Figure 1 to the drawings Figure 3 The present application will be described in detail in combination with specific embodiments.

[0023] With reference to Figures 1-3 The present application provides a kind of gas source automatic pollution discharge device of flue gas environmental protection equipment, including at least two filter assemblies 1, the top of filter assembly 1 is connected with air inlet pipe 2, air inlet pipe 2 is connected with gas source pipeline 3 away from filter assembly 1, the end of gas source pipeline 3 away from air inlet pipe 2 is connected with compressed air tank, electromagnetic valve 4 is installed on air inlet pipe 2, the bottom of filter assembly 1 is connected with air outlet pipe 5, air outlet pipe 5 is connected with gas supply pipeline 6 away from filter assembly 1, the end of gas supply pipeline 6 away from air outlet pipe 5 is connected with environmental protection monitoring equipment.

[0024] The gas in the compressed air tank enters the air inlet pipe 2 through the gas source pipe 3, and the electromagnetic valve 4 is used to control the opening and closing of the air inlet pipe 2. The gas enters the filter assembly 1 through the air inlet pipe 2, and the filter assembly 1 filters the impurities in the gas. The filtered gas enters the air outlet pipe 5 and then enters the environmental protection monitoring equipment through the gas supply pipe 6, thereby ensuring the normal operation of the environmental protection monitoring equipment. When the gas is normally supplied, one electromagnetic valve 4 can be opened, or multiple electromagnetic valves 4 can be opened. When one of the filter assemblies 1 needs to be cleaned, the electromagnetic valve 4 of the filter assembly 1 is closed, and the electromagnetic valves 4 of the other filter assemblies 1 are opened, so that the impurities in the filter assembly 1 can be cleaned. In this way, the impurities in the filter assembly 1 can be cleaned while ensuring the normal supply of gas to the environmental protection monitoring equipment, thereby ensuring the continuous monitoring of the environmental protection monitoring equipment.

[0025] The filter assembly 1 comprises a filter housing 10, and a filter core 11 is transversely arranged in the filter housing 10, which separates the air inlet pipe 2 from the air outlet pipe 5.
