Description

Technical Field

[0001] The utility model mainly relates to the technical field of flue gas treatment, in particular to a combined spraying system. Background Art

[0002] The flue gas from the desulfurization tower contained a large amount of gypsum particles, which deposited in the flue and downstream water scrubber, causing material accumulation in the flue and scrubber, impacting system operation. Under normal circumstances, within a week of operating a melting furnace, approximately one-third of the flue flow area would be blocked by gypsum. The depth of the accumulated material in the scrubber exceeded one meter, requiring significant labor and time to clean.

[0003] By adding combined spraying, gypsum can be prevented from depositing in the flue and from being carried into downstream equipment in the water washing tower. However, the water sprayed by existing spraying equipment usually flows out of the tower along with the gypsum particles, resulting in a large amount of water waste when cleaning the gypsum particles.

At the same time, the aeration component aerates the gypsum particles inside the water source to the water surface at the high point of the water source, and then discharges the gypsum shell at the water surface into the water washing tower 2 through the sewage discharge component. The aeration component can keep the water source below the water source inside the water washing tower 2 in a relatively clean state, and the water source at the bottom of the water washing tower 2 is extracted and transported to the high point inside the water washing tower 2 through the circulation component for spraying to clean the gypsum particles, thereby realizing the recycling of the water source inside the water washing tower 2.

[0026] Please refer to Figure 1 and Figure 2 An exhaust port 3 is provided above the water washing tower 2, and the exhaust port 3 is used to discharge the gas inside the water washing tower 2.

When the aeration component aerates the water source inside the water washing tower 2, the gypsum particles in the water source will also be aerated to the water surface at the top of the water source. At this time, the water source at the bottom is relatively clean. The circulating pump 4 extracts the bottom water source through the circulating water inlet pipe 5, and then transports it to the circulating water outlet pipe 6. The circulating water outlet pipe 6 is plugged into the circulating spray head 7 set in the water washing tower 2 to spray it out, so as to clean the gypsum particles in the flue gas and realize the recycling of the water source inside the water washing tower 2.
