Description
PHOTOCATALYTIC OXIDATION EXHAUST GAS PURIFIER FIELD OF THE INVENTION
[0001] The invention belongs to the field of devices for industrial exhaust gas treatment, and relates to an exhaust gas purifier, and more particularly to an efficient photocatalytic oxidation exhaust gas purifier.
BACKGROUND
[0002] Most of the industrial exhaust gases are volatile organic gases, which consist of the substances harmful to the human body and are mostly gas-phase pollutants composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, halogen and other elements. In terms of chemical structure, the industrial exhaust gases generally have odor molecules having the characteristic of stimulating human’s olfaction, due to the residual electrons.
[0003] At present, exhaust gas treatment technology mainly includes physical and chemical treatment. The commonly used physical method is to absorb the exhaust gas through activated carbon adsorption or leaching by acid or base solutions, while chemical method is to wash or incinerate the exhaust gas. However, these two methods often cannot purify the exhaust gas completely or would produce secondary pollutants and a large number of dust, and especially, large amounts of waste water would be generated and need to be processed after washing and absorption. Recently, a treatment method using ultraviolet ray has been developed, of which the current treatment processes have the following shortcomings, i.e., lack of diversification, low treatment efficiency, and incomplete treatment.
BRIEF SUMMARY OF THE INVENTION
[0004] In view of this, the technical problem to be solved of the present invention is to provide an efficient photocatalytic oxidation exhaust gas purifier with reasonable structure design, which can improve the efficiency of exhaust gas treatment effectively, treat exhaust gas completely, avoid secondary pollutants effectively, and has the advantages of strong adaptability, stable operation, low cost, compact structure, small size, convenience for transportation and installation, as well as extremely high value-in-use.
[0005] The invention is realized as follow: an efficient photocatalytic oxidation exhaust gas purifier comprises a housing, an air inlet arranged at the left end of the housing, an air outlet arranged at the right end of the housing, and an ultraviolet generator, an ion generator and a plurality of photocatalytic screens inside the housing, a controller arranged on the housing and electrically connected to the ultraviolet generator and the ion generator, and a funnel-shaped receiving groove provided at the bottom of the housing, wherein a discharge port is arranged in the center of the receiving groove.
[0006] The ultraviolet generator is composed of an ultraviolet tube using Bentax technology and a separate regulator.
[0007] The ultraviolet ray emitted by the ultraviolet generator consists mainly of short-wave ultraviolet ray with a wavelength of about 200 nm.
[0008] A filter is provided inside the housing.
[0009] On the photocatalytic networks are provided with nano-sized titanium dioxide.
[0010] The ultraviolet generator and the ion generator are arranged uniformly in the space separated by the photocatalytic screens inside the housing. The ion generator can be a Bentax ion generator.
[0011] The invention has the beneficial effects as follow: an efficient photocatalytic oxidation exhaust gas purifier comprises a housing, an air inlet arranged at the left end of the housing and an air outlet arranged at the right end of the housing, and an ultraviolet generator inside the housing can generate ultraviolet ray irradiated within the housing and is composed of an ultraviolet tube using Bentax technology and a separate regulator. The lifetime of the ultraviolet tube can be effectively increased by using Bentax technology, and the ultraviolet ray emitted by the ultraviolet generator consists mainly of short-wave ultraviolet ray with a wavelength of about 200 nm. The ultraviolet generator is modulated to emit short-wave ultraviolet with a wavelength of about 200 nm, which has high energy to ionize the oxygen at the room temperature to form ion groups. The ion groups interact with the organic gas molecules to destroy the chemical bonds in the organic gas molecules, and finally produce stable carbon dioxide, water and other small molecules, which can effectively improve the decomposition efficiency of organic gases. A Bentax ion generator inside the housing can generate a large number of both positive and negative ions in the housing which can be combined with various molecules to achieve the aims of sterilization and deodorization. A plurality of photocatalytic screens in the housing with nanosized titanium dioxide can reduce the airflow velocity, prolong the contact time, and improve the efficiency of catalytic reaction. The ultraviolet generator and the Bentax ion generator are arranged uniformly in the space separated by the photocatalytic screens inside the housing, which can effectively increase the intensity of ultraviolet radiation and the concentration of both positive and negative ions in the housing, so that all the photocatalytic screens can be irradiated by ultraviolet with sufficient intensity. On the top of the housing is provided with a controller which is electrically connected to the ultraviolet generator and the Bentax ion generator. The controller is utilized to adjust the number of ultraviolet generators and Bentax ion generators which are working based on the exhaust gas throughput, which can not only guarantee the effect of exhaust gas treatment but also save energy. At the bottom of the housing is provided with a funnel-shaped receiving groove to receive the produced liquid water and dust. In the center of the receiving groove is arranged with a discharge port, which can facilitate cleaning without stopping the device. Inside the housing is provided with a filter to filter exhaust gas.
[0012] In general, the invention has the advantages of reasonable structure design, effective improvement of the efficiency of exhaust gas treatment, totally complete treatment of exhaust gas treatment, effective avoidance of secondary pollutants, strong adaptability, stable operation, low cost, compact structure, small size, convenience for transportation and installation, and extremely high use value.
