Abstract
The utility model relates to an oil discharge system for a liquid collection tank of a diesel hydrogenation compressor, and mainly solves the problem that in the prior art, an oil recovery pipeline is clogged since the liquid collection tank is blocked by dirty oil, and the clogged part is difficult to handle. The oil discharge system is characterized in that the middle of the liquid collection tank (1) is connected with an air leakage incoming material pipeline (3); the bottom of the liquid collection tank is connected with a dirty oil recovery pipeline (9); the dirty oil recovery pipeline is connected with a dirty oil collection tank (10); the top of the liquid collection tank is connected with a torch removing pipeline (7); the torch removing pipeline is connected with a torch tank (11); an air leakage recovery valve (2) is connected onto the air leakage incoming material pipeline (3); an oil drain valve (8) is connected onto the dirty oil recovery pipeline; a one-way valve and a torch valve (6) are connected onto the torch removing pipeline; the front part of the one-way valve on the torch removing pipeline is connected with a nitrogen line (4); a one-way valve and a nitrogen valve are connected onto the nitrogen line. The oil discharge system has the advantages that oil is discharged fast to enable the liquid collection tank to return to the normal operations state, and the compressor is guaranteed to run stably.
Description
Technical field
The utility model relates to a kind of liquid collecting tank oil draining system in petrochemical industry, particularly a kind of diesel oil hydrogenation compressor liquid collecting tank oil draining system.
Background technique
During petrochemical industry is produced, liquid collecting tank is the visual plant of diesel oil hydrogenation compressor " leakage-gas recovering system ", reclaims the lubricant oil of taking out of in gas leakage in tank, and gas phase is discharged from liquid collecting tank deck simultaneously.Liquid collecting tank reaches the liquid level of regulation while normally working will carry out oil extraction operation, and oil phase is entered to sump oil system.When liquid trap occurs to block, by tearing liquid level meter open, connecing the work such as sebific duct, workload is large, and the processing time is long.If oil trap cannot carry out oil extraction operation because long-time running generation sump oil blocks, can badly influence the normal operation of compressor.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the existing liquid collecting tank existing in background technique because sump oil blocks, to cause the obstructed problem that is difficult to processing of oily reclaim line, and provide a kind of diesel oil hydrogenation compressor liquid collecting tank oil draining system, this diesel oil hydrogenation compressor liquid collecting tank oil draining system, treatment effeciency is high, can make liquid collecting tank return to normal working by quick oil-discharging, guarantee compressor smooth running.
The invention for solving the technical problem can reach by following technical solution: this diesel oil hydrogenation compressor liquid collecting tank oil draining system, comprise liquid collecting tank, described liquid collecting tank middle part connects gas leakage supplied materials pipeline, and liquid collecting tank is filled with end connection oil recovery pipeline, and oil recovery pipeline connects sump oil collecting tank; Flare line is removed in the connection of liquid collecting tank abhiseca, goes flare line to connect torch tank; On described gas leakage supplied materials pipeline, be connected to gas leakage recovery valve, on oil recovery pipeline, be connected to fuel outlet valve, go to be connected to one-way valve and torch valve on flare line, the described flare line one-way valve front portion of going connects nitrogen line, is connected to one-way valve and nitrogen valve on nitrogen line.
The utility model is compared and can be had following beneficial effect with above-mentioned background technology: this diesel oil hydrogenation compressor liquid collecting tank oil draining system is owing to adopting above-mentioned flow process, when liquid trap occurs to block, only need open nitrogen valve passes into nitrogen, can fast obstructive position be processed unimpededly, can process fast, workload greatly reduces, processing time shortens, efficiency is high, makes fast liquid collecting tank return to normal working, guarantees compressor smooth running.
accompanying drawing explanation:
Accompanying drawing 1 is schematic flow sheet of the present utility model.
In figure: 1-liquid collecting tank, the 2-recovery valve that leaks gas, 3-gas leakage supplied materials pipeline, 4-nitrogen line, 5-nitrogen valve, 6-torch valve, 7-removes flare line, 8-fuel outlet valve, 9-oil recovery pipeline, 10-sump oil collecting tank, 11-torch tank.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this diesel oil hydrogenation compressor liquid collecting tank oil draining system, comprises liquid collecting tank 1, and described liquid collecting tank 1 middle part connects gas leakage supplied materials pipeline 3, and liquid collecting tank is filled with end connection oil recovery pipeline 9, and oil recovery pipeline 9 connects sump oil collecting tanks 10; Flare line 7 is removed in liquid collecting tank 1 abhiseca connection, goes flare line 7 to connect torch tanks 11; On described gas leakage supplied materials pipeline 3, be connected to gas leakage recovery valve 2, on oil recovery pipeline 9, be connected to fuel outlet valve 8, go on flare line 7 to be connected to one-way valve and torch valve 6, the described anterior nitrogen lines 4 that connect of flare line 7 one-way valves that go, are connected to one-way valve and nitrogen valve 5 on nitrogen line 4.
This diesel oil hydrogenation compressor liquid collecting tank oil draining system, when flow container occurs to block, first throttle down gas leakage recovery valve 2, torch valve 6, fuel outlet valve 8, then open nitrogen valve 5 and pass into nitrogen pressurising in liquid collecting tank, when pressure reaches 0.4-0.5MPa (G), open fuel outlet valve 8, sump oil is entered to sump oil system.
This diesel oil hydrogenation compressor liquid collecting tank oil draining system, blue stone Co., Ltd diesel hydrotreating unit in grand celebration, at the liquid trap System Implementation of compressor unit the present invention, realized in actual use nitrogen connecting system, shortened the time of processing liquid trap system jams, guaranteed the normal operation of significant element compressor assembly in diesel hydrotreating unit, practical effect is desirable.
