Problems solved by technology

[0002] In engineering fields such as ventilation and dust removal, harmful gas emission, etc., suction is inseparable, that is, the use of fans to capture harmful substances first, and then centralized treatment. But so far, the problem of how to improve the suction capacity and distance of the suction port It has been bothering various production departments and relevant scientific researchers. Although various methods and measures have been adopted, the results are not obvious.
However, because the jet nozzle is in a static state, the jet rotation strength generated is weak, and the fresh air shielding ability is small. When the escape velocity of dust or the buoyancy velocity of harmful gas is high, the suction efficiency will be greatly reduced.

Embodiment Construction

[0015] figure 1 It is a schematic diagram of the principle of the method of the present invention. see figure 1 The method for improving the suction capacity and distance of the suction port in the present invention is to set a number of jet nozzles 2 around the suction port driven by the power source to rotate around the suction port and to eject jets. The axis of the jet nozzle is inclined to the axis of the suction port. Jet flow is air flow (or steam or gas-liquid mixture).

[0016] figure 2 , image 3 It is a schematic diagram of the device structure of the present invention. see Figure 2 ~ Figure 3 The device of the present invention comprises an exhaust pipe 1A, an exhaust fan 1B installed at the outlet of the exhaust pipe, which is successively installed on the outer periphery of the exhaust pipe and is installed on the exhaust pipe through an outsourced rotary bearing 9, a gear reduction transmission mechanism 12 and a worm gear reducer 11. The rotating bellow...

Abstract

The invention discloses a method for increasing the sucking capability and distance of a suction opening. The periphery of the suction opening is provided with a plurality of efflux nozzles which are driven to rotate around the suction opening by a power source and can spray efflux. By adopting the method, the sucking capability and distance of the suction opening can be greatly increased. The method can be widely applied to the engineering fields of ventilation, dust removal and emission of harmful gas. The invention also provides a device for increasing the sucking capability and distance of the suction opening.

Description

Technical field: [0001] The invention relates to a method and device for improving the suction capacity and distance of a suction port in the fields of ventilation, dust removal and harmful gas discharge engineering. The suction capacity and distance of the suction port are improved by forming an annular jet barrier around the suction port. technical background: [0002] In engineering fields such as ventilation and dust removal, harmful gas emission, etc., suction is inseparable, that is, the use of fans to capture harmful substances first, and then centralized treatment. But so far, the problem of how to improve the suction capacity and distance of the suction port It has been perplexing various production departments and relevant scientific research personnel. Although various methods and measures have been adopted, the results are not obvious. Ordinary suction ports (even those equipped with suction hoods) have weak suction and capture capabilities for harmful substances...
