Abstract
A kind of half corundum matter micro porous aeration head and manufacture method thereof, its making processes is: emergy, quartz sand, Feldspar Powder, glass powder, aluminium hydroxide, Swim east white clay carries out particle disposal respectively, wherein emergy is crossed 40 mesh sieves, quartz sand is crossed 60 mesh sieves, Feldspar Powder, glass powder, aluminium hydroxide and Swim east white clay are crossed 200 mesh sieves, percentage ratio weighing-emergy 30 by weight then, quartz sand 40, Feldspar Powder 5, glass powder 7, aluminium hydroxide 5, east white clay 13, after stirring, add the starchiness that the methylcellulose gum bath of 0.5%-1% soaks again and stir into wet-milling with viscosity, the swage compacting is adopted in moulding, with blank oven dry back repaired biscuit, 1230 ℃-1270 ℃ of firing temperatures.
Description
The invention belongs to special cermacis technical field class.
Present technology status:
Micro porous aeration head (plate) all carried out development in the U.S., Britain, France and Japan, and had product to sell.The Nore of the U.S. plant-manufactured micro-hole aerator that pauses uses up to a hundred factories.The research group of the Michael of the U.S., Japan little Ji Zhi wild of a specified duration and forever Tian Minxin all have the brilliance achievement.
The micro porous aeration head of the U.S. and Japan development, material are to adopt two kinds of corundum matter and plastics matter.
In China, Beijing municipal administration designing institute is also at the middle micro-pore aeration that begins one's study, development about aeration head, Tianjin oilstone factory, the fire-resistant factory of the big Cheng of Yixing City are manufacturing experimently micro porous aeration head, material is a corundum matter, Yixing big new ceramics factory then is devoted to develop micro porous aeration head, and material is half corundum matter.According to mensuration, the technical feature parameter of micro porous aeration head and half corundum matter micro porous aeration head is entirely different in the corundum matter, and the comparison is as follows:
Micro porous aeration head half corundum matter micro porous aeration head in the corundum matter
Void content 20-25% 40-55%
Aperture 150-200 μ m 100-150 μ m
Micro porous aeration head half corundum matter micro porous aeration head in the corundum matter
Opposing helical pressure 6kg-M 6kg-M
Air flow 1-3m
3/ h 1-3m
3/ h
Service area 0.4-0.5m
2/ 0.6-0.7m
2/
Specific absorption 13-18% 15-25%
Dynamic efficiency 3-6kgO
2/ kWh 4-8kgO
2/ kWh
Above test parameter, micro porous aeration head is by the test of sewage disposal institute of Beijing municipal engineering administration office in the corundum matter, and half corundum matter micro porous aeration head is tested by Shanghai Tongji University water treatment development centre.By comparative analysis, half corundum matter micro porous aeration head has been broken through 0.6m on service area
2/, reach 0.7m
2/, surpassed the U.S., Britain and Japanese standard 0.6m
2/.
Purpose of the present invention then is to develop a kind of half corundum matter micro porous aeration head, is mainly used in the biochemical treatment of sewage.The biochemical treatment of sewage is a kind of economical and effective treatment process, the factor that improves the biochemical treatment effect is a lot, one of important factor wherein, be in the water sufficient dissolved oxygen to be arranged, airborne oxygen is diffused in the water through aerator by the gas blower compression, because the kind difference of scatterer, the effect of oxygenation is also different in water.Under similarity condition and since micro-pore aeration (bubble diameter is less than 2mm) than in air pocket effective, the gas-liquid area that contacts is big, the oxygen absorption rate increases, dynamic efficiency, consumed energy are little.And in active sludge, the aerating system power consumption at most, the power power consumption of aerator accounts for 70% of total power consumption, under various countries' energy-intensive situation, the aerator (micro-pore aeration) of research high-level efficiency low power consuming, thus the running expense that reduces sewage work is very significant.
Technical solution of the present invention:
1, composition of raw materials (percentage ratio by weight):
Emergy 20-40
Quartz sand 30-50
Feldspar Powder 5-10
Glass powder 3-8
Aluminium hydroxide 3-5
Swim east white clay 8-15
Methylcellulose gum 0.5-1
2, making processes:
More than various raw materials carry out particle disposal respectively, wherein emergy is crossed 40 mesh sieves, quartz sand is crossed 60 mesh sieves, Feldspar Powder, glass powder, aluminium hydroxide and Swim east white clay and crossed 200 mesh sieves, with above-mentioned raw materials weighing in proportion, stir, the starchiness that soaks of methylate Mierocrystalline cellulose bath stirs into the wet-milling with viscosity again, the swage compacting is adopted in moulding, and available 40-60 ton friction press is with blank oven dry back repaired biscuit, 1230 ℃-1270 ℃ of firing temperatures are the check finished product then.
Advantage of the present invention:
Half corundum matter micro porous aeration head has been broken through 0.6m on service area
2/, reach 0.7m
2/, half corundum material helps sintering, and compares with corundum matter, has significantly to descend on production cost.Technological operation of the present invention is simple, and the market potential of product is very big.
Embodiment:
Emergy 40 order 1500g, quartz sand 60 order 2000g, Feldspar Powder 200 order 300g, glass powder 200 order 300g, Al(OH)
3200 order 250g, Swim east white clay 200 order 650g, evenly mixed, methylcellulose gum 50g, add water 750g, stir into starchiness, pour into then in the blended stock, continue to be blended into the wet-milling of viscosity, claim 1250g the swage of packing into wet-milling, with 60 tons of press once shapeds, then the oven dry burn till to 1250 ℃, product.
