Discharging control device for particle materials in chemical reaction tower

Abstract

The invention provides a discharging control device for particle materials in a chemical reaction tower, which comprises a discharging inclined pipe, a discharging vertical pipe and a plugging device, wherein the discharging inclined pipe is provided with a hinge seat at an opening of the discharging inclined pipe; the discharging vertical pipe is vertically and downwards arranged on the discharging inclined pipe and is communicated with the discharging inclined pipe; the plugging device comprises a flange cover, a supporting flange and a blocking piece, the supporting flange is arranged at the opening of the discharging inclined pipe, the flange cover is arranged on the outer side surface of the supporting flange, the flange cover and the supporting flange are both hinged to the hinge seat, the blocking piece is inserted into the discharging inclined pipe, a connecting rod assembly is connected between the blocking piece and the supporting flange, the connecting rod assembly is used for driving the blocking piece to slide in the discharging inclined pipe relative to the supporting flange, a traction assembly is connected between the flange cover and the blocking piece, and the traction assembly is used for driving the blocking piece to move in the discharging inclined pipe so as to conduct discharging control over the discharging vertical pipe. The discharging speed of the chemical particle materials can be controlled, meanwhile, the discharging process is in a closed environment, and pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical production equipment, in particular to a control device for discharging granular materials in chemical reaction towers. Background technique [0002] The petrochemical industry widely uses granular catalysts in the fields of aromatics purification and aviation kerosene refining to remove residual olefins, colloids, asphalt, basic nitrogen compounds and other impurities in oil products. However, the service life of the granular catalyst is short, and the general reaction tower needs to be discharged and replaced after 4 months to half a year. Usually, a simple flange cover is installed at the discharge manhole of the granular catalyst. When discharge is required, the flange cover is manually disassembled to control the discharge. It is also impossible to control the feeding speed during unloading. During the unloading process, a large amount of waste particles leak and cannot be collected effecti...
