Technical field
The present invention relates to a kind of chemical reaction equipment, be particularly suitable for but be not limited only to industrial chemical reaction kettle.
Background technology
Take the electrolyte that mainly can be used as lithium ion battery and be example as the lithium sulfide of the novel high polymer functional material raw materials such as polyarylene sulfide, because this compound is that a kind of chemical property vivaciously and is very easily decomposed and the material of oxidation, therefore in its manufacture process, reaction condition and reaction environment are had to stricter requirement.In the main method of present stage industrial production high-purity lithium sulfide, no matter directly by lithium metal, with sulphur simple substance, to be reacted or by its further improved liquid ammonia process for caustic soda purification, or take lithium hydroxide and hydrogen sulfide as the raw material preparation, and all relating to the use of poisonous and hazardous gas raw material, the danger of operation is large.Active raw material and/or the product for chemical property; course of reaction at its manufacture; or after reaction to subsequent treatment such as the separation of material, filtrations, sometimes also need to as the protection of the inert gas environments such as nitrogen under carry out, to guarantee and the quality of raising reaction/product.Current conventional chemical reaction equipment, industrial traditional batch tank reactor etc. particularly, although its preparation process can be carried out in the environment relatively isolated in maintenance, but reacted intermediate material transfer process is all to be directly exposed in air, thereby very easily make material oxidized or introduce impurity, can affect undoubtedly purity and the yield of end product.
Summary of the invention
For above-mentioned situation, the invention provides a kind of chemical reaction equipment and can be satisfied with and address the above problem, and this chemical reaction equipment is particularly suitable for but is not limited only to the reaction unit of industrial chemical reaction autoclave.
The basic structure of the improved chemical reaction equipment of the present invention is in the reaction vessel with heating arrangement (as heating arrangements commonly used such as the electrical heating that adopts, jacket type Steam Heating):
---by filtration, the reaction vessel content space is divided into to top reaction compartment and below filter space, this filtration can adopt version commonly used as current as filter screen, filter plate etc., material can be selected according to the characteristics of concrete preparation feedback, as the special material etc. that adopts acidproof/alkali or have anti-other corrosive nature;
---be provided with stirring structure in reaction compartment, can adopt equally stirring structure or the device of current common type;
---in reaction compartment, the position of nearly filtration is provided with the material outlet;
---be provided with the liquid material peripheral passage that is connected through pump structure and the discharging opening of liquid material between filter space and reaction compartment;
---be provided with air inlet and gas outlet for reaction gas in the reaction vessel content space.
On the basis of above-mentioned basic structure, said liquid material discharging opening, can preferably adopt between the Matter Transfer path connector of pump structure in said liquid material peripheral passage and reaction compartment, through the fluid transformational structure, said liquid material discharging opening is set.Wherein, said this fluid transformational structure is preferably valve mechanism or parts.
Further, a kind of plain mode of said this conversion valve, can be adopted as the liquid material circulation control valve arranged between the Matter Transfer path connector of the pump structure in the liquid material peripheral passage and reaction compartment respectively, and the discharging control valve arranged in liquid material discharging pipeline.
In said structure, said air inlet and gas outlet for reaction gas is respectively at least one, can be according to the setting that needs of different or specific reaction.For example, said air inlet and gas outlet for reaction gas can be set at the reaction compartment position and/or one or two air inlet at filter space position usually, and a gas outlet that is arranged on the reaction vessel top.Wherein, said gas outlet preferably is arranged on the lid of reaction vessel.
In addition, at reaction compartment and/or the filter space position of said reaction vessel, also can further be provided with as required the observation panel for the observing response interior volume.
The above-mentioned various improvement that can further select or optimal way, can be adopted separately, also can or need to combine employing in the mode of any combination according to actual conditions.
Obviously, by foregoing, be appreciated that, the improved chemical reaction equipment of the present invention not only can be by promoting the Matter Transfer path by pump structure, coordinate conventional stirring structure further to strengthen the mixing realized reaction mass, and the particularity that is particularly suitable for and meets because of preparation feedback need have gaseous state material or gaseous environment participate in or discharge, and need maintain the requirement as specific reaction/processing environment conditions such as inert atmospheres when the post processings such as course of reaction and/or the rear reaction mass separation of reaction, the material filtering that reaction after making to be dropped into by raw material proceeds to after having reacted separates, the subsequent treatment such as discharge, can under required environment/condition, complete continuously fully, thereby be conducive to guarantee the quality of reaction/product and/or the safety of environment, and this reaction unit is simple in structure, easy to operate, more be particularly suitable for promoting and adopting in the Chemical Manufacture of different scales.
Below in conjunction with the specific embodiment by the accompanying drawing illustrated embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to following example.Without departing from the idea case in the present invention described above, various replacements or the change according to ordinary skill knowledge and customary means, made, all should comprise within the scope of the invention.
