[0062] like Figure 8 As shown, the sacrificial anode 200 is provided with a mounting rod 200 - 1 .

[0063] As shown in the figure, the filter baffle 105 is welded to the filter housing 100 on all sides to prevent leakage, and the filter housing 100 is divided into two parts. An anti-corrosion mechanism mounting seat 210 is provided on the filter baffle 105 to mount the filter anti-corrosion mechanism (sacrificial anode 200, anode fixing nut 230), which is fixed to the positioning step 210-3 of the anti-corrosion mechanism mounting seat 210, the filter element positioning step 103-4 of the filter element mounting seat 103.1 and the filter element mounting seat 2 through 105-3-1-anti-corrosion mechanism mounting seat hole, 105-3-2.1-filter element mounting seat hole 1, and 105-3-2.2-filter element mounting seat hole 2, respectively. At the same time, the boss mounting seat 210-2 of the anti-corrosion mechanism mounting seat 210 and the filter element boss mounting seat 103-3 of the filter element mounting seat 103 are welded to the filter element fixing plate 105-3 of the filter baffle 105 on all sides.

[0066] In summary, the connection or contact between the sacrificial anode 200 and the filter housing 100 is a metal connection, forming a galvanic cell.

[0067] The sacrificial anode 200 is a magnesium anode, a zinc anode or an aluminum anode, and has a circular, square or polygonal shape.

[0068] When using, Figure 1 As shown, unfiltered compressed air enters the filter housing 100 from the compressed air inlet flange 300, is filtered by the filter element 104, and then discharged from the compressed air outlet flange 400. The moisture and impurities filtered by the filter element 104 are collected at the bottom and discharged through the drain port 500.

[0069] In the above process, the filter housing 100 is a steel structure, and the sacrificial anode 200 is a magnesium anode, a zinc anode or an aluminum anode, which is a metal material with a relatively negative potential. When it is connected to the protected filter housing 100 and contacts with moisture in the compressed air, it preferentially dissociates itself, thereby inhibiting the corrosion of the filter housing 100. Through regular inspection and replacement, the service life of the filter can be guaranteed and the normal operation of the equipment can be guaranteed.
