Embodiment Construction
[0013] The device of the present invention is arranged at the end of the flue.
[0014] The flue box 2 is divided into multiple stages by the partition 4. The flue gas enters the device through the flue gas inlet pipe 1, and its flow velocity immediately drops to 0.01-1.0 m / s. Under the guidance of the partition 4, the flue gas Flowing in the flue box 2, the nozzle 3 arranged on the top of the box continuously sprays the turbid liquid mist of the water-based dust adsorbent, and the combination of the liquid mist and the dust particles grows continuously. When the screen is collected, it will drip on the screen. The dust removal effect is achieved through the above process.
[0015] While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation to cover all modifications and ...

The invention relates to a dust removal device for various dust emission pollution treatment, and belongs to the technical field of dust removal. The dust removal device comprises a flue gas inlet pipeline, a flue channel box body, a spray nozzle, a partition plate, a trapping wire net and a chimney, and further comprises a water-based dust suspension supply and atomization host system. Accordingto the invention, the flow velocity of flue gas in the device is reduced to 0.01-1.0 m / s, the flue gas is guided to flow through the partition plate, a water-based dust inhibitor suspension liquid with an atomization precision of less than 50 microns is continuously sprayed to the flue gas through the spray nozzle, liquid mist and dust particles are combined to grow up continuously, and the dust removal effect is achieved through gravity dripping and / or dripping after being attached through the trapping wire net; and the device has the characteristics that the dust removal effect can reach less than 8-10 mg / m<3>, equipment is simple and easy to implement, and the investment and operation cost is low.
Description
Technical field: [0001] The invention relates to a dust removal device used for pollution control of various dust discharges, and belongs to the technical field of dust removal. Background technique: [0002] Dust is generated in many production and living processes of human beings, and the emission of dust pollutes the atmospheric environment. In order to prevent dust emissions from polluting the atmospheric environment, various dust removal methods have been adopted. The current general dust removal methods include: wet dust removal, which generally uses water washing for dusty flue gas; gravity dust removal and centrifugal dust removal, relying on large particle size dust to free Landing or centrifugal acceleration to capture particulate matter; electrostatic dust removal, so that the dust passes through the high-voltage electric field, and the particles are charged to move, thereby capturing the dust; bag dust removal, mainly by pressurizing the dust, making it forcibly ...
