Preferably, the first valve is provided with between described removal bitter and fishiness and stand-by plant high-temperature hot water pot, liquid-phase outlet bottom described water wash column and be provided with the second threeway between the recycle pump of Heisui River, liquid-phase outlet bottom described water wash column and be provided with the second valve between the second threeway, 3rd end of the second threeway is provided with liquid showering guilding valve under water wash column, between described Heisui River recycle pump and the 3rd end of the first threeway, is provided with the 3rd valve.
The utility model has simple to operate, invests minimum, switches easily and the advantage favourable to the long-term operation of device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described, label identical in the various figures represents identical parts.For making simplified form, only schematically show the part relevant to utility model in each figure, they do not represent its practical structures as product.
As shown in Figure 1, the utility model comprises heat reclamation device 12, heat reclamation device 12 by pipeline successively with sealing water-to-water heat exchanger 13, the 4th valve 14 with seal that supply mains 15 is connected, the described supply mains of sealing 15 seals water user with several and is connected, the 3rd end being provided with the first threeway 10, first threeway 10 between described 4th valve 14 and sealing supply mains 15 is connected with stand-by plant; Described stand-by plant comprises removal bitter and fishiness 1, removal bitter and fishiness 1 is connected with water wash column 6 with stand-by plant high-temperature hot water pot 4, high temperature hot water pump 5 successively by pipeline, and the liquid-phase outlet bottom described water wash column 6 is connected with the 3rd end of the first threeway 10 with Heisui River recycle pump 7 by pipeline.The first valve 2 is provided with between described removal bitter and fishiness 1 and stand-by plant high-temperature hot water pot 4, liquid-phase outlet bottom described water wash column 6 and be provided with the second threeway 11 between Heisui River recycle pump 7, liquid-phase outlet bottom described water wash column 6 and be provided with the second valve 3 between the second threeway 11,3rd end of the second threeway 11 is provided with liquid showering guilding valve 8 under water wash column, between described Heisui River recycle pump 7 and the 3rd end of the first threeway 10, is provided with the 3rd valve 9.
When the close sealing water device of coal water slurry gasification normally runs, close the first valve 2, second valve 3 and the 3rd valve 9, the heat seal water of now coming in heat reclamation device 12 forms cold sealing water after carrying out heat exchange cooling by sealing water-to-water heat exchanger 13, described cold sealing water enters in sealing supply mains 15 by the 4th valve 14, is transported in several sealing water users by sealing supply mains 15 by sealing water; When sealing water-to-water heat exchanger 13 and breaking down, close the 4th valve 14, repair and maintenance is carried out to sealing water-to-water heat exchanger 13, while repair and maintenance is carried out to sealing water-to-water heat exchanger 13, open the first valve 2, second valve 3 and the 3rd valve 9; The de-salted water of coming in removal bitter and fishiness 1 enters stand-by plant high-temperature hot water pot 4 by pipeline, enter in water wash column 6 after being pressurizeed by high temperature hot water pump 5 by the de-salted water of stand-by plant high-temperature hot water pot 4, enter in the first threeway 10 by the liquid-phase outlet bottom water wash column 6 and Heisui River recycle pump 7, finally be transported in several sealing water users, for sealing water user by sealing supply mains 15.
