Technical Field
The utility model belongs to ventilation exhaust field relates to a segment type wind energy exhaust apparatus.
Background
Existing ventilation and exhaust devices can be divided into two main categories: the first type is that the indoor gas is exhausted out of the room through an exhaust pipeline by using an exhaust fan or a blower, and the exhaust fan or the blower is mainly used in places such as a factory building, a kitchen and the like which are easy to generate smoke, and has the defects of consuming electric energy and increasing equipment investment and maintenance cost; the second type is to utilize the transverse airflow of natural wind power, increase the speed of the gas discharged outside in the exhaust duct through some kind of device, thus improve the ventilation effect, mainly used the not heavy place of flue gas, lie in the roof top usually, its advantage is that there is no extra energy consumption, the apparatus is simple, the investment cost is few etc.. A typical wind-powered exhaust is a widely used hood. The blast cap is a ball formed by a plurality of cambered vanes with attack angles around the axis of the blast cap and is fixed at the tail end of the exhaust pipeline through a rotating shaft. When external transverse airflow passes through, wind energy is converted into kinetic energy of the rotation of the hood, and meanwhile, the cambered surface blades with attack angles form a negative pressure area in the hood, so that gas in the exhaust pipeline is gradually sucked out. Chinese patent CN203836995U provides a wind power smoke exhaust device, which comprises a bell mouth shaped wind collecting hopper, a cylindrical wind exhaust pressure reduction cover, a wind vane, a vertical shaft bracket and a mounting base, when the airflow enters the wind collecting hopper head on, the airflow at the tail end of the wind collecting hopper is accelerated and forms a negative pressure area, thereby gradually sucking the air in the exhaust duct. Both the two technical schemes have the defects of complex structure, high manufacturing cost, easy rainwater corrosion and dust blockage of a rotating component and the like. Once the rotating member is stuck, not only the negative pressure region cannot be formed, but also the normal ventilation and exhaust of the exhaust duct is hindered. Furthermore, the malfunction of the equipment located above the roof is not easily detectable, and the maintenance work thereof is also troublesome.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a segment type wind energy exhaust apparatus can normally ventilate when the external world is calm, when the device is flowed through to the external nature transverse air current of arbitrary direction, can form the negative pressure zone at exhaust duct's end to increase the speed that interior gas of exhaust duct discharged toward the outside.
The utility model is realized in such a way that the spherical segment type wind energy exhaust device comprises an exhaust pipeline, a spherical segment body and a bracket, wherein the curved surface of the spherical segment body is over against the tail end of the exhaust pipeline; the support be the strip, the top of support is connected with the corresponding position of spherical segment curved surface one side through bolt fastener, the tail end of support is connected with exhaust duct's end through bolt fastener.
The value range of the ball radius SR of the spherical segment body is 1 ~ 2 times of the external diameter d of exhaust duct or the side length L of square pipeline, the value range of the spherical segment height H of the spherical segment body is 0.2 ~ 1.0 times of the external diameter d of exhaust duct or the long L on square pipeline side, the support length H of support, the value range of the axial distance of exhaust duct end to spherical segment curved surface is 0.1d ~ 0.5d promptly, or 0.1L ~ 0.5L.
The ball body of the utility model is a hollow shell or a solid body.
The utility model has the advantages that: when external natural airflow from any direction transversely flows through the segment body, the flow velocity of the airflow on one side of the curved surface of the segment body is greater than that of the airflow on one side of the plane of the segment body, so that a negative pressure area is formed on one side of the curved surface of the segment body, and the negative pressure area can increase the speed of the air in the exhaust pipeline to be discharged outwards. Compared with the prior art, the utility model discloses no rotating member has characteristics such as simple structure, dependable performance, with low costs, non-maintaining, practicality are strong.
