(54) УСТРОЙСТВО ЗАЩИТЫ ЗМЕЕВИКОВЫХ ТРУБ КОТЛОВ ОТ ИЗНОСА(54) DEVICE FOR PROTECTION OF BOILER COIL PIPES FROM WEAR
Изобретение относитс к устройствам защиты труб котлов от износа и может быть использовано в котлостроении.This invention relates to devices for protecting pipes of boilers from wear and can be used in boiler building.
Известны устройства защиты стлеевиковых труб от эррозионного износа, содержащие горизонтальную гребенку, зубь КОТОРОЙ расположены над гибамиKnown protection device stleyevikovy pipes from erosion wear, containing a horizontal comb, the teeth are located above the bends
труб 1. . .pipes 1.. .
Недостатком описанного устройства вл етс низка эффективность и сложность монтажа и ремонта, св занна с их чисткой и заменой.The disadvantage of the described device is the low efficiency and complexity of installation and repair associated with their cleaning and replacement.
Целью насто щего изобретени вл етс повышение эффективности и упрощенй монтажа.The object of the present invention is to increase the efficiency and simplify the installation.
Указанна иепь достигаетс тем, что устройство дополнительно содержит дисстанционирующие элементы, установленные между трубами и гребенкой, зубь которой выполнены сужающимис к их концам, причем гребенка может быть установлена с наклоном в сторону труб под углом, не превышающим 45.This degree is achieved by the fact that the device additionally contains dissolving elements installed between the pipes and the comb, the teeth of which are made tapering to their ends, and the comb can be installed inclined towards the pipes at an angle not exceeding 45.
На фиг. 1 изображена схема размещени защитных устройств; на фиг. 2 - поп ечный разрез средней гребенки; на фиг. 3 - вид сверху на среднюю гребенку .FIG. 1 shows the layout of the protective devices; in fig. 2 - cross-section of the middle comb; in fig. 3 is a top view of the middle comb.
Устройствосодержит гребенку 1, зубь 2 которой расположены над змеевИковьп 1и трубами 3. Дл креплени гребенки служат дисстанционируюшие элементы 4, установленные на змеевиковые трубы 3.The device contains a comb 1, the teeth of which 2 are located above the coils I and 1 and the tubes 3. To mount the comb, serve the dissociating elements 4 mounted on the coil tubes 3.
Гребенка 1 перекрывает свободное пространство между двум ветв ми змеевиковых труб и между трубами и стенкой. За счет формы зубьев 2, выполненных су жающимис , выравниваетс поле скоростей газов, проход щих через змеевиковые трубы 3, снижа тем самым эррозионный износ.Comb 1 covers the free space between the two branches of the coil pipes and between the pipes and the wall. Due to the shape of the teeth 2, which are made constricted, the velocity field of the gases passing through the coil pipes 3 is leveled, thereby reducing erosion wear.
