Description
Technical field
The utility model relates to a kind of electricity and drives compressor station water chiller closed circuit cooling system.
Background technology
In Long-distance Transmission Pipeline field, electricity drives the needs of compressor station because of natural gas transmission technique, need arrange gas compressor set and carry out supercharging.And the supporting variable-frequency motor of compressor bank and frequency converter can produce a large amount of heats in unit pressurization, for taking away this part heat in time, ensureing unit safety operation, needing in Practical Project for a set of cooling system of its design configurations.At present the most generally, the most conventional way is the recirculating cooling water system adopting open cycle cooling water system or closed cooling tower.But practical experience for many years proves that these two kinds of systems all exist many drawbacks.The disadvantages such as open cycle cooling water system exists scaling, bacterium algae grows, water resource waste, maintenance management difficulty, system complex, bring inconvenience to operational management; And the often spalling because the cooling water in coil pipe freezes when winter, compressor bank was stopped transport of the cooling coil of the recirculating cooling water system of closed cooling tower; PVC filler easy fouling under summer high temperature weather in cooling coil outer surface and tower body, causes cooling tower cooling effectiveness greatly to reduce.And these two kinds of systems all need external water source to provide, and the place use for shortage of water resources can be restricted.
For the problems referred to above, the applicant once proposed a kind of electricity and drove compressor station air cooler closed circuit cooling system, and the heat exchanger of frequency converter and motor accesses outer loop chilled water system respectively, and outer loop chilled water system is connected with air cooler.Electricity drives the closed-type circulating cooling water system of cooling employing " air-water cooling device " of compressor station compressor bank motor and frequency converter, the heat produced in motor and frequency converter operation process carries out heat exchange by heat exchanger inner separately and outer loop cold water, and outer loop water carries out heat exchange with air cooler again.This type of cooling solves recirculating cooling water system by problems such as outside water resources condition restriction, waste water resource, scaling, maintenance management difficulties, but its environment for use is restricted: restrict by local environment temperature.
Utility model content
The utility model overcomes shortcoming of the prior art, provides a kind of electricity and drives compressor station water chiller closed circuit cooling system, solves the problem of air cooler closed circuit cooling system environment for use by local environment temperature limiting.
The technical solution of the utility model: a kind of electricity drives compressor station water chiller closed circuit cooling system, comprise frequency converter, motor and outer loop chilled water system, the heat exchanger of described frequency converter and motor accesses outer loop chilled water system respectively, and described outer loop chilled water system is connected with water chiller.
Described water chiller comprises the evaporimeter, compressor, condenser and the expansion valve that are in turn connected into loop.
The heat exchanger of described frequency converter is by frequency converter water cooling unit access outer loop chilled water system.
Compared with prior art, the utility model has the advantages that:
1) this water chiller closed circuit cooling system is not by the restriction of ambient temperature, and the equipment that can be always provides constant cooling water temperature.
2) this water chiller closed circuit cooling system is without water consumption, without blowdown flow rate, environmental, meets the policy that national energy-saving reduces discharging.
3) this water chiller closed circuit cooling system is simple, and the application of its technology substantially increases the reliability of unit operation, considerably reduces on-the-spot operation maintenance workload.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of electricity drives compressor station water chiller closed circuit cooling system, as shown in Figure 1, comprise motor 1, outer loop chilled water system 2, water chiller 3(mainly contain evaporimeter 6, compressor 7, condenser 8 and expansion valve 9 etc.), frequency converter 4, frequency converter water cooling unit 5, wherein:
The heat produced in motor 1 operation process carries out heat exchange by its internal exchanger and outer loop chilled water system 2.
The heat exchanger of frequency converter 4 accesses outer loop chilled water system 2 by frequency converter water cooling unit 5.
Outer loop chilled water system 2 is connected with water chiller 3.Described water chiller comprises evaporimeter 6, compressor 7, condenser 8 and expansion valve 9.In refrigerative circle system, liquid cold-producing medium is vaporization heat absorption in evaporimeter 6 after throttling, reduces the temperature of outer loop water, reaches the object of refrigeration; Then 7, compressor rises to high pressure the refrigerant vapour after heat absorption vaporization from low pressure, and makes it overcome resistance in refrigeration systems constantly to circulate; The superheated steam that refrigeration compressor is discharged is condensed into highly pressurised liquid by condenser 8 again; And then by expansion valve 9 pairs of high pressure liquid refrigerant reducing pressure by regulating flows, make the cold-producing medium under low pressure evaporation endothermic entering evaporimeter 6, reach the object of refrigeration cool-down, and adjustment enters the refrigerant flow of evaporimeter simultaneously, to adapt to the thermic load change of evaporimeter.This cyclic process is just the process of water chiller and the heat exchange of outer loop water.
