Abstract
The invention discloses a water supply system for a demister flushing device. The water supply system comprises a flushing water tube (1), a flushing water tank (2), a flushing water pump (3), a pipeline (4), a water storage tank (5) and valves (7, 8, 9), wherein the flushing water tube (1) is connected with the flushing water tank (2); the flushing water tank (2) is connected with the flushing water pump (3); the flushing water pump (3) is connected with the water storage tank (5); and the flushing water tank (2) is higher than the flushing water tube (1). When the system operates, an original system pipeline valve which shares the flushing water pump (3) with the water supply system is closed, the valves (7) and (8) are opened, the valve (9) is closed, and the flushing water pump (3) is utilized to add water into the flushing water tank (2); when a demister (6) is required to flush, the valves (7) and (8) are closed, the valve (9) is opened, and the demister (6) is flushed by virtue of pressure difference generated by different heights of the flushing water tank (2) and the flushing water tube (1). The water supply system is simple, and an independent water pump is not required, so that investment and operation cost of a desulfurization system can be reduced.
Description
Technical field
The invention belongs to flue gas desulfurization mist eliminator flushing technical field, particularly relate to a kind of water system of mist eliminator flushing device.
Background technology
Technology for Domestic Flue Gas Desulfurization capital equipment is fume desulfurizing tower, and its inside is provided with demist layer, for removing the mist-like drop carried in flue gas, causes new pollution after preventing purifying smoke from discharging to air.Demist layer generally comprises demister body and mist eliminator flushing device.A large amount of dust can be brought into due to desulfurization fume and generate a large amount of aerosol form particle, causing demister surface accumulation dust and dirt, do not process for a long time and can have a strong impact on demisting efficiency, so all with flusher in demister use procedure.Current domestic main flow mist eliminator flushing device, is all equipped with independently water pump and trafficking pathways.But well-known, mist eliminator flushing generally adopts intermittent work, and its working time is short, and outfit water pump and pipeline reality can increase construction investment cost and operating cost separately.
Summary of the invention
For the problems referred to above, the invention provides a kind of water system of mist eliminator flushing device.
Technical scheme of the present invention is: a kind of water system of mist eliminator flushing device, includes wash tub pipe, flush box, flush water pump, pipeline, water tank and valve; Described wash tub pipe is distributed with flushing hole, forms flushing water spray; Described flush box position higher than wash tub pipe height, and is connected with wash tub pipe, flush water pump respectively through pipeline; Described flush water pump is connected with water tank further, for flush box supplies water; This water system above-mentioned and other system share a set of flush water pump; In addition, the valve of described water system is arranged in water tank and flush water pump connecting pipe respectively, in flush water pump and flush box connecting pipe and in flush box and wash tub pipe connecting pipe.In addition, the original system pipeline sharing this flush water pump with described water system is provided with valve, is installed on flush water pump respectively and exports on the original system pipeline that is connected with entrance.
This water system is run can be in two stages.
The first, flush box adds water.Namely when the original system at flush water pump place is stopped transport, close original system pipeline valve, open the valve being positioned in water tank and flush water pump connecting pipe and in flush water pump and flush box connecting pipe, flushing water is pumped into flush box by flush water pump in water tank, make the water yield in flush box reach rinsing requirement, flushing water valve can be closed.
The second, mist eliminator flushing.When demister in desulfurizing tower needs to rinse, open the valve in flush box and wash tub pipe connecting pipe, wash tub pipe flushing hole is sprayed water, and realizes mist eliminator flushing.
This water system, structure is simple, without the need to being equipped with independently flush water pump, cost of reducing investment outlay.In addition, for existing mounted mist eliminator flushing water system, by increasing the simple modifications of pipeline and valve, removing independent water pump and using, being used in the technique of high utilization rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of mist eliminator flushing device water system of the present invention.
Detailed description of the invention
In order to more clearly explain the present invention, describe in detail especially exemplified by an example, but right required by the present invention is not only in this.
A kind of mist eliminator flushing device water system as shown in Figure 1, it comprises wash tub pipe (1), flush box (2), flush water pump (3), pipeline (4), water tank (5) and valve (7,8,9); Wherein wash tub pipe (1) is distributed with flushing hole, spray irrigation is carried out to demister (6); Flush box (2) is placed higher than wash tub pipe (1), and it is connected with wash tub pipe (1), flush water pump (3), for temporary reservoir flushing water respectively by pipeline (4); Flush water pump (3) is connected with water tank (5) further, for flush box (2) supplies water; This water system is equipped with three flushing water valves (7,8,9), and it is arranged between water tank (5) and flush water pump (3) respectively, between flush water pump (3) and flush box (2) and between flush box (2) and wash tub pipe (1); In addition, this flush water pump (3) simultaneously by flue gas ammonia method desulfurizing absorption tower for ammonia system, connect ammonia water tank (12) and absorption tower slurry pool (13), valve (10,11) is provided with between flush water pump (3) and ammonia water tank (12) and between flush water pump (3) and absorption tower slurry pool (13).Wet ammonia process desulfurizing technology is intermittent operation for ammonia system, and mist eliminator flushing water system is also intermittent operation simultaneously, and two systems can coordinate interval to use flush water pump (3).
When this flue gas ammonia method desulfurizing runs for ammonia system, valve (7), valve (8) and valve (9) are closed, and valve (10) and valve (11) are opened, and ammoniacal liquor in ammonia water tank (12) is added absorption tower slurry pool (13) by flush water pump (3); When closing for ammonia system, when demister water system is opened, valve (10) and valve (11) are closed, valve (9) keeps closing, valve (7) and valve (8) are opened, flushing water in water tank (5) is pumped into flush box (2), until the suitable valve-off of water level (7) and valve (8) by flush water pump (3); When demister (6) need rinse, valve (7) and valve (8) keep closing, open valve (9), the water of the pressure official post flush box (2) produced because flush box (2) is highly different from wash tub pipe (1) enters wash tub pipe (1), carries out demister (6) and rinses.Repeat above operation to repeat to rinse to demister (6).
Claims (1)
1. a water system for mist eliminator flushing device, is characterized in that: comprise wash tub pipe (1), flush box (2), flush water pump (3), pipeline (4), water tank (5) and valve (7,8,9); Described flush box (2) position higher than wash tub pipe (1), and is connected with wash tub pipe (1), flush water pump (3); Described flush water pump (3) is connected with water tank (5).
