In the present invention, there is disclosed a reaction chamber RK 1 that is made of steel, has the shape of a cylindrical vessel (1), which is provided in its center with two pins (14), by means of which it is mounted within a positioning frame (16). A heating coil (18) is arranged around the cylindrical vessel body. Heat losses of systems are reduced by thermal insulation and an external thermal shield (19) of the total reaction chamber. The reactions take place in individual, separate reaction cells (A), (B), situated on opposite sides of the common cylindrical vessel (1). The cells (A) (B) are lined with thin-walled plastic cylinders (4) with a flange. Both the reaction cells (A), (B) are sealed by covers (2) made of stainless steel. In order to enable entry in the space of the cells (A), (B) and carrying out measurements, the covers (2) are each provided with five, specially fitted sockets (6, 7, 8, 9 a 10). Measuring transducers are connected through the mediation of a collecting cable (22) to a data recorder. The internal space of the reaction cells (A), (B) is separated by plastic perforated partitions (28) ensuring both separation of the measuring elements – such as electrodes (13), monitoring changes of pH factor in a liquid charge (26) from samples (27) being investigated, and stabilization of the samples (27) being investigated within a space. The stabilization is also ensured by means of a thin-walled, plastic wrapper around the samples (27). Dynamic action of reaction liquids (26) to the monitored samples (27) is secured by interval change in the apparatus position axis, and namely from horizontal and back, with a check ensured via a swing counter (34). The change in position is made by means of an arm of a pendulum mechanism (23), driven by an electric motor (24). The advantage of the proposed technical solution is that a structurally simple, material available, low cost maintenance and measurement non-demanding device can carry out long term measurements of physical processes as well as chemical reaction occurring between liquid charge (26) and investigated macro samples (27) under pressure and temperature conditions corresponding with in situ conditions, and namely under dynamic conditions of the system. |
