5), adsorbent equipment is with air flow arrangement, with the suction of the gas outside adsorbent equipment adsorbent equipment, with the tea leaf residual effect; Aqua Folium Camelliae sinensis atomizes in atomising device, directly acts on airborne formaldehyde particle.
In technique scheme, in step 1), tealeaves is pulverized and is 0.3mm-0.8mm.
In technique scheme, step 2) in, infusion of tea is 3 times, each 15 minutes.
Above-mentioned preferred technical scheme, tealeaves are used 80 degree-90 degree water soakings.
The present invention utilize the activating components such as the alkaloid that contains in tealeaves, Tea Polyphenols, amino acid can with the formolite reaction principle, the materials such as use tealeaves pure natural substance PARA FORMALDEHYDE PRILLS(91,95) are removed, harmlessly do not produce secondary pollution, the removal effect of formaldehyde is obvious, formaldehyde environment for 1ppm, can reach 85% clearance rate by PARA FORMALDEHYDE PRILLS(91,95) in 8 hours, effectively raise the value of tealeaves, improve the development prospect of Tea Industry.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of equipment used herein.
The specific embodiment
Below in conjunction with accompanying drawing of the present invention, technical scheme of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
A kind of extract air purification method in tealeaves comprises the steps:
1), tealeaves carried out particle pulverize, pulverize the broken end into 0.3mm-0.8mm, the best is 0.4mm;
2), the tealeaves after pulverizing that step 1) is obtained is placed in steeping tank, water fully soaks, and uses 80 degree-90 degree water soakings, soaks each 15 minutes 3 times.
3), filter, leave and take Aqua Folium Camelliae sinensis and tea leaf residual after immersion;
4), tea leaf residual is placed in adsorbent equipment; Aqua Folium Camelliae sinensis is placed in atomising device;
5), adsorbent equipment is with air flow arrangement, with the suction of the gas outside adsorbent equipment adsorbent equipment, with the tea leaf residual effect; Aqua Folium Camelliae sinensis atomizes in atomising device, directly acts on airborne formaldehyde particle.
Operative installations of the present invention is: steeping tank 1, atomizer 2, adsorbent equipment 3, the air flow arrangement that arranges in adsorbent equipment are positioned at the air outlet place of adsorbent equipment, the Bas Discharged after filtering by tealeaves.Tealeaves drops into above steeping tank, and wherein, steeping tank is the tank that the bottom communicates, the bottom has and highly is the gap 15 of 0.5cm-1cm, and half is soak zone 11, and half is storage area 12, the preferred ration of division is 1/3 to be soak zone, and 2/3 is the storage area, is positioned at the storage area side to set out the mouth of a river 13; Adsorbent equipment is connected to below steeping tank, adsorbent equipment and steeping tank are cut apart by the loose joint sheet, after infusion of tea is complete, stir loose joint sheet 14, tealeaves drops to the adsorbent equipment adsorption zone, in adsorbent equipment, be divided into air inlet area, adsorption zone 31, exhaust area by network structure 32, below exhaust area, air flow arrangement 4 be set, as unidirectional exhaust blower, can accelerate the adsorption zone that passes through of contaminated air, with tealeaves broken end reaction; The Aqua Folium Camelliae sinensis of steeping tank gained is by the processing that atomizes of existing atomizer.
the mechanism of utilization of the present invention is: the absorption of tealeaves belongs to the multilayer absorption of " S " type, tealeaves is porous solid, the shape and structure that appearance is not only arranged, and complicated inner surface microcellular structure arranged, these microcellular structures are similar to many irregular capillaries, after the Van der Waals force of molecule on capillary wall produces suction-operated, one adsorption layer is arranged on hole wall, the present invention is broken last with the tealeaves that tealeaves is broken into certain size, the external surface area that has increased tealeaves is inappreciable with respect to internal surface area, a large amount of molecules is distributing on interior surface layers, it is subjected to the attraction of the outer molecule of the large fourth of attraction of internal layer molecule, be subjected to force unbalance, and the air flow arrangement by adsorbent equipment in adsorbent equipment, the contaminated air that sucks at a high speed is between tealeaves broken end, contact with tealeaves, the tealeaves surface is held because of discontinuity equalization and is being accumulate quite high surface energy, when the gas molecule collision of motion is to the consubstantiality inner surface around, wherein a part of molecule concentrates on superficial layer, absorption has namely occured, and with the material that contains palmitic acid equimolecular quantity macrostructure complexity in tealeaves, these materials all have very strong absorption property, the adsorbance of testing the adsorbance specific activity charcoal that shows tealeaves is few, tealeaves is different to the adsorbance of different compounds, adsorbance to high boiling substance is larger, the polar group of medium and high-grade tealeaves is more, adsorbance than low-grade tea is large.
Owing to containing the Multiple components such as alkaloid, Tea Polyphenols, amino acid in tealeaves, these polyphenols belong to contracting platform tannin mostly, because its major part is dissolved in water, so be called again water-soluble tannin again.It is comprised of flavanol compound (catechin), anthocyan (leucoanthocyanidin and anthocyanidin), anthoxanthins (flavones and flavonols), contracting acid and depside.Except phenolic acid and depside, other several compounds are due to the basic structure that all has 2-phenyl benzopyrans, so can be referred to as flavonoids.What wherein quantity was maximum is that flavanol compound is catechin, is about 70～80% of Polyphenols total amount in tealeaves; Alkaloid and amino acid are all nitrogen-containing compounds, and alkaloid refers to the alkaline nitrogenous chemicals of (being mainly plant) in organism, and the alkaloid in tealeaves mainly is divided into two types of Purine bases and pyrimidine bases.And the amino acid in tealeaves has 26 kinds by extraction, purifying, separation, evaluation, and wherein 20 kinds is the amino acid of constitutive protein matter, and 6 kinds is non-protein amino acid.A fairly large number of is theanine (more than 50%), when next is the formaldehyde such as arginine, serine and Tea Polyphenols reaction, phenolic hydroxyl group in Tea Polyphenols generates stable compound from separating the negative oxygen ion and the formaldehyde that generate, when formaldehyde and amino acid reaction, carbonyl in formaldehyde and amino acid whose in N-H key generation addition reaction, and then the stable product of dehydration generation, thereby utilize the Aqua Folium Camelliae sinensis atomizing can effectively eliminate/reduce formaldehyde, reach the purpose that purifies air.
The present invention's apparatus principle can be used as family and uses, and also can be used as large-scale air cleaning and uses.
[0018] the above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by described protection domain with claim.
