[0048] Through the above settings, the dust cleaning efficiency can be greatly improved.

[0049] Currently, bag filters generally clean dust in the following three ways. The first is to clean the dust by mechanically vibrating the filter bags. The second is to clean the dust by the reverse suction of the fan. The third is to clean the dust by releasing compressed air or gas through nozzles. The dust cleaning effects of the first and second methods are relatively poor. Although the third method has a good dust cleaning effect, due to the large number of pulse valves and injection pipes, it has defects such as being prone to failure and easily flushing the dust to adjacent filter bags during dust cleaning. The bag filter of the present application can not only ensure an ideal dust cleaning effect but also be simple and easy to implement. Moreover, compared with the above-mentioned third dust cleaning method, the bag filter of the present application does not require compressed air, which can avoid the problem of dew condensation and hardening of the filter bags caused by using low-temperature compressed air for dust cleaning during the dust cleaning process of the bag filter for high-temperature and humid flue gas, thus affecting the service life of the bag filter.

[0050] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: When it is necessary to clean the filter bags, the driving structure drives the crank-link structure to rotate. The crank-link structure rotates and drives the connecting seat to perform a reciprocating linear motion along the first direction through the transmission rod. Since the connecting seat is connected to the filter bag hanging frame, therefore, under the cooperation of the crank-link structure and the transmission rod, the filter bag hanging frame can be driven to perform a reciprocating motion along the first direction, and further the filter bag hanging frame drives the filter bags hung on it to swing reciprocally along the first direction, so as to shake off the dust on the filter bags and achieve dust cleaning. Compared with the method of vibrating the filter bags in the prior art, the bag filter of the present application can drive the entire filter bag hanging frame to perform a reciprocating motion along the first direction, and further enable the filter bags to swing with a larger amplitude, and the dust cleaning effect is better.
