Claims (2)

электрически изолированы друг от друга по всей длине и сварены между собой на другом конце. Ток, проход щий по трубам в противоположных направлени х, конпентрируетс  лишь iB пристеночных сло х труб на поверхност х , обращенных друг « другу, поэтому внещн   поверхность наружной трубы и внутренн   поверхность внутренней трубы практически свободны от тока и совершенно безопасны . При прохождении тока в стальных стенках труб выдел етс  тепло, количество которого может просто и надежно регулироватьс  автоматически по температуре газового потока , температура которого на входе в газосборный пункт поддерживаетс  на уровне, равном или выше равновесной температуры гидратообразовани  в природном газе. Различное температурное удлинение труб при работе электронагревател  компенсируетс  перемещением частей внутренней трубы 1 относительно металлических втулок 7. Диэлектрическа  жидкость улучщает услови  теплообмена между трубами 1 -и 2 за счет ее лучщей теплопроводности по сравнению с воздухом. 5 10 15 20 25 Формула изобретени  1. Электронагреватель, преимущественно природного газа в трубопроводах, состо щий из соосно расположенных одна в другой металлических труб, наход щихс  в электроконтакте с одного конца и присоединенных другими концами к источнику электрического тока, отличающийс  тем, что, с целью «омпенсаций разности температурных деформаций труб, внутренн   труба выполнена из отдельных частей, которые подвижно соединены между собой посредством полых металлических втулок. electrically insulated from each other along the entire length and welded to each other at the other end. The current passing through the pipes in opposite directions only concentrates the iB sidewall layers of the pipes on the surfaces facing each other, therefore the outer surface of the outer pipe and the inner surface of the inner pipe are practically free from current and completely safe. With the passage of current in the steel walls of pipes, heat is generated, the amount of which can be easily and reliably controlled automatically by the temperature of the gas stream, whose temperature at the inlet to the gas collection point is maintained at or equal to the equilibrium hydrate formation temperature in natural gas. The various temperature lengthening of the pipes during the operation of the electric heater is compensated for by moving the parts of the inner pipe 1 relative to the metal sleeves 7. The dielectric fluid improves the conditions of heat exchange between the pipes 1 and 2 due to its better thermal conductivity compared to air. 5 10 15 20 25 The claims of the invention 1. An electric heater, mainly natural gas in pipelines, consisting of metal pipes coaxially arranged one inside the other and connected to one source of electricity and the other ends connected to a source of electrical current. In order to compensate for the difference in temperature deformation of pipes, the internal pipe is made of separate parts that are movably interconnected by means of hollow metal bushings. 2. Электронагреватель по п. 1, отличающийс  тем, что, с целью улучшени  теплообмена .между внутренней и наружной трубой, внутренн   труба выполнена с отверсти ми, а внутренн   полость электронагревател  заполнена диэлектрической теплопроводной жидкостью , например, трансформаторным маслом. Источники информации, прин тые во внимание при экспертизе. 1. Авторское свидетельство № 101973, М. Кл.2 A01G9/26, 1954.2. Electric heater according to claim 1, characterized in that, in order to improve heat exchange between the inner and outer tubes, the inner tube is made with openings, and the inner cavity of the electrical heater is filled with a dielectric heat-conducting fluid, such as transformer oil. Sources of information taken into account in the examination. 1. Copyright certificate № 101973, M. Cl.2 A01G9 / 26, 1954. 32 II Ч 5 6 II/32 II H 5 6 II /
