Problems solved by technology

[0002] In the production of naphtha, hydrodesulfurization treatment is required. In this process, due to the light quality of hydrogen, the part that has not completely reacted with naphtha will gather on the top side of the tank. In order to ensure hydrogenation The effect of desulfurization, so it is often necessary to replenish hydrogen many times, and the part on the top side of the tank is difficult to be used, resulting in waste of hydrogen, and the rise of hydrogen will form floating bubbles on the liquid surface, and hydrogen is trapped in the bubbles It will also cause incomplete hydrogen reaction, so we designed a pre-hydrogenation feed device for naphtha production

Abstract

A pre-hydrogenation feeding device for naphtha production, the invention belongs to the field of feeding devices, comprising a tank body, an exhaust disc, an inflator, a vacuum pump, a discharge port, a feed port, the inner wall of the tank The bottom surface of the tank is fixedly equipped with an exhaust disc, the exhaust disc is provided with an inner cavity, the other end of the spring is fixedly connected with the top surface of the exhaust disc, the top surface of the inner wall of the tank is provided with an annular groove, and the upper side of the inner wall of the annular groove The left and right sides are respectively provided with installation grooves, and multi-stage electric telescopic rods are respectively fixedly installed in the installation grooves. Bearings are arranged in the annular grooves. A groove is opened in the middle. The invention has an ingenious structure and is convenient to use, and can conveniently recycle the hydrogen on the top side of the tank body, and can crush the bubbles generated on the liquid surface during the hydrogen recovery process, so as to improve the utilization rate of the hydrogen.

Description

technical field [0001] The invention belongs to the field of feeding devices, in particular to a pre-hydrogenation feeding device for naphtha production. Background technique [0002] In the production of naphtha, hydrodesulfurization treatment is required. In this process, due to the light quality of hydrogen, the part that has not completely reacted with naphtha will gather on the top side of the tank. In order to ensure hydrogenation The effect of desulfurization, so it is often necessary to replenish hydrogen many times, and the part on the top side of the tank is difficult to be used, resulting in waste of hydrogen, and the rise of hydrogen will form floating bubbles on the liquid surface, and hydrogen is trapped in the bubbles It will also cause incomplete reaction of hydrogen, so we have designed a pre-hydrogenation feed device for naphtha production. Contents of the invention [0003] The invention provides a pre-hydrogenation feed device for naphtha production to...
