Background technology
Current, in use Sweet natural gas, petroleum gas or coal generating gas carry out the process of industrial synthetic coarse methanol, no matter be domestic methanol technics or external methanol synthesizing process, the high carbon chain hydrocarbon polymer and the paraffinic hydrocarbon (being referred to as paraffin) that all find that there is in various degree generate.And existing methanol synthesizer does not all arrange separately paraffin removal equipment, for the assurance device long-term operation, existing paraffin removal process takes to boil online wax more, rely on synthesis gas directly wax to be heated, after making to be attached to the paraffin thawing of equipment inner wall, be sent to thick methyl alcohol storage tank with methanol liquid, then be sent to methanol rectifying system by fresh feed pump, yet there will be so again a large amount of paraffin to be attached on the filter screen of fresh feed pump entrance, by the mode of clearing up filter screen, paraffin is cleared out to system.
Because filter capacity is limited, and the cleaning filter screen need be isolated strainer, for guaranteeing that rectifier unit moves continuously, two strainer parallel runnings are set, but at catalyst for methanol, use later stage paraffin to generate when more, still have the serious latch up phenomenon of strainer, because the paraffin accumulation is too fast, the repair time that there is no enough dismounting and cleaning filter screens, cause methanol rectifying system to be forced to the situation of stopping.The mode that paraffin is cleared out to system by the cleaning filter screen needs frequent dismounting filter screen, greatly increases maintenance workload, and particularly, for the high pressure filter of system for methanol synthesis, dismounting and cleaning primary filter screen required time is longer, and the long-term maintenance spare parts in a large number that consume.
The utility model content
The purpose of this utility model is to provide a kind of de-waxing apparatus of methanol production system, has solved the problem that in existing methanol production system production process, thick methyl alcohol strainer is easily stopped up by paraffin.
The technical scheme that the utility model adopts is: the de-waxing apparatus of methanol production system, comprise thick methyl alcohol strainer, slightly the methyl alcohol strainer advances methanol line and goes out on methanol line to be respectively equipped with into stopping valve and go out stopping valve, the bottom of thick methyl alcohol strainer connects the de-waxing pipeline, the de-waxing pipeline is provided with the de-waxing valve, and the top of thick methyl alcohol strainer connects vent line, and vent line is provided with vent valve, vent line is flexibly connected the low-pressure steam pipeline, and the low-pressure steam pipeline is provided with steam valve.
Characteristics of the present utility model also are,
Between vent line and low-pressure steam pipeline, adopt flange to be flexibly connected.
The bottom of thick methyl alcohol strainer connects blowdown pipeline, and blowdown pipeline is provided with wash water valve.
Be provided with and lead the pouring pipeline in the front of steam valve on the low-pressure steam pipeline, lead the pouring pipeline and be provided with showering guilding valve.
Be provided with the paraffin receiving tank below the outlet of de-waxing pipeline.
The beneficial effects of the utility model are: the characteristics that the de-waxing apparatus of the utility model methanol production system can hot melt according to paraffin, adopt low-pressure steam to pass into the strainer vent line, after directly paraffin being melted, drain into the paraffin receiving tank with steam from filter bottom de-waxing pipeline, do not need the dismounting filter screen, consuming time short, simple to operate, easy to maintenance, reduced workload and cost, improved working efficiency.
The accompanying drawing explanation
Fig. 1 is the structural representation of the de-waxing apparatus of the utility model methanol production system.
In figure, 1. thick methyl alcohol strainer, 2. advance methanol line, 3. advance stopping valve, 4. vent valve, 5. vent line, 6. flange, 7. steam valve, 8. low-pressure steam pipeline, 9. lead the pouring pipeline, 10. showering guilding valve, 11. go out methanol line, 12. go out stopping valve, 13. wash water valves, 14. blowdown pipelines, 15. the paraffin receiving tank, 16. de-waxing valves, 17. de-waxing pipelines.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of de-waxing apparatus of methanol production system, as shown in Figure 1, comprise thick methyl alcohol strainer 1, slightly methyl alcohol strainer 1 advances methanol line 2 and goes out on methanol line 11 to be respectively equipped with into stopping valve 3 and go out stopping valve 12, the bottom of thick methyl alcohol strainer 1 connects de-waxing pipeline 17, de-waxing pipeline 17 is provided with de-waxing valve 16, the top of thick methyl alcohol strainer 1 connects vent line 5, vent line 5 is provided with vent valve 4, vent line 5 is flexibly connected low-pressure steam pipeline 8, and low-pressure steam pipeline 8 is provided with steam valve 7.Between vent line 5 and low-pressure steam pipeline 8, adopt flange 6 to be flexibly connected.The bottom of thick methyl alcohol strainer 1 connects blowdown pipeline 14, and blowdown pipeline 14 is provided with wash water valve 13.Be provided with in the front of steam valve 7 on low-pressure steam pipeline 8 to lead and drench pipeline 9, lead pouring pipeline 9 and be provided with showering guilding valve 10.Be provided with paraffin receiving tank 15 below the outlet of de-waxing pipeline 17.
When needs are cleared up the paraffin of thick methyl alcohol strainer 1 filter screen, at first stopping valve 3 is advanced on methanol line 2 in advancing of thick methyl alcohol strainer 1, and the stopping valve 12 that goes out gone out on methanol line 11 is closed, open the wash water valve 13 on vent valve 4 on thick methyl alcohol strainer 1 top vent line 5 and thick methyl alcohol strainer 1 bottom blow-down pipeline 14 simultaneously, in thick methyl alcohol strainer 1, residual methyl alcohol will be drained in underground methyl alcohol receiving tank by underground blowdown pipeline 14, until discharge again without methyl alcohol, thick methyl alcohol strainer 1 noresidue methyl alcohol is described.Close subsequently wash water valve 13, and open the de-waxing valve 16 on de-waxing pipeline 17, discharge residual methanol in de-waxing pipeline 17.Open again and lead the showering guilding valve 10 drenched on pipeline 9, after having steam to discharge, showering guilding valve 10 is closed.Then vent line 5 and low-pressure steam pipeline 8 use flanges 6 are flexibly connected, slowly open the steam valve 7 on low-pressure steam pipeline 8.Because paraffin has the advantages that easily melted by heat, so after low-pressure steam enters thick methyl alcohol strainer 1, paraffin can be melted, and enters paraffin receiving tank 15 with steam from the de-waxing pipeline 17 of thick methyl alcohol strainer 1 bottom, until paraffin melts fully and discharges.Last steam off valve 7, disconnect flange 6, closes de-waxing valve 16 and vent valve 4.
So thick methyl alcohol strainer 1 just completes paraffin removal, can again come into operation.Whole process does not need the dismounting filter screen, consuming time short, simple to operate, and easy to maintenance.
