Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] The present invention is a fish scale petal type semi-straight tube coke oven riser waste heat recovery device, such as figure 1 As shown, the fish scale flap type semi-straight tube coke oven riser waste heat recovery device is composed of a cylinder body, a semi-circular casing, a scaled semi-straight tube or overlapping semi-straight tubes, an inlet pipe and an outlet pipe from the inside to the outside. The inner wall of the cylinder is coated with a high-temperature resistant coating, which can effectively alleviate the coking phenomenon during the heat exchange process of the raw gas. The lower end of the cylinder is connected with the roof of the coke oven, from which the raw coal gas enters the riser, passes through the cylinder and enters the gas collection chamber from the upper end of the cylinder. A water inlet is set at the lower end of the semi-an...
