The invention discloses an environment-friendly exhaust gas purification device. The device comprises a gas inlet, a gas outlet, a first adsorption mechanism, a second adsorption mechanism, a gas transmission channel, a blast fan and a jet fan, wherein the gas inlet is formed in the lower end side surface of the first adsorption mechanism, the gas outlet is formed in the tail portion of the secondadsorption mechanism, the first adsorption mechanism and the second adsorption mechanism are communicated through the gas transmission channel, the blast fan is arranged at the front end of the gas outlet, and the jet fan is arranged in the gas transmission channel. Through the mode, by means of the environment-friendly exhaust gas purification device, through filtering of the double exhaust gasrecovery mechanisms, it is guaranteed that the adsorption effect of the whole adsorption step is up to 90% or above, and purified gas can be directly exhausted to the atmosphere.
