Abstract
The present invention provides a deodorization drying agent with low cost, which has the components (by weight percentage): 45 to 75% of pulverized coal ash, and 18 to 53% of CaSO4 of gypsum or 2 to 7% of lime of gypsum. The deodorization drying agent can additionally have an activating agent of which the content is 0.1/1000 to 0.4/1000 of the total content of the deodorization drying agent as required, wherein the activating agent has the components of 67 to 70% of CaO, 10 to 12% of MgO, 2 to 5% of Al2O3, 10 to 15% of SiO2, 0.12 to 0.3% of Fe2O3 and 0.2 to 2.5% of K2O. Moreover, the activating agent can also contain other calcium salt, carbonaceous organic materials, etc. The preparation method is characterized in that the raw materials are mixed based on the proportion, and 30 to 45 portions of water is added to every 100 portions of mixture (dry weight); after the water and the mixture are mixed evenly, a column with a diameter of 3 to 10mm and a length of 5 to 30mm is produced by a forming machine; and a product is formed by drying.
Description
Technical field
The present invention relates to a kind of deodorizing desiccant and preparation method thereof, especially relate to a kind of low, effective deodorizing desiccant of wide material sources, cheap flyash and an amount of gypsum and the mixed cost of making of lime and preparation method thereof that adopts.
Background technology
Drier is widely used in daily life, industrial production and scientific research, is the drier of using always as silica gel, anhydrous calcium chloride, the concentrated sulfuric acid etc.In the daily life, deodorant also has a large amount of application, such as pet deodorizing and other deodorizing aspects such as deodorizing between deodorant for refregerator, animal feeding, cat and dog.Common in the market deodorizing desiccant is in the majority with the active carbon goods, and its manufacture craft is loaded down with trivial details, and cost of manufacture is often higher.Patent retrieval is found, someone applied for by name " deodorant and method for making thereof; and deodorizing method " (96190047.4), this deodorant is with by cupric oxide, the deodorizing composition that manganese oxide and silver nitrate constitute, carrier band forms on the carrier substrate that with the active carbon is principal component, particularly, cupric oxide, the ratio of components of manganese oxide and silver nitrate: cupric oxide, calculating by CuO is 0.5～10 weight portion, manganese oxide, by MnO#-[2] to calculate be 1～20 weight portion, silver nitrate is by AgNO#-[3] calculating is 1～20 weight portion, and the cupric oxide in the deodorant, the total content of manganese oxide and silver nitrate is 3～30 weight %.A kind of in addition " chemical hygroscopic drying agent and preparation method thereof " (94111758.8), CaO, K#-[2 are arranged in the drier] O, Na#-[2] O, Na#-[2] SiO#-[3], SiO#-[2], Ca (OH) #-[2], MgO, wherein all the other are auxiliary material except that CaO is major ingredient, adopt 95% above high-purity C aCO#-[3 during preparation] ore selected pulverizing after high-temperature calcination is irregular multiangular particle, forms by the formulated spraying slurries of auxiliary material in the spraying.
On the other hand, China is state of coal production in the world and country of consumption, according to statistics, coal accounts for 75% of disposable total energy consumption, especially produce a large amount of byproduct flyash in coal-burning power plant and large-sized boiler factory, its utilization rate is very low at present, has caused the very big wasting of resources.The present invention is intended to make full use of cheap flyash, and mixed suitable gypsum, lime and activator made low-cost deodorizing desiccant.
Summary of the invention
The present invention mainly is that the common deodorizing desiccant of solution is higher to ingredient requirement, manufacture craft is loaded down with trivial details, the technical problem of the often higher grade of cost of manufacture.
The present invention solves above-mentioned technical problem by following proposal: the composition in this low-cost deodorizing desiccant ratio of components preferably is (weight ratio):
Flyash 40-80%
Gypsum (is pressed CaSO
4Meter) 13-58%
Lime 2-7%
In addition, add the activator that first three plants amount of the mixture 0.1 ‰-0.4 ‰ again.The composition of described activator is CaO, MgO, Al
2O
3, SiO
2Carbonaceous organic material Deng inorganic matter and trace.
Generally speaking, the composition of described activator is: CaO 67-70%, MgO 10-12%, Al
2O
32-5%, SiO
210-15%, Fe
2O
30.12-0.3%, K
2O 0.2-2.5%.This activator is a kind of nontoxic cheap mineral matter.
The invention is characterized in that it is that flyash, gypsum (are pressed CaSO
4Meter) or have mixed by a certain percentage the forming of flyash, lime of gypsum composition, the flyash that wherein has the gypsum composition is by CaSO
4After calculating the gypsum composition, all the other are by flyash.The present invention does not need carrier substrates such as active carbon, and it is especially convenient to make.Use this deodorizing desiccant, can adsorb to fall between refrigerator, animal feeding effectively, the foul smell of pet such as cat and dog, and keep its space drying.
In order more effectively to bring into play the effect of above-mentioned flyash, gypsum, lime and activator, preferably its ratio of component is set at: flyash is the 45-75 weight portion, and gypsum is pressed CaSO
4Calculating is the 18-53 weight portion, and lime is the scope of 2-7 weight portion.If exceed this scope, effect separately is insufficient and can not fully adsorb foul smell, is difficult to the deodorizing dry effect that reaches satisfied.The used composition of the present invention must contain above 3 kinds of compositions, as required, also can add an amount of activator, but its consumption preferably is limited in 0.1 ‰ of deodorizing desiccant total amount-0.4 ‰ under the effect of not diluting above 3 kinds of compositions, is more preferably about 0.25 ‰ of total amount.
The present invention makes and to be characterised in that, raw material is mixed according to the above ratio, the water that per 100 parts of these mixtures (dry weight) add 30-45 part again, mixed evenly after, making diameter through make-up machine is that 3-10mm, length are the column of 5-30mm, back drying forms product.
The present invention can also directly utilize the dry flue gas desulphurization end product of coal-burning power plant.Power plant uses the desulfurizing agent of flyash as Main Ingredients and Appearance, with the self-produced flying dust of power plant, lime-ash after adding a certain proportion of lime and using, it is mixed to add water, make desulfurizing agent through kneading, granulating and forming, steam activation (100-150 ℃), drying, sorbent particle is directly by SO in desulfuration absorber and the flue gas
2Physical Absorption and chemical reaction directly take place, finally obtain the dry flue gas desulphurization end product, removing a part returns and does the desulfurizing agent raw material, all the other a large amount of dry flue gas desulphurization end products, add 0.1 ‰ of total amount-0.4 ‰ activator as required, promptly become deodorizing desiccant of the present invention through moulding, packing.
The active carbon goods of the deodorizing effect of low-cost deodorizing desiccant of the present invention and current market sale are suitable, but processing cost can be much lower, and processing technology is also very simple, adds micro-activator in the deodorizing desiccant, can when improving adsorption capacity, further strengthen the chemical deodorizing function.This product can be the end product of coal-burning power plant's dry flue gas desulphurization, also can utilize flyash processing to obtain, and after using, can reclaim this product as flowers and trees cultivation soil or farmland modifying agent, to increase fertility, improve soil texture, low-cost deodorizing desiccant promptly of the present invention has the secondary commercial value.
