Technical Field

[0001] This utility model relates to the field of pyrolysis furnace technology, specifically to a pyrolysis furnace pressure control device. Background Technology

[0002] Incineration is a major method of waste disposal. Typically, a suitable pyrolysis furnace is chosen for incineration. A pyrolysis furnace is a device that uses high temperatures to decompose waste, primarily used for waste treatment and energy recovery. Its working principle involves decomposing organic matter and other compounds in waste into gaseous, liquid, and solid products through high temperatures, thereby achieving energy recovery and waste treatment.

[0003] During operation, the internal pressure of existing pyrolysis furnaces varies with the internal oxygen content. However, existing pyrolysis furnaces typically only have one air inlet on the side. When there are many pyrolysis materials inside the furnace, the burner may not supply enough gas, resulting in incomplete combustion of the pyrolysis materials and the generation of a large amount of flue gas. This leads to an increase in gas concentration and pressure inside the furnace, increasing the danger of the pyrolysis furnace and reducing the efficiency of pyrolysis. Utility Model Content

[0018] Preferably, the crushing section further includes a gear disposed at one end of the crushing roller, and the two gears are meshed together.
