Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1-2. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
As shown in fig. 1 and 2, the present invention provides a fluidized bed hydrogenation reactor. The boiling bed hydrogenation reactor is an improvement on the basis of the prior art, and the arrangement of the boiling bed hydrogenation reactor in the prior art is adopted in the part with no structure described.
The ebullated bed hydrogenation reactor comprises: the reaction tank 1, the top of reaction tank 1 sets up gas outlet 2, the lateral wall of gas outlet 2 extends to the reaction tank inside and forms baffle 3. Therefore, the baffle is of a cylindrical structure as a whole, and the top of the baffle is connected with the gas outlet. The side wall of the gas outlet refers to the side wall formed around the gas outlet hole. Generally, the second feed port 4 is arranged at the upper part of the reaction tank, and the lowest point of the baffle plate is lower than the lowest point of the second feed port 4, which means that the baffle plate can block the entering particle materials of the second feed port from entering the gas outlet.
