The precautions for manufacturing and installing bag dust removal equipment are as follows:
Issues to be paid attention to during manufacturing and installation: the processing accuracy of the flower plate, the design and processing of the skeleton should minimize the warpage of the filter bag, the distance between the blow pipe and the flower plate should be accurately calculated, and the shell sealing should be strictly guaranteed during the installation Sex.
Flower plate processing accuracy: At present, the specifications of glass fiber coated filter bags for low-pressure long-bag pulse bag type dust collectors are basically 5m-7m. Due to the bag length, the distance between the bag and the bag and the shell wall plate should ensure that the filter bags do not contact each other. It is always good to have a larger distance, but if the size of the shell is too large, the volume of the shell will be too large, and the investment will increase. However, the processing accuracy of the flower plate will directly affect the verticality of the filter bag and the concentricity of the injection port. The processing requirements mainly include three aspects of quality control:
① The disc hole spacing should be controlled within 1 mm, and CNC plasma cutting should be used to ensure its accuracy.
② The degree of deformation of the flower plate should be controlled within 1/1000, the thickness of the steel plate is required to be at least 6mm, and there must be a certain amount of reinforcement to ensure the rigidity. At the same time, the welding deformation should be controlled within the minimum range during the welding process.
③Smoothness of flower plate: Controlled at 2mm / m2. All these regulations are to ensure that the filter bag reduces collisions.
Attention to the manufacture and installation of bag dust removal equipment: skeleton cages and processing should minimize deformation of filter bags, mainly through several aspects:
The cooperation between the filter bag and the bag filter should be as moderate as possible, not too loose or too tight, and the filter bag should be installed before the bag filter is manufactured in large quantities.
The vertical reinforcing steel skeleton generally uses 20 to 24 high temperature resistant carbon steels, each of which is φ3. The inner ring of the cage is made of 2mm thick and 4 mm high temperature resistant carbon steel rods. The first cage ring from the bottom of the cage and the The distance between the bottom of the cage should be 50 mm. The distance between the second cage ring and the first cage ring should be less than 155 mm. And so on. The last cage ring should be 50 mm from the bottom of the top flange of the cage. . In addition, the processing quality requirements of the bag cage are also very important. During processing, special ring making and spot welding equipment should be used to minimize burrs and maintain verticality.
Note for manufacturing and installation of bag dust removal equipment: The distance between the blower and the panel is accurately calculated: The distance between the blower and the panel is calculated accurately according to the shape and diameter of the nozzle. The axial center deviation between the nozzle and the bag should be controlled within 1 mm Otherwise, eccentricity is likely to occur during blowing, which directly causes local wear of the filter bag and affects the service life of the filter bag.
