Abstract
The invention relates to a device used for fluid purification and gas-liquid separation. The device is a comprehensive device integrating mist removal and dust removal, and is a technical device special for a certain clearance. The device is excellent in performance, can prevent discharge of micrometer aerosol flue dust particles, smaller than PM2.5 particles, and is suitable for acid preparation from fuel coal and smelting fuel gas, tail gas processing of titanium dioxide calcination, and gas-liquid separation and efficient recycling of acid mist in industries such as sulfuric acid of chemical plants. The device also can be used as an electric deduster for clearing dust in flue gas, and is an electric-arc-type demister that enables a discharge concentration to be reduced to 1 mg/N*m<3>.
Description
Technical field
The present invention and one are used for purifying fluid and gas-liquid separation equipment, can be used for fire coal, metallurgical off-gas acid-making, titanium dioxide calcining the industry such as vent gas treatment, all kinds of sulphuric acid in chemical plant acid mist carry out gas-liquid separation, high efficiente callback, it is alternatively arranged as electric cleaner to use, can be used for removing the dust in flue gas, concentration of emission all can be made to drop to the arc type demister of below 1mg/Nm.
Background technology
Known: at present, old-fashioned electrostatic precipitator operation principle: by electrostatic control means and high direct voltage generating means, alternating current is become unidirectional current and delivers in demister, powerful electric field is formed between corona wire (negative electrode) and acid mist trapping pole plate (anode), air molecule is made to be ionized, moment produces substantial amounts of electronics and positive and negative ion, these electronics and ion make directed movement under the effect of electric field force, constitutes the medium of trapping acid mist.Making acid mist microgranule charged, these charged acid mist particles, under the effect of electric field force, make directed movement simultaneously, arrive on the positive plate of trapping acid mist.Afterwards, charged particle discharges electronics on pole plate, and then acid mist is collected, and flows in the storage acid tank of deacidification day with fog under gravity, has thus reached to purify the purpose of acid mist.But due to existing corona wire (negative electrode), to discharge electron number limited, and nano level acid mist droplet surface area is little, wall effect causes the electron number of nano level acid mist droplets to increase, due to nano level acid mist droplets electronics very little, its Coulomb attraction being had is the least, so trapping can not be attracted by positive plate, it the most all can be wrapped up in association by air-flow and emit.In decades, although relevant expert attempts, try hard to improve in various manners charge capacity, but because there is charged wall effect, so, electrostatic precipitator performance does not improves always.The existence of this technical problem, cause the most various electric cleaner dust-collecting efficiency the lowest, at one's wit's end to below PM2.5 micron order aerosol smokeshade, it is discharged into air to suffer always, therefore, if solving below PM2.5 micron order the most nano level acid mist liquid droplet capture problem, certain meaning is said, the most just avoids occurring haze to produce from source.
Summary of the invention
For the deficiency overcoming existing electric cleaner, electrostatic precipitator technology to exist, for making the acid mist of fire coal, metallurgical off-gas acid-making, the titanium dioxide calcining industry such as vent gas treatment, all kinds of sulphuric acid in chemical plant can obtain thorough gas-liquid separation, reclaimed efficiently.It is an object of the invention to provide the arc type of a kind of ultrapurification except mist cleaner unit and manufacture method thereof.
The present invention solves technical problem and be employed technical scheme comprise that.
AC high voltage is applied on the electric plug discharge electrode in neoteric a kind of Novel spark discharger, it is allowed to produce spark arc, again direct current negative pole high-tension electricity is applied in spark arc, the high temperature of spark arc, the meeting a large amount of negatron of heat emission, a large amount of negatrons can form powerful electron wind, not only make nano level acid mist drop negative ion, and, under electron wind wraps up in association, the charged nano level acid mist drop of negative ionization can quickly move merit and fly to the positive plate of positively charged, nano level acid mist drop can be on positive plate plate, it is adsorbed being condensed into sour water, sour water can take advantage of a situation after gradually increasing and under, in inflow collection box.
Arc type demister provides the benefit that.
1. arc type demister, is that collection is except mist, dust removal integrated comprehensive device, it is possible to be specifically designed to the technique device of a certain special cleaning.Its function admirable, can stop the discharge of below PM2.5 micron order aerosol smokeshade, the concentration of emission after the dedusting of industrial smoke can be made to drop to below 1mg/Nm.
2. arc type demister, it removes mist, the field gas velocity of dedusting can improve 3-5m, and according to old-fashioned field gas velocity 0. 8m, several times that equipment volume is little, therefore, compact structure, technique is simple, and cost operating cost is the lowest, and it is the most convenient to install maintenance.
3. arc type demister can be applicable to coal-burning boiler, metallurgical off-gas acid-making, titanium dioxide calcining tail gas except mist dust removal process, the acid mist being suitable for the industries such as chemical plant all kinds of sulphuric acid except mist dust removal process, gas-liquid can be made to be completely separated recovery, thus reduce atmospheric pollution.
