Embodiment 1

[0035] Please refer to Figure 1 to Figure 4 , are respectively the structural schematic diagram of Embodiment 1 of the device for evaluating the oil absorption performance of the particle adsorption material of the present invention; the structural schematic diagram of the control rod of the present invention; the structural schematic diagram of the upper baffle plate of the oil baffle assembly of the present invention; Schematic diagram of the structure of the lower baffle. As shown in the figure, the present invention proposes an evaluation device for the oil-absorbing performance of granular adsorption materials, including an adsorption column 1, an oil retaining plate 4, an oil collection container 5, a control rod 6, and a water heating container 7. Such as figure 1 As shown, the adsorption column 1 has a scale mark and is vertically arranged. The adsorption column 1 has an upper port and a lower port. The upper port of the adsorption column 1 is provided with a top cov...

Embodiment 2

[0064] Please refer to Figure 5 , is a schematic structural diagram of Embodiment 2 of the present invention. In this embodiment, the same components as those in Embodiment 1 use the same reference numerals.

[0065] Such as Figure 5 As shown, the main structure, working principle and beneficial effects of the second embodiment of the present invention are the same as those of the first embodiment, and will not be repeated here. The only difference is that the second embodiment is not provided with a water heating container. When the oil product used in the detection is diesel oil, it is not necessary to heat it, so the device removes the water heating container. In order to fix the device, a bracket 100 is provided, and the adsorption column 1 is inserted through the socket of the bracket 100 , and fixed with the bracket 100 through the clamp 10 .

[0066] When in use, the second embodiment adopts the following steps:

[0067] Step 1: Add the granular adsorbent that has...

Abstract

The invention discloses a device for evaluating the oil absorbency of a granular absorbing material. The device comprises an vertically-arranged adsorption column with an upper port and a lower port; a top cover with an oil inlet is arranged on the upper port; a bottom cover with an oil outlet is arranged on the lower port; an oil baffle group is arranged in the adsorption column; the adsorption column is divided into an upper oil storage region and a lower adsorption region by the oil baffle group; the oil baffle group consists of a disc-shaped upper baffle and a disc-shaped lower baffle which are stacked symmetrically; oil guide holes corresponding to one another are formed in the upper baffle and the lower baffle; both the upper baffle and the lower baffle can rotate opposite around the respective center axes; and an oil collection container is connected with the oil outlet of the bottom cover on the lower end of the adsorption column through an oil drain pipe. The device provided by the invention can measure the instantaneous oil absorption rate, oil absorption amounts at different times, and final saturated adsorption amount, can greatly improve the measurement precision of oil absorption parameters and is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of oil and gas field environmental protection in the petroleum industry, in particular to a device for evaluating the oil absorption performance of particle adsorption materials. Background technique [0002] Because oil pollution is extremely destructive to ecology and the environment, the use and transportation of crude oil and various oil products have become an integral part of modern life. Corrosion and perforation of oil pipelines and third-party construction damage have led to frequent oil spill incidents of various scales, which have brought serious pollution to the ecological environment such as soil, water (ground water / surface water), plants, and marine organisms, and have caused great public concern. attention. In order to prevent the pollution of the environment caused by the spread of oil leakage, while developing a large number of excellent oil-absorbing materials, how to select materials wit...
