Abstract
A method and an apparatus for treating a low specific resistance substance, the method comprising the steps of: conducting electrons to the low specific resistance substance with a conductive electrode (301) to charge the low specific resistance substance; the charged low specific resistance substance is attracted by an adsorption electrode (302) and moved toward the adsorption electrode (302). The low-specific-resistance substance is charged in an electron conduction mode, so that the problem caused by easy electricity loss after the low-specific-resistance substance is charged is solved, the low-specific-resistance substance can quickly obtain electrons after losing the electrons, the probability of charging the low-specific-resistance substance is increased, and the low-specific-resistance substance is kept in a charged state, so that the adsorption pole (302) can continuously exert attraction on the low-specific-resistance substance to adsorb the low-specific-resistance substance, and the low-specific-resistance substance treatment method has strong collection capacity and high collection efficiency on the low-specific-resistance substance.
Description
The present invention relates to a method and an apparatus for treating a low specific resistance substance, and more particularly to a method and an apparatus for treating a low specific resistance substance with higher efficiency of collecting a low specific resistance substance.
The current environmental protection field goes through links such as dust removal, desulfurization, denitration, defogging, and black cigarette, blue cigarette, yellow cigarette that the chimney discharged do not have, but white cigarette has been increased. Most of the components of the white smoke are water mist, fine particles, ammonium salt, calcium, nitric acid, aerosol and the like are also included in the water mist, and the water mist is a main pollutant which is urgently solved at present. The currently used cyclone dust collectors, bag dust collectors, condensation mist eliminators, wet electric dust collectors, acid mist eliminators and the like are basically ineffective. For example, at the end of ozone denitration and wet flue gas treatment of boilers and sintering machines, the demister is used for removing flue gas with water, and the actual demister cannot achieve the removal effect due to temperature difference and fine mist characteristics. At present, a wet electrostatic dust collector is mainly used as a treatment means, but due to structural and charge principle deviation, water mist cannot be charged and adsorbed, and the efficiency of treating white smoke is extremely low. Thus, a large amount of the above pollutants are discharged to the atmosphere, forming haze and acid rain. The health of local people is seriously influenced due to the entrainment discharge of escaping dust, ammonium salt, desulfurizer, denitrifier, phenol, high-valence heavy metal and the like. Meanwhile, a large amount of industrial water is discharged, which is not beneficial to saving water resources.
The discharged water mist is a low-specific-resistance substance, the existing technology for treating the low-specific-resistance substance has the problem that the low-specific-resistance substance is easy to lose electricity after being charged, the low-specific-resistance substance discharged into the air cannot be removed, and the problems of acid mist purification and collection in industrial tail gas, for example, are still technical problems which need to be solved at present.

In addition, the ratio of the cross-sectional area of the conductive electrode to the cross-sectional area of the flow channel in some embodiments of the invention may be 99-10%, or 90-10%, or 80-20%, or 70-30%, or 60-40%, or 50%.
The form of the low specific resistance substance in the present invention may be one or a combination of a plurality of forms of a liquid state, a mist state, a solid state, or a plasma state. For example, the low specific resistance substance in the present invention may be a conductive liquid, a conductive mist, a conductive particle, a charged liquid, a charged mist, a charged particle, water, an emulsion, an aerosol, liquefied dust, a multi-substance mixed liquid, a multi-state mixed liquid, a multi-substance multi-state mixed liquid, a mist, an emulsion mist, a multi-substance mixed liquid mist, a multi-state mixed liquid mist, a multi-substance multi-state mixed liquid mist, a haze, steam, acid mist, an aqueous tail gas, an aqueous smoke, a gaseous molecular group, an ionic group, plasma, a conductive powder body, a conductive spray, a conductive dust, an ionic group in a liquid, an ionic group in a gas, a compound in a liquid, a compound in a gas, or the like. The low specific resistance substance in the present invention may be a biological substance containing water, an emulsion, a multi-substance mixed solution, a multi-state mixed solution, or a multi-substance multi-state mixed solution. The low specific resistance substance in the present invention may be a conductor or a semiconductor. The present invention can collect the low specific resistance substance on the adsorption electrode by the above treatment method. The treatment device can be used as an electric coagulation demister and can be applied to recovery of ozone denitration tail gas, dehydration of wet desulphurization flue gas, recovery of wet dedusting escape water, an industrial tail gas demister, an emulsion purifier, an oil mist purifier, an electronic cigarette and a nuclear fusion restraint device. For example, when the treatment device is applied to the recovery of the ozone denitration tail gas, the acid mist formed in the ozone denitration tail gas is a low-specific-resistance substance, and the resistance of each cubic centimeter of the tail gas containing the acid mist is 0.1-1000 ohms; at this time, the method for treating a low specific resistance substance specifically comprises the steps of: allowing the ozone denitration tail gas to flow through a conductive electrode, and conducting electrons to acid mist in the ozone denitration tail gas by the conductive electrode to enable the acid mist to be charged; the adsorption electrode applies attraction force to the charged acid mist; the acid mist moves to the adsorption pole and is attached to the adsorption pole, so that the acid mist in the ozone denitration tail gas is recycled, the direct emission of the acid mist in the ozone denitration tail gas to the atmosphere is avoided, and the atmosphere is polluted.

In one embodiment of the present invention, the conductive electrode is electrically connected to one electrode of the power supply; the adsorption electrode is electrically connected with the other electrode of the power supply. In an embodiment of the invention, the conductive electrode body is electrically connected to a negative electrode of the power supply, and the adsorption electrode body is electrically connected to a positive electrode of the power supply.
The electrification mode of the low-specific-resistance substance is to introduce positive electrons or negative electrons into the low-specific-resistance substance by using the conductive electrode, and the electrification mode can quickly obtain the electrons after the low-specific-resistance substance is easy to lose electricity, so that the low-specific-resistance substance is kept in a charged state, and further, the adsorption electrode can continuously attract the low-specific-resistance substance so as to adsorb the low-specific-resistance substance. Meanwhile, the conductive electrode in the present invention may have a positive potential or a negative potential; when the conductive electrode has a positive potential, the adsorption electrode has a negative potential; when the conducting electrode has negative potential, the adsorption electrode has positive potential, the conducting electrode and the adsorption electrode are both electrically connected with an upper power supply, and particularly the conducting electrode and the adsorption electrode can be respectively electrically connected with the positive electrode and the negative electrode of the upper power supply. The voltage of the power-on power supply is called power-on driving voltage, and the magnitude of the power-on driving voltage is selected according to the environment temperature, the medium temperature and the like. For example, the electrification driving voltage range of the electrification power source can be 5-50KV, 10-50KV, 5-10KV, 10-20KV, 20-30KV, 30-40KV or 40-50KV, and the electrification power source can be used for treating haze in space from bioelectricity. The power supply may be a dc power supply or an ac power supply, and the waveform of the electrical driving voltage thereon may be a dc, sine wave, or modulated waveform. The direct current power supply is used as the basic application of adsorption; sine waves are used for movement, for example, an electrifying driving voltage of the sine waves acts between the conductive electrode and the adsorption electrode, and the generated electric field moves charged particles such as fog drops in the driving electric field to the adsorption electrode; the oblique wave is used for pulling, the waveform is modulated according to the pulling force requirement, for example, the pulling force generated to the medium in the asymmetric electric field has obvious directivity at the edges of two ends of the asymmetric electric field, so as to drive the medium in the electric field to move along the direction. When the power supply adopts an alternating current power supply, the frequency conversion pulse range can be 0.1Hz-5GHz, 0.1Hz-1Hz, 0.5Hz-10Hz, 5Hz-100Hz, 50Hz-1KHz, 1KHz-100KHz, 50KHz-1MHz, 1MHz-100MHz, 50MHz-1GHz, 500MHz-2GHz or 1GHz-5GHz, and the device is suitable for adsorbing pollutants from organisms. The conductive electrode of the present invention can be used as a wire for directly introducing positive and negative electrons into a low specific resistance substance when the conductive electrode is in contact with the low specific resistance substance, and the low specific resistance substance itself can be used as an electrode. In the invention, the low-specific-resistance substance repeatedly obtains electrons and loses electrons in the process of moving from the conducting electrode to the adsorption electrode; meanwhile, a large number of electrons are transferred between the plurality of low specific resistance substances located between the conductive electrode and the adsorption electrode, and finally reach the adsorption electrode, thereby forming a current, which is also referred to as an electric drive current. The magnitude of the power-on driving current is related to the ambient temperature, the medium temperature, the electron quantity, the mass of the adsorbate and the escape quantity. For example, as the number of electrons increases, the number of mobile particles, such as droplets, increases, and the current formed by the moving charged particles increases. The more charged substances such as mist droplets are adsorbed per unit time, the larger the current becomes. The escaping droplets are only charged but do not reach the adsorption electrode, i.e. no effective electrical neutralization is formed, so that under the same conditions the more droplets escape, the lower the current. Under the same condition, the higher the ambient temperature is, the faster the speed of the gas particles and the fog drops is, the higher the kinetic energy of the gas particles and the fog drops is, the higher the probability of collision between the gas particles and the conducting electrode and the adsorption electrode is, and the gas particles and the fog drops are not easily adsorbed by the adsorption electrode, so that the gas particles and the fog drops escape. Meanwhile, since the higher the ambient temperature is, the higher the momentum of the gas molecules, droplets, etc., and the less easily the gas molecules, droplets, etc., are adsorbed by the adsorption electrode, even after the adsorption electrode adsorbs, the probability of escaping from the adsorption electrode again, i.e., escaping after neutralization, is also higher, so that the above-mentioned power-on driving voltage needs to be increased under the condition that the distance between the conductive electrode and the adsorption electrode is not changed, and the limit of the power-on driving voltage is to achieve the effect of air breakdown. In addition, the influence of the medium temperature is substantially equivalent to the influence of the ambient temperature. The lower the temperature of the medium is, the less the energy required for exciting the electrification of the medium, such as fog drops, and the smaller the kinetic energy of the medium itself is, the more easily the medium is adsorbed on the adsorption electrode under the same electric field force, so that the formed current is larger. The treatment device has better adsorption effect on cold substances. As the concentration of media, such as droplets, increases, the more likely it is that the charged media will have electron transfer with other media before colliding with the adsorption electrode, and thus the more chance of effective electrical neutralization, and the correspondingly larger current will be generated; the higher the dielectric concentration, the greater the current that is formed. The relationship between the power-on driving voltage and the medium temperature is substantially the same as the relationship between the power-on driving voltage and the ambient temperature.
In one embodiment of the invention, the power-on driving voltage of the power-on power supply can be smaller than the initial corona starting voltage of the corona starting power supply, and under the condition of no corona discharge, the conducting electrode can also charge a low-specific-resistance substance and can conduct electricity without ionization; when the upper driving voltage can be larger than the initial corona onset voltage of the corona onset power supply, the corona discharge and conducting electrode conducts electrons to the low specific resistance substance, so that the low specific resistance substance is charged and exists at the same time. The corona-starting power supply is a power supply which can enable the conducting electrode or the adsorption electrode to generate discharge when the conducting electrode and the adsorption electrode are both electrically connected with the corona-starting power supply, and the conducting electrode or the adsorption electrode ionizes gas when discharging, so that substances such as smoke dust particles in the gas obtain negative charges. The voltage of the corona onset power supply is called the corona onset voltage, and the minimum value of the corona onset voltage is called the initial corona onset voltage; that is, under the condition that the conducting electrode and the absorbing electrode are both electrically connected with the corona start power supply, the minimum voltage value which can enable the conducting electrode or the absorbing electrode to generate discharge and ionize gas is called as initial corona start voltage. The initial corona voltage may not be the same for different gases, different operating environments, etc. However, it is obvious to those skilled in the art that the initial corona onset voltage is determined for a certain gas and working environment. Meanwhile, in some embodiments of the present invention, the power-on driving voltage may be specifically 0.1-2 kv/mm. The electrifying driving voltage of the electrifying power supply is less than the air corona starting voltage. The method for treating a low specific resistance substance according to the present invention can be applied to the treatment of exhaust gas from an engine, and particularly, a low specific resistance substance such as water mist in exhaust gas from an engine can be treated by the apparatus and the method for treating a low specific resistance substance according to the present invention.
In an embodiment of the invention, the conductive electrode and the adsorption electrode both extend along the left-right direction, and the left end of the conductive electrode is located at the left of the left end of the adsorption electrode.
In one embodiment of the present invention, there are two adsorption electrodes, and the conductive electrode is located between the two adsorption electrodes.
The distance between the conductive electrode and the adsorption electrode in the present invention can be set according to the magnitude of the power-on drive voltage therebetween, the flow rate of the low specific resistance substance, the charging capability of the low specific resistance substance, and the like. For example, the spacing between the conducting electrode and the adsorbing electrode may be 5-50mm, 5-10mm, 10-20mm, 20-30mm, 30-40mm, or 40-50 mm. The larger the distance between the conducting electrode and the adsorption electrode is, the higher the required power-on driving voltage is, so as to form a strong enough electric field for driving the charged medium to move towards the adsorption electrode quickly, so as to prevent the medium from escaping. Under the same condition, the larger the distance between the conductive electrode and the adsorption electrode is, the closer the conductive electrode and the adsorption electrode are to the central position along the airflow direction, the faster the material flow speed is; the slower the flow rate of the substance closer to the adsorption pole; and perpendicular to the direction of the air flow, the charged medium particles, such as mist particles, increase in distance between the conductive electrode and the adsorption electrode, and the longer the time for acceleration by the electric field without collision, and therefore the greater the moving speed of the substance in the perpendicular direction before approaching the adsorption electrode. Under the same condition, if the power-on driving voltage is unchanged, the electric field intensity is continuously reduced along with the increase of the distance, and the capacity of the medium in the electric field for charging is weaker.

In some embodiments of the present invention, the low specific resistance substance treatment apparatus further comprises a casing having an inlet and an outlet, and the conductive electrode and the adsorption electrode are both mounted in the casing. In the process of collecting the low specific resistance substance, the low specific resistance substance enters the shell from the inlet and moves towards the outlet; in the process that the low specific resistance substance moves towards the outlet, the low specific resistance substance passes through the conductive electrode and is electrified; the adsorption electrode adsorbs the charged low specific resistance substance to collect the low specific resistance substance on the adsorption electrode. The invention utilizes the shell to guide the low-specific-resistance substance to flow through the conductive plate, so as to utilize the conductive electrode to charge the low-specific-resistance substance, and utilizes the adsorption electrode to collect the low-specific-resistance substance, thereby effectively reducing the amount of the low-specific-resistance substance flowing out of the outlet.

When a low specific resistance substance such as water mist adheres to the adsorption electrode, condensation is formed. In some embodiments of the invention, the adsorption pole can extend in the up-and-down direction, so that when the condensation accumulated on the adsorption pole reaches a certain weight, the condensation flows downwards along the adsorption pole under the action of gravity and finally is collected in a set position or device, thereby realizing the recovery of the low-specific-resistance substances attached to the adsorption pole. The treatment device can be used for refrigerating and demisting. In addition, the substances adhered to the adsorption plate may be collected by applying an electric field. The direction of the collection of the substances on the adsorption plate can be the same as the air flow or different from the air flow. In specific implementation, because the gravity action is fully utilized, water drops or a water layer on the adsorption pole flow into the collecting tank as soon as possible; meanwhile, the speed of the water flow on the adsorption electrode can be accelerated by utilizing the airflow direction and the acting force thereof as much as possible. Therefore, the above objects can be achieved as much as possible according to different installation conditions, convenience, economy, feasibility and the like of insulation, regardless of specific directions.
In some embodiments of the present invention, the processing device may be used independently as an adsorption device for the low specific resistance substance. Meanwhile, in some embodiments of the present invention, the processing device may be used in combination with a refrigeration device, a catalysis device, a corona device, a heating device, a centrifugation device, a screening device, an electromagnetic device, an irradiation device, etc. to achieve condensation, catalysis, corona, heating, centrifugation, screening, etc. In addition, the devices can be combined randomly according to the field requirement.
In addition, the existing electrostatic field charging theory is that corona discharge is utilized to ionize oxygen, a large amount of negative oxygen ions are generated, the negative oxygen ions are contacted with dust, the dust is charged, and the charged dust is adsorbed by heteropoles. However, the conventional electric field adsorption effect is almost absent when the coating film is exposed to low specific resistance substances such as water mist, metal particles, and conductive dust. Because the low-specific-resistance substance is easy to lose electricity after being electrified, when the moving negative oxygen ions charge the low-specific-resistance substance, the low-specific-resistance substance loses electricity quickly, and the negative oxygen ions move only once, so that the low-specific-resistance substance is difficult to be charged again after losing electricity, or the charging mode greatly reduces the probability of charging the low-specific-resistance substance, so that the low-specific-resistance substance is in an uncharged state as a whole, the unlike pole is difficult to continuously exert the adsorption force on the low-specific-resistance substance, and finally the adsorption efficiency of the existing electric field on the low-specific-resistance substance is extremely low. In some embodiments of the invention, the processing apparatus and the processing method do not adopt a charging mode to charge the low specific resistance substances, but directly transfer electrons to the low specific resistance substances to charge the low specific resistance substances, and after a certain low specific resistance substance is charged and loses electricity, new electrons are quickly transferred to the low specific resistance substance losing electricity through the conductive electrode and other low specific resistance substances, so that the low specific resistance substance can be quickly charged after losing electricity, the charging probability of the low specific resistance substance is greatly increased, for example, repeated times, the low specific resistance substance is in an electricity obtaining state as a whole, and the adsorption electrode can continuously exert attraction on the low specific resistance substance until the low specific resistance substance is adsorbed, thereby ensuring that the processing apparatus has higher collection efficiency on the low specific resistance substance. The method for charging the low specific resistance substance adopted by the invention does not need to use corona wires, corona electrodes, corona plates or the like, simplifies the whole structure of the treatment device, and reduces the manufacturing cost of the treatment device.
