Electric energy is not only used for lighting, but also used to drive machines, equipment, etc. Water pumps are also one of the electrically driven equipment. In people's production and life, the water pump is an indispensable tool. The function of the water pump is to transport the water from the low position to the high position and increase the potential energy of the water. The current water pump mainly consumes electric energy or fuel oil, which has become an important part of energy consumption.
同时在发电及其他生产活动中产生的烟气、废水等的温度较高，含有较多的热量，如果直接排放到环境中，会造成资源利用率低，浪费能源也危害环境。目前废热的来源主要有电厂的烟气冷凝热、电厂循环水废热以及炼钢、石油化工等工业废热，当今废热的回收利用已得到人们的关注，相应的废热回收技术及装置也得以研究和发展。当前的废热主要用于废热回收发电、废热锅炉、吸收式热泵、供暖等场合，废热水泵的应用较少。At the same time, the flue gas and waste water produced in power generation and other production activities have a high temperature and contain more heat.

该装置的运行分为加热、排水、排汽、冷却、抽水五个阶段，实现自动控制，加热阶段利用废热为加热水箱提供热量，产生的水蒸气通过第一止回阀进入驱动水箱中，此过程中驱动水箱内部的压力大于外部大气压而小于排水压头，则在压差和止回阀的作用下冷却水箱和水源中的水不能进入驱动水箱内，驱动水箱中的水也不能进入到位置较高的贮水箱中，但由于加热水箱进水口位置比驱动水箱排水口低，则驱动水箱内的水可以流回到加热水箱中继续加热蒸发产生水蒸气，保证了加热水箱内水的时刻供应，避免形成干蒸汽带来的隐患；排水阶段当进入驱动水箱的蒸汽增多，驱动水箱内压力大于排水压力时，驱动水箱中的水一部分通过第三止回阀排入贮水箱中，把来自水源的水从位置低的地方输送到位置较高的贮水箱中，另一部分水通过第二止回阀流到加热水箱中，继续由废热源加热产生水蒸气，此排水过程中驱动水箱内的压力较大，水源和冷却水箱内的水不能进入驱动水箱内；排汽阶段在排水过程结束，驱动水箱的水面低于与贮水箱相连的排水口时，加热水箱产生的蒸汽通过驱动水箱排到贮水箱入口处的外部环境中；冷却阶段在蒸汽排到外部环境时，驱动水箱与外部大气相通，内部的压力等于外部大气压，此时冷却水箱排水管中的水在重力作用下流入驱动水箱中与高温蒸汽直接接触换热混合，部分蒸汽降温冷凝，驱动水箱中的压力减小到大气压以下，同时在冷却水箱排水管水流下的过程中，排水管段内的水位球随之下降堵塞排水口，从而控制冷却水量，冷却水箱的补水可以通过杠杆式浮子液位控制装置由供水箱供给；抽水阶段在驱动水箱内部压力小于外部大气压时，下部水源中的水和空气的混合物在压差的作用下通过第五止回阀进入驱动水箱中，空气的进入可以增大驱动水箱内部的压力，随着驱动水箱内部压力的逐渐增大和浮力的作用，冷却水箱进水管段中的水位球逐渐浮上水面，完成一个循环，系统会自动进入下一个阶段，实现水泵的自动运行。The operation of the device is divided into five stages of heating, drainage, steam exhaust, cooling, and water pumping to realize automatic control. In the heating stage, waste heat is used to provide heat for the heating water tank, and the generated water vapor enters the driving water tank through the first check valve. During the process, the pressure inside the driving water tank is greater than the external atmospheric pressure but lower than the drain pressure head, then the water in the cooling water tank and the water source cannot enter the driving water tank under the action of the pressure difference and the check valve, and the water in the driving water tank cannot enter the position. In the higher water storage tank, but because the water inlet of the heating water tank is lower than the drain of the driving water tank, the water in the driving water tank can flow back to the heating water tank to continue heating and evaporating to generate water vapor, which ensures the constant supply of water in the heating water tank , to avoid the hidden dangers caused by the formation of dry steam; in the drainage stage, when the steam entering the driving water tank increases and the pressure in the driving water tank is greater than the drainage pressure, part of the water in the driving water tank is discharged into the water storage tank through the third check valve, and the water from the water source The water is transported from the lower position to the higher water storage tank, and the other part of the water flows into the heating water tank through the second check valve, and continues to be heated by the waste heat source to generate water vapor. During the drainage process, the pressure in the water tank is driven. Larger, the water in the water source and the cooling water tank cannot enter the driving water tank; the exhaust stage is at the end of the drainage process, and when the water level of the driving water tank is lower than the drain connected to the water storage tank, the steam generated by the heating water tank will be discharged to the storage tank through the driving water tank. In the external environment at the entrance of the water tank; during the cooling stage, when the steam is discharged to the external environment, the driving water tank is connected to the external atmosphere, and the internal pressure is equal to the external atmospheric pressure. At this time, the water in the drain pipe of the cooling water tank flows into the driving water tank under the action of gravity The high-temperature steam directly contacts the heat exchange and mixes, and part of the steam cools down and condenses, driving the pressure in the water tank to decrease below the atmospheric pressure. At the same time, during the process of water flowing down the drain pipe of the cooling water tank, the water level ball in the drain pipe section drops accordingly to block the drain outlet, thereby To control the amount of cooling water, the supplementary water of the cooling water tank can be supplied from the water supply tank through the lever type float liquid level control device; in the pumping stage, when the internal pressure of the driving water tank is lower than the external atmospheric pressure, the mixture of water and air in the lower water source passes through under the action of the pressure difference The fifth check valve enters the driving water tank, and the entry of air can increase the pressure inside the driving water tank. With the gradual increase of the internal pressure of the driving water tank and the effect of buoyancy, the water level ball in the water inlet pipe section of the cooling water tank gradually floats to the water surface, completing After one cycle, the system will automatically enter the next stage to realize the automatic operation of the water pump.

(1)该装置利用废热作为热源产生蒸汽，为装置运行提供动力，现有的水泵主要利用电能或燃油，需消耗大量的能源，本发明不消耗电能，从而节约能源，保护环境。(1) The device uses waste heat as a heat source to generate steam to provide power for the operation of the device. The existing water pump mainly uses electric energy or fuel oil, which consumes a large amount of energy. The present invention does not consume electric energy, thereby saving energy and protecting the environment.
(2)该系统中的工质为水，冷却方式为蒸汽与水直接接触，运行过程不会产生有害物质，不会污染水质，不会对环境造成污染。(2) The working medium in the system is water, and the cooling method is direct contact between steam and water. The operation process will not produce harmful substances, pollute the water quality, and will not pollute the environment.
(3)该装置主要包括水箱及阀门，结构简单，无运动部件，便于安装，成本低。而现有水泵主要是机械运动装置，易造成磨损及腐蚀，且成本较高；太阳能水泵造价高且系统部件复杂。(3) The device mainly includes a water tank and a valve, has a simple structure, has no moving parts, is easy to install, and has low cost. However, the existing water pump is mainly a mechanical movement device, which is easy to cause wear and corrosion, and the cost is relatively high; the solar water pump is expensive and has complicated system components.
(4)现有的机械水泵及太阳能水泵输送水温不会变化，保持水源的温度。而该装置所输送的水温较高，可以作为生活热水使用。从加热水箱进入驱动水箱的蒸汽温度高，与冷却水接触后，部分蒸汽冷凝，部分冷却水蒸发，此时驱动水箱中的冷凝水温较高；驱动水箱压力降低进入抽水阶段后，水源中的水与驱动水箱中的水混合后温度高，输送到贮水箱后可以作为生活热水使用。(4) The temperature of the water delivered by the existing mechanical water pump and solar water pump will not change, and the temperature of the water source will be maintained. The temperature of the water delivered by the device is relatively high, so it can be used as domestic hot water. The temperature of the steam entering the driving water tank from the heating water tank is high. After contacting the cooling water, part of the steam condenses and part of the cooling water evaporates. At this time, the temperature of the condensed water in the driving water tank is relatively high; After mixing with the water in the driving water tank, the temperature is high, and it can be used as domestic hot water after being transported to the water storage tank.
(5)太阳能水泵受天气变化影响大，运行不稳定。本发明利用废热作为热源，不受天气因素的制约。系统中运用止回阀、浮球液位控制装置、冷却水量控制装置等可以根据压差自动控制系统运行，完成各过程的自动循环，安全可靠。(5) Solar water pumps are greatly affected by weather changes and run unstable.

所述冷却水箱中设置有杠杆式浮子液位控制装置，由进水阀、杠杆、浮球等零件组成。当水量达到设定水位线时，浮球因浮力上升，驱动进水阀关闭，停止供水；当水量低于设定水位线时，浮球下降，进水阀打开供水，如此循环。The cooling water tank is provided with a lever-type float liquid level control device, which is composed of a water inlet valve, a lever, a float and other parts. When the water volume reaches the set water level, the float rises due to buoyancy, drives the water inlet valve to close, and stops the water supply; when the water volume is lower than the set water level, the float ball falls, and the water inlet valve opens to supply water, and so on.
