Abstract

The invention provides a turbidity meter. The turbidity meter comprises a sample tank, a light source and a detector and a control system, and further comprises a heating system and a cooling system, wherein the light source and the detector are fixed on the two sides of the sample tank respectively; the control system is used for controlling the light source and the detector; the heating system is used for heating a sample to be heated; the heating system comprises a heating furnace for providing a sealed space and storing the sample tank; the heating furnace is further provided with an optical window for allowing light to pass through; the sample tank comprises a sample tank main body made of a high-temperature-resisting and corrosion-resisting material, and a window plate which is made of a high-temperature-resisting and corrosion-resisting material and through which visible light and near-infrared light pass; and the window plate is aligned to the optical window. The turbidity meter provided by the invention is additionally provided with the heating system and the cooling system, and the matched and designed sample tank, so that the turbidity of a sample with the temperature more than 200 DEG C and having corrosion is metered; and the turbidity meter has the advantages of good safety, strong operability, wide applicable range and the like.

Description

technical field [0001] The invention relates to the technical field of an instrument device for turbidity detection, in particular to a turbidity meter. Background technique [0002] Molten salt has been widely used in the fields of solar energy and nuclear energy due to its excellent thermophysical properties and heat transfer and storage properties. Lithium fluorine beryllium molten salt is used as the main coolant of the fourth-generation reactor-molten salt reactor, and its "cleanliness" means the concentration of insoluble impurities, which has an important impact on the operation of the reactor. Using HF-H 2 In the process of chemically purifying fluorine lithium beryllium molten salt, the corrosion product Ni in the molten salt will be 2+ , Fe 3+ , Cr 3+ The metal ions are reduced to metal powder, resulting in an increase in the concentration of insoluble substances in the molten salt during the operation of the stack. The solid particles in the molten salt will ...
