Abstract

The utility model relates to equipment of a wet electric precipitator for treating dust-containing acid waste gas. The equipment comprises the wet electric precipitator, and is characterized in that a spray device is arranged at the upper part of a duct collection electrode of the wet electric precipitator; the spray device comprises spray pipes, spray nozzles, a support, a circulating pump, a filter, a flow meter and a pressure gauge; the spray nozzle is downward and towards the dust collection electrode; the spray device at the upper part of the dust collection electrode is provided with a plurality of spray pipes, and each spray pipe is connected with a plurality of spray nozzles; the spray nozzles are in flat fan shapes; the spray nozzles are arranged on both sides of the dust collection electrode, and are inclined inwards for 5 degrees; and the spraying pressure of the spray nozzles is between 0.5Pa to 1Pa. The equipment has the advantages that the spraying is continuous, so that no dust is accumulated on the surface of the dust collection electrode, an electric field is stable, the dust collection efficiency is high, and the requirements of the dust collection electrodes of different types of electric precipitators can be met.

Description

A kind of wet electrical dust precipitator that improves the voltage of electric field fluctuation
Technical field
The utility model relates to a kind of equipment of handling the wet electrical dust precipitator of acid dust-laden exhaust gas.
Background technology
Wet electrical dust precipitator is a kind of equipment of handling dust-laden in the gas discharging, containing the sour corrosion pollutant, and it can effectively reduce the discharging of dust granules in the gas, acid contaminant.Be commonly used in industries such as smelting, metallurgy, chemical industry, cement, like the processing of boiler exhaust gas, the processing of industrial furnace tail gas etc.
Wet electrical dust precipitator mainly contains discharge electrode and dust collector pole constitutes, and on discharge electrode and dust collector pole, feeds dc high-voltage, makes two interpolars produce a high-voltage electrostatic field; In the high-voltage electrostatic field; Ionization takes place in air under the effect of high voltage electric field, produced electronics and ion.When the dust-laden particle passed through the high-pressure electrostatic place, electronics and ion can be adsorbed on the grit, make dust particles.Charged grit moves to dust collector pole under the effect of electric field force, and by the dust collector pole adsorbing and trapping.
Dust on the dust collector pole of conventional wet electrical dust precipitator is removed, and is that rinse water is passed through aqueduct and flowed in the overflow launder, flow out (overflow launder is arranged along dust collector pole pipe upper end is outer), flow down from overflow launder again from dust collector pole upper end edge wall, in the process that flows with the dust band under.In using continuously, produced some problems, mainly contained: 1. dust is prone to deposition in overflow launder, takes the space of whole overflow launder, and the function of overflow launder loses.Dust-laden particle in 2 overflow launders can flow into the dust collector pole pipe with current, makes current on the dust collector pole wall, form inhomogeneous water curtain.3. because water curtain inhomogeneous, make not easy-clear of the dust that sticks on the dust collector pole pipe, influenced the normal operation of electric field, can cause the fluctuation of voltage.4. the inhomogeneous of water curtain can influence dedusting, demist efficient.
The utility model content
The purpose of the utility model is to provide a kind of wet electrical dust precipitator that improves the voltage of electric field fluctuation, can keep the unsuitable laying dust of dust collector pole through this method, and the electric field fluctuation is little, improves efficiency of dust collection.
To achieve these goals; A kind of wet electrical dust precipitator that improves the voltage of electric field fluctuation of the utility model design; Comprise wet electrical dust precipitator; It is characterized in that: the dust collector pole top at wet electrical dust precipitator is furnished with spray equipment, and this spray equipment is made up of shower, nozzle, support, circulating pump, filter, flowmeter, Pressure gauge, and nozzle is down facing to dust collector pole.It is characterized in that: several showers of spray equipment of arranging on dust collector pole top, each shower is connected with several nozzles.It is characterized in that: the nozzle type shape is flat fan type.It is characterized in that: nozzle is positioned at the both sides of dust collector pole, is the angle of introversion 5 degree.It is characterized in that: nozzle spray pressure is between the 0.5-1 crust.The advantage of the utility model is continuous spray, makes not laying dust of dust collector pole surface, and electric field is stable, and dust-collecting efficiency is high, can satisfy the requirement of dissimilar electric cleaner dust collector poles.
Description of drawings
Accompanying drawing 1 is the partial structurtes sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Comprise wet electrical dust precipitator among the figure; It is characterized in that: dust collector pole 1 top at wet electrical dust precipitator is furnished with spray equipment; This spray equipment is made up of shower 2, nozzle 3, support (not drawing among the figure), circulating pump (not drawing among the figure), filter (not drawing among the figure), flowmeter (not drawing among the figure), Pressure gauge (not drawing among the figure), and nozzle is down facing to dust collector pole.It is characterized in that: several showers of spray equipment of arranging on dust collector pole top, each shower is connected with several nozzles.It is characterized in that: the nozzle type shape is flat fan type.It is characterized in that: nozzle is positioned at the both sides of dust collector pole, is the angle of introversion 5 degree.It is characterized in that: nozzle spray pressure is between the 0.5-1 crust.
During use, the start cycles pump makes nozzles spray water be flat fan-shaped and sprays on the dust collecting pole plate.Regulate the flow of flowmeter, observe the state of shower water on dust collecting pole plate and the state that splashes of shower water, make be covered with water curtain on the dust collecting pole plate, the least amount of water of splashing.Can realize continuous spray with the utility model, make not laying dust of dust collector pole surface, and electric field is stable, dust-collecting efficiency is high.
