The invention relates to a pulse type supercritical fluidization device for preventing segregation of multi-element particles, wherein the pulse type supercritical fluidization device consists of a fluid supply system, a cylindrical fluidized bed body, a fluid heating system, an electromagnetic valve and a pressure and temperature information acquisition and data processing system; the device mainly comprises a water supply tank, a flowmeter, a high-pressure plunger pump, a heat exchanger, a spiral pipe heater, a pulse electromagnetic valve, a fluidized bed, a pressure sensor, a thermocouple,a water tank and a data acquisition and output terminal (computer). The water supply tank is used for providing normal-temperature and normal-pressure water. The high-pressure plunger pump is used forincreasing the pressure value of the system. The fluid heating system is used for heating fluid. The computer is connected with the thermocouple and the pressure sensor, and is used for carrying outpost-processing on data information and transmitting an instruction to the pulse electromagnetic valve. The pulse electromagnetic valve is used for controlling a valve of the pulse electromagnetic valve according to a signal transmitted by the computer, so that fluid is input into the fluidized bed in a pulsating wave flowing form. According to the pulse type supercritical fluidization device forpreventing segregation of the multi-element particles, the related equipment is simple in structure, low in cost and easy to maintain, and the segregation phenomenon occurring in the multi-element particle fluidization mixing process can be effectively improved.
Description
[0001] The invention relates to a pulse type supercritical water fluidization device for preventing multiple particle segregation, and belongs to the technical field of physical experiment equipment. Background technique [0002] As a high-temperature and high-pressure fluidized medium, supercritical water has physical and chemical properties such as high diffusivity, high solubility, and good mass and heat transfer, and can directly treat wet biomass without drying. Fluidized bed has the advantages of good mixing of solid particles, high heat transfer efficiency, large fluid-solid contact area, etc., and has been more and more widely used in industrial processes. The introduction of supercritical water on the basis of the fluidized bed can combine the advantages of the two well to solve many problems that are difficult to solve in traditional tubular reactors. However, since the entire fluidized bed reactor is in a high temperature and high pressure environment, it is difficu...
