A kind of filter type air drying machine
Technical field
The present invention relates to a kind of filter type air drying machine.
Background technology
In economic growing today, almost each industrial production factory is required to compressed air, compressed air into For a kind of essential power source.And as the needs of scientific technological advance, industrial production and industrial products are to the matter of source of the gas Amount has higher requirement, and then arise at the historic moment various air cleaning facilities.Waterside town device in compressed air is pneumatic system The maximum hidden danger of normal work, in pneumatic system purification process, compressed air drying is most important, and is what this was paid Cost price is also highest, while can also produce noise and dust.
The compressed air drier that the country generally uses now is all to use freezing type or heating type drier to carry out, cold Jelly formula drying machine is using compressor of air conditioner principle freeze condensing the drying for being compressed air, and drying effect is poor and uses Electric energy consumption is high, and heating type drier is then air-dried using electrically heated mode, but electric energy energy consumption is very high, and both are dry Although the use of dry machine can carry out removal moisture drying to air, and air can not be filtered while drying, cause Dried air still has peculiar smell, does not also reach Products while not only the electricity consumption energy consumption cost to company brings pressure Requirement to compressed air dew point quality.For president, there is drying effect is poor, high energy consumption and makes for existing dried-air drier The shortcomings that with short life.
The content of the invention
In view of this, it is an object of the present invention to provide a kind of oxidation that saturation is separately filled with interconnected two tank bodies Aluminium porcelain ball and undersaturated alumina ball, can be to being air-dried, while is also filtered, it is possible to increase the clean journey of air Degree, and have a regeneration function for the change aluminium porcelain ball of filtration drying air, sustainable use, therefore with drying effect is good, energy Consume the filter type air drying machine of low and service life length.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of filter type air drying machine, including inlet duct, and be arranged on inlet duct side and and inlet duct Connection, the first drying chamber for carrying out filtration drying to air, and be arranged on the first drying chamber side and with it is first dry The connection of dry tank, communication apparatus for conveying air, and be arranged on communication apparatus side, for being filtered dry to air The second dry drying chamber；First drying chamber includes the first tank body, and be filled in the first tank interior, for entering to air The saturation porcelain ball of row filtration drying；Second drying chamber includes the second tank body, and be filled in the second tank interior, for pair Air carries out the unsaturated porcelain ball of filtration drying, and be arranged on the side-lower of the second tank body one and connect with the second tank body, use In the outlet of export dry air.
Further, first tank body is stainless steel tank body, and the bottom of the first tank body is provided with sewage draining exit.
Further, second tank body is stainless steel tank body, and the bottom of the second tank body is provided with pressure relief opening.
Further, the saturation porcelain ball and unsaturated porcelain ball are all alumina ball.
Further, raw material of the alumina ball including following parts by weight proportioning is made：Alumina powder 50-80 Part, flint clay clinker 10-16 parts, kaolin 17-23 parts, rare-earth yttrium 4-7 parts, calcium carbonate 11-16 parts, forsterite sand 7-12 Part, carbon black 6-9 parts, activated carbon 20-28 parts, potassium feldspar 13-18 parts, silica 6-8 parts, molybdenum nickel powder 2-4 parts, cobalt nickel powder 2-4 parts, Tungsten nickel powder 2-4 parts, Herba Menthae powder 14-20 parts, high molecular surfactant 4-6 parts and complex sintering aids 3-5 parts.
Further, the high molecular surfactant is in hydroxypropyl cellulose, cationic modified starch, chitosan One or more kinds of mixtures.
Further, the complex sintering aids are silicon nitride.
Further, the inlet duct includes body, and be arranged on body head end and with body fix air enter Mouthful, and muffler that is in the middle part of body and being connected with body is arranged on, the lower end of the air intlet is provided with for controlling sky The valve that gas enters.
Further, the communication apparatus includes communicating pipe, and is arranged on the heater in the middle part of communicating pipe, and is arranged on One tank interior and the extension that is connected with communicating pipe.
Another technical problem to be solved by the invention is to provide a kind of preparation method of alumina ball, including following step Suddenly：
1) alumina powder 50-80 parts, flint clay clinker 10-16 parts, kaolin 17-23 parts, rare-earth yttrium 4-7 parts, carbonic acid are taken Calcium 11-16 parts, forsterite sand 7-12 parts, carbon black 6-9 parts, activated carbon 20-28 parts, potassium feldspar 13-18 parts and silica 6-8 parts It is added in ball mill, the ball milling processing of 12-18 hours is persistently carried out by ball mill so that above-mentioned material is in mechanical milling process It is well mixed, the mixed-powder of 500 mesh is made, it is standby；
2) take molybdenum nickel powder 2-4 parts, cobalt nickel powder 2-4 parts and tungsten nickel powder 2-4 parts to carry out ball milling using ball mill, 500 mesh are made Mixing fine powders, and be added in dryer and dry, be subsequently placed in calcining furnace that calcining 10 is small at a temperature of 900-1100 DEG C When, mixed catalyst is made, it is standby；
3) mixed-powder made from step 1) is taken to be added to mixed catalyst made from step 2) in mixer, startup is stirred Mix machine to be stirred with 30r/pm rotating speed so that mixed-powder and mixed catalyst are well mixed, while are noted into agitator Enter mixed-powder and twice of water purification of mixed catalyst weight sum, while add Herba Menthae powder 14-20 parts, high molecular surfactant 4-6 parts and complex sintering aids 3-5 parts so that Herba Menthae powder, high molecular surfactant and complex sintering aids mixing water purification with Mixed-powder and mixed catalyst are well mixed, and underflow is made, standby；
4) by underflow made from step 3) by draining after, obtain walk, then using static pressure machine isostatic pressed state Machine-shaping, base substrate is made, is then cut by guillotine in the square briquet that the length of side is 2mm, it is standby；
5) square briquet made from step 2) is transported in granulator, starts chicken granulator and revolved with 35r/pm rotating speed Turn so that square briquet becomes balling-up base, standby；
6) ball base made from step 5) is placed in high temperature tile kiln, pressureless sintering is carried out at 1150-1700 DEG C, continued Sintering 3-5 days, then natural cooling, is made the ball base of high rigidity, standby；
7) ball base made from step 6) is polished processing by polishing machine so that ball base surface is smooth, produces.
8) renovation process of alumina ball：Alumina ball after saturation is inserted in 100g/L aluminum sulfate solution and soaked 30h is steeped, solution is then discarded, is washed 3-5 times with clear water, use water 2L every time, then drying can reuse.
The technology of the present invention effect major embodiment is in the following areas：Saturation is separately filled with two tank bodies that are interconnected Alumina ball and undersaturated alumina ball, removal moisture drying can carried out to air, while also filtered, it is adsorbable to go Except fluorine harmful in air, the also adsorbable arsenic removed in air, peculiar smell etc., the cleaning of air can be further improved Degree, there is the advantages of drying effect is good, and there is regeneration function for the alumina ball of filtration drying air, it is sustainable Use, improve and be capable of the service life of dried-air drier, furthermore the application by air pressure air inlet, and during air transmits Air dewetting processing is carried out, therefore there is the advantages of energy consumption is low.
