company's relevant installation requirements.
3． Filter bags and bag cages should be used for all welding or connection parts of the dust collector before installation, including the trial installation of the upper cover. The interior of the dust collector should be cleaned and rectified in a timely manner. Install the filter bag, otherwise the consequences will be borne by the installation unit, and the installation method of the filter bag and the bag cage will be performed by the technicians on site.
After all the installation work of the surface paint dust collector is completed, the surface of all exposed steel structures is brushed with alkyd enamel (or according to the technical agreement) twice to reach the specified thickness. Red welding rust-proof paint should be applied to the welding site.
