Abstract
The disclosed Venturi wind barrel provides a straight section of hollow circular ring shaped tunnel body in middle part. The straight section in middle part can be in use for installing blower fan. The straight section possesses rectifying action, reduces turbulent current from occurring, and decrease kinetic energy loss of airflow. With reasonable structure, and smart design, the invention possesses high value of industry use.
Description
Technical field:
The invention belongs to the cooling device technical field, particularly relate to the manufacturing process of the device that reduces the cooling tower air velocity in the cooling tower.
Background technology:
The existing so far one-hundred-year history of cooling tower development, the wind trunk is as one of vitals of cooling tower, it act as: 1, utilize its diffusion profile, the air velocity of using cooling tower reduces, promptly reduce the dynamic pressure loss of air stream outlet, under the constant condition of power of motor, energy loss reduces, then effectively blower fan dynamic pressure and static pressure strengthen, and air quantity increases; 2, the damp-heat air that reduces or prevent to get rid of from cooling tower is back to the tower air inlet again, reenters in the tower.In traditional cooling tower, its apoplexy trunk structure generally includes two parts: 1, the converging transition of bottom; 2, the exhaust outlet straight section on top.But this kind wind trunk is unsatisfactory in design, its former because: wind trunk air outlet does not have the diffusion angle, and the air-flow of outlet can not reduce, so in fact its wind trunk has only rectified action, can only reduce the phenomenon of sinuous flow in the air-flow, and there is no actual effect for the dynamic pressure loss that reduces air stream outlet.
Summary of the invention:
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, reduce the generation of sinuous flow phenomenon, the trunk middle part that reduces the flowed energy loss is the manufacturing process of the venturi wind barrel of straight section, for achieving the above object, the technical solution adopted in the present invention is, is the manufacturing process of the venturi wind barrel of straight section in the middle part of a kind of trunk, and mainly comprise the following step: it is the trunk of the hollow circular ring shape of straight section that a middle part is provided.Owing to adopt such scheme, be not difficult to draw as drawing a conclusion, the present invention is rational in infrastructure, be skillfully constructed, the middle part straight section can be used as the blower fan construction section, and its straight section part more has rectified action, reduce the generation of sinuous flow phenomenon, reduce the flowed energy loss, have the industrial utilization of height.
Description of drawings:
Below in conjunction with drawings and Examples the present invention is described in further detail.
The structural representation of the venturi wind barrel that accompanying drawing produces for the present invention.
The specific embodiment:
A kind of trunk middle part is the manufacturing process of the venturi wind barrel of straight section, and mainly comprise the following step: it is the trunk of the hollow circular ring shape of straight section that a middle part is provided.Among the figure, this venturi wind barrel mainly is made up of the trunk 10 of a hollow circular ring shape, and the top of trunk 10 is the diffuser 11 that has cone angle, and the middle part is a straight section 12, and the bottom is a converging transition 13.When air communication was crossed the wind trunk, the converging transition of its bottom can effectively reduce airflow field flow separation phenomenon on the corner, was difficult for forming the backflow whirlpool, had reduced the flowed energy loss; The middle part straight section can be used as the blower fan construction section, and its straight section part more has rectified action, reduces the sinuous flow phenomenon and produces, and reduces the flowed energy loss; The diffuser on top increases actual air outlet area, effectively reduces its exit flow speed, and the airflow kinetic energy loss reduces, and the cone angle of its diffuser can not be excessive, otherwise easily causes the segregation phenomenon of air-flow in the corner, forms the air-flow whirlpool.
