Abstract
The invention relates to the field of instrumentation and, in particular, to gas-discharge devices for purifying potable and wastewater and sterilizing materials and equipment using gas-discharge ultraviolet radiation. The technical result of the invention is the creation of a fairly simple and reliable source of ultraviolet radiation which allows an ultraviolet lamp to operate optimally. The technical result is achieved in that the microwave gas-discharge source of ultraviolet radiation contains a microwave frequency generator connected to an external element, an internal element, and a gas-filled volume. The internal element consists of a metal cylindrical rod with a mirrored surface that reflects ultraviolet radiation. The external element is disposed coaxially with the internal element and consists of a metallic latticework that is cylindrical in shape, and the gas-filled volume consists of two coaxial cylindrical quartz tubes (a cylindrical toroid ring) disposed coaxially with the internal element.

Предшествующий уровень техники State of the art
В последнее время разрабатываются газоразрядные источники УФ излучения, в которых для возбуждения газовой среды используется СВЧ генератор. Указанные системы, использующие безэлектродные лампы обладают целым рядом преимуществ по сравнению с традиционными электродными системами: сравнительно малые габариты и вес; дешевизна источников питания; отсутствие загрязнения внутренних стенок в результате распыления электродов и др. Recently, gas-discharge sources of UV radiation have been developed, in which a microwave generator is used to excite a gaseous medium. These systems using electrodeless lamps have a number of advantages compared to traditional electrode systems: relatively small dimensions and weight; low cost of power sources; lack of contamination of the inner walls as a result of atomization of electrodes, etc.
Известно устройство, содержащее СВЧ генератор, внутренний и внешний проводящие протяженные элементы, соединенные непосредственно с магнетроном, газоразрядную лампу, расположенную между первым и вторым элементами и заполненную аргоном и парами ртути. Разрядная лампа представляет собой диэлектрический цилиндрический тороид, вдоль оси которого располагается внутренний
элемент (металлический цилиндрический стержень). Поверхность внутреннего элемента не является зеркальной (RU 2236060 С1, 10.09.2004). A device is known that contains a microwave generator, internal and external conductive extended elements connected directly to a magnetron, a gas discharge lamp located between the first and second elements and filled with argon and mercury vapor. The discharge lamp is a dielectric cylindrical toroid, along the axis of which there is an internal element (metal cylindrical rod). The surface of the inner element is not mirrored (RU 2236060 C1, 09/10/2004).
Недостатком известного устройства является отсутствие зеркальной поверхности у внутреннего элемента, что не позволяет увеличить интенсивность УФ излучения. A disadvantage of the known device is the lack of a mirror surface of the internal element, which does not allow to increase the intensity of UV radiation.

Варианты осуществления предложения Options for implementing the proposal
Микроволновой газоразрядный источник УФ излучения содержит СВЧ генератор 5 (в частности магнетрон и питание к нему от стандартной бытовой печи г=2,45гГц, Ν=1κΒτ), соединенные с ним внешний элемент 1 , внутренний элемент 3 и газонаполненную емкость 2. Внутренний элемент 3 выполнен в виде цилиндрического металлического стержня с зеркальной, отражающей УФ излучение поверхностью. Внешний элемент 1 установлен соосно с внутреннем элементом 3 и выполнен в виде металлической сетки цилиндрической формы. Газонаполненная емкость 2 выполнена из двух соосных цилиндрических кварцевых трубок (цилиндрический тороид), расположена соосно с внутренним элементом 1 и заполнена аргоном и парами ртути. The microwave gas-discharge source of UV radiation contains a microwave generator 5 (in particular, a magnetron and power to it from a standard household oven g = 2.45 GHz, Ν = 1κΒτ), an external element 1, an internal element 3, and a gas-filled container 2 connected to it. Internal element 3 made in the form of a cylindrical metal rod with a mirror surface reflecting UV radiation. The outer element 1 is mounted coaxially with the inner element 3 and is made in the form of a metal mesh of a cylindrical shape. The gas-filled container 2 is made of two coaxial cylindrical quartz tubes (cylindrical toroid), is located coaxially with the inner element 1 and is filled with argon and mercury vapor.
Работа устройства осуществляется следующим образом.
Генератор 5 (магнетрон) при подключении к сети генерирует микроволновое излучение с частотой 2,45 гГц и мощностью N = 1кВт. Это излучение ионизирует газовую среду в емкости 2, которая начинает излучать УФ излучение на длине волны 254 нм. Зеркальная поверхность внутреннего элемента 3 отражает УФ лучи и увеличивает общую мощность, излучаемую внешней поверхностью тороидальной лампы. The operation of the device is as follows. Generator 5 (magnetron) when connected to the network generates microwave radiation with a frequency of 2.45 GHz and a power of N = 1 kW. This radiation ionizes the gas medium in the tank 2, which begins to emit UV radiation at a wavelength of 254 nm. The mirror surface of the inner element 3 reflects UV rays and increases the total power emitted by the outer surface of the toroidal lamp.
