Furthermore, the feeding valve, the discharging valve, the sampling valve, the recycling valve and the nitrogen valve are DN20 screw thread stainless steel ball valves.
Furthermore, the range of the pressure gauge is-0.1-0.5 MPa.
Further, the direction of the feed inlet is opposite to the flow direction of the materials.
Furthermore, liquid level scales are marked on the sampling tank sight glass.
Further, the nitrogen making machine is a molecular sieve air separation nitrogen making machine.
The utility model discloses a theory of operation does: during normal operation, all valves in the sampling device remain closed. When needs are taken a sample to the decolored oil after refining, open feed valve, let the decolored oil after refining flow in the sample jar, after the decolored oil gets into the sample jar, observe the condition of decolored oil through the sample jar sight glass. After the sample volume satisfied the sample requirement, closed the feed valve, the internal pressure of sample jar was the negative pressure this moment, opened nitrogen valve and eliminated the negative pressure, observed the manometer simultaneously. When the index of the pressure gauge reaches 0MPa, the nitrogen valve is closed, the discharge valve is opened, and the sampling valve is opened at the same time, so that the taken-out decolored oil flows into the sampling container. After the sample, close the sample valve, open the recovery valve, let unnecessary decoloration oil flow in recovery jar, when no longer having the decoloration oil inflow in the recovery jar, close discharge valve and recovery valve. The de-bleached oil in the recovery tank can be mixed into the next batch of feedstock for refining.
The utility model has the advantages that:
(1) during the refining process, the equipment operation does not need to be stopped, and dynamic sampling detection can be carried out on the refined decolored oil at any time even if vacuum exists. Therefore, the operation is simple and convenient, and the problem that the sample cannot be taken under the vacuum state is solved.
(2) The utility model discloses set up the recovery jar at the end of equipment, both prevented that remaining destaining oil from remaining in the sample process from remaining in sample jar and the pipeline, influencing going on of next sample, also avoided leading to the waste of destaining oil because of the sample, destaining oil in the recovery jar can be mixed and refine in the raw materials of next batch.
