The invention relates to a system and a method for injecting liquid odorant into a natural gas pipe, the system comprising: a tank containing the odorant in liquid form; a high-pressure pump connected to the tank; a common injection manifold fed with liquid odorant by the high-pressure pump; a plurality of odorant injectors fed with liquid odorant under pressure by the common injection manifold for the purpose of injecting the odorant into the gas pipe so as to cause it to be atomized in the gas pipe; and an electronic injection computer for controlling the injectors and the high-pressure pump.

An apparatus and a method for mixing and atomizing a hydrocarbon stream is disclosed. The apparatus comprises of an inner conduit having a first inlet for receiving the hydrocarbon stream, and a second inlet for receiving a primary dispersion stream. The inner conduit produces a primary mixture comprising the hydrocarbon stream and the primary dispersion stream. The apparatus further includes an outer conduit having a third inlet for receiving a secondary dispersion stream. Further, said inner and outer conduits together define an annular passage. The distal end of the annular passage defines a second set of orifices for allowing the secondary dispersion stream flowing there-through to come in contact with the primary mixture and thereby dispensing the secondary mixture so obtained through an outlet.

An atomizing system is provided to connect a liquid supply zone and a gas supply zone. In the atomizing system, a first pipeline is connected between the liquid supply zone and a first treatment tank, a second pipeline is connected between the first treatment tank and a second treatment tank, a third pipeline is connected between the gas supply zone and the second treatment tank. The end of each of the nozzles is connected to the other end of the third pipeline. The liquid supplied from the liquid supply zone is flowed into the second treatment tank through the second pipeline, the gas supplied from the gas supply zone is flowed into the second treatment tank through the nozzles, so that the liquid contacts the gas in the second treatment tank to produce the atomized liquid.

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.

A device for dispersing foul gaseous effluent emissions released diffusely by sources located close to the ground, in particular by wastewater treatment ponds (10, 11, 12), includes: at least two auxiliary air or gas injectors (5a1, 5b1; 5a2, 5b2; 5a3, 5b3) oriented upwards and installed in opposing zones on the periphery of each foul gaseous effluent source, such as to disperse the gaseous effluents; separate supply elements (8.1, 13a1, 13b1; 8.2, 13a2, 13b2; 8.3, 13a3, 13b3) for the injectors; and wind-direction-sensitive control elements for ensuring that at least the injector(s) best located to disperse and/or lift the gaseous effluent plume are supplied.

A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.

Disclosed herein is a refrigerator which includes a carbonated water production assembly, wherein the carbonated water production assembly includes a nozzle module provided such that carbon dioxide is sprayed in an inner portion of the carbonated water container to produce carbonated water in the carbonated water container. Through this, the carbonated water is easily produced, production components are simplified, and thus utilization of a space may be improved.

A nitrogen-enriched water generator includes an elongated housing defining a sealed nitrogen/oxygen chamber in which nitrogen molecules are combined with oxygen molecules to form a nitrate (NO.sub.3) or a nitrite (NO.sub.2) gas (NOx gas). The housing includes an NOx gas and water mixing tube, a plasma generator and a nitrogen-enriched water trap. A water spray nozzle sprays water into the chamber. At least one air injection port injects air into the chamber. A vacuum port removes a volume of NOx gas not absorbed by the water from the sealed nitrogen/oxygen chamber.

A multi-cone, multi-stage spray nozzle includes a nozzle body, a valve stem with a first valve head, and a second valve head attached to the first valve head. The first valve stem is biased into a closed position against a valve seat of the nozzle body by a bias device. The second valve head is continuously open. Upon the application of a first fluid pressure, which is less than a threshold fluid pressure, the bias device maintains the valve stem in the closed position while the second valve head is continuously open. And upon the application of a second fluid pressure, which is at least as great as the threshold fluid pressure, the valve stem moves to an open position while the second valve head remains continuously open.

The present invention relates to a dust suppression system for use in a container, and a misting apparatus therefor. In one form, the dust suppression system comprises at least one misting apparatus for contributing to the creation of a mist layer for preventing the escape of the dust from the container, the misting apparatus comprising a means for generating an airflow, and a means for producing a mist in the airflow so that the mist is carried by the airflow.
