The invention relates to a wet smoke self-temperature returning integrated smoke purification device and an application thereof. The device comprises a washing tower outer barrel, a smoke outlet, an absorbing liquid storing cavity and a gas inlet flue extending barrel, the smoke outlet is disposed at the top of the washing tower outer barrel, the absorbing liquid storing cavity is arranged below the washing tower outer barrel, the gas inlet flue extending barrel is connected with the side of the washing tower outer barrel and extends to inside of the washing tower outer barrel, a smoke inlet is arranged at the front end of the gas inlet flue extending barrel, a same-direction fair current spraying head and a reverse spraying head are arranged inside the gas inlet flue extending barrel, directions of liquid drop sprayed by the same-direction fair current spraying heads and smoke flowing direction are the same, vertical opposite spraying is formed with the reverse spraying heads, and foam induction rings are arranged between the same-direction fair current spraying heads and the reverse spraying heads. According to the wet smoke self-temperature returning integrated smoke purification device and the application thereof, multiple functions such as dust removing, desulfuration, defogging and smoke heat exchange are integrated, device structure is compact, the floor space is small, the problems of 'white smoke' or chimney rain of wet purification smoke can be remarkably eliminated, and influence of smoke discharging on surroundings or vision can be reduced.

The invention discloses a desulfurization and dust removal system for white smoke, which comprises an induced draft fan, a pretreatment chamber, a desulfurization and dust removal tower, a cooling and whitening chamber, a temperature-rising whitening chamber and a diffusion and whitening chamber connected in sequence. The top of the pretreatment chamber A first flue gas inlet is provided, and the induced air pipe of the induced draft fan communicates with the first flue gas inlet of the pretreatment chamber, and the pretreatment chamber is provided with a first spray device; the cooling The top of the de-whitening chamber is provided with a first partition, and the first partition divides the cooling and de-whitening chamber into successively connected spraying parts and demisting parts, and the top of the spraying part is provided with a second spraying part. A shower device, the demisting part is provided with a first demister. The white smoke elimination, desulfurization and dust removal system has good effects of white smoke elimination, desulfurization and dust removal, simple structure, convenient maintenance, low maintenance and operation costs, and solves the problems of serious white smoke emission and heavy smoke odor in the production of ceramic factories. question.

The invention relates to a double-membrane microelectrostatic precipitator, and relates to the field of special equipment for ultra-low-emission of particulate matter. A primary dust capturing section comprises a primary three-dimensional mass transfer liquid collecting disc, a primary membrane micro-electrocoagulation layer and a primary membrane distributor, and the primary membrane micro-electrocoagulation layer is arranged above the primary three-dimensional mass transfer liquid collecting disc; the primary membrane distributor is arranged above the primary membrane micro-electrocoagulation layer, and a secondary dust capturing section is arranged above the primary membrane distributor; the secondary dust capturing section comprises a secondary three-dimensional mass transfer liquid collecting disc, a secondary membrane micro-electrocoagulation layer and a secondary membrane distributor, and the secondary membrane micro-electrocoagulation layer is arranged above the secondary three-dimensional mass transfer liquid collecting disc; the secondary membrane distributor is arranged above the secondary membrane micro-electrocoagulation layer. By adopting a combination structure of special fillings and special three-dimensional mass transfer liquid collecting discs, and special spraying, and a simple combination with dehumidification equipment, the comprehensive environmental protection and emission reduction effects of gravity dust removal, inertial dust removal, cyclone dust removal and the like, which cannot be achieved by the traditional dust removal process, can be achieved.

The invention relates to a treatment method for flue gas and flue gas desulfurization wastewater. In the flue gas / desulfurization wastewater heat exchanger, the flue gas is used to exchange heat for the desulfurization wastewater, and a nozzle is set at the outlet of the flue gas to spray NaOH solution to make the flue gas At this time, the flue gas enters the bag filter to remove dust and sulfate / sulfuric acid droplets, and then enters the desulfurization tower; desulfurization purification and heating are carried out in the desulfurization tower, and the waste water at the bottom of the tower is used as The absorption liquid is circulated, and the others enter the plate heat exchanger in the form of desulfurization wastewater; the plate heat exchanger uses the steam condensed water generated by the heating coil in the exhaust cylinder to preheat the desulfurization wastewater, and after preheating, the wastewater enters the flue gas / desulfurization wastewater exchange heater. On the basis of making full use of the waste heat of the flue gas, the present invention realizes the dual purpose of purifying the flue gas to meet the emission requirements and zero discharge of flue gas desulfurization waste liquid, and simultaneously eliminates "white smoke" and "blue smoke", and reduces the cost of flue gas desulfurization. and the comprehensive treatment cost of desulfurization waste liquid.
