By adopting the tepidity regeneration adsorption type dryers, the system can completely meet the requirements of a production process, has a few components and a good drying effect, is convenient to maintain, and is particularly suitable for a nitrogen manufacturing system in a gas protective station system.
Description
Technical field
The utility model belongs to metallurgical type of sheet material manufacture field, relates to a kind of compressed air drying system, is particularly suited for the nitrogen manufacturing system in the system of gas shield station.
Background technology
Nitrogen manufacturing system of the prior art is made up of three air compressors, air reservoir, three cover pressure varying adsorption nitrogen making systems, nitrogen storage tank, some stop valves.Pressure varying adsorption nitrogen making system is by fore filter--oil removing and dewater, refrigerated type air dryer, post-filter, varying-voltage adsorption nitrogen machine form.Air is delivered to buffering, voltage stabilizing in the air reservoir after the air compressor compression; Remove oil content, moisture and impurity in the compressed air through fore filter; Get into the refrigerated type air dryer cryogenic refrigeration and dewater, filter, separate into nitrogen and oxygen through varying-voltage adsorption nitrogen machine again by post-filter; Nitrogen is sent into buffering, voltage stabilizing in the nitrogen storage tank, and oxygen emits.Air compressor and pressure varying adsorption nitrogen making system all are dual-purpose one to be equipped with.Find that in process of production refrigerated type air dryer effect in the winter time is best, summer, particularly overcast and rainy effect was the poorest.Shortcomings such as along with the growth of service life, on the one hand drying effect descends, and refrigerated type air dryer line clogging on the other hand, compressor fault, maintenance cost are high, strongly professional have all exposed.
Summary of the invention
The utility model problem to be solved is, overcomes the deficiency of prior art, and a kind of compressed air drying system is provided, and adopts low-grade fever regeneration absorption type drying machine, can satisfy manufacturing technique requirent, the good stability of drying effect.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of compressed air drying system that provides according to the utility model; Comprise air compressor, precooler, fore filter, low-grade fever regeneration absorption type drying machine, post-filter, air reservoir, pressure change adsorption type nitrogen making machine and nitrogen storage tank; Described three air compressors connect three gas circuits respectively; With three gas circuits and be unified into two gas circuits, two gas circuits be linked in sequence respectively precooler, fore filter, low-grade fever regeneration absorption type drying machine, post-filter, the two-way gas circuit is again and be unified into a gas circuit and connect air reservoir; Air reservoir divides three gas circuits to connect the pressure change adsorption type nitrogen making machine respectively; Three gas circuit parallel connections of three pressure change adsorption type nitrogen making machines are connected with nitrogen storage tank, and nitrogen storage tank connects a gas circuit, all is connected with stop valve in the gas circuit.
The utility model compared with prior art has significant advantage and beneficial effect:
Because utility model adopts low-grade fever regeneration absorption type drying machine, can satisfy manufacturing technique requirent fully, parts are few, and are easy to maintenance, and professional not strong, drying effect is good, and stability is high.
The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, air compressor 2, stop valve 3, air reservoir 4, fore filter 5, low-grade fever regeneration absorption type drying machine 6, post-filter 7, varying-voltage adsorption nitrogen machine 8, nitrogen storage tank 9, precooler.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment, structure, characteristic and the effect thereof that provides according to the utility model, specify as after.
As shown in Figure 1 a kind of compressed air drying system; Comprise air compressor, precooler, fore filter, low-grade fever regeneration absorption type drying machine, post-filter, air reservoir, pressure change adsorption type nitrogen making machine and nitrogen storage tank; Described three air compressors 1 connect three gas circuits respectively; With three gas circuits and be unified into two gas circuits, two gas circuits be linked in sequence respectively precooler 9, fore filter 4, low-grade fever regeneration absorption type drying machine 5, post-filter 6, the two-way gas circuit is again and be unified into a gas circuit and connect air reservoir 3; Air reservoir divides three gas circuits to connect pressure change adsorption type nitrogen making machine 7 respectively; Three gas circuit parallel connections of three pressure change adsorption type nitrogen making machines are connected with nitrogen storage tank 8, and nitrogen storage tank connects a gas circuit, all is connected with stop valve 2 in the gas circuit.
Selecting low-grade fever regeneration absorption type drying machine for use is because of its drying effect is close with refrigerated type air dryer, can satisfy manufacturing technique requirent fully, and parts are few, easy to maintenance, professional not strong, and the stability of drying effect is superior to refrigerated type air dryer.Because of the intake air temperature of low-grade fever regeneration absorption type drying machine requires to be controlled at below 40 ℃, compressed-air actuated temperature is lowered so precooler is installed before it; Consider its requirement, between precooler and low-grade fever regeneration absorption type drying machine, fore filter is installed oil content in the compressed air and moisture; Installing post-filter additional thereafter is in order to guarantee to get into the compressed-air actuated quality of varying-voltage adsorption nitrogen machine.The displacement of low-grade fever regeneration absorption type drying machine is big when considering dark and damp weather, and does not allow steam to send forth in the gas shield station, and the draining diffuser on it is strengthened and only at the one side pore that begins to rehearse towards ground, when pipeline connects laggard capable air-tightness experiment.
