Abstract
The utility model relates to an upright apparatus for atomizing system, which breaks the horizontal forward spray mode following more than thirty years and adopts the upright atomizing chamber. An atomizer and an acetylene spray pipe are placed 'vertically', and fog droplets follow the Bernoulli's principle and are conveyed stably in the expanding and diffusing mode, having small fog droplets, adequate mixing and smooth waste liquid draining. Therefore, the upright apparatus for atomizing system not only ensures the advantages of currently popular atomizing system, and the utility model also has the advantages of less noise, flexible operation, simple structure, low cost, lower memory effect, convenient demount and safety.
Description
The utility model relates to a kind of atomization system and device, belongs to field of analytic instrument, is mainly used in atomic absorption spectrophotometer (AAS).
Atomic absorption analysis is the eighties advanced person's that obtains developing rapidly a instrument analytical method, and principle is to utilize the ground state free atom that the resonance absorption of radiation energy is come concentration of element in the working sample.Therefore, the atomization system is the key device of instrument.The height of atomic absorption signal, noise and memory effect etc. depend on the quality of atomization system and device to a great extent.Since this method of the fifties was come out, manufacturing firm all attached great importance to research, design, the improvement of atomization system architecture both at home and abroad.A desirable atomizing apparatus should be: the nebulization efficiency height, droplet is little, refinement good, noise is low, aerosol mixes fully, droplet is carried steadily, memory effect is little and atomization degree height.
At present, domestic and international popular atomization system and device is as PHILIPSPU9400AAS(1987 BCEIA showpiece), form by atomizer, spray chamber, burner, be known as＜give hybrid atomization system〉(seeing accompanying drawing 2), come down to a kind of level injecting type device forward.In order to guarantee that droplet is little, refinement good, mixing is abundant, fog chamber's length can not be too short, is added with baffle plate (flow spoiler) and makes the fog chamber one small inclination (～5 ° of angles) be arranged to drain waste liquid toward contact.This way is to be cost with sacrificial section droplet (desensitization), and cause bigger memory effect inevitably, when especially alternately inhaling the big element of bigger sample of spray concentration, viscosity differences and memory effect, will cause analytical precision significantly to descend.
The purpose of this utility model just is, seeks a kind of processing of being convenient to, and desensitization not can effectively be eliminated the new atomization system and device of memory effect.
The utility model has been broken the popular means that followed for three more than ten years, takes the vertical type spray chamber, the structure that atomizer and acetylene jet pipe are laid with respect to spray chamber " vertically ", and utilize the Bai Nuli principle to transport droplet dexterously with the expansion diffusion way.
Structure of the present utility model can be by the embodiment explanation shown in the accompanying drawing 1.Spray chamber 1 is made of upright hollow cylinder, can be metallic article, also can make with engineering plastics.The hollow cylinder upper inside wall can be the face of cylinder, also can be circular conical surface, also can make the surfaces of revolution of other curve.The hollow cylinder bottom is equipped with atomizer 2, atomizer 3 and acetylene jet pipe 4 respectively and explosion-proof plug is housed.Atomizer 2, atomizer 3 and acetylene jet pipe 4 are mutually hexagonal angle in the projection of surface level.Atomizer 2, atomizer 3 and acetylene jet pipe 4 can have a little elevation angle.
The principle of work and the course of work: high-speed air forms negative pressure from pneumatic nebulizer 2,3 ejections at spout, and sample solution is vaporific ejection through kapillary by spout, and the little ball in the place ahead (collision ball) is with the further refinement of droplet; Acetylene gas is by 4 ejections of acetylene jet pipe.Because they are hexagonal angle with " level " shape and lay, and the little elevation angle that makes progress is arranged, air (combustion-supporting gas), acetylene (combustion gas), droplet are here fully mixed, and are constantly upwards transported with the expansion diffusion way as a result.Because spray chamber is upright, inwall is cone, according to fluid mechanics Bai Nuli principle, central authorities flow velocity greater than around flow velocity, make droplet upwards form " centre gangway " in the transport process in the diffusion of expanding: mist drips (signal) and enters flame through centre gangway, attaches at inwall around big droplet (noise) then is diffused into.Being waste liquid bottom the big droplet that the effect of gravity is gathered inwall flows to rapidly drains.
Structure of the present utility model has guaranteed fully that atomizing efficient height, droplet are little, good in refining effect, droplet is carried steadily, aerosol mixes fully, thick, thin droplet obtains effective separation, the atomization degree is high characteristic, thereby makes the instrument have higher sensitivity, precision and signal to noise ratio. Because uprightly lay the fog chamber, waste liquid is drained unimpeded, and therefore, the memory effect is very little. It is simple in structure, and processing has reduced cost easily.
Structure usage comparison of the present utility model is flexible. Only use an atomizer during conventional analysis, use simultaneously two atomizers can make instrument increase new function. During such as another atomizer spray gas, can reach change combustion help than purpose; When spraying blank solution, can reach the purpose of dilute sample; Can suppress during the spraying solvent to disturb or carry out interference test, also can directly carry out standard addition method, hydrogenization method is measured, and analyzes also very convenient to flammable sample (oil). If adopt engineering plastics to manufacture, also can improve corrosion resistance.
The utility model also can be used for ICP emission spectrometer torch guard system, also can be used for other and requires the low atomising device of memory effect.
