Description
Technical field
The utility model relates to a kind of continuous hydro-thermal device, is mainly used in the synthetic of slightly solubility material.
Background technology
Hydro-thermal method originates from geology research nature and becomes ore deposit research, turns to the research of functional material afterwards.Reactive material obtains target product by various chemistry, physical action.Mainly contain hydrothermal oxidization, hydrothermal reduction, hydrothermal deposition, hydro-thermal hydrolysis, hydrothermal crystallization etc.What wherein hydrothermal crystallization was used is maximum.
The synthetic capital equipment of hydro-thermal method is an autoclave, adopts andnon-continuous operation manner, relies on motor to stir and realizes that material evenly mixes in the still.The intermittently operated production capacity is little, the cycle is long.Seal request to rotary part in the high-temperature high-voltage reaction process is very high, and the still internal pressure is big more, and is just high more to the requirement of sealing.At present the sealing means to the high pressure rotary part mainly contains mechanical seal and magnetic seal, in process of production, these two kinds of sealing means need frequent replacing seal to reach sealing effectiveness, and the time of not only having wasted has also increased the production cost of enterprise.
The utility model content
The purpose of this utility model is to provide a kind of continuous hydro-thermal device, can effectively solve in the present reactor to stir by motor to make under HTHP rotary part seal request height is needed the frequent problem of changing seal.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of continuous hydro-thermal device, comprise the batching still, device for transporting objects, hydrothermal reaction kettle group, the depressurized system that link to each other successively, described hydrothermal reaction kettle group comprises the reactor of several series connection, pipeline between described adjacent two reactors is provided with measuring pump, is equipped with a circulating pump that helps material to stir between the discharging opening of described each reactor outside and the charging aperture.
Preferably, described device for transporting objects comprises control valve and booster pump, and described control valve and booster pump are arranged on the pipeline of preparing burden between still and first reactor charging aperture; To the material pressurization of input reactor, so that reach better mixing.
Preferably, described depressurized system comprises one-level drawdown pump, surge tank, the second depressurized pump that connects successively, and described one-level drawdown pump links to each other with the discharging opening of last reactor; Keep the balance of turnover system material, the material that goes out system is reduced pressure to reach atmospheric pressure state.
Compared with prior art, the utility model has the advantages that: need not to use motor to stir, reduced the requirement to sealing ring, therefore the fault rate and the proportion of goods damageds of whole device reduce greatly, have also reduced the production input cost simultaneously, make production efficiency obviously promote.
