Description

Technical Field

[0001] The invention relates to the technical field of filter devices, in particular to a filter device for an exhaust pipe of a thermal power plant. Background Art

[0002] A thermal power plant refers to a factory that uses combustible materials as fuel to produce electricity. Its basic production process includes heating water to generate steam when the fuel burns. The steam drives the turbine to rotate, which in turn drives the generator to generate electricity, converting the chemical energy of the fuel into electrical energy. Thermal power plants occupy an important position in the power system. During the production process of thermal power plants, corresponding filtering devices need to be installed on the exhaust pipe to prevent waste particles in the gas from being discharged into the air.

[0003] In Chinese patent application number: CN202323667038.8, there is disclosed an installation mechanism and a filtering device for the exhaust pipe of a thermal power plant. When the exhaust pipe is inserted into the filtering assembly, the conversion assembly will be pushed to move in the functional assembly, and the translational force can be converted into a rotational force. Then, the driving assembly is driven to rotate through the transmission assembly and resist the relative movement of the clamping assembly to clamp the exhaust pipe. After the transmission assembly contacts the clamping assembly to lock the exhaust pipe, the components can be reset, thereby realizing the disassembly and assembly of the filtering assembly.

[0004] Although the above patent realizes the function of disassembling and assembling the filter assembly, the above patent has the following disadvantages when used: the above filter device lacks a cleaning mechanism for the filter screen when in use. As the use time increases, more impurities such as waste debris will adhere to the outside of the filter screen. The filter screen needs to be disassembled and cleaned, and then reinstalled after cleaning. The operation steps are relatively cumbersome, and the quality of the filtered gas cannot be detected. The function is single, which makes the device less applicable and inconvenient to use. Therefore, we propose a filter device for the exhaust pipe of a thermal power plant. Summary of the invention
