Experimental system suitable for supercritical water oxidation intermittent operation

The invention belongs to the technical field of environmental protection and solid waste treatment, and discloses an experimental system suitable for supercritical water oxidation intermittent operation. A gaseous oxidizing agent gas cylinder and an inert gas cylinder are both connected to an inlet of a gas flowmeter, and the front end of the inlet of the gas flowmeter is connected to a first pressure meter; an outlet of the gas flowmeter is successively connected to a non-return valve, a first stop valve and a gas inlet of a reaction system; a pipeline between the non-return valve and the first stop valve is connected to a branch, and a second stop valve is installed on the branch; The reaction system is provided with a cooling water inlet and a cooling water outlet; the cooling water inlet is connected to the bottom of a cooling water tank through a water pump; the cooling water outlet is connected to a cooling water cooler; and the cooling water cooler is arranged above the coolingwater tank and is used fo
