Desulfurization device special for oil burning boiler

Abstract

The invention discloses a desulfurization device special for an oil burning boiler. The desulfurization device is characterized by comprising a desulfurization tower body (1), wherein the bottom of the desulfurization tower body (1) is provided with a flue gas inlet (2); the middle of the desulfurization tower body (1) is provided with a spraying pipe (3); a filter material layer (4) is arranged above the spraying pipe (3); and a water distributor (5) is arranged above the filter material layer (4). The desulfurization device has a simple structure and is convenient to use, the desulfurization efficiency is over 98 percent, and emission of tail gas of the oil burning boiler can reach the standard.

Description

technical field [0001] The invention relates to flue gas treatment equipment, in particular to a desulfurization device for an oil-fired boiler. Background technique [0002] The characteristics of the exhaust gas of oil-fired boilers are that the dust content in the flue gas is very low, which is not easy to cause scaling in the system, and the concentration of sulfur dioxide is very high, which can be as high as 7000 mg / m3. The existing desulfurization system is generally a single tower type, and the flue gas is at the bottom of the equipment After entering, it is sprayed with lye during the ascent process, and then discharged after being dehydrated. The desulfurization efficiency generally does not exceed 90%, and the qualified discharge of the exhaust gas of the oil-fired boiler cannot be guaranteed after treatment. Contents of the invention [0003] The purpose of the present invention is to provide a special desulfurization device for oil-fired boilers with a desulfu...
