Description

A kind of zero gas consumption compressed air drier by afterheat regeneration
Technical field
The present invention relates to a kind of zero gas consumption compressed air drier by afterheat regeneration.
Background technology
Compressed air because having the characteristics that easily to store, easy to control, good fluidity and safe and environment-friendly, be only second to electric power Second power source is widely used in many fields such as food, electric power, chemical industry, pharmacy, mining and machine-building.Application Field is different, also different to the quality requirement of compressed air, but be unable to do without efficient, energy-saving and environmental protection themes always.
Air is after compressor compresses, so that it may obtain the compressed air with elevated pressures.But due to air compressor Itself contains lubricating oil, when carrying out compression work, necessarily has parts of lubricating oil to be mixed into compressed air, in addition, natural The air on boundary itself also contains some solid particles and moisture etc., and therefore, the compressed air generated by compressor is not pure 's.This air without purified treatment is directly used in pneumatic circuit, pneumatic circuit can be made to break down, be damaged pneumatic group Part reduces component service life, and production efficiency declines, or even causes the accident.According to statistics, the disorderly closedown of pneumatic system has 85% It is due to the use of caused by compressed air that is unholiness, not drying above.To find out its cause, the moisture in compressed air can cause portion Part corrosion, winter can condense icing, result in blockage；Oil gas condensation precipitate to be formed greasy dirt often result in sealing element aging, failure；Powder Dirt then accelerates the abrasion of moving parts, and deposition results in blockage, and causes the meaningless pressure loss etc..Therefore, these compressions are purified Air is an essential important link in baric systerm to obtain pure compressed air.
Wherein, it is exactly moisture contained in compressed air to influence maximum factor to pneumatic system.Moisture is in surrounding air In be widely present, can not completely remove, after this part water enters compressor compresses, due to the variation of temperature, pressure, will have cold Condensate is precipitated, and seriously affects operation and the function life-span of other gas equipments of Compressor Group, therefore removes the water in air It is very necessary to divide.
Drying is opposite, that is, is considered as dry air in certain demand, is regarded as not in other purposes Enough dryings.Therefore, compressed air needs the drying of which kind of degree, first when being design or selection drying machine which kind of demand met The factor to be considered.Because selection need not too low dew point drying machine, will increase buying and operating cost.According to above several Different theoretical methods, the compressed air drying method developed and used at present include mainly following several：
（1）It is adsorbed by drying method：
Method is adsorbed by drying using adsorbent to the absorption property of moisture, such as silica gel, activated alumina and molecular sieve etc., they are to water Dividing all has very strong adsorption capacity.The moisture absorption process of adsorbent is physical change, is reproducible, adsorbs under high pressure, low Pressure desorption, i.e. pressure-variable adsorption（PSA）；Also it can be adsorbed in normal pressure, when heating regenerates, i.e. temp.-changing adsorption（TSA）；Or high pressure is normal Temperature absorption, constant-pressure and high-temperature desorption（PTC）.This kind of aridity being adsorbed by drying can reach -70 DEG C of dew points at normal pressure.
（2）Deliquesce seasoning：
Deliquescence formula drier, to the characterization of adsorption of moisture, only deliquesces the adsorbent of formula in adsorption moisture also with adsorbent Afterwards, become liquid discharge, the adsorbent after deliquescence cannot regenerate, and can cause environmental pollution.This method is also known as chemistry Method.This kind of drier can reach -38 DEG C or so of dew point.
（3）Freeze-drying：
Freeze-drying is that the cold generated using refrigeration compressor cools down compressed air, and compressed air is made to reach its pressure Dew-point temperature corresponding to power reaches drying purpose to make the moisture in compressed air be precipitated.The aridity of this kind of seasoning - 23 DEG C of dew points at normal pressure can be reached.
（4）UF membrane seasoning：
It is a kind of extremely promising drying mode that compressed air, which is dried, using membrane separation technique.Compressed air is by hollow When fiber membrane, the osmotic pressure of each substance is different, so that water is separated from compressed air, to reach drying effect.
Existing compressed air drying method generally existing operating cost is high, absorption material expends big, service life of equipment The shortcomings of short, and its drying effect is also difficult to meet the higher and higher use gas requirement of equipment.For this reason, it may be necessary to find new method This problem is solved with approach.
Invention content
In order to solve many deficiencies in the prior art, the present invention provides a kind of zero gas consumption residual heat regenerating compressed air is dry Dry device, the system include compressed air inlet, ultraviolet catalyzed oil expeller, adsorption tower, thermoelectric converter, accumulator, heating Controller, electric heater, external power supply, cooler A, gas-liquid separator A, cooler B, gas-liquid separator B, bag filter, Drying compressed air exports and 5 sets of shut-off valves.Wherein, it after air enters this system by compressed air inlet, initially enters Ultraviolet catalyzed oil expeller, the air path after its deoiling treatment are divided into A, B two-way, and the connection type on the roads A is：Air according to It is secondary by shut-off valve A, thermoelectric converter, shutoff valve C, eventually enter into adsorption tower；The connection type on the roads B is：Air passes sequentially through Shut-off valve B, cooler B, gas-liquid separator B, shut-off valve D, eventually enter into adsorption tower.Wherein, compressed air outlet gas flow path is one Road, air pass sequentially through cooler A, gas-liquid separator A, bag filter, are finally exported and are sent out by drying compressed air, conveying To gas equipment.Wherein, gas-liquid separator A and gas-liquid separator B are respectively equipped with automatic drain valve and Manual draining valve.Its In, the transport path of electric energy is：The electric energy that electric energy caused by thermoelectric converter and external power supply provide, is deposited into accumulator Storage, and the electric heater inside adsorption tower is conveyed to after the regulation and control of heated controller.Wherein, outside ultraviolet catalyzed oil expeller Cover is stainless steel, and bottom and top are respectively equipped with air intake valve and drain tap, is internally provided with 1 ultraviolet light and occurs Device, and it is individually fixed in equipment quadrangle by 4 fixing brackets, ultraviolet light generator passes through two sections of connecting wires and device external Electric control gear be connected, be enclosed with tungstic acid catalysis net on the outside of ultraviolet light generator.Compressed air containing mineral oil passes through Air intake valve positioned at ultraviolet catalyzed oil expeller bottom enters inside equipment, air and three oxygen being fixed on inside reaction unit Change tungsten catalysis net to be in contact, at this point, regulation and control of the ultraviolet light generator among tungstic acid catalysis net in electric control gear Lower start-up operation, ultraviolet light is emitted into whole equipment, under ultraviolet wavelength irradiation condition, the tungsten atom in tungstic acid Meeting Ultraviolet radiation absorbing, low-lying level electrons are optically excited, and energy level transition occurs, while being generated accordingly on original cost band Hole to generate a large amount of free radicals, and the mineral oil component exhaustive oxidation in air is cracked, and primary product is water vapour And carbon dioxide, the compressed air after deoiling treatment is discharged through the drain tap at the top of equipment, into next treatment process.
The complete working period of this system is divided into following two stages：
