Abstract

The invention provides a whirl cold hydrogen pipe of hydrogenation reactor, and aims to solve the problem that the uniformity of mixing of liquid and gas is low due to the small effective space of reactor in the prior art. The whirl cold hydrogen pipe comprises a feed pipe that is connected to the outlet of a cold hydrogen storage tank. The whirl cold hydrogen pipe also comprises a distribution ring pipe that is connected to the feed pipe and a plurality of nozzles that are arranged on the distribution ring pipe. The nozzles are evenly arranged on the annular external wall of the distribution ring pipe. Each nozzle is in a cylinder shape. The tail end of the lateral wall of each nozzle is provided with a notch, the tail end of each nozzle is provided with an end cover, and the directions of notches of the nozzles can be same or different. The provided whirl cold hydrogen pipe of hydrogenation reactor can be applied to petroleum refining.

Description

technical field [0001] The invention relates to the technical field of petroleum refining, in particular to a cyclone cooling pipe for a hydrogenation reactor. Background technique [0002] At present, for the petroleum refining and petrochemical industries, in the fixed-bed hydrogenation reactor in which the gas-liquid two-phase fluid flows side by side, the raw material oil and hydrogen are fully and uniformly mixed and reacted on the surface of the catalyst. , because the hydrogenation reaction process will generate a large amount of reaction heat, therefore, the reactor temperature will pass down the catalyst bed and gradually increase. However, too high reaction temperature will easily cause hot spots in the catalyst bed, accelerate the coking and sintering of the catalyst, shorten the service life of the catalyst, increase the frequency of vehicle shutdown for maintenance and catalyst replacement, and reduce the quality level and quality of the product. The economic e...
