Coke oven crude gas tedge vaporization cooling device, including water inlet, inner tube, urceolus, steam outlet, the formation heat trades the space between inner tube and the urceolus, inner tube and urceolus adoption arc transitional coupling, the inner tube both ends of tedge root are provided with refractory material, are provided with the coating in the middle of the inner tube of tedge root on the inner wall. The utility model discloses effectively avoided because revealing of arousing of the inefficacy of welding seam causes the coke oven to damage, and inner tube coating surface is smooth and tension is little, tar is difficult the bonding and the gathering in the coating, has effectively solved the problem that the coking of traditional coke oven crude gas tedge inner wall influences heat exchange efficiency.
