Abstract

The invention discloses a reactor for hydrolysis of urea. The reactor comprises a main reaction container, a main heater, an auxiliary heater and a gas collector; the main reaction container is provided with an internal separator plate which separates the main reaction container into a main heating chamber and an auxiliary heating chamber, the main heating chamber and the auxiliary heating chamberare respectively provided with a urea liquid inlet and a liquid outlet, the bottom parts of the main heating chamber and the auxiliary heating chamber are not communicated, and the top parts of the main heating chamber and the auxiliary heating chamber are communicated. The reactor is provided with designs of the unique heater and the gas collector, size of the reactor can be flexibly selected according to concrete hydrolysis demands, the reactor is good for saving energy, gas-liquid separation effects of gas collection are good, urea hydrolysis is more sufficient, hydrolysis efficiency is high, and the reactor is suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of urea hydrolysis mechanical equipment, in particular to a urea hydrolysis reactor with novel structural design, sufficient urea hydrolysis and good gas drying effect. Background technique [0002] At present, the factors affecting the hydrolysis of urea include temperature, the initial concentration of water in the solution, the content of urea, the content of ammonia and carbon dioxide in the solution, and catalysts. At a higher reaction temperature, if a sufficiently long reaction time can be ensured, and the ammonia and carbon dioxide produced by hydrolysis are removed in time, the urea in the solution can basically be completely hydrolyzed. At present, the method of urea hydrolysis is often used to produce ammonia, and the urea ammonia production process includes urea hydrolysis and urea pyrolysis. The urea hydrolysis and urea pyrolysis processes have different chemical processes due to different temp...
