A heat pipe and synergistic desulfurization wastewater treatment water mist charged coupled particle modified and synergistic electrostatic precipitator system

Abstract

The present invention provides a water mist charging coupled particle modified and synergistic electrostatic precipitator system for heat pipes and its cooperative desulfurization wastewater treatment. The system includes a water mist charging device and an electrostatic precipitator. The water mist charging device is installed On the flue in front of the entrance of the electrostatic precipitator, the water mist charging device is connected to the desulfurization wastewater temporary storage pool, the water mist charging device is equipped with an atomizing nozzle, and a corona ring is installed downstream of the atomizing nozzle, and the corona ring is connected to a high voltage power supply . The invention provides a new heat pipe structure. At the same time, the invention obtains the mixed spray of desulfurization wastewater and particle modifier through the two-fluid atomizing nozzle, and charges the charging ring quickly, which can not only effectively treat the desulfurization wastewater, but also make the The fine particles are fully agglomerated to improve the removal efficiency of particles; at the same time, the water mist charging device can be installed on the flue in front of the entrance of the electrostatic precipitator, which is flexible and convenient.

Description

technical field [0001] The invention relates to the fields of heat pipe waste heat recovery, flue gas dust removal and organic matter removal, in particular to a water mist charge coupling particle modification and synergistic electrostatic dust removal technology utilizing heat pipes to recover flue gas waste heat and cooperative desulfurization wastewater treatment. Background technique [0002] Heat pipe technology was developed in Los Alamos, USA in 1963. national laboratory A heat transfer method called a "heat pipe" invented by George Grover element , it makes full use of the principle of heat conduction and the rapid heat transfer properties of phase change media, and quickly transfers the heat of the heating object to the heat source through the heat pipe, and its thermal conductivity exceeds that of any known metal. Compared with the most commonly used shell-and-tube heat exchanger in coal-fired flue gas waste heat recovery, the heat pipe heat exchanger has the ad...

AI Technical Summary

Problems solved by technology

The conventional "three-box" process is difficult to remove Cl- in wastewater, which makes it difficult to recycle the treated wastewater. However, zero-discharge technologies for desulfurization wastewater such as membrane filtration and MVR have high investment and operation costs, which limits their practical application.
