Abstract

The invention discloses a brand-new middle and low pressure steam spraying liquefier. The purposes that: (1), the liquefier is not blocked, the liquefaction is thorough, and the liquefaction effect is improved, (2), the liquefier is suitable for middle and low pressure steam, and the applied range is improved, and (3), the vibration and the noise are eliminated, are mainly achieved. A dividing device, an impacting device, two steam inlets and two spraying openings are created for the first time; a mixing structure that an inner circular ring and an outer circular ring of slurry are synchronously in contact with steam is uniquely created; the dispersion degree of a feed liquid is improved; the contact surface of the structure with the steam is increased; the microturbulence is enhanced; and the liquefaction effect is further improved. The structure is unique, and the technique and the performance lead over world standards.

Description

The low pressure steam Jet liquefier

Technical field

Patent of the present invention is that a kind of low pressure steam that adopts heats the equipment of liquefaction to slip, is mainly used in the liquefaction of starch milk liquefaction and various feed liquids.

Background technology

External steam Jet liquefier is not suitable for domestic low middle pressure situation, is prone to simultaneously stop up, thereby can not uses.Domestic equipment one is only to be fit to low-pressure steam, and is inapplicable to the mesohigh steam greater than 0.7MPa; The 2nd, the utilization not yet in effect of steam kinetic energy, the liquefaction effect is not ideal enough, causes waste; The 3rd, resistance is big, and power consumption is high.The 4th, need constantly to regulate, just can meet the demands the big and trouble of operation easier.

Summary of the invention

(1) have two steam air intakes (4 and 7) and two steam to spray import, this is world's initiative.Steam advances through spraying formation negative pressure drive feed liquid, promptly aspirates feed liquid, has utilized steam kinetic energy again.Feed liquid is sprayed also can form negative pressure suction steam.Form steam and feed liquid and drive mutually, this also is original creation.

(2) slip flows with circular, and inside and outside annulus contacts with steam simultaneously, has increased the contact area of slip and steam, and this also is original creation, and it helps strengthening microturbulence.

(3) utilization latest modern technological scientific and technological achievement, the segmenting device of setting and crash device are world's initiatives.They mutually combine and reach the dispersion slip, increase the steam contact, strengthen microturbulence, and then have improved the liquefaction effect.

The circular feed liquid structure of (4) two steam injection equipments and formation is fit to that low pressure steam is used and steam kinetic energy effectively utilizes.

The specific embodiment

(1) annulus that forms each other through steam steam inlet pipe 4 and jet blower 5 of slip is with circular outflow.

(2) steam penetrate through steam steam inlet pipe 4 and with slip in annulus contact.

(3) steam that flows into through another steam air intake 7 penetrates and contacts with the slip outer toroid through the gap that inner cone 9 and jet blower 5 form each other.All the other steam are then added by spray-hole 14.

When (4) flowing forward,, strengthened microturbulence on the one hand, promoted that simultaneously collision disperses each other, and then improved the liquefaction effect through segmenting device 10 and crash device 13 with the steam of slip inside and outside circle loop contacts and slip.

(5) steam admission 4 has reasonable clearance not stop up with assurance with jet blower 5 each other.
