[0022] The inner wall of the outer shell 1 is fixedly connected to both ends of the inner sintered filter element 2. The inner wall of the inner sintered filter element 2 corresponds to the outer surface of the middle tube 3. The middle tube 3 is used to connect the inner sintered filter element 2. The two ends of the outer sintered filter element 4 are fixedly connected to both ends of the inner wall of the outer shell 1.

[0023] The two ends of the filter element housing 50 are fixedly connected to the two ends of the inner wall of the housing 1. There are several heat conduction rings 51, which are fixedly installed at equal intervals on the outer surface of the filter element housing 50.

Each heat conduction ring 51 has several round holes on one side to facilitate temperature conduction. One side of the inlet pipe 52 is fixedly connected to one side of the housing 1. The inner wall of the inlet pipe 52 is connected to the space between the housing 1 and the filter element housing 50.

[0024] Install the high-temperature, high-pressure corrugated sintered metal filter element into the designated position, ensuring all connections are properly sealed to prevent gas leakage. Connect the temperature regulating medium, such as a heating liquid or gas, through the inlet pipe 52 to prepare for temperature regulation of the filter element. Example 2

[0025] Based on the above embodiment 1, please refer to Figures 3-5 There are several collecting plates 54, and the bottom surfaces of several collecting plates 54 are fixedly connected to the bottom surface of the inner wall of the outer shell 1. The lower parts of several guide plates 53 are fixedly connected to one side of a collecting plate 54.

[0026] The collecting plate 54 is used to collect the water condensed on the guide plate 53 to the surface. The top surface of the collecting plate 54 is inclined, and the bottom surface of the collecting plate 54 is fixedly connected to the bottom surface of the outer shell 1.

[0031] Temperature regulation: Activate the temperature regulation system to introduce the heating medium into the space between the filter element housing 50 and the housing 1 through the inlet pipe 52, and to evenly conduct it to all parts of the filter element through the heat-conducting ring 51. Adjust the flow rate and temperature of the heating medium to ensure that the temperature of the filter element is consistent with or slightly higher than the temperature of the gas to be filtered, thereby preventing condensation caused by temperature difference.

[0032] Filtration Operation: After the temperature stabilizes, start the filtration system, allowing the gas to be filtered to enter the inner sintered filter element 2 through the central pipe 3, and then pass through the outer sintered filter element 4 for filtration. The filtered gas continues to flow, while impurities are captured by the filter elements.

[0033] Condensation Prevention and Drainage: Although the primary design objective is to prevent condensation through temperature regulation, components such as the baffle plate 53 and the collecting plate 54 serve as supplementary measures. If a small amount of condensate is generated due to extreme conditions or operational errors, the condensate will be guided by the baffle plate 53 to the collecting plate 54 and safely drained through the outlet pipe 55, the bend pipe 56, and the drain pipe 57.
