Identification of evaporative crystallization equipment

evaporation and crystallization equipment is mainly used to evaporate and crystallize incompatible substances in the solution. The evaporation and crystallization equipment must have sufficient heat source to maintain the boiling of the solution and supplement the heat taken away by the vaporization of the solvent, so as to precipitate the substance from the solution in a crystalline state. Evaporation and crystallization equipment is often used in the evaporation, concentration and crystallization process of liquid materials in pharmaceutical, chemical, food, light industry and other industries and in the treatment of industrial wastewater such as high-salt wastewater and salt-containing wastewater generated by various industries.
Zhongke Testing and Appraisal Institute can provide evaporation crystallization equipment appraisal services and make accurate appraisals in terms of product design analysis, load analysis and product quality analysis.

A technology company purchased the MVR evaporation and crystallization treatment equipment for the high-salt wastewater involved in the case from a chemical company. During the test run, the compressor frequently failed and was still unable to operate normally after multiple repairs. Therefore, the technology company went to court.
Our company was entrusted by the court to undertake the quality analysis of the "evaporation crystallization equipment" involved in this case.
identification and analysis results: The
quality analysis expert group discussed and comprehensively technical analyzed the relevant information, on-site investigation and inspection, and inspection and testing data of the "evaporation crystallization equipment" involved in the case, and made the following quality analysis opinions:
The "evaporation crystallization equipment" equipment involved in the case did not meet the acceptance standards, and the design, manufacturing and installation were unqualified.
