Description

Fixing groove inserting device for hydrothermal reaction

Technical Field

The utility model belongs to the technical field of the chemical industry equipment technique and specifically relates to a fixed slot device is inserted in hydrothermal reaction is related to.

Background

The hydrothermal method is an effective method for inorganic synthesis and material treatment by heating and pressurizing a reaction system (or self-generated steam pressure) in a specially-made closed reactor by using an aqueous solution as the reaction system and creating a relatively high-temperature and high-pressure reaction environment to dissolve and recrystallize substances which are usually insoluble or insoluble. Hydrothermal method started from the experimental synthesis of minerals by k.f.e.schafhatt in 1845, and the development has been in the past for almost two hundred years.

According to different research objects and purposes, the hydrothermal method can be divided into the fields of hydrothermal crystal growth, hydrothermal powder preparation, hydrothermal film preparation, hydrothermal treatment, hydrothermal sintering, hydrometallurgy, inorganic films, various novel nano materials and the like. The method is respectively used for growing various single crystals, preparing superfine, non-agglomeration or less-agglomeration and well-crystallized ceramic powder, completing certain organic reactions or processing organic waste substances harmful to the living environment of human beings, completing sintering of certain ceramic materials at relatively low temperature and the like.

The hydrothermal method is widely applied to growing various single crystals, preparing functional ceramic powder, completing some organic reactions or treating some organic wastes which are harmful to the living environment of human beings, completing sintering of some ceramic materials at relatively low temperature and the like. However, since the hydrothermal process occurs in a closed container, the reaction pressure is high, and the high-tolerance reaction kettle material and the good sealing of the autoclave become prerequisites for the hydrothermal reaction. The hydrothermal reaction is affected by factors such as temperature, pressure, pH, precursor concentration, impurities and reaction time. Meanwhile, the harsh reaction conditions bring difficulty to the measurement of various parameters, people can only adjust the parameters by detecting reactants, and the hydrothermal reaction is regarded as a black box for a long time by the treatment, so that the industrial development of the hydrothermal method is influenced. The safety problem and the limitation of the reaction mechanism are key factors which hinder the application of the hydrothermal method, and the definition of the pressure and the real ion concentration in the reaction kettle is a necessary premise for solving the safety problem and further researching the hydrothermal reaction mechanism, so that the idea of improving the thermodynamic model of the relation between the pressure and the filling degree is provided.

A hydrothermal reactor, named as a miniature reactor, is low in cost and simple in structure compared with other reactors, adopts stainless steel as a pressure-bearing element, is internally lined with a polytetrafluoroethylene inner container and a PP L liner, is suitable for reaction of various strong acid, strong alkali and other media, is high in cleanness and free of any corrosion pollution, can be used for testing the reaction conditions of the media with the same components under different conditions or testing the reaction conditions of the media with different components under the same conditions.

The development of scientific research depends to a large extent on the equipment available. Crystal growth or material synthesis under hydrothermal conditions requires pressure reactors capable of holding highly corrosive solvents at high pressures, requires equipment that can be operated on a specification and is reliable under extreme temperature and pressure conditions. Due to the particularity of the reverse-seat conditions, the hydrothermal reaction has the following disadvantages compared with other reaction systems:

1) the growth process cannot be observed and is not intuitive;

2) the equipment requirement is high (high temperature and high pressure resistant steel, corrosion resistant lining), the technical difficulty is high (the temperature and pressure are strictly controlled), and the cost is high;

3) the safety performance is poor;

4) as the hydrothermal reaction is carried out at high temperature and high pressure, the solution fullness needs to be controlled, and the existing reaction kettle has the defects that the effective reaction volume of the device is too small, so that the yield is low and the reaction time is long.

Safety is a primary concern in experimentation and production. When heating, the volume of the fluid in the closed reaction kettle expands, and great pressure intensity can be generated. For example, in a fully filled reactor, the pressure generated can easily burst the autoclave even if the temperature is raised by only a few degrees. It is estimated that the capacity of the reactor is approximately 20000J for a volume of 100cm3 and a pressure of 20000psi (1378 bar). Also known as "bombs" because of the potential explosion hazard. Hydrothermal solutions at high temperatures (either acidic or basic) are extremely dangerous to humans if the reaction kettle explodes. The autoclave which breaks at high pressure corresponds to a digestion bomb, from which the danger of hydrothermal reactions is visible.

At present, the electrode plates are placed in a reaction kettle, a fixed support is not provided, the reaction effect is poor, the electrode plates are adhered together, and the electrode plates are difficult to recover in the later period.
