Description

Изобретение относится к области теплообменной техники и может быть использоваThe invention relates to the field of heat exchange technology and can be used

но в теплоэнергетике.but in the power system.

Цель изобретения — повышение ремонтопригодности путем упрощения замены гребенок.The purpose of the invention is to improve maintainability by simplifying the replacement of dies.

На фиг. 1 показано”устройство, общий вид; на фиг. 2 —^конструкция гребенки:FIG. 1 shows "the device, a general view; in fig. 2 - ^ comb design:

ί ·ί ·

'Устройство для; защиты, от эрозии содержит гребенки 1, установленные наклонно между, трубами 2-к примыкающие противоположными зубцам краями 4, имеющими упоры 5, к вертикальным стенкам газохода 7. Гребенки 1 направлены зубцами 3 вверх и свободно уложены на трубах 2 змеевиков, а упоры 5 расположены на верхней поверхности гребенок 1.'Device for; protection, against erosion contains combs 1, installed inclined between the pipes 2, adjacent edges 4 opposite the teeth, having stops 5, to the vertical walls of the flue 7. Combs 1 are directed upwards by teeth 3 and freely laid on the pipes 2 of the coils, and the stops 5 are located on the upper surface of the dies 1.

Работа устройства происходит следующим образом.The operation of the device is as follows.

Гребенки 1 опускаются между трубами 2 верхнего горизонтального ряда змеевика под углом к вертикальным стенкам 6 газохода 7 и упираются в них, причем устанавливаются свободно без дополнительного крепления. Благодаря наклону и собственх ному весу гребенки 1 фиксируются в установленном положении. Для избежания накладывания гребенок 1 одна на другую они снабжены с двух сторон упорами 5. 1 Для предотвращения появления неравномерности скорости потока и концентрации золы по сечению газохода 7 гребенки 1 размещаются с шагом между их серединами и верхним и нижним горизонтальными ; рядами труб 2, не превышающим восемь шагов между трубами 2. Замена изношенных гребенок 1 производится путем их извлечения из пространства между трубами 2 без демонтажа обшивки и обмуровки стенокCombs 1 are lowered between the pipes 2 of the upper horizontal row of the coil at an angle to the vertical walls 6 of the flue 7 and abut against them, and are installed freely without additional fastening. Due to the slope and self-weight of the comb 1 are fixed in the set position. To avoid overlapping of the dies 1 against each other, they are provided with lugs 5 on both sides. 1 To prevent uneven flow rates and ash concentrations in the cross section of the flue 7, combs 1 are placed with a pitch between their middle and upper and lower horizontal ; rows of pipes 2 not exceeding eight steps between pipes 2. Replacing worn combs 1 is made by removing them from the space between pipes 2 without dismantling the casing and lining the walls
