Detailed description of the invention
As shown in Figure 2, this full factory shares open cycle cooling water system, comprises supply-water pump group system 300, and the water supply be connected with the outlet of supply-water pump group system 300 distributes common header system 400, the recirculation regulating system 500 be connected with supply-water pump group system 300.
Described supply-water pump group system 300 comprises the manual filter screen 303 of 302, two, an electronic rotation filter screen 301, two open cycle cooling water pumps outlet.The entrance of wherein said electronic rotation filter screen 301 connects circulating pump room water; The outlet bifurcation road of electronic rotation filter screen 301 connects the entrance of two open cycle cooling water pumps 302 respectively, and (what the connection at this place referred to is not direct connection, but by being connected to the entrance of open cycle cooling water pump after miscellaneous part, be then prior art as miscellaneous part, therefore no longer describe in detail), each open cycle cooling water pump 302 exports and connects the manual filter screen 303 of an outlet respectively; The outlet that a road forms supply-water pump group system 300 is merged into again after the outlet of two manual filter screens 303 of outlet.
Described water supply distributes common header system 400 and comprises two groups of water systems, two groups of water systems are in parallel, often organize on the main line in water system and be disposed with check-valves 401, control valve 402, isolating valve 403, flow meters 405 according to water (flow) direction, the outlet of the flowmeter 405 of one group of water system is connected to No. 1 machine user, and the outlet of the flowmeter of another group water system is connected to No. 2 machine users.
This full factory shares in open cycle cooling water system, often organize water system and one bypass is also set, bypass is arranged a bypass valve 404, the entrance of bypass valve 404 is in parallel with the entrance of check-valves 401 is a place, and the outlet of bypass valve 404 is in parallel with the outlet of isolating valve 403 is a place.
Described recirculation regulating system 500 comprises two isolating valves 501,503 be connected on same pipeline, a recirculation control valve 502.Two isolating valves 501,503 lay respectively at the both sides of described recirculation control valve 502, and the entrance of an isolating valve 501 connects the outlet of supply-water pump group system 300, and the outlet of another isolating valve 503 is connected to circulating pump room.
At the unit starting initial stage, recycle the safety that regulating system 500 is used for protecting cooling water pump, prevent pump group from producing cavitation.In operation, when a compressor emergency shutdown, owing to not needing cooling water, by opening recirculation control valve 502, adjusting pump group water supply flow, maintaining system running pressure and stablizing, realizing total system stable operation.Usual recirculation regulating system regulating pondage scope of design is between 30 ~ 60%.
" connection " in the utility model existing direct connection, also has the indirect connection after miscellaneous part, can directly find out from Fig. 2, and therefore in this unified explanation, what " connection " in the utility model can not be narrow is interpreted as direct connection.For situation about indirectly connecting, the miscellaneous part due to centre is prior art, and also can not affect fully open even if therefore do not elaborate, this is all in this area known by those skilled in the art.
During work, recirculated cooling water first filters the large granular impurity at intake place through electronic rotation filter screen 301, then boost through open cycle cooling water pump 302, and two open cycle cooling water pumps one are transported one standby.Again after exporting manual filter screen 303 and filtering minute impurities, be divided into two benches.
First stage; when the initial start-up of supply-water pump group or wherein a unit is stopped using time; supply water and first flow through recirculation regulating system; recirculation control valve 502 is opened, and is used for protecting, regulating supply-water pump group safety, maintains system pressure and stablizes; when the flow by recycling control valve 502 is greater than 50%; the distribution common header system 400 that then supplies water is opened, and open type supplies water to user, enters second stage.
In second stage, when supply-water pump group system flow is greater than 50%, supply water and distribute the check-valves 401 of common header system 400, control valve 402, isolating valve 403 is all opened, then supplying water is delivered to each user.When in operation, when occurring that a certain user stops not needing cooling water, then flowmeter 405 records discharge reduction, and transmission of signal, to control room, reduces aperture to control to adjust valve 402 adjustment, reduces chilled(cooling) water supply (CWS) amount, realize the Appropriate application of water resource.Vice versa, according to actual conditions distribution according to need water consumption, reaches water-saving object.When control valve 402 fault, can emergency opening bypass valve 404, guarantee that system water supply is safe and reliable, realize not shutting down on-bne repair.
