Description

Technical Field

[0001] The utility model relates to an improved invention of a catalyst filter, in particular to an improved invention of a high-precision catalyst filter. Background Art

[0002] Most of the existing catalyst filters adopt bag filters, which cannot fully meet the requirements of fine filtration. At the same time, the catalyst is sensitive to temperature. Too low temperature will cause the viscosity of the catalyst to decrease, thereby affecting the flow rate and reducing the filtration efficiency; too high temperature will cause the catalyst to gasify, thereby affecting the subsequent production process. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a high-precision catalyst filter.

[0004] To solve the above technical problem, the utility model is implemented by adopting the following technical scheme: The high-precision catalyst filter includes a filter barrel and a filter core. A partition plate is arranged in the filter barrel. The area below the partition plate is the pre-filter area, and the area above the partition plate is the post-filter area. The corresponding filter core is arranged in the pre-filter area, and a medium inlet is arranged in the pre-filter area, and a medium outlet is arranged in the post-filter area. Its characteristics are: The filter barrel is not provided with a jacket, and a heating coil is wound around the outside of the filter barrel and wrapped with heat-insulating cotton; The filter core adopts a powder sintered filter core, and the filter cores are arranged in an array on the partition plate in the filter barrel.

[0005] There are two filter barrels on the left and right. A three-way A ball valve is connected between the medium inlets of the two filter barrels, and a three-way B ball valve is connected between the medium outlets of the two filter barrels.

[0006] A flushing port is arranged at the top of the filter barrel, and the flushing port is located in the post-filter area.

[0007] The beneficial effect of the utility model is that for the improved high-precision catalyst filter, the jacket design of the filter barrel is removed, and the external heating coil design is adopted to ensure uniform temperature, and the outside is wrapped with heat-insulating cotton to ensure that the temperature is kept constant within a certain range; The filter core adopts a powder sintered filter core, which has high filtration accuracy, good permeability and strong corrosion resistance; The top of the filter is equipped with a flushing port, and the inside of the filter can be cleaned after replacing the filter element to prepare for the replaced filter element; The overall structure adopts a double-barrel structure, and the medium inlets and the medium outlets are respectively connected by three-way ball valves, which can continuously produce without stopping the machine. Description of the Drawings
