Embodiment
[0017] Example: The working process of the present invention is as follows: the air above 100°C at the outlet of the air compressor 8 is directly introduced into the air cooling tower 2, and flows from bottom to top. Cooling water is sprayed from top to bottom. The gas and water flow in reverse, fully contacted by the filler, and the rising compressed air is cooled to 10°C-32°C according to the season, specifically: winter: 10°C-15°C, the best control is 12°C; summer: 25°C-32°C , the best control is 28°C; spring and autumn: 15°C~25°C, the best control is 20°C, and then it is drawn from the top of the air cooling tower 2, and is heated to 30°C~38°C by the end reheater 1 according to the season and then enters the tube network. The temperature of the compressed air entering the pipe network can be adjusted by controlling the flow rate through the first valve 11 . There are two upper and lower sections of cooling water. The cooling water in the upper section first enters the ...

The invention discloses a concentrated compressed air spraying, cooling and drying system, a top outlet of an air cooling tower is connected with an inlet of a tail-end reheater, outlets of the tail-end reheater and an air compressor are connected with a lower-end inlet of the air cooling tower through a first valve, another outlet of the tail-end reheater is connected with a compressed air pipe network, a filter screen is arranged on the inner lower end of the air cooling tower, the lower-end outlet of the air cooling tower is connected with a water cooling tower through a water level adjustment valve, the water cooling tower is connected with a water pump through a second valve, the water pump is connected with a lower-section nozzle and an inlet of a freezer through a third valve, and an outlet of the freezer is connected with an inlet of an upper-section nozzle. High-temperature gas at the outlet of the air compressor directly enters the air cooling tower for cooling, and the resistance of the gas at the outlet of the air compressor is reduced; the energy consumption of the compressor is also reduced; gas and water are directly contacted through spray cooling, so that impurities in the air can be washed off, so that the compressed air is cleaner, and the running efficiency of equipment can be improved.
Description
technical field [0001] The invention relates to a compressed air dehydration and drying technology, in particular to a compressed air centralized spray cooling and drying system. Background technique [0002] In steel, textile and other industries, compressed air is widely used as an energy medium, such as: used as air source for pneumatic valve instrumentation, power air source, cooling air source, purge air source, etc. a link. Different users have different requirements for the dryness of the air source, but most of the occasions require that the air source does not contain visible moisture, that is, the relative humidity is less than 60%, which can fully meet the demand. [0003] The current compressed air drying process mostly adopts the method of adsorption or freezing, and there is also the method of first cooling through the freezer and then adsorption. The drying facilities are generally arranged at each compressed air supply station, and each user site also sets u...
