The water-conserving liquid ring vacuum pump system receives the output from a water ring vacuum pump, removes the air and contaminants from the water, and returns the clean water to the make-up water port on the pump, thereby saving most of the water that would normally be discarded. Friction in the pump also heats the water, so the system is designed to cool the water as well.

Disclosed is a component-replaceable water ring vacuum pump in which inner components within a head unit may be disassembled and replaced without separation of the head unit from a main body, thus shortening an operation time and improving operation efficiency through prevention of leakage of an inner liquid during a replacement process. The water ring vacuum pump includes a main body provided with a shaft, a rotor rotated together with the shaft within the main body, a head unit coupled to both sides of the main body, a guide bearing provided within the head unit, and a mechanical seal configured to block inner gas. A bearing bracket to support the guide bearing is detachably fastened to one side of the head unit by a bolt, and an inner cap and an outer cap are assembled to the inner and outer surfaces of the bearing bracket by fixing bolts.

Embodiments of the invention are directed toward a novel pressurized vapor cycle for distilling liquids. In some embodiments of the invention, a liquid purification system is revealed, including the elements of an input for receiving untreated liquid, a vaporizer coupled to the input for transforming the liquid to vapor, a head chamber for collecting the vapor, a vapor pump with an internal drive shaft and an eccentric rotor with a rotatable housing for compressing vapor, and a condenser in communication with the vapor pump for transforming the compressed vapor into a distilled product. Other embodiments of the invention are directed toward heat management, and other process enhancements for making the system especially efficient.

A microfluidic pump composed of a cylindrical chamber, transfer ports having an inlet port and an outlet port positioned on the cylindrical chamber, a magnet member attached outside the cylindrical chamber, a magnetic piston in sliding communication with an inner wall of the cylindrical chamber, a magnetic material, and a valve member. The magnetic material self assembles to form a seal plug separating the inlet and outlet port, where the seal plug forms a link between the magnet member and the magnetic piston to rotate the magnetic piston along the inner wall of the cylindrical chamber, where a working fluid suctioned within the cylindrical chamber is discharged at the outlet port during a movement of the magnetic piston from the inlet to outlet port. The valve member positioned at the outlet port prevents the backflow of the working fluid towards the inlet port after the magnetic piston rotates past the outlet port.

The aim of the invention is to significantly increase the electrical efficiency or the proportion of the effective work of gas turbines, even in small gas turbines or microsize gas turbines having a simple design. According to the invention, the drawbacks of the prior art are overcome using wet combustion with oxygen, the oxygen being supplied via mixed-conducting ceramic membranes. The driving force needed for the oxygen to penetrate is created by lowering the partial pressure of the oxygen on the permeate side of the membrane module (5), and the energy required therefor is taken from the process energy produced in the gas turbine process.

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.

A pump includes a housing that contains a liquid, and a rotor including a plurality of blades extending radially from a shaft, and defining a conical space. A port member is disposed within the conical space. The port member defines an inlet port in communication with a low pressure region, a discharge port in communication with a high pressure region, and an anti-cavitation port in communication with a fluid supply having a pressure between the low and the high pressure regions. Each pair of adjacent blades cooperates with the liquid and the port member to enclose a variable volume bucket, wherein rotation of the rotor selectively positions a bucket in an inlet position adjacent the inlet port to draw in fluid, in an anti-cavitation position wherein the bucket is adjacent the anti-cavitation port and fluid is admitted into the bucket, and a discharge position wherein the bucket is positioned adjacent the discharge port to discharge fluid.

Liquid ring pumps are used to pump a variety of fluid types. The present invention provides a two stage liquid ring pump through which an exhaust gas comprising compounds to be destroyed is passed. The exhaust gas passes through the first stage to a gas abatement device, following which it is passed back to the second stage of the liquid ring pump for removal of the compounds formed in said abatement device. The stages of the liquid ring pump may be adjustable.
