Description

FIELD OF THE INVENTION
A compressor with a movable flexible membrane can be used in an industrial refrigeration cycle during condensation of a refrigerant, in a steam heating cycle, where, when water or other liquid substance is supplied under pressure to the lower compartment of a compressor, saturated water vapor is compressed, partially condensed and partially condensed and heated during condensation or other medium. Also, a compressor with a movable flexible membrane can be used as a pump in the thermal cycles of a thermal power plant, in the evaporation and distillation cycles of a liquid, where steam pressure is also used to displace and pressure the liquid through pipes for long distances and heights.
State of the art
A known membrane compressor (description of the invention is contained in USSR author's certificate No. 1657741 A1), comprising a housing made in the form of disks interconnected at the periphery and provided with valve blocks, a bimetallic membrane pinched between the disks consisting of two layers of different metals, the membrane equipped with an element forming a thermocouple with the first layer facing it, and the membrane and the element are connected to the terminals of the AC voltage source, while in order to increase the efficiency and reduce the size ritov element is a layer covering the membrane and the second membrane layer is made of the same material as the element, wherein the membrane is connected to the terminal via the second layer. In a membrane compressor, when voltage is applied to the terminals, on two surface junctions, layers of a bimetallic membrane, heat is sequentially generated and absorbed, while the layer on which heat is released expands and increases in size, and the opposite layer narrows and decreases in size, resulting in a membrane bends towards the layer on which heat is released. The disadvantages of a membrane compressor include significant electricity costs for sequential thermal expansion and contraction of junctions, layers of a bimetallic membrane and a limited useful working volume, which can be used during membrane oscillations in the processes of absorption and injection of a gas or gas-vapor medium inside the compressor.
Known pumping system (the invention is described in the RF Patent No. 2519681 C2), designed to supply suspensions. The pump system contains two pressure vessels, a pump alternately supplying water through the pipeline to the chambers, a suspension pipeline through which the suspension flows from each pressure vessel alternately when its chamber expands, and a control device that supplies water to one chamber shortly before full compression of the other and vice versa. At the same time, each of the pressure vessels contains an internal elastic chamber. The disadvantage of this invention is the need for significant cyclic expansion and narrowing of the size and volume of the elastic chambers, accompanied by contact and friction against the walls of the pressure vessels with significant changes in water pressure, which, ultimately, can lead to rapid wear and tear of the elastic chamber.
A device for pumping a fluid medium (the invention is described in the RF Patent No. 2545116 C1), containing a sealed chamber, which is installed with the possibility of joint and simultaneous displacement and suction of the pumped medium working body in the form of a toroidal elastic shell having an elastic filler, and also equipped with a piston, and a drive made in the form of a drum associated with an electric motor, and roller blocks, and a toroidal shell mounted on a piston, on both sides of which is fixed ibkaya connection passing through the seal mounted at the ends of the chamber, roller units and the drum, and in a chamber at its ends mounted for interaction with the working body of limit switches connected to the motor. In this case, the elastic filler of the toroidal elastic shell is made in the form of a non-fluid toroidal liner, the surface of which has an antifriction coating, and in the idle state, the thickness of the liner exceeds the gap between the piston and the inner wall of the sealed chamber. The disadvantage of this invention is that with significant pressure differences in the sealed chamber between the displaced and suctioned working medium separated by a piston and a toroidal elastic shell, serious deformation of the elastic shell is possible, leading to a pressure loss in the displaced working medium or, in the case of significant and rapid deformation , to rupture of the toroidal elastic shell.
Known membrane car of volumetric action (the invention is described in the RF Patent No. 2491446 C2), comprising a housing with a working chamber connected to the suction and discharge valves, a rod and pinched in the housing, and cavities on the membrane membrane, which are filled with an incompressible, mobile medium. In this case, the cavities between the membranes are closed, and the membranes have the same deflection. In a working membrane machine, with the reciprocating movement of the rod through the working chamber, successively opening and closing, the suction and discharge valves, fluid is pumped. At the same time, with the translational movement of the rod under the pressure of the pumped liquid, the membranes are deformed by the same amount, evenly distributing the pressure among themselves, until the total force from the deformation of each membrane balances the fluid pressure. Further, the pressure of the elastically deformed membranes is transferred to the liquid during its displacement and pressure output through the discharge valve. The disadvantage of a volumetric membrane machine is the limitation of the volume of displaced liquid, the magnitude of the deflection deflection of the membranes, and the increase in the time range of liquid displacement due to the addition of time, which is additionally spent on the deformation of all membranes.
Closest to the proposed invention is an invention, an automatic reckless water pump (the invention is described in USSR author's certificate No. 138818) including a water boiler with an elastic chamber separating water and air and an electric pump unit with the necessary automation. In this case, the elastic chamber is made in the form of a cylindrical can, the neck of which is sandwiched between the annular conical surfaces of the lid and hatch of the water-air boiler. The disadvantage of this invention is the need for significant cyclic expansion and narrowing of the size and volume of the elastic chamber, when the water is supplied by an electric pump unit, which is accompanied by significant changes and pressure drops inside the water pump, and ultimately can lead to rapid wear and tear of the elastic chamber.
The implementation of the invention
The objective of the invention is to provide a compressor with a movable flexible membrane, which, to a large extent, eliminates the above disadvantages arising from the operation of machines, compressors, pumping systems and pumping devices containing membranes and elastic chambers, and in which the service life should be increased , compared with the above devices of the same performance.
This problem is solved as follows. A compressor with a movable flexible membrane contains a thermally insulated spherical casing, devices and pipes for supplying and discharging steam, devices and pipes for supplying and discharging a liquid medium, for example, water, a device and a pipe in the central part of the casing for discharging liquid condensate generated by the compression of steam, a flexible heat-insulating and waterproofing partition, a membrane that divides the inner part of the spherical body into two insulated parts, the upper one into which steam is supplied and discharged through the pipe, and the lower one into which tube set is supplied and discharged from the bottom a liquid medium. At the same time, the cut of the waterproofing partition, the membrane provides for three layers, the upper and lower waterproofing and heat-insulating layers, and the central reinforcing layer, made of flexible and wear-resistant material, which, when external pressure is transmitted, expands, practically without expanding, repeating in shape the inner surface of the upper or lower hemispherical part of the body. The materials from which the flexible membrane is made, the partition can be interconnected, by flashing, as well as by thermal or chemical bonding, and must meet the requirements of increased strength, wear resistance and heat resistance in predetermined temperature conditions. So when using a flexible membrane, partitions in the temperature ranges from 0 to 200 degrees Celsius, this membrane can be composed of a central reinforcing layer, heat-resistant and wear-resistant Nomex aramid fabric, covered with upper and lower waterproofing and heat-insulating layers of heat-resistant silicone rubber. When using a flexible membrane, partitions in the temperature ranges from minus 40 to plus 80 degrees Celsius, the membrane can include a central reinforcing layer made of wear-resistant high molecular weight Daynem polyethylene fabric coated with upper and lower waterproofing and heat-insulating layers of wear-resistant rubber or other material.
At the same time, the compressor with a movable flexible membrane is also characterized in that it includes the following elements. A system of fasteners that fasten the edges of a flexible membrane, partitions on the horizontal inner part of the body. The case of the upper vertical cylindrical tank with a system of guide mounts and block mechanisms, which allows the flexible membrane, the partition to move only in a given vertical direction. Bearing heat-resistant lifting block, mounted on top of a vertical cylindrical tank, which compensates for the total weight of the flexible membrane, partitions. A horizontal horizontal circular partition located in the central part of a flexible membrane, partition, with cylindrical, upper and lower rings with an angular chamfer installed on it, in which cylindrical, horizontal upper and lower rings with an angular chamfer, can rest on the upper and lower grooves inside the spherical housings in places of docking with pipes for supplying and discharging liquid and steam, compensating for pressure differences and preventing the rupture of a flexible membrane. Fluid drainage holes located on the horizontal lower ring with an angular chamfer, which allow the removal of fluid residues from the gap between the inner lower part of the body and the flexible membrane, the partition with the translational displacement downward of the flexible membrane, septum. The indicated design features of the compressor with a movable flexible membrane make it possible to realize, with a sufficiently high efficiency, successive cycles of lowering and increasing the vapor pressure for displacing and pressure supplying the liquid medium located at the bottom of the compressor, or successive cycles of decreasing and increasing the pressure of the liquid medium for compression condensation and heating of steam located in the upper part of the compressor. At the same time, the method of manufacturing and fastening and the very shape of a durable and flexible membrane, the partition, at which it is moved up and down without expanding under the influence of external pressure, tightly compressing the inner hemispherical upper or lower surfaces of the housing, allows you to expect a significant service life of the flexible membrane , partitions, and, accordingly, the compressor with a movable flexible membrane.

Disclosure of invention
A compressor with a movable flexible membrane contains an upper hemispherical part of the casing 7, with a hole in the center, above which a hermetically closed and insulated horizontal round wall is mounted on top of the casing, an upper vertical cylindrical container 14, a lower hemispherical part of the casing 8, with an opening in the center, under which a lower pipe 10 is fixed to the housing, used for supplying and discharging liquid medium, thermal insulation of the upper part of the housing 1, thermal insulation of the joints between the upper and lower parts of the housing 2, thermal insulation ju of the lower part of the housing 9, thermal insulation of the upper vertical cylindrical tank 3, thermal insulation of the lower pipe 11 connected to the upper vertical cylindrical tank 14, a pipe for supplying and discharging steam 4, an electromagnetic valve 6 connected to the base of the upper hemispherical part of the housing 7, and with the pipe for drainage of condensate 5, fixed with threaded connections 24, for example, with screws, at the edges, on the lower hemispherical part of the housing 8, and on the upper hemispherical part of the housing 7, support racks 12. An essor with a movable flexible membrane is characterized in that the upper hemispherical part of the housing 7 and the lower hemispherical part of the housing 8, at the edges, around their base, have radial fillets without sharp protrusions, turning into horizontal upper and lower flange joints, which clamp the side edges from above and below flexible membranes, partitions 15, and are interconnected using vertical threaded fasteners 13, for example, nuts and bolts secured between the upper and lower flange joints, while the flexible membrane on, the partition 15, in the expanded state in shape, repeats the inner surface of the upper hemispherical part of the housing 7, and the lower hemispherical part of the housing 8, and includes a reinforcing layer with a hole in the center, from a flexible heat-resistant and wear-resistant material 26, for example, from aramid fabric, on which the upper and lower waterproofing and heat-insulating layers of the flexible membrane 25 are fixed, combined with the hole in the center and fixed and waterproofed using vertical fasteners 29, for example, using two rivets, and rubber gaskets 30, a horizontal circular partition 16 on which the following elements are fixed, vertical rods 17 are welded or fixed on top, and a horizontal upper ring with an angular bevel 27, the outer diameter of which is larger than the inner diameter of the upper vertical cylindrical container 14, a horizontal lower ring with an angular chamfer 28 welded or fixed below, the outer diameter of which is larger than the inner diameter of the lower pipe 10, used for supply and removal liquid medium, and the lateral surface of which contains horizontal holes 31. In this case, the vertical guide rods 17 are connected by upper ends to heat-resistant flexible cables 18 and are held in an upright position by means of horizontal rings with cylindrical guide holes 19 that are mounted on horizontal posts, connected to the upper vertical cylindrical tank 14, in turn, heat-resistant flexible cables 18 are elastically stretched, suspended vertically and pass through the bearing term a stable lifting unit 20, fixed with a fastener 21, from above in the center of the horizontal round wall, on the inner surface of the upper vertical cylindrical tank 14, and connected at one end to the fasteners 22, on which the suspended load 23 is held, the second of the ends with the guide rods 17. It can also be noted that the flexible membrane, the septum 15, can be compressed with a seal of the upper and lower waterproofing and heat-insulating layers of the flexible membrane 25, at the junctions with the upper hemispherical part Tew housing 7 and a lower hemispherical part of the housing 8 by a vertical threaded fasteners 13, as shown in FIG. 5, to obtain high-quality waterproofing between the upper hemispherical part of the casing 7, and the lower hemispherical part of the casing 8. Similarly, to obtain high-quality waterproofing at the joints with the horizontal circular partition 16, the flexible membrane, the partition 15, can be compressed using vertical fasteners 29, as shown in FIG. 6. As previously indicated, for a compressor with a movable flexible membrane, two modes of operation and functioning can be provided, the first as a compressor for compressing steam or gas, the second as a pump designed for pressure supply of liquid.
When operating as a compressor when compressing steam or gas, a compressor with a movable flexible membrane can be used, for example, to compress, partially condense and heat saturated water or other steam, where the water used to compress the steam is supplied under high pressure to the lower part compressor with a movable flexible membrane, with hydraulic structures located in the mountains. In this mode, the operation of the compressor with a movable flexible membrane can be carried out as follows. The lower pipe 10 will be connected through electromagnetic valves to a pressure fluid supply system, for example, to a hydraulic structure, including a reservoir or other water body, the water level in which is significantly higher than the maximum level to which a horizontal circular partition 16 can be raised, and with a drainage system liquids, for example, with a channel or other water body, the water level in which is significantly lower than the minimum level to which a horizontal circular partition can be lowered 16. In the first stage, liquid is discharged through the lower pipe 10, accompanied by a sharp drop in pressure in the lower part of the compressor under a flexible membrane, while saturated vapor is supplied to the upper part of the compressor under a given pressure, displacing the flexible membrane, baffle 15, down, from the upper end position to FIG. 3 to the intermediate position shown in FIG. 2, and then to the lowest position shown in FIG. 4. In this case, the remaining water between the lower hemispherical part of the housing 8, and the flexible membrane, the baffle 15, which falls on its inner surface, can be diverted into the lower pipe 4, through horizontal holes 31 located in the horizontal lower ring with an angular chamfer 28. At the second stage, the electromagnetic valve is temporarily closed, through which steam is supplied through the pipe 4, the electromagnetic valve connecting the lower pipe 10 is also closed, with the liquid drainage system, and second solenoid valve connecting the lower pipe 10, the pressure fluid supply system. During its operation, the adjustable solenoid valve gradually opens, which makes it possible to smoothly increase the pressure inside the space between the lower hemispherical part of the housing 8 and the flexible membrane, the partition 15, and protect these items of equipment from water hammer. The liquid supplied under pressure through the lower pipe 10 lifts the flexible membrane, baffle 15, up to a certain intermediate level, compressing, condensing and heating the saturated vapor above the flexible membrane, baffle 15. Next, the solenoid valve opens, connected to the pipe 4, through which the heated and compressed to the required density steam is diverted for further useful use. The displacement of heated and compressed steam occurs during the lifting of the flexible membrane, the septum 15, under the pressure of the liquid, from intermediate to the highest level shown in FIG. 3.
In this case, condensate formed during the compression of saturated steam and flowing into the area between the base of the upper hemispherical part of the housing 7 and the partially raised flexible membrane, the baffle 15, can be diverted through the condensate drain pipe 5, when the electromagnetic valve 6 is opened 6. Next, the cycle repeated, the electromagnetic valve associated with the fluid drainage system is opened and the flexible membrane, baffle 15, moves down again. It can also be noted that when displaced upward using a flexible membrane, septum 15, heated and compressed steam, a small amount of this steam remains in the upper vertical cylindrical tank 14, and can then be used in the first stage in the next cycle of the compressor with movable flexible membrane, to displace and increase the speed of translational downward movement of the flexible membrane, partitions 15. When operating the compressor with a movable flexible membrane, also used mounted on a horizontal circular partition 1 6, a horizontal upper ring with an angular chamfer 27, and a horizontal lower ring with an angular chamfer 28, which, with a maximum upward and downward displacement of the flexible membrane, partitions 15, are successively supported from the inside by niches located in the upper hemispherical part of the casing 7, the lower hemispherical part of the casing 8 , compensating for pressure differences and preventing tears in the Central part of the flexible membrane, the partition 15. In this case, in this mode of operation, the use of a heat-resistant bearing block, with upward displacement and of suspended load 23, which is fixed to the top vertical cylindrical container 14, to compensate for a predetermined overweight flexible membrane, the partition 15, and implement operation of the compressor with a movable flexible membrane with a slightly larger overall efficiency.
When working as a pump designed for pressurized liquid supply to a compressor with a movable flexible membrane, steam is pumped in the liquid displacement cycle under pressure, which is then diverted, in the liquid supply cycle, to the lower part of the compressor with a movable flexible membrane. At the same time, if the steam discharged from the pump is not discharged, but is useful, for example, in the compartments of a multi-stage evaporator, entering its compartments and giving its heat to evaporate water, this steam removal mechanism can be considered as intermediate, working with good efficiency in the general scheme evaporation and distillation of water. In this mode, the operation of the compressor with a movable flexible membrane is as follows. A pipe for supplying and discharging steam 4, connected to a steam supply and removal system, for example, to a system that includes a steam injection, steam boiler and exhaust steam, a multi-stage evaporator, undergoes a cyclic pressure change in the upper part of the compressor with a movable flexible membrane. At the first stage, steam is discharged through the pipe 4, and in the upper part of the compressor above the flexible membrane, the baffle 15, the vapor pressure gradually decreases and becomes less than the external atmospheric pressure. In this case, the flexible membrane, the partition 15, is initially pressed from the inside to the lower hemispherical part of the housing 8, as shown in FIG. 4, under the pressure of the liquid coming from the open reservoir through the lower pipe 10, displacing the steam, gradually rises to the intermediate position indicated in FIG. 2, and then is pressed from the inside to the upper hemispherical part of the housing 7, as indicated in FIG. 3. In the process of lifting the flexible membrane, the partition 15, there is a gradual rise of the vertical guide rods 17, rigidly fixed to the horizontal circular partition 16, and the vertical displacement, from top to bottom, of the suspended load 23 suspended on the heat-resistant flexible cables 18. Moreover, during movement guide vertical rods 17, prevent lateral displacements of the horizontal circular partitions 16, sequentially passing through horizontal rings with guide cylindrical holes 19, and shifting upward with unified with rods 17, heat-resistant flexible cables 18. When lifting to maximum height, a horizontal upper ring with an angular chamfer 27 fixed on a horizontal circular partition 16 is pressed from the inside to a niche located in the upper hemispherical part of the housing 7, which prevents tearing in the central part of the flexible membranes, septa 15.
In the second stage, when the lower part of the compressor under the flexible membrane, the partition 15, is completely filled with liquid, the movement of liquid from the open tank to the lower pipe 10 is blocked by an electromagnetic valve, and an electromagnetic valve is opened through which the liquid through the lower pipe 10 can under the pressure is fed through pipes over long distances and heights. To ensure greater functional reliability and durability of a compressor with a movable flexible membrane, the supply of high-pressure steam generated by an external system may include the use of an electromagnetic valve that is adjustable and opens at a given speed and allows a smooth increase in pressure in the upper vertical cylindrical tank 14, and then inside the space between the upper hemispherical part of the housing 7, and a flexible membrane, the partition 15. After passing the adjustable upper electr of the solenoid valve, steam through the pipe for supplying and discharging steam 4, is pumped into the upper vertical cylindrical tank 14, moves down the horizontal circular partition 16, and starts at a given pressure, which can exceed 1.5 MPa, and when the solenoid valve is open connected to the pressure with the outlet pipe, lower the flexible membrane, the baffle 15, down to the intermediate position shown in FIG. 2, and further, to the extreme position shown in FIG. 4. In the process of moving downward, the guide vertical rods 17 prevent lateral displacements of the horizontal circular partition 16 by passing through horizontal rings with guide cylindrical holes 19, and shifting downwardly connected to the rods 17, heat-resistant flexible cables 18. At the same time, at maximum downward displacement of the flexible membrane, septum 15, mounted on a horizontal circular partition 16, the horizontal lower ring with an angular chamfer 28, is pressed from the inside to a niche located in the lower hemisphere part of the housing 8, which prevents breaks in the Central part of the flexible membrane, the partition 15. Appears, when the steam is injected into the upper part of the compressor, as a result of the useful work of the steam, and also as a result of heat loss through the walls and through the flexible membrane, the partition 15, small the amount of condensate can be removed from the pump, when the flexible membrane, the septum 15, is in the intermediate position, using the condensate drain pipe 5, when the electromagnetic valve 6 shown in FIG. 1 and FIG. 2. Next, the second stage ends, and a new, repeated cycle of steam removal from the upper part of the compressor and supply of liquid to the lower part of the compressor begins, as part of the first stage of the compressor with a movable flexible membrane. At the same time, the use of a heat-resistant bearing block mounted on the upper vertical cylindrical tank 14, with the suspended load 23 moving up and down, allows you to compensate for the specified excess weight of the flexible membrane, the partition 15, and to supply fluid with a slightly higher overall efficiency.
