Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, Nuclear Power Station refuse factory building provided by the present invention energy-conservation safeguards system of annual refrigeration duty for technique, comprise the cooling tower 1 and the water-cooled handpiece Water Chilling Units 4 that by cooling water house steward 2, cooling water return main 3, are connected, described water-cooled handpiece Water Chilling Units 4 is connected with aqueous waste drier 10 with chilled water return main 6 by chilled water water main 5, on described cooling water house steward 2 and chilled water return main 6, is connected with respectively level pressure equipment.Described cooling tower 1 is closed cooling tower, and closed cooling tower (being also evaporating air cooler or closed cooling tower) is that pipe heat exchanger is placed in tower, the heat exchange assurance cooling-down effect of air, shower water and recirculated water by circulation.Between cooling water house steward 2 and cooling water return main 3, be provided with flow control valve V6.On described cooling water house steward 2, be provided with the frequency conversion of cooling water pump 7(band), on described chilled water return main 6, be provided with the frequency conversion of chilled water pump 8(band).Adopt closed cooling tower, the antifreeze of cooling tower winter can be by bleeding off the water of water leg and completing according to the regular low cruise cooling water pump 7 of outdoor temperature at severe cold season.
Described cooling water house steward 2 is connected with chilled water water return pipeline 12 with the chilled water supply channel 11 that is connected Hydraulic Station 9 respectively, on described chilled water supply channel 11 and chilled water water return pipeline 12, is respectively equipped with valve V4, V5.The chilled water supply channel 11 that connects Hydraulic Station 9 is connected with the chilled water water main 5 who is located between water-cooled handpiece Water Chilling Units 4 and aqueous waste drier 10, is provided with valve V1 on connected pipeline; The chilled water water return pipeline 12 that connects Hydraulic Station 9 is connected with the chilled water return main 6 who is located between water-cooled handpiece Water Chilling Units 4 and aqueous waste drier 10, is provided with valve V2 on connected pipeline.In the winter time; cooling tower supplies water and first after the hydraulic press intensification of Hydraulic Station 9, enters refrigeration machine again; avoided because cooling tower supply water temperature is lower, the regulating power of cooling sea water regulating valve is limited and cause the fault that handpiece Water Chilling Units is shut down, and then affects the problem of the normal work of process equipment.
In summer, the chilled water system operation routinely of this system, the flow that changes cooling water by temperature control valve (TCV) at transition season makes handpiece Water Chilling Units that chilled water is normally provided; In the winter time, by closed cooling tower for hydraulic press is simultaneously also for water-cooled handpiece Water Chilling Units provides cooling water; Handpiece Water Chilling Units is that the process equipment (aqueous waste drying equipment) of demand refrigeration duty provides chilled water, met so simultaneously technique in the winter time use cold demand, make again refrigeration system normally operation in the winter time, whole system is also in energy-saving run state simultaneously.
Below in conjunction with accompanying drawing 1, Nuclear Power Station refuse factory building technique is described in the operational mode of Various Seasonal by the energy-conservation safeguards system of annual refrigeration duty.
In summer, valve V1, V2, V3 open; V4, V5, V6 close, and system is that a conventional freezing water system is that two users (the aqueous waste drier of the hydraulic press of Hydraulic Station, refuse drying room) provide chilled water.
At transition season, valve V1, V2, V3 open; V4, V5 close, and V6 opens during lower than 25 ℃ at cooling water temperature, and start to regulate and enter the cooling tower water yield.System is a conventional freezing water system, but cooling water flow regulates by motor-driven valve, and assurance system is normally moved.
In the winter time, valve V1, V2, V3 close; V4, V5 open, and V6 opens and regulates cooling water flow.The hydraulic press that is Hydraulic Station by closed cooling tower (high temperature user) and water-cooled handpiece Water Chilling Units provide cooling water; Water-cooled handpiece Water Chilling Units is that the aqueous waste drier (low temperature user) of refuse drying room provides chilled water.Cooling tower, water-cooled handpiece Water Chilling Units can independent operatings.
Operational mode refers to following table:
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if of the present invention these are revised and within modification belongs to the scope of the claims in the present invention and equivalent technology thereof, the present invention is also intended to comprise these changes and modification interior.
