Viewing mirror for implementing in situ optical observation in high-temperature highly pressurised liquid entironment and applications

Abstract

The invention relates to a lens structure, in particular to the lens structure which has safe and reliable sealing, realizes the in-situ optical observation under a high-temperature and high-pressure fluid environment (the maximum temperature and the maximum pressure can be 350 DEG C / 20MPa) as well as the application thereof, and solves the sealing and the visual (observation) problems under the high-temperature and high-pressure environment. The lens structure is assembled on an autoclave, and is composed of a pressure cap, a butterfly-shaped washer, a flat washer, a lens, an O-shaped ring, a lens barrel, a lens mount, a graphite washer, a clamping ring and a gland. When assembled, the components such as the pressure cap, the washers, the lens, and the like extend into the autoclave through the lens mount; then the gland is screwed on the lens mount until clamping the clamping ring and the washers tightly. In order to ensure that the lens barrel structure can stably work for a long time under the high-temperature fluid environment and can realize the high-quality in-situ optical observation, a single-crystal sapphire wafer with high high-temperature strength, good corrosion resistance and excellent optical performance is taken as the lens material. Besides, the invention increases the luminous flux through designing the lens barrel into a conical structure, thereby facilitating the realization of the in-situ optical observation.

Description

technical field [0001] The invention relates to a sight glass structure, in particular to a sight glass structure with safe and reliable sealing, which can realize in-situ optical observation in a high-temperature and high-pressure liquid environment, and an application thereof. Background technique [0002] In chemical, food, pharmaceutical fields and laboratories, some reactions are often carried out in a liquid environment with high temperature and high pressure. Due to the harsh reaction conditions, the monitoring of the reaction process can usually only be achieved by indirect means, and it is difficult to obtain direct and reliable information, which makes direct in-situ observation technology very necessary, and optical in-situ observation is one of them. important kind. In order to achieve optical in-situ observation in a high-temperature and high-pressure liquid environment, there must be a detection window leading into the airtight reaction vessel, and opening a d...
