На чертеже изображено предлагаемое изобретение, общий вид.The drawing shows the invention, a General view.

Аэрационное сооружение включает емкость 1, разделенную на секции, систему 2 аэрации, систе1ру 3 отопления, гибкую влагонепроницаемую оболочку 4 с дренажными окнами 5, снабженную поплавками 6 и прикрепленную к тросу 7.The aeration structure includes a tank 1, divided into sections, an aeration system 2, a heating system 3, a flexible moisture-proof shell 4 with drainage windows 5, equipped with floats 6 and attached to the cable 7.

Сооружение работает следующим образом.The construction works as follows.

При монтаже покрытия (на зимний период) гибкую влагонепроницаемую оболочку 4 'располагают по тросу 7, .крепят к оболочке 4 поплавки 6, опускают на водную поверхность, закрепляя поплавки 6 к конструкции емкости 1.When installing the coating (for the winter period), a flexible moisture-proof shell 4 'is placed along the cable 7, fasten the floats 6 to the shell 4, lower it onto the water surface, fixing the floats 6 to the tank structure 1.

Демонтаж покрытия (на летний период) производится в обратной последовательности.Dismantling of the coating (for the summer period) is carried out in the reverse order.

При технологическом процессе,проходящем в емкости 1, из системы 2 аэрации поступает газообразная смесь, например воздух, которая, насыщая обрабатываемую жидкость, выделяется 20 на водной поверхности, образовывает подушку, между водной поверхностью и влагонепроницаемой оболочкой 4, создавая подпор и поддерживая оболочку 4 в форме купола. 25During the technological process, which takes place in the tank 1, a gaseous mixture comes from the aeration system 2, for example, air, which saturates the liquid to be treated, is released 20 on the water surface, forms a cushion between the water surface and the moisture-proof casing 4, creating a backwater and supporting the casing 4 dome shape. 25

Оболочку 4 удерживают на плаву поплавки 6, закрепленные к конструкции емкости 1. Избыточную газообразную смесь удаляют через дренажные окна 5, выполненные в гибкой влагонепроницаемой оболочке 4. Обогрев сооружения осуществляется системой 3 отопления.The shell 4 is kept afloat by floats 6 fixed to the tank structure 1. Excess gaseous mixture is removed through drainage windows 5 made in a flexible moisture-proof shell 4. The building is heated by heating system 3.

The goal is achieved by the fact that in the aeratio structure, which includes a tank with walls and a coating, the aeration system and the heating system are divided into sections, the coating is made in the form of flexible moisture-proof shells with drainage windows fitted on cables and provided with floats fixed to the wall. The drawing shows the invention, offend the view. Aeration structure includes a tank 1, divided into sections. aeration system 2, heating system 1 1 3, flexible waterproof casing 4 with drainage windows 5, fitted with floats 6 and attached to the cable 7. The structure works as follows. When installing the coating (for the winter period), a flexible, moisture-proof casing 4 is placed along the cable 7, the floats 6 are attached to the casing 4, lowered onto the water surface, the floats are attached to the tank 1 structure. Dismantling the cover (for the summer period) is done in reverse order. During the technological process, which takes place in the tank 1, a gas mixture enters the system 2 air. For example, the air, which saturates the treated liquid and is released on the water surface, forms a pillow between the water surface and the moisture-proof casing 4, creating a backwater and supporting shell 4 in the shape of a dome. Shell 4 keeps floats b fixed to the structure of tank 1. Excess gaseous mixture is removed through drainage windows 5 made in a flexible moisture-proof shell 4. The weapon is heated by heating system 3.
