SK285519B6 - Device for production of aerosol - Google Patents

Abstract

Device for production of aerosol is designated mainly for fire apparatus and also for atomisers in several ar-eas industry. Device consists of throttling accelerating nozzle which is produced by tapered surface of inlet gas (3), which is solid and of tapered surface of inlet liquid (4), wherein system of opening inlets of liquid (5) is situated. Tapered surface of the inlet gas (3) and tapered surface of the inlet liquid (4) are against each other axially converted.

Description

Technical field

The invention relates to a device for the production of an aerosol intended especially for fire extinguishing technology and for sprayers of various uses, for example for chemical spraying in agriculture.

BACKGROUND OF THE INVENTION

For the production of an aerosol, devices are used in which the liquid exiting the ejector located in the axis of the atomizing nozzle is sprayed, or the liquid is supplied under high pressure centrally to the atomizing nozzle associated with the ambient atmosphere. Their drawback is the need for a high-pressure liquid supply as well as spraying into a space associated with the surrounding atmosphere, with ejectors being small flow rates.

Also known are aerosol generating devices comprising an annular chamber-shaped body (SK 282655) fitted with a plurality of orifices and nozzles oriented axially and radially, enabling the production of an aerosol cyclone exiting into the environment, which need not be directly associated with the atmosphere.

Another known solution is the Fire Control Method and Device, protected by EP 0 314344, or the Snow Cannon, protected by FR 2 376384. The disadvantage of these devices is their structural complexity, high number of structural elements and thus an increased probability of operational failures.

1. The gas enters the device through the space 31, the liquid enters the space 41.

Industrial usability

The aerosol generating device of the invention can be used in various fields of technology, but especially where there is a requirement for the small size of the device, its operational reliability, and large aerosol mass volumes. The priority area of application is fire extinguishing technology for mobile and stationary equipment.

1 drawing SUMMARY OF THE INVENTION The above-mentioned disadvantages of the known solutions are eliminated by the aerosol generating device according to the invention, which consists of a throttle nozzle, characterized in that the throttle nozzle is formed by a conical gas inlet surface which is integral and a conical liquid inlet surface in which a plurality of apertures is located. liquid inlet. The conical surface of the gas inlet and the conical surface of the liquid inlet are axially adjustable relative to each other. By controlling the position of the conical surfaces, the velocity and the amount of the incoming gas are regulated. Overview of the figures in the drawing BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail with reference to the drawing of FIG. 1 shows a longitudinal section through a device according to the invention and FIG. 2 is a longitudinal section through the device structurally derived from FIG. 1 in an inverse manner. DETAILED DESCRIPTION OF THE INVENTION The device of FIG. 1 and 2 consists of a throttle nozzle formed by a conical surface of the gas inlet An aerosol generating device, comprising a throttle nozzle, characterized in that the throttle nozzle is formed by a conical gas inlet surface (3) which is integral and a conical surface of the liquid inlet (4) in which a plurality of inlet orifices is located liquids (5). An aerosol generating device according to claim 1, characterized in that the conical surface of the gas inlet (3) and the conical surface of the liquid inlet (4) are axially adjustable relative to one another. 3, which is an integral and conical surface of the liquid inlet 4. In the conical surface of the liquid inlet 4 there is a set of liquid inlet openings 5, the cross-section of the throttle nozzle is controllable by the axial adjustment of the conical surface of the gas inlet 3 and the conical surface of the liquid inlet 4 by means of a sliding control element 2 located in the housing of the device.
