Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of preparation method of oxygenation agent, particularly utilize by-product bulky grain SODIUM PERCARBONATE to prepare oxygenation agent method.
Background technology
Preparation SODIUM PERCARBONATE preparation technology is divided into wet method and dry method substantially both at home and abroad at present.The most important effect of SODIUM PERCARBONATE is as washing assisant, and in order to guarantee effective compatibility of itself and other cleaning ingredients, the particle diameter that is exactly generally product to one of quality requirement of SODIUM PERCARBONATE product is controlled need be between 0.3-1.4mm.And in the production process of percarbonic acid acid sodium, dry, packing technology etc. all can occur that fluidized-bed layer lumps and produces oarse-grained by product, by product accounts for the 5-30% left and right of output.In by product particulate material, soda ash content is higher simultaneously, causes the active oxygen of product on the low side, cannot normally use.For this underproof by-product bulky grain SODIUM PERCARBONATE, generally can only carry out relevant treatment using it as waste product landfill or as salkali waste, make manufacturing cost significantly increase on the one hand, cause on the other hand the wasting of resources, be also unfavorable for environmental protection.
While, along with cultural technique, aquaculture cost improves constantly, is to pursue high yield, and the fishes and shrimps stocking rate of unit water surface area is also more and more higher.But highdensity cultivation easily causes cultivation pool oxygen content on the low side, particularly fishes and shrimps more concentrated region oxygen content in bottom, pool is lower, can cause fishes and shrimps death by suffocation, particularly in weather sultry period.Therefore cultivation can be carried out oxygenation to pool per family over a period to come.
Existing oxygenation agent, oxygenation agent as difunctional in hydrogen peroxide phosphoamide and carbonic acid amide high oxygen-enriching agent, in these oxygenation agents, all contain the harmful substances such as organic matter and heavy metal ion, and with certain penetrating odor, in aquaculture, oxygen inhalation health, can produce certain harm to human body, be unfavorable for people's health; Oxygenation agent stability is bad simultaneously, and when temperature is higher or period of storage is longer, oxygenation agent easily decomposes, and active oxygen amount decline in use, effect reduce.
Summary of the invention
For overcoming above-mentioned defect of the prior art, the invention provides a kind of method of utilizing by-product bulky grain SODIUM PERCARBONATE to prepare oxygenation agent.The oxygenation agent that employing is prepared by the method carries out oxygenation to breeding water body can reduce manufacturing cost, and reduces the pollution of existing oxygenation agent to water body, environment.
Utilize by-product bulky grain SODIUM PERCARBONATE to prepare a method for oxygenation agent, it is characterized in that, mainly comprise the following steps:
(A) in blender, add by-product bulky grain SODIUM PERCARBONATE and water, the addition of water is the 1%-3% of by-product bulky grain percarbonic acid mass percent, stirs 5-10 minute, with cracker, pulverizes; Described by-product bulky grain SODIUM PERCARBONATE is the irregular particle of active oxygen≤10%, particle size >=1.4mm;
(B) material after pulverizing enters spray hydrogen peroxide solution and stabilizing agent and adhesive in reactor, carries out granulation, dries, obtain oxygenation agent containing oxygen raw material SODIUM PERCARBONATE;
(C) ratio that is 99.0～99.9 ︰s 1～0.1 with releasing agent according to mass percent by step B gained SODIUM PERCARBONATE mixes, and on tablet press machine, compressing tablet makes oxygenation agent product.
Further, in steps A, blender is bipyramid or single cone ribbon mixer.
In step B, reactor is bipyramid ribbon mixer.The principle of bipyramid ribbon mixer is exactly to carry out granulation by means of the physical force of chemical reaction and bipyramid ribbon itself.Bipyramid ribbon mixer on the one hand can be even by mixing of materials well, and the product that its ribbon can react hydrogen peroxide with comminuting matter simultaneously wraps up effectively, prepares densification, uniform particle.
In step B, the mass concentration of hydrogen peroxide is 27.5%-70%.Hydrogen peroxide concentration also can regulate according to the active oxygen of product.
Stabilizing agent described in step B is one or more in HEDP, triethanolamine, magnesium sulfate, EDTA-2Na or ATMP, and the consumption of stabilizing agent is the 0.1%-2% of hydrogen peroxide mass fraction.
Adhesive described in step B is flower bulb alkali, the 0.1-1% that its consumption is comminuting matter.
The particle diameter of SODIUM PERCARBONATE described in step B is 0.3-1.4mm, and active oxygen is 12.0%-14.0%.
Releasing agent described in step C is dolomol, odium stearate or both mixtures.
The present invention utilizes by-product bulky grain SODIUM PERCARBONATE to prepare the method for oxygenation agent, by the substandard product in SODIUM PERCARBONATE production process (by-product bulky grain SODIUM PERCARBONATE) twice laid, oxygenation agent for the preparation of aquaculture, environmentally friendly, equipment investment is little, technique is simple, can prepare high-quality oxygenation agent product, Product Activity oxygen is high, heat endurance and wet good stability.
The present invention also provides the oxygenation agent being prepared from by said method.
The oxygenation agent of being prepared by SODIUM PERCARBONATE belongs to solid oxygen, and it is new and effective oxygenation agent, adopts special cylindrical particle design, can directly sink to pond bottom, after reacting with water, produce a large amount of oxygen, the water body dissolved oxygen that increases sharply, and can maintain for a long time the high dissolved oxygen in water; In producing the process of a large amount of small oxygen bubbles risings at the bottom of pond, can effectively be dissolved in water body, pond bottom He Zhong lower floor water body is carried out to oxygenation, reach the effect of " three-dimensional oxygenation ", really efficiently solve the problem of bottom anoxic.
Adopt this oxygenation agent to carry out oxygenation to breeding water body and can reduce manufacturing cost, and reduce the pollution of existing oxygenation agent to water body, environment.
