Abstract

The invention relates to the chemical field and particularly relates to an embraced-type heating small urea hydrolysis reaction device and a hydrolysis method thereof. The embraced-type heating small urea hydrolysis reaction device comprises a reactor, wherein a layer of heating sleeves is embraced below the reactor; a steam heating way or electric heating way is adopted for the heating sleeves; the heating sleeves are engaged with a reactor; the reactor is supported by supporting legs; a reaction product outlet is formed in the upper part of the reactor; a urea liquor feeding hole and a drain outlet are formed in the bottom of the reactor; the feeding hole and the drain outlet penetrate through the bottom of the reactor and the heating sleeves. Heat needed for urea hydrolysis reaction is provided by virtue of the steam heating way or the electric heating way; the interior of a reactor barrel body is divided into a lower liquid-phase space and an upper gas-phase space. The embraced type heating small urea hydrolysis reaction device disclosed by the invention not only has a simple structure, but also has the characteristics of being great in heating surface area, quick in heating speed, uniform in heating, small in reaction temperature difference, and the like, and therefore, the embraced-type heating small urea hydrolysis reaction device is more conductive to preventing occurrence of equipment material corrosion and chemical side reaction.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an enveloping heating small-scale urea hydrolysis reaction device and a hydrolysis method. Background technique [0002] In industrial production, ammonia is used in many occasions. However, liquid ammonia is a hazardous chemical, so the country strictly controls the storage, use and transportation of liquid ammonia. [0003] Urea is a white crystalline granule, which does not belong to the category of hazardous chemicals. It is convenient for storage and transportation, and will not cause safety hazards due to leakage. Under certain pressure and temperature conditions, urea solution will be hydrolyzed to generate ammonia and carbon dioxide. [0004] At present, the existing urea hydrolysis reactors in the industry are all supporting equipment for large-scale production, and have the characteristics of large-scale. As the country's environmental protection requirements continu...
