Description

One-way plasma electrostatic purification fresh air machine and operation method
Technical Field
The invention relates to the field of air fresh fans, in particular to a one-way fresh air fan with a plasma electrostatic purification function.
Background
Along with the improvement of living standard of people, the housing level is also greatly improved, the housing is generally changed from the past brick and tile houses to the modern housing with reasonable structure and good heat preservation and sealing performance, but the modern housing also brings a series of problems, one of which is the problem of indoor air quality. As the precision of modern houses during construction is greatly improved along with the improvement of house technology, the sealing performance of the houses is also greatly improved, the improvement of house sealing performance brings about improvement of living conditions due to improvement of heat preservation performance, and also brings about a problem of how to ensure the indoor air quality, because people need to continuously consume oxygen and generate carbon dioxide in daily life, namely, the environment of people needs to be continuously supplemented with fresh air, otherwise, if the people are in the sealed environment without fresh air supplement for a long time, the health of people is seriously affected, and therefore, a fresh air system is a very important household device for modern houses.
The fresh air system is generally divided into a one-way fresh air system and a heat exchange fresh air system, and the heat exchange system is used for simultaneously extracting indoor air and exchanging heat with fresh air supplied to the indoor when the fresh air is supplied to the indoor, so that the heat loss when the air conditioner is started on hot days in summer and cold days in winter is avoided, and the purpose of energy conservation is achieved. The heat exchange fresh air system is also a total heat exchange system according to the heat exchange mode, namely, the total heat exchange system is used for exchanging moisture in air besides heat exchange of cold and hot air, so that drying of indoor air under the condition that an air conditioner is started in summer and winter is avoided.
However, no matter what kind of fresh air system, the systems inevitably have a problem: in the long-term operation process, the dust brought in the air can be continuously accumulated in places such as a fresh air machine, a pipeline, an air inlet, an air outlet and the like, and the dust can often breed bacteria after being accumulated for a long time, so that the health of people is unconsciously damaged.
Meanwhile, the air quality problem, particularly the haze problem, has become a social problem in China, and the haze in autumn and winter, particularly the haze in northern areas, has become a memory of the whole people. Therefore, the air purifier becomes an important life electrical appliance of residents in China, particularly urban residents, and some fresh air systems introduce air purification into the fresh air system to purify fresh air so as to improve the air quality of the fresh air. At present, the method of purifying the fresh air mainly by adopting an HEPA filter screen in a fresh air system adopts the principle that the fresh air passes through the HEPA filter screen with huge adsorption area, the micro-dust particles in the fresh air are adsorbed by the huge adsorption area with a zigzag air path in the HEPA filter screen to achieve the purification purpose, and active carbon adsorption and the like can be added to adsorb some peculiar smell air if necessary. These air purification methods have the advantages of simple structure, low equipment manufacturing cost and mature technology, and are widely applied to the field of air purification. However, this air purification method has certain problems. Firstly, the air resistance of the filter screen is large, and the fresh air system is required to have large air pressure to drive air to pass through the HEPA filter screen, so that not only is the energy consumption increased, but also the noise of the fan is increased, and the daily life of a user, such as rest, can be influenced; meanwhile, the air purification in the mode transfers the micro-dust in the air to the filter screen, and the micro-dust is accumulated on the filter screen for a long time and then often causes secondary pollution due to bacteria breeding and the like, but the quality of the indoor air is affected; thirdly, the HEPA filter screen for purifying air by adsorption has a certain limit of adsorption capacity for adsorbing micro-dust, and needs to be replaced when reaching the limit of adsorption capacity, and the HEPA filter screen is expensive at present, so the long-term use cost is high.
Therefore, the HEPA filter screen type air purification is not an optimal method, not only is the cost high after long-term use, but also secondary air pollution is often caused, and the health of people is damaged.
Besides HEPA filter screen method, air purification also has a method, namely plasma electrostatic purification, which utilizes the principle that opposite charges attract each other, utilizes plasma electrostatic field to charge micro-dust in the air, and then carries out air purification in a way of being adsorbed by polar plates with opposite charges, moreover, the purification method purifies and removes the micro-dust in the air and macromolecular organic matters with peculiar smell, and simultaneously, a high-voltage electric field formed by the purification method also has the function of killing bacteria and viruses in the air, thereby having the function of avoiding secondary air pollution caused by bacteria breeding in the accumulated micro-dust. At present, the air purification mode is not a mainstream product, but has a certain sterilization and disinfection effect due to low long-term use cost, and has wider market potential compared with a HEPA filter screen type air purifier. The invention transplants the air purification technology into a fresh air system, and purifies the air of the fresh air on the basis of solving a series of problems in the practical application of the technology, thereby forming a healthy product after air purification.
Meanwhile, although the heat exchange type fresh air fan used at present has an energy-saving function, on one hand, the energy recovery is limited (actually less than 50%), and on the other hand, many problems still exist.
Firstly, because indoor air is required to be sucked back and exchanged with fresh air, even if the fresh air pipeline is subjected to air purification, the sucked air cannot be purified particularly from a suck-back port, tiny dust can be continuously accumulated on parts of a pipeline, an air port and the like through which the sucked air flow passes, harmful toxic substances such as bacteria and the like are bred, the harmful toxic substances can bring the bacteria into the fresh air after being exchanged with the fresh air to cause secondary pollution of the fresh air, particularly, the harmful substances such as bacteria bred by the tiny dust accumulated on the surface of the total heat exchange membrane can directly enter the fresh air, and the harm is larger.
Secondly, the heat exchange new fan can cause the unbalance of air inlet and outlet volume after long-term use, because in order to guarantee the quality of air inlet, usually can install fly net or coarse strainer at the air inlet, after long time these fly net or coarse strainer are blocked up, the intake will reduce, when the intake is less than the back suction air volume, will form the negative pressure in the room, outdoor air that does not purify will enter into the room through door crack, window seam etc. the quality of new trend will be reduced greatly, has lost the meaning that the new trend purifies even, the efficiency of heat recovery simultaneously also can reduce.
If the fresh air of the one-way fresh air machine is purified, the dust accumulation problem of the airflow pipeline is solved because the dust in the purified fresh air is basically removed, and the quality of the fresh air is effectively guaranteed even in the long-term use process.
Therefore, for the household user, although the purification type one-way fresh air is higher than the heat exchange fresh air fan in energy consumption, the air quality of the fresh air can be ensured, especially, the purification type one-way fresh air fan is purified because the entering fresh air, the dust accumulation phenomenon at the wind flow passing part of a pipeline and the like is greatly improved, and especially, the quality of the fresh air can be effectively ensured without a heat exchange membrane which is most easy to cause dust accumulation and cross air pollution. Meanwhile, the plasma air purification function has the function of sterilizing the air high-voltage electric field actually while purifying the air, so that the quality of the air is further guaranteed, and therefore, the one-way fresh air machine using the plasma purification is an ideal healthy fresh air solution.
However, the practical application of the plasma electrostatic purification method to the unidirectional fresh air machine also needs to solve a series of problems. Firstly, the problem of the purification rate of plasma electrostatic purification is solved because if the efficiency of plasma electrostatic purification is not high, the purified air has certain tiny dust, and the tiny methods can cause secondary pollution to fresh air after years of accumulation, while the tiny dust purification rate of plasma electrostatic air purification using the conventional technology in the current market can only reach the purification rateSuch purification efficiency still can not guarantee to deposit the dirt in the long-term air current pipeline of using for many years. Meanwhile, the conventional plasma air purification device does not solve the problem of secondary air pollution caused by the escape of volatile gas on the surface of a dust collecting electrode after dust deposition in the using process and the problem of ozone generation caused by polarity reversal of a plasma generating electrode caused by the dust deposition on the surface of the dust collecting electrode at present, the conventional plasma air purification product is formed by integrating a plasma generating assembly and the dust collecting electrode, the integrated device is compact and complex, and is not beneficial to daily maintenance of ordinary users without special use, operation knowledge and skills, the application of a plasma electrostatic purification technology in daily life is seriously influenced due to the problems, and the plasma electrostatic purification has no outstanding advantages compared with HEPA filter screen purification due to higher production cost.

Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1-2, the unidirectional plasma electrostatic purification fresh air machine fixedly installed indoors can be installed indoors or outdoors, and includes a main machine 1 for introducing fresh air from outdoors and a bypass air pipe 3 for introducing the bypass air machine 2 from the main machine 1 to outdoors, the main machine 1 includes a housing 4, an air inlet 5 communicated with outdoors, an air outlet 6, a main air machine 7 and a plasma electrostatic purification assembly 8, the plasma electrostatic purification assembly 8 divides an inner cavity of the housing 4 into an air inlet cavity 9 communicated with the air inlet 5 and an air outlet cavity 10 communicated with the air outlet 6, the main air machine 7 is installed at the air outlet 6, the bypass air pipe 3 is installed at the air inlet cavity 9 as shown in fig. 2, or the bypass air pipe 3 is installed at the air outlet cavity 10 as shown in fig. 1. The bypass air pipes can be arranged at the back of the air inlet cavity or the air outlet cavity close to the wall, and can also be arranged at the two sides of the air inlet cavity or the air outlet cavity and then connected to the outside of the wall. When the bypass air pipe is arranged in the air outlet cavity, the air outlet 6 and the bypass air pipe 3 are respectively provided with the check valve 61 and the check valve 31, and when the bypass air pipe 3 is arranged in the air inlet cavity, the air outlet 6 and the bypass air pipe 3 are not provided with the check valves.
The main fan adopts a hyperstatic one-way fan and is divided into more than three wind speeds; PM2.5 detection is carried out before and after the air inlet, and cleaning time from hole plate cleaning, electrode plate cleaning to coarse filter screen cleaning is prompted according to the PM2.5 value difference and fresh air flow accumulated data before and after the air inlet.
In terms of control, a purge redundancy approach may be employed: for example, the time required for normal use is 12 hours, the use effect can be increased by controlling the reserved time to be about 14 hours, namely, the air conditioner is started one hour before use, and is started one hour after the use is not required to further update the air in the room, wherein the starting one hour before use not only can enhance the use feeling, but also can have time for removing the peculiar smell air.
The bypass air pipe 3 is connected to the outside of the wall of a building, the host machine 1 is placed indoors or outdoors and fixedly installed, and before the fresh air fan normally operates to purify air, volatile gas in the shell 4 of the fresh air fan is firstly discharged, and the specific method comprises the following steps: before the main fan 7 is started, the bypass fan 2 of the bypass air pipe 3 is started, under the condition that the bypass air pipe is arranged in the air outlet cavity, the check valve 61 and the check valve 31 are arranged on the air outlet and the bypass air pipe, the check valve 61 of the air outlet is closed by air negative pressure formed by the work of the bypass fan 2 to prevent the air outside the air outlet from flowing back into the machine shell, meanwhile, the check valve 31 in the bypass air pipe 3 is opened by air pressure to form air flow discharged outside the machine shell through the bypass air pipe 3 in the machine shell, the negative pressure in the machine shell caused by the bypass fan 2 sucks air from the air inlet 5, the air flow formed by the air passes through the plasma static electricity generation assembly 81 and the separated type section porous dust collection plate 82, and volatile gas generated on the surface of the air flow is taken away and discharged outside the machine shell through the bypass air pipe 3. Before the purification function of the purifier is formally started, pollutants such as volatile gas which is not restrained by an electric field in the prior art are discharged to the outside by the method, so that the secondary pollution of fresh air introduced into the room is avoided. Under the condition that the bypass air pipe is arranged in the air inlet cavity, negative pressure formed in the shell when the bypass fan 2 works sucks air from the air inlet and the air outlet respectively, airflow is collected into the bypass air pipe and then is discharged out of the room, and therefore volatile gas possibly existing on the surface of the plasma electrostatic purification assembly in the shell and other parts is discharged. For the mode of bypass tuber pipe installation in the air outlet cavity, the efficiency of the mode of bypass tuber pipe installation in the air inlet cavity when discharge volatile gas is less relatively, and the power that bypass fan needs is bigger, needs longer exhaust time simultaneously, but this kind of mode can discharge the volatile gas that the inside position of casing exists more thoroughly.
For the mode that the bypass air pipe is arranged in the air outlet cavity, the check valve of the air outlet can be omitted, but the situation and the mode that the bypass air pipe is arranged in the air inlet cavity have a common problem: when the air is exhausted, the indoor air is sucked back through the air outlet and then exhausted through the bypass air pipe, and micro dust can be accumulated in the air pipe after long-term use, so that secondary pollution of the air is caused. Therefore, the bypass air pipe is arranged in the outlet cavity, and the check valve is arranged at the air outlet, which is a relatively more ideal scheme.
The equipment adopts an indoor fixed mounting mode firstly, a fresh air fan is fixedly mounted on a wall, holes are drilled on the wall, an air inlet 5 and a bypass air pipe 3 are led out of the wall, and a fan cover with a built-in insect-proof net is arranged at the pipe orifice of the air inlet 5 and the bypass air pipe 3 led out of the wall to prevent mosquitoes and large-particle airborne dust from being sucked;
the bypass fan 2 and the bypass air pipe 3 have two installation methods: the air inlet cavity 9 is arranged, namely is arranged in front of a corona generating electrode 811, and check valves are not required to be arranged at an air outlet and a bypass air pipe when the air inlet cavity is started to remove peculiar smell in a machine; the other type is arranged behind an air outlet cavity, namely a separating section porous dust collecting plate 82, and the air outlet 6 needs to be closed by a check valve when the machine is started to remove the peculiar smell air in the machine.
As shown in fig. 3, the plasma electrostatic purification assembly 8 includes a plasma electrostatic generation assembly 81 and a separation type section porous dust collecting plate 82, and the separation type section porous dust collecting plate 82 is located at the rear side of the plasma electrostatic generation assembly 81.
The plasma static electricity generating assembly 81 comprises a plurality of pairs of electrode pairs consisting of corona generating electrodes 811 and counter electrode plates (rods) 812 which are alternately distributed in parallel, wherein the corona generating electrodes 811 are positioned between the two counter electrode plates (rods) 812, an air inlet passage 83 is arranged between the two counter electrode plates (rods) 812, and the air inlet passage 83 is perpendicular to the separating type section porous dust collecting plate 82. The counter electrode plate (rod) 812 is grounded in common with the divided section porous dust collecting plate to improve the safety of the use of the apparatus.
The corona generating electrode 811 is placed behind a counter electrode plate (rod) 812. The separating section porous dust collecting plate 82 is a porous plate structure, and includes a porous conductive plate material such as a foamed metal plate and other foamed conductive materials, a metal or other conductive material screen, and the like, such as a foamed nickel plate, a stainless steel mesh, and the like.
The separating section porous dust collecting plate 82 is located on the section of the air flow in the machine body, can be arranged in the direction perpendicular to the air flow, and can also form a certain angle with the air flow so as to increase the contact area with the air flow and further improve the purification efficiency.
The separating section porous dust collecting plate 82 (porous structure) solves the problem of purification efficiency, solves the problem of ozone generation caused by reversed corona pair formed after the accumulation of the micro-dust on the surface of the dust collecting plate after a period of use, and greatly simplifies the cleaning of a dust collecting pole;
the bypass fan structure solves the problem of secondary pollution of volatile gas.
The separating section porous dust collecting plate 82, especially the foam metal plate material (foam nickel plate, foam copper) with zigzag small holes and the aperture less than 1 mm is used as the section porous dust collecting pole, which greatly improves the purifying efficiency.
The material of the separating section porous dust collecting plate 82 is a foamed metal plate or a metal mesh.
The separating section porous dust collecting plate 82 is composed of one or more layers of foamed metal plates or metal nets, which may be combined together or installed in tandem in front and back independently. The separated section porous dust collecting plate 82 with more than one layer is generally divided into a front stainless steel net and a rear foamed nickel plate, the front stainless steel net is used for adsorbing pollutants, the rear foamed nickel plate is used for cleaning the stainless steel net, and a small amount of residual unadsorbed dust is adsorbed by the foamed nickel plate with a much better adsorption effect, so that the excellent purification effect can be achieved, and the cleaning time interval for cleaning the relatively complex foamed nickel plate is prolonged.
The postposition of corona generating electrode 811 greatly reduces the dust speed of the surface area of the counter electrode plate 812, greatly prolongs the cleaning and maintenance time interval of the corona generating electrode assembly, and reduces the ozone generation: the problem of dust accumulation on the surface of the counter electrode plate 812 is solved by arranging corona wires at the rear side of the counter electrode plate and arranging a corona generating electrode 811 at the rear part.
In a normal electrostatic generating electrode layout, the corona generating electrode 811 is located in the middle of the front and rear edges of the counter electrode plate 812, so that after air enters an electrostatic field and micro dust is charged, the micro dust moves to the counter electrode plate 812 under the action of the electrostatic electrode, and part of the micro dust is accumulated on the surface of the counter electrode plate 812, especially the rear part of the counter electrode plate 812, thereby causing dust accumulation on the counter electrode plate 812. The dust accumulated on the surface of the counter electrode plate 812 causes frequent cleaning of the counter electrode plate 812, and the cleaning process is easy to damage the electrode due to deformation and displacement of the electrode with strict spacing requirements, and meanwhile, the counter electrode plate 812 after dust accumulation is easy to greatly increase the generation amount of ozone.
The corona generating electrode 811 (corona wire) is arranged at the rear part of the counter electrode plate 812, the plasma electrostatic field is mainly distributed at the rear part of the counter electrode plate 812, and the possibility that charged micro-dust is adsorbed on the counter electrode plate 812 when the charged micro-dust moves forward under the driving of the airflow is greatly reduced, so that the problem of dust accumulation on the counter electrode plate 812 is solved, and the cleaning time interval is greatly prolonged.
In order to solve the problem of the influence of the trailing edge of the counter electrode plate 812 on the plasma electrostatic field after the corona generating electrode 811 is placed, the counter electrode plate 812 may be a conductive metal strip or a conductive metal tube (e.g., a diameter) with a certain diameterStainless steel or aluminum alloy strip or tube) mounted in the parallel slots in the rear side of the electrically conductive metal strip or tubeAnd (3) removing the solvent. Fig. 3 and 4 are schematic views of the corona generating electrode and the counter electrode plate 812 or the counter electrode bar. The counter electrode can be plate-shaped, round rod-shaped or round tube-shaped, and the diameter of the round rod-shaped or round tube-shaped counter electrode is larger than that of the corona generating electrode.
As shown in figure 1, the operation method of the indoor unidirectional plasma electrostatic purification fresh air machine is characterized by comprising the following specific steps of 1) opening a bypass fan 2 on a bypass air pipe 3 of an air outlet cavity under the closing state of a main fan 7 positioned at the air outlet, opening a check valve 31 in the bypass air pipe, enabling the bypass fan 2 to form outdoor air flow in the bypass air pipe, forming negative pressure between an air outlet cavity 10 and an inner inlet cavity 9, closing a check valve 61 arranged at the air outlet 6 by the negative pressure of the air outlet cavity 10 to prevent the air flow from flowing back from the air outlet 6, sucking air from an air inlet 5 by the negative pressure of the air inlet cavity 9, and taking volatile gas on the surface of the air out of the air inlet through the surface of a plasma electrostatic purification component and discharging the air out of the room through the bypass air pipe 3; 2) the bypass fan 2 is started for a plurality of times; 3) the bypass fan 2 is closed, the main fan 7 is opened, the check valve 61 of the air outlet 6 is opened by positive pressure formed by the main fan, meanwhile, the check valve 31 in the bypass air pipe 3 is closed by negative pressure formed in the casing, fresh air flow which enters air from the air inlet, is purified by the plasma electrostatic purification assembly and then is sent out from the air outlet is formed, and the fresh air fan enters a normal fresh air working state;
