GJSC系列不结露爬弧放电除尘技术在市政污水处理工程中应用新方法提升效率与效果
简介：本文介绍了GJSC系列不结露爬弧放电除尘技术在市政污水处理工程中应用的新方法，提升效率与效果。该技术采用定电位电解法，通过传感器在一定电位作用下，当被测气体通过传感器渗透膜进人电解槽时，发生电化学反应而产生电流，electric current signal size and the concentration of the gas to be measured are directly proportional. The advantages of this technology include high sensitivity, wide measurement range, low pre-processing requirements, and low cost.
The dust monitoring system uses an alternating current coupling principle, installation is convenient, maintenance volume is small. The flow rate uses a hot-type mass flow meter without reverse blowing. The system has functions such as automatic switching between monitoring and calibration, timely drainage of water accumulation, data transmission at regular intervals, remote maintenance, remote fault diagnosis and printing reports in the management center for curves charts daily report monthly report annual report.

3 units have been installed in Dalian Shandong Tianjin with good feedback from users on its friendly interface easy use high reliability easy maintenance extensibility strong features in real-time monitoring functionality through telephone network can view data at any time for certain pollution sources；Data Management Function can store each day's data into local database on site、remote reading storage into user database、curve charting query tool etcetera。
4 Remote Maintenance Capability allows online adjustment via software；
5 User Feedbacks & Issues：
Zhejiang Province Environmental Protection Bureau purchased our ZH—2521 Continuous Emission Monitoring System。
From operation status we consider that this system possesses intuitive interface、user-friendly operation、high reliability maintainability expandability strong points。
In particular instant continuous emission monitors provide hourly average values which are transmitted to central database automatically every hour so that these values are always up-to-date；Furthermore emissions limit exceedance alerts may be set remotely using password protected access thus ensuring quick response to potential violations。
