A fluid mixing apparatus is provided in which pressure plates and collection plates are stacked alternately, with cavities between, the pressure plates each having an annular band of fine flow holes while the collection plates each have one or a small number of comparatively large flow-holes eccentrically disposed in relation to the center of the plate. The cavities between the plates can be provided by depressions formed in both faces of each collection plate. The pressure plates can each advantageously comprise a mesh or screen structure to provide the fine flow-holes.
Homogenizing apparatus having a stack of disc valves made of stainless steel having a Brinell hardness from 40-42. A hydraulic actuator for applying a force to the stack of disc valves is spaced above the valve disc housing, the space therebetween being vented to the atmosphere to prevent hydraulic leakage into the valve housing. The disc valves are maintained in stacked relationship by stainless steel rods having their lower ends welded to a bottom plate supporting the stack of valve discs. To enhance the washing and cleaning of the apparatus radii are provided on all of the corners of the fluid contacting components which have angles less than 135.degree..
An apparatus to mix various liquids in fluid streams includes an outer casing with a plurality of fluid inlets and a fluid outlet, and a plurality of discs bearing a plurality of different holes or groove arrangements stacked one upon another between the fluid inlets and outlet to induce a rotational angular velocity to the fluid streams.
An apparatus for fluid flow communication is disclosed which comprises a substantially tubular member having first and second opposite end portions; a first end wall secured to and closing the first end portion of said substantially tubular member wherein the first end wall has at least one first aperture extending therethrough; a second end wall secured to and closing the second end portion of the substantially tubular member wherein the second end wall has at least one second aperture extending therethrough; an intermediate wall disposed within the substantially tubular member intermediate the first and second end walls and having a circumferential outer edge; and support means disposed within the substantially tubular member for fixedly securing the intermediate wall relative to the inner surface of the substantially tubular member whereby the circumferential outer edge of the intermediate wall and the inner surface of the substantially tubular member define a substantially annular passage. A process for mixing a drilling fluid comprises passing components of the drilling fluid through the apparatus.
The invention features an emulsifying module comprising a cylindrical body (1) with a direct input block (5) or mixing block (4), at one of its ends, and an adjustable output block (3) at its other end. The body (1) contains one or more hollow cylindrical cartridges (8) allowing the mixture to pass through the cartridge from one end to the other. The cartridges (8), linked with one another and with the end blocks of the tubular body (1) via resilient spring linking mechanisms (14 to 18), each contain a plurality of vibrating discs (24) slidingly mounted on a hollow central axle (25). The hollow central axle (25) has a plurality of oscillating discs which cover and uncover lateral outlets provided in the axle to facilitate mixing. This invention is useful for emulsifying numerous liquid or gas products, in particular greasy liquid products, fuels, motor fuels, oils in various applications, heating, energy, compound products, and engines.
A method of foam emulsion well cleanout for gas well. An emulsifier apparatus is provided having a compressed air inlet, a foaming solution inlet and a foam outlet. The compressed air inlet is connected to a source of compressed air capable of supplying compressed air to the emulsifier apparatus within a range of selected pressures. The foaming solution is connected to a source of foaming solution capable of supplying foaming solution to the emulsifier apparatus within a range of selected pressures. The foam outlet is connected to a discharge conduit supplying foam to a gas well. The production of foam is initiated out of the foam outlet of the emulsifier apparatus by supplying compressed air to the emulsifier apparatus through the compressed air inlet at a rate of approximately 300 to 400 c.f.m. and at pressures within a range of 175 p.s.i and 375 p.s.i. and foaming solution is supplied to the emulsifier apparatus through the foaming solution inlet at a rate of approximately 10 to 15 liters per minute and at pressures sufficient to overcome internal pressure within the emulsifier apparatus caused by the inflow of compressed air through the compressed air inlet. The pressure of compressed air supplied to the emulsifier apparatus through the compressed air inlet is increased with a corresponding increase in the pressure of foaming solution supplied to the foaming solution inlet until sufficient pressure is generated to force foam exiting the foam outlet along the discharge conduit and down the gas well with an average density of approximately 1 KPA per meter, while monitoring gas well pressure and varying compressed air pressure and foam density to ensure that pressure is always maintained at less than 80% of well pressure.
