Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a zero-discharge filtering device for desulfurization wastewater. Background Art

[0002] Desulfurization wastewater is primarily discharged from the absorption tower during the wet flue gas desulfurization (limestone / gypsum process) process. Impurities in this wastewater primarily include suspended solids, supersaturated sulfites, sulfates, and heavy metals, many of which are Class I pollutants that require strict control under environmental standards. Filtration equipment is required to treat this desulfurization wastewater.

[0003] The zero-emission desulfurization wastewater devices currently on the market still have poor desulfurization wastewater treatment effects and cannot truly achieve zero emissions. They are also inefficient and difficult to operate. They do a poor job of concentrating desulfurization wastewater and cannot effectively concentrate and reduce the amount of desulfurization wastewater. This requires multiple filtrations to treat the desulfurization wastewater.

[0004] For example, a desulfurization wastewater filtration device disclosed in Chinese patent CN220345178U includes a water inlet hopper, a filter plate, a dirt collection hopper, a desulfurization wastewater filter tank, a scraper, and a spray hood. The bottom end of the desulfurization wastewater filter tank is provided with a second drainage head, the second drainage head is provided with a solenoid valve, a filter plate is provided at an upper position inside the desulfurization wastewater filter tank, a scraper controlled by a motor is provided on the top of the filter plate, and a detachable water inlet hopper is provided at the top middle of the desulfurization wastewater filter tank. The desulfurization wastewater filter tank of this utility model is provided with a water inlet hopper at the top, wastewater inlets are provided on both sides of the top of the water inlet hopper, wastewater is easily introduced through the wastewater inlet, and wastewater can be evenly diffused and discharged through the spray hood. A filter plate is provided at an upper position of the inner cavity of the desulfurization wastewater filter tank, through which filtration can be performed, and a scraper controlled by a motor is provided on the top of the filter plate, through which dirt on the filter plate can be cleaned.

[0005] When filtering desulfurization wastewater, the above-mentioned device uses stirring to perform preliminary filtration treatment. Most wastewater treatment methods use stirring. During stirring, the wastewater and impurities mixed in the wastewater will always be in a sealed container. After stirring, although most of the impurities will be deposited at the bottom of the sealed container, some impurities will still be free in the upper layer of the wastewater, which cannot well separate the wastewater and the impurities mixed therein, affecting the filtration effect of the wastewater, and the filtration efficiency is not good enough.

[0006] Therefore, a desulfurization wastewater zero-discharge filtration device is proposed to solve the above problems. Utility Model Content
