Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] A kind of supercritical water reaction device with desalination function of the present invention, such as figure 1 As shown, including reactor 1, the working pressure in reactor 1 is 25MPa-30MPa, the working temperature is 400°C-650°C, and the reactor can be heated by other auxiliary heaters. The upper end of the reactor 1 is provided with a sewage inlet and an oxygen interface. The sewage inlet is connected to the sewage inlet pipe 3, and the sewage is passed into the reactor 1 through the sewage inlet pipe 3. The oxygen interface is connected to the oxygen pipe 4, and the oxygen reacts through the oxygen pipe 4. Oxygen is delivered in device 1. Between the inner side walls of the reactor 1, a precision filter 9 and a plurality of partitions 7 are sequentially arranged from bottom to top. The filtration precision of the precision fi...

The invention discloses a supercritical water reaction device having desalting function, which includes a reactor. A wastewater inlet and an oxygen port are disposed on the top end of the reactor. A pressure meter interface and a thermocouple interface are arranged on the outer side wall of the reactor. A pressure meter is arranged in the pressure meter interface and a thermocouple is arranged inthe thermocouple interface. A precise filter screen and a plurality of separation boards are successively disposed between the inner side walls of the reactor from bottom to top, wherein an adsorptionlayer is arranged on the upper surface of each separation board. A plurality of wastewater channels are formed between a part of edges of each separation board and the inner side walls of the reactor. Two adjacent wastewater channels are in staggered distribution in the vertical direction. A wastewater through hole at the top end is far away from the wastewater inlet. A wastewater outlet and a salt discharge port are arranged on the lower end of the reactor. When being used for treating wastewater, the supercritical water reaction device can greatly reduce the settlement quantity of salts inthe reactor, thereby preventing the reactor from being blocked.
Description
technical field [0001] The invention belongs to the technical field of waste water treatment equipment, and in particular relates to a supercritical water reaction device with a desalination function. 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 has the properties of both liquid and gaseous water. In this state, only a small amount of hydrogen bonds exist. The dielectric constant is similar to that of polar organic solvents. It has a high diffusion coefficient and low viscosity. In the supercritical state, organic matter and oxygen can dissolve with supercritical water, so that the heterogeneous reaction becomes a homogeneous reaction, which greatly reduces the resistance of mass transfer and heat transfer. [0003] Based on the unique physical and chemical properties of supercritical water, supercritica...
