Description
Technical field：The present invention relates to industrially desulfurized field, especially a kind of backwash poor liquid filter of desulfurization.
Background technology：
Because desulphurization system amine liquid carrying coke powder is more, although conventional lean liquid filter can filter coke powder therein, because of mistake
Filter needs frequent disassembly, cleaning, changes filter cloth and seal, not only cost it is high and during disassembly, cleaning caused peculiar smell and useless
Slag can pollute surrounding environment.Because coking dry gas and liquefied gas contain a large amount of coke powders, after being mixed into desulphurization system with amine liquid, its
In a large amount of coke powders carried after the washing of amine liquid by amine liquid into regenerative system, easily cause desulfurization regeneration system jams tower tray, damage
Bad machine, which seals, has a strong impact on the long-term operation of device, and a large amount of coke powders exist and the foaming of amine liquid is easily caused in amine liquid has a strong impact on desulfurization
Effect, desulfurized effect need to be kept by frequently filling or changing fresh amine liquid, further increase the cost of device.Part
Technique is using installation bag type filter, so as to impurity contents such as coke powders in reduction system, but because in amine liquid impurity it is more, mistake
Filter cleans and filter bag replacing is excessively frequent, not only increases the workload of operative employee, certain journey is even more caused to surrounding environment
The pollution of degree.
The content of the invention：The object of the invention provides a kind of backwash poor liquid filter of desulfurization.
The present invention is realized by following technological means：One kind backwash the poor liquid filter of desulfurization, by poor flow container with
Filter inlet, outlet and connecting pipeline valve composition, filter are provided with flushing water access pipeline, flushing water access pipeline
It is connected and extends at the top of filter interior screen cloth with flushing water pot by pump valve structure, filter is provided with nitrogen access tube
Line, nitrogen access pipeline are connected by pump valve structure with nitrogen storage tank, and filter interior sets screen cloth, and the screen bottom is set
There are pressure gauge, filter bottom to lead shower pipe line, lead shower pipe line and be connected by pump valve structure with poor flow container, filter bottom is provided with
The waste line and pump valve structure that are connected with wastewater disposal basin, filter interior are provided with spray on the clean-up line at the top of screen cloth
Hole.Beneficial effect of the present invention：While avoiding ambient contamination, plant operations work cleaning filter and is more more reduction of
Change the workload and production cost of filter bag
Brief description of the drawings：Fig. 1 is schematic structural view of the invention
Poor flow container 1, filter 2, rinse water pot 3, nitrogen storage tank 4, screen cloth 5, pressure gauge 6, lead shower pipe line 7, wastewater disposal basin 8,
Spray apertures 9
Embodiment
As shown in figure 1, a kind of backwash poor liquid filter of desulfurization, by poor flow container 1 and the entrance of filter 2, outlet and company
Adapter line valve composition, filter 2 are provided with flushing water access pipeline, and flushing water access pipeline passes through pump valve structure and flushing water
Tank 3 connects and extends to the top of 3 internal screen of filter 5, and filter 3 is provided with nitrogen access pipeline, and nitrogen access pipeline leads to
Cross pump valve structure to be connected with nitrogen storage tank 4, the inside of filter 3 sets screen cloth 5, and the front end of screen cloth 5 is provided with pressure gauge 6, mistake
The bottom of filter 3 leads shower pipe line 7, leads shower pipe line 7 is connected by pump valve structure with poor flow container 1, and the bottom of filter 3 is provided with and waste water
Spray apertures 9 are provided with the clean-up line at the top of screen cloth 5 inside the waste line and pump valve structure, filter 3 that pond 8 connects,
Further improved on the basis of conventional filter bag formula filter, filter bag is changed to special stainless steel screen cloth 5, the pressure 6 before screen cloth 5
After reaching to a certain degree, the inlet valve of filter 3 is closed, it is using nitrogen to the pressurising of filter 3, the inside points cleaning of filter 3 is poor
Liquid delivers to poor flow container 1, using bottom lead shower pipe line 7 further recovery remaining part lean solution after, open bottom waste line and
Valve on backwashing water pipeline, it is rinsed and replaces using the pressure of fresh water, coke powder that screen cloth 5 is filtered down etc. is miscellaneous
Matter is drained into the wastewater disposal basin 8 in coking workshop.
