Abstract
A kind of disclosure of the invention sour method composite fertilizer tubular reactor, with ammonia-feeding pipe, sulfuric acid inlet pipe, three-way pipe, elbow, atomizer, due to installing ammonia-feeding pipe with one heart using perforate on the left of three-way pipe, sulfuric acid inlet pipe is installed in the perforate of three-way pipe top with one heart, sulfuric acid inlet pipe insertion three-way pipe right part is arranged concentrically with ammonia-feeding pipe, connecting bend on the right side of three-way pipe, elbow is connected with atomizer, ammonia spout is uniformly arranged on the portion tube wall of ammonia-feeding pipe insertion three-way pipe, sulfuric acid spout is uniformly arranged in the right part tube wall around of sulfuric acid inlet pipe insertion three-way pipe, the partial-length of ammonia-feeding pipe insertion three-way pipe is less than the structure of the part of insertion three-way pipe on the right side of sulfuric acid inlet pipe, contact area increases when ammonia reacts with dilution heat of sulfuric acid, the two hybrid reaction is more abundant, produce heat more, composite fertilizer's better quality of production.
Description
Technical field
The present invention relates to a kind of composite heat transfer mixing reactor, a kind of sour method composite fertilizer pipe reaction is directly related to
Device.
Background technology
In current compound fertilizer production technology, sour method composite heat transfer occupies critically important status, sour method composite fertilizer profit
The heat that sulfate of ammoniac and course of reaction produce is produced after being reacted with ammonia and dilute sulfuric acid and produces composite fertilizer, compound fertilizer granules are uniform,
Smooth, quality is good, deep to be trusted by vast farmerses friend, and traditional propylhomoserin mixing tubular reactor is mixed not due to ammonia with sulfuric acid
Uniformly, cause its reaction effect poor, heat production effect is poor, seeking one kind can be such that ammonia is answered with the well-mixed sour method of dilute sulfuric acid
Hefei tubular reactor is very necessary.
The content of the invention
During making sour method composite heat transfer it is an object of the present invention to provide one kind, ammonia and the well-mixed pipe of dilute sulfuric acid
Formula reactor.
The object of the present invention is achieved like this：A kind of sour method composite fertilizer tubular reactor, enters with ammonia-feeding pipe, sulfuric acid
Ammonia-feeding pipe is installed in perforate with one heart on the left of pipe, three-way pipe, elbow, atomizer, three-way pipe, and sulphur is installed in the perforate of three-way pipe top with one heart
Sour inlet pipe, sulfuric acid inlet pipe insertion three-way pipe right part is arranged concentrically with ammonia-feeding pipe, connecting bend on the right side of three-way pipe, elbow and mist
Change and ammonia spout, the insertion threeway of sulfuric acid inlet pipe are uniformly arranged on shower nozzle connection, the portion tube wall of ammonia-feeding pipe insertion three-way pipe
Sulfuric acid spout is uniformly arranged in the right part tube wall around of pipe, the partial-length of ammonia-feeding pipe insertion three-way pipe is less than sulfuric acid inlet pipe
The part of three-way pipe is inserted on right side.
Because the present invention uses perforate on the left of three-way pipe to install ammonia-feeding pipe with one heart, sulfuric acid is installed in the perforate of three-way pipe top with one heart
Inlet pipe, sulfuric acid inlet pipe insertion three-way pipe right part is arranged concentrically with ammonia-feeding pipe, connecting bend on the right side of three-way pipe, elbow and atomization
Shower nozzle is connected, and ammonia spout, sulfuric acid inlet pipe insertion three-way pipe are uniformly arranged on the portion tube wall of ammonia-feeding pipe insertion three-way pipe
Right part tube wall around on be uniformly arranged sulfuric acid spout, it is right that the partial-length of ammonia-feeding pipe insertion three-way pipe is less than sulfuric acid inlet pipe
The structure of the part of side insertion three-way pipe, ammonia enters ammonia inlet pipe, uniformly sprayed in ammonia inlet pipe tube wall around, in ammonia
Sulfuric acid spout is set in the sulfuric acid inlet pipe that gas inlet pipe external concentric is set, sulfuric acid inlet pipe tube wall around, and dilute sulfuric acid is by sulfuric acid inlet pipe
On sulfuric acid spout uniformly spray, with ammonia be sufficiently mixed reaction production sulfate of ammoniac, due to entering pipeline in ammonia inlet pipe, sulfuric acid
Uniform pore openings on tube wall, increase the contact area of ammonia and dilution heat of sulfuric acid, and the two hybrid reaction is more abundant, produce heat
It is more, composite fertilizer's better quality of production.
Brief description of the drawings：Accompanying drawing 1 shows a kind of structural representation of sour method composite fertilizer tubular reactor of the invention, below
1 it is described further with reference to the accompanying drawings.
Embodiment：
A kind of sour method composite fertilizer tubular reactor, with ammonia-feeding pipe 1, sulfuric acid inlet pipe 2, three-way pipe 3, elbow 4, atomizer 5,
Ammonia-feeding pipe 1 is installed in the left side perforate of three-way pipe 3 with one heart, and sulfuric acid inlet pipe 2 is installed in the top perforate of three-way pipe 3 with one heart, and sulfuric acid inlet pipe 2 is inserted
The right part of three-way pipe 3 is arranged concentrically with ammonia-feeding pipe 1, and the right side connecting bend 4 of three-way pipe 3, elbow 4 is connected with atomizer 5, entered
Ammonia spout is uniformly arranged on the portion tube wall of the insertion three-way pipe 3 of ammonia pipe 1, sulfuric acid inlet pipe 2 inserts the right side of three-way pipe 3
Sulfuric acid spout is uniformly arranged in point tube wall around, the partial-length of the insertion three-way pipe 3 of ammonia-feeding pipe 1 is less than the right side of sulfuric acid inlet pipe 2 and inserted
Enter the part of three-way pipe 3.
Operation principle：Ammonia enters ammonia inlet pipe, is uniformly sprayed in ammonia inlet pipe tube wall around, and dilute sulfuric acid enters sulphur
Sour inlet pipe uniformly sprays in sulfuric acid spout and reacted with ammonia, and mixed liquor enters atomizer through elbow after reaction, by atomizer
Ejection is granulated.
