Wet ammonia desulfurization and denitrification equipment for waste gas purification

Abstract

The invention relates to the technical field of flue gas purification devices, and discloses wet ammonia desulfurization and denitrification equipment for waste gas purification. The equipment comprises a reaction section, a precipitation section is fixedly mounted on the bottom surface of the reaction section, a motor is fixedly mounted on the bottom surface of the precipitation section, and the output end of the motor is fixedly connected with a threaded rod in a sleeving manner; and a fixed plate is fixedly mounted at the top of an inner cavity of the precipitation section, and a circulating groove is formed in the surface of the fixed plate. According to the waste gas purification wet ammonia desulfurization and denitrification equipment and the operation method thereof, after the top surface of a baffle is attached to the bottom surface of the fixed plate, the baffle seals the circulating groove, at the moment, a meshing ring is separated from the threads on the threaded rod, and a lifting plate continues to move upwards, so that sediments between the fixed plate and the lifting plate are extruded; and the sediment is compacted, and the moisture in the sediment is discharged upwards through the fixed plate, so that the moisture in the sediment is extruded and separated, the operation is simple, and the processing cost of the equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of flue gas purification devices, in particular to waste gas purification wet ammonia desulfurization and denitrification equipment. Background technique [0002] The environment is an issue related to the sustainable development of the economy. The protection of the natural and ecological environment on which human beings depend has attracted widespread attention from all over the world. Human health, so reducing sulfur dioxide emissions is one of the primary goals of improving the environment in our country. In addition, nitrogen oxides have also become a major pollutant facing our country. Sulfur dioxide and nitrogen oxides are the main pollutants that form acid rain. One of the main causes of acid mist, nitrogen oxides and nitrogen hydrides combine to form photochemical smog, which not only damages the natural environment, but also has certain harm to human health. Therefore, in order to protect the envi...

Problems solved by technology

[0003] Most of the existing waste gas purification wet ammonia desulfurization and denitrification equipment adopts adding limestone to the flue gas to make the flue gas fully contact with the limestone, so as to desulfurize the flue gas. Calcium sulfate precipitates will be generated during the reaction process, and reducing The denitrification will produce non-toxic and non-polluting nitrogen and water for discharge. However, when the existing devices extract the sediment, most of them use propeller blades to extract the sediment. The extracted sediment contains a lot of water. It is also necessary to dehydrate the sediment, the operation is complicated, and the processing cost of the device is increased
