Description

Hot air blowing device for electrostatic dust collection insulation box

Technical Field

The utility model relates to an electric precipitation insulation can technical field specifically is an electrostatic precipitator insulation can hot-blast device that sweeps.

Background

The function of insulation can lies in insulating the insulating vase of negative pole system in flue gas and surrounding environment. The electric heater is arranged to keep the temperature of the insulating porcelain bottle higher than the frost point by 20-30 ℃ all the time when the insulating porcelain bottle operates, so that the insulating porcelain bottle of the cathode system is not polluted by dust in flue gas, and the insulating porcelain bottle is prevented from dewing due to too low temperature. If the insulating porcelain bottle of the cathode system is polluted or condensed, the insulating porcelain bottle can creep and lose the high-voltage insulating function. In actual use, in the larger closed space of the heat preservation box, a manufacturer simply considers that each porcelain insulator is required to reach the guaranteed temperature, and only one electric heater is arranged on the edge of each porcelain insulator for heating. Although the number of the electric heaters is large (60), the distance from the electric room to the insulation can of the heater cable is long, the number of the intermediate rotation times is large, the uncertainty factor is increased, and the quality reasons of the electric heaters cause that the fault rate of grounding, short circuit and open circuit of the heaters is relatively high. Meanwhile, a manufacturer neglects that the space of the heat insulation box is too large, the whole temperature rise in the box is not obvious even if all heaters are put into operation, and the temperature difference of all areas in the box is extremely unbalanced, so that moisture is more easily attached to parts which are not heated particularly under the humid and hot weather condition in the south. Once a certain insulator is in fault due to the heater, the moisture condensation and the damp are easily caused due to large temperature difference, the creepage breakdown is further realized, and the corresponding electric field is cut off and the operation is stopped. In addition, manufacturers neglect that creepage breakdown faults are easily caused by pollution or dew condensation of insulation pillars which are exposed to sunlight, and no effective heating measures are provided.
