Because the heat insulation box is positioned at the top of the electric dust removal, and the high-dust-content flue gas after the boiler is combusted passes through the lower part of the heat insulation box (as shown in figure 3), the operation temperature in the heat insulation box is not lower than 95 ℃; however, after the unit is shut down, the dry insulators are very easy to absorb moisture under the normal temperature environment, so that the insulation performance is reduced, and the electric precipitation operation is influenced, so that the traditional scheme is that each insulator is additionally provided with an electric heating pipe 5 of 1.5kW, meanwhile, manual cleaning is required to be carried out regularly, high-temperature dehumidification is achieved through electric heating, the insulation performance of the insulators is ensured, and flashover does not occur. If the insulator has flashover in the running of the unit, the electric dust removal is stopped from running, so that the dust emission of a coal-fired power plant exceeds the standard and the ecological environment is influenced.
Chinese patent publication No. CN109647626A discloses a new insulator incubator, which comprises an incubator body, wherein insulators are fixedly mounted at the bottom of the incubator body, and electric heaters are fixed around the insulators. In order to ensure that the interior of the novel insulator is always in the best working environment, 1-3 insulator electric heaters are arranged around each insulator, and a corresponding power supply connecting channel is also configured to supply power to devices in the insulation box. The novel insulator insulation can still adopts the conventional method of electric heating in order to ensure the optimal working environment.
