Description
?
Technical field
The present invention relates to adhesive field, be specifically related to a kind of tackiness agent for the production of granular ammonium sulfate.
Background technology
Ammonium sulfate is the industrial raw material that is widely used in the industries such as chemical industry, dyeing and weaving, medicine, leather.In use there are many shortcomings in crystal ammonium sulfate as fertilizer sources: easily caking, poor fluidity, be difficult to realize mechanized application, and in application, easily form dust and run off.Granular ammonium sulfate good physical performance, does not play dirt, long-term storage prevented from caking, good fluidity during handling, easy spreading during fertilising, and can realize aircraft and broadcast fertilizer, reduce the loss, also can play slow releasing function simultaneously, the utilization ratio that improves fertilizer, is more and more subject to the especially welcome of foreign market of market.
Subordinate's Wengfu phosphate fertilizer plant of Wengfu Group Co., Ltd. and developed granular ammonium sulfate granulation novel process for 2009, has filled up a blank of domestic correlation technique.Granular ammonium sulfate product Han Dan Liang≤19.5 that Wengfu group produces for a long time, ton products with adhesive agent cost is about 150 yuan, effort through Wengfu phosphate fertilizer plant correlation technique, producers, develop a kind of new type bonding agent, guaranteeing under the prerequisite of granular ammonium sulfate product outer quality, ton products with adhesive agent cost drops to 50 yuan, and product per ton is saved 100 yuan, has created good economic benefit.
Summary of the invention
The object of the invention is provides a kind of new particulate ammonium sulfate production to use tackiness agent based on the market requirement.When guaranteeing product outer quality, granular ammonium sulfate product ton cost is declined 100 yuan/ton.
A kind of tackiness agent for the production of granular ammonium sulfate of the present invention, the main component of its tackiness agent is: Tai-Ace S 150, calcium carbonate, monoammonium phosphate; The mass percent of each composition of tackiness agent: calcium carbonate 10%～15%, Tai-Ace S 150 70%～75%, monoammonium phosphate 5%～10%.
Above-mentioned tackiness agent is when for the production of granular ammonium sulfate product, and effective proportioning of ammonium sulfate slurry and tackiness agent is for seeing the following form
Granular ammonium sulfate slurrying proportioning table:
| Sequence number | Title | Specification | Pure amount (kg) |
| 1 | Tackiness agent | Mixture | 50? |
| 2 | Ammonium sulfate slurry | 20.7-0-22.3 | 1000? |
| Add up to | ? | ? | 1050 |
This tackiness agent effectively utilizes the viscosity of material and the balling ratio that reaction heat improves product, during normal production, do not need to use steam or water to help granulation, reduced baked strength, can reduce costs, improve output, lower coal consumption, simultaneously can be according to market need to solve the even blending problem of available nutrient.
Above-mentioned tackiness agent in use, the ammonium sulfate slurry that upstream device is produced is mixed by a certain percentage with tackiness agent, send into granulation/drying machine spray granulating, work in-process obtain qualified 2mm-4mm product particle after broken, screening, washing, add as required tinting material, coating agent obtains granular ammonium sulfate product.
In aforesaid method, described in produce the ammoniumsulphate soln that raw material that granular ammonium sulfate product uses is phosphogypsum ammonium sulfate production processed, density: 1.24 g/ml-1.26g/ml, water ratio: 50%～58% N content: 20.5%-21.0%; In new type bonding agent, Tai-Ace S 150 is common industrial aluminum sulphate, and monoammonium phosphate is common fertilizer grade monoammonium phosphate, and calcium carbonate is upstream device byproduct (calcium carbonate content: 60%; Moisture content: 15%-20%).
Method provided by the invention has following advantage:
(1) the granular ammonium sulfate product that uses new type bonding agent to produce, is guaranteeing under the prerequisite of product outer quality, nitrogen content is guaranteed more than 19.5%, 100 yuan of ton cost decreases, remarkable in economical benefits;
(2) flow process that the device that this patent production method adopts and flow process are existing maturation, changes littlely, has reduced the risk of investing.
Embodiment
Be implemented in being mixed in groove of a belt stirrer, add ammonium sulfate slurry and tackiness agent simultaneously, density 1.24 g/ml-1.26g/ml of ammonium sulfate slurry, the ammonium sulfate slurry and the tackiness agent that enter the groove that is mixed carry out accurate proportioning metering.Preliminary mixed material pulp pumping to slurry circulation system is further mixed, and suitably heats slurry temperature is risen to 85 ℃-100 ℃.The slip preparing is sent into granulation/drying machine spray granulating
andthe high-temperature flue gas of approximately 550 ℃-600 ℃ dry, dry thermal source adopts coal-fired fluidizing furnace to produce.High-temperature gas is to whitewashing slip fluidized drying, the work in-process that obtain after dry are delivered to work in-process by bucket elevator and are sieved, after screening, 2mm-4mm particle enters the cooling and parcel of cooling cylinder and obtains product, >4mm particle after crusher in crushing with screening out 1mm-2mm particle as returning charge, return to granulation/drying machine.Dried tail gas is sent into Venturi scrubber scrubbing dust collection by exhaust fan through whirlwind depositing dust, and it is emptying that dedusting gas up to standard passes through aiutage.
Wengfu phosphate fertilizer plant of Wengfu Group Co., Ltd. is used the inventive method, utilize the granular ammonium device of a set of 200kt/a that the ammonium sulfate slurry of phosphogypsum ammonium sulfate production processed and phosphor ammonium slurry are produced to granular ammonium sulfate after proportioning, granulating and drying, fragmentation, screening, washing, painted parcel, formed the granular ammonium sulfate production throughput of 100kt/a at present.
