Description

Technical Field

[0001] This application relates to the field of flue gas purification technology, and in particular to flue gas purification and treatment equipment for incinerators. Background Technology

[0002] Incinerators are widely used in modern industrial production and waste disposal. However, the flue gas produced during incineration has become a major source of environmental pollution. The flue gas produced by incineration has an extremely complex composition, containing a variety of harmful substances such as acidic pollutants (e.g., hydrogen chloride (HCl), hydrogen fluoride (HF), sulfur oxides (SOx), etc.), heavy metals, organic matter, particulate matter, and nitrogen oxides.

[0003] Existing flue gas purification technologies and equipment for incinerators have many shortcomings. Some purification devices only use a single filtration method, such as simple screen filtration, which is difficult to comprehensively and efficiently purify complex flue gas components. Some traditional treatment methods have poor tolerance to high-temperature and high-pressure flue gas, which can easily lead to accelerated equipment wear and tear and a significant reduction in purification effect. In addition, some equipment cannot detect the treatment effect of flue gas in real time and accurately, making it difficult to ensure that the final emission of flue gas meets environmental protection standards.

[0004] Therefore, developing a new type of incinerator flue gas purification and treatment equipment to effectively solve the problem of harmful gas pollution in exhaust gas, improve purification efficiency and effect, and meet increasingly stringent environmental protection requirements has become an important issue that urgently needs to be addressed. Utility Model Content

A dust collection assembly is provided inside the dust collection chamber. An exhaust pipe is installed on the dust collection chamber, and an exhaust fan is installed on the exhaust pipe.

[0008] By adopting the above technical solution, the flow of flue gas can be accelerated by starting the exhaust fan. At the same time, after the flue gas is discharged through the exhaust port, alkaline liquid can be sprayed onto the flue gas under the spray of the spray assembly to remove acidic gases in the flue gas. Then the gas can enter the connecting pipe and be adsorbed by the adsorption assembly in the connecting pipe to remove heavy metals (such as Hg, Pb, Cd) and dioxins in the gas. Subsequently, the gas can be filtered by the dust removal effect of the bag filter to trap particulate matter, thereby completing the treatment and purification of the exhaust gas.

[0009] Optionally, the spray assembly includes a spray pipe installed inside the spray chamber, and a plurality of atomizing nozzles are installed on the side of the spray pipe facing the bottom of the dust collection chamber.

[0012] By adopting the above technical solution, alkaline solutions can be recovered and reused through delivery pipes and recovery tanks.

[0013] Optionally, the connecting pipe is configured as a disc shape.

[0014] By adopting the above technical solution, and through the disc-shaped setting, when the flue gas turns in the disc-shaped connecting pipe, some dust can be thrown out under the action of centrifugal force.

[0015] Optionally, the bottom of the connecting pipe is provided with a ash discharge port, and an ash discharge valve is installed at the ash discharge port.

[0016] By adopting the above technical solution, some of the ash accumulated in the connecting pipe can be discharged through the ash discharge port.

[0018] By adopting the above technical solution, most dust particles can be blocked by the dust collector bag.

[0019] Optionally, the adsorption assembly includes a slide plate installed inside the connecting tube, on which activated carbon is placed. The slide plate passes through and is slidably connected inside the connecting tube. A through hole is provided on the slide plate, and a support rod is fixedly connected inside the through hole.

[0020] By adopting the above technical solution, the adsorbent material such as activated carbon on the sliding plate can be replaced by sliding the sliding plate.

[0021] Optionally, one end of the slide plate is placed outside the connecting pipe and is fixedly connected with a pull ring.

[0022] By adopting the above technical solution, the skateboard can be slid by pulling the ring.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Alkaline liquid can be sprayed onto the flue gas under the spraying of the spraying component to remove acidic gases in the flue gas. Then the gas can enter the connecting pipe and be adsorbed by the adsorption component in the connecting pipe to remove heavy metals (such as Hg, Pb, Cd) and dioxins. Subsequently, the gas can be filtered by the dust removal effect of the bag filter to trap particulate matter, thereby completing the treatment and purification of the exhaust gas.

[0025] 2. Alkaline solutions can be recovered and reused through delivery pipes and recovery tanks;

[0026] 3. The activated carbon and other adsorbent materials on the slide can be replaced by sliding the slide. Attached Figure Description
