Embodiment Construction

[0024] As shown in the attached picture. For a metal smelting exhaust chimney with a diameter of about 1.5 meters and a height of 20 meters, 10 corresponding condensation rings 2 are designed, the diameter of the condensation ring 2 is 1.8 meters, the diameter of the ring pipe is 25 cm, the width of the central liquid flow tank 6 is 6 cm, and the depth is 6 cm. 4cm. The part of the ring positioned in the chimney adopts ceramic material, and the diameter of the air inlet hole 3 on the lower side of the middle part is 10cm. The part outside the chimney is made of stainless steel, and the diameter of the liquid flow hole 4 on the lower side of the middle part is 8cm, and there are 4 exhaust holes on the upper side, and the diameter is 6cm. These condensing rings are evenly installed on the chimney, about 1 / 3 part is located in the chimney, and the side slope angle between the ring and the horizontal plane is 15-20°C. In addition, fins are designed on the outer surface of the st...

Abstract

A condensing-type process and apparatus for desulfurizing fume features that a number of condensing rings inclined horizontally are arranged on the chimney. Said condensing ring is composed of the part inside the chimney, which has fume inlet holes, and another part outside the chimney, which has the condensed water outlet and exhaust holes, and has a central flow channel. The SO2 in fume is easily dissolved in said condensed water and discharged with the condensed water.

Description

technical field [0001] The invention belongs to the technical fields of chemical industry, energy and environmental protection, and in particular relates to a condensation type flue gas desulfurization method and a device thereof. Background technique [0002] Combustion of fossil fuels such as coal and petroleum, metal smelting, chemical production, etc., will produce sulfur dioxide (SO 2 ) of smoke. Sulfur dioxide discharged into the atmosphere along with flue gas will form acid rain, causing environmental pollution, destroying ecosystems such as agriculture, forestry and aquatic organisms, and endangering human health and buildings. In recent years, although various countries have adopted various measures to reduce sulfur dioxide emissions, the sulfur dioxide contained in the combustion unit mass of fossil fuels has been reduced. However, with the development of industry and population growth, the consumption of fossil fuels continued to increase, and the annual average...
