Marine petroleum pollution vertical analysis simulator

Abstract

The invention discloses a marine petroleum pollution vertical analysis simulator, which is composed of a simulator body, wherein the simulator body comprises a support frame and a sink, the sink is composed of at least two transparent organic glass tubes connected through a flange, the bottom of the sink is provided with a base integrated with the sink as a whole, the base is placed on the upper surface of the support frame, and the bottom of the support frame is provided with foundation bolts for leveling; the upper part of the sink is provided with a water inlet pipe with a water inlet control valve, the bottom of the sink is provided with a drainage pipe with a water outlet control valve, and the drainage pipe passes the support frame, the top of the sink is provided with a support plate, the support plate is connected with a connecting rod extending into the sink, the bottom of the connecting rod is connected with a wave making plate, the support plate is also provided with a drive motor, and the drive motor is provided with rotating blades for poking the connecting rod to enable the wave making plate to swing. The simulator disclosed by the invention can realize the study on longitudinal distribution of petroleum in seawater indoors, is simple in structure, convenient and quick, and safe and reliable.

Description

technical field [0001] The invention relates to a marine environment simulation device, in particular to a longitudinal analysis simulation device for marine oil pollution. Background technique [0002] As the main source of human transportation fuel today, petroleum has been exploited at a high level, which has caused a series of environmental problems. In addition to causing oil field soil pollution and other problems, it also causes water pollution in the process of mining, transportation and storage. Marine oil pollution, as the most serious form of marine environmental pollution, seriously threatens marine ecological security and indirectly affects human health through seafood. The issue of oil pollution has been listed by the United Nations in the "Major Agenda of the 21st Century". [0003] After an oil spill accident, oil will undergo a series of physical, chemical, and biological weathering processes in the marine environment, mainly including spreading, evaporati...

Problems solved by technology

Patents on simulation devices for marine oil spill analysis have been actively published at home and abroad (application numbers 200810211335.2, 200910105645.0, 201110377573, etc.), and many researchers have also designed water tanks to simulate oil-absorbing materials, biological agents, etc. Caruso, & Cappello, 2014; Hassanshahian, Zeynalipour, & Musa, 2014; Wang Lina, 2013), however, the existing patents and research can better study the residual oil and condensed residue floating on the sea surface. Due to the limitations of the device, it cannot be effectively carried out, and there are few studies. Faksness et al. conducted an analysis of petroleum components in polar seawater with a height of about 1m outdoors (Faksness&Brandvik, 2008), so it is of great significance to design a longitudinal analysis device that can be used in indoor experiments
