Abstract: A biochemical analyzer is disclosed. The biochemical analyzer includes a detection disc sample feeding device, a detection disc device, an optical path detection device, and a temperature control device. The detection disc device includes a rotatable detection disc. The detection disc has a plurality of partitions, and each partition is correspondingly equipped with one chip to be detected. The detection disc is further provided with an optical limiting slot, and the optical limiting slot cooperates with a first limiting optocoupler located on a side face of the detection disc to monitor the number of rotations of the detection disc. Each partition of the detection disc may be equipped with one chip to be detected, and multiple chips can be detected in one operation by using the rotatable detection disc.

Abstract: An evaporative condenser radiating module for steam exhaust of a steam turbine comprises tube bundles and steam-water separating chambers. A steam-water separating chamber (4) between a section A and a section B, a section A downflow cooling section tube bundle (3), a section B downflow cooling section tube bundle (5), and a counter flow cooling section tube bundle (8) are disposes at the left side of a central steam-water separating chamber (7). An upper sealed space (10) of the steam-water separating chamber (4) between the section A and the section B is in communication with the central steam-water separating chamber (7) through the counter flow cooling section tube bundle (8). A lower sealed space of the steam-water separating chamber (4) between the section A and the section B is in communication with the central steam-water separating chamber (7) through the section B downflow cooling section tube bundle (5).
