摘要： 【課題】本発明は、帯電水粒子を用いた粉塵除去方法に関し、従来の粉塵除去方法では、事前に除塵対象の粉塵に係る正・負電荷の判別と電荷量とを計測していないので、能率的な除塵ができていないことができないことが課題であって、それを解決することである。 【解決手段】帯電水粒子9と粉塵9aと互いに電気的に吸引させて、前記粉塵9aを前記帯電水粒子9とともに除去する粉塵除去方法において、前記粉塵9aの正・負電荷のいずれであるかを正・負電荷判別手段によって判別し、前記判別された粉塵9aの電荷と反対の電荷を帯電手段11によって帯電された前記帯電水粒子9によって前記粉塵9aを除去する、帯電水粒子を用いた粉塵除去方法とする。 【選択図】図1

摘要： PROBLEM TO BE SOLVED: To simply and easily perform the inspection or calibration of a pressure detecting portion arranged in an automatic valve.
SOLUTION: In performing the inspection, water supply pressure detected by a master pressure sensor is measured as reference span pressure, and also measurement is performed concerning zero-point pressure to be secondary side open pressure detected by an automatic pressure sensor 52 at a first position of a remote three-way changeover valve 50 and concerning span pressure detected by the automatic valve pressure sensor 52 by introducing the water supply pressure to the second position of the remote three-way changeover valve 50 by changing-over. The state of the automatic valve pressure sensor 52 is determined based on the respective measurement values. Besides, a zero-point correction constant and a span correction coefficient are derived, which calibrate the zero point and span of the automatic valve pressure sensor 52 into the zero point and span of the master pressure sensor. After the calibration is terminated, the pressure detected by the automatic valve pressure sensor 52 is corrected based on the zero point correction constant and the span correction coefficient.
