Description
Technical Field
The utility model relates to auxiliary equipment for installing anode plates of a dry electric dust collector of a converter, and belongs to the technical field of installation of equipment of dry electric dust collectors of converters.
Background
The existing converter dry electric dust remover equipment is designed for multiple electric fields, the number of anode rows and cathode frames is large, the area is large, and the anode rows and the cathode frames are assembled in advance before the furnace shutdown in general for improving the installation efficiency. Firstly, prefabricating a temporary assembly platform, assembling each anode plate by utilizing the assembly platform, and placing the assembled anode rows on an anode row storage rack prefabricated in advance for ensuring flatness to be used when waiting for installation; and then assembling the cathode frames by using an assembling platform, and sequentially placing the cathode frames on a cathode frame storage rack according to the installation sequence after assembling.
Each 1 row of anode plates of the electric dust collector consists of a hanging beam 11, anode plates 12, a vibrating rod 13, a guide rod 14 and other accessories, as shown in figure 3. Generally, each dust remover consists of 4 electric fields, namely a first electric field, a second electric field, a third electric field and a fourth electric field, taking the electric dust remover with the embodiment phi of 10.8 as an example, each electric field is provided with 23 anode plate rows and 22 cathode frames, the number is large, the size is large, the installation difficulty is high, the thickness of the anode plate is between 1 mm and 2mm, and the anode plate is easy to deform, so that the selection of proper installation equipment and installation method is very important.
The electric field internal structural members of the electric dust collector are staggered by anode rows 15 and cathode frames 16, 1 row of anode plates, 1 row of cathode frames and 1 row of cathode plates, and are staggered as shown in figures 4 and 5.
The installation sequence of the plate line is that the anode row is firstly installed, the anode row is sequentially hoisted row by row and placed at the ring beam positioning plate, then the cathode frame is sequentially hoisted, bound and suspended with the adjacent anode row, and the cathode frame is positioned after the subsequent cathode frame is installed. Taking the example of an electric precipitator with the embodiment phi 10.8 as an example, a conventional installation process is shown in fig. 6 (existing installation method). Firstly, vibrating rods at two ends of an anode row of a front cutting part of the anode plate are hoisted, then hoisted row by row, and directly placed at a ring beam positioning plate. According to the method, only 3 rows of anode rows on two sides of an electric field can be completely hoisted, the rest 17 rows of anode rows cannot be normally hoisted into the electric field due to longer pole plate vibrating rods, and the vibrating rods at two ends of the anode rows need to be cut off by about 800mm, so that the electric field can be hoisted in place. After all anode rows are lifted, the rapping rods which are welded and cut are required to be restored, and the sharp points of the welding openings are polished to prevent discharge, and meanwhile, the strength of the spliced part is greatly reduced. By adopting a conventional installation method, under the condition that the spliced rapping rod is periodically rapped by a rapping hammer, the spliced rapping rod is often broken at a spliced joint, the broken part can fall to an ash scraping device at the bottom of an electric field and even fall into a fine ash scraping machine, so that a scraper of the ash scraping device or a chain of the scraping machine is blocked and deformed, an electric dust collection and transportation system cannot normally operate, more than 80% of unscheduled shutdown of an electric dust collector is counted as the shaking rod waistband after the splicing falls off, the blockage of the fan scraping and the fine ash scraping machine is caused, the ash scraping and transportation system is influenced, the fault shutdown is caused, and more than 70% of the workload of each overhaul is reinforced and welded with the shaking rod waistband and the rapping anvil thereof; in addition, sometimes the broken part can overlap joint on the adjacent discharge electrode frame, so that the electric field short circuit can not run, and the integral dust removal effect of the electric dust remover can be influenced, and the emission of flue gas particles of the diffusing tower exceeds the standard, so that the normal production of the converter is seriously restricted.
Obviously, in the existing installation method, the waistband of the anode rapping rod needs to be cut, the subsequent splicing and polishing amount is large, the labor intensity of operators is increased, the overhaul and maintenance treatment intensity is also large, the failure rate of the rapping rod in the later operation is high, and great equipment hidden trouble is left for the subsequent operation.
