Embodiment Construction
[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0018] The present invention is described further in conjunction with accompanying drawing, as figure 1 , figure 2 As shown, the working process of a system for collecting and stabilizing the non-condensable gas of the pyrolysis furnace is as follows: first, the non-condensable gas is washed with alkali to remove acid, and the non-condensable gas generated by the pyrolysis process enters the alkali-wash tower, and is sprayed by alkali-wash The pump circulates and sprays the lye to remove the acid gas in the non-condensable gas. During the cyclic spraying process, an online pH meter is used to detect the concentration of the lye. When the pH value of the lye is 12, close the waste liquid valve, ...
