Heat transfer tube deposition visualization experiment device and method

The invention discloses a heat transfer tube deposition visualization experiment device and method, and the device comprises a main loop system composed of a main water tank, a main loop pump, a preheater, a mass flow meter, a test section and a condenser, and an impurity adding system composed of an impurity source box, a sludge pump, a preheater and a mass flow meter. The chemical control system is composed of a water supplementing tank, a chemical reagent tank and a peristaltic pump, the blowdown system is composed of a blowdown water tank and related pipelines, and the data acquisition module is composed of a temperature sensor and a pressure sensor which are connected with a computer. The invention further provides an experimental method of the device. The device can meet the research on the magnetite deposition rule inside and outside the heat transfer tube under the normal pressure condition, and can observe the interaction between fluid and particles in the process from supercooling to saturated boili
