Abstract

The invention discloses a boiler tail gas dedusting device with a vertical low-resistance cooling system. The boiler tail gas dedusting device with the vertical low-resistance cooling system comprises a boiler discharge flue, an exhaust pipe communicated with the boiler discharge flue and a chimney communicated with the exhaust pipe. The front end of the boiler discharge flue is provided with a dry deduster, and an outlet end of the boiler discharge flue is communicated with an input end of the vertical low-resistance cooling system. An output end of the vertical low-resistance cooling system is communicated with a dedusting tank. A front end and a rear end of the exhaust pipe are respectively connected to a flue gas condenser and a wet dust collector. According to the invention, waste heat of tail gas is recovered, tail gas temperature is effectively reduced, and dust and acid gas in tail gas are effectively removed. The device of the invention is beneficial to environment protection of the atmosphere and energy-saving.

Description

technical field [0001] The invention relates to the field of boiler tail gas treatment, in particular to a boiler tail gas dedusting device with a vertical low-resistance cooling system. Background technique [0002] Traditional industrial boilers use coal as fuel, but the concentration of soot or dust generated after coal combustion is relatively high, which is very polluting to the environment. As an important equipment for production enterprises, steam boilers can provide heat sources for industrial production. During the long-term operation of steam boilers, steam with certain heat energy is provided externally by burning fuel. Putting it into the atmosphere, the discharge of high-temperature flue gas not only causes a lot of waste of heat energy, but also pollutes the environment. The exhaust temperature of the current boiler exhaust dust removal device is too high, which is not conducive to the treatment of dust in the exhaust gas. A lot of dust, waste heat and acid g...
