Staged pollution treatment device for thermal power plant

Abstract

The invention discloses a staged pollution treatment device for a thermal power plant. The staged pollution treatment device comprises a waste gas pipeline and is characterized in that an identification assembly is arranged inside the waste gas pipeline, a treatment assembly is arranged on the upper side of the waste gas pipeline, the identification assembly comprises an identification shaft, the identification shaft is in bearing connection with the interior of the identification assembly, cyclone fans are uniformly arranged on the outer side of the identification shaft, resistance plates are arranged on the upper sides of the cyclone fans, the resistance plates are uniformly and fixedly connected to the identification shaft, the treatment assembly comprises a rotating wheel, the rotating wheel is fixedly connected to the interior of the identification shaft, sliding blocks are slidably connected to the upper side and the lower side of the rotating wheel, the friction factor between the sliding block on the upper side and the rotating wheel is larger than that between the sliding block on the lower side and the rotating wheel, a sliding film is arranged on the outer side of the sliding block, and a fixing shell is arranged on the outer side of the sliding film. The staged pollution treatment device is characterized in that dust grains, ash and exhaust gas can be removed efficiently and energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of pollution treatment, in particular to a graded pollution treatment device for thermal power plants. Background technique [0002] During the whole process of producing electric energy in thermal power plants, the impact of various emissions on the environment exceeds a certain limit and causes the deterioration of environmental quality. These emissions include dust particles, ash, and smoke emitted from the fuel combustion process. [0003] In the process of processing dust particles, ash, and flue gas, the content of dust particles, ash, and flue gas in the flue gas is called the ash content rate. If the ash content rate is too large, the filter device may be blocked. After the filter device is blocked, it will cause excessive dust particles, ash, and flue gas inside the stove, which will affect the oxygen content, and then affect the combustion efficiency of the remaining coal. When the ash content is l...

Problems solved by technology

[0003] In the process of processing dust particles, ash, and flue gas, the content of dust particles, ash, and flue gas in the flue gas is called the ash content rate. If the ash content rate is too large, the filter device may be blocked. After the filter device is blocked, it will cause excessive dust particles, ash, and flue gas inside the stove, which will affect the oxygen content, and then affect the combustion efficiency of the remaining coal. When the ash content is low, using a high-power filter device will cause lead to waste of energy

[0004] In the prior art, dust particles, ash, and flue gas are mostly removed by filters or by high-power electric dust collectors, which will affect the combustion efficiency of the boiler in special cases
