Abstract
The utility model discloses a system for improve small -size steam turbine circulating water quality, drainage device two, the drainage device no. 1 that includes the drainage device no. 1 who links to each other with the boiler and link to each other with the oxygen -eliminating device and drainage device no. 2 all with collect the pond and link to each other, collect the entry that passes through force (forcing) pump and cooling tower in the pond and link to each other, the export of cooling tower links to each other with steam turbine circulating water system. The beneficial effect of the utility model: the utility model discloses a cyclic utilization to the water of boiler periodical blowdown's water and oxygen -eliminating device blowdown has practiced thrift the resource on the one hand, and on the other hand because the quality of water condition of the water of above -mentioned blowdown is relatively good, has reduced the addition of circulating water medicament, has also reduced the risk of scale deposit in the condenser.
Description
Technical field
The utility model relates to circulation technical field, specifically, relates to a kind of system that improves small steam turbine recirculated water quality.
Background technology
At present, the area that has a lot of lacks of water of China, the recirculated water of these regional Method of Small Scale Turbo-generator, major part is the waste water that the salinity of river or recycling is higher, cause the cost of circulation treatment agent to increase, also the fouling of the condenser copper tubes of mode steam turbine often, has a strong impact on the efficiency of steam turbine.
As shown in Figure 1, it is all that trench 9 is directly discharged that the boiler periodical blowdown of traditional Method of Small Scale Turbo-generator and oxygen-eliminating device blowdown discharge water, not comprehensive utilization, thus cause very large waste.
Utility model content
The purpose of this utility model is to provide a kind of system that improves small steam turbine recirculated water quality, to overcome currently available technology above shortcomings.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of system that improves small steam turbine recirculated water quality, comprise the drainage arrangement one being connected with boiler and the drainage arrangement two being connected with oxygen-eliminating device, described drainage arrangement one is all connected with collection pond with drainage arrangement two, described collection pond is connected with the entrance of cooling tower by force (forcing) pump, and the outlet of described cooling tower is connected with steam turbine cycle water system.
Further, described drainage arrangement one and drainage arrangement two are drainpipe.
Further, between described boiler and collection pond, be also connected with hydrophobic development unit.
The beneficial effects of the utility model: the recycling of the water of the utility model by the water to boiler periodical blowdown and oxygen-eliminating device blowdown, save on the one hand resource, on the other hand, because the condition of water quality of the water of above-mentioned blowdown is relatively good, reduce the addition of recirculated water medicament, also reduced the risk of fouling in condenser.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural scheme of mechanism before the transformation of small steam turbine circulation;
Fig. 2 is according to the structural representation of the system of the raising small steam turbine recirculated water quality described in the utility model embodiment.
In figure:
1, boiler; 2, drainage arrangement one; 3, oxygen-eliminating device; 4, drainage arrangement two; 5, collect pond; 6, force (forcing) pump; 7, cooling tower; 8, hydrophobic development unit; 9, trench.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment. Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope that the utility model is protected.
As shown in Figure 2, according to a kind of system that improves small steam turbine recirculated water quality described in embodiment of the present utility model, comprise the drainage arrangement 1 being connected with boiler 1 and the drainage arrangement 24 being connected with oxygen-eliminating device 3, described drainage arrangement 1 is all connected with collection pond 5 with drainage arrangement 24, described collection pond 5 is connected with the entrance of cooling tower 7 by force (forcing) pump 6, and the outlet of described cooling tower 7 is connected with steam turbine cycle water system.
In the present embodiment, described drainage arrangement 1 and drainage arrangement 24 are drainpipe.
In the present embodiment, between described boiler 1 and collection pond 5, be also connected with hydrophobic development unit 8.
Operation principle of the present utility model: the utility model boiler periodical blowdown and oxygen-eliminating device blowdown drainage system, boiler periodical blowdown and oxygen-eliminating device blowdown are discharged water and collect a pond, with after force (forcing) pump pressurization, enter cooling tower entrance, after cooling tower is cooling, enter circulation, discharging water due to boiler periodical blowdown and oxygen-eliminating device blowdown is all the water that desalination is crossed, the relatively good salt content of condition of water quality is very low, filling into of these water, reduce the rate of water make-up of recirculated water, improve the quality of recirculated water, reduce the addition of recirculated water medicament, also reduced the risk of fouling in condenser.
Effect of the present utility model: the former design cycle water of small steam turbine chemical feeding quantity is larger, condenser scale removal half a year once. After transformation, recirculated water chemical feeding quantity has reduced 10% than originally. Condenser operation half a year, the undiminished phenomenon of steam turbine vacuum, has effectively stablized the efficiency of steam turbine, saves every year medicament fund and 70,000 yuan of funds of condenser cleaning are whole, has guaranteed the stable of the safety and stability of generating equipment operation and efficiency.
In sum, by means of technique scheme of the present utility model, recycling of the water of the utility model by the water to boiler periodical blowdown and oxygen-eliminating device blowdown, save on the one hand resource, on the other hand, because the condition of water quality of the water of above-mentioned blowdown is relatively good, reduce the addition of recirculated water medicament, also reduce the risk of fouling in condenser.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
