Abstract

The invention belongs to the technical field of flue gas waste heat recovery, and discloses a flue gas waste heat recovery system and method for air pollution control. A water tank is installed at thetop of a case body, and a pressure gauge and a temperature gauge are arranged at the two sides of the water tank respectively and used for monitoring the change conditions of the pressure and temperature in the water tank in real time; meanwhile, a water inlet valve and a water outlet valve are installed at the outer portion of the water tank, and the water inlet valve is connected with a water inlet pipe. The water inlet valve and the water outlet valve are connected with the water tank through pipeline through rings. An activated carbon filtering net layer and a drawer-type filtering surface layer are laid in a filtering device in the case body and can effectively adsorb small solid particles or sulfur dioxide and other gas in waste flue gas and improve the working efficiency. The pipeline through rings between the water inlet valve and the water outlet valve can activate water molecules, prevent the formation of scales and reduce the water corrosion to pipelines. Two symmetrical bases are installed at the bottom of the case body to achieve a symmetric effect.

Description

technical field

[0001] The invention belongs to the technical field of flue gas waste heat recovery, and in particular relates to a flue gas waste heat recovery system and method for air pollution control. Background technique

[0002] Smoke is very common in industrial production, and is often the most exhaust gas in the production of many heavy industrial machinery. Especially in some industries with high energy consumption and serious pollution. The random discharge of waste flue gas containing a large amount of heat into the air will not only cause energy loss, but also pollute the air environment to a certain extent, posing a great threat to people's health. And if this part of waste flue gas can be recovered and the heat carried by it can be converted into other energy, it will not only reduce the pollution to the environment but also improve the efficiency of energy utilization. However, at present, no matter whether it is industrial treatment or market production, ...
