Description
Technical Field
The invention belongs to the technical field of air purifiers, and particularly relates to a technology integrating a wet air dust removing method and a foam air dust removing method.
Due to the universality, the invention can expand multiple purposes, for example, the invention can be used for sterilizing and disinfecting air when large-scale air germs spread, and preventing disease spread. Can also be used for increasing the concentration of negative ions in the air to improve the air quality.
Background
With the development of the age, the progress of science and technology, various pollution and the consequences thereof are becoming obvious, and seriously influence the daily life of people and endanger the health of the masses. Summarizing, the cause of haze formation is largely categorized into two aspects: first, weather causes; second, for human reasons. Haze is essentially a "non-aqueous aerosol" in which the relative humidity is saturated by more than 90% when the "haze" is formed and the relative humidity is less than 80%. The two function together to form haze.
The reasons for artifacts and weather are in particular:
1. the warm moisture flows down, so that surface water vapor cannot rise, and the air humidity increases to form mist.
2. The lower particles of industrial waste gas, automobile exhaust, building dust and the like are mixed into the fog in a large quantity, wherein the proportion is as follows: 15% of soil dust, 18% of fire coal, 25% of industrial pollution, 12% of biomass combustion, 4% of automobile tail gas, and 26% of secondary inorganic aerosol. These substances form haze when mixed with the fog.
3. As the pollutants are increased and the high air temperature of the reverse temperature layer is higher than the low air temperature, horizontal calm wind and vertical reverse temperature are caused, suspended particles are continuously increased, and haze is further aggravated and cannot be diffused.
The above is a factor of the conditions for forming haze, and we will analyze the component layers of the haze constituent substances. Haze is composed of a mixture of haze and mist, wherein constituent components of the haze are substantially water molecules. The haze comprises the following components: carbon dioxide, sulfur dioxide, nitrogen oxides (mainly nitrogen dioxide), suspended particulate matter (including PM 10-2.5).
Through analysis of the substance components and analysis of various causes of haze, if only fire coal is simply reduced, the method of controlling the emissions of production enterprises cannot completely solve the haze problem, and all restriction measures restrict the economic development.
The existing air purification technology is numerous and can be roughly divided into four blocks. The method comprises the following steps: physical purification, electrostatic purification, chemical purification, and other purification methods. A brief overview of each purification process will be provided below.
1. Physical purification method
The purification method is divided into: adsorptive filtration, mechanical filtration. Wherein the adsorptive filter carrier is activated carbon. Most of mechanical filter carriers are HEPA nets, and the working principle of the mechanical filter carriers is that suspended particles in air are adsorbed on the carriers by a physical method, so that the mechanical filter carriers have the defects that no matter what carrier is used, only suspended particles can be adsorbed, and toxic and harmful gases are not absorbed. And has the defects of low adsorption efficiency, easy desorption and the like. The HEPA mesh used in the mechanical adsorption method has the defects of low air flow rate and low purification speed in actual work, and the material used by the carrier has certain radiation to human bodies.
2. Electrostatic purification method
The purifying method is to remove suspended particles in the air by making the particles in the air flowing through the equipment charged and utilizing the principle of suction of positive and negative charges. The purifying method has the defects that only particulate matters with a certain radius size in the air can be adsorbed, and certain requirements are imposed on the humidity of the air to be purified. And the method can not adsorb toxic and harmful gases in the air.
3. Chemical purification method
The method adopts various medicament methods such as a photocatalysis method, a formaldehyde scavenger method and the like, and the methods all utilize chemical substances to react with toxic and harmful gases in the air so as to absorb the toxic and harmful gases or convert the toxic and harmful gases into gases with relatively low toxicity. The method has the defects that the used chemical agent has certain toxic and side effects, the treatment is not good, the secondary pollution is easy to be introduced, the method is mainly useful for toxic and harmful gas substances, and the absorption effect on suspended particles is not ideal.
4. Other purification methods
Other air purifying methods are mainly technological means, and the principle is basically physical purifying methods and chemical purifying methods. Only two approaches involving the present invention will be described and summarized herein as having advantages and disadvantages. Wet dust removal method: the method utilizes the physical principle, utilizes a high-pressure centrifugal fan to press dust-containing gas into a water tank with a certain height, uniformly divides the gas to flow from bottom to top, then utilizes water as a carrier, and utilizes two forms of water bath and spray to act on air together to spray water mist so as to achieve the effect of capturing suspended particles in the air. The method has the defects of high-pressure equipment, high energy consumption and high moisture content of the treated air, and defogging treatment is needed, otherwise, the content of fog in haze is increased. The method can remove suspended particles in the air and can not treat toxic and harmful gases.
Foam dust removal method: according to the method, a physical principle is utilized, dust-containing gas enters a sieve plate hole from the side part of a cylinder body through the action of a large ventilator, and water on the sieve plate is blown up to a foam layer with a certain height due to the action of air flow, so that the contact area of air and liquid is increased, and suspended particles in the air are washed out. The method has the defects that the air bubble holes are easy to be blocked and the air bubble effect is poor along with the more dust matters collected. And only can capture suspended particles in the air, and can not treat toxic and harmful gases.
Besides the method, a water film dedusting method is widely applied, and the working principle of the method is that dust-containing gas is introduced from the lower part of the cylinder body tangentially, rises in a rotating way, dust particles are separated under the action of centrifugal force and thrown to the inner wall of the cylinder body, and the dust particles are adsorbed by a water film layer flowing on the inner wall of the cylinder body, but the method has more requirements on air in operation, for example, the dust content of treated air is not more than 25%, otherwise, the machine body is easy to damage, the machine body cannot be used in a working environment of dew, otherwise, cloth bags in equipment are damaged, and water is easy to be stagnant. The problems of large equipment height, difficult arrangement and the like also exist. And the method can not treat toxic and harmful gases in the air.
Disclosure of Invention
The invention provides a cleaner capable of cleaning haze, which mainly solves the following problems:
1. absorb toxic and harmful gases in haze. By chemical means, toxic and harmful gases are chemically reacted with chemical substances to be absorbed, rather than simply diluted in the atmosphere or simply physically adsorbed.
2. Adsorb suspended particulate matter in haze. And capturing and collecting suspended particulate matters of PM 10-2.5 by a physical method, and purifying the particulate matters in the air.
3. The artificial generation conditions change the weather factor that causes haze formation. The horizontal static wind in a large environment is influenced and changed through a plurality of local breeze, and then the vertical reverse temperature is influenced, so that the meteorological factors forming haze are broken.
The invention aims at improving the innovation based on the principles of wet dust removal and foam dust removal. Meanwhile, the defects of the two methods are overcome, and the purposes of purifying harmful gases in the air and removing suspended particles in the air are achieved.
The invention can work by the design of the box body channel only by using a common fan and normal temperature and normal pressure, does not need a high-pressure environment, and reduces energy consumption. The polluted air is treated in stages, so that the advantages of a wet dust removal method and a foam dust removal method are fully exerted. And each stage of work is closely connected, the independent repeated energy consumption is avoided, uninterrupted air purification can be connected, and the purification efficiency is improved.
The invention has three technical problems to be solved at all: 1 removing particulate matters in the air, 2 removing toxic and harmful gases in the air, and 3 introducing no new secondary pollution (comprising chemical substances and water mist) after the air is purified.

The box-type air purifying device adopts a cuboid box-type structure to form a cuboid air purifying channel, three purifying units are formed in the purifying channel, polluted air continuously passes through each purifying unit in the flowing channel unit and the purifying requirement of each purifying unit is finished, and finally the air is purified. The following are technical scheme brief descriptions of three purification units:
a first purifying unit:
the unit is an air purification first step, polluted air is blown into a box body channel by a common fan, when air flows through the stage, solution sprayed by a rain shower and atomized solution particles sprayed by an atomization spray nozzle act on flowing air together, when the solution contacts with the air, suspended particles in the air are physically collided with liquid particles and atomized liquid particles to be captured (the principle is that the air becomes fresh and clean after raining), and the suspended particles captured in the stage can be captured from larger particles to PM 2.5. And the toxic and harmful gas chemically reacts with the solution and is converted into other chemical substances so as to be absorbed. The used solution is sodium hydroxide solution, and the solution is alkaline solution, so that the solution is easy to chemically react with carbon dioxide, sulfur dioxide and nitrogen oxides in the air to generate corresponding salts, and the generated corresponding salts can be recovered to prepare corresponding chemical preparations, thereby avoiding resource waste and new pollution. The sodium hydroxide solution used in the stage is proportioned according to the use requirement, and is recycled through a circulating filtration system in the stage until the effective components in the solution are used up due to the reaction of absorbing harmful gases, and then the solution is replaced by a new solution.
The chemical reaction equation of the solution absorbing toxic and harmful gases in the stage is as follows:
CO2+2NaOH===Na2CO3+H2O
SO2+2NaOH===Na2SO3+H2O
NO+NO2+2NaOH===2NaNO2+H2O
the air purified by this stage reaches the primary purification requirement, and the toxic and harmful gas and most of air suspended particles are removed, but sodium hydroxide liquid small particles and atomized particles are generated due to the spraying and rain effect, and the air is treated in the next stage.
A second purifying unit:
the main function of this stage is to treat the sodium hydroxide droplets and atomized liquid droplets introduced after the first purification unit.
This stage will use air deflectors and water absorbing screens to fulfill the processing requirements of this stage.
The air guide plate structure is similar to a shutter structure, has a plate surface with a larger cross-sectional area, and enables air with liquid drop water molecules to collide with the guide plate surface while changing the air flow direction, and after the water molecules collide with the guide plate surface, larger liquid drop particles are captured by the plate surface, and smaller atomized particles are partially captured. And a porous water absorbing net is arranged behind the guide plate to collect uncollected atomized liquid drops. The number of the deflector stages, the angular positions of the deflector clamps and the like are determined according to practical conditions, and the purpose of removing atomized liquid drop particles is achieved.
And a third purification stage:
after the first and second stages of purification are completed, the air basically meets the treatment requirement, but the purification stage is specially arranged for achieving better purification effect and not introducing secondary pollution.
The final treatment requirement is achieved by utilizing the principle of a foam dust removal method. Through the advantages of the foam method, the method is used in the final stage of air treatment, so that not only can the residual suspended particulate matters in the air be removed, but also the residual atomized droplet particles in the air can be removed, and the final treatment requirement is met.
The stage is provided with vertical net plates, bubblers are placed in the meshes, foaming liquid flows down from the top ends of the net plates at a constant speed, passes through the plate surface and covers each mesh, when air enters the stage from the second purifying stage, the air must flow through each mesh to enter the stage, and bubbles are continuously formed under the combined action of the foaming liquid and the bubblers in the meshes. The air flowing through the bubble is wrapped in the bubble, and of course, the residual suspended particulate matters and sodium hydroxide atomized droplet particles in the air are wrapped in the bubble, collide with the inner wall of the bubble and are finally captured, and the bubble is broken and captured by bubble liquid. The foaming liquid is alkaline according to the formula proportion, a blocking net is arranged at the tail end of the foaming liquid, bubbles which are not broken in a period of time after being generated are broken under the action of the blocking net, the broken bubbles are accumulated and collected and then are recovered to the liquid state of the foaming liquid, and the foaming liquid is recycled through a circulating filtering device until the effect of bubbles is not ideal, and new liquid is replaced.
The above is a brief description of three purification process stages, although the process flow is described in three stages, and the purification process is performed continuously. After this stage, the air reaches the purification requirement, and besides the three purification stages, various functions can be expanded. For example: when the disease is exploded through the air flow, disinfectant or medicine spray can be added at the air purification end to disinfect and sterilize the air flowing through the channel. The anion generator can also be added to increase the anion content of the air flowing through the air, thereby improving the air quality and the like.
Compared with the prior art, the invention has the beneficial effects that:
the invention has simple structure, low energy consumption and easy installation and operation, and can remove toxic and harmful gases and air suspension particulate matters with different diameters. Meanwhile, the multifunctional air purifier can expand multiple functions and meet multiple air purification requirements. The equipment can be large or small in size, can be used for purifying household air, and can also be used as public purifying facilities in public places. In public clean facilities, local breeze is formed in the continuous air purifying process, and a plurality of local breeze flows change the weather factor of forming haze, namely horizontal calm wind and vertical reverse temperature.
