Description
Technical field
The present invention relates to a kind of absorption plant that is used to measure gas content.
Technical background
Gas absorption is the key link that some gas contents are measured, and these gases comprise sulfuretted hydrogen, sulphuric dioxide, ammonia, formaldehyde etc.Some can react the content that the material that generates above-mentioned gas also can come the indirect determination material by the method for gas absorption, and the amount of the hydrogen sulfide gas that can produce by assaying reaction as the mensuration of sulfide in sediment or the water sample is determined the content of sulfide.
Gas absorbing device is the critical component that gas content is measured.When determined gas content was low, gas absorbed efficiency was often lower, absorb instability, and the amount of required absorption liquid was bigger, and it is undesirable to cause measuring effect.Traditional gas absorbing device generally is to improve gas absorbed efficiency by the method for the length that increases absorption tube, but because solution-air is short duration of contact, and the increase of absorption liquid consumption, effect improved not obvious.
The utility model content
Above-mentioned shortcoming at the conventional gas absorption device exists provides a kind of miniature, efficient, stable tower gas absorbing device.A kind of miniature tower gas absorbing device that is used for gas content mensuration comprises: ground hollow glass plug, escape pipe draft tube, dividing plate, absorption tube, porous breathable head, magnetic stirring apparatus; Described absorption tube is the cylinder that an end seals an end opening, and described ground hollow glass plug is arranged on the openend of draft tube, and draft tube and escape pipe all are inserted in the absorption tube by ground hollow glass plug; Be provided with some some through hole dividing plates that have in described absorption tube, draft tube is worn the bottom that described dividing plate is inserted into described absorption tube; The end that draft tube is inserted the absorption tube part also is provided with the porous breathable head; Magnetic stirring apparatus is arranged on the blind end place near absorption tube, and after miniature tower gas absorbing device assembling is finished, has certain distance between magnetic stirring apparatus and the porous breathable head.
Further, described draft tube, ground hollow glass plug, escape pipe, dividing plate are as a whole.
Further, the material of each ingredient of described absorption plant is acid and alkali-resistance, resistant material.
Further, the openend of described absorption tube is horn-like.
Further, described multilayer insulating panel be shaped as ball crown type, and after described absorption plant assembling was finished, its arc end face was towards the openend of described absorption tube.
Further, described several dividing plates are provided with in the absorption tube for uniformly-spaced contacting.
Further, described draft tube is arranged on the centre of described ground glass stopper.
Further, described multilayer insulating panel is shaped as tabular or wavy.
Miniature tower gas absorbing device disclosed in the utility model makes the gas of feeding pass through magnetic agitation, fully mixes contacting with absorption liquid; And multilayer insulating panel is set in absorption tube, increased solution-air duration of contact.By above-mentioned transformation to absorption plant, absorption plant disclosed in the utility model has effectively increased solution-air duration of contact and the contact area in the absorption plant under the condition that does not increase the absorption tube volume, realize that in absorption plant classification absorbs gas, thereby the raising gas absorbed efficiency reduces the absorption liquid consumption.And this is simple in structure for this device, working stability.

Embodiment
Following conjunction with figs. and specific embodiment are described in further detail the specific embodiment of the present invention.
Shown in accompanying drawing 1,2, the complete miniature tower gas absorbing device of a cover is made up of ground hollow glass plug 1, escape pipe 2, draft tube 3, dividing plate 4, absorption tube 5, porous breathable head 6, magnetic stirring apparatus 7.Absorption plant is processed by acid and alkali-resistances such as glass, teflon, resistant material, is subjected to the corrosion of corrosive gas or liquid to prevent absorption plant.Absorption tube 5 is the cylinder that an end seals an end opening, and its openend is horn-like, outwards expansion.Draft tube 3 and escape pipe 2 all are inserted in the absorption tube 5 by ground hollow glass plug 1.Also be provided with several dividing plates 4 on the part of draft tube 3 insertion absorption tubes 5, dividing plate 4 is fixed on the draft tube 3 along axially equidistant, the polyphone of draft tube 3, and dividing plate 4 is spherical, and its bottom surface diameter is slightly less than the internal diameter of absorption tube 5.After the installation, the hat cambered surface of dividing plate 4 balls also is provided with several small through hole towards ground hollow glass plug 1 on the dividing plate 4 of dividing plate 4.The end that draft tube 3 is inserted absorption tube 5 parts also is provided with porous breathable head 6.Magnetic stirring apparatus 7 is arranged on the blind end place near absorption tube 5, and after miniature tower gas absorbing device assembling is finished, has certain distance between magnetic stirring apparatus 7 and the porous breathable head 6, does not contact between the two.Draft tube 3, ground hollow glass plug 1, escape pipe 2, dividing plate 4 can be processed into an integral body, are installed together after also can processing respectively.
During use, at first add absorption liquid in absorption tube 5, the volume of absorption liquid accounts for 70% of absorption tube volume.Then, silicone grease is smeared at 5 ground places at absorption tube, and will have escape pipe 2, the hollow glass plug that is equipped with the draft tube 3 of dividing plate 4 inserts in the absorption tube 5, the interior ground of absorption tube 5 contacts with the outer grinding port of ground hollow glass plug 1, under the effect of silicone grease, absorption tube 5 and ground hollow glass plug 1 are realized hermetic seal in the back of combining closely.Then, slowly feed determined gas by draft tube 3, determined gas imports to absorption tube 5 bottoms through draft tube 3 and porous breathable head 6, under the stirring of magnetic stirring apparatus 7, increased the contact area of tested gas and absorption liquid, gas mixes fully with absorption liquid, can strengthen assimilation effect.The a part of gas that is entered in the absorption tube by the outside is absorbed in well-mixed process, there is not absorbed gas from the bottom-up motion in the bottom of absorption tube 5, arrive dividing plate 4, because the hat cambered surface of dividing plate 4 can be in the lower camber side place enrichment of dividing plate 4 when tested gas is up towards ground hollow glass plug 1.In addition, also because dividing plate 4 is provided with some small through hole, when gas moved arrival dividing plate 4 from bottom to top in absorption liquid, under the acting in conjunction of surface tension and dividing plate 4, gas further increased in 4 times hold-up times of each dividing plate at admission pressure, small through hole place liquid; So increase the hold-up time of gas in absorption tube 5, improved gas absorbed efficiency.Like this, bottom-up, gas effect through multilayer insulating panel 4 in motion process is absorbed by classification.At last, unabsorbed a small amount of gas is discharged through escape pipe 1.
Miniature tower gas absorbing device structure in the present embodiment substantially with embodiment 1 in identical, its difference is that dividing plate 4 is fixed on the sidewall of absorption tube 5.
Partition shape among above-mentioned two embodiment also can be the flat board that has some small through hole, wave plate etc.
This device is further specified as example with the experiment of using tower absorption plant to carry out hydrogen sulfide absorption: the absorption tube volume is 110mL, and internal diameter is 30mm, and the absorption liquid measure is 70mL, and the quantity of dividing plate is 4, and through-hole diameter is 1.5mm on the dividing plate.
With the NaOH of 0.5mol/L as absorption liquid.Do the carrier gas of sulfuretted hydrogen with high purity nitrogen, when concentration of hydrogen sulfide is the mg/L magnitude, when the nitrogen flow is 20-40mL/min, the absorptivity of sulfuretted hydrogen greater than 90%, 3 average relative error less than 4.5%.
