Description
Technical Field
The utility model relates to a deodorizing device technical field particularly, relates to a tertiary formula ion deodorizing device.
Background
The odor oxidation technology mainly generates a large amount of positive and negative oxygen ions with strong oxidizing property, can oxidize and decompose pollution odor factors such as methyl mercaptan, ethers, amines and the like in a very short time, opens chemical bonds of organic volatile gases, and finally generates stable and harmless micromolecules such as carbon dioxide, water and the like, thereby achieving the aim of purifying air.
The existing odor chemical oxidation technologies mainly comprise the following two technologies:
(1) plasma cracking technology: plasma is the fourth state of matter following a solid, liquid, gaseous state, and when the applied voltage reaches the ignition voltage of the gas, the gas is broken down, creating a mixture of electrons, various ions, atoms, and radicals. Although the electron temperature is high in the discharge process, the heavy particle temperature is low, and the whole system is in a low-temperature state, so that the system is called low-temperature plasma. The low-temperature plasma pollutant degradation utilizes the action of active particles such as high-energy electrons and free radicals and pollutants in exhaust gas, and pollutant molecules are decomposed in a very short time and then various subsequent reactions are carried out to achieve the purpose of decomposing pollutants.
The low-temperature plasma deodorization device is a technology for generating oxidizing plasma by arranging electrodes in equipment and ionizing air after high-voltage discharge, and is one of effective technical methods in domestic atmospheric pollution treatment at present due to the characteristics of easy high-efficiency decomposition of pollutant molecules, low energy consumption for treatment and the like
(2) UV photocatalysis technology: the UV photocatalysis is that a UV ultraviolet lamp tube is arranged in the device for irradiation and Ti0 is used for assistance2The technology has mild reaction conditions, rapid photolysis and CO as a product in the photocatalytic process as a catalyst2、H2O and others, and has wide application range, and organic substances such as hydrocarbon, alcohol, aldehyde, ketone and the like can be removed by UV photocatalysis.
The mechanism is mainly that the photocatalyst titanium dioxide absorbs photons, and hydroxyl free radicals (. OH) and active oxygen substances (. O, H) are generated on the surface of the photocatalyst titanium dioxide2O2) Wherein the hydroxyl radical (. OH) is a main active substance of the photocatalytic reaction, and plays a determining role in photocatalytic oxidation. The reaction energy of the hydroxyl free radical of 120kj/mol is higher than various chemical bond energies of organic matters, such as: C-C (83KJ/mol), C-H (99KJ/mol), C-N (73KJ/mol), C-O (84KJ/mol), H-O (111KJ/mol) and N-H (93KJ/mol), so that it can quickly and effectively decompose volatile organic compound, and can be added with other active oxygen organic substance (O, H)2O2) The synergistic effect of the components makes the sterilizing effect quicker.
However, the retention time of the odor of the chemical oxidation deodorization technology is generally controlled to be about 2s as determined by the technical requirements of the deodorization equipment, and under the condition of the retention time, the plasma cracking technology and the UV photocatalysis technology basically cannot completely degrade pollutants in the odor into CO2And H2The final stable forms of O and the like are mostly intermediate products or small molecular organic matters, and the treatment is not thorough. In addition, because of the gas production characteristic of deodorization, the reaction conditions of the chemical oxidation deodorization technology are normal temperature and normal pressure, under the conditions, the degradation effect on ammonia and hydrogen sulfide inorganic matters in the odor is poor, and actually, the odor contains ammonia and hydrogen sulfide with different concentrations, so that the chemical oxidation deodorization needs to be matched with other ammonia and hydrogen sulfide strengthening treatment processes.
In view of this, the present invention is especially provided.
