Summary of the invention
Goal of the invention of the present utility model is to provide an a kind of belt electrostatic precipitator and an insulation chapelet thereof that has efficient height, reliability height and be suitable for being applied to the anti-condensation structure of belt electrostatic precipitator application, and for example belt is transported the belt electrostatic precipitator of transmission etc.The belt electrostatic precipitator technical scheme that the utility model provides, its major technique content is: a kind of belt electrostatic precipitator, the discharge electrode corona wire that comprises the channel-type collecting plate that is arranged at transport tape top, high pressure input cable, sets up by an insulation chapelet, an insulation chapelet probes into the dedusting space and sets up the discharge electrode corona wire, insulation chapelet upper end is provided with the hot blast casing, and collecting plate is the hot blast that communicates with the hot blast casing gap of shoving in an insulation chapelet probe hole.
On the basis of above-mentioned overall technical architecture, for avoiding discharge electrode corona wire dewfall and adhering to dust, further solve technical problem creepage and the raising security, an edge insulation chapelet axis is provided with the axis hole that wears high pressure input cable, and the upper and lower end that props up chapelet in insulation is respectively equipped with cable sealing device.
The utility model also provides a kind of insulation as above-mentioned belt electrostatic precipitator vitals to prop up the chapelet technical scheme, and this insulation chapelet is provided with the axis hole that wears high pressure input cable along its axis.
The disclosed belt electrostatic precipitator of the utility model technical scheme, directly utilize the hot blast resource to flow fast and be covered in insulation and support sub-surface, the insulation that is exposed to the dedusting space be can drive away comprehensively and the dew of sub-surface and the dust that adheres to supported, can also effectively separate at any time and will support the dewfall steam and the dust of sub-surface, thereby effectively solve dewfall and the creepage technical barrier of high pressure near being attached to insulation.In addition, an insulation chapelet adopts high pressure input Seal of Cables to wear structure, has also changed the dewfall of high pressure input cable and the creepage present situation of dust, further improves the security and the reliability of dedusting work.
