Abstract
The utility model relates to a gas-liquid quick-reacting apparatus for polyiron production, which comprises a water jet pump (1), an oxygen cabinet (5) and a centrifugal pump (7), a reaction vessel (3), an oxygen conveying pipe (4) and a catalyst-adding opening (6). The utility model can oxidise Ferrous sulfate heptahydrate and sulfuric acid liquid with certain proportion into polyiron through the catalyzing function under normal temperature and normal pressure, and the reaction time is similar to the previous high temperature and high pressure reaction. The catalyst dosage is reduced to about 30 % when the utility model is used. At present, the utility model is used for producing thousands of tons of polyiron.
Description
A kind of gas-liquid quick reaction device of producing poly-iron, the utility model is specially adapted to the production of bodied ferric sulfate.
Bodied ferric sulfate (being called for short poly-iron) is a kind of more novel flocculation agent.Be applicable to the water purification agent of doing industrial water stop and waterworks, also can be used as sewage disposal etc.Poly-iron is raw material with ferrous sulfate, sulfuric acid, generates through catalyzed oxidation in reactor, and its reaction formula is:
2FeSO
4+ (1-(n)/2) H
2SO
4+ 1/2 O
2(NOx)/(catalysis)
Fe（OH）n（SO
4）3－ (n)/2 ＋（1－n）H
2O
NOx has participated in reaction as catalyzer in the formula, 0＜n＜1.Therefore in poly-iron production, oxygen to be fed the reactor that stock liquid is housed, add catalyzer then, make the ferrous sulfate catalyzed oxidation in the stock liquid.
Before the utility model, in reactor, mechanical stirring device is housed so that feed liquid and oxygen can hybrid reactions, but mechanical stirring device can not make fully feed liquid mix with oxygen, so just need heat, pressurize to add fast response.
The purpose of this utility model is exactly in order to develop a kind of gas-liquid reaction apparatus that can produce poly-iron under normal temperature, normal pressure, also can to make the abundant short mix catalytic oxidation reaction device of feed liquid and oxygen.
Measure of the present utility model be adopt the water jet pump of market supply with feed liquid in reaction process constantly cyclic spray by the stock liquid of impeller pump suction, the feed liquid that has atomized in injection is mixed, to reach the purpose that generates poly-iron under normal temperature, the normal pressure fast rapidly with oxygen.
Now in conjunction with the accompanying drawings the utility model is illustrated.
Fig. 1 is the utility model synoptic diagram, and 1 is squirt pump among the figure, and 2 for spraying into the stock liquid of reactor by water jet pump, and 3 is reactor, and 4 is oxygen conveying pipe, and 5 is the oxygen cabinet, and 6 for catalyzer adds inlet, and 7 is acid redidting centrifugal pump.
Characteristics of the present utility model are, it is except including reactor (3), oxygen conveying pipe (4), catalyzer adds inlet (6) in addition, also include water jet pump (1), oxygen cabinet (5) and acid redidting centrifugal pump (7), said impeller pump (7) is communicated with the bottom of reactor (3), and impeller pump (7) is connected with water jet pump (3).
When reaction, a certain proportion of ferrous sulfate and sulfuric acid stock liquid and catalyzer are constantly extracted out by impeller pump (7) circulation together, and the stock liquid that has atomized by water jet pump (1) ejection, the stock liquid that water jet pump (1) directly will atomize sprays into reactor (3), oxygen from oxygen cabinet (5) enters reactor (3) by oxygen transfer lime (4), under the effect of catalyzer fully, apace with the stock liquid hybrid reaction that has atomized, thereby under normal temperature, normal pressure, produce satisfactory poly-iron product.Oxygen is sent into oxygen conveying pipe (4) from source of oxygen again by oxygen cabinet (5) in the utility model, but not directly sends into oxygen conveying pipe (4) from source of oxygen as in the past, and the effect of oxygen cabinet (5) is in order to make oxygen decompression and voltage stabilizing.
Adopt the utility model to produce ton surplus the Polyferric Sulfate ten thousand that conforms with chemical industry standard, compare with in the past high temperature, the production of high pressure Polyferric Sulfate, under the prerequisite of equal volume reaction pot (3), close with in the past of required reaction time of the utility model, and the use amount of catalyst obviously reduces, and reduces about 30% than in the past approximately. As being 1.5 meters when the volume of reaction pot3The time, adopt the utility model, its reaction time is≤2 hours, and adopts HTHP production also to need about 2 hours.
