Unbounded ejector for conveying condensed oil and its conveying method

Abstract

The present invention relates to the unbounded ejector for conveying condensed oil and its conveying method. The unbounded ejector includes one assembly comprising a nozzle seat, a heat insulating seat and a sleeve with steam inlet and steam outlet; one mixing section with two ends connected to sealing washer, flange and end cap with a union; one passage beside the flange central hole and with one end communicated with a heating layer, a steam inlet at one end and a steam outlet at the other end; nozzle installed in the inclined hole in the nozzle seat, ring partition board, washer, and positioning board. The ejector has no driving unit. The present invention adopts direct heating of medium for saving steam and fast heating of condensed oil and unbounded ejection with coagulation of condensed oil in the equipment.

Description

technical field

[0001] The invention relates to a heating device and technology using steam ejection, in particular to a method and an unbounded ejector which can be used in petroleum, chemical industry, transportation and other processes involving direct heating of a medium with high viscosity. Background technique

[0002] At present, the ejection device commonly used in the industry is designed according to the principle of bounded ejection. The ejected medium flows out from the nozzle at high speed, and the ejected medium is sucked into the mixing chamber from around the nozzle due to the suction force and mixed with the ejected medium. , by controlling the shape of the mixing chamber, a uniform jet flow can be obtained at the outlet of the ejector device. Since the bounded injection device has the advantage of fully mixing the two media in a cavity of a certain shape, there are many invention patents designed according to the principle of boun...
