Problems solved by technology

The production process of massive crystalline ferric chloride belongs to intermittent production, which occupies a large production site and labor intensity in the process of cooling molding and packaging. The product produced by this method is a whole piece of dense solid product, and the dissolution rate is slow; centrifugal separation When producing powdery or granular crystalline ferric chloride, the crystallization ratio accounts for about 30% to 50% of the total amount of ferric chloride, the material utilization rate is low, the requirements for crystallization process control are high, and production control is difficult.

Abstract

The invention discloses a production method of flaky crystallized ferric chloride, which is used for producing the crystallized ferric chloride by a method of crystallizing a ferric chloride solutionon the surface of a low-temperature roller flaker by utilizing the characteristic that the ferric chloride solution with the concentration of 55-65% is changed into crystallized ferric chloride at thetemperature of 37 DEG C or below. According to the method, the problem that a ferric chloride concentrated solution is required to be controlled in the pre-crystallization process of a crystallization kettle during production of powdery or granular crystallized ferric chloride is avoided, and meanwhile, high-intensity labor existing in the production process of blocky ferric trichloride is also avoided. Through the method of producing the flaky crystallized ferric chloride product by directly cooling a ferric chloride concentrated solution on the surface of a roller, the utilization rate of materials is increased, the labor intensity and the production control difficulty are reduced, and the crystallized ferric chloride product convenient for customers to dissolve and use is prepared.

Description

technical field [0001] The method belongs to the field of crystalline ferric chloride production, and specifically relates to a method for freezing a ferric chloride solution through a flaking machine to obtain crystalline ferric chloride. Background technique [0002] The production of ferric chloride products from the iron-containing waste hydrochloric acid produced by hydrochloric acid pickling on the surface of steel is currently the most common treatment method for resource utilization of iron-containing waste hydrochloric acid. Crystallized ferric chloride is a solid form of ferric chloride , due to its high active ingredients, easy transportation and storage, etc., it has become a ferric chloride product that ferric chloride manufacturers are competing to produce. [0003] At present, the common production mode of crystalline ferric chloride is the massive crystalline ferric chloride produced by the ferric chloride concentrate freezing method, (such as Ding Decai's "P...
