Claims (5)

1. Фильтр для очистки воды по меньшей мере в одной системе аварийного охлаждения атомной электростанции с реактором под защитной оболочкой, донная часть которой образует бассейн для сбора воды, полученной путем конденсации из пара, присутствующего под защитной оболочкой, установленный в водоеме с конденсатом и служащий для очистки воды, откачиваемой из бассейна и при необходимости подаваемой в форсунки системы аварийного охлаждения для охлаждения стержня реактора при недопустимом подъеме его температуры, выполненный в виде корпуса, имеющего по меньшей мере одну стенку (10) соответствующей цилиндрической формы с отверстиями, через которые вода может поступать снаружи внутрь корпуса, и соединенный посредством первого трубопровода (4) с всасывающим насосом, расположенным за пределами защитной оболочки реактора, а также со вторым трубопроводом (7) для подачи промывающей воды внутрь корпуса для промывки при необходимости стенки (10) фильтра путем пропускания сквозь нее воды изнутри наружу для удаления отложений фильтрата с наружной стороны стенки, отличающийся тем, что на стенке (10) фильтра имеются средства (17) разделения волокнистого пласта или слоя, образованного на наружной стороне стенки фильтра, на несколько частей, отделение которых по отдельности происходит значительно легче по сравнению с отделением сплошного волокнистого пласта.1. A filter for water purification in at least one emergency cooling system of a nuclear power plant with a reactor under a protective shell, the bottom of which forms a pool for collecting water obtained by condensation from the steam present under the protective shell, installed in a reservoir with condensate and used to purification of water pumped out of the pool and, if necessary, supplied to the nozzles of the emergency cooling system for cooling the reactor core with an unacceptable rise in its temperature, made in the form of a housing at least one wall (10) of a corresponding cylindrical shape with openings through which water can flow externally into the body, and connected via a first pipe (4) to a suction pump located outside the reactor containment shell, and also to a second pipe (7 ) for supplying washing water into the housing for washing, if necessary, the filter walls (10) by passing water from inside to outside to remove filtrate deposits from the outside of the wall, characterized in that On the filter bed (10) there are means (17) for separating the fibrous layer or layer formed on the outer side of the filter wall into several parts, the separation of which individually is much easier compared to the separation of a continuous fibrous layer. 2. Фильтр по п. 1, отличающийся тем, что указанные средства (17) разделения волокнистого пласта состоят из некоторого количества продольных ребер или подобных ребрам элементов (17), отстоящих друг от друга в окружном направлении и выступающих в радиальном. 2. The filter according to claim 1, characterized in that the said means (17) for separating the fibrous layer consist of a number of longitudinal ribs or elements similar to the ribs (17), spaced from each other in the circumferential direction and protruding radially. 3. Фильтр по п. 2, отличающийся тем, что ширина каждого ребра составляет 25-75%, желательно 40-60%, и предпочтительно около 50% диаметра или наибольшего размера поперечного сечения стенки (10) фильтра. 3. The filter according to claim 2, characterized in that the width of each rib is 25-75%, preferably 40-60%, and preferably about 50% of the diameter or the largest cross-sectional dimension of the filter wall (10). 4. Фильтр по пп. 1-3, отличающийся тем, что второй трубопровод состоит из трубы (7), которая в районе отверстия, расположенного концентрично стенке (10) фильтра, содержит средства (18) завихрения, выполненные в виде ряда криволинейных лопастей (20), установленных между трубой и коническим телом (19), центрально расположенным в ней, так что при протекании через кольцевой зазор между трубой и коническим телом вода приобретает вращение или закрутку для отбрасывания воды к стенке (10) фильтра. 4. The filter according to paragraphs. 1-3, characterized in that the second pipeline consists of a pipe (7), which in the region of the hole located concentrically to the filter wall (10) contains turbulence means (18) made in the form of a series of curved blades (20) installed between the pipe and a conical body (19) centrally located in it, so that when flowing through the annular gap between the pipe and the conical body, the water acquires rotation or twist to cast water to the filter wall (10). 5. Фильтр по пп. 1-4, отличающийся тем, что корпус закрыт на одном конце, например, верхнем, причем первый трубопровод (4) присоединен к противоположному концу, а трубопровод (7) для промывки соосно установлен в нем на некотором участке (4'). 5. The filter according to paragraphs. 1-4, characterized in that the housing is closed at one end, for example, the upper, and the first pipe (4) is attached to the opposite end, and the pipe (7) for flushing coaxially installed in it in a certain area (4 ').
