The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-2, a hot-melt waste gas collecting and treating device comprises a gas-collecting hood 1, a gas-collecting pipeline 2, a pyrolysis tank 3 and a water washing tank 4, the gas collecting hood 1 is connected with a gas collecting pipeline 2, an axial flow fan 5 is arranged in the gas collecting pipeline 2, an electric heater 6 is arranged in a pyrolysis box 3, an air inlet 7 and an air outlet 8 are arranged on the pyrolysis box 3, the air inlet 7 is connected with the gas collecting pipeline 2, water is filled in a washing box 4, a gas distribution pipeline 9 is arranged in the washing box 4, the gas distribution pipeline 9 is connected with the air outlet 8, a plurality of gas distribution holes 10 are arranged on the gas distribution pipe 9, and the gas distribution holes 10 are positioned in the water, a screen plate 11 is fixed in the water washing tank 4, the screen plate 11 is positioned above the liquid level of water, activated carbon 12 is placed on the screen plate 11, a tank cover 13 covering the water washing tank 4 is arranged above the screen plate 11, and an exhaust pipe 14 communicated with the interior of the water washing tank 4 is arranged on the tank cover 13. Axial fan 5 makes and produces the negative pressure in the gas collecting pipeline 2, utilizes gas collecting channel 1 to collect hot melt waste gas and air gas collecting pipeline 2, forms the mist, and pyrolysis case 3 will mix the hot melt waste gas high temperature oxidation decomposition of air, then goes into washing case 4 and washes, and particulate matter and the gas that dissolves in water are held back by washing, and the residual gas is discharged from blast pipe 14 after passing through active carbon 12. Activated carbon 12 adsorbs particulates in the gas that are not retained by the water.

Further, a baffle 15 which is obliquely arranged is installed in the gas collecting pipeline 2, an opening 16 is formed in the middle of the baffle 15, the baffle 15 comprises a windward side and a leeward side, the leeward side is located obliquely above the windward side, a blocking piece 17 is installed on the leeward side, the upper end of the blocking piece 17 is hinged to the leeward side, and the blocking piece 17 blocks the opening 16. When the axial flow fan 5 is started, the leeward side of the baffle 15 has negative pressure, the pressure difference between the windward side and the leeward side enables the baffle 17 to tilt, the opening 16 is opened, and hot melt waste gas can smoothly pass through.
