Background technology
When controlling outside tower, prior art control refluxes and is to use the flow indicating meter of direct type or indirect-type, regulates fluid flow that flows back in the tower and the purpose that recently reaches control that flows out the outer fluid flow of tower.Prior art has following drawback in regular job: be unable to do without operator's control 1), all the time; 2), the flowmeter useful life of display type is not all long, particularly when being used for mordant medium; 3), when the medium that is measured has high-solidification point, flowmeter needs the environment that is higher than freezing point temperature, therefore the difficulty of implementing is very big, and temperature is when too high, flowmeter is fragile; 4), be under high vacuum or the high pressure conditions when system, flowmeter commonly used easily causes leakage phenomenon because of the sealing problem of self.
When the tower inner control, the general method that adopts at the built-in cooling device of cat head is controlled capacity of returns with the method for regulating coolant flow, still can't measure and is difficult to accurately control reflux ratio owing to capacity of returns.
The utility model content
The purpose of this utility model is in order to solve and overcome the shortcoming of existing reflux ratio control device, and a kind of operator's of need not control, reliability height, refluence control device of rectifying column that cost of manufacture is low are provided.
The utility model solves the technical scheme that its technical problem adopts: this refluence control device of rectifying column, mainly comprise slit gauge line, collecting tank, collecting tank, discharge nozzle, collecting tank ring flat-plate and collecting tank base plate, and be subjected to liquid space by what collecting tank base plate, collecting tank ring flat-plate and tower body inwall constituted; Be provided with the collecting tank base plate in tower body inside, the outward flange of collecting tank base plate is connected with the tower body inner wall sealing, the inward flange of collecting tank base plate and collecting tank ring flat-plate are tightly connected, and collecting tank is embedded among certain diameter opposite ends of collecting tank ring flat-plate and with collecting tank ring flat-plate and collecting tank base plate and is tightly connected; One group of wide slit gauge line of different seams passes sump bottom and is tightly connected with collecting tank, the vertical lower of slit gauge line is provided with the collecting tank that the top is not sealed, its number of packages is consistent with the slit gauge line, all be connected with discharge nozzle every collecting tank bottom, discharge nozzle is connected with the valve of controllable switch outside tower body.
Slit gauge line described in the utility model is 2-5 a group, generally speaking can be more than 5, and can be equidistantly or unequal-interval be arranged on the same straight line.
Described slit gauge line described in the utility model does not seal pipe fitting for the middle two ends that have slit.
The lower surface of the upper surface of described collecting tank described in the utility model and slit gauge line maintains certain spacing, generally between 1mm-200mm.
The effect that the utility model is useful is: 1. generally speaking can be more than 5 owing to the wide slot flow meter of a plurality of different seams is installed in reflux ratio controller, under special structure, as long as opening or closing of control corresponding discharge meter fairlead valve, just can be combined into a series of different backflow ratios, therefore reflux ratio that can be required according to technology, find corresponding switch combination, disposable adjusting can guarantee process system stable operation under certain reflux ratio; 2. the used flowmeter of prior art mostly is the GB product greatly, the flowmeter material all there is strict demand, therefore when detected fluid is Korrosionsmedium, often can not find the flowmeter of suitable material, and the utility model just can be dealt with problems with the simple processing of suitable material; 3. integral heat insulation is easy, therefore can use in high coagulating point medium.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1-shown in Figure 4, this refluence control device of rectifying column, this device mainly comprises slit gauge line 1, collecting tank 2, collecting tank 3, discharge nozzle 4, collecting tank ring flat-plate 5 and collecting tank base plate 6, and is subjected to liquid space by what collecting tank base plate 6, collecting tank ring flat-plate 5 and tower body inwall 8 constituted; Be provided with collecting tank base plate 6 in tower body inside, the outward flange of collecting tank base plate 6 and tower body inwall 8 are tightly connected, the inward flange of collecting tank base plate 6 and collecting tank ring flat-plate 5 are tightly connected, and collecting tank 2 is embedded among certain diameter opposite ends of collecting tank ring flat-plate 5 and with collecting tank ring flat-plate 5 and collecting tank base plate 6 and is tightly connected.Slit gauge line 1 is the two ends that have slit 1-1 in the middle of tube wall closed circle pipe fitting not, one group 5 the wide slit gauge lines 1 of different seams are arranged on the same straight line equally spacedly, pass collecting tank 2 bottoms and be tightly connected with collecting tank 2, the vertical lower of slit gauge line 1 is provided with the collecting tank 3 that does not seal at the top, its number of packages is consistent with slit gauge line 1, and the lower surface of the upper surface of collecting tank 3 and slit gauge line 1 maintains certain spacing.All be connected with discharge nozzle 4 in every collecting tank 3 bottoms, discharge nozzle 4 is connected with the valve 7 of controllable switch outside tower body.
Operation principle of the present utility model is: the liquid that flows down from condenser enters by collecting tank base plate 6, collecting tank ring flat-plate 5 and tower wall constitute be subjected to liquid space after, flow in the collecting tank 2, when the liquid level of liquid in the collecting tank 2 is higher than slit bottom figure and gets the bid timberline a, liquid flows in the slit gauge line 1 along slit, in flowing to collecting tank 3 under it from slit gauge line 1 bottom again, if the valve 7 that links to each other with discharge nozzle 4 is opened, the liquid that then flows into corresponding collecting tank 3 is drawn tower body, if the valve 7 that links to each other with discharge nozzle 4 is closed, then the full collecting tank of liquid storage 3 backs are overflowed from the top of collecting tank 3 and are back in the tower.Because reflux ratio is the ratio that is back to liquid measure and the liquid measure of drawing tower body in the tower, so at this device, the size of reflux ratio promptly is the ratio that overflows liquid measure summation with the liquid measure summation that flows out discharge nozzle 4 of collecting tank 3.
The control method of reflux ratio: with Fig. 1-Fig. 3 is example, and slit gauge line 1 has 5, and the slit designs on the gauge line becomes different width, is respectively S
1～S
5, the fluid flow of the slit gauge line 1 of flowing through only is directly proportional with slit width S, and the liquid of each slit gauge line 1 of flowing through all will flow in the corresponding collecting tank 3, will distinguish the called after valve with the valve of discharge nozzle 4 connections and corresponding slit gauge line 1
1～valve
5, then flow back to the summation ∑ S that liquid measure and pairing slit gauge line 1 slit of valve-off in the tower stitches wide S
CloseBe directly proportional, then flow out the summation ∑ S that the liquid measure of tower body and slit gauge line 1 slit that Open valve is corresponding stitch wide S
OpenBe directly proportional, therefore, can draw such conclusion: as long as liquid does not overflow and the corresponding collecting tank of Open valve discharge nozzle, the ratio that then refluxes is ∑ S
Close/ ∑ S
OpenSo, as long as with S
1～S
5Be designed to different values, can be combined into 32 kinds of backflow ratios from 0 to ∞.In like manner,, then can be combined into 16 kinds of backflow ratios if slit gauge line 1 amounts to 4, also promptly when slit gauge line 1 add up to n the time, the quantity that can be combined into backflow ratio is 2
nKind.
