[0003] In the prior art, the authorized patent with publication number CN221015169U discloses a flue gas spray purification device, including a spray purification box and a purified water tank. A water pipe is fixedly connected to the upper part of the spray purification box, and several spray heads are fixedly connected to the bottom end of the water pipe. A flue gas spray chamber is opened inside the spray purification box, and a sedimentation tank is provided at the bottom end of the flue gas spray chamber. A baffle is fixedly connected to the upper side of one side of the sedimentation tank, and a return pipe is provided above the baffle. A purified water tank is provided on one side of the spray purification box, and a filter sand box is inserted into the upper side of the inner side of the purified water tank. This utility model, with its spray chamber, purified water tank, spray heads, and sedimentation tank, allows water to flow into the flue gas spray chamber. Simultaneously, a water pump draws spray water from the purified water tank and flows it through the water pipe to the spray heads, spraying it downwards to dislodge dust and mixed impurities in the flue gas. The wastewater and impurities after spraying flow into the sedimentation tank.

Multiple evenly distributed second spray heads 18 are fixedly installed on the bottom wall of the second liquid distribution chamber 17. The third liquid guide pipe 16 can introduce spray liquid from the corresponding first liquid guide pipe 6 into the second liquid distribution chamber 17. After being sprayed by multiple second spray heads 18, the flue gas passing through the pretreatment box 8 is pre-treated.

[0024] A connecting pipe 19 is fixedly installed on the pretreatment box 8. The connecting pipe 19 is fixedly installed on the purification box 1 and is used to introduce the spray liquid collected in the pretreatment box 8 into the purification box 1.

Three staggered air-blocking blocks 2 in the purification box 1 allow the flue gas to flow upwards through the gaps between the three blocks and be discharged through the exhaust pipe 11. The three staggered air-blocking blocks 2 extend the path of the flue gas through the purification box 1, and the flue gas is purified by spraying liquid through the first liquid distribution chamber 3 and the first spray head 4 located on the air-blocking blocks 2. Sufficient purification is achieved when passing through the gaps of the three air-blocking blocks 2, improving the flue gas purification effect. The filter screen 14 installed in the pretreatment box 8 can filter the flue gas entering the pretreatment box 8, filtering out large particulate impurities in the flue gas, thus achieving flue gas filtration. The second liquid separation chamber 17 and the second spray head 18 installed in the pretreatment box 8 can perform preliminary pretreatment on the flue gas passing through the pretreatment box 8. Combined with the secondary purification treatment in the purification box 1, the purification effect of the flue gas can be further improved, ensuring sufficient purification of the flue gas.
