Embodiment Construction

[0012] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0013] refer to figure 1 , one A dry-type hydrothermal method, the dry-type hydrothermal reaction kettle includes a pressure gauge, a thermometer, a non-reactive gas port, a flange, a reaction kettle cover, an inner kettle body and an outer kettle body.

[0014] After the hydrothermal material is crushed and dispersed, it is sent into the dry-type hydrothermal reaction kettle, and the reaction kettle cover, inner kettle body and outer kettle body are tightened and sealed with flanges. After the pressure gauge and thermometer are installed, the non-reactive gas is passed through The mouth is used to inflate and pressurize the reactor, and when the pressure in the reactor is higher than the saturated vapor pressure of water at the set reaction temperature, the air intake is stopped. Finally, the temperatur...

Abstract

The invention relates to a dry type hydrothermal device and method, and belongs to the field of water heating. The dry type hydrothermal device comprises a pressure gauge, a thermometer, an inert gas port, a flange, a reaction kettle cover, an inner kettle body and an outer kettle body. Compared with the traditional water heating method, the reaction kettle is pressurized by using inert gas instead of water vapor pressurization of the traditional hydrothermal method, and the hydrothermal reaction is carried out at a set temperature by directly using the moisture of the material, so that the pretreatment process of the hydrothermal reaction material is omitted, a large amount of water resources are saved, and the cost is reduced; meanwhile, the water content of the hydrothermal product is low, the treatment cost of subsequent drying or secondary utilization is reduced, and the cost is further reduced.

Description

technical field [0001] The invention belongs to the field of hydrothermal technology, in particular to a dry hydrothermal device and method. Background technique [0002] Hydrothermal is a chemical unit process, which is the process of decomposing substances to form new substances by using water to increase the temperature under high pressure. The current hydrothermal process is to mix the material with a high proportion of water, and use water vapor to increase the pressure in the container. No small trouble. Therefore, seeking a new efficient and economical hydrothermal method has become a problem to be solved in the industry. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a dry hydrothermal method. Compared with the traditional hydrothermal method, the present invention uses an inert gas to pressurize the reactor to replace the steam pressurization of the traditional hydrothermal, dire...
