Embodiment Construction

[0020] this invention figure 1 , figure 2 It is a schematic diagram of an on-line ultraviolet microwave combined digestion tank. In practical applications, the liquid inlet 6 is connected to various reagents, and the automatic sample injection control device transfers the sample, The digestion agent is extracted quantitatively and added to the closed digestion pool 3, and the entire sampling process can be automatically completed under the control of a predetermined program. When the sample to be digested enters the online UV-microwave combined digestion tank, the external microwave energy and the ultraviolet light emitted by the UV light source can pass through the outer wall of the digestion tank and directly act on the sample according to the needs, and the closed-type UV, microwave and UV-microwave combined Digestion, the digested sample enters the electronic condenser through the liquid discharge port, and is measured after temperature-controlled condensation. The autom...

Abstract

The invention discloses an online ultraviolet microwave combined digestion pool which consists of a microwave oven with an internally installed ultraviolet lamp and a closed style digestion pool arranged in the inner cavity of the microwave oven. The oven wall of the microwave oven is provided with a liquid inlet and a liquid outlet of digestion solution, and the middle part of the microwave ovenis provided with a rotating tray which is provided with the closed style digestion pool. The online ultraviolet microwave combined digestion pool is connected with a computer control part externally,provides an appropriate digestion technology for the online analysis of various detecting indexes in the fields of environmental monitoring, and the like and has the advantages of convenient operation, reliable performance, complete digestion, wide application, and the like. Processes of automatic sample introduction, digestion, cleaning, and the like can be finished on line in one step. The invention has the advantages of complete ultraviolet microwave combined digestion, low digestion temperature, convenient operation and reliable performance.

Description

technical field [0001] The invention relates to an on-line ultraviolet and microwave combined digestion tank, which belongs to the technical field of environmental monitoring sample pre-processing system, or the technical field of supporting equipment. Background technique [0002] At present, online analysis technology is widely used in the analysis and detection of various indicators in the field of environmental monitoring because of its characteristics of rapid measurement and real-time monitoring. In the detection process of various indicators, the pre-treatment (digestion) of the sample is very important, and the online digestion device adapted to the online analysis technology has been widely used accordingly. Single thermal digestion generally requires higher temperature and pressure, especially for some difficult-to-digest organic compounds such as organophosphorus, it is difficult to achieve the purpose of complete digestion, and the digestion is not complete. Sun...
