The invention provides a spraying type dust removing device for producing chemical fertilizer. The spraying type dust removing device comprises a dust removing box, an induced draft fan, a water screen, an adsorption net, a water outlet pipeline, a water inlet pipeline, a water replenishing pipe and a variable-frequency controller, wherein the bottom of the dust removing box is the detachable adsorption net; baffle plates are also arranged at two ends of the bottom of the dust removing box; the detachable adsorption net is positioned above the baffle plates; an air outlet duct is arranged at the top of the dust removing box; the air outlet duct is connected with the induced draft fan through an air outlet pipeline; the variable-frequency controller is arranged on the air outlet pipeline. According to the spraying type dust removing device for producing the chemical fertilizer, provided by the invention, spraying pipes are longitudinally arranged at intervals and the water screen is arranged above spraying mouths, so that the sprayed water makes sufficient contact with waste gas entering from an air inlet, least water resources can be utilized, and a best dust removing effect is realized; in addition, by adding the variable-frequency controller, the wind force of the induced draft fan can be adjusted according to the requirements, and further energy is saved.

Spraying type dust removing device for producing chemical fertilizer

The utility model relates to an exhaust-gas-purifying-processing tower, a tower type purifier, which is designed on the basis of various spray towers and plate towers. The utility model reserves the advantages of the spray tower and the plate tower, and refits a sieve plate, a weir and a downcomer plate of the plate tower, changing the plane sieve plate into a high hat sieve plate, replacing a weir and a downcomer plate inside the tower with a regulating tube and regulating screws outside the tower, and changing the fixed type to an adjustable type. The utility model is suitable for the departments such as the environmental protection, petroleum, chemical industry, metallurgy, etc., with the advantages of flexible regulation and convenient control. The act of the mass transfer zone (foam zone) can be fully exerted, and the total plate efficiency and the treatment efficiency are enhanced.
