Abstract

The invention discloses sulfamic acid production equipment, and the equipment comprises a reaction kettle; a feeding port is formed in the top of the reaction kettle, a feeding pipe used for adding urea into the reaction kettle is inserted into the feeding port, a main shaft penetrates through the top of the reaction kettle, and the end, located in the reaction kettle, of the main shaft is connected with a stirring paddle; the other end of the main shaft is connected with a driving device used for driving the main shaft to rotate, the main shaft is connected with a material scattering disc, the material scattering disc is located in the reaction kettle, and a plurality of material scattering holes are formed in the material scattering disc. The invention further discloses a synthesis process for preparing sulfamic acid by adopting the sulfamic acid production equipment. The equipment has the advantages that the defect of non-uniform blanking of urea is overcome, so the reaction yield is improved.

Description

technical field [0001] The application relates to the field of sulfamic acid preparation, more specifically, it relates to a sulfamic acid production equipment and a sulfamic acid synthesis process. Background technique [0002] Sulfamic acid is a solid strong acid, which can be used as a bleaching agent in the paper industry, a foaming agent in the petroleum industry, an electroplating solution in the electroplating industry, a catalyst for chemical reactions, etc., and has a wide range of uses. [0003] Common sulfamic acid production processes include gas phase reaction method and urea method. The production process of sulfamic acid produced by urea method is simple, the reaction is easy to control, the raw materials and equipment are easy to solve, the waste water is also easy to handle, and the by-products can be effectively used. Therefore Wider application. [0004] The commonly used urea method to produce sulfamic acid is to sulfonate urea with oleum to prepare sulf...
