Abstract
The utility model provides a bubble removal device for continuous flow analysis. The bubble removal device comprises a fluid conveying pipe, wherein a to-be-detected solution inlet is formed in one end of the fluid conveying pipe, and a to-be-detected solution outlet is formed in the other end of the fluid conveying pipe; a peristaltic pump, a waterproof ventilating pipe, a check valve and a circulating pool are arranged on the fluid conveying pipe in sequence along the flowing direction of fluid; micro holes for enabling gas to be discharged conveniently are formed in the pipe wall of the waterproof ventilating pipe. Due to the adoption of the bubble removal device disclosed by the utility model, when a to be detected solution with bubbles enters the waterproof ventilating pipe and the check valve through the fluid conveying pipe, pressure in the waterproof ventilating pipe is higher than external atmospheric pressure because certain system pressure is required to keep the switched-on state of the check valve. Under the action of the pressure, the to be detected solution enters the circulating pool, and the bubbles in the to be detected solution are removed through the waterproof ventilating pipe, so that bubble removal operation is realized. The bubble removal device for continuous flow analysis is simple in structure and convenient to operate, and easily fulfills the aim of removing the bubbles from liquid to be detected.
Description
Technical field
The utility model relates to a kind of bubble removal device, relates in particular to a kind of Continuous Flow Analysis bubble removal device.
Background technology
Continuous Flow Analysis conventional detection method while being water quality Flow Injection Analysis, have simple to operate, analysis speed is fast, precision is high, be easy to the advantages such as automatic continuous analysis, in environment water sample analysis, there is consequence, be widely used in the detections such as inorganic ions, metallic ion, chemical oxygen demand (COD).
In Continuous Flow Analysis process, need to carry out optical detection to solution to be measured, and calculate the concentration of determinand by shading value.In general,, under the driving of peristaltic pump, the solution to be measured after colour developing circulates by the road behind pond and detects.Solution to be measured in pipeline is because the heating in process color, ultraviolet irradiation, chemical reaction etc. tend to produce bubble.The existence of bubble, makes to exist in solution the interphase of air and solution, thereby causes light by refraction effect occurs, and produces rub-out signal.Meanwhile, bubble reduces solution net thickness, affects measurement result.Therefore, the solution to be measured in test in pipeline circulates before pond, need to remove the bubble in solution to be measured.
Summary of the invention
The purpose of this utility model is to provide a kind of Continuous Flow Analysis bubble removal device, to solve the problem that is not easy to remove the bubble in solution to be measured existing in prior art.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme to realize:
A kind of Continuous Flow Analysis bubble removal device, it comprises fluid delivery tube, one end of described fluid delivery tube is solution entrance to be measured, the other end is taphole to be measured, on described fluid delivery tube, be provided with successively peristaltic pump, waterproof ventilation tube, retaining valve and flow cell along fluid flow direction, the tube wall of described waterproof ventilation tube is provided with is convenient to the micropore that gas is discharged.
To the further improvement of technique scheme, the internal diameter of described micropore is 0.5-15.0mm, and external diameter is 1.0-20.0mm.
To the further improvement of technique scheme, described fluid delivery tube is polyfluortetraethylene pipe or silicone tube.
To the further improvement of technique scheme, described waterproof ventilation tube is polyfluortetraethylene pipe.
To the further improvement of technique scheme, the entrance and exit of described peristaltic pump is connected with described fluid delivery tube by pump line respectively.
Compared with prior art, the useful technique effect the utlity model has is: adopt bubble removal device described in the utility model, when the solution to be measured with bubble is in the time that fluid delivery tube pumps into waterproof ventilation tube and retaining valve by peristaltic pump, need certain system pressure owing to maintaining retaining valve opening, after only having fluid delivery tube and waterproof and breathable overpressure to acquire a certain degree, just can make retaining valve open, therefore the pressure of waterproof ventilation tube inside can be greater than external atmosphere pressure.Under the effect of waterproof ventilation tube internal pressure, the bubble in solution to be measured is discharged by the micropore of waterproof ventilation tube, and solution to be measured enters into flow cell, realizes the disengaging operation of bubble.The utility model is simple in structure, easy to operate, is easy to realize the bubble removal object in testing liquid.
