Intelligent environment-friendly mercury injection rock core treatment device

Abstract

The invention provides an intelligent environment-friendly mercury injection rock core treatment device, which comprises a gas cylinder, wherein a nitrogen generator is connected with the gas cylinder, and is sequentially connected with a high-temperature quartz tube and a condenser through a first pipeline, the output end of the condenser is respectively connected with a collecting bottle and thehigh-temperature quartz tube, the condenser is connected with the high-temperature quartz tube through a second pipeline, a diaphragm pump is arranged on the second pipeline and connected with the high-temperature quartz tube and a purifier, the purifier is connected with the collecting bottle, the collecting bottle is connected with a mercury concentration detector, and the nitrogen generator, the high-temperature quartz tube, the purifier, the diaphragm pump and the mercury concentration detector are all electrically connected with an electric control cabinet. According to the intelligent environment-friendly mercury injection rock core treatment device, cyclic utilization of inert gas is achieved, a large amount of cost is saved, and multi-stage continuous distillation desorption, purification recovery, automatic environment-friendly standard intelligent judgment and automatic control over tail gas standard emission of high-temperature distillation desorption mercury vapor are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an intelligent environmental protection treatment device for mercury injection rock cores. Background technique [0002] The pore structure distribution and characteristic parameters of geological core porous media are key indicators for evaluating the quality and classification of source, reservoir and cap rocks. Although there are many methods for obtaining pore structure and characteristic distribution parameters, such as mercury injection capillary pressure method, semi-permeable partition capillary pressure method, centrifuge capillary pressure method, cast thin section statistical method, X-ray CT scan inversion method, nuclear magnetic resonance fluid saturation research method, but the current mercury injection capillary pressure method is still the fastest Reliable, complete parameters, convenient for systematic comparison, and many irreplaceable advanta...

Problems solved by technology

[0003] According to the hazardous waste management regulations, the discarded rock cores after mercury injection cannot be discarded casually, and must be safely and properly sealed for storage. In view of the development of dangerous goods transportation management regulations, it is difficult for general enterprises to obtain the above two qualifications at the same time, so they can only adopt the method of temporary storage for on-site management. Therefore, it greatly hinders the timely and smooth development of related research and production on mercury injection experiments At present, the mercury-containing waste in most mercury injection laboratories adopts the laboratory self-temporary storage strategy. The large amount of waste storage has brought huge risks and challenges to the environmental protection responsibility of each unit. In the event of fire, flood, etc. Other accidents, resulting in the leakage of mercury pollutants or a large amount of volatilization exposure, the degree of harm of the secondary disasters is unimaginable
