Description
Technical field
The utility model belongs to chemical machinery field, is related to a kind of reflux ratio controller, is mainly used in chemical industry rectifying column
Backflow and produced quantity control.
Background technology
Rectifying column is that chemical industry one of is mainly equipped, and almost all of chemical products --- especially petrochemical industry is (organic
Chemical industry) product is all finally to obtain finished product by rectifying.The operation of rectifying column, when control kettle heating amount, second, control backflow
With the ratio (i.e. reflux ratio) of extraction, that be most difficult to is the latter.Existing reflux ratio controller is waved by what University Of Tianjin developed
Formula reflux ratio controller, critical piece are outer barrel, dividing plate, liquid separation bucket and magnetic valve, by waving to adjust reflux ratio for liquid separation bucket,
The flow of backflow and extraction is pulse, i.e., one one, and flow can not be measured.When reflux ratio is very big and during very little,
Such as reflux ratio 1/10, return time 6 seconds, 54 seconds time is produced, interval time is very long, causes rectifying column operation unstable.This time
Flow ratio controllers only have application in laboratory at present, and the factory industrially bought is just given it up with after a period of time
, reason one is instability of flow, second, liquid separation bucket stainless steel zipper usage time it is short-some months just rubs.Because not into
Ripe reliable reflux ratio controller, the reflux ratio of the present middle-size and small-size rectifying column in chemical plant is all artificial manual control, by extraction valve and
Backflow, extraction flowmeter control reflux ratio.Large Scale and Continuous rectifying column can use automatic regulating valve control capacity of returns, but this centering
Small-sized tower and batch column are not suitable with, when it is also immature to the automatic control technology of low discharge, second, the flow of batch column is in itself
With regard to unstable, automatic control also simply has been moved to valve on computer-essence or manual adjustment.
In order to solve the problems, such as reflux ratio controller, University Of Tianjin proposes a series of patents, such as still huge utility model
Night curtain type of reflux ratio controller (CN 1236656A), the having of the utility model such as Song Guangfu, which separates, covers that dividing plate is auxiliary transmission
The overflow-type reflux ratio controller (CN 1043960C) of mechanism, the having of the utility model such as Wang Hansheng separate that roller is auxiliary transmission
The overflow-type reflux ratio controller of mechanism and cover the dividing plate auxiliary overflow-type reflux ratio controller (CN for having transmission mechanism with separating
1093298A), having for the utility model such as Wang Hansheng separates the auxiliary aperture outflow formula reflux ratio control for having transmission mechanism of covering dividing plate
Device processed and with separate cover the auxiliary transverse slot reflex ratio controller (CN 2207865Y) for having transmission mechanism of dividing plate,
But these devices are all more complicated, are not promoted industrially.
Utility model content
The purpose of the utility model is to propose a kind of rotating disc type reflux ratio controller, simple in construction, and control is accurate, not only may be used
For middle-size and small-size rectifying column, can be used for large-scale rectifying column, a mounted disc reflux ratio controller with regard to can substitute reflux pump,
Automatic regulating valve and return tank.
The technical solution of the utility model is rotating disc type reflux ratio controller, including outer barrel, liquid distributing trough, dividing plate, tune

The methods of be fixed together with bearing；Liquid distributing trough is cylinder open above, and it is small that cylinder side half is covered with φ 0.5~15
Hole, half is non-porous, two middles by cylinder outside two vertical laths separate, bottom centre-drilling hole, rotating shaft (is used through hole and bottom
The methods of welding) it is fixed together；Liquid distributor bottom cover member insertion bearing is exposed in rotating shaft lower end, and liquid is exposed in rotating shaft upper end
Linked together on distributor along part with adjusting rod with the methods of grafting or pin；Adjusting rod passes through sealing device (filler or machine
Tool etc.) outer barrel is stretched out, it is connected with controlled motor, the angle of liquid distributing trough rotation is rotated with controlled motor drive shaft；Cylinder
A liquid outlet is respectively opened in bottom dividing plate both sides, one be refluxing opening, one be extraction mouth.
Further, outer barrel upper cover side sets liquid-inlet, connects rectifying column one fluid issuing of condenser.
Further, the angle of liquid distributing trough rotation is controlled with computer (DCS) or meter specially, to reach regulation backflow
The purpose of ratio.
Further, controlled motor drive shaft, manual adjustment reflux ratio are substituted with handwheel or adjusting quantity meter.
Beneficial effect：A kind of new reflux ratio controller is proposed, the backflow and produced quantity control, automatic control to rectifying column are adjusted
Section, stability of flow, the problem of overcoming existing counter flow controller flow pulsation.This reflux ratio controller is referred to as rotating disc type backflow
Than controller, by drum (can be circle basin, band truncated cone-shaped etc.) shape liquid distributing trough demifacet perforate, by rotation distributing trough
Angle control backflow distribution ratio.This reflux ratio controller is simple in construction, easy to manufacture, and control is accurate.This reflux ratio control
Device processed can be not only used for middle-size and small-size rectifying column, can be used for large-scale rectifying column, with a mounted disc reflux ratio controller just
Three reflux pump, automatic regulating valve and return tank equipment are instead of, are reduced investment outlay, it is simple to operate.
