Description

Technical Field

The present invention relates to a low specific resistance substance treatment method and treatment device, in particular to a low specific resistance substance treatment method and treatment device with higher efficiency for collecting low specific resistance substances.

Background Art

At present, in the field of environmental protection, after dedusting, desulfurization, denitration, demisting, and the like, black smoke, blue smoke and yellow smoke discharged by a chimney do not exist, but white smoke appears. Most of the components of the white smoke are water mist, and fine particles, ammonium salt, calcium, nitric acid, aerosol, and the like are also contained which are the main pollutants to be solved urgently at present. The currently used cyclone dust collector, bag dust collector, condensation demister, wet electric precipitator, acid mist demister, and the like are substantially ineffective. For example, at the end of ozone denitration and wet flue gas treatment of boilers and sintering machines, a demister is used to remove the water carried by the flue gas. However, the actual demister cannot achieve the removal effect at all due to temperature difference and fine mist characteristics. At present, the wet electrostatic precipitator is mainly used as a treatment means. But due to the deviation of the structure and the charging principle, the water mist cannot be charged and adsorbed such that the efficiency for treating the white smoke is extremely low. In this way, a large number of the above-mentioned pollutants is discharged into the atmosphere to form haze and acid rain. Escape dust, ammonium salt, desulfurizer, denitration agent, phenol, high-valence heavy metal, and other entrainment dischargings seriously affect the health of local people. At the same time, a large amount of industrial water is discharged, which is not conducive to saving water resources.
The discharged water mist is a low specific resistance substance, and the existing technology for treating the low specific resistance substance has the problem caused by the low specific resistance substance easily losing power after being charged such that the low specific resistance substance discharged into the air can not be removed. For example, the problem of acid mist purification and collection in industrial tail gas is still a current technical problem to be solved urgently.

In one embodiment of the present invention, the conductive electrode is located in the flow channel. The cross-sectional area of the conductive electrode in the present invention is the sum of the areas of the conductive electrode along the solid portion of the cross-section. 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 present 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 of the present invention may be one or a combination of more than one of a liquid state, a mist state, a solid state, or a plasma state. For example, the low specific resistance substance of the present invention may be conductive liquid, conductive mist, conductive particle, charged liquid, charged mist, charged particle, water, an emulsion, an aerosol, liquefied dust, multi-substance mixed liquid, multi-state mixed liquid, multi-substance multi-state mixed liquid, water mist, emulsion mist, multi-substance mixed liquid mist, multi-state mixed liquid mist, multi-substance multi-state mixed liquid mist, a haze, steam, acid mist, water-containing tail gas, water-containing flue gas, gaseous state molecular group, ionic group, plasma, conductive powder, conductive spray, conductive dust, ionic group in liquid, ionic group in gas, compounds in liquid, compounds in gas, and the like. The low specific resistance substance of the present invention can also be an organism containing water, an emulsion, multi-substance mixed liquid, multi-state mixed liquid, or multi-substance multi-state mixed liquid. The low specific resistance substance of the present invention may be a conductor or a semiconductor. The low specific resistance substance can be collected to the adsorption electrode via the above-mentioned treatment method of the present invention. According to the present invention, the treatment device can be used as an electrocoagulation demister and can be applied to ozone denitration tail gas recovery, wet desulphurization flue gas dehydration, wet dedusting escape water recovery, industrial tail gas demister, emulsion purifier, oil mist purifier, electronic cigarette, and nuclear fusion restraint device. For example, when the treatment device is applied to ozone denitration tail gas recovery, the acid mist formed in the ozone denitration tail gas is a low specific resistance substance, and the resistance of the tail gas containing the acid mist per cubic centimeter is 0.1 to 1000 ohms; at the time, the low specific resistance substance treatment method specifically includes steps as follows: the ozone denitration tail gas flows through the conductive electrode, and the conductive electrode conducts electrons to the acid mist in the ozone denitration tail gas and electrifies the acid mist; the adsorption electrode exerts attractive force to the charged acid mist; the acid mist moves to the adsorption electrode and is attached to the adsorption electrode such that the acid mist in the ozone denitration tail gas is recovered, and the acid mist in the ozone denitration tail gas is prevented from being directly discharged to the atmosphere and polluting the atmosphere. At the time, the above-mentioned treatment method is also referred to as an acid mist static electricity recovery method. The treatment device and treatment method of the present invention can be used for whitening treatment of escape mist, aerosol, and the like discharged by chimneys of power plants, glass plants, steel plants, and chemical plants. The present invention solves the problem that the traditional wet electric precipitator cannot remove low specific resistance substances contained in the discharged gas, including water mist, acid mist, aerosol, emulsion, liquefied dust, and the like, and directly utilizes an electric field to adsorb and recover the low specific resistance substances contained in the tail gas by adopting a space power-on mode. In addition, the treatment method and device of the present invention can also be used for separating or enriching a target substance, i.e., low specific resistance substance, from the gaseous phase, a liquid phase, or a sol body. According to 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 to the other electrode of the power supply. According to one embodiment of the present invention, the conductive electrode is specifically electrically connected to the negative electrode of the power supply, and the adsorption electrode is specifically electrically connected to the positive electrode of the power supply.
According to the power-on mode of the low specific resistance substance of the present invention, positive electrons or negative electrons are conducted into the low specific resistance substance through the conductive electrode such that through the power-on mode, the low specific resistance substance can quickly obtain electrons after easily losing power, the low specific resistance substance is enabled to remain charged, and the adsorption electrode can continuously attract the low specific resistance substance to adsorb the low specific resistance substance. Meanwhile, the conductive electrode of the present invention can 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 conductive electrode has a negative potential, the adsorption electrode has a positive potential, the conductive electrode and the adsorption electrode of the present invention are both electrically connected to a power-on power supply, and specifically, the conductive electrode and the adsorption electrode can be respectively electrically connected to the positive electrode and the negative electrode of the power-on power supply. The voltage of the power-on power supply is called a power-on driving voltage, and the size of the power-on driving voltage is selected in relation to the ambient temperature, the medium temperature, and the like. For example, the range of the power-on driving voltage of the power-on power supply may be 5-50KV, 10-50KV, 5-10KV, 10-20KV, 20-30KV, 30-40KV, or 40-50KV, from bioelectricity to spatial haze treatment electricity consumption. The power-on power supply may be a direct current power supply or an alternating current power supply, and the waveform of the power-on driving voltage may be a direct current, a sine wave, or a modulation waveform. The direct current power supply serves as the basic application of adsorption; the sine wave is used as the movement, for example, the power-on driving voltage of the sine wave acts between the conductive electrode and the adsorption electrode, and the generated electric field moves charged particles in the driving electric field, such as fogdrops and the like, to the adsorption electrode; the oblique wave is used as pulling, and the waveform needs to be modulated according to the pulling force, and as at the edges of the two ends of the asymmetric electric field, the pulling force generated by the medium therein has significant directionality to drive the medium in the electric field to move in that direction. When the alternating current power supply is used in the power-on power supply, the range of the frequency conversion pulses 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, suitable for the adsorption of organisms to contaminant particles. The conductive electrode of the present invention can be used as a conductive wire such that positive electrons and negative electrons are directly conducted into a low specific resistance substance when the conductive electrode is in contact with the low specific resistance substance, and at the time the low specific resistance substance itself can serve as an electrode. In the procedure that the low specific resistance substance moves from the conductive electrode to the adsorption electrode according to the present invention, electrons are repeatedly obtained and lost; at the same time, a large number of electrons are transferred between a 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 a power-on driving current. The magnitude of the power-on driving current is related to the ambient temperature, the medium temperature, the electron quantity, the adsorbed substance quantity, and the escaping quantity. For example, as the electron quantity increases, the number of movable particles, such as fogdrops, increases, and the current formed by the movable charged particles increases accordingly. The more charged substances, such as fogdrops, adsorbed per unit time, the larger the current. The escaped fogdrops are only charged, but do not reach the adsorption electrode. That is, no effective charge neutrality is formed, so that under the same conditions, the more escaped fogdrops are, the smaller the current is. Under the same conditions, the higher the ambient temperature is, the faster the velocity of the gas particles and fogdrops is, the higher the kinetic energy of the gas particles and fogdrops is, the higher the collision probability of the gas particles and fogdrops with the conductive electrode and the adsorption electrode is, and the less easily they are adsorbed by the adsorption electrode, thereby generating escape. But because the escape occurs after the charge neutrality and possibly after repeated charge neutralities, the electron conducting velocity is accordingly increased, and the current is accordingly increased. Meanwhile, the higher the ambient temperature is, the higher the momentum of gas molecules, fogdrops, and the like is, and the less easily they are absorbed by the adsorption electrode, even after the adsorption electrode adsorbs, the higher the probability of escaping from the adsorption electrode again, i.e. escaping after charge neutrality, is. Therefore, under the condition that the distance between the conductive electrode and the adsorption electrode is unchanged, the power-on driving voltage needs to be increased, and the limit of the power-on driving voltage is to achieve the effect of air breakdown. In addition, the effect of the medium temperature is substantially comparable to that of the ambient temperature. The lower the medium temperature is, the smaller the energy required to excite the medium, such as fogdrops to charge is, the smaller the kinetic energy that the medium has is, the more easily the medium is adsorbed to the adsorption electrode under the same electric field force, and the larger the formed current is. The treatment device in the present invention has a better adsorption effect on cold substances. With the increasing concentration of the medium, such as fogdrops, the probability that the charged medium has generated electron transfer with other mediums before colliding with the adsorption electrode is larger such that the chance of forming effective charge neutrality is larger, and the formed current is correspondingly larger; therefore, the higher the concentration of the medium is, the larger the formed current is. The relationship between the power-on driving voltage and the medium temperature is substantially the same as that between the power-on driving voltage and the ambient temperature.
According to one embodiment of the present invention, the power-on driving voltage of a power-on power supply can be smaller than the onset corona inception voltage of the discharge inception power supply. Under the condition that corona discharge does not exist, the conductive electrode of the present invention can also charge the low specific resistance substance so that the electricity can be conducted without ionization; when the power-on driving voltage can be larger than the onset corona inception voltage of the discharge inception power supply, the corona discharge and the conductive electrode conduct electrons to the low specific resistance substance such that the low specific resistance substance is charged and simultaneously exists. The discharge inception power supply is a power supply that enables the conductive electrode or the adsorption electrode to generate discharge if both the conductive electrode and the adsorption electrode are electrically connected to the discharge inception power supply, and ionizes gas when the conductive electrode or the adsorption electrode generates discharge such that substances such as smoke dust particles in the gas obtain negative charge. The voltage of the discharge inception power supply is called discharge inception voltage, and the minimum value of the discharge inception voltage is called onset corona inception voltage; that is, under the condition that both the conductive electrode and the adsorption electrode are electrically connected to the discharge inception power supply, the minimum voltage value at which the conductive electrode or the adsorption electrode can generate discharge and ionize the gas is called the onset corona inception voltage. The magnitudes of the onset corona inception voltages may be different for different gases, different working environments, etc. However, for a person skilled in the art, with regard to determined gas and working environment, the corresponding onset corona inception voltage is determined. Meanwhile, in some embodiments of the present invention, the power-on driving voltage may specifically be 0.1-2kv/mm. The power-on driving voltage of the power-on power supply is smaller than the discharge inception voltage of air corona. In addition, the low specific resistance substance treatment method of the present invention can be applied to the treatment of tail gas of an engine, and particularly the low specific resistance substance treatment device and treatment method of the present invention can be used for treating low specific resistance substances such as water mist and the like in the tail gas of the engine.
In one embodiment of the present invention, both the conductive electrode and the adsorption electrode extend in the left-right direction, and the left end of the conductive electrode is located to 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 two adsorption electrodes.
According to the present invention, the distance between the conductive electrode and the adsorption electrode can be set according to the power-on driving voltage magnitude between the conductive electrode and the adsorption electrode, the flow rate of the low specific resistance substance, the charging capacity of the low specific resistance substance, and the like. For example, the distance between the conductive electrode and the adsorption electrode may be 5-50mm, 5-10mm, 10-20mm, 20-30mm, 30-40mm, or 40-50mm. The larger the distance between the conductive electrode and the adsorption electrode is, the higher the required power-on driving voltage is, to form a strong enough electric field for driving the charged medium to quickly move to the adsorption electrode 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 to the central position, the faster the substance flow rate is along the gas flow direction; the closer the substance is to the adsorption electrode, the slower the flow rate of the substance is; in the direction perpendicular to the gas flow direction, the longer the time the charged medium particles, such as mist particles are accelerated by the electric field as the distance between the conductive electrode and the adsorption electrode increases under the condition of no collisions, and therefore, the larger the moving velocity of the substance in the perpendicular direction is before the substance is near the adsorption electrode. Under the same conditions, if the power-on driving voltage is not changed, the strength of the electric field decreases gradually with the increase of the distance, and the weaker the charging capacity of the medium in the electric field is.
In some embodiments of the present invention, the conductive electrode may be one or a combination of more than one of a solid, a liquid, a gas molecular group, or plasma. When the conductive electrode is solid, the conductive electrode can be made of solid metal, such as 304 steel, or other solid conductors, such as graphite, and the like; when the conductive electrode is a liquid, the conductive electrode may be an ion-containing conductive liquid. In addition, in some embodiments of the present invention, the conductive electrode can also be a conductive mixed state substance, an organism naturally mixed conductive substance, and an object artificially machined to form a conductive substance. In the present invention, the adsorption electrode is made of a conductive substance, or the surface of the adsorption electrode has a conductive substance.
In some embodiments of the present invention, the conductive electrode may have a shape of a facet, mesh, perforated plate, plate, spherical cage, box, or tube. The mesh in the present invention is in a shape that includes any porose structure. When the conductive electrode is in the form of a plate, a spherical cage, a box or a tube, the conductive electrode may be of a non-porose structure or a porose structure. When the conductive electrode is of a porose structure, one or more through-holes can be formed in the conductive electrode, and the through-holes in the conductive electrode can have a polygonal, circular, oval, square, rectangular, trapezoidal, diamond shape, and the like. The through-hole on the conductive electrode may have a profile size of 0.1-3mm, 0.1-0.3mm, 0.3-0.5mm, 0.5-0.8mm, 0.8-1.0mm, 1.0-1.2mm, 1.2-1.0mm, 1.0-1.5mm, 1.5-1.8mm, 1.8-2.0mm, 2.0-2.3mm, 2.3-2.5mm, 2.5-2.8mm, or 2.8-3.0mm. In addition, in some embodiments of the present invention, the conductive electrode may have a shape of other natural states of the substance, or machined states of the substance. In the present invention, when the low specific resistance substance passes through the through-hole on the conductive electrode, the low specific resistance substance passes through the conductive electrode, the contact area of the low specific resistance substance and the conductive electrode is improved, and the charging efficiency is increased. In the present invention, the through-hole in the conductive electrode is any hole that allows a substance to flow through the conductive electrode.
Meanwhile, in some embodiments of the present invention, the adsorption electrode may have a shape of a multilayer mesh, mesh, perforated plate, tube, barrel, spherical cage, box, plate, particle stacked stratiform shape, bent plate, or panel. When the adsorption electrode is in the form of a plate, spherical cage, box, or tube, the adsorption electrode may also be a non-porose structure, or a porose structure. When the adsorption electrode is of a porose structure, one or more through-holes can be formed in the adsorption electrode, and the through-hole of the adsorption electrode can have a polygonal, circular, oval, square, rectangular, trapezoidal, rhombic shape, or the like. The through-hole in the adsorption electrode may have a profile size of 0.1-3mm, 0.1-0.3mm, 0.3-0.5mm, 0.5-0.8mm, 0.8-1.0mm, 1.0-1.2mm, 1.2-1.0mm, 1.0-1.5mm, 1.5-1.8mm, 1.8-2.0mm, 2.0-2.3mm, 2.3-2.5mm, 2.5-2.8mm, or 2.8-3.0mm. In the present invention, the through-hole in the adsorption electrode is any hole that allows a substance to flow through the adsorption electrode.
In some embodiments of the present invention, an electric field is formed between the conductive electrode and the adsorption electrode, and the electric field can be various electric fields such as a mesh surface electric field or a mesh barrel electric field. For example: the conductive electrode is in a mesh shape, the adsorption electrode is faced, and the conductive electrode is parallel to the adsorption electrode to form a mesh surface electric field; or the conductive electrode is in a mesh shape and fixed through a metal wire or a metal needle, the adsorption electrode is in a barrel shape, and the conductive electrode is located at the geometric symcenter of the adsorption electrode such that a mesh barrel electric field is formed. When the adsorption electrode is faced, it may specifically be a plane, curved face, or spherical face.

In one embodiment of the present invention, the insulating member is made of insulating mica. In one embodiment of the present invention, the insulating member is columnar or tower-shaped. In one embodiment of the present invention, the conductive electrode is provided with a cylindrical front connecting portion, and the front connecting portion is fixedly connected to the insulating member. In one embodiment of the present invention, a cylindrical rear connecting portion is provided on the inner wall of the adsorption electrode or the shell, and the rear connecting portion is fixedly connected to the insulating member.
In some embodiments of the present invention, the low specific resistance substance treatment device further includes a shell having an inlet and an outlet, both the conductive electrode and the adsorption electrode being mounted in the shell. In the procedure of collecting low specific resistance substances, the low specific resistance substance enters the shell from the inlet and moves to the outlet; in the procedure of the low specific resistance substance moving to the outlet, the low specific resistance substance passes through the conductive electrode and is charged; the adsorption electrode adsorbs the charged low specific resistance substance to collect the low specific resistance substance to the adsorption electrode. According to the present invention, the shell is used for guiding the low specific resistance substance to flow through the conductive plate such that the low specific resistance substance is charged by using the conductive electrode, and the adsorption electrode is used for collecting the low specific resistance substances, thereby effectively reducing the quantity of the low specific resistance substance flowing out from the outlet. In some embodiments of the present invention, the shell may be made of metal, non-metal, conductor, non-conductor, water, various conductive liquids, various porous materials, or various foam materials, and the like. When the shell is made of metal, the material can specifically be stainless steel or aluminum alloy, and the like. When the shell is made of non-metal, the material can specifically be cloth, or sponge, and the like. When the shell is made of a conductor, the material can specifically be iron alloy and the like. When the shell is made of a non-conductor, a water layer is formed on the surface of the shell to form an electrode, such as a sand layer after water absorption. When the shell is made of water and various conductive liquids, the shell is static or flowing. When the shell is made of various porous materials, the shell can be specifically made of molecular sieve or activated carbon. When the shell is made of various foam materials, the shell can be specifically made of foamed iron, foamed silicon carbide, and the like. In an embodiment of the present invention, the conductive electrode is fixedly connected to the shell through the insulating member, and the insulating member can be made of insulating mica. Meanwhile, in an embodiment of the present invention, the adsorption electrode is directly electrically connected to the shell in such a way that the shell can have the same potential as that of the adsorption electrode such that the shell can adsorb charged low specific resistance substance, and the shell also constitutes an adsorption electrode. The shell is provided therein with the flow channel, and the conductive electrode is mounted in the flow channel.
When a low specific resistance substance such as water mist is attached to the adsorption electrode, condensation is formed. According to some embodiments of the present invention, the adsorption electrode can extend in the up-down direction such that when the condensation stacked on the adsorption electrode reaches a certain weight, the condensations will flow downwards along the adsorption electrode under the action of gravity and finally aggregate in a set position or device, thereby realizing the recovery of low specific resistance substances attached to the adsorption electrode. The treatment device can be used for refrigerating and demisting. In addition, substances attached to the adsorption plate can also be collected by the manner of an extra electric field. The direction of collecting the substances on the adsorption plate can be the same as or different from that of the airflow. During the specific implementation, the action of gravity is to be fully utilized such that water drops or water layers on the adsorption electrode can flow into a collecting tank as soon as possible; meanwhile, the airflow direction and acting force thereof will be utilized as much as possible to accelerate the velocity of the water flow on the adsorption electrode. Therefore, according to different mounting conditions, and the convenience, economical efficiency, feasibility, and the like of the insulation, the object can be achieved as far as possible without restricting the present invention to a specific direction.
In some embodiments of the present invention, the above-mentioned treatment device may be used independently as an adsorption device for low specific resistance substance. Meanwhile, in some embodiments of the present invention, the treatment device can be combined with a refrigerating device, a catalyzing device, a corona device, a heating device, a centrifugal device, a screening device, an electromagnetic device, an irradiation device, and the like for the use to realize the functions of condensation, catalysis, corona, heating, centrifugation, screening, and the like. In addition, any combination of the above devices may be used as desired in the field.
In addition, the currently existing electrostatic field charging theory utilizes corona discharge to ionize oxygen to generate a large number of negative oxygen ions. The negative oxygen ions are in contact with the dust, the dust is charged, and the charged dust is adsorbed by a heteropole. However, when encountering water mist, metal particles, conductor dust, and other low specific resistance substances, the existing electric field adsorption effect hardly exists. Because the low specific resistance substance easily loses power after being electrified, when the moving negative oxygen ions charge the low specific resistance substance, the low specific resistance substance will lose power quickly. The negative oxygen ions move only once such that the low specific resistance is difficult to recharge after losing power, or the charging mode greatly reduces the probability that the low specific resistance substance is charged. So the low specific resistance substance is in an uncharged state as a whole. In this way, it is difficult for the heteropole to continuously exert adsorption force to the low specific resistance substance, finally causing the adsorption efficiency of the existing electric field to the low specific resistance substance to be extremely low. According to the treatment device and the treatment method in some embodiments of the present invention, instead of charging the low specific resistance substances via electrical charge, electrons are directly transferred to the low specific resistance substances to charge the low specific resistance substances. After a certain low specific resistance substance is charged and loses power, new electrons are quickly transferred to the power lost low specific resistance substances through other low specific resistance substances from the conductive electrode. So the low specific resistance substance can be quickly electrified after losing power, and the charging probability of the low specific resistance substance is greatly increased. This being repeated, the low specific resistance substance is in an electrified state as a whole, and the adsorption electrode can continuously exert attractive force to the low specific resistance substance until the low specific resistance substance is adsorbed such that the high collection efficiency of the treatment device on the low specific resistance substance is ensured. According to the method for charging the low specific resistance substance adopted by the present invention, corona wires, corona electrodes, corona plates, and the like are not needed such that the whole structure of the treatment device is simplified, and the manufacturing cost of the treatment device is reduced. Meanwhile, by adopting the power-on mode, according to the present invention, a large number of electrons on the conductive electrode are transferred to the adsorption electrode through the low specific resistance substance, and an electric current is formed. The larger the concentration of the low specific resistance substance flowing through the treatment device is, the more easily electrons on the conductive electrode are transferred to the adsorption electrode through the low specific resistance substance, and more electrons are transferred between the low specific resistance substances such that the current formed between the conductive electrode and the adsorption electrode is larger, the charging probability of the low specific resistance substance is higher, and the collection efficiency of the treatment device on the low specific resistance substance is higher. The treatment method in the present invention can be used as a novel method for chimney whitening and demisting. The treatment device in the present invention can be additionally provided on a wet electric dust collector.
