The invention relates to an oil gas condensation preventing gas collecting umbrella of a charring chamber of a vertical furnace. The umbrella comprises a gas collecting umbrella which is arranged in the charring chamber of the vertical furnace; the gas collecting umbrella is composed of a coal gas eduction tube and a coal gas collecting umbrella which are connected, wherein the coal gas eduction tube is arranged in a pre-heating section and a low-temperature section of the charring chamber, and the coal gas collecting umbrella is arranged in a dry distillation section of the charring chamber; the coal gas eduction tube is composed of an inner sleeve and an outer sleeve to form a jacket structure, and a heat insulating layer is arranged in the jacket structure. Coal gas generated by in the dry distillation section of the charring chamber of the vertical furnace is collected by using the coal gas collecting umbrella, oil gas condensation is prevented by way of arranging the jacket structure of the coal gas eduction tube and the heat insulating layer to prevent the gas collecting umbrella from being blocked, so that coal gas generated in the dry distillation section in the charring chamber can be quickly and smoothly derived out, and therefore, safety and stability of production of the vertical furnace are guaranteed.
