Technical field
The utility model relates to a kind of indoor self-purification self-checking unit, belongs to photochemistry self-purification experimental apparatus.
Background technology
At present, the pollution of room air, is free, accumulative process to the harm of human body, especially serious to old man, children, pregnant woman's harm.Existing existing report: children cause leukaemia, fetal death, deformity youngster, old man and obtain not bright its dispirited, the respiratory disease etc. wonderfully of cancer, family circle.At present the most authoritative report is from Pekinese Yi Jia hospital.In the leukemia of children case of accepting for medical treatment at them, 9% is relevant with house decoration.The < < covil construction indoor environmental pollution that country promulgates is controlled in standard > >, has also expressly provided several poisonous, harmful gases (benzene, formaldehyde, radon, ammonia, TVOC) that must detect.So the detection of indoor toxic and harmful and removal are the emphasis of building human health environment all the time.Existing market has various eliminating smell agents, disinfectant.But these products are all to adopt chemical way to process, and in fact with strong oxidizer, airborne oxidation operation is fallen exactly, but whether these class methods can produce secondary pollution, and existing data can't be got rid of this worry.Also have expert to think that environmental protection concept completely should be to adopt plant to absorb the method for decomposing, and found that some plants have different Adsorption and decomposition effects to different harmful gases, but it is slow that the feature of plant action is speed, long processing period is applied and is also encountered awkwardness in reality.Therefore, for the method for current chemical harnessing, mainly contain two and query greatly: the one, validity; The 2nd, secondary pollution problem.
Photochemistry and photocatalytic oxidation are to study at present a more high-level oxidation technology.So-called light-catalyzed reaction, the chemical reaction carrying out under the effect of light exactly.Photochemical reaction needs the electromagnetic radiation of molecule absorption specific wavelength, is excited to produce molecular-excited state, then chemical reaction can occur and generate new material, or become the middle chemical product that causes thermal response.Photochemically reactive energy of activation derives from the energy of photon, and in the utilization of sun power, photoelectric conversion and photochemical transformation are very active research fields always.Photocatalysis oxidation technique utilizes optical excitation oxidation by O 2, H 2o 2in oxygenant, combine with optical radiation.Institute uses up and is mainly ultraviolet light, comprises UV-H 2o 2, UV-O 2etc. technique, can be for the treatment of CHCl in sewage 3, CCl 4, the hard-degraded substance such as polychlorinated biphenyl.Calendar year 2001, first the people such as R.Asahi find the TiO of N element doping 2the absorption band edge red shift of nano-crystal film, to visible-range, this means that making full use of sunshine becomes possibility.At present, along with rise and the photocatalysis technology of nanometer technology are rapid in the development of the aspect applied researcies such as environmental protection, health care, organic synthesis, the research of the photocatalyst of nanometer scale, has become one of most active research field in the world.Actual people have applied sunshine and have participated in preparation of photochemical coating etc., illustrate that photocatalysis can generation effect to environment.But do not utilize the relevant report of photocatalysis treatment toxic and harmful.
Summary of the invention
The utility model provides a kind of indoor self-purification self-checking unit, and utilizing the toxic and harmful in photocatalytic degradation of indoor environment is target, optimizes indoor environment; Gaseous environment in simulating chamber, detects self-purification in indoor environment.
The utility model is realized with following technical scheme: a kind of indoor self-purification analogue experiment installation, it comprises the casing of sealing, one side on casing is provided with air intake opening, another side is provided with gas outlet, in the center of casing, be provided with for placing the double-deck cold-trap of hollow of light source, at the openend of the double-deck cold-trap of hollow, be provided with water inlet and water delivering orifice; Also comprising lives is arranged on the brassboard for application room to be measured coating for wall surface used in casing.
The utility model enters in casing by the gas of the environment to be measured of collection, utilizes light source to eliminate harmful gas as the indoor self-purification function generation photooxidation reaction of daylight lamp, then gas after photooxidation reaction is sent and is detected from gas outlet.
The beneficial effects of the utility model are: simple in structure, easy for operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, structure of the present utility model is further illustrated.
