Abstract
The utility model discloses an air cooler closed circulating cooling system for an electric-driving compressor station. Heat exchangers of a frequency changer and a motor are respectively connected to an external circulating water cooling system, and the external circulating water cooling system is connected with an air cooler. The heat exchanger of the frequency changer is connected to the external circulating water cooling system through a frequency changer water cooling unit. The air cooler closed circulating cooling system for the electric-driving compressor station has the advantages of resolving problems existing in a conventional circulating cooling system, being free of water consumption and discharge capacity, being favorable for environment protection, according with the national policy of energy conservation and emission reduction, being simple and easy to achieve, largely improving the reliability of unit operation, and largely lightening work load of operation maintenance on site.
Description
Technical field
The utility model relates to a kind of electricity and drives compressor station air cooler closed circuit cooling system.
Background technology
In the Long-distance Transmission Pipeline field, electricity drives compressor station because of the needs of natural gas transmission technique, gas compressor set need be set carry out supercharging.And supporting variable-frequency motor and the frequency converter of compressor bank can produce a large amount of heats in the unit pressurization, in time taking away this part heat, guarantees unit safety operation, needs to be its design configurations one cover cooling system in Practical Project.General, the most conventional way is to adopt the recirculating cooling water system of open cycle cooling water system or closed cooling tower at present.But practical experience for many years proves these two kinds of systems and all has many drawbacks.There are the disadvantages such as scaling, bacterium algae grow, water resource waste, maintenance management difficulty, system complex in the open cycle cooling water system, brings inconvenience to operational management; And the cooling coil of the recirculating cooling water system of closed cooling tower is in the situation that compressor bank stoppage in transit in winter is frequent because of the icing spalling of the cooling water in coil pipe; PVC filler in cooling coil outer surface and tower body is easily fouling under summer high temperature weather, causes the cooling tower cooling effectiveness greatly to reduce.
The utility model content
The utility model has overcome shortcoming of the prior art, provides a kind of electricity to drive compressor station air cooler closed circuit cooling system, has solved the problems that exist in the regular circulation cooling system.
The technical solution of the utility model is: a kind of electricity drives compressor station air cooler closed circuit cooling system, and the heat exchanger of frequency converter and motor accesses respectively the outer loop chilled water system, and the outer loop chilled water system is connected with air cooler.
The heat exchanger of 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 air cooler closed circuit cooling system is without water consumption, and is environmental without blowdown flow rate, meets the policy that national energy-saving reduces discharging.
2) this air cooler closed circuit cooling system is simple, and the application of its technology has improved the reliability of unit operation greatly, has greatly reduced on-the-spot operation maintenance workload.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of electricity drives compressor station air cooler closed circuit cooling system, as shown in Figure 1, comprises frequency converter 1, frequency converter water cooling unit 2, outer loop chilled water system 3, air cooler 4, motor 5, wherein:
The heat exchanger of frequency converter 1 and motor 5 accesses respectively outer loop chilled water system 3, and outer loop chilled water system 3 is connected with air cooler 4.
The heat exchanger of frequency converter 1 also can be by frequency converter water cooling unit 2 access outer loop chilled water systems 3.
Operation principle of the present utility model is: electricity drives the closed-type circulating cooling water system of the cooling employing " air-water cooling device " of compressor station compressor bank motor and frequency converter.The heat that produces in motor and frequency converter operation process carries out heat exchange by inner separately heat exchanger and outer loop cold water, and outer loop water carries out heat exchange with air cooler again.
Claims (2)
1. an electricity drives compressor station air cooler closed circuit cooling system, and it is characterized in that: the heat exchanger of frequency converter and motor accesses respectively the outer loop chilled water system, and the outer loop chilled water system is connected with air cooler.
2. electricity according to claim 1 drives compressor station air cooler closed circuit cooling system, it is characterized in that: the heat exchanger of frequency converter is by frequency converter water cooling unit access outer loop chilled water system.
