Detailed description of the invention
Embodiment
See Fig. 1, it is illustrated that in pipe heat exchanger with the water-cooled air compressor in background technology or water-cooled cooling driers be Example illustrates, but the heat exchanger applied of this utility model is not limited only to the equipment of foregoing description.
In air compressor machine/cooling driers 1, its internal heat pipeline passes through cooling water inlet pipe 2 and CWR 3 with cold But water circulation system 4 is linked to be loop, and cooling water recirculation system includes that the cooling water pump of heat exchanger send and cooling module, for heat exchanger Routine techniques, do not repeat at this.
The present embodiment is arranged by three way cock 5 on the cooling water inlet pipe 2 and CWR 3 of heat exchanger respectively Connecting tube 6, this connecting tube uses the hard tube of φ 20, two connecting tubes respectively by abluent outlet pipe 9 and abluent backwater Pipe 10 is linked to be loop, and arranges pump 11 and the reserving liquid tank 12 of series connection on this loop, is provided with the first valve 7 in connecting tube 6, It is respectively equipped with the second valve between three way cock 5 and circulating water cooling system on cooling water inlet pipe 2 and CWR 3 8, when air compressor machine/cooling driers 1 normally works, the first valve 7 is closed, and the second valve 8 is opened, now on-line cleaning device not work Making, cooling water recirculation system 4 is circulation in cooling water inlet pipe and CWR;To in air compressor machine/cooling driers 1 Pipeline when carrying out on-line cleaning, the first valve 7 is opened, and the second valve 8 is closed, and now pump 11 pumps cleaning from reserving liquid tank 12 Liquid, sends into abluent, then from cooling water backwater from cooling water inlet pipe by abluent outlet pipe 9 and connecting tube in pipeline Pipe is flow back in reserving liquid tank by connecting tube and abluent return pipe 10, it is achieved the online circulation of air compressor machine/cooling driers 1 interior conduit Clean.
