The remarkable effects of the utility model are: 1. Since the utility model adopts several filter bag gas-solid separation and purification modules to be superimposed, the whole unit can be changed by simply increasing or decreasing the number of filter bag gas-solid separation and purification modules according to actual needs. The size, shape and processing capacity of the equipment are suitable for small or medium and large enterprises to choose according to their needs. The utility model can effectively purify dust-containing gas.

2. The components in the modular combination bag type gas-solid separation and purification device can be mass-produced in the factory, with simple structure and convenient assembly on the construction site. the

3. In the application of the utility model, the equipment modification is more convenient. For the existing equipment, the number of gas-solid separation and purification modules of the filter bag is increased or decreased, so that the equipment can better exert the gas-solid separation efficiency.
