Dust collector quality appraisal

dust collector is a common facility in boilers and industrial production. Its performance is usually evaluated by the amount of gas it can handle, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. In addition, the price, operation and maintenance costs, service life, and ease of operation and management of the dust collector are also important factors in evaluating its performance. There are many types of dust collectors, including bag dust collectors, electrostatic precipitators, cyclone dust collectors, and wet dust collectors. Each type of dust collector has its specific application scenarios and advantages.

A certain People's Court entrusted our company to appraise the quality of the dust collector involved in the case. An expert group was organized to conduct verification tests and comprehensive analysis based on the on-site inspection situation, laboratory physical evidence testing data and results, as well as relevant national standards and contract agreements. The experts made a comprehensive judgment that the filtration wind speed, dust removal efficiency and body air leakage rate of the dust collector involved did not meet the requirements of the "Contract" signed by both parties, and issued relevant physical evidence appraisal conclusions.
