Background
With the increasing deterioration of the environment, especially the problem of air pollution is more and more concerned by people, especially the air pollution condition in China is particularly prominent, the haze environmental protection problem is serious, and the pollutants enter the bodies of people and can cause very adverse effects on the health of people. Therefore, people have become more concerned about the problem of purifying air, and various air purifiers have come to work. The air purifier is a product capable of adsorbing, decomposing or converting various air pollutants and effectively improving the air cleanliness, and along with the improvement of the life quality of people, more and more families start to use the air purifier, particularly in decorated rooms, offices with more people, air-conditioned rooms and the like. Then, in the prior art, only the central air conditioner with the fresh air filtering system can achieve the purification effect, but the disadvantage is that the energy consumption is too high, and for this reason, a heat (cold) recovery device needs to be additionally arranged in the system, and related regulations are issued by the country to require that the heat recovery device must be adopted in some buildings, such as the public building energy saving design standard (GB 50189-. Because many air conditioning system designs in operation now do not consider outdoor so abominable haze pollution when designing, regard outdoor air as clean during the design, heat transfer system does not have air purification system mostly, and the fan system does not also consider purifying unit's windage. Along with the aggravation of haze pollution, an air purification system has to be installed behind a heat exchange system, so that the resistance and the energy consumption of the system are increased on one hand, and on the other hand, in actual construction, the air purification is often abandoned due to the fact that a purification unit is not installed or the power of a fan is insufficient. Even if the air purifier is installed reluctantly regardless of construction possibility, the purification effect, the heat exchange effect, the energy consumption and the noise are great questions, the air purifier used in the family at present adopts a dry type multilayer filtration and adsorption method, the air purifier only filters and separates particulate pollutants in the air when in work, harmful gases in the air such as nitric oxide, oxysulfide, organic gas pollutants and the like are not decomposed and degraded, the pollution source is not fundamentally solved, and in addition, dust accumulated on a filter screen can become a multiplication body of bacteria to form secondary pollution. And current filter screen generally all can not wash, can only change, will make air purifier's use like this have the potential safety hazard.

Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in detail so as not to obscure the embodiments of the invention.
In the following description, detailed components are set forth in order to provide a thorough understanding of embodiments of the present invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.
Referring first to fig. 1, the present invention discloses an air freshener for treating haze, which is used for treating pollutants in indoor air. Specifically, an air freshener for treating haze includes: a treatment device 20, an electric field treatment apparatus 10 and a contaminant collection box 30.
The treatment device 20 is mounted at the air inlet, as shown in fig. 2, and may consist of a filter plate 22, such as an angle iron, and an adsorbent material. In the illustrated embodiment, the adsorbent material is an activated carbon molecular sieve 21 disposed within a filter sheet 22. The filter plates 22 of the treatment apparatus 20 may be provided in a plurality, with a plurality of filter plates 22 being removably attached to one another to facilitate removal of a single filter plate 22 for cleaning or replacement during subsequent use. That is, the processing apparatus 20 may include a plurality of separation and absorption modules each including a filter sheet and an adsorbent disposed in the filter sheet, and adjacent two separation and absorption modules may be detachably connected to each other.
Alternatively, the treatment equipment may be of modular design, with 2 x 2 rotary air intakes of 580mm for one treatment equipment. The periphery of the treatment equipment is made into a filter plate 22 by using angle steel, and the activated carbon molecular sieve 21 is fixed in the filter plate 22 and correspondingly arranged according to the distribution condition of the rotary air inlet machine, so that the wind resistance is reduced. Optionally, the treatment device may be disposed at an angle of 50-80 degrees with respect to the air inlet to increase the contact area and reduce the system resistance, and further optionally, the treatment device 20 may be disposed at an angle of 80 degrees with respect to the air inlet, that is, the activated carbon molecular sieve 21 and the filter plate 22 of the treatment device are disposed at an angle of 80 degrees with respect to the pollutant plane.
The adsorption substance is a determining factor for whether the haze dust can be purified. An appropriate type of activated carbon molecular sieve 21 should be selected, with the main reference specification parameters being: material, porosity, specific surface area and pressure drop. In addition, the activated carbon molecular sieve 21 should adopt a modular design, so as to facilitate cleaning and replacement in the subsequent use process.
As shown in fig. 1, the electric field treatment device 10 includes: the high-voltage electric field 11 is provided with positive and negative electrode plates in the high-voltage electric field 11. The high-voltage discharge electrode 14 is connected to the high-voltage electric field 11 via an insulated wire. In addition, a heating device is provided for ionizing and decomposing the polluted gas in the high-voltage electric field 11 and discharging and cracking the contact gas passing through the high-voltage discharge electrode 14 before the treatment device 20 filters and adsorbs the polluted substances, particularly, the polluted substances adsorbed on the activated carbon molecular sieve 21 by the discharging and cracking.
The pollutants in the electric field are heated by the heating device, and are uniformly and electrically cracked on the surface of the adsorbed substance through the high-voltage discharge electrode 14 to form pollution-free atoms or ions. The discharge cracking system 10 can be controlled by a control system, such as controlling the pressure, the amount of discharge cracking, and the frequency of discharge cracking of the discharge cracking system 10. If the discharge cracking amount is small, pollution-free atoms or ions cannot be formed on the surface of the adsorbed substance, and the purifying and filtering effects cannot be achieved; if the discharge cracking amount is too much, an ash-forming pollution layer is formed to block the air flow from passing through, so that the resistance of the air freshener for processing the haze is increased.
Optionally, the contaminant collecting box 30 includes: a particle contamination room 31, a contaminated gas dust room 32 and an aspirator 34. The particle contamination room 31 is used for receiving the contaminants filtered, adsorbed, separated or electrolyzed by the processing equipment 20. The polluted gas dust room 32 is communicated with the upper part of the particle pollution room 31; the lighter pollutants such as dust and gas in the particle-polluted room can be brought into the polluted gas-dust room 32 and collected under the power of the rotary air inlet machine, and the air suction machine 34 conveys the pollutants (the lighter pollutants such as nitrogen oxides, sulfur oxides, organic gas pollutants and the like which are not completely electrolyzed) in the polluted gas-dust room 32 to the high-voltage electric field 11 for electrolytic treatment again. Of course, the contaminant collecting box 30 may also recover the filtered contaminants by filtering, etc., instead of the single electrolysis.
In the illustrated embodiment, the particulate contamination room 31 and the contaminated gas and dust room 32 are located below the processing apparatus 20, and the particulate contamination room 31 is used for catching, accumulating, and electrolytically filtering the discharge cracked contaminants falling from the upper surface of the processing apparatus 20, and accumulating and collectively processing the particulate dust slurry. Then, the light gas ash type pollutants which are not completely electrolyzed on the upper layer of the particle pollution room 31 enter the pollution gas dust room 32, when the gas dust reaches a certain height, the pollution gas sensor is triggered, the air aspirator is started, and the light gas ash type pollutants which are not completely electrolyzed on the upper layer of the pollution gas dust room 32 are pumped into the high-voltage electric field 11 to be treated into polluted ions and atomic type substances again.
Thereby, the pollutants in the air are filtered and adsorbed to the surface by the treatment device 20, and the dust particles covering the surface of the treatment device 20 enter the particle pollution room 31. Regularly wash the filler again regularly, clear up out the inside residual dust granule, can guarantee the filtering quality of filler.
The treating apparatus 20 is disposed at the air inlet to purify the haze particles at the air inlet, and the gas-dust pollutants on the discharge cracking treating apparatus 20 improve the effect of the decomposition treatment, and the pollutants leaked by the discharge cracking can be re-absorbed in the pollutant collecting tank 30 to be electrolyzed in the electric field and recycled, thereby improving the efficiency.
Referring to fig. 1, to achieve a better decomposition process, the processing equipment 20 may be disposed at an angle to the intake vent, such as between 50 degrees and 80 degrees, and further optionally, at 80 degrees. Like this, the treatment facility can purify the haze granule in the air intake better.
Alternatively, a pollution gas sensor may be arranged in the pollution gas-dust chamber 32, and when the level of the pollutants in the pollution gas-dust chamber 32 reaches the position of the pollution gas sensor, the pneumatic aspirator 34 sends the aspirator 34 in the pollution gas-dust chamber 32 to the high voltage electric field 11. In this way, the opening of the aspirator 34 can be controlled. In addition, one skilled in the art will recognize that multiple contaminant gas sensors may be spaced apart in the height direction of the contaminated gas-dust compartment 32 to precisely control the start and stop of the aspirator 34.
The analysis shows that the beneficial effects of the invention are as follows: the invention adopts the high-voltage electric field and the electrodes to carry out electrical degradation treatment on gas and dust substances in haze into pollution-free ion atom substances, fundamentally eliminates pollution sources, particularly can fundamentally decompose and treat gas pollution ineffective in filtering and adsorbing treatment, and eliminate pollution from sources, in addition, the treatment equipment of the invention can well separate, filter, adsorb and intercept the particulate substances in the haze through the integral design, prevent the particulate substances from entering the air breathed by people, and then is combined with the pollutant collecting box to collect and manage the particulate substances in the haze by separating, filtering, adsorbing and intercepting, so as to reduce the treatment and secondary pollution costs, the pollutants collected and managed in the pollutant collecting box are sent to the high-voltage electric field by the air aspirator among the polluted gas and dust rooms to be treated again, thereby further improving the treatment effect and further fundamentally reducing the pollution sources, in addition, the filtering and adsorbing materials in the treatment equipment can be cleaned and replaced regularly, the mode is flexible in design, the filtering and separating effect can be guaranteed for a long time, the equipment cost can be reduced, the treatment equipment comprises the treatment equipment, an electric field treatment device and a pollutant collecting box, the treatment equipment is arranged at an air inlet and forms a whole with the air inlet, the space is saved, the decomposing and treating effect is good, in addition, pollutants for purification are circularly treated, the purification is thorough, and the invention has great significance and wide prospect in the environment that the current environmental protection haze tends to harm human health.
