(57) Abstract:

Usage: industrial ventilation or wind. The inventive baffle includes a vertical inlet pipe 1, the rotary cone 3 having the shape of the hull with a curvilinear generatrix on the outer surface of which is made evenly placed air intake cone-shaped trench 5, an internal cavity which communicates with the cavity of the diffuser 3. 2 Il.

The invention relates to a special technique and can be used in industrial ventilation and wind.

In industrial ventilation apply multiple devices connecting the air in an enclosed space with the external environment. The principle of operation of such devices is based on the difference between the barometric pressure inside and at the mouth of the exhaust pipe. In addition, industrial ventilation principle is used based on the different densities of hot and cold air. On the first principle at higher differences of barometric pressure floor premises are closed and the top of the pipe the air indoors will increase [1].

Apply and other devices ventilation is about (for example, on the roof of the premises). The higher the force of the wind, the higher the diffusion and injection and, consequently, higher air exchange.

This principle is widely known deflector [2], which is the closest to this invention. In its technical essence and coincidentally General technical characteristics this device is a prototype.

The disadvantage of this device is the relatively low efficiency.

To achieve higher technical result and, above all, improve efficiency, offer on the outlet baffle to mount the angular rotary cone having a cone shape with a curvilinear generatrix on the outer surface of which is made evenly placed air intake cone-shaped chute, an internal cavity which communicates with the cavity of the cone.

In Fig. 1 shows a General view of the device of Fig.2 cone-shaped chute.

The deflector includes a vertical inlet pipe 1, mounted in bearings 2, the rotary cone 3, the intake chute 4 and the vane 5.

When windy weather vane 5 determine the direction of a main who's flow is achieved due to the velocity difference of the air flow, ambient outside corner diffuser 3, and flowing out of the diffuser.

DEFLECTOR comprising a vertical inlet rotary diffuser with air intake device, characterized in that it is equipped with vanes, and the suction device is designed as a cone-shaped grooves spaced equally on the outer surface of the cone having a cone shape with a curvilinear generatrix, the internal cavity of each chute is in communication with the cavity of the cone.
