Area of techniques

The invention is connected with the water steam separator with double-membrane thermal element controlled by thermodynamic resistance

State of the art

There are a lot of various preparations for separating of water steam. The construction of thermal flange separator of water steam is described in the Czech utility model No. 123830. Solution of ^" thermal water steam separator is described in another Czech utility model NO. 9798 and construction between the flange condensate separator body is described in the Czech utility model No. 10896. The solution of thermally controlled membrane control of water steam separator with reduced hydrodynamic resistance is described in the Slovak patent No. 281654.

Object of the invention

The object of the mentioned invention is that the separator contains the double- membrane thermal element that is inserted between two halves of the separator body which are then connected by screws. The double-membrane thermal element consists of the carrying part, binding ring situated between two membranes in which an opening for liquid and nuts closing this double-membrane thermal element is made. The double-membrane thermal element is exchangeable and by its dimensions it is identical into all dimensions of separators of this line from DN-15 to DN-50. Condensate arriving from the separator enters the condensation chamber and then feeding channels around the double-membrane thermal element into the outlet part of the separator. Steam arrives in the inlet part of the separator where it encounters

membrane behind which there is a volatile liquid that develops pressure after heating and closes both inlet and outlet of the separator whereby outlet is oriented on the opposite side which means that steam that comes through from the inlet;- through channels to the outlet does not get out due to the fact that both inlet and outlet are closed simultaneously using the double-membrane thermal element which results in delayed arrival of steam to the outlet which fact is ensured by channels through which steam must pass to the outlet part of the separator. The separator enables installation in optional working position thanks to its construction which means that its functionality does not change due to authenticity of both inlet and outlet and therefore a direction of media flow need not be marked. Thanks to its definition of saddleback part from membrane, it is capable of working under low pressure 0,05 MPa, as well, however, with substantially lower mass output. The maximum temperature of usability of the separator is 260 ⁰ C, with a direct impact of temperature on membranes.

Overview of pictures on drawings

The separator in installed state is shown in fig. 1. The double-membrane thermal element is shown in fig. 2.

Example of realization

The separator contains the double-membrane thermal element 3 inserted between the left side I of the separator and the right side 2 of the separator which sides contain condensation chamber 9 whereby both sides 1_, 2 are then connected with screws. The double-membrane thermal element 3_ consists of the carrying part JJ2, binding ring ϋ with opening j_3 for liquid passing between the two membranes H and nut K) that closes this double-membrane thermal element 3_, The double-membrane thermal element 3_ is exchangeable and by its dimensions identical into all dimensions of separators of this line from DN-15 to DN-50.' Condensate arriving from the separator enters the condensation chamber 9 and then feeding channels 5, 6, 7 around the

thermal element 3 into the outlet part of the separator. Steam arrives in the inlet part of the separator where it encounters membrane 14 behind which there is a volatile liquid that forms pressure after heating and closes both inlet 4 and outlet % of the separator whereby outlet 8 is oriented on the opposite side which means that steam that comes through from the inlet 4 through channels 5, 6, 7 to the outlet 8 does not get out due to the fact that both inlet 4 and outlet 8 are closed simultaneously using the double- membrane thermal element 3_ which results in delayed arrival of steam _. 8 to the outlet which fact is ensured by channels 5_, 6, 7 through which steam must pass to the outlet part of the separator. The separator enables installation in optional working position thanks its construction which means that its functionality does not change due to authenticity of both inlet 4_and outlet 8 and therefore a direction of media flow need not be marked. Thanks to its definition of saddleback part from membrane 14 it is capable of working under low pressure 0,05 MPa, as well, however, with substantially lower mass output. The maximum temperature of usability of the separator is 260 ⁰ C at a direct impact of temperature on membranes 14.
