Hydrogenation gas-liquid mixed filtering device

Abstract

The invention discloses a hydrogenation gas-liquid mixed filtering device, which comprises a cylinder body, a gas-phase inlet, a liquid-phase inlet, an agent discharging opening, a material outlet, aliquid-phase distributor, a filter set, a wire mesh and a filter tray. The filter set is composed of a plurality of filter single bodies. Each filter single body is of a tubular structure penetratingin the up-down direction, the wire mesh is arranged at the bottom of the filter set, the filter single bodies are arranged on the filter tray, filter center channels are formed by gaps between all thefilter single bodies, and baffles are arranged at openings in the upper parts of the filter center channels. An inlet of the liquid-phase distributor is connected with the liquid-phase inlet, and anoutlet of the liquid-phase distributor is arranged over the filter single bodies to enable liquid flowing out from the outlet of the liquid-phase distributor to enter the filter single bodies. The hydrogenation gas-liquid mixed filtering device is good in mixed filtering effect and high in anti-blocking property, scale is prevented from entering a hydrogenation reactor, thus the operation cycle ofa hydrogenation device is prolonged, the activity of a hydrogenation catalyst is improved, and the service life of the hydrogenation catalyst is prolonged.

Description

technical field [0001] The invention belongs to the technical field of chemical production equipment, in particular to a hydrogenation gas-liquid mixing filter device. Background technique [0002] In the field of petrochemical and coal chemical industry, in the process of hydrogenation production of oil products, due to the increasingly serious deterioration of raw material oil, high content of coking impurities such as diolefins, and rust caused by corrosion of equipment and process pipelines, etc. enter the hydrogenation reaction Scales will be produced after the reactor, covering the surface of the catalyst, deactivating the catalyst, and gradually increasing the pressure drop of the reactor, which will affect the normal production of the device in severe cases. Therefore, how to reduce the scale entering the hydrogenation reactor, reduce the coverage of the catalyst surface, and at the same time ensure that the oil and hydrogen are fully mixed, improve the activity and ...
