Description
Technical field
The utility model relates to urotropine and middle-size and small-size Ammonia Production field, is specifically related to a kind of device of synthetic ammonia coproducing urotropine.
Background technology
Urotropine as the catalyzer of the solidifying agent of resin and plastics, aminoplastics and whipping agent, the promotor (vulkacit H) of the vulcanization of rubber, the sanforzing agent of textiles, is the raw material of organic synthesis mainly, in medicine industry, is widely used.
At present; The working method of urotropine mainly contains two kinds of liquid phase method and vapor phase processs, no matter be vapor phase process or liquid phase method, its production process must have gas ammonia to participate in reaction; Gas ammonia is from liquefied ammonia equipment for gasification in the urotropine technology; And consume a large amount of steam in the liquefied ammonia gasification, exist energy consumption high, the shortcoming that production cost is high.
At present, the recovery of gas ammonia is to pressurize after vaporizer-condenser is cooled to liquefied ammonia through ice maker in the production of synthetic ammonia, and the gas ammonia liquefaction process mainly leans on the ice maker operation, consume certain electric energy.
In order to solve in the existing urotropine production process in the liquefied ammonia gasification in the steam consumption height and production of synthetic ammonia the high problem of power consumption in the gas ammonia liquefaction process; Be necessary to develop a kind of combination preparing device; Cut down the consumption of energy reasonable energy utilization, the purpose that reduces production costs to reach.
Summary of the invention
The utility model is in order to solve in the urotropine production process in the liquefied ammonia gasification in the steam consumption height and production of synthetic ammonia the high problem of power consumption in the gas ammonia liquefaction process, and a kind of device of synthetic ammonia coproducing urotropine is provided.
The utility model is realized through following technical scheme:
A kind of device of synthetic ammonia coproducing urotropine; Comprise ammonia synthesis converter, ice maker system, coke filter, ammonia surge tank, ammoniation reactor, system formaldehyde system, cooling separator; Wherein ammonia synthesis converter is connected with coke filter with the ice maker system respectively through pipeline; Coke filter is connected with ammonia surge tank, ammoniation reactor, cooling separation respectively through pipeline, and described ammoniation reactor also is connected with system formaldehyde system.
During use; A gas ammonia part of coming out from ammonia synthesis converter in the synthetic ammonia workshop section is sent to coke filter through piping; A part liquefies through the ice maker system; The gas ammonia that is sent to coke filter gets into ammoniation reactor after through the ammonia surge tank, with formaldehyde hybrid reaction in reactor drum that system formaldehyde system generates, separates through cooling separation then.
The utility model is the test use of Pinglu company of the fertile industry of Yang Meifeng happiness (group) Ltd through Shanxi; The said firm has a cover year 1.5 ten thousand tons of vapor phase processs of design to produce the urotropine device; According to design, per hour produce 1.875 tons of urotropines (year was according to 8000 hours), urotropine consumption 0.6 ton of ammonia (design) per ton; This covering device of our company per hour can consume 1.125 tons of ammonia so; One ton of ammonia of the every recovery of synthesis ammonia system needs the cold of 500,000 kilocalories, adopts this method to produce tropine so, and synthesis ammonia system per hour can reduce the ice maker that refrigerating duty is 560,000 kilocalories.The ice maker necessary electromotor of so big refrigerating duty is 220KW, moves 8000 hours, 0.5 yuan of every degree electricity price lattice, and the synthesis ammonia system Spring Festival holidays are economized 880,000 yuan of the electricity charge so.
Produce 1.5 ten thousand tons of urotropine devices per year and per hour need 1.125 tons in liquefied ammonia; So many liquefied ammonia that gasifies needs 0.5611 ton of the saturation steam of 1.0MPa (becoming 80 ℃ hot water after the saturation steam cooling of 1.0MPa); 4888.8 tons of saturation steams that need 1.0MPa so year; The ton 1.0MPa of Pinglu company steam cost is 149 yuan at present, and year saving expense is 66.88 ten thousand yuan so.
In sum, energy-saving synthetic ammonia coproducing urotropine can be saved the electricity charge and the steam expense adds up to 154.8 ten thousand yuan every year.
The utility model is simple in structure, is easy to promote, and can significantly reduce manufacturing cost, cuts down the consumption of energy.
