Abstract
This invention discloses a microwave dispelling device which comprises forward pressure container, backward microwave emitting system and pressure sensor container with a safety valve and pressure release valve located on top of steel cylinder. Its inner layer is formed into anti-corrosive layer by various components of PTFE materials and construction plastic. The microwave emitting system is located on the back of the device, and the antenna of magnetron, the pressure sensor, electric heating tube go from the bottom of steel cylinder to the inner chamber of pressure container where there located sample and dispelling reagent tube. In tight pressure container, the sample can be processed by automatic device by the high temperature and pressure generated from microwave heating and electric heating.
Description
The present invention relates to a kind of instrument, a kind of being used for carried out pre-treatment to sample in the analytical chemistry field, makes it the specialized equipment of digest and decompose.
Chemico-analytic sample pre-treatments is a global problem, the effort that AC is long-term, and the prior art that is occurred is not generally accepted by the chemical analysis industry so far.Traditional Specimen eliminating method mainly is dry incineration method and wet type resolution method, uses till today as national standard method always.In the current prior art, utilizing micro-wave oven and pressure dispelling jar to be used in combination and clear up sample, is comparatively popular a kind of new technologies of nearly more than ten years.The MARS-5 type intelligent microwave high pressure sample-preparing system of U.S. CE M company development for example, patent (ZL942394143) the optical fiber pressure automatic control closed microwave digestion system of Shanghai microwave applications technical institute.So-called digestion system is a kind of small pressure jar and the household microwave oven group of having reequiped and together.This head tank, double-decker, skin are engineering plastics, internal layer is teflon (to call PTFE an in the following text) inner bag, has sealing gasket.Sample and acid reagent are inserted in the jar, make the interior supercharging of sealable tank reach the purpose of clearing up sample by microwave heating.The advantage of its maximum is that speed is exceedingly fast, finish the Specimen eliminating overall process about 20 minutes, but also be his critical defect, temperature and pressure sharply raises in several minutes, volume in jar only has 50 milliliters, and energy can not discharge, and easily produces the UHV (ultra-high voltage) phenomenon, High Temperature High Pressure causes the distortion of PTFE inner bag, and sealing gasket bursts apart.Simultaneously because the position difference of head tank in micro-wave oven, the energy difference that is absorbed, reproducibility of analysis results is relatively poor.So prior art is difficult for promoting, and fails during the last ten years to popularize, this series products also is like this both at home and abroad.
Purpose of the present invention, be to overcome the defective of current prior art, a kind of Specimen eliminating instrument is provided, combine with electrical heating with microwave heating, designed the inner bag that a kind of seal-off pressure container replaces micro-wave oven, cancellation pressure dispelling jar the glass test tube that sample and reagent are housed, places and clears up sample in the closed pressure vessel.Be actually the pressure vessel that the head tank of 50 milliliters of single volumes has been become about 15 liters big volumes, temperature and pressure is controlled in the lower scope, and the chemical reaction velocity of sample and reagent is slowed down, and the Specimen eliminating process is slowly stablized.
Technical solution of the present invention is, instrument is divided in two parts, and the front portion is a pressure vessel, and the rear portion is a microwave transmission system.Described pressure vessel, drum can also can be pressed nonstandard design of pressure vessels as the rectangle microwave burner hearth by the design of GB Steel Pressure Vessels.It is a double-decker, and skin is a steel design, and internal layer is that the molded inner bag of PTFE material membrane is made corrosion protective lining, and high-strength engineering plastic is done heat-insulation layer, has the pressure-bearing function concurrently.This cylindric Steel Pressure Vessels is placed with horizontal type.Described microwave launcher system, also comprise pressure sensor diagnostics, electric heater unit, blind controller system.The magnetron launched microwave enters airtight pressure vessel through waveguide, after starting microwave emission dress system, places sample and reagent in the glass test tube in the pressure vessel, clears up sample under high temperature, condition of high voltage.As run into the sample that is difficult to clear up, can use the heating of microwave heating and electrothermal tube simultaneously, instrument A.T.C and pressure.Maximum operating temperature is 180 ℃, and pressure is 1MPa to the maximum, can prevent that chemical reaction from causing that temperature, pressure sharply raise, and reach the purpose of clearing up sample lentamente.
The present invention improves magnetron, the antenna of magnetron appropriateness lengthening, and magnetron removes cooling fins, with aluminium matter water pipe seal welding, reaches very high radiating efficiency by tap water mobile, and magnetron can be worked continuously for a long time.
The present invention is an one with microwave heating and electric heater unit and pressure vessel group, microwave and electric heating double energy have been utilized, the rapid rising of control temperature, pressure, the sample in the glass test tube is being cleared up under the seal-off pressure container environment of term harmonization, is directly exposed in microwave radiation and the electric radiation field, accept energy even, handling safety, stable performance can not produce the UHV (ultra-high voltage) phenomenon because of chemical reaction, improve the quality of clearing up of sample, eliminated unsafe factor.
The present invention is described in further detail below in conjunction with accompanying drawing.
