Description

Technical Field

[0001] The utility model relates to a device which utilizes the original energy of natural water flow to lift water from a low position to a high position, in particular to a natural energy liquid-gas pressure water lifting device based on pure water hydraulic transmission technology for pressurization. Background Art

[0002] my country's terrain features more mountains and fewer plains. There is a widespread problem of insufficient water supply in mountainous areas, and it is difficult to use water for production and life in many places. Although there are rivers in many mountainous areas and streams in the gullies, in most cases the water flows down the mountain, and there is a serious shortage of water in the mountains. To be precise, these places are not without water, but the water source is at a low level, and the water-using place is at a high level. The difference in altitude between the two is large, and the altitude difference in some places is hundreds of meters or even thousands of meters. If the currently commonly used electric motor and diesel engine oil are used to drive the water pump, the cost of water use is very high and cannot meet the needs of production and life at all. Therefore, how to economically and conveniently send low-level water to water-scarce areas in mountainous areas is a topic that needs to be solved urgently. Since the problem of water shortage is common in mountainous areas in my country, solving this problem has significant social and economic benefits.

[0003] In order to solve this problem, in recent years, some water-lifting technologies and methods have emerged based on the use of the natural energy of natural water flow, combining hydraulic and pneumatic technologies. Since the entire water-lifting process consumes the natural potential energy of high-level power water, it does not require the provision of additional electricity or the consumption of resources such as oil and coal, so it is called natural energy water-lifting. For the sake of convenience, it will be referred to as "traditional natural energy hydraulic and pneumatic water-lifting technology" below, and its structure and principle are briefly described as follows. According to the information, see Figure 7 The basic principle of the natural energy liquid-gas pressure water lifting technology currently in use is: use a water barrier ⑥ to block water, and divert the power water ⑧ at a high position as power through a water diversion pipe ④ to a lower place. An air inlet ⑤ is provided above the pipe, and the negative pressure generated by the high-speed flowing water is used to suck air into the pipe and mix it with water. The flowing water carries the air downward. When the flowing water reaches the low-level gas-liquid separation chamber ①, the flow rate decreases, the water pressure increases, and the air is separated from the water and floats up, thus forming high-pressure air. The water after gas separation flows out from the drainage pipe ②. The high-pressure air enters the gas-liquid pump ⑦ through the gas transmission pipe ③. At this time, the high-pressure air is used as power to press the low-level water source water through the gas-liquid pump through the water transmission pipe ⑨ to the high-level destination water pool ⑩, thus completing the whole process of water lifting. From the perspective of energy conversion, this type of device converts the potential energy of the high-level power water into the pressure energy of the inhaled air. When the high-pressure air presses the water from the water source to the destination water tank, the pressure energy of the air is converted back into the potential energy of the water.

[0004] The patent application number 201320224475.X of "Continuous water lifting device for head difference pressure conversion" disclosed in the Chinese patent literature introduces a similar water lifting device, but it has the problems of low energy utilization efficiency and small water lifting head.

[0012] For water-lifting projects, there are two most basic indicators: the amount of water lifted and the head of water lifted. The amount of water lifted by natural energy liquid-gas pressure water-lifting technology depends on the volume of high-pressure air, while the head of water lifted depends on the pressure of high-pressure air. How to obtain as much high-pressure air as possible and increase the pressure of high-pressure air is the key to the success of the system. According to the requirements for improving the basic indicators of water-lifting projects, the traditional natural energy liquid-gas pressure water-lifting technology currently in use has the following problems:

[0013] 1. Low efficiency of liquid-gas energy conversion

[0014] According to the principle of energy conservation, after the drainage power water reaches the gas-liquid separation chamber, high-pressure air and high-pressure water are generated at the same time. Ignoring the energy loss caused by the internal friction of the pipeline and the gas-water mixed flow during the drainage process, it should meet the following requirements:

[0015] Dynamic water potential energy = high pressure air pressure energy + high pressure water pressure energy

[0016] ·····························(I)

[0017] When using natural energy liquid-gas pressure water extraction technology to extract water, the pressure energy of high-pressure air is used to do the work of water extraction. However, in the process of water extraction with traditional natural energy liquid-gas pressure water extraction technology, in addition to the pressure energy of high-pressure air being utilized, all the pressure energy of high-pressure water in the gas-liquid separation chamber is lost in vain, thereby reducing the utilization rate of power water energy. This results in a reduction in the effective energy that can be directly used when the power water flow rate is constant, which will inevitably affect the water extraction index.

[0018] 2. Water lifting problem

[0019] According to the basic principles of fluid mechanics, the high-pressure air pressure generated by the natural energy hydraulic water-pneumatic water-lifting technology is equal to the water pressure, which depends on the drainage drop of the power water (hereinafter referred to as the power head, denoted as H):

[0020] P=ρgH······························(II)

[0021] Since the pressure of high-pressure air is equal to the pressure of high-pressure water, ignoring the pipeline loss, and denoting the water lifting head as h, we have:

[0022] P=ρgh=ρgH·················(Ⅲ)

[0023] According to equations II and III, under ideal conditions: h = H·················(Ⅳ)

[0024] Considering that there will inevitably be energy loss in the water lifting process, if the high-pressure air is used directly to lift water without secondary pressurization, the water lifting head h will inevitably be less than the power head H. Due to this limitation, such a head cannot meet the water supply demand in many cases. In order to achieve high-lift water lifting with a lower power head, a question arises about how to pressurize the high-pressure air. How to increase the pressure? What equipment is used for pressurization? Where does the power to drive the supercharging device come from? The purpose of this utility model is to solve the above problems.

[0025] The basic principle of the utility model is to guide the high-level power water to a lower level through a pipeline, and use the negative pressure generated by the high-speed flowing water to suck air into the water pipe and mix it with water. The flowing water carries the air downward, and when the flowing water reaches the low-level gas-liquid separation box, the flow rate decreases and the water pressure increases, and the air floats up and separates, thus forming primary high-pressure air in the upper part of the gas-liquid separation box and high-pressure water in the lower part. This high-pressure water is used as the power of the pure water hydraulic transmission to drive the pure water hydraulic driven air compressor to pressurize the primary high-pressure air, and then use the pressurized high-pressure air to drive the air pressure water pump to pressurize the water from the water source to the destination pool located at a high place, thereby realizing a complete water lifting process.

[0026] The utility model can be divided into two basic units according to its functions, wherein the water retaining dam, air intake pipe, drainage water pipe, gas-liquid separation box, high-pressure water pipe, pure water hydraulic driven air compressor, primary high-pressure air pipe, air compressor drainage pipe, main high-pressure air pipe, and main high-pressure air storage tank constitute the gas production unit; the auxiliary high-pressure air pipe, auxiliary high-pressure air storage tank, sub-high-pressure air pipe, water source pool, air pressure water pump inlet pipe, high-lift air pressure water pump, air pressure water pump outlet pipe, and destination pool constitute the water lifting unit. The two units have different functions, independent physical structures, and are located in different positions. The gas production unit is installed at the outlet of the power water diversion pipeline, located at the lowest point of the natural energy liquid and gas pressure device above sea level. The water lifting unit is installed at the water supply source water intake point, and can be located at a different location from the high-pressure air generation unit. The water supply source water intake point is not necessarily at the water retaining dam, and can be a spring or a stream with good water quality higher than the water retaining dam, which can improve the water supply efficiency and water supply quality. The utility model can realize multi-stage water lifting and multi-point water supply.

[0027] In order to ensure the cleanliness of the power water, the gas-liquid separation box of the utility model firstly provides a water inlet filter for primary filtration on the power water inlet pipe, then removes the heavier solid impurities in the water through the sedimentation effect of the internal space of the box body, and finally provides a water outlet filter for fine filtration at the end of the high-pressure water outlet pipe. In order to ensure the safe operation of the gas-liquid separation box and prevent the water tank from overpressure, a safety valve is provided on the top of the water tank body. The present invention is provided with a manual cleaning device for the inner cavity of the box body on the water tank body, and a manhole and a detachable cover plate are provided on the water tank, so that workers can enter the water tank body for cleaning. A sewage outlet and a sewage valve are also provided at the bottom of the water tank body. The cross section of the water tank body can be designed to be circular or rectangular as required. In order to facilitate the automatic control of the gas-liquid separation box, the utility model is provided with a pressure sensor, a pressure gauge, a liquid level meter and a flow meter on the water tank. The gas-liquid separation box has multiple functions such as transfer, storage, voltage stabilization, coarse and fine filtration, sewage discharge, parameter detection and control of high-pressure water and high-pressure air while serving as a container.

[0028] The function of the pure water hydraulic driven air compressor provided in the utility model is to pressurize the primary high-pressure air from the gas-liquid separation box. The body of the utility model is composed of three piston cylinders, with a pure water hydraulic driven power cylinder in the middle and air compression cylinders on both sides. The driving piston and the left and right air compression pistons are connected as a whole by a piston rod. Under the drive of high-pressure water, the driving piston drives the left and right air compression pistons and moves along the axis of the cylinder body at the same time. The piston of this device has two working states: moving to the left and moving to the right. When the piston moves to the limit position of the cylinder body, the reversing valve controls the change of the movement direction. The reversing valve is alternately switched between the left and right positions, and the left and right air compression cylinders alternately compress air, so that compressed air can be continuously generated. The reversing valve in the structural diagram can be selected from electromagnetic reversing valves, electro-hydraulic reversing valves, stroke reversing valves or other types of reversing valves in actual application, which will not affect the performance of the air compressor.

[0029] Compared with the traditional natural energy liquid and gas pressure water pumping device, the core of the utility model is to set up a pure water hydraulic driven air compressor that uses high-pressure water as power to compress the obtained primary high-pressure air again to increase the pressure of the compressed air. Since the high-pressure water pressure energy that was originally wasted is utilized, it not only improves the overall efficiency of system energy utilization, but also increases the pressure of high-pressure air, greatly increasing the water pumping head and water lifting volume, killing two birds with one stone.

[0030] Theoretical basis of the utility model pure water hydraulic driven air compressor: the effective area of ​​the driving piston is S A ; The effective area of ​​the water pump piston is S B ; The high-pressure water pressure input to the drive cylinder is P1; the outlet pressure of the water pump cylinder is P2. If the friction and back pressure resistance are ignored, the force balance equation on the piston is: P1S A =P2S B

[0031] Let the pressure ratio be K, then we can get: (or: P2=KP1)

[0032] The initial setting of this utility model: S A >S B , its boost ratio K>1, so: P2>P1, from this we know that the water pump has its own boost function.

[0033] If the pump head is recorded as h, according to the basic principles of fluid mechanics, it can be written as: P2 = ρgh or

[0034] It can be seen that the head h is proportional to the outlet pressure P2. The higher the outlet pressure, the greater the head. Therefore, the utility model can use a lower water supply pressure to achieve high-head water lifting, which is particularly suitable for mountain water supply projects.

[0035] The high-lift air pressure water pump of the utility model is specially tailored for natural energy hydraulic and air pressure projects in mountainous areas. The utility model uses high-pressure water as the power, and the driving cylinder drives the two chambers of the water pump cylinder to pump water and replenish water alternately. The water is lifted continuously without empty strokes, and the water lifting efficiency is high. The lift of the high-lift air pressure water pump of the utility model is proportional to the pressure of the compressed air and has almost no restrictions. It has the advantages of simple structure, high lift, low price, stable operation, convenient later maintenance, and low failure rate. It is a new type of pure water hydraulic driven high-lift water pump.

[0036] The characteristics of the utility model are: 1. High efficiency of liquid-gas energy conversion and large water lifting capacity. The core of the technical solution of the utility model is to set up a pure water hydraulic transmission air compressor that uses high-pressure water as power. The high-pressure water that was originally wasted is used as power to pressurize the primary high-pressure air. The base number of the available high-pressure air pressure energy is increased, the liquid-gas energy conversion efficiency is improved, and the water lifting capacity is increased. The amount of power water required for the same effective water lifting capacity is small. 2. Increased water lifting head. The utility model uses a pure water hydraulic transmission air compressor to compress the original primary high-pressure air again. The final pressure of the high-pressure air is determined by the parameters of the pure water hydraulic transmission air compressor. The working parameters can be preset and changed according to requirements. It is no longer limited by the power water drainage drop. It can far exceed the power head and greatly improve the water lifting head. In particular, it can be used in occasions with low-head power water sources, and the applicable area is wider. 3. There is a wide range of choices for water supply sources. The water lifting device of the utility model allows the power water source to be separated from the water supply source. The water supply source is not necessarily the power water source, and can be selected according to the on-site conditions. Of course, in order to improve the efficiency of water extraction, the altitude of the water supply source intake point is generally not lower than the altitude of the power water intake point, so that the water lift can be maximized. 4. It can realize multi-point water supply and multi-stage water extraction. If equipped with multiple water extraction units, it can easily realize multi-point water supply and multi-stage water extraction, which has a wider range of applications.

[0056] The structure of the pure water hydraulic driven air compressor (6) is shown in Figure 3 and Figure 4 The specific structure is: the middle of the inner cavity of the composite cylinder body (604) is a power cylinder driven by pure water hydraulic pressure and a left air compression cylinder and a right air compression cylinder are symmetrically arranged on both sides. Since the left air compression cylinder and the right air compression cylinder are unidirectional compression, this embodiment is based on the convention in the technical field. The left air compression cylinder and the right air compression cylinder are provided with ventilation holes that are connected to the atmosphere. The middle of the piston rod is fixedly connected to the power cylinder driving piston (603), the left end of the piston rod is fixedly connected to the left air compression piston (601), and the right end is fixedly connected to the right air compression piston (602).

The reversing valve (613) is an electromagnetic reversing valve, an electro-hydraulic reversing valve or a stroke reversing valve.

[0057] The reversing valve of this embodiment switches alternately between the left and right positions, so that high-pressure water alternately enters or is discharged from the A1 chamber or the A2 chamber of the pure water hydraulically driven air compressor power cylinder. The driving piston drives the left air compression piston and the right air compression piston to reciprocate synchronously, and the primary high-pressure air is alternately sucked into the B1 chamber or the B2 chamber, and output after compression. The pure water hydraulically driven air compressor can continuously generate compressed high-pressure air by working continuously.

[0058] Working principle of pure water hydraulic driven air compressor: When the reversing valve is in the left position, the movement direction of gas, high pressure water and piston is as follows: Figure 3As shown. The high-pressure water from the gas-liquid separation box enters the A1 chamber through the water inlet pipe, passes through the left position of the reversing valve, and pushes the air compression piston, the left air compression piston and the right air compression piston to move right at the same time. The water in the A2 chamber passes through the left position of the reversing valve and is discharged from the drain pipe. At this time, the volume of the B1 chamber is expanded and is in the suction state. The air to be compressed enters the B1 chamber through the air inlet pipe and the left air inlet check valve to replenish air. At the same time, the volume of the B2 chamber is reduced and is in the compression state, and the right air inlet check valve is closed. The compressed air is discharged from the right air outlet check valve and the exhaust pipe and enters the gas storage tank or gas-using equipment. When the reversing valve is in the right position, the movement direction of the gas, high-pressure water and piston is as shown in the figure. Figure 4 As shown. The high-pressure water from the gas-liquid separation box enters the A2 chamber through the water inlet pipe, through the right position of the reversing valve, and pushes the air compression piston, the left air compression piston and the right air compression piston to move to the left at the same time. The water in the A1 chamber passes through the right position of the reversing valve and is discharged from the drain pipe. At this time, the volume of the B2 chamber is expanded and is in the suction state. The air to be compressed enters the B2 chamber through the air inlet pipe and the right air inlet check valve to replenish air. At the same time, the volume of the B1 chamber is reduced and is in the air compression state, and the left air inlet check valve is closed. The compressed air is discharged from the left air outlet check valve and the exhaust pipe and enters the air storage tank or air-using equipment.

[0060] The structure of the high-lift air pressure water pump (16) is shown in Figure 5The specific structure is as follows: the pump body (801) is provided with two parallel working chambers, the devices on the two working chambers are identical and symmetrical, the tops of the two working chambers are provided with air inlet and exhaust ports (802), the air inlet and exhaust ports are connected to the reversing valve (812) through pipelines, the upper parts of the two working chambers are provided with water inlets (804), the water inlet is provided with a water inlet check valve (805) that can only allow water to enter, the two water inlets are connected by pipelines and then connected to the water inlet pipe (810), the lower parts of the two working chambers are provided with water outlets (807), the water outlet is provided with a water outlet check valve (808) that can only allow water to exit, the two water outlets are connected by pipelines and then connected to the water outlet pipe (809), the high-pressure air inlet pipe (811) is connected to the reversing valve (812), the upper parts of the two working chambers are provided with high-level liquid level gauges (803) at positions higher than the water inlets, and the lower parts of the two working chambers are provided with low-level liquid level gauges (806) at positions higher than the water outlets. The reversing valve (812), the high-level liquid level meter (803) and the low-level liquid level meter (804) are connected to the automatic control device. The reversing valve is a two-position five-way electromagnetic valve.

[0061] Working principle of double working chamber high lift air pressure water pump: There are two high and low level gauges in the working chamber of the pump body, corresponding to the high and low water levels respectively. When the water level in the working chamber of the pump body reaches the set high water level, the high level gauge sends a signal, and the electromagnetic reversing valve connects the inlet and outlet ports to the high-pressure air. At this time, the inside of the working chamber of the pump body is in a high-pressure state. Under the action of the upper high-pressure air pressure, the water outlet check valve opens, the water inlet check valve closes, and the water in the working chamber of the pump body flows out from the outlet through the outlet pipe. At this time, it is a water lifting condition. When the water level in the working chamber of the pump body drops to the set low water level, the low level gauge sends a signal, and the automatic control system instructs the electromagnetic reversing valve to reverse, so that the inlet and outlet ports are connected to the atmosphere. At this time, the working chamber of the pump body is in a low-pressure state. Under the low-pressure state, the water outlet check valve is closed, the water inlet check valve is opened, and the water from the water source enters the pump body. At this time, it is a water replenishment condition. When the water level rises to the set high water level, the high level gauge sends a signal, and the automatic control system instructs the electromagnetic reversing valve to reverse, connect the inlet and outlet to the high-pressure air again, and restart the water pumping operation. This cycle can achieve automatic water replenishment and water pumping.

[0062] It is particularly noted that the high-lift air pressure water pump of the utility model adopts two working chambers. When one working chamber is in a water-lifting condition, the other working chamber must be in a water-replenishing condition. The working conditions of the two working chambers cycle alternately. At any time, there is always a working chamber in a water-lifting condition, so uninterrupted water supply can be achieved.
