Abstract

A high temperature high pressure enclosed counteraction apparatus applied in chemical analyzing instrument and counteraction the method thereof. The apparatus is characterized in that: it comprises a counteraction pool, a compacting and fixing mechanism, an excess-temperature protecting device and a temperature sensor; the compacting and fixing mechanism includes a compaction knob, an inner knob,a spring, a pressure head, a fixing part, a guide rod, an upper portion high pressure electromagnetic valve, a lower portion high pressure electromagnetic valve, a fixed supporting side plate and a transparent protective cover; wherein, the compaction knob, the inner knob, the spring, the pressure head, the fixing part, the guide rod and the upper portion high pressure electromagnetic valve compose an upper compaction mechanism; the fixed supporting side plate and the transparent protective cover compose a central coupling and supporting mechanism; and the lower portion high pressure electromagnetic valve composes a lower counteraction pool pedestal.

Description

technical field [0001] The invention relates to a digestion device in chemical analysis instruments in the field of environmental protection, in particular to a high-temperature and high-pressure closed digestion device. Background technique [0002] The high temperature and high pressure airtight digestion device of the present invention is mainly used in chemical analysis instruments to realize high temperature and high pressure airtight digestion. The existing digestion heating methods are mainly divided into three types: electric heating, microwave heating and infrared heating. Because microwave heating and infrared heating instruments and equipment are relatively complex and relatively expensive, most of the on-line analytical instruments currently use electric heating. [0003] High temperature and high pressure digestion means high temperature closed digestion, which can speed up the reaction speed and improve the reaction efficiency. For example, in the determinati...
