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 ensure effective compatibility of itself and other cleaning ingredients, the size controlling being exactly generally product to one of quality requirement of SODIUM PERCARBONATE product need between 0.3-1.4mm.And in the production process of percarbonic acid acid sodium, drying, packing technology etc. all can occur fluidized-bed layer caking and produce oarse-grained by product, by product accounts for about the 5-30% of output.In byproduct particles material, soda 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 it can be used as waste product landfill or carry out relevant treatment as salkali waste, making manufacturing cost significantly increase on the one hand, causing the wasting of resources on the other hand, be also unfavorable for environmental protection.
Simultaneously along with cultural technique, the improving constantly of aquaculture cost, be pursue high yield, 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, and the region oxygen content that particularly bottom pool, fishes and shrimps are more concentrated is lower, can cause fishes and shrimps death by suffocation, particularly in the period that weather is sultry.Therefore cultivate and can carry out oxygenation to pool over a period to come per family.
Existing oxygenation agent, oxygenation agent as difunctional in hydrogen peroxide carbamide and carbonic acid amide high oxygen-enriching agent, all containing the harmful substance such as organic matter and heavy metal ion in these oxygenation agents, and with certain penetrating odor, certain harm can be produced to human body in aquaculture, oxygen inhalation health, be unfavorable for the health of people; 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, effect reduce in use.
Summary of the invention
For overcoming above-mentioned defect of the prior art, the invention provides a kind of method utilizing by-product bulky grain SODIUM PERCARBONATE to prepare oxygenation agent.Adopt the oxygenation agent prepared by the method 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.
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, pulverizes with cracker; 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) step B gained SODIUM PERCARBONATE mixed according to the ratio that mass percent is 99.0 ~ 99.9 ︰ 1 ~ 0.1 with releasing agent, on tablet press machine, compressing tablet obtains oxygenation agent product.
Further, in steps A, blender is bipyramid or singly bores 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 hydrogen peroxide and comminuting matter react can wrap up by its ribbon effectively simultaneously, 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 sodium silicate, and its consumption is the 0.1-1% of 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 substandard product (the by-product bulky grain SODIUM PERCARBONATE) twice laid in SODIUM PERCARBONATE production process, for the preparation of the oxygenation agent of aquaculture, environmentally friendly, equipment investment is little, technique is simple, can prepare the oxygenation agent product of high-quality, Product Activity oxygen is high, heat endurance and wet good stability.
Present invention also offers the oxygenation agent be prepared from by said method.
The oxygenation agent prepared by SODIUM PERCARBONATE belongs to solid oxygen, and it is new and effective oxygenation agent, adopts special cylindrical particle to design, directly can sink to pond bottom, produce a large amount of oxygen after reacting with water, increase sharply water body dissolved oxygen, and can maintain the high dissolved oxygen in water for a long time; Produce at the bottom of pond in the process of a large amount of small oxygen bubble rising, can effectively be dissolved in water body, oxygenation be carried out to pond bottom and middle lower floor water body, reaches 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.
