Description
Technical Field
The utility model discloses ultraviolet ray fluorescent tube technical field, concretely relates to high efficiency decomposes ultraviolet ray fluorescent tube that air produced ozone. Mainly, ozone is generated at the lamp tube with high efficiency, and the generated high-concentration ozone is dispersed into the space for disinfection and sterilization.
Background
Ozone, molecular formula O 3 Is oxygen (O) 2 ) The allotrope of (a). The ozone is light blue at normal temperature and has fishy smell. Ozone is formed by carrying an oxygen atom [ O ] by an oxygen molecule]The composition is in a temporary storage state, is unstable and has strong oxidizability. Therefore, the ozone is easy to decompose, the half-life period of the ozone in an unstable reference state is 22-25 minutes, the recession rate of one hour is 61%, the half-life period in a 1% ozone water solution is 16 minutes, and the half-life period is shorter as the temperature is higher and the humidity is higher. According to the induction and comparison of the international health organization on the sterilization efficacy, the killing effect on the escherichia coli is as follows from high to low in sequence: ozone generator>Hypochlorous acid>Chlorine dioxide>Silver ion>Hypochlorite of hypochlorous acid>Ferrate salt>Chloramine and ozone can be automatically decomposed into oxygen, so that secondary pollution to the environment is avoided.
The corona discharge method is the most commonly used method in the existing technical scheme for generating ozone, and a corona electric field is generated by using high voltage with certain frequency, so that oxygen molecules in the electric field generate electrochemical reaction to generate ozone. The disadvantage of this solution is thatThe generated electric field is not uniform, and is related to the voltage waveform of a power supply, the shape/distribution of electrodes and environmental conditions, and a part of components with energy enough to destroy molecular bonds of nitrogen to generate free nitrogen atoms so as to form oxynitride, including N, in the air exist on the high side of the electromagnetic field spectrum 2 O、NO、NO 2 、N 2 O 3 、N 2 O 4 And N 2 O 5 And the like, NOx for short, are harmful to human health and cause environmental pollution. NOx enters the deep lung of the body by breathing and can cause bronchitis or emphysema. NOx can also react photochemically with other pollutants in the atmosphere to form photochemical smog. Nitrogen dioxide is oxidized in the atmosphere to nitric acid, which is one of the causes of acid rain. Nitrogen dioxide also reduces ozone in the stratosphere, thereby increasing the amount of ultraviolet radiation reaching the earth. Some proposals propose to ionize oxygen under pure oxygen environment to generate ozone, although no nitride is generated, the cost is obviously improved, and the economic feasibility becomes a difficult problem. Patent publication No. CN103407968B also proposes a scheme of an ultraviolet photolysis ozone generator, which mainly comprises a shell, an air inlet pipe, an air outlet pipe and an ozone excitation device positioned in the shell. The spiral air channel surrounding the ozone excitation equipment is arranged in the shell, so that the gas entering the shell can move towards the air outlet pipe along the air channel, the irradiation time of the gas receiving the ozone excitation equipment is prolonged, and the concentration of ozone is increased. Although the mode of adopting ultraviolet ray does not produce nitride, adopt spiral air flue, the ozone that produces can decompose in overlength air flue because of its unstability to complicated structure, the processing degree of difficulty improves, adopts the shell of lightproof not convenient to daily use and later maintenance. The patent publication No. CN108100999A also proposes an ozone generator, in which an upper block and a lower block are arranged in the housing to increase the length of the housing through which the air flow passes, and a plurality of ozone generators are connected in series to increase the concentration of ozone, so that the structure is complex, and a plurality of generators are required, which increases the cost. In addition, some technical solutions propose to add a catalytic unit to the ozone generator, which has the effect of locally enhancing the oxidizing power of the ozone, in fact exacerbating the ozone depletion rather than the ozone generation.
The above technical solutions generally have the following problems:
1. unstable, harmful by-products. Under the action of a high-voltage corona electric field, the byproduct is that nitrogen in the air is decomposed to generate harmful gas; if pure oxygen is used as the gas source, the use cost is significantly increased.
2. The structure is complex and the efficiency is low. Although the ultraviolet lamp is used in the existing photolysis air scheme, on the premise that air is adopted as an air source, the length of an effective air passage and the contact area are improved by increasing the structural complexity, ozone is unstable, self-decomposition can be carried out in the overlong air passage, the comprehensive obtained effect is high in cost, low in efficiency, and the structure is too complex.
3. In the ozone generation scheme, the purpose of adding the catalyst is to locally enhance the ozone generation efficiency and enter the diffusion space to realize the dispersed disinfection, but not locally enhance the ozone oxidation efficiency and consume the ozone.
