Electrostatic Precipitator Gravity Dust Discharge System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrostatic precipitation systems face issues with clogging and performance degradation due to the discharge of low-density, high-viscosity, and high-hygroscopicity dusts, which cause transfer failures and damage to facilities.
Innovation Solution
The electrostatic precipitation system includes an electrostatic precipitator, a main hopper, sub-hoppers, vertical ducts, and a water tank, where dusts are transferred by gravity through these components without a dust fall-hindering member, allowing them to fall into the water tank and be removed, ensuring continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dust transfer facilities (conveyors, rotary valves) are used to discharge collected dusts, then dust discharge function is provided, but clogging and facility damage occur due to high viscosity and hygroscopicity of dusts
Solution Approach 1:
The patent extracts the dust discharge function from conventional transfer facilities (conveyors, rotary valves) and implements a direct gravity-based discharge system where dusts fall directly from the hopper into the water tank, eliminating the harmful intermediate transfer components that cause clogging and damage
Solution Approach 2:
The patent introduces water as an intermediary medium in the dust discharge path. Dusts fall into the water tank where they are immediately contacted by water, preventing them from adhering to facility surfaces and enabling continuous operation without clogging
2Ease of operation
If steel structures and rotating parts are added to support dust transfer facilities, then dust discharge capability is improved, but wear and damage to rotating parts increases
Solution Approach 1:
The patent replaces the mechanical dust transfer system (conveyors, rotary valves with motors) with a gravity-based direct fall system. Dusts are discharged purely by gravity from the hopper bottom opening into the water tank, eliminating all rotating parts and mechanical drive components that suffer from wear and damage
Solution Approach 2:
The patent removes all rotating parts, motors, and complex mechanical transfer facilities from the dust discharge system, retaining only the essential gravity-based discharge function through a simple hopper opening
3Productivity
If dusts are transferred through conventional facilities, then dust discharge is achieved, but transfer failure occurs due to dust adhesion
Solution Approach 1:
Water serves as an intermediary medium that dusts contact immediately upon discharge. This water contact prevents adhesion to facility surfaces and ensures reliable, continuous dust discharge without transfer failures
Solution Approach 2:
The patent eliminates intermediate transfer facilities (ducts, conveyors, valves) that cause adhesion problems, allowing dusts to discharge directly into water where they are immediately wetted and prevented from sticking

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables reliable and normal operation of facilities by preventing clogging and damage from high-viscosity dusts, ensuring continuous operation of the electrostatic precipitation system.
Implementation Method 1
An electrostatic precipitator is a device that applies an electric field to dusts suspended in a gas, e.g., air and charge them, and cleans the gas by collecting particles contained in dusts with an electrostatic force
Implementation Method 2
a step (S20) of transferring by gravity, to a main hopper, the dusts separated in the step (S10); a step (S30) of transferring by gravity, to a plurality of sub-hoppers, the dusts transferred to the main hopper in the step (S20); a step (S40) of transferring by gravity, to a vertical duct, the dusts transferred to each of the sub-hoppers in the step (S30)
