Abstract

The invention discloses a laboratory urea hydrolysis reaction device. The device comprises a hydrolysis reactor. A heating furnace wraps the lower part and the periphery of the hydrolysis reactor. Theheating furnace utilizes an electric heating mode. The heating furnace cooperates with the hydrolysis reactor. The heating furnace is supported through support legs. The heating furnace is connectedto a controller with a temperature sensor through an electric wire. The controller is used for controlling the temperature in the controller and heating voltage. The upper part of the reactor is provided with a urea solution inlet and a reaction product outlet. The electric heating mode provides heat needed by the urea hydrolysis. The device has a simple structure and a large heating surface area,realizes uniform heating and has small reaction temperature errors and is suitable for laboratory research on urea hydrolysis.

Description

technical field [0001] The invention relates to a laboratory urea hydrolysis reaction device, in particular to a laboratory urea hydrolysis reaction device with a temperature control function. Background technique [0002] Ammonia has a very wide range of applications in industry. In industrial production, there are three sources of ammonia gas: liquid ammonia, ammonia water and urea, but liquid ammonia and ammonia water are hazardous chemicals. Therefore, considering safety and economy, urea is generally selected as the source of ammonia gas in industrial production. source. Urea can produce ammonia through pyrolysis and hydrolysis. Compared with pyrolysis, urea hydrolysis is safer and more controllable, and it also has more advantages in terms of economy. The urea hydrolysis process is that the urea solution generates ammonia and carbon dioxide under certain temperature and pressure conditions. [0003] At present, there are many related studies on urea hydrolysis, and ...
