Abstract

The invention provides a low-energy-consumption high-precision feeding control system, which belongs to the technical field of supercritical water treatment and comprises a feeding subsystem and a flushing subsystem. The feeding subsystem comprises a feeding pipe connected with the hazardous waste buffer tank and the reactor, and a hazardous waste conveying pump, a flow detection device and a hazardous waste high-pressure pump which are sequentially arranged on the feeding pipe; the flow detection device comprises an electromagnetic flowmeter and a differential pressure type flowmeter which are connected in series; the flushing subsystem comprises a flushing water tank arranged on one side of the hazardous waste buffer tank, a forward flushing branch system and a reverse flushing branch system, wherein the forward flushing branch system and the reverse flushing branch system are connected with the flushing water tank. According to the low-energy-consumption high-precision feeding control system provided by the invention, the conveying precision is improved; the problem that the error of the detection result is large when only an electromagnetic flowmeter is used for measurement in an existing feeding control system is solved, and the measurement precision is improved; the flow detection device and a conveying pipeline connected between the hazardous waste conveying pump and the hazardous waste high-pressure pump are prevented from being blocked, and the measurement precision is improved.

Description

technical field [0001] The invention belongs to the technical field of supercritical water treatment, and more specifically relates to a low-energy-consumption and high-precision feed control system. Background technique [0002] Supercritical Water (SCW for short) refers to water in a special state whose temperature and pressure are both higher than its critical point (T=374.15°C, P=22.12MPa). Supercritical Water Oxidation (SCWO) technology is a technology that can realize deep oxidation treatment of various hazardous wastes. It uses the unique physical and chemical properties of supercritical water to completely dissolve oxidants and organic substances in supercritical water. With supercritical water as the reaction medium, through a homogeneous oxidation reaction, the organic matter is quickly and thoroughly converted into clean CO2, H2O, N2 and other harmless small molecules, and the conversion of S and P into the highest-valent salts is stabilized , the heavy metal oxi...
