The present invention concerns a method and a device for feeding at least one chemical substance into a main process stream. The method of the invention comprises the steps of providing a concentrated stream of said chemical substance, mixing said concentrated stream with a diluent stream to provided a diluted stream of said chemical substance, injecting said diluted stream of said chemical substance into said main process stream, wherein said mixing of said concentrated stream with said diluent stream is effected by injecting a jet of either one of said concentrated stream or said diluent stream into the respective other stream. The device of the invention comprises a first pipe segment (21) having a first inlet (22) for a first fluid and a first outlet (23) for a mixed fluid, a second pipe segment (24) having a second inlet (25) for a second fluid and a second outlet (26) connected to and leading into said first pipe segment (21) between said first inlet (23) and said first outlet (24), and first connection means (27) for connecting said first outlet (23) of said first pipe section (21) to a main pipe (14) of said main process stream, wherein said second pipe segment (24) comprises at least one nozzle (28) for generating a jet (29) of said second fluid arranged upstream of said second outlet (26).

A truck for loading emulsion explosive in field with intrinsic safety, with its key improvement being a static emulsification device and a static sensitizing device to perform emulsification and sensitization, wherein, an outlet of the static emulsification device is connected with a transporting hose, a terminal end of a sensitizer storage transporting system is connected to a starting end of the transporting hose, and the static sensitizing device is arranged at a terminal end of the transporting hose. Its advantages include the transporting of emulsion explosive product is avoided, thereby reducing safety risk; on the other hand, the emulsification device and sensitizing device utilized by this truck both have static structure, so that there exists no shear or mechanical friction during the emulsification and sensitizing process, thereby reducing sensitivity, preventing explosion form happening in the production process, and ensuring production safety.

The present application is directed towards systems for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.

The present invention relates to a process for the insertion and conveying of a labile additive, or a mixture thereof, in a transporting pipe, in which a main stream of molten material flows, said process characterized in that it incorporates said additive, or said mixture, in a portion of the pipe delimited by the main stream, according to one of the following alternative modes: a) in a longitudinal direction with respect to the flow direction of the main stream of molten material, or b) in a transversal direction with respect to the flow direction of the main stream of. molten material, or c) according to a composition of the longitudinal (a) and transversal (b) mode, thus forming a resulting stream which keeps the labile additives segregated from the main stream of molten material.

Methods, processes, and apparatuses for preparing and transporting bitumen. Bitumen may be prilled such that a bitumen product comprising a prill core and a non-stick coating is produced. The non-stick coating may comprise asphaltenes and the prill core may comprise bitumen, deasphalted oil, or both bitumen and deasphalted oil. The resultant non-stick coated prills have reduced adhesion to transportation vessels and other non-stick coated prills at a temperature below an adhesion temperature, facilitating transport.

A fogger apparatus and related methods are disclosed. The fogger apparatus includes a portable fogger body. A DC blower motor is positioned on the portable fogger body and is powered with a battery, wherein the DC blower motor produces air flow through at least one passageway within the portable fogger body. A quantity of fogging liquid is housed within a container positioned on the portable fogger body, wherein at least a portion of the quantity of fogging liquid is dispensable from the container. An activation switch controls at least one of activation of the DC blower motor and dispensing of the portion of the quantity of fogging liquid. A mixing chamber receives the air flow and the dispensed portion of the quantity of fogging liquid. The dispensed portion of the quantity of fogging liquid is expelled through a nozzle as a particulate having adjustable droplets sizes.

The present disclosure provides a microbubble generation container and a water discharging device. The container includes a barrel main body, an excitation member and an elastic member. The barrel main body is provided with a water inlet, a water outlet and a connecting port. The excitation member is movably arranged in the barrel main body, and includes a partition plate and a sealing portion. The partition plate divides an inner space of the barrel main body into a first chamber and a second chamber, and a water passage for communicating the first chamber with the second chamber is arranged on the partition plate. The water passage enables water flowing by to form water droplets and be ejected. The sealing portion opens and closes the connecting port with a motion of the excitation member.

A cavitation plate and system comprises a plurality of flow elements through the thickness of the cavitation plate. Each of the plurality of flow elements comprises an inlet channel a converging nozzle coupled to the inlet channel, a throat in fluid communicating with the converging nozzle, a diverging diffuser in fluid communication with the throat and an outlet channel in fluid communication with the diverging diffuser.

A method and high-pressure mixing device for co-injection of polymeric reactive components, in particular for polyurethane and epoxy mixtures. The polymeric components are supplied in a common pressure chamber where they flow at a same pressure and in an unmixed state into a forwardly converging fore portion of the pressure chamber, and through a settable co-injection orifice to be co-injected, in the unmixed state, into a mixing chamber transversely oriented to the pressure chamber. The settable co-injection orifice consists in an elongated restriction that longitudinally extends on a side wall of the mixing chamber orthogonally oriented to an intersecting the forwardly converging fore portion of the pressure chamber; a first cleaning member and a second cleaning member are sequentially reciprocable in the pressure chamber to eject the remaining unmixed polymeric components, respectively in the mixing chamber to eject the remaining mixture, and stop elements are provided to set an open section of the elongated restriction, by adjustably stopping the fore end of the cleaning member for the mixing chamber, in respect to the same elongated restriction of the co-injection orifice.
