Zhejiang Cement Group Company
Basic Customer Needs：
1、The evaluation of the pollutant treatment effect after the ultra-low emission transformation of enterprises requires professional guidance from unorganized emissions, organized emissions, clean transportation, and other aspects.
2、The client's "Emergency Emission Reduction Technical Guidelines for Key Industries in Heavily Polluted Weather (Revised in 2020)" (Environmental Office Atmospheric Letter [2020] No. 340) has applied for a rating of A, providing professional guidance on performance grading indicators, pollution control technology, emission limits, unorganized control requirements, monitoring and monitoring level, and environmental management level.
3、The "four no two direct" inspection method is becoming increasingly frequent, and it is necessary to investigate the installation and operation of automatic online monitoring equipment in accordance with relevant legal norms, identify potential problems or hidden dangers, sort out and analyze them, and propose suggestions and solutions to ensure the "truth, accuracy, and completeness" of online monitoring data, in order to self prove innocencee.
4、We need to strengthen our own level of supervision and management of online monitoring and third-party operation and testing units; Need professional training in online monitoring related knowledge.
Main Production Processes：
Raw material preparation, raw material grinding, clinker firing, cement grinding
The Governance Process Includes：
SNCR, SCR, wet desulfurization, Electrostatic precipitator, bag type dust removal, etc
CEMS System：
CEMS-1000
Customer Issues：
During on-site calibration of the CEMS system, there was a significant deviation in SO ₂；Long response time for full calibration；There are liquid droplets and ammonium salt crystals in the pipeline；The full calibration cannot be passed；Zero point offset during automatic calibration using air；Long term zero on-site SO ₂ data.1、Provide "online monitoring and precise management overall consulting" services for customers based on their needs; The content includes: full site inspection services, diagnostic services for key production processes' four simultaneities', third-party service supervision and assessment, customized professional knowledge training services; Serious issues such as debugging reports, acceptance reports, and measurement data anomalies were identified through investigation, and timely rectification suggestions were pointed out and proposed to prevent risks and hidden dangers.
2、Provide professional training on online monitoring level and third-party operation and testing units, and develop and improve supervision and assessment mechanisms. By reviewing the production process, pollution prevention and control technology, organized/unorganized, clean production, and environmental management level of the enterprise, rectification suggestions are proposed for the existing problems in the performance rating and ultra-low evaluation work of the enterprise, helping the enterprise to smoothly enjoy the dividends of environmental protection policies.
3、Survey the customer's on-site working conditions, customize the PreGASS-9500 in-situ pre-treatment system according to the on-site installation conditions, and connect it without changing the customer's original CEMS system. This effectively removes moisture and ammonia from the flue gas, prevents the loss of SO ₂ and ammonium salt crystallization, improves response speed, meets standard requirements, and solves customer problems.
Conduct full process calibration of the CEMS system on site, with a deviation of SO ₂<2.5%；Full calibration response time<120 seconds；There are no liquid droplets or ammonium salt crystals in the pipeline；
The entire calibration process passed smoothly;
On site SO ₂ data is stable and fluctuates with the process, with no zero display.
