ELECTROSTATIC PARTICLE COLLECTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240024897 titled 'ELECTROSTATIC PARTICLE COLLECTOR

Simplified Explanation

The abstract describes an electrostatic precipitator (ESP) particle collector for collecting particles in a gas stream. It consists of an inlet section, a collector section, and an electrode arrangement. The inlet section includes a flow tube with a gas flow channel bounded by a guide wall. The collector section has a housing and a collector plate with a particle collection surface. The electrode arrangement includes a base electrode positioned below the collection surface and a counter-base electrode positioned above it to generate an electrical field for precipitating particles on the surface. The electric field has a range of 0.1 kv per mm to 1.5 kv per mm, with an absolute voltage on any electrode less than 10 kv. The ratio of the inlet radius to the separation distance is in the range of 0.8 to 1.2.

• The ESP particle collector is designed to collect particles in a gas stream for optical analysis.
• It includes an inlet section with a flow tube and a guide wall, and a collector section with a housing and a collector plate.
