Abstract
The utility model provides an energy-saving water supply and drainage system, and relates to the technical field of water supply and drainage system design. The energy-saving water supply and drainage system comprises a circulating water pool, a cooling tower, multiple sets of heat exchanger units and a circulating pipeline. Water cooled through the cooling tower flows into the circulating water pool through the circulating pipeline, the circulating pipeline comprises a water supply header pipe and a water return header pipe, the heat exchanger units are connected between the water supply header pipe and the water return header pipe in parallel through connecting pipelines respectively, a circulating water pump is correspondingly arranged on the connecting pipeline between each heat exchanger unit and the water supply header pipe, a first control valve is arranged on the connecting pipeline between each circulating water pump and the water supply header pipe, and a second control valve is arranged on the connecting pipeline between each heat exchanger unit and the water return header pipe. Compared with a traditional mode that water is supplied to multiple heat exchangers through a single water supply system, the energy-saving water supply and drainage system is lower in the total energy consumption and has a good energy-saving effect.
Description
Technical field
The utility model relates to the design field of supply and drain water system.
Background technology
Existing supply and drain water system adopts multiple pump groups to supply water in a system in the time that heat exchanger filling pipe end supplies water, and owing to having selected the pump that lift is identical, and heat exchanger distribution distance is not etc., has therefore caused pump to depart from inefficient operating point operation, causes the waste of the energy.
Utility model content
The utility model object is for above problem, and a kind of energy-saving supply and drain water system is provided.
The utility model comprises circulating water pool, cooling tower, multi-group heat exchanger unit, circulation line, and the water cooling through cooling tower enters circulating water pool by circulation line; Described circulation line comprises supply mains and return main, described multi-group heat exchanger unit is connected in parallel between upper supply mains and return main by connecting pipe respectively, in the connecting pipe between each described heat exchanger unit and upper supply mains, corresponding water circulating pump is set respectively, first control valve is set respectively in the connecting pipe between described each water circulating pump and upper supply mains; Second control valve is set respectively in the connecting pipe between each heat exchanger unit and return main.
The utility model adopts multiple water circulating pumps to supply water to multi-group heat exchanger, and heat exchange Hou You mono-road pipeline enters cooling tower and pond; Due to the difference of heat exchanger far and near distance, the pump lift difference in the choice of corresponding every group of heat exchanger unit, power of motor is also different, can make so every group of pump all respectively in the operation of efficient district, the mode that the traditional single water system of overall energy consuming ratio supplies water to multiple heat exchangers is low, has good energy-saving effect.
The each described heat exchanger unit of the utility model comprises respectively the heat exchanger of multiple parallel connections.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises circulating water pool 1, cooling tower 2, First Heat Exchanger unit 3-1, the second heat exchanger unit 3-2, the 3rd heat exchanger unit 3-3, circulation line 4, the water cooling through cooling tower 2 enters circulating water pool 1 by circulation line 4, and First Heat Exchanger unit 3-1, the second heat exchanger unit 3-2, the 3rd heat exchanger unit 3-3 comprise respectively the heat exchanger 3 of multiple parallel connections.
In the connecting pipe 5 of 4-1 between First Heat Exchanger unit 3-1 and upper supply mains, the first water circulating pump 6 is set, in the connecting pipe 5 between the second heat exchanger unit 3-2 and upper supply mains 4-1, the second water circulating pump 7 is set, in the connecting pipe 5 between the 3rd heat exchanger unit 3-3 and upper supply mains 4-1, the 3rd water circulating pump 8 is set; The lift of the first water circulating pump 6, the second water circulating pump 7 and the 3rd water circulating pump 8 is corresponding with heat exchanger unit distribution distance respectively.
In the connecting pipe 5 between the first water circulating pump 6, the second water circulating pump 7 and the 3rd water circulating pump 8 and upper supply mains, the first control valve 9 is set respectively; In the connecting pipe 5 between First Heat Exchanger unit 3-1, the second heat exchanger unit 3-2, the 3rd heat exchanger unit 3-3 and return main 4-2, the second control valve 10 is set respectively.
