Spray tower and electrostatic dust-removing, desulfurizing and denitrating device

Abstract

The invention relates to a spray tower electrostatic dusting removal desulphurization and denitration device, which mainly comprises a spray tower and an electrostatic processor, wherein the electrostatic processor comprises a humidity and temperature adjuster, an activation device and an ammonium salt collector; the humidity and temperature adjuster, the activation device and the ammonium salt collector are arranged in the same shell; and a humidifying temperature adjusting area of the humidity and temperature adjuster, an ammonification activating area of an ammonification activation device, an oxidation synthesizing area of an oxidation synthesizer, and an ammonium salt collecting area of the ammonium salt collector are arranged in the shell sequentially along the airflow direction. By adopting the structure, the spray tower is used to perform dust removal so that the flue dust content accords with the discharge requirement, and a wet dust removal process is used to humidify the flue gas so as to reduce the humidification amount for the subsequent process; the subsequent humidity and temperature adjuster, the activation device and the ammonium salt collector are combined together organically to save connecting pipelines between the devices so that the structure is more compact, the airtightness is improved, the ground is saved, and the maintenance is more convenient. The spray tower electrostatic dusting removal desulphurization and denitration device is mainly applied to the dusting removal, the desulphurization and the denitration of the flue gas.

Nanosecond pulse high-voltage power supply for activating water vapor and ammonia, pulse discharge plasma reactor for the reaction of activated water vapor and ammonia with sulfur dioxide and nitrogen oxides in flue gas, for collecting by-products The by-product collection device, the flue gas humidification and cooling tower are connected with the pulse electric plasma reactor and the by-product collection device in sequence, and the gas ammonia dosing devi...

AI Technical Summary

Problems solved by technology

Since the flue gas humidification and cooling tower is connected with the pulse discharge plasma reactor and the by-product collection device in turn through the flue gas pipeline, and because there is a spray tower before this device, the structure occupies a large area. There are problems such as large one-time investment and high energy consumption
