Underground solid-containing heavy dirty oil tank and solid-containing heavy dirty oil delivery method

Abstract

The invention discloses an underground solid-containing heavy dirty oil tank and a solid-containing heavy dirty oil delivery method. The underground solid-containing heavy dirty oil tank comprises an underground solid-containing heavy dirty oil tank main body, a device dirty oil discharging pipeline is connected to the side wall of the underground solid-containing heavy dirty oil tank main body, a discharging port pipeline is arranged in an inner cavity of the underground solid-containing heavy dirty oil tank main body, an outlet of the discharging port pipeline penetrates through the top wall surface of the underground solid-containing dirty oil tank main body and is connected with a solid-containing heavy dirty oil delivery pipeline, a plurality of inert gas vertical pipes are arranged around the discharging port pipeline, the inert gas vertical pipes and the discharging port pipeline are both of a straight pipe structure, the inert gas vertical pipes and the discharging port pipeline are both arranged in the height direction of the underground solid-containing dirty oil tank main body, outlets of the inert gas vertical pipes face an inlet of the discharging port pipeline, inlets of the inert gas vertical pipes penetrate through the top wall surface of the underground solid-containing dirty oil tank body and are connected with an inert gas conveying pipeline, and the outlets of the inert gas vertical pipes and the inlet of the discharging port pipeline do not make contact with the inner wall of the bottom of the underground solid-containing dirty oil tank main body. The method is low in cost and high in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of heavy oil production in petrochemical and coal chemical industries, in particular to an underground solid heavy dirty oil tank and a method for sending out solid heavy dirty oil. Background technique [0002] With the continuous development of heavy crude oil processing technology, as well as breakthroughs in direct coal liquefaction technology and pulverized coal pyrolysis technology. The proportion of heavy crude oil processing and heavy coal tar processing enterprises in domestic chemical enterprises is increasing year by year, and the storage and transportation of high-solid slurry state oil phase medium in production equipment is facing great technical difficulties. The design and structure of the underground heavy oil tank installed in the traditional heavy oil production equipment can no longer meet the storage and maintenance requirements of high viscosity and high solid heavy oil (such as pyrolys...
