Boiler waste gas utilization device

Abstract

A boiler waste gas utilization device comprises a cyclone dust collector, a heat exchange water tank, a heat exchange tube, a filtering chamber and a desulfurization chamber; the lower left end of the cyclone dust collector is connected with a boiler air outlet through a connecting pipe, and the upper right end of the cyclone dust collector is connected with a first induced draft fan through an air guide pipe; the other end of the first induced draft fan is inserted from the top end of the heat exchange water tank through an air guide pipe to be connected with a heat exchange tube inside the heat exchange water tank; the lower left end of the heat exchange water tank is connected with a boiler water inlet through a water draining pipe, and the heat exchange pipe penetrates the lower right end of the heat exchange water tank to be connected with the lower left end of the filtering chamber; the right side of the upper end of the filtering chamber is connected with a second induced draft fan through an air guide pipe, the other end of the second induced draft fan is connected with a denitration chamber through an air guide pipe, and the air guide pipe is inserted into the bottom end inside the desulfurization chamber; and an exhausting pipe is arranged at the upper end of the desulfurization chamber. Energy in waste gas of a boiler can be recycled, the energy utilization rate is improved, and expenses are saved.

Description

technical field [0001] The invention relates to the field of boiler waste gas treatment, in particular to a boiler waste gas utilization device. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially in chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted has a strong smell, which seriously pollutes the environment and affects human health. [0003] Industrial waste gas emitted by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without treatment and reaches the standard, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. Toxic and harmful substances in industrial waste gas can enter the human body through the r...

Problems solved by technology

[0005]At present, most of the exhaust gas produced by domestic boilers is directly discharged into the atmosphere without treatment, which does not meet the national boiler exhaust emission standards and seriously pollutes the atmospheric environment , which not only makes the air polluted, but also makes the energy contained in the exhaust gas emitted by the boiler combustion not fully utilized. If the exhaust gas of the boiler can be recovered and generated energy, the energy utilization rate will be improved and the cost will be saved.
