Balance pressurization type high efficiency digestion apparatus

Abstract

The invention relates to a balance pressurization type high efficiency digestion apparatus, which comprises a pressure vessel, a pressurization unit, a heating block, a heating resistance wire, an air cooling pipeline, an inflator, a sample pipe and outlet pipe; the pressurization unit and the pressure vessel are communicated, and the heating block is equipped in a pressure vessel, and the heating resistance wire and the heating block are connected, and the air cooling pipeline is in the heating block, and one end of the air cooling pipeline is connected to the inflator equipped outside the pressure vessel, and the other end extends to the outside part of the pressure vessel, and the sample pipe is inserted on the heating block, and one end of the outlet pipe is equipped in the pressure vessel, and the other end extends to the outside of the pressure vessel. Compared with the prior art, the invention employs a method for digesting many samples simultaneously in an integral pressurization container, thereby completing digestion front treatment of the sample, and ensuring accuracy of the test result under the same condition, and a filtering processing can be obtained by gas generated in digestion; the invention has the advantages of rapid, safety, environmental protection and energy saving.

Description

technical field [0001] The invention relates to a digestion device, in particular to a balanced pressurized high-efficiency digestion device. Background technique [0002] In qualitative or quantitative chemical analysis, the analysis of certain elements can be pretreated by a digestion method, that is, heating in the presence of acidic media and oxidants to digest organic matter, so that the measured elements can be transformed into simple inorganic substances. cationic form. Digestion can avoid some interference and ensure the accuracy of test results. There are usually two ways of digestion: [0003] 1. Conventional digestion, the test sample is placed in a glass beaker, and after adding the digestive agent, it is usually heated by an electric furnace or an electric heating plate. The disadvantage is that the solution not only causes a large amount of heat loss when it evaporates, but also easily causes the solution to bubble and overflow, resulting in the failure of th...
