Abstract
The utility model provides an energy-saving treatment system for high-flow compressed air. The energy-saving treatment system for high-flow compressed air comprises a buffering tank and an adsorption dryer which are sequentially connected with an air compressor, wherein a pre-cooler and an air-water separator are arranged between the buffering tank and the adsorption dryer. According to the energy-saving treatment system provided by the utility model, compression heat generated during an air compression process is mainly exhausted through circulation cooling water of a cooling tower so as to reduce the load of a water cooling unit, and thus the system has an energy-saving effect; in addition, compressed air is cooled to be at a low temperature, and most of water in the compressed air is drained during a pre-cooling process and a condensing separation process of the air-water separator, so that the requirement of the adsorption dryer on the inlet temperature of compressed air is met, the load of the adsorption dryer is reduced, and the adsorbent regeneration heating energy consumption of an adsorption dryer unit is saved; the switching interval of the system is up to 8 hours, the working period of the system is 16 hours, and as the switching frequency is low, the fault rate is decreased, and the life of the system is prolonged; the system can stably provide dry compressed air with a pressure dew point lower than -70 DEG C all the year round.
Description
Technical field
The utility model relates to compressed-air actuated technical field of drying, particularly the compressed-air actuated energy-efficient treatment system of a kind of large flow.
Background technology
Conventional compression air treatment system is, after compressed air is discharged by air compressor machine supercharging, to be filtered, and directly enters the dew point that adsorption dehumifier is processed needs.Although the demand ratio of the p-40 ℃ of dew point gases of this treatment system is easier to reach; But the demand of p-70 ℃ of dew point gases, is difficult to reach, summer particularly, owing to entering, the compressed air temperature of adsorption dry is higher, therefore, is difficult to reach desired lower dew point.
For above-mentioned situation, be on the aftercooler configuring in pneumatics unit traditionally, cooling with chilled water; This systematic comparison is applicable to low discharge air-treatment; Yet concerning mass flow air is processed, need to consume the huge energy, make the heat of compression that originally can discharge by cooling tower, but need to discharge the heat of compression by chilled water system, increase installation scale and the operating cost of chilled water system.In addition, can adopt between air compressor machine and adsorption dehumifier, add freeze drier, but exist plant machinery fault many, and the large shortcoming of energy consumption.
How a kind of compressed-air actuated system that can obtain stable lower dew point is provided energy saving economy, is a problem demanding prompt solution.
Utility model content
In view of the above problems, the utility model provides a kind of large flow compressed-air actuated energy-efficient treatment system, can make economically Compressed Gas reach lower dew point.
The utility model provides a kind of large flow compressed-air actuated energy-efficient treatment system, comprises the surge tank and the adsorption dehumifier that by pipeline, are connected successively with air compressor machine, between described surge tank and adsorption dehumifier, is provided with precooler.
Wherein, on the pipeline between described precooler and adsorption dehumifier, be also provided with the moisture trap being connected with described precooler.
Wherein, described precooler is for using the middle temperature chilled water of 14 ℃ to carry out cooling precooler.
The utility model passes through on the one hand by the air press of circulating cooling water cooling, and the main still maintenance of the heat of compression in compressed air is discharged by cooling tower, alleviates the load of handpiece Water Chilling Units, makes system more energy-conservation.
The utility model on the other hand can be pressure-air cooling to lower temperature, make the moisture in compressed air, the overwhelming majority is discharged from precooling process and moisture trap condensation separation process, both guaranteed the requirement of adsorption dehumifier to compressed air inlet temperature, the adsorption dehumifier load having alleviated again, saves adsorption dry unit adsorbent reactivation heating energy consumption.Can reach 8 hours its switching time, machine cycle 16 hours.Switching frequency is low, reduces fault rate, the extension device life-span.
The utility model is cooling by warm chilled water in adopting, and compressed air is processed to 20 ℃, then enter adsorption dehumifier, can stablize throughout the year and provide pressure leak source lower than the dried compressed air of-70 ℃.
Accompanying drawing explanation
Fig. 1 provides the structural representation of the compressed-air actuated energy-efficient treatment system of a kind of large flow for the utility model.
The specific embodiment
Below in conjunction with embodiment, describe the utility model in detail, referring to Fig. 1, the compressed-air actuated energy-efficient treatment system of a kind of large flow that the utility model provides comprises: the centrifugal air compressor 1 connecting successively by pipeline, surge tank 2, precooler 3, moisture trap 4, fore filter 5, drying device 6, post-filter 7 and fine filter 8.
By fore filter 5, drying device 6, post-filter 7 and fine filter 8, form adsorption dehumifier.
Between centrifugal air compressor 1 and the adsorption dehumifier of blast heating zero loss, precooler 3 and moisture trap 4 are set.The cooling whole employing cooling tower circulating cooling water coolings of centrifugal air compressor 1 inter-stage, then pass through surge tank by compressed air delivery in precooler 3, precooler 3 is for using the middle temperature chilled water of 14 ℃ to carry out cooling precooler.By precooler 3, compressed-air actuated Temperature Treatment to 20 ℃.
Afterwards, dew point is obtained to the preliminary compressed air delivery reducing in moisture trap 4, by moisture trap 4, remove the condensed steam in compressed air.
Compressed air in moisture trap 4 is transported in adsorption dehumifier again, and in the present embodiment, adsorption dehumifier comprises fore filter 5, drying device 6, post-filter 7 and fine filter 8.Compressed air is after fore filter 5, drying device 6, post-filter 7 and fine filter 8, and user obtains the dried compressed air of stable-70 ℃ of dew point.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; any modification based on doing within spirit of the present utility model and principle, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
