Description
Котел-утилизатор содержит вертикальный цилиндрический газоход 1 с патрубками 2 и 3 дл подвода и отвода газов, обрамленный экраном 4 из вертикальных труб 5 с нижним и верхним кольцевыми коллекторами 6 и 7, и снабженный радиально кольцевыми коллекторами 6 и 7, и снабженный радиально размещенными С-образными ширмами 8, трубы 9 которых подключен к трубам 5 экраном 4, а также установленный по оси газохода I полый цилиндрический вытеснитель 10 с нижним 11 и верхним 12 днищгми, выполнеными в виде конуса, которые подсоединены ПОДВОДЯ1ЧИМИ 13 Иотвод щими The waste-heat boiler contains a vertical cylindrical gas duct 1 with nozzles 2 and 3 for supplying and discharging gases, framed by a screen 4 of vertical pipes 5 with lower and upper annular collectors 6 and 7, and equipped with radially annular collectors 6 and 7, and equipped with radially located C -shaped screens 8, pipes 9 of which are connected to pipes 5 by screen 4, as well as a hollow cylindrical displacer 10 installed along the axis of the flue I with the bottom 11 and the top 12 bottoms, are made in the form of a cone, which are connected
14 трубопроводами к нижнему 6 и верхне 7 коллекторам.14 pipelines to the bottom 6 and top 7 collectors.
алтеснитель 10 снабжен установленной в его полости 15 цилиндрической перегородкой 16. К коллекторам 7 и 8 подсоединены соответственно.трубы 17 и 18 дл подвода и отвода охлаждающей среды. Altener 10 is provided with a cylindrical partition 16 installed in its cavity 15. Connected to the manifolds 7 and 8 are pipes 17 and 18 for supplying and discharging the cooling medium.
Котел-утилизатор работает следующим образом. The waste heat boiler works as follows.
Гор чие газы поступают в газоход 1 через патрубок 2, проход т вдоль труб 5 экрана 4, труб 9 ttmpM 8 и стенох вытеснител 10, охлаждаютс и через патрубок 3 ваход т из котлаутилизатора .Hot gases enter the gas duct 1 through the pipe 2, pass along the pipes 5 of the screen 4, the pipes 9 ttmpM 8 and the walls of the propellant 10, are cooled and through the pipe 3 enter the boiler from the boiler.
Охлаждающа среда (вода) поступает по трубам 17 в кольцевой нижний коллектор 6, из которого одна часть воды по трубопроводам 13 направл етс в вытеснитель 10, а ДРУга - в трубы 5 экрана 4 и трубы 9 ширм 8.Cooling medium (water) flows through pipes 17 into an annular lower collector 6, from which one part of water flows through pipelines 13 to the displacer 10, and Drug to the pipes 5 of the screen 4 and pipes 9 of the screens 8.
За счет тепла газоввода частично испар етс и образующа с паровод на смесь собираетс в верхи&м коллектора 7 и по трубам 18 выводитс из кЬтла-утилизатора..Due to the heat of the gas supply, it is partially evaporated and the resulting steam generator into the mixture is collected in the tops of the & m collector 7 and discharged through pipes 18 from the waste heat exchanger.
Циркул ци охлаждающей среды осуществл етс по замкнутому контуру естественной циркул ции, в котррглй вход т ширмы 8, экран 4 и вытеснитель 10. Выполнение, вытеснител 10 с конусными днищами 11 и 12, ве5 дины которых подключены подвод щими 13 и отвод щими 14 трубопроводами,.к ниж иему 6 и верхнему 7 коллекторам , обеспечивает надежное охлаждение стенок вытеснител 10 и участие посладних в охлаждении газов, что повышает наде хность и эффективность -котлаутилизатора .The cooling medium circulates along a closed loop of natural circulation, which includes screens 8, screen 4, and a displacer 10. Execution, displacer 10 with conical bottoms 11 and 12, the bottoms of which are connected by inlet 13 and outlet 14 pipes, . To the bottom 6 and the upper 7 collectors, provides reliable cooling of the walls of the displacer 10 and the participation of coolants in the cooling of gases, which increases the reliability and efficiency of the heat exchanger.
Размещение в полости 15 вытесните .л 10 цилиндрической перегородки 16 упор дочивает движение воды в вытеснителе 10, ликвидирует расслоение паровод ной смеси, что также приводит к повыдению надежности за счет лучшего охлаждени стенок вытеснител 10.Placement in the cavity 15 displace. 10 the cylindrical partition 16 arranges the movement of water in the displacer 10, eliminates the separation of the steam-water mixture, which also leads to increased reliability due to better cooling of the walls of the displacer 10.
Применение предлагаемого устройства позвол ет увеличить срок службы котла-утилизатора, сократить врем на ремонт и снизить капитальные затраты на изготовление.The application of the proposed device allows to increase the service life of the recovery boiler, reduce repair time and reduce capital costs for manufacturing.
