Problems solved by technology

If uneven raw materials are sent into the production device, it is easy to cause large fluctuations in pressure and temperature, and the production operation is unstable, causing safety hazards and prone to unqualified product quality
In order to solve the problem of uneven raw material oil, at present, it is usually to add a blending line outside the storage tank and use a pump for blending; or install an agitator on the tank wall for stirring and blending. These methods increase energy consumption and take a long time for blending , and the harmony is uneven

Abstract

The invention discloses a petrochemical raw material oil storage tank automatic blending device. The petrochemical raw material oil storage tank automatic blending device comprises an oil dischargingmain pipeline, an oil discharging branch pipeline, an oil discharging pump, a first valve, a second valve, an in-tank lower-part blending mechanism and an in-tank upper-part blending mechanism; the in-tank lower part blending mechanism comprises an oil collecting tank, a blending longitudinal pipe, a blending transverse pipe and spherical nozzles, at least one ring of the blending transverse pipeis arranged on the pipe body of the blending longitudinal pipe, and the blending transverse pipe is provided with multiple spherical nozzles; and the in-tank upper part blending mechanism comprises across-shaped pipe and spiral nozzles, and the cross-shaped pipe is provided with multiple spiral nozzles downwards longitudinally. According to the petrochemical raw material oil storage tank automatic blending device, extra energy consumption is not needed, the oil discharging pump is used as power when oil discharging, automatic blending of raw material oil is achieved in a storage tank, and good economic benefit is achieved; blending is conducted along with discharging, blending time is short, and the work efficiency is high; the blending mechanisms are reasonably distributed, uniformity ofblending is high, and the quality of products is advantageously improved; and assembling is simple, convenient and fast, and maintaining is easy.

Description

technical field [0001] The invention relates to the field of petrochemical equipment, in particular to an automatic blending device for petrochemical raw oil storage tanks. Background technique [0002] When the raw oil is unloaded into the storage tank, it is generally unloaded in batches; the properties and water content of the raw materials are inconsistent or even quite different between batches. If uneven raw materials are sent into the production device, it is easy to cause large fluctuations in pressure and temperature, unstable production operation, resulting in potential safety hazards and unqualified product quality. In order to solve the problem of uneven raw material oil, at present, it is usually to add a blending line outside the storage tank and use a pump for blending; or install an agitator on the tank wall for stirring and blending. These methods increase energy consumption and take a long time for blending , and the harmony is uneven. Contents of the in...
