Description
(54) ЭЛЕКТРОДУГОВОЙ НАГРЕВАТЕЛЬ ГАЗА(54) ELECTRIC GAS HEATER
Изобретение касаетс техники создани высокотемпературных газовых потоков, в частности устройств, преобразующих энергию электрической дуги в поток нагретого газа, которые используют дл термической обработйй материалов.The invention relates to the technique of creating high-temperature gas streams, in particular devices that convert the energy of an electric arc into a stream of heated gas, which are used for thermal processing of materials.
Известны электродуговые нагреватели газа, в которых электрическа дуга возбуждаетс между двум электродами, разметенными в канале 1.Electric arc gas heaters are known in which an electric arc is excited between two electrodes, spaced in channel 1.
Однако в таких нагревател х наблюдаетс -значительна эрози выходного электрода , особенно при нагревании газа, агрессивного по отношению к материалу электрода.However, in such heaters, there is a significant erosion of the output electrode, especially when the gas is heated, aggressive to the electrode material.
Известен также нагреватель газа, со держащий основной канал дл прохождени рабочего газа и по меньшей мере один дополнительный , на входе которых установлены стержневые электродь, а выходы объй динены общим соплом, причем электрод ос новного канала снабжен поджигающим электродом {2 .A gas heater is also known, which contains the main channel for the passage of the working gas and at least one additional, at the entrance of which a rod electrode is installed, and the outlets are connected by a common nozzle, and the electrode of the main channel is equipped with a firing electrode {2.
го характерны сложный процесс возбуждени электрической между основными эпектродами, oco6eifflo при использовании распределительных электродов.It is characterized by a complex process of electrical excitation between the main electrodes, oco6eifflo, using distribution electrodes.
Цель изобретени упрощение процесса возбуждени электрической дуги между основными электродами.The purpose of the invention is to simplify the process of driving an electric arc between the main electrodes.
Это достигаетс путем установки на вхде каждого из дополнительных каналов патрубка дл отвода газа,снабженногс затвором и системой отбора газа. Система отбора газа может быть выполнена в виде насоса Вентури, а в качестве затвора установлен электрогар аый клапан.This is achieved by installing on the inlet of each of the additional channels of the gas outlet pipe, provided with a gate and gas extraction system. The gas extraction system can be made in the form of a Venturi pump, and an electric valve is installed as a shutter.
На чертеже схематически изображен электродуговой нагреватепь газа с системой отбора газа.The drawing schematically shows an electric arc gas heater with a gas extraction system.
