Rotary spraying device for desulfurization process of desulfurization tower

Abstract

The invention provides a rotary spraying device for the desulfurization process of a desulfurization tower, and relates to the technical field of desulfurization towers. The rotary spraying device forthe desulfurization process of the desulfurization tower comprises a tower body, the inside of the tower body is fixedly connected with a rotating device by a support rod, the inner bottom end of thetower body is provided with a water trough, the bottom of the water trough is fixedly connected with a water pump, a circulating water tube is fixedly connected to the periphery of the water pump, and the circulating water tube is connected with a water spray tube to make the water pump extract a dust remover into the water spray tube. The rotary spraying device for the desulfurization process ofthe desulfurization tower realizes the automatic rotation of the water spray tube, enlarges the spray range of the water spray tube, avoids power components from being used in order to save energy, and can enlarge the water outlet area of water outlets interstitially in the spray process to make remaining dusts flow out from the water outlets and avoid the dusts from clogging nozzles.

Description

Technical field [0001] The invention relates to the technical field of desulfurization towers, in particular to a rotary type desulfurization tower spray device for the desulfurization process. Background technique [0002] Desulfurization tower is a kind of tower equipment for desulfurization treatment of industrial waste gas. It is widely used in the flue gas treatment of coal-fired industrial boilers and kilns because of its easy maintenance and the advantages of achieving both dust removal and desulfurization effects. The principle of its use is the principle of water film desulfurization and dust removal, so it is necessary to install a spray device of dust removal agent inside the desulfurization tower. [0003] In order to increase the range of spraying, the traditional sprinkler device will open more spray holes around the sprinkler pipe. However, a larger water pressure is needed to achieve the spray effect, thereby increasing the power consumption. Consumption, while the...

Problems solved by technology

[0003] In order to increase the range of spraying, the traditional spraying device will set up more spraying holes on the periphery of the spraying pipe, but therefore requires a larger water pressure to achieve the effect of spraying, thereby increasing the power consumption. Consumption, while the traditional rotary spraying device is driven by a motor, which also consumes electric energy. The dedusting agent sprayed in the desulfurization tower is recycled in the tower. After spraying, it falls into the bottom of the tower and is pumped to the top by the water pump Spraying, because the dedusting agent will absorb a lot of dust after spraying, and in order to increase the contact area between the dedusting agent and the flue gas, the general spray port is very narrow to produce small water droplets, so it is easy to cause the spray port to be damaged. jam
