Description
Technical Field
The utility model relates to a prevent putting adjusting device, concretely relates to spacing regulation fixing device of wet-type electrostatic precipitator.
Background
The proportion of fine particles is higher in present coal fired boiler flue gas, and wet flue gas desulfurization system is unstable to fine particles's dust collection efficiency, and the large granule liquid drop can only be got rid of to mechanical type defroster, and the desulfurization system of not installing GGH carries the gypsum thick liquid again easily, produces the gypsum rain problem, all can cause the smoke and dust to discharge and exceed standard.
The wet-type electric dust removal technology is widely applied to ultra-low emission reconstruction of coal-fired power plants. The wet electric dust collector is arranged after wet desulphurization, and can effectively remove smoke dust, fog drops and SO carried in the flue gas after wet desulphurization3Acid mist, heavy metal, gypsum slurry and other various pollutantsAnd (5) dyeing the materials. The working environment of the wet electric dust remover is different from that of electric dust removal. Firstly, the existence of water drops in the working flue gas of the wet electric dust collector influences the electrode discharge, and the surface potential barrier is reduced. After the water covers the metal surface, the electrode discharge effect can be effectively changed, so that corona discharge can be generated at low voltage. Secondly, the specific resistance of the dust can be effectively reduced by combining water drops in the wet flue gas with the dust, so that the working state of the wet electric dust collector is more stable; in addition, the wet electric dust collector is cleaned by water without a rapping device, so that secondary dust raising is avoided. The wet type electric dust collector is generally disposed behind the wet desulfurization device for collecting the fine particulate matter PM2.5Acid mist (size of 0.1-0.5 μm), etc., the smoke emission concentration can be less than 5mg/m3And effectively solves the problem of gypsum rain in a wet desulphurization system.
However, wet-type electric dust collectors also have some technical problems to be solved. The cathode system of the vertical tubular wet-type electric dust collector is arranged in a suspension manner. A suspension system at the top of the dust remover provides a load supporting point for the cathode system, and the lower end of the cathode line is pulled by a heavy hammer to keep the cathode line vertical; the lower cathode frame restrains the displacement of each cathode line and the weight in the horizontal direction. But the cathode system can not satisfy the operation requirement only by top suspension, and the cathode system can rock in inside along with operating condition's change, and the cathode system rocks slightly and causes electric field operation parameter to reduce with the volume, and the equipment operation parameter is reduced in the flashover that discharges, still can cause electric field short circuit and puncture when serious and strike sparks. Therefore, the lower end of the cathode system also needs to be fixed in the horizontal direction, and the electrode distance adjustment needs to be carried out in multiple directions during installation, so that the sufficient discharge distance of the cathode fixing device is ensured. Avoid the cathode system to rock during operation, still need simultaneously with equipment body high-pressure insulation, acid-resistant corrosion possesses these several functions simultaneously. Most of the applied wet-type electric dust collectors cannot thoroughly solve the problems, and the technical problems of large fluctuation of operating parameters, low dust collection efficiency, high failure rate and the like exist.
