Abstract:
PURPOSE:To generate an aerosol of desired density, which makes atmospheric dust as a core and has a uniform particle diameter, without giving out a stench, by heating mixed gas of inert gas and a gasified aerosol generating liquid, and thereafter, cooling it in the air. CONSTITUTION:Gaseous CO2 A is supplied into a case 5 from a connecting port 11 having a valve 11a, from an inert gas cylinder 12. Gas A reaches a mixing nozzle 10 through a feed pipe 8, a valve 8a and a flow meter 9. On the other hand, gas A which goes into a tank 6 a dioctyl phthalate through a feed pipe 7 transfers this liquid B by pressure by a necessary quantity to the mixing nozzle 10 through a feed pipe 13, a valve 13a and a flow meter 14, and gasifies it by means of jet. In this state, the gas A and the liquid B are mixed by a necessary mixing ratio, are heated to 300 degrees or above by a heating wire 15a in a heating tube 15, and become high temperature vapor D without being oxidized. The vapor D is discharged into the air through an air port 17 from a nozzle 18, and an aerosol E is generated by a condensing operation which makes atmospheric dust as a core.

Abstract:
The invention discloses a siphon-type airbrush, comprising a front handle, a tail handle, a needle, a sprayer, a nozzle, an air inlet valve and a nozzle base. The front handle is matched and connected with the tail handle to form an airbrush body. The airbrush body is internally formed with an accommodating cavity. The accommodating cavity is internally provided with the needle. The front handle is internally provided with a siphon channel. The air inlet valve is disposed at the middle part of the airbrush body. The rear end of the nozzle base is in threaded connection with the front handle. The front end of the nozzle base is in threaded connection with the sprayer. The nozzle comprises a nozzle body; the nozzle body is pressed between the sprayer and the nozzle base; the front end of the nozzle body extends to form a nozzle tip; and an axial through-hole is disposed in the center of the nozzle base. The siphon channel communicates with the axial through-hole. The front end of the needle passes through the axial through-hole and the nozzle body and then extends into the nozzle tip. The invention has a simple and rational structure, low manufacturing cost, high stability and is conveniently processed and used.
Abstract:
The present invention discloses a method and an apparatus for mixing and atomizing a hydrocarbon stream using a diluent/dispersion stream. In one embodiment, the apparatus comprises: an inner conduit and an outer conduit concentric to each other to define an annular space, said outer conduit having an inlet for receiving the hydrocarbon stream and an outlet for dispensing a mixture comprising the hydrocarbon and the dispersion/diluent streams; a diluent/dispersion steam distributor being in connection with the inner conduit and defining a central orifice and a first set of orifices, said first set of orifices adapted to direct a first portion of the dispersion/diluent stream into the annular space and said central orifice adapted to direct a second portion of the diluent/dispersion stream into the inner conduit; atleast one contraction member and expansion member, said contraction member located downstream of the first set of orifices and said expansion member located downstream said expansion member; the inner conduit located downstream of said expansion member comprises a second set of orifices, said second set of orifices disposed on a periphery of the inner conduit and adapted to dispense a second portion of the dispersion/diluent stream into the annular space.
Abstract:
A machine (10) for environmental sanitisation comprising a system of dispensing and nebulisation (12) of a sanitising solution (SS) in an environment (AM) to be sanitised, wherein the sanitising solution, used by the sanitisation machine, is constituted specifically by an aqueous solution of hydrogen peroxide (H 2 O 2 ) and silver salts or nitrate (AgNO 3 ), and wherein the system of dispensing and nebulisation (12), included in the sanitisation machine, is configured in such a way as to dispense and nebulise the sanitising solution (SS) with a certain concentration, in the environment to be sanitised (AM), comprised between 3 ml/m 3 and 6 ml/ m 3 . Advantageously the system of dispensing and nebulisation (12) of the sanitisation machine (10) comprises a nebuliser assembly (13), of the multi-nozzle type and in particular constituted by four nebulisation nozzles (13'), apt to nebulise uniformly, at 360°, the sanitising solution (SS) in the environment (AM) to be sanitised. The sanitisation machine can operate in a totally automatic manner to perform a cycle of complete sanitisation or a cycle of preventive sanitisation, and allows all the various phases of the process of sanitisation of an environment to be programmed and kept under control, thanks to a dedicated program and a practical user interface.
