Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to make more clear and definite definitions of the scope of the present invention.
Referring to the attached figure 1 of the specification, the high-temperature liquid phase catalytic reactor comprises a main body which is a reaction kettle 1, wherein the upper part of the reaction kettle is provided with a coking zone inlet 11, the top of the reaction kettle is provided with a catalyst feeding port 12, a coking zone outlet 13 and an exhaust port 14, a pipeline of the exhaust port is provided with a safety valve, and the safety valve ensures that the reaction kettle is in a certain pressure range. The catalyst is fully heated by the heat of the burning zone before falling to the upper liquid level of the material in the feeding bin. The bottom of the reaction kettle is provided with a material outlet 15, the reaction kettle is internally provided with a double-layer metal net sleeve 2, the double-layer metal net is a sleeve, the upper end and the bottom end of the double-layer metal net sleeve are fixed with the inside of the reaction kettle, and the double-layer metal net sleeve is beneficial to the uniform distribution of heat sources in the whole reaction kettle so as to ensure the uniform temperature distribution in the reaction kettle. The inside feed bin 3 that throws is equipped with of metal mesh cover, throws feed bin upper mouth opening, throws the feed bin bottom and is equipped with material entry 16.
