TECHNICAL FIELD
[0001] The utility model relates to dry filter technology field, concretely is a dry filter convenient for replacing filter material. BACKGROUND
[0002] As a common filter equipment, dry filter is widely used in various industries, such as chemical plant, steel plant, pharmaceutical factory, coking plant, oil refinery, etc. Waste gas generated in the production process can seriously pollute the environment and affect human health. Dry filtration can intercept many harmful substances in waste gas to meet emission standards. For example, sulfur dioxide, hydrogen sulfide, nitrogen oxides, hydrocarbons and dust particles. The filter core of the dry filter is divided into several types, among which the activated carbon filter core is the most common, with low cost and good effect. However, the activated carbon filter core also has some disadvantages: dust and other sticky substances in waste gas can easily block the voids of activated carbon, reducing adsorption efficiency. If not replaced for a long time, the filter will fail. In addition, depending on different use scenarios, the filter level is different, and the filter material used for filtering also needs to be replaced.
[0003] The combination type dry filter disclosed in the patent No. CN216630275U includes a shell device; a fine metal mesh is installed inside the shell device, and the fine metal mesh has a hollow double-layer structure; an acceleration cleaning part is fixedly connected inside the shell device; a turbulence device is installed inside the shell device; an installation part is installed inside the shell device, and a drying device is slidably connected to the installation part. The shell device is provided, and the cleaning brush on the acceleration cleaning part can automatically clean the filter coarse mesh. Cleaning the dust on the filter coarse mesh helps to improve the flowability of the filter coarse mesh. At the same time, the acceleration cleaning part can accelerate internal ventilation through the fan, effectively improving the filtering effect. At the same time, the cleaning brush can be cleaned synchronously under the driving of the fan. The filter coarse mesh can effectively filter large dust particles.
