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.

Abstract

The invention provides a heat pipe and a spray charging and particle modifying coupled synergistic electrostatic dust removing system assisting in desulfurization waste water treatment. The system comprises a water charging device and an electrostatic dust remover. The water charging device is installed on a flue on the front portion of an inlet of the electrostatic dust remover. The spray charging device is connected with a desulfurization waste water temporary storage pool and provided with an atomizing nozzle. A corona ring is installed at the downstream of the atomizing nozzle and connected with a high-voltage power supply. The novel heat pipe structure is provided, meanwhile, mixed spray of the desulfurization waste water and a particle modifier is obtained through the dual-fluid atomizing nozzle, quick charging is achieved through a charging ring, the desulfurization waste water can be effectively treated, fine particles can be fully agglomerated, and the particle removal efficiency is improved; and meanwhile, the spray charging device can be installed on the flue on the front portion of the inlet of the electrostatic dust remover, so that flexibility and convenience are achieved.

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...
