When coal fired generator set desulfurization industry water used is opened water, will there is potential safety hazard in main factory industry water desulphurization plant of having no progeny, stop number of times by non-for increase.Because power plant's industry water uses river surface water, after precipitation, deliver to steam power plant as uses such as chemical demineralizing water, fire water, steam turbine open and close type water, subsidiary engine cooling water, desulfurization industry waters by water pump through raw water pipeline.Existing water treatment facilities there will be industry water discontinuity events, simultaneously because present industrial water tank only has 50m
3left and right, lower of full load situation is desulphurization plant cooling water, machine water shutoff 1 hour consumption enough, and industry water interrupt event causes desulfurization industrial water tank liquid level to be down to below industrial water pump entrance, runs bring very large potential safety hazard to desulphurization plant.
When industry water is opened water, because desulfurization industry water uses mainly as subsidiary engine cooling water and machine water shutoff, finally all enter in absorption tower as the moisturizing on absorption tower, do not recycle, so industry water consumption is large, and 4.68 yuan per ton, project management department's production cost improves, and cannot meet requirement that is energy-saving and cost-reducing, economical operation.
Summary of the invention
For solving the problem, the object of the present invention is to provide one effectively to avoid unit fault to occur, and make desulfurization fume reach the closed cycle water device of environment protection emission requirement.
The invention provides a kind of closed cycle water device, comprising:
First industrial water tank, it is separated by dividing plate and technique water tank;
Second industrial water tank, it is connected with described first industrial water tank by industrial jellyfish Guan mono-road arm, described second industrial water tank arranges an apopore, described apopore causes described first industrial water pump and described second industry water pump intake piping place by carbon steel pipe, and described first industrial water pump is connected with described second industrial water tank by carbon steel pipe with described second industrial water pump;
Commercial recovery water tank, it is connected with the first commercial recovery water pump and the second commercial recovery water pump by stainless steel tube, and described first commercial recovery water pump is connected with described second industrial water tank and described technique water tank by stainless steel tube with described second commercial recovery water pump.
Further improve as the present invention, described apopore is positioned at described second industrial water tank height 0.5m place.
Further improve as the present invention, the diameter of described apopore is 80mm.
Further improve as the present invention, the diameter of described carbon steel pipe is 80mm.
Further improve as the present invention, described first industrial water tank is of a size of 7.5m × 4.5m × 3.0m.
Further improve as the present invention, described second industrial water tank is of a size of 3.5m × 4m × 4m.
Further improve as the present invention, described commercial recovery water tank is of a size of 3m × 4m × 3m.
Further improve as the present invention, the flow of described first commercial recovery water pump and described second commercial recovery water pump is 30m3/h, and lift is 30m.
Further improve as the present invention, described stainless steel tube is snake bend.
Beneficial effect of the present invention is: the stable operation that ensure that power plant's main frame, desulphurization system stable operation, efficiently avoid the generation of unit fault, desulfurization fume reaches the requirement of environment protection emission, and after carrying out the transformation of industry water enclosed, the industrial water yield reduces, the increase of the technique water yield can larger minimizing production cost, annual about minimizing 600,000 yuan, optimizes design and reduces cost, have great economic implications.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of closed cycle water device described in the embodiment of the present invention.
In figure: 1, the first industrial water tank; 2, technique water tank; 3, the second industrial water tank; 4, industry water return water tank; 51, the first industrial water pump; 52, the second industrial water pump; 61, the first commercial recovery water pump; 62, the second commercial recovery water pump.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Embodiment 1, as shown in Figure 1, a kind of closed cycle water device described in the embodiment of the present invention, comprises two industrial water tanks, a technique water tank and a commercial recovery water tank.First industrial water tank 1 is separated by dividing plate and technique water tank 2, first industrial water tank 1 is connected with the second industrial water tank 3 by industrial jellyfish Guan mono-road arm, the industry that main factory comes is injected in the second industrial water tank 3, high 0.5 meter of of second industrial water tank 3 arranges the apopore that a diameter is 80mm, apopore is connected with the first industrial water pump 51 and the second industrial water pump 52 by the carbon steel pipe of diameter 80mm, realize industry water two-way to supply water, the first industrial water pump 51 is connected with the second industrial water tank 3 with the carbon steel pipe of the second industrial water pump 52 by diameter 80mm.Commercial recovery water tank 4 is connected with the first commercial recovery water pump 61 and the second commercial recovery water pump 62 by stainless steel snake bend, all industry water backwater are all drawn in access industrial Water Sproading water tank 4, first commercial recovery water pump 61 is connected with the second industrial water tank 3 by stainless steel snake bend with the second commercial recovery water pump 62, squeezes in the second industrial water tank 3 after being cooled by industry water recycle-water.
