Description

A kind of electrostatic precipitator

The utility model relates to a kind of deduster, relates in particular to place's electrostatic precipitator.

In prior art, a kind of electrostatic precipitator (referring to accompanying drawing 3) is arranged, it is by a upright metal cylinder, the bottom of cylindrical shell is that an integrant with it side has air inlet pipe, there is the funneling flue-dust retainer of ash releasing tube and support the lower end, the top of cylindrical shell is that integrant with it upper end has escape pipe, the casing that lower port communicates with cylindrical shell, the hanging beam of cabinets cavity top, be suspended on insulator on the hanging beam by hook, be in upper end in the cylindrical shell vertically downward and be connected corona wire on the insulator, hole by the casing side is installed in the insulator that has through hole on the casing, pass high-voltage conducting wires and high voltage source (figure part omitted) that the insulator through hole is connected with corona wire, the earth connection that connects the formation electric power loop on the funneling flue-dust retainer constitutes.The electrostatic precipitator of this structure is used more general, the normally operation under normal temperature, normal wet more stable working condition of processed dusty gas, and dust removing effects is also fine.When the temperature of the dusty gas that enters deduster, humidity, its dust removing effects significantly descended when dust concentration changed, especially its humidity also increases thereupon during variations in temperature, because the insulator every high-voltage power supply that is connected with corona wire is in the upper box body inner chamber, the easiest puncture on insulator, creepage, short circuit, cause decompression, and dedusting was lost efficacy.

The purpose of this utility model is to disclose a kind of processed dusty gas to people, is not subjected to the influence of temperature, humidity and the dust content of dusty gas, does not puncture creepage short circuit, guarantees a kind of electrostatic precipitator of dust removing effects

The utility model is realized by following structure.

It comprises upright metal cylinder electrostatic precipitator, and metal cylinder is the cylinder of φ 700mm, high 8m, and communicate also integrant lower end has ash releasing tube, a side that the infundibulate flue-dust retainer of dusty gas air inlet pipe is arranged with the lower port of metal cylinder.Be welded on the flue-dust retainer support that has sole on the funnel.Be lifted in the metal cylinder on the axial location perpendicular to the corona wire in the metal cylinder, provide the power cathode of the high-voltage power-supply unit of high voltage electric field to connect by insulator, lead and corona wire, the positive pole of high voltage source is connected by the earth connection on earth connection and the infundibulate flue-dust retainer, constitutes the loop of high voltage electric field.Vibrator is installed on the outer wall of metal cylinder.Be characterized in: the top of upright metal cylinder has to hide in the metal cylinder rainhat rainhat suitable for reading the coil holder that becomes integrally-built connection corona wire with it, the bar on the insulator top on the termination section of coil holder and the cross-arm is connected, be welded with the hole of the cross-arm of installation insulator on the metal cylinder outer wall on the lower side suitable for reading by cross-arm upper end section, by nut insulator is fixed on the cross-arm, be installed in insulator on the cross-arm except having insulating effect, also play the effect of supporting rainhat simultaneously, its bearing height is that coil holder to metal cylinder distance suitable for reading is equal to or greater than 0.3 meter, insulator to the distance between the metal cylinder that is vertically mounted on the cross-arm is equal to or greater than 0.3 meter, and the upper end of corona wire is fixed on the centre of coil holder.

A kind of electrostatic precipitator described in the utility model, because insulator and high pressure inlet wire are in the atmosphere of electric field outside, processed dusty gas is after the discharge suitable for reading of metal cylinder, even if mix processed dusty gas temperature height, high humidity rapidly with atmosphere, mix the back temperature reduces rapidly with atmosphere, humidity also reduces rapidly, be not subjected to the influence of temperature, humidity and the dust stratification of processed dusty gas, can not puncture, the phenomenon of creepage, short circuit, through test, water-sprinkling on the rainhat does not puncture, creepage, short circuit phenomenon yet.In dust removal process, can keep stable highfield all the time, the dust removing effects of stability and high efficiency.After tested, the dust content in row's effect gas drops to 100mg/m ³Below, reached the high standard discharging.It is applicable to the processing of all dust-laden exhaust gas, is particularly useful for having certain temperature, humidity, high dust concentration, and the processing of the gas under the working condition that changes.
