A fluid processing apparatus includes: a casing having a fluid inlet pipe and a fluid outlet pipe; multiple rectifying plates with holes in parallel with each other provided within the casing on a side of the fluid inlet pipe, the rectifying plates being perpendicular to a longitudinal axis of the casing; and a light source for irradiating fluid passing from the fluid inlet pipe through the casing to the fluid outlet pipe with ultraviolet rays.

Delivery systems for in situ forming foam formulations are provided. The devices may include various actuation mechanisms and may entrain air into fluid formulation components in a variety of ways, including mixing with air and the addition of compressed gas.

It is an object of the present invention to provide a fluid stirring and liquefaction promoting apparatus which enables uniform mixture of refrigerator oil with refrigerant, thereby improving the heat exchange efficiency of heat pump systems and reducing the energy consumption. There is provided a liquefaction promoting apparatus to be disposed on a pipeline of a heat pump system for the purpose of stirring and uniformly mixing the fluid containing refrigerant and refrigerator oil circulating therein. The apparatus comprises a cylindrical casing, an one or more channelizing units each composed of a pair of large-diameter disks on its outer side and a pair of small-diameter disks on its inner side disposed in axial alignment inside the cylindrical casing. Each of the large-diameter disks is on its inner surface with a honeycomb panel having polygonal cells and each of the small-diameter disks is formed on its outer surface with a honeycomb panel having polygonal cells such that the honeycomb panels of the large-diameter disks and of the small-diameter disks are arranged to face each other and each polygonal cell communicates with more than one opposing polygonal cells. The fluid containing refrigerant and refrigerator oil is circulated in the heat pump system with a pressure of 0.2 to 10 MPa.

The present invention relates to methods and systems for producing a foamed adhesive. A method for foaming an adhesive includes feeding an adhesive from a supply storage tank to a pump, conveying the adhesive outputted by the pump through an adhesive flow meter, injecting an air into the adhesive once the adhesive travels through the adhesive flow meter, feeding a mixture of the adhesive and air to a static mixer, mixing the mixture homogeneously with the static mixer such that the adhesive is foamed, and transporting the foamed adhesive to a product storage tank.

A bubble splitter, which is arranged for splitting gas bubbles in a bubbled liquid in at least a micro size, includes a splitting housing, a plurality of first splitting discs, and a plurality of second splitting discs. The first and second splitting discs are alternating with each other to be spacedly supported within the splitting housing, wherein a plurality of peripheral passages are formed at peripheral portions of the first splitting discs respectively and a plurality of central passages are formed at center portions of the second splitting discs respectively. The bubbled liquid is detoured to radially and outwardly move from the central passage to the peripheral passage and is detoured to radially and inwardly move from the peripheral passage to the central passage so as to split the gas bubbles in the bubbled liquid in at least a micro size.

Microstructure flow mixing devices are disclosed herein. An example device a first panel, a first plurality of raised features extending from a first surface of the first panel, a second plurality of raised features extending from the first surface of the first panel and a plurality of divider microstructures extending from the first surface of the first panel in line with and in between the first plurality of raised features and the second plurality of raised features. At least a portion of adjacent divider microstructures are spaced apart to form feed pathways or cross channels.

A gas dissolution accelerating device with a simple structure efficiently increases the concentrations of oxygen dissolved in deep water, such as at lake bottoms. A gas dissolution accelerating device includes a cylindrical member located parallel to a vertical direction when installed, a box member having an opening facing downward when installed, and a fixing unit for fixing the box member to a diffuser. The box member includes a top plate having a cone-shaped protrusion protruding inward and a through-hole receiving the cylindrical member. The fixing unit includes a flat attachment plate having an upper surface onto which the box member is mounted, a pair of halved banding members for clamping a feeding pipe of the diffuser, and rod-shaped connecting members connecting the attachment plate to the banding members.

A mixing unit includes a mixing body having mixing elements that are stacked in a stacking direction and that extend in an extending direction in which the extending direction is perpendicular to the stacking direction. The mixing elements have a plurality of through holes to form a flow path therein, and are arranged such that part or all of the through holes in one of the mixing elements communicate with through holes in the adjacent mixing elements to allow fluid to be passed in the extending direction in which the mixing elements extend. The mixing unit may be employed in an agitation impeller or an adhesive dispensing unit.

An oily smoke purification device includes a holder, a main housing, a mixing mechanism, a filter and an exhaust fan. The holder is filled with purification solution, the exhaust fan is started to cause a negative pressure inside the main housing, oily smoke enters the purification solution from a gap between the holder and the main housing and is mixed with the purification solution under an action of the mixing mechanism to absorb dirt in the oily smoke into the purification solution, and the oily smoke is filtered by the filter to generate clean air which is sucked by the exhaust fan. The hazardous substance including oil, dust and other impurities in the contaminated air is filtered and the air is purified, thereby protecting the environments and ensuring the heath of people.

The present disclosure relates to a mixer device having a housing including at least first and second adjacent mixing cells (2, 3), each cell (2, 3) including a fluid inlet opening (21, 31) and a fluid outlet opening (22, 32), the inlet opening being offset from the outlet opening so that the axis of the inlet opening is parallel to the axis of the outlet opening, the outlet opening of the first cell being connected to the inlet opening of the second cell via a connecting channel.
