Description
Technical field
The utility model belongs to the chemical plant installations field, is specifically related to a kind of production of propylene oxide distributor.
Background technology
At present in producing propylene oxide by chlorohydrination method through about 100 ℃ of the saponification raffinates of saponification column, need to carry out flash distillation to it and reclaim heat through flash tank.Flash tank is a negative-pressure operation, and the saponification raffinate is in fluidized state when entering flash tank, and the saponification raffinate of fluidized state adds that the solid particle of raffinate inside causes seriously washing away nozzle easily like this.For above-mentioned reasons, nozzle can be caused the injector of flash drum overhead often to stop up after washing away, so the life cycle of the distributor of flash tank is all very short.Shut-down is overhauled with regard to needs when the vacuum of flash tank can't satisfy the production needs, and the general time between overhauls(TBO) is about 3 months.Frequent like this shut-down, overhaul, going into operation causes lot of manpower and material resources loss, the production cost of expoxy propane also rises thereupon.
In view of the foregoing, be badly in need of a kind of saponification raffinate of invention and be evenly distributed feed distributor simple in structure, easy for installation, that reliability is high.
Summary of the invention
For addressing the above problem, the utility model provides a kind of saponification raffinate to be evenly distributed, production of propylene oxide distributor simple in structure, easy for installation, that reliability is high.
The utility model is realized by following technical scheme:
This production of propylene oxide distributor, comprise distributor, distributor is positioned at tower body, comprise charging aperture, sleeve, upper plate, lower roof plate, this distributor also comprises the deflection plate in the annular region between sleeve and tower body, described deflection plate is fixedlyed connected with lower roof plate with upper plate, and the direction of deflection plate is charging aperture dorsad, and deflection plate at least respectively has one in the charging aperture both sides; Described charging aperture is fixedly connected with nozzle near an end of sleeve.
The longitudinal edge of above-mentioned deflection plate is fixedlyed connected with the medial surface of tower body, the angle of the tangential direction of deflection plate and tower body is not more than 90 degree, is preferably 45 degree, and the baffling effect to material under this angle is best, when material during, material is evenly distributed in the tower body by throat-fed.
In order to reduce material washing away to tower body, therefore at the medial surface applying stiffener of tower body, stiffener is the tubular structure of longitudinal opening, the last lower limb of stiffener is fixedlyed connected with lower roof plate with upper plate respectively, the lateral surface of stiffener and the medial surface of tower body fit, and the medial surface of stiffener is fixedlyed connected with the longitudinal edge of deflection plate.
The cross-sectional area of said nozzle is not more than the cross-sectional area of charging aperture, when entering charging aperture, material make the saponification raffinate when jetting nozzle, keep certain speed, allow raffinate and nozzle contact-making surface minimum, the boiling of raffinate is just in the inner space of distributor, so just greatly reduce saponification raffinate washing away to distributor, the raffinate that splashes on the tower wall is stopped by stiffener, other liquid phase was seethed with excitement before falling into flash tank bottom liquid level by the distributing disc of the distributor back that evenly distributes, to collect the heat in the raffinate to greatest extent.
1～4 through hole is arranged on the upper plate of distributor, through hole is preferably 2, usually the through hole on the distributor is 40-60, through hole is used for checking and the cleaning distributor, the through hole number causes the heat in the tower body to scatter and disappear more, therefore through hole is reduced the heat that can reduce in the tower body and scatter and disappear, the lid that matches is with it arranged on the through hole.
Production of propylene oxide of the present utility model is with the beneficial effect of distributor; adopted after the distributor of said structure, effectively controlled the locational space of the boiling of saponification raffinate, prevented saponification raffinate washing away distributor; protect tower body, prolonged the service life of distributor greatly.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further explanation.
This production of propylene oxide distributor, be positioned at tower body 6, comprise charging aperture 1, sleeve 8, upper plate 9, lower roof plate 10, this distributor also comprises the deflection plate 3 in the annular region between sleeve 8 and tower body 6, deflection plate 3 and upper plate 9 and lower roof plate 10 welding, and the direction of deflection plate 3 is charging aperture 1 dorsad, deflection plate 3 is symmetrical distribution in charging aperture 1 both sides, have 18, in actual production, can set the number of deflection plate 3 according to concrete needs; Distributor also comprises stiffener 7, stiffener 7 is the tubular structure of longitudinal opening, the last lower limb of stiffener 7 welds with upper plate 9 and lower roof plate 10 respectively, and the lateral surface of stiffener 7 and tower body 6 medial surfaces fit, and the medial surface of stiffener 7 is fixedlyed connected with the longitudinal edge of deflection plate 3.
Charging aperture 1 is fixedly connected with nozzle 2 near an end of sleeve 8; nozzle 2 is furnished with elbow and threeway; adopt after this nozzle and the above-mentioned deflection plate; effectively control the locational space of the boiling of saponification raffinate; prevented saponification raffinate washing away to distributor; protect tower body, prolonged the service life of distributor greatly.
