Description
The invention belongs to the heavy poly-technical field of static.
The heavy poly-technology of high-pressure electrostatic is that most important static one of is used.Electrostatic precipitator is applied to from earlier 1900s all obtain very big development at aspects such as theory research, structural shape and ranges of application since the industry such as generating, metallurgy, cement, papermaking and chemistry.The electrostatic precipitator principle is normally by the metal tube of certain diameter or the parallel steel plate of certain distance is arranged (parallel channels commonly used at present is wide 200～350 millimeters, wide spacing is 400～1000 millimeters), connect the high-voltage DC power supply positive pole, and be ground connection, discharge electrode in metal tube center or parallel steel plate mid-mounting, (answering making alive commonly used is 40～72 kilovolts to connect the high-voltage DC power supply negative pole, wide spacing is 80～200 kilovolts, divide direct current and two kinds of power supplys of pulse), normally 100～400 ℃ of running temperatures, so resistant to elevated temperatures high-tension insulator is all adopted in the negative pole insulation, quartz socket tube etc., working voltage adds to corona discharge, produce " corona effect " on the discharge electrode surface, when the dust air communication is crossed the electric field passage, make powder dust particle by just, the anion direction of motion is driven in discharge electrode and dust collector pole (mainly driving to dust collector pole), and the dry type cottrell just, negative pole sinks poly-dust generally falls dust by rapping; Irrigated precipitator then is to gather dust by moisture film.Many patents were once proposed for the structural shape of cottrell and the range of application of gathering dust abroad.The difference of various electrostatic precipitators is mainly by the different physical property of required capture, the particle characteristics of chemistry are developed, as flyash, metal powder, cement, mist of oil, its character of particulates such as acid mist differs widely, particularly in granularity, viscosity, resistivity, temperature, character such as corrosivity and secondary fly-up has very big-difference, need to adopt the dust collecting pole plate of relative unlike material, discharge plume, exhausted level and shape, also will consider to remove the method that captures thing and satisfy the requirement that captures different particles, supply unit then adopts HVDC output circuit, the high-voltage dc pulse output circuit, also there is the computer control circuit of employing to meet the demands.More than, be the heavy poly-technology of modern static in the characteristics of electricity aspect gathering dust.High voltage electrostatic precipitator is successfully used in a lot of fields, yet up till now, the inventor does not also see the heavy poly-technology recycle-water from water smoke of high-pressure electrostatic, and this high-voltage electrostatic water collector, and industrial water smoke also is in the large tracts of land emptying.Water smoke is meant 5～100 microns the particle globule of being generally of visibility, the emptying temperature is between 0～70 ℃, and industrial electro dust-precipitator design temperature is generally at 100～400 ℃, water anacidity, caustic corrosion, but action of rust is arranged, a series of characteristics such as resistivity is low, therefore must adopt special high voltage electrostatic device to finish and receive the water purpose, high-pressure electrostatic water device is to be different from the heavy poly-device of existing high-pressure electrostatic, because the purpose difference more all has the requirement of many uniquenesses in material use, structural configuration, implementation condition etc.
Purpose of the present invention is the retracting device that proposes with regard to being the water smoke that loses at water for industrial use rich and influential family emptying, to reach a large amount of water for industrial uses that reclaim from water smoke, conserve water resource, reduction industrial cost.
Purpose of the present invention can reach by following measure: high-voltage electrostatic water collector is mainly formed, is made up of several layers of parallel aluminium sheet or conductive plastic plate, anti-flammability selvage guide shape material, corrosion resistant plate (flat board or corrugated plating) positive electrode by positive electrode, negative electrode, high voltage direct current generator, High-Voltage Insulation and structure-steel framing, and support by structure-steel framing, also available stainless steel of structure-steel framing or aluminium are made, the number of plies optionally determines, can reach 1000 layers even more.(conductive plastics is to add wire in the plastic powders that adopts moulding to use, metallic fiber, sheet metal or than the little metal dust or a carbon black of degree of plastic powders evenly mixes and heats and makes).Negative electrode also is made up of several layers of discharge framework that is suspended between positive plate, arrange the stainless steel wire (can be garden line, astroid, jaggies etc.) of uniform density in the framework, also but arranged crosswise is network plane (netting the aluminium net of available common specification), or make opposite planar in the framework with aluminium sheet, the conductive plastic plate of hackle mark, negative pole insulation is adopted to rely on and is installed the high pressure support insulator on the anodal structure-steel framing additional and carry out the method (Fig. 2) that cross-arm hangs, or adopts and rely on the anodal structure-steel framing backguy method (Fig. 3) that insulate to reach the purpose that negative pole hangs.Because operating mode needs, above situation also can adopt general layout methods such as concentric garden, tubular, the square bodily form, its key be still keep both positive and negative polarity be arranged in parallel constant, do not lose really resembling of this device.The positive pole of high voltage direct current generator makes all positive plate positively chargeds by structure-steel framing, and ground connection, presents earth potential; The negative pole of high voltage direct current generator then makes all negative plates electronegative by parallel wire.The positive plate spacing can design in 200～1000 millimeters scopes, answers making alive to select in 40～200 kilovolts, and electric-field intensity is 1～3 kv/cm, and current density is at 100～1000 microamperes/meter
2(relevant with negative pole corona intensity) pole plate free height is at 1000～3000 millimeters, and both positive and negative polarity interval error scope is in 3～10 millimeters.Water smoke is when the electric field passage, and charged water mist particle then flies to gather on positive and negative electrode by the migration velocity of 10～30 cels and flows down, and a part of water mist particle is because polarized in electric field, assembles gravity mutually and forms water droplet on the way greater than lift and fall.
