Description
Technical field
The utility model relates to a kind of cooling tower air duct of Anti-Typhoon desertification dust storm, belongs to the used for cooling tower fiberglass ventilating duct in the industrial circulating water machine aerating and cooling tower equipment.
Background technology
At present the present situation of cooling tower is, 1, the task of cooling tower is the negative pressure of utilizing blower fan to produce, and the effect at the air atmospheric pressure enters cooling tower, carries out heat exchange, reaches the effect of coolant water temperature.Therefore, require same cooling tower, same power of motor air capacity to be the bigger the better.2, under the condition of given tower, blower fan, power of motor, the air quantity of cooling tower is relevant with the shape of air duct, requires air duct center of curve symmetry, and the blower fan blade tip equates apart from the air duct distance.3, in western certain the coastal petroleum chemical enterprise cooling tower actual measurement process in Guangdong, find, since typhoon influence, the air duct gross distortion, and fan delivery reduces nearly (60-52)/60=13%, means that the disposal ability of cooling tower reduces 13%.4, the distortion of cooling tower air duct is because the effect of extraneous wind-force causes, and mainly is that the coastal tropical storm and the sandstorm of the Northwest cause.Therefore, in the area that the severe storm influence is arranged, the air duct of cooling tower should have the ability of wind resistance force deformation.5, the distortion because of air duct causes fan blade to damage also happening occasionally of causing the accident, and there are certain threat in safety in production and personal safety.
Summary of the invention
The purpose of this utility model is to provide a kind of cooling tower air duct of Anti-Typhoon desertification dust storm, the technical scheme that its technical problem that solves the utility model adopts is: one, establish steel design in the junction of forming between air duct fan section and the air duct wall assembly, link together with the air duct wall of fastening bolt, increase air duct and blower fan place wind resistance and become ability steel design; Two, the end face at air duct wall seam crossing is provided with belt steel plate, on the steel plate that goes in ring fabrication hole is set, and fastening bolt is installed in the hole, pastes in the process it is directly papered in the air duct pars intramuralis, strengthens the ability that air duct hoop and vertical wind resistance become; Three, in air duct wall manufacturing process, (being the aditus laryngis place) is provided with a circle V-shape annular keel bracing frame in the air duct wall at the narrowest position of air duct, support and adopt the 10mm reinforcing bar to be welded, gap in the V-shape annular keel bracing frame and the gap between V-shape annular keel bracing frame and the air duct wall are filled with the polyurethane foam layer, and the cross section of V-shape annular keel bracing frame is V-shaped; Four, also be provided with belt steel plate in air duct air outlet place flange, directly paste moulding with fiberglass, characteristics such as this strengthening process has steel part not to be exposed, corrosion-resistant combine with air duct is whole.Service life is identical with fiberglass; Five, be vertically arranged with the steel plate reinforcement in the air duct wall, by bolting, junction, steel plate reinforcement top adds the arc angle steel two is combined closely between the sheet of steel plate reinforcement and the sheet; Six, be vertically arranged with the sheet gripper shoe at the window place of air duct wall, fix by fastening bolt between two groups of sheet gripper shoes.
The beneficial effects of the utility model are, the cooling tower air duct of this Anti-Typhoon desertification dust storm is vertical and hoop is firm by air duct, strengthen the ability that the air duct wind resistance becomes, ensure the air quantity of cooling tower, ensure the disposal ability of cooling tower, reach cooling-down effect, increase the service life of cooling tower air duct, make fan operation safe and reliable, requirement guarantees safe production.
