Description
Technical Field
The invention relates to an air purifier. In particular, the present invention relates to an air purifier designed to purify air of an indoor space of a building, such as a living room, an office, a conference room, and the like.
Background
From CN105605687A, an air purifier is known, which comprises: a housing; an air inlet in the housing, the air inlet being designed to allow air to enter the housing; an exhaust port in the housing, the exhaust port being configured to exhaust air out of the housing; a blower in the housing to generate an airflow from the inlet port to the outlet port; and at least one filter designed to purify the gas flow from the gas inlet to the gas outlet. In addition, the air purifier also has a humidifier, a dehumidifier, a heat exchanger, a control unit, and a sensor unit with a humidity sensor and a temperature sensor. By means of this air purifier, the temperature and humidity can be regulated in such a way that people in the room space feel comfortable. Furthermore, contaminants such as dust, bacteria, toxic gases are also filtered out by means of filters.
However, in addition to humidity and temperature, there is an additional factor that contributes to the comfort of people in the indoor space. When people spend a long time in a closed room, the long time can cause indoor CO2The content is increased by human respiration. CO 22The increase in content is the cause of the beginning of people getting tired and inattentive, which also leads to health problems. In this case, there is a tendency to open the window by artificially creating ventilation. This results in a lower CO2A content of outside air flows in, but this outside air also contains many of the said pollutants. Therefore, CO in the indoor space2The content decreases but, conversely, the content of pollutants in the indoor air increases.
Disclosure of Invention
The invention therefore provides a method suitable for conditioning (in particular reducing) CO in an indoor space2Content of air purifiers.
According to the invention, this problem is solved by means of an air purifier having the features of patent claim 1. Advantageous embodiments and developments of the invention are indicated in the subsequent dependent claims.
In addition to conditioning (especially reducing) CO in the indoor space2In addition to the content, the present invention also advantageously saves energy because the warmth or coolness of the indoor space is not sacrificed when ventilating with the outside air. Allowing outside air to enter indoor space without opening windows to reduce CO in indoor air2And (4) content.
According to the invention, a bioreactor is provided which is arranged on and/or in the housing such that the gas flow flowing through the air purifier passes through it and which contains at least one substance capable of removing CO contained in the gas flow by means of photosynthesis2At least partially converted to O2The life form of (1).
Therefore, the air purifier according to the present invention can adjust CO in indoor air2In an amount such that a person feels comfortable in an indoor space. Furthermore, CO contained in the indoor air2Will not be transmitted toOutdoor air, and therefore, it is not necessary to lay pipelines outdoors. Thus, the CO in the room air is purified by means of the air purifier according to the invention2The filtering out does not require connection to outside air, for example, from an outlet of the indoor space. Thus, a perfect indoor climate is provided for the persons in the indoor space, wherein in particular the O in the indoor space is increased2Content of CO in indoor air is reduced2And (4) content. Thus, no harmful and/or toxic substances are used, nor are such substances produced. In addition, CO2Nor in the storage medium from which it must subsequently be released.
The at least one filter is preferably adapted to filter airborne pollutants from the air flowing through it. Airborne pollutants are generally coarse dust, fine dust, viruses, bacteria, microorganisms, odors, pollen, smog and/or compounds, in particular organic compounds, and Volatile Organic Compounds (VOCs), which may be harmful to human health. The at least one filter may be an electrostatic filter and/or an air scrubber. Preferably, at least one filter is a filter having a solid filter media. For example, the at least one filter is a triple filter combination consisting of a pre-filter and a high performance particulate filter or a HEPA filter or a high performance HEPA filter and an activated carbon filter.
An air inlet port disposed within the housing, an air outlet port disposed within the housing, a blower disposed within the housing, at least one filter, and a bioreactor are arranged such that a flow of air flowing from the air inlet port to the air outlet port passes directly through the at least one filter and the bioreactor. Preferably, the components are arranged such that the gas stream flows first through the at least one filter, then through the bioreactor, and then through the vent. Thus, the bioreactor has an air inlet for receiving a flow of air and an air outlet for exhausting air from the bioreactor. The bioreactor has at least one life form designed to at least partially remove CO contained in the gas stream by means of photosynthesis2Conversion to O2. Therefore, the life form of photosynthesis and coarse dust, fine dust, virus, etc. can be prevented,Bacteria, microorganisms, odors, pollen, fumes and/or organic compounds, and/or may prevent the accumulation of the above-mentioned airborne pollutants to be filtered in the bioreactor, since they have been removed by the at least one filter in the air flowing through the bioreactor.
Photosynthesis can be caused by plants, algae and/or bacteria as a life form designed to at least partially remove CO contained in a gas stream2Conversion to O2. Thus, this is the case of oxygen-containing photosynthesis. In oxygenic photosynthesis, energy-rich organic compounds such as carbohydrates, in particular glucose, are separated from energy-poor inorganic substances such as CO with the aid of one or more light-absorbing pigments such as chlorophyll2And in water to produce O2. Plants and algae require light for photosynthesis. Without light, the process of respiration that damages plants and algae begins.
Thus, the basic idea of a bioreactor is to reduce CO by photosynthesis life form activity2The life forms convert CO by means of photosynthesis2At least partially converted to O2. The bioreactor preferably has a vessel containing water and life forms. If air is now introduced into the container, at least one of the life forms utilizes photosynthesis to bring about CO in the air2Into an energy-rich organic compound, at least one life form of which uses the organic compound for cell growth. Then, air (with reduced CO)2) And then discharged from the bioreactor and thus from the air purifier. The air purifier may have its own light source, although this is not required. Preferably, it has a lighting device, since conditions for permanent photosynthesis can be achieved thereby.
The bioreactor is preferably arranged outside the housing. Which is preferably arranged on the housing in relation to the intended operating position of the air purifier. For example, the housing and bioreactor may be designed such that the bioreactor may be attached to the housing. And thus is easily replaced. If desired, the bioreactor and/or the housing may have one or more fixing elements which may additionally fix the attached bioreactor to the housing. Thus, for example, if the air purifier is knocked over, the bioreactor may be prevented from lifting from and/or separating from the housing.
Preferably, at least one photosynthetic life form is selected to be low in CO2Exhibits stable growth under partial pressure.
In a preferred embodiment, the at least one photosynthetic life form is at least one alga. Algae are plant-like life forms. The term "algae" is understood to be a form of eukaryote living in water and performing photosynthesis. Due to their size, algae can be divided into two groups. The microscopically small species are called microalgae; including in particular single cell forms and small multicellular forms. Microalgae are invisible to the naked eye. In contrast, macroalgae or large algae are multicellular and can be seen with the naked eye. The advantage of using algae compared to plants is that there are no debris such as roots, dead leaves, flowers, etc. and that water consumption is low.
Traditionally, cyanobacteria are referred to as "cyanobacteria". The name "cyanobacteria" is used for all cyanobacteria and also for algae which do not contain phycocyanin as a photosynthetic pigment and do not stain blue-green. Previously, they were considered as algal plants, i.e., algae, and classified as blue algae. However, in contrast to algae, cyanobacteria do not have a true nucleus and are therefore prokaryotes. As prokaryotes, they have no relationship to eukaryotes called "algae", and strictly speaking, they are not algae at all. However, in the context of the present invention, the term "algae" also includes cyanobacteria. Thus, in addition to the eukaryotic forms described above, the term "algae" is to be understood as also including cyanobacteria that live in water and undergo photosynthesis.
The at least one alga is preferably selected from the group consisting of cyanophyceae (cyanobacteria and green algae), chlorophyceae (green algae), silylium (diatoms) and chrysophyceae (chrysophyceae). For example, the at least one algae is selected from the group consisting of isochrysis (trichophyceae, chrysoberiopiloidea), chaetoceros (chaetoceros, diatoms), chlorella (unicellular green algae) and/or arthrospira (spirulina-phycophyta (blue algae)).
More preferably, the at least one photosynthetic life form is at least one microalgae. Preferably, at least one of the algae is a spirulina and/or chlorella. Spirulina belongs to the genus cyanobacterium, which in the sense of the present invention belongs to the blue algae, whereas chlorella is freshwater algae.
Preferably, the at least one photosynthetic life form is contained in the bioreactor as a suspension culture. This means that life forms do not grow on glass or plastic, but are a suspension in a fluid medium. However, each life form need not exist separately; these life forms may also exist as multicellular aggregates. The fluid medium is preferably water.
In a further preferred embodiment, the bioreactor is designed as a plate reactor. Thus, the light in the bioreactor is more evenly distributed. The flat-bed reactor functions according to the principle of an airborne reactor. The reactor has a column of gas bubbles through which the gas bubbles flow. Circulation is achieved by controlled introduction of air within the loop defined by the structure. Thus, each individual life form will reach the reactor surface in a short time and thus benefit from light. The bioreactor is preferably configured such that air is introduced from the bottom and discharged from the top relative to the intended operating position.
The bioreactor is preferably designed as a multi-skin patch provided with at least one membrane module through which the gas stream flows. By means of the membrane module, strong gassing of the life forms inside the bioreactor can be avoided.
In a preferred embodiment, the air purifier further has a lighting unit. This has the advantage that it can also reduce CO in air when placed in a dark room where no light enters2And (4) content. The lighting unit is preferably arranged on and/or in the bioreactor in relation to the intended operating position of the air purifier. The lighting unit is preferably arranged within the bioreactor. Thereby ensuring optimal and direct illumination of the bioreactor. Registered light energy of a lighting unit with CO to be converted2The quantities are directly related in order to achieve optimal operation.
The illumination unit may be coaxially arranged in the bioreactor. In this case, the bioreactor is preferably designed as a tube which is provided at both ends with membrane modules through which the gas stream flows. By means of the membrane module, extensive gassing of life forms in the bioreactor can be avoided.
The lighting unit preferably has a Light Emitting Diode (LED). These are inexpensive. The lighting unit advantageously has one or more LED panels.
In photosynthesis, all visible wavelengths of the electromagnetic spectrum are utilized. However, there are different types of chlorophyll, which are designed to absorb light of a specific wavelength. Thus, the color of the light is a determining factor for the use of energy. In particular, the photosynthetic life forms are designed to absorb red and blue light for photosynthesis. In a preferred embodiment, the lighting unit is designed to emit wavelengths in the red range. The emission wavelength of red light is in the range of 620 to 780 nm.
In another preferred embodiment, the air purifier additionally has a humidifier and/or a humidity sensor. This allows adjusting the parameters of the ambient humidity in the indoor space. This parameter is an important factor for the comfort of a person in an indoor space.
Preferably, the air purifier is further provided with a temperature sensor. This allows the temperature of the indoor space to be regulated by means of the air purifier and/or by means of the heating unit of the building in which the indoor space is located. Temperature is also an important factor for the comfort of a person in an indoor space.
In particular, when the air purifier has a humidifier, a humidity sensor, and a temperature sensor, CO of indoor air may be controlled2Content, temperature and humidity to make the person feel comfortable in the indoor space. All three parameters-temperature, humidity and CO-can then be adjusted2Content, which is essential for the comfort of a person in the indoor space.
Preferably, the air purifier also has a WLAN module. The WLAN module is preferably designed to be connected to a controller and/or regulator unit outside the air purifier, which is designed to control one or more parameters of the air purifier, such as the light entering the bioreactor by means of the lighting unit, the operating power of the blower, the intensity of the airflow through the air purifier, the humidity level to be reached in the indoor space and/or the temperature to be reached in the indoor space. For example, the controller and/or regulator unit may be a component of SmartHome. Alternatively or additionally, the air purifier may also have a control panel and/or one or more adjustment buttons or the like by means of which one or more of the above-mentioned parameters may be adjusted.
In a preferred embodiment, the device has a pump which is designed to supply air from the housing and thus from the interior space to the bioreactor. Preferably, the pump is designed such that it can distribute air bubbles in the bioreactor, thereby optimizing the contact time between the air and the at least one life form. The performance of the pump is preferably adjustable so that it can be adapted to the indoor space and to a given CO2And (4) loading. Preferably, the pump is designed and arranged such that the bioreactor and the biological form and water therein can be circulated. Preferably, the pump is provided within the air cleaner such that air from the blower is supplied to the air cleaner. Preferably, the pump is disposed between the bioreactor and the blower.
Preferably, the device has a compressor designed to compress CO in the gas stream2Concentration, the gas stream is supplied to the life forms in the bioreactor. In this way, performance can be further improved.
In a preferred embodiment, the bioreactor may be attached to a lighting unit. If desired, the user may replace the lighting unit and/or container by removing it from the housing without the user having to contact at least one life form. The risk of contamination during replacement, e.g. by microorganisms, bacteria, viruses, etc., can be avoided. Preferably, the container is inserted as an inert, self-contained system so that the user can replace the entire container without the user having to come into contact with life forms. Thus, the lighting unit and/or the bioreactor are preferably removably connected to, e.g. attached to, the housing. The user can thus replace the bioreactor, for example for recycling.
The air purifier is preferably designed to be free standing. The housing is preferably designed to be free standing on a surface such as a table top or the like.
The air purifier may be used as an air purifier in an indoor space, such as a living room, an office, a conference room, a classroom, etc., in which one or more persons may live. It is also conceivable that the air purifier operates in a central heating system, a ventilation system, an air conditioning system or an air handling system of a building in which one or more persons do not live directly.
