Abstract

A sulfamic acid production line, the discharge port of the absorption tank (1) communicates with the feed port of the reaction tank (2) through a pipeline, and the discharge port of the reaction tank (2) communicates with the feed port of the absorption tank (3) through a pipeline The discharge port of the absorption tank (3) is connected with the suction filter tank (4) through the pipeline, and the discharge port of the dissolution pot (7) is connected with the feed port of the crystallization tank (9) through the pipeline (7-1) Communication, the outlet of the crystallization kettle (9) communicates with the inlet of the storage tank (10) through the pipeline, and the liquid outlet of the storage tank (10) communicates with the inlet of the buffer tank (11) through the pipeline (10-1), The liquid outlet of the buffer tank (11) communicates with the absorption tank (3) and the dissolution pot (7) respectively through pipelines. The invention has the advantages of simple working process, reasonable layout and stable and reliable production process of the sulfamic acid production line.

Description

technical field [0001] The invention relates to the field of fine chemical production, in particular to a sulfamic acid production line. Background technique [0002] At present, sulfamic acid is an important fine chemical product, widely used in a variety of industrial equipment and civil cleaning agents for metal and ceramics, petroleum and processing agents and cleaning agents, electroplating industrial agents, electrochemical polishing agents, asphalt emulsifiers , etchant, sulfonating agent for dye, medicine and pigment industry, dyeing agent, high-efficiency bleaching agent, flame retardant for fiber and paper, softener, resin cross-linking accelerator, herbicide, anti-drying agent and standard analytical reagent, etc. in various fields. Sulfamic acid can be made into extremely pure crystals that are stable at room temperature, and its aqueous solution has the same strong acidity as hydrochloric acid and sulfuric acid, also known as solid sulfuric acid. It is non-vol...
