Description
Technical Field
The utility model relates to a phosphorus pentasulfide production technical field specifically is a reaction unit of phosphorus pentasulfide of production.
Background
The production of phosphorus pentasulfide requires that sulfur and yellow phosphorus are firstly melted into liquid, then the liquid is mixed in a reaction kettle to generate chemical reaction to generate phosphorus pentasulfide, the reaction requires that sulfur and phosphorus are added according to a certain proportion, a high-temperature and high-pressure environment is required in the reaction process, the phosphorus pentasulfide generated after the reaction is in the molten liquid state and needs to be cooled and solidified into a solid state, a factory for producing the product at present does not have a systematic reaction device, the adding proportion is inaccurate, and the cooling mode after the reaction is unreasonable.
Disclosure of Invention
The utility model aims at providing a producer who produces this product does not have systematic reaction unit at present, and reinforced proportion is inaccurate, and the unreasonable problem of cooling method provides a reaction unit of production phosphorus pentasulfide.
The utility model has the following concrete scheme: the utility model provides a reaction unit of production phosphorus pentasulfide, includes sulphur liquid measurement cauldron, phosphorus liquid measurement cauldron, reation kettle, cooling kettle, and agitator motor and tail gas pipe are equipped with to the reation kettle top, and the blowing pipe is equipped with to the reation kettle bottom, the blowing pipe is connected with cooling kettle's feed inlet, tail gas pipe outer end is connected with tail gas processing apparatus, agitator motor is equipped with to the cooling kettle top, sulphur liquid measurement cauldron and phosphorus liquid measurement cauldron's discharge gate respectively are provided with a conveying pipe of being connected with reation kettle, all is equipped with the control valve on two conveying pipes.
The volume ratio of the sulfur liquid metering kettle to the phosphorus liquid metering kettle is 2.3-2.7.
The control valve is a pneumatic membrane regulating valve.
The outside of the sulfur liquid metering kettle, the phosphorus liquid metering kettle and the two feeding pipes are all provided with a heat preservation layer.
The utility model discloses the theory of operation as follows: sulphur liquid and phosphorus liquid are carried in sulphur liquid measurement cauldron and the phosphorus liquid measurement cauldron respectively, carry out chemical reaction through the pneumatic film governing valve of conveying pipe separately and generate phosphorus pentasulfide in carrying the reation kettle in proportion, liquid phosphorus pentasulfide flows into the cooling kettle from reation kettle's discharge gate, make it cool down to closing on the melting point by a wide margin through stirring and cooling, then in the discharge gate outflow of cooling kettle sent into the film-making device, the poisonous tail gas that produces in the reation kettle flows into in the tail gas processing apparatus through the tail gas duct.
Compared with the prior art, the utility model has the following advantages: the sulfur and the phosphorus are conveyed to the reaction kettle in proportion through the two metering kettles and the pneumatic film regulating valve, so that the proportion is more accurate; after the reaction, the liquid phosphorus pentasulfide is stirred and cooled by a cooling kettle to be greatly cooled, the cooling speed is high, and the production efficiency is improved.
