The invention discloses an environmentally friendly dust removal process for cable tunnel construction, wherein the dust extracted from the tunnel is removed by a dust removal and demisting unit and then the gas is discharged; the upper and lower ends of each third baffle plate are respectively connected to the upper inner wall and the lower inner wall of the second muffler box, and the rear end of each third baffle plate is connected to the rear end inner wall of the second muffler box; a fourth baffle plate is arranged between each two adjacent third baffle plates, and the upper and lower ends of each fourth baffle plate are respectively connected to the upper inner wall and the lower inner wall of the second muffler box, and the front end of each fourth baffle plate is connected to the front end inner wall of the second muffler box; the two ends of the dust removal and demisting box are respectively provided with an air inlet end and an air outlet end, and the liquid generated in the dust removal and demisting unit is recycled through a circulation connection unit. The invention has the advantages of improving the dust removal effect, improving the construction environment, and avoiding the situation that the dust removal effect is reduced due to blockage and the shutdown is caused to affect the construction efficiency.
