Abstract
The utility model discloses an environment-friendly sample digestion device, which comprises a temperature control instrument (1), an electric heating furnace (3), a heat-conducting furnace cavity (4), a digestion pipe (5), an absorbing bottle (11) and a water spray vacuum pump (13). According to the device, toxic gas generated in the digestion process is absorbed by the absorbing bottle, so that the problem that the atmosphere or a water body is polluted by toxic gas released in a traditional digestion process can be solved. The device is convenient to use and safe, achieves the effect of environment protection, and can meet the need on sample digestion operation.
Description
Technical field
The utility model relates to a kind of environment-friendly type sample and disappears and boil device, is applicable to that sample disappears to boil operating process, belongs to sample analysis preconditioning technique field.
Background technology
Sample disappears to boil in scientific research fields such as food analysis, soil analysis, plant component analyses and has a wide range of applications.Because nitrogen, phosphorus great majority in the samples such as food, soil, plant exist with organic, sample disappears through the concentrated sulphuric acid and oxygenant and boils, the oxidized decomposition of organism, and organic nitrogen and phosphorus change into ammonium salt and phosphate, disappear and boil liquid behind constant volume, can be used for the quantitative of elements such as nitrogen, phosphorus.But in the process of boiling that disappears, can produce a large amount of toxic and harmfuls, traditional method is many to be diffused into it in atmosphere or to adopt water-jet pump to be absorbed the back by water in its suction water and discharge in the body of intaking by ventilating kitchen, will form the pollution to environment like this, adopt the environment-friendly type sample to disappear to boil device then the acid waste gas that produces in the process of boiling that disappears can be absorbed by alkali lye and carry out harmless treatment, reached the purpose of environmental protection.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, uses easy to operately, and the environment-friendly type sample that is easy to apply disappears and boils device.
The technical scheme that the utility model is taked is, sample heating disappears and boils device and be made up of temperature controller, temp probe, electric furnace and heat conduction furnace chamber, exhaust gas absorption device comprises absorption bottle, rubber plug, water-jet pump, and wherein sample heating disappears and boils device and be connected with wireway by connecting duct with exhaust gas absorption device.
Described water-jet pump is connected with absorption bottle by connecting duct, and wherein water-jet pump can produce negative pressure.
Described wireway is deep from 3-5cm place, absorption bottle bottom, and gas outlet is deep from 3-5cm place, absorption bottle top.
The heating of described sample disappears and boils in the device disappearing on the electric furnace and boil pipe and boil the pipe lid and closely cooperate with the glass ground joint form with disappearing.
Disappear at sample and to boil, sample and chemical reagent are placed into to disappear and boil in the pipe, by electric furnace and heat conduction furnace chamber sample is heated, and the temperature by temp probe and temperature controller control heating.Formed negative pressure was boiled pipe with it from disappearing and is drawn into the absorption bottle when sample work by water-jet pump at the waste gas that produces in boiling of disappearing, and by wherein absorption liquid absorption.
Description of drawings
Fig. 1 boils schematic representation of apparatus for the environment-friendly type sample disappears.
Embodiment
As shown in the figure, sample of the present utility model heating disappears and boils device and be made up of temperature controller 1, temp probe 2, electric furnace 3 and heat conduction furnace chamber 4, exhaust gas absorption device comprises absorption bottle 11, rubber plug 10, water-jet pump 12, and wherein sample heating disappears and boils device and be connected with wireway 8 by connecting duct 7 with exhaust gas absorption device.
Described water-jet pump 12 is connected with absorption bottle 11 by connecting duct 7, and wherein water-jet pump 12 can produce negative pressure.
Described wireway 8 is deep from 3-5cm place, absorption bottle 11 bottom, and gas outlet 9 is deep from 3-5cm place, absorption bottle 11 top.
The heating of described sample disappears and boils in the device disappearing on the electric furnace 3 and boil pipe 5 and boil pipe and cover 6 and closely cooperate with the glass ground joint form with disappearing.
Disappear at sample and to boil, sample and chemical reagent are placed into to disappear and boil in the pipe 5, heat by electric furnace 3 and 4 pairs of samples of heat conduction furnace chamber, and disappear by temp probe 2 and temperature controller 1 control and to boil the temperature of heating.The waste gas that sample produces in the process of boiling that disappears during by water-jet pump 13 work formed negative pressure it boiled pipe 5 be drawn into the absorption bottle 11 from disappearing, and absorbed by absorption liquid wherein, realize harmless treatment.
