A core oil washing instrument capable of automatic sampling and detection

Abstract

The invention discloses a core oil washing instrument capable of automatic sampling and detection, belonging to the field of core oil washing instruments. A core oil washing instrument capable of automatic sampling and detection comprises an oil washing instrument bracket whose upper end is fixedly connected There are solvent chambers, ultrasonic control systems and electrical control systems. A unique sampler can be installed in the core chamber, which is divided into multiple layers, and an oil-in-water sensor is installed in the sampler. Every time it is cleaned, the sample is stored in one of the layers. Stored in multiple layers, after sampling, use the oil in water sensor to automatically detect each layer, and automatically alarm when the requirements are met, indicating that the crude oil in the core has reached the standard, and there is no need to sample once every time it is cleaned, reducing the number of sampling operations. The workload of the staff is small, and the sample detection can be carried out directly in the sample storage layer to ensure that the entire experiment is in a sealed environment, so that the organic solvent vapor will not leak and affect human health.

Description

technical field [0001] The invention relates to the field of core oil washing instruments, in particular to a core oil washing instrument capable of automatic sampling and detection. Background technique [0002] The core oil washing instrument is an ultrasonic rapid oil washing device. When using it, put the sample into the core basket and put it into the core chamber together. Add an organic solvent with a strong ability to dissolve crude oil into the solvent chamber, and heat it to its boiling point to evaporate, and the vapor rises. Entering the condensation chamber, the steam condenses and drops into the liquid collection chamber. At this time, the liquid inlet solenoid valve is normally open, and the liquid outlet solenoid valve is normally closed. Therefore, the liquid in the liquid collection chamber directly flows into the core chamber and soaks the core. When the liquid in the core chamber fills the core chamber (as can be seen from the liquid level gauge in the li...

AI Technical Summary

Problems solved by technology

[0003] However, sampling is required after each cleaning, or multiple sampling is required, and it is cumbersome to perform detection and analysis after each sampling, and the core chamber needs to be opened for each sampling, which will cause leakage of organic solvent vapor and affect human health
