Description

Technical Field

[0001] The present invention relates to the technical field of air purification and storage, and in particular to a system and method for forest air treatment and storage of oxygen and phytoncide gas. Background Art

[0002] With the rapid development of modern urbanization, urban air quality has become a focus of public attention. Air pollution in cities mainly comes from industrial emissions, traffic exhaust, construction dust and other factors, which lead to a decrease in oxygen content in the air and an increase in harmful substances, posing a serious threat to human health. Therefore, it is particularly important to find and develop clean and healthy air resources.

[0003] As the "green treasure house" on earth, forests have rich oxygen content in the air and are rich in phytoncide gases that are beneficial to the human body. Phytoncide is a volatile organic compound released by plants, which has multiple biological activities such as antibacterial, anti-inflammatory, and anti-allergic, and has a significant promoting effect on human health. However, due to the limited forest resources and geographical restrictions, people cannot enjoy the benefits of forest air anytime and anywhere.

[0004] In order to introduce oxygen and phytoncide from forest air into cities and provide people with healthy and natural air resources, scholars and research institutions at home and abroad have conducted a lot of research and exploration.

[0005] At present, there are some technologies that can realize the collection and purification of forest air, but most of them have problems such as large design scale and high energy consumption. The invention patent with application number CN201711081982.1 uses a vacuum pump 7 to evacuate the system pipeline and the air inlet buffer tank 2, the compressor 3, the condenser 4, the first gas tank 5, and the second gas tank 6 to a vacuum state, and discharges the extracted gas into the outside air. At the same time, the cooling device is started to reduce the temperature of the system pipeline, equipment, the first gas tank 5, and the second gas tank 6 to the required temperature, and the branches and leaves residue after collecting phytoncide are used as fuel. The combustion process is recovered through heat, and the smoke purification device generates high-temperature steam that enters the bottom of the pot and evaporates upward, and the effective phytoncide in the plant is taken out with the steam, and then collected and stored. However, the overall design has many devices and large energy consumption. At the same time, the collection of phytoncide gas is achieved by collecting plant branches and leaves for vacuum absorption. The treatment method of plant branches and leaves is destructive and not conducive to sustainable operation.

[0006] Therefore, in view of the above problems, the present invention proposes a system and method for forest air treatment and storage of oxygen and phytoncide gases. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technologies and provide a system and method for forest air treatment and storage of oxygen and phytoncide gas.

[0008] In order to solve the above technical problems, the technical solution provided by the present invention is a system for forest air treatment and storage of oxygen and phytoncide gas, the system comprising:

[0009] a) Air collection device for collecting fresh air from the forest environment;

[0010] b) an air filter, connected to the air collection device, for removing dust and particulate impurities in the collected air;

[0011] c) an air compressor connected to the air filter and used to pressurize the filtered air;

[0012] d) a polymer sieve filter, connected to the air compressor, using a polymer sieve material with selective permeability, capable of efficiently separating nitrogen from the air while retaining oxygen and phytoncide gas;

[0013] e) a micro-pressure storage tank connected to the polymer sieve filter, used to temporarily store the separated oxygen and phytoncide gas and maintain a certain pressure;

[0014] f) a gas compressor connected to the micro-pressure storage tank for further pressurizing the stored gas;

[0015] g) a high-pressure gas storage cylinder, connected to the gas compressor, for storing pressurized oxygen and phytoncide gas at high pressure, wherein the internal gas pressure is 12-15 MPa;

[0016] The components of the system are connected in sequence to form a complete system for collecting, purifying, separating and pressurizing forest air for storage.

[0017] Furthermore, the air compressor and the gas pressurizer both adopt an oil-free design to avoid oil pollution of the treated gas.

[0018] Furthermore, the high-pressure gas storage cylinder also includes a pressure monitoring and safety release device for real-time monitoring of the pressure inside the cylinder and automatically releasing the pressure when overpressure occurs, thereby ensuring safe operation of the system.

[0019] Furthermore, the polymer sieve filter is provided with an exhaust pipe for discharging the separated nitrogen.

[0020] A second object of the present invention is to provide a method for treating and storing oxygen and phytoncide gas in forest air by the above-mentioned system, comprising the following steps:

[0022] b) Remove dust and particulate matter from the air through air filters;

[0023] c) Use an air compressor to pressurize the filtered air and control the pressure at 0.3-0.42Mpa;

[0027] g) Store the pressurized gas in a high-pressure gas cylinder.

[0028] Furthermore, the internal gas pressure of the high-pressure gas storage cylinder is 12-15Mpa.

[0029] The advantages of the present invention compared with the prior art are:

[0030] The forest air treatment and oxygen and phytoncide gas storage system provided by the present invention integrates multiple functional modules such as air collection, purification, separation, and pressurized storage, thereby realizing efficient collection and purification of forest air, while retaining the oxygen and phytoncide gases therein, and storing them in a high-pressure form in a gas storage cylinder for subsequent use. The development and application of this system will provide people with healthy and natural air resources, which is of great significance for improving urban air quality and promoting human health.

[0033] The following is a further detailed description of a system and method for forest air treatment and storage of oxygen and phytoncide gas according to the present invention in conjunction with the accompanying drawings.

[0034] In conjunction with the accompanying drawings, a system for forest air treatment and storage of oxygen and phytoncide gas, the system comprising:

[0035] a) Air collection device for collecting fresh air from the forest environment;

[0036] The air in the forest is collected through an air collector, and an air inlet with adjustable wind speed is set on the air collector to meet the air collection needs of different forest environments;

[0037] b) an air filter connected to the air collection device, wherein the air filter adopts a multi-stage filtering arrangement, including a primary filter, a medium filter and a high efficiency filter, to remove impurities such as dust and particulate matter in the air;

[0038] c) an air compressor connected to the air filter and used to pressurize the filtered air;

[0039] The air compressor model is Muto air compressor, high-pressure oil-free industrial grade 380 volts, to avoid oil contamination of the treated gas;

[0040] d) a polymer sieve filter, connected to the air compressor, using a polymer sieve material with selective permeability, capable of efficiently separating nitrogen from the air while retaining oxygen and phytoncides;

[0041] The inner pore diameter of the polymer sieve is 0.3-10nm, and its specific surface area is 6200-6500m2 / g;

[0042] The polymer sieve filter is provided with an exhaust pipe for discharging the separated nitrogen;

[0043] e) a micro-pressure storage tank connected to the polymer sieve filter, used to temporarily store the separated oxygen and phytoncide gas and maintain a certain pressure;

[0044] The micro-pressure storage tank is made of 316L stainless steel, which is corrosion-resistant and high-pressure-resistant to ensure the safety and stability of the stored gas;

[0045] f) a gas compressor connected to the micro-pressure storage tank for further pressurizing the stored gas;

[0046] The gas compressor is a Yibang compressor, model HDB, to avoid oil pollution of the treated gas;

[0047] g) a high-pressure gas storage cylinder, connected to the gas compressor, for storing pressurized oxygen and phytoncide gas at high pressure, wherein the internal gas pressure is 12-15 MPa;

[0048] The high-pressure gas storage cylinder is made of SUS304 stainless steel, which has high strength and corrosion resistance to ensure the safety and stability of the stored gas;

[0049] The components of the system are connected in sequence to form a complete system for collecting, purifying, separating and pressurizing forest air for storage.

[0050] A method for the above system to process and store oxygen and phytoncide gas in forest air comprises the following steps:

[0051] Place the air collection device in the forest environment, open the air inlet, start collecting fresh air, and use the air collection device to collect fresh air from the forest;

[0052] The collected air is filtered through air filters at multiple stages to remove impurities such as dust and particulate matter;

[0053] Use an air compressor to pressurize the filtered air and control the pressure at 0.3-0.42Mpa;

[0054] Use a high molecular sieve filter to separate nitrogen from the pressurized air, retain oxygen and phytoncides, and discharge the separated nitrogen into the air;

[0055] The separated oxygen and phytoncide gases are stored in a micro-pressure storage tank with a controlled pressure of 0.1-0.15Mpa;

[0056] The gas stored in the micro-pressure storage tank is further pressurized by a gas compressor, and the pressurized gas is stored in a high-pressure gas storage cylinder, wherein the internal gas pressure of the high-pressure gas storage cylinder is 12-15Mpa.

[0057] In order to determine the best time period for collecting phytoncide gas, during the collection process, the National Engineering Laboratory for Volatile Organic Pollution Control Technology and Equipment of South China University of Technology was hired to conduct special tests on this. According to the national standards HJ644-2013 and HJ759-2015, the determination of volatile organic compounds in ambient air-adsorption tube sampling-thermal desorption / gas chromatography-mass spectrometry, and the dynamic adsorption-desorption performance test method of activated carbon for volatile organic compounds (VOCs) purification (VOCNEL003---2020), eucalyptol, α-pinene, β-pinene, β-myrcene, limonene, γ-terpinene, camphene, γ-elemene, dimethyl, and octatriene in many types of phytoncide in the primeval forests of Xinglong, Hainan were tested. The presence of the substances was detected, and after the separation and removal of nitrogen, the content per unit volume of the remaining gas increased significantly;

[0058] According to multiple tests and test analysis, it is finally determined that the separation and extraction time of oxygen and phytoncide in forest air should be from March to July and from November to December each year. This is because trees are relatively dormant from December to March, and from July to October, it is the peak period for various pests. The separated and extracted gases at this time will contain substances that are harmful to the human body. Therefore, it is concluded from the experiment that the separation and extraction time of oxygen and phytoncide in forest air should be from March to July and from November to December each year.

[0059] During the collection period, from sunrise in the morning to sunset in the evening, the light is strongest, the photosynthesis efficiency is highest, and the phytoncide gas and oxygen secreted by the trees are relatively abundant. Therefore, it is most appropriate to separate and extract oxygen and phytoncide gas during this period.

[0060] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
