Description

Technical Field

[0001] The utility model relates to the technical field of urea hydrolysis, in particular to a urea hydrolysis decomposition device. Background Art

[0002] Urea hydrolysis refers to the process of converting urea into ammonia and carbon dioxide through a hydrolysis reaction. This reaction usually needs to be carried out at an appropriate temperature and pressure to achieve efficient product generation. Hydrolysis is usually one of the important steps for extracting ammonia from urea in industrial production. Urea hydrolysis produces ammonia, but ammonia contains water, which is inconvenient to remove, and the water contained in ammonia will affect the system.

[0003] A Chinese patent discloses a novel horizontal urea hydrolysis device (authorization announcement number CN211133964U). The patented technology mainly includes a horizontal reactor, a matching steam heating cylinder is fixedly sleeved on the outer side of the horizontal reactor, one end of the horizontal reactor extends to the outer side of the steam heating cylinder, and the end of the horizontal reactor is fixedly connected with a feed pipe, the bottom of the steam heating cylinder is fixedly connected with a support leg, and the bottom of the steam heating cylinder is fixedly connected with a steam inlet pipe, the top of the steam heating cylinder is fixedly connected with a pressure relief pipe, the top of the steam heating cylinder is fixedly connected with a reaction box, and a gas processing mechanism is installed in the reaction box, the reaction box is a hollow structure with an opening at the top, and a sealing cover is hingedly connected at the opening position, and the bottom of the reaction box is fixedly connected with an exhaust pipe.

[0004] However, there are still some shortcomings in this patent. This patent is convenient for fully absorbing and treating the carbon dioxide gas produced by urea hydrolysis, avoiding direct emission of carbon dioxide gas and exacerbating the greenhouse effect of the earth; however, urea hydrolysis will produce ammonia gas, which contains water, and the water is inconvenient to remove. At the same time, the water contained in the ammonia gas will affect the system. Therefore, those skilled in the art provide a urea hydrolysis and decomposition device to solve the problems raised in the above background technology. Utility Model Content
