Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature resistant felt impregnated filter bags, and more specifically, it relates to a high-temperature resistant felt impregnated filter bag. Background Art

[0002] In the existing technology, the high-temperature resistant felt impregnated filter bag is a kind of filtration material widely used in high-temperature environments, which can effectively capture and filter solid particles and harmful substances in high-temperature gases. However, there are some problems in the use of this filter bag, especially in terms of fixing to the outside world. These problems are mainly manifested in the following aspects:

[0003] First of all, when the existing high-temperature resistant felt impregnated filter bags are fixed to external equipment or structures, complex fixing steps are often required. Due to the possible differences in the shape and size of the filter bags, the existing fixing methods may not be applicable to all types of filter bags. This results in that in actual operation, the staff need to spend more time and effort to ensure the firm connection between the filter bag and the external equipment. In addition, due to the cumbersome fixing process, it is easy to have misoperations, thus increasing the risk of filter bag failures.

[0004] Secondly, when the existing high-temperature resistant felt impregnated filter bags are fixed, special tools or equipment may be required. These tools or equipment may not be easy to carry or operate, further reducing the convenience of using the filter bag. In some cases, the staff may need to wait for the arrival of professional equipment to complete the fixing work of the filter bag, which undoubtedly prolongs the installation time of the filter bag and affects the operation efficiency of the entire filtration system.
