Embodiment Construction

[0059] In order to make the description of the present invention clear, the implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0060] Such as Figure 5 As shown, the oil sludge phase separation content detection system based on the pyrolysis method mainly consists of an induction heating power supply, an induction heater, a temperature detection module, a controller, a condensation device, a measuring tube and an analytical balance. The DC 48V power supply is converted into a low-voltage and high-frequency induction heating power supply through inverter (DC / AC). The induction heater is used to place the container with pyrolysis sludge, specifically a copper crucible. Under the action of the induction heating power supply, an eddy current is generated in the hot copper crucible to heat up the oil sludge; the temperature detection module detects the temperature of the sludge sample in the induction h...

Abstract

The invention discloses a method for detecting holdup of split phases in oil sludge based on an induction heating technique and a measuring system. The detection method is based on the formation mechanism and physical-chemical characteristics of the oil sludge, the induction heating technique is adopted, the oil sludge is pyrolyzed according to the set heating curve, and the oil gas and water steam produced by pyrolysis are condensed and collected, and are sent into a metering cylinder; the oil and water in the metering cylinder are naturally separated, the volume of water at the lower layer is read via the scales of the metering cylinder, and the mass of the water is obtained by combining with density; the total mass of oil and water is weighed by an analytical balance, the mass of the water is deducted, and the mass of the oil is obtained; the mass of the oil and the mass of the water are deducted from the mass of the oil sludge, so as to obtain the mass of residue, thereby calculating the holdup of split phases in the oil sludge; by adopting the detection method, the holdup of split phases in the oil sludge can be simultaneously detected, the stored and transported oil sludge can be quickly detected within about one hour, and the detection absolute errors of the three phases are respectively smaller than 2%. The measuring system mainly consists of an induction heating powersupply, an induction heater, a temperature detection module, a controller, a condensing device and a metering test tube.

Description

technical field [0001] The invention belongs to the field of oil sludge component detection, and in particular relates to an induction heating technology-based oil sludge phase separation content detection method and a measurement system. Background technique [0002] Petroleum is an indispensable and important energy source in the industrial society. In the process of oil extraction, transportation and storage, oil sludge is inevitably produced due to deposition or pollution. These oil sludge formed during the production process cannot be directly used and are mostly discarded or incinerated. . The main components of sludge are oil and water, and it also contains a part of residue. The resource utilization of oil sludge can reduce the waste of resources, and at the same time avoid the pollution of oil sludge to the ecological environment. The rapid detection of the phase-separated content of sludge (including water content, oil content and slag content) can not only provi...
