Complex local condensed water treatment device having a collecting, evaporating and feedback unit in a pumpless design of a steam cushion return (recirculation, feedback) system

摘要

The subject-matter of the invention is a complex local condensed water treatment device having a collecting, evaporating and feedback unit in a pumpless design of a steam cushion feedback system, in which an upper condensed water collecting and evaporating vessel (A), which has a common air chamber, is connected to the working vessel or vessels (B, C) via one or more connecting condensed water conducting (transfer) pipes(s) (3B, 3C) and check (nonreturn) valves (4B, 4C) arranged in the connecting condensed water conducting pipes (3B, 3C). The essence of the invention consists in that the upper condensed water collecting and evaporating vessel (A) is arranged above the working vessel(s) (B, C) in such a way that the condensed water conducting pipe(s) (3B, 3C), which connect(s) the upper condensed water collecting and evaporating vessel (A) to the working vessel(s) (B, C), is/are arranged jointly in the interior of the working vessel(s) (B, C) without a change in direction at right angles to the check valve(s) (4B, 4C).
