An Initial Exploration for Coulomb ESP
The coulomb ESP is fundamentally based on coulomb law which indicating the Coulomb force is inversely proportional to square of distance between two point charges. The sufficiently charged particles are all forced to dust-catching electrode by Coulomb force. Due to the velocity of wind around dust-catehing electrode trends to zero, dust cleaning is on off-line mode, the secondary fly-up can be overcome. According to practical application, the inlet concentration and outlet concentration are 30 g/Nm3 and <10 mg/Nm3 respectively for a 3.5 m long electrical field. The de-dust efficiency is up to 99.95％. Coulomb ESP is a high efficiency ESP. it can either enhances dust removal efficiency of ESP and decreases its weight to 1/2. According to practical application, the inlet concentration and outlet concentration are 30g/Nm3 and <10 mg/Nm3 respectively for a 3.5m long electrical field. The de-dust efficiency is up to 99.95 ％.
