In a manner described forward appendix, feed line, product conveying pipe and reverse appendix are connected between each container,
The pipeline that can make conveying liquid contacts with the liquid in each container, and guarantees to carry the pipeline of gas and the air in each container
Contact, does not contacts with the liquid in each container, forms the pressure reduction between each container, controls the flow direction and the flow velocity of liquid.
With specific embodiment, assembly of the invention is described further below in conjunction with the accompanying drawings.
Fig. 2 show the liquid charging stock chemical reaction equipment of three Liquid ingredient containers, but signal is only to hold with three raw materials
The structure of this chemical reaction equipment as a example by device, and the present invention is not limited merely to three material containers, it goes for two
More than individual, or the similar injection mode more than three kinds of material containers, at the liquid of three Liquid ingredient containers of Fig. 2 signal
In raw material chemical reaction equipment, only arrange each on the pipeline of conveying malleation air pump P21 and negative pressure air pump P22 control gas
Air shut-off valve V21-V25, and carry and on the pipeline of liquid charging stock or product, be all not provided with valve or liquid pump.When needs by
Certain liquid adds certain reactor to, it is only necessary to injects barotropic gas on the top of raw material liq and just can force the fluid into pipe
Road flows to be had in certain reactor of negative pressure, completes this transmitting procedure.So, pump and valve departing from and chemical principle
The contact of material, thus greatly reduce the corrosion to valve and pump, decrease pollution product brought because of corrosion.
In Fig. 2, owing to imposing negative pressure in the reactor, other raw material liq bottles being connected with reactor, also due to pressure reduction
A small amount of liquid outflow occurs, until the negative pressure on these raw material liq bottle tops is equal to the negative pressure in this segment pipe, this misoperation
Just can stop.In order to avoid this phenomenon produces, present invention employs and be not required to above the raw material liq bottle injected, also carry
Supply a subnormal ambient, so due to gas between these stock bottles (tank) and this segment pipe connecting this stock bottle (tank)
Pressure balanced, does not has pressure reduction, thus avoids this misoperation, here it is arrange negative pressure air pump P22 and reverse appendix
Effect.
After a reaction unit design typification, the length physics of its pipeline and geometric parameter have been fixed, according to fluid force
Its present principles learned, the liquid flow velocity in pipeline somewhere is proportional to the pressure reduction (including difference in height) in two ends, is inversely proportional to pipeline
Resistance to liquid, therefore can use the empirical equation of approximation to measure the flow rate of liquid in fixing pipeline, and then
Calculate the fluid flow within certain period, thus flow is control effectively.
Empirical equation can be simplified as:
V=K × Δ P/ ρ
In formula, V is flow rate of liquid, and Κ is the flow parameter of this passage, and Δ P is pressure reduction, and ρ is the resistance of ducting.Certain pipeline one
Denier design determines, in the case of liquid used is also determined, then Κ and ρ can be by estimation and actual measurement determines,
In the case of pressure reduction change is little, its parameter is also fixed number.So when practice, can be simply by control
Pressure differential deltap P of gas, it is possible to control the flow velocity of liquid.Further by controlling the time of liquid flowing, thus reach to control
The purpose of flow.
The chemical reaction equipment of the present invention is particularly suitable for transmission range short (generally less than 10 meters, or equipment oneself height
The pressure reduction caused is less than the device of 1 atmospheric pressure), liquid volume is little (less than several cubic metres), based on liquid charging stock
Small chemical synthesizer in.Other devices need additionally to increase the parts of other necessity.
Embodiment:
For the use state of the chemical reaction equipment of the experimental verification present invention, under internal security state, practice is in certain
Plant in radiopharmaceutic synthesis, owing to, in this radiopharmaceutic building-up process, needing use to have severe corrosive
Learning reagent, relatively strong to the corrosivity of valve and pump class inner chamber, pipe section, because being worth the highest, can be taked the most resistance to
Corrosion material, it is also possible to avoid above-mentioned problem, but use directly by valve and the pump of liquid, it is necessary to often change
These equipment, thus result in maintenance inconvenience, the problem that cost is too high.After using the chemical synthesizer of the present invention, this
Problem has obtained adequate solution.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, and appoints
How those familiar with the art is in the technical scope of present disclosure, the change that can readily occur in or replacement, all
Should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection domain of claims
It is as the criterion.
