The application provides a kiln ventilation regulation device, comprising: a ventilation pipe; a protection shell is fixedly installed on the surface of the ventilation pipe, a connecting shell is fixedly installed on one side of the protection shell, a supporting plate is fixedly installed in the inner cavity of the ventilation pipe, a supporting rod is fixedly installed on the top of the supporting plate, and a supporting disc is fixedly installed on the top of the supporting rod. Through the design of the regulation assembly, the regulation assembly adopts a worm, a worm wheel, a rotating gear and an adjusting disc transmission structure, worm and worm wheel transmission improves stability, the rotating gear and the teeth can realize precise adjustment of the angle of the adjusting fan blade, the ventilation volume control error is reduced, the precision is improved compared with traditional manual adjustment, multiple adjusting fan blades are linked through adjusting rods and adjusting discs, the ventilation pipe inner cavity ventilation cross-sectional area can be changed synchronously, the airflow deflection problem of traditional single baffle adjustment is avoided, the kiln working condition rapid change demand is adapted, a sealing strip is arranged on the top of the adjusting fan blade, and heat loss caused by traditional baffle gap air leakage is avoided.

The application discloses a design method of a cooling tower air separation device, the cooling tower air separation device and the cooling tower, and relates to the technical field of cooling towers. The design method comprises the following steps: determining the configuration scale of a cooling tower body; determining the spacing between an air separation plate and a cooling tower shaft well, the air separation plate being arranged in an air inlet area inside the cooling tower body; determining the spacing according to the natural wind speed, the dominant wind direction and the configuration scale of the cooling tower body, and optimizing the spacing according to the packing stability under the natural wind; and determining the spacing between the air separation plates according to the wind load force distribution of the air separation plate, so as to arrange a support structure between the air separation plates, under the optimized spacing between the air separation plate and the cooling tower shaft well. The natural wind in the air inlet area is redistributed by arranging non-continuous air separation plates in the air inlet area, the air flow field state of the air inlet area is adjusted, the resistance of the natural wind passing through the air inlet area is increased, the draught is avoided, the flow field distribution of the packing area under the natural wind is more uniform, and the influence of the natural wind on the thermal performance of the cooling tower is reduced.
