4results about How to "Improve gas-liquid separation efficiency" patented technology

The present application relates to wastewater treatment technical field, specifically provide a kind of methylcyclohexane diamine production waste liquid treatment equipment and process, equipment includes heat exchanger, gas-liquid separator, fluid conveying assembly and annular flow guide, heat exchanger has mutually isolated and can be mutually heat exchange first fluid passage and second fluid passage;Gas-liquid separator is located above heat exchanger.The present application by making waste liquid in the outlet direction of gas-liquid separator upward, and annular flow guide is set above the outlet of waste liquid, so waste liquid flows out upward and boils after decompression, under the flow guiding effect of annular flow guide, gas phase and liquid phase are dispersed, reduce the interaction between gas phase and liquid phase, so compared with the technical scheme of waste liquid outlet direction downward in prior art, the distance of gas phase downward movement will be shorter, so it is advantageous to improve the gas-liquid separation efficiency of waste liquid.

This utility model relates to the field of household appliance technology, and discloses a steam generator and cooking appliance. The steam generator includes a water tank, a heating element, a water-blocking element, and an impeller assembly. The water tank has a cavity, and the heating element is disposed on the water tank. The water-blocking element includes a water-blocking plate, which is positioned below and close to the high water level line of the water tank, allowing fluid below the water-blocking plate to pass over it. The water is heated into steam and rises in gaseous form until it overflows the liquid surface. The function of the water-blocking plate is to puncture large air bubbles into smaller ones and increase water resistance, thereby preventing water droplets from splashing to the steam outlet, thus achieving stable separation of water and steam.

The invention discloses a spiral-wound membrane assembly, gas-liquid separation equipment and a gas-liquid separation method.The spiral-wound membrane assembly comprises a membrane unit and a central pipe, one side of the membrane unit is connected with the central pipe, and the membrane unit sequentially comprises a first membrane, a first flow guide net, a second membrane and a second flow guide net outwards from the face attached to the central pipe; gas flow channels are respectively formed between the first diaphragm and the second flow guide net and between the second diaphragm and the second flow guide net; a raw water flow channel is formed between the second diaphragm and the second flow guide net; a collecting hole is formed in the outer circumferential face of the center pipe and communicates with the gas flow channel, and a spiral groove is formed in the inner circumferential wall of the center pipe in the axis direction. To-be-treated liquid flows through the raw water flow channel from the water inlet port; under the driving of gas phase side pressure difference, gas in the liquid to be treated penetrates through the first diaphragm, the second diaphragm and the first flow guide net and enters the gas flow channel; and gas enters the central pipe through the collecting holes and is discharged. According to the spiral-wound membrane assembly, the permeation side flow resistance is reduced, and the permeation flux and the separation efficiency are improved.

The utility model discloses a combined gas purification coalescer, including the casing, be provided with the cylinder in the casing, be provided with centrifugal unit between cylinder and casing, the inside of cylinder is provided with the filler unit and microfiltration unit from below to top, and the gas of entering the casing is purified in proper order through centrifugal unit, filler unit and microfiltration unit, finally discharges through the export of cylinder top, in the application, through setting centrifugal unit to drive the gas movement of entering the casing through the realization gas -liquid spin -off of centrifugal effect, and centrifugal unit is located between cylinder and casing, and the gas of being handled through centrifugation is convenient to contact casing bottom wall after upward movement and enter the cylinder, and realize repeated filtration through filler unit and microfiltration unit in proper order, and gradually filter separation of liquid and other impurities in the gas, thereby improve the gas -liquid separation efficiency of coalescer through combined structure, reach the purpose of energy -conserving, reducing consumption, increasing yield, increasing efficiency.
