Energy-saving wax oil hydrogenation device in petrochemical industry

Abstract

The invention discloses an energy-saving wax oil hydrogenation device in petrochemical engineering, and relates to the technical field of wax oil hydrogenation, the energy-saving wax oil hydrogenation device comprises a wax oil hydrogenation device, circulation collectors, a pressurizing device, a feed inlet, a hydrogen tank and a plastic protective layer, the circulation collectors are fixedly connected to the outer surfaces of the two sides of the wax oil hydrogenation device, and the circulation collectors are fixedly connected to the outer surfaces of the two sides of the wax oil hydrogenation device; a pressurizing device is fixedly connected to the top of the wax oil hydrogenation device, and a feeding hole is fixedly connected to the top of the wax oil hydrogenation device. The round rubber blocks are used for buffering and dispersing the impact strength by falling off external impact, the strip-shaped clamping strips are connected through cooperation of the connecting plates, the impact force can be dispersed towards one end during impact by means of staggered connection between the connecting plates, the characteristic of dispersing the external impact is achieved, the service life of the device is prolonged, and the service life of the device is prolonged. The problem that the surface of the tank body is broken due to the fact that the tank body is not evenly pressed due to deformation of the tank body caused by external impact is solved, and the effect of protecting the outer surface of the tank body is achieved.

Description

technical field [0001] The invention relates to the technical field of wax oil hydrogenation, in particular to an energy-saving wax oil hydrogenation device in petrochemical industry. Background technique [0002] Wax oil hydrogenation unit is an industrial device of various types. According to the role of the reactor, it is divided into one-stage method and two-stage method. The two-stage method includes two-stage reactors. The first stage is used as a hydrofining stage to remove Nitrogen, sulfide, the second stage is the hydrocracking reaction section, the process flow of the one-stage fixed bed hydrocracking unit is that raw oil, circulating oil and hydrogen are mixed and then heated and introduced into the reactor. There are following problems at prior art: [0003] 1. Hydrogen is a very light gas. Due to its characteristics, it always floats upwards. Any gap will cause hydrogen leakage. Moreover, hydrogen is a very flammable gas. When it encounters impact and leakage ...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides an energy-saving wax oil hydrogenation device in petrochemical industry. One of the purposes is to have the characteristics of protecting and storing hydrogen, and to solve the problem that the hydrogen is very light, so that it always floats upwards, and the gap will cause The leakage of hydrogen gas, and hydrogen gas is a very flammable gas, if it encounters high temperature or open flame after leakage, it will cause an explosion problem; another purpose is to solve the problem that hydrogen gas will not be completely fused with wax oil. The fused hydrogen will accumulate inside, which will cause the problem of hydrogen leakage when filling, so as to achieve the effect of recycling and reusing the unfused hydrogen inside
