Description

Technical Field

[0001] The utility model relates to the technical field of straw processing, in particular to a crop straw burning and smoke removal device. Background Art

[0002] Straw is the mature stem and leaves of a crop, mainly the remaining part after the fruits of corn, sugarcane, cotton, wheat and other coarse grains are harvested. The straw burning device can burn the straw in a relatively sealed space, and the ashes produced can be used as fertilizer. At the same time, it is also necessary to filter the inhalable particles in the flue gas. Most of the current straw burning devices use filters at the exhaust to filter the particulate matter.

[0003] For example, a smoke removal device for burning crop straw disclosed in publication number CN219815748U sprays water on the surface of the filter through a horizontal pipe and a nozzle to clean the filter and avoid clogging of the filter. The connecting column, movable plate and vertical column are driven to reciprocate up and down by a hinged rod, so that the horizontal pipe and the nozzle reciprocate up and down to spray evenly and clean more comprehensively.

[0004] However, when the cleaning structure is in use, the horizontal tube and the nozzle can reciprocate up and down to clean only one side of the filter, so that the cleaning range of the filter is not enough when cleaning, which affects the use; in view of this, we propose a crop straw burning smoke removal device.
