本发明提供一种利用内燃机冷却液能量加热制氢机水罐的装置及方法，具体内容涉及内燃机冷却液循环控制及制氢机加热系统循环水控制。The invention provides a device and method for heating a water tank of a hydrogen generator by using the energy of the coolant of the internal combustion engine, and the specific content relates to the circulation control of the coolant of the internal combustion engine and the control of the circulating water of the heating system of the hydrogen generator.
背景技术 Background technique
向内燃机气缸中通入少量氢气改善传统内燃机的燃烧与排放性能已经被普遍认为是提高内燃机整体经济性及动力性的有效技术手段之一。但目前氢气基础设施建设并不完善，所以掺氢内燃机存在氢气加注困难的问题。近年来，通过车载制氢机随车电解水制氢为氢气的加注及随车储运提供了新的解决途径。但目前所使用的离子交换膜电解水制氢机必须采用去离子水作为电解质。去离子水的冰点为0摄氏度。在寒冷的冬季，环境温度通常会下降到0摄氏度以下。在这样的环境下，制氢机储水罐及离子交换膜中所存留的水极易结冰，从而破坏制氢机的储水及供水装置，并导致离子交换膜的失效。Introducing a small amount of hydrogen into the cylinders of internal combustion engines to improve the combustion and emission performance of traditional internal combustion engines has been generally considered to be one of the effective technical means to improve the overall economy and power of internal combustion engines. However, the current hydrogen infrastructure construction is not perfect, so hydrogen-doped internal combustion engines have the problem of difficult hydrogen filling. In recent years, hydrogen production by on-board electrolysis of water by on-board hydrogen generators has provided a new solution for hydrogen filling and on-board storage and transportation. However, the currently used ion exchange membrane electrolyzed water hydrogen generator must use deionized water as the electrolyte. The freezing point of deionized water is 0 degrees Celsius. In the cold winter, the ambient temperature usually drops below 0 degrees Celsius. In such an environment, the water stored in the water storage tank of the hydrogen generator and the ion exchange membrane is very easy to freeze, which will damage the water storage and water supply device of the hydrogen generator and lead to the failure of the ion exchange membrane.

Since the temperature of the deionized water in the hydrogen generator water tank 14 is greater than 5 degrees Celsius, Thereby the deionized water in the water tank 14 of the hydrogen generator will not freeze.
当制氢机水罐14内去离子水的温度小于等于5摄氏度且大于2摄氏度时，电子控制单元12继续检测水箱进水管温度传感器信号c，当水箱进水管6内冷却液温度大于5摄氏度时，电控单元12通过发出水箱出口电磁阀控制信号a、水箱入口电磁阀控制信号b及放水电磁阀控制信号g，分别关闭水箱出口电磁阀2、水箱入口电磁阀7及放水电磁阀20；同时，电子控制单元12检测加热器温度传感器信号h，为保证制氢机水罐14内的去离子水不会被过度加热影响制氢机17的运行，当加热器温度传感器信号h发来的冷却液温度低于5摄氏度时，电子控制单元通过发出加热器出水管电磁阀控制信号d及加热器进水管电磁阀控制信号e，分别打开加热器出水管电磁阀5、加热器进水管电磁阀9，使热的内燃机冷却液经水箱进水管6、加热器进水管8、加热器进水管电磁阀9进入加热器13，并继续经加热器出水管4、加热器出水管电磁阀5及水箱出水管返回至内燃机，保证内燃机冷却液循环系统的正常运行，并利用冷却液能量为制氢机水罐14内的去离子水加热，且保证为制氢机水罐14内的去离子水不会被过度加热；当加热器温度传感器信号h发来的冷却液温度大于等于5摄氏度时，电子控制单元12判定加热器13充入热冷却液的过程完毕，加热器13内所储存的热的冷却液可以为制氢机水罐14内的去离子水加热并保证制氢机水罐14内的去离子水不结冰，此时，电子控制单元12通过发出水箱出口电磁阀控制信号a及水箱入口电磁阀控制信号b打开水箱出口电磁阀2及水箱入口电磁阀7；同时，电子控制单元12通过发出加热器出水管电磁阀控制信号d、加热器进水管电磁阀控制信号e及放水电磁阀控制信号g分别关闭加热器出水管电磁阀5、加热器进水管电磁阀9及放水电磁阀20，使内燃机冷却液循环系统按原机模式运行。When the temperature of the deionized water in the water tank 14 of the hydrogen generator is less than or equal to 5 degrees Celsius and greater than 2 degrees Celsius, the electronic control unit 12 continues to detect the temperature sensor signal c of the water inlet pipe of the water tank.

After 30 to 120 seconds, the electronic control unit 12 sends out the water discharge solenoid valve control signal g to enable The water discharge solenoid valve 19 is closed again to ensure that the water tank 14 of the hydrogen generator will not be discharged directly after being filled with deionized water again; at the same time, the electronic control unit 12 sends out the control signal a of the solenoid valve at the outlet of the water tank and the control signal of the solenoid valve at the inlet of the water tank b Open the solenoid valve 2 at the outlet of the water tank and the solenoid valve 7 at the inlet of the water tank, and the electronic control unit 12 turns off the heater respectively by sending the control signal d of the solenoid valve of the heater outlet pipe, the control signal e of the solenoid valve of the heater water inlet pipe and the control signal g of the solenoid valve of the water discharge pipe Outlet pipe solenoid valve 5, heater water inlet pipe solenoid valve 9 and water discharge solenoid valve 20, thereby ensuring the normal operation of the internal combustion engine coolant circulation system and the safe operation of the hydrogen production system.
本发明的有益效果是：针对目前所使用的车载制氢机内去离子水在寒冷环境下易结冰的问题，本发明提供一种利用内燃机冷却液能量加热制氢机水罐的装置及方法。通过利用内燃机运行时冷却液循环系统所带走的发动机热量为制氢机水罐内去离子水加热并保温，避免了车载制氢机在寒冷的环境下由于去离子水结冰而导致的损坏。由于本发明所提供的装置并未对内燃机本体的原有结构进行改造，特别是未对水循环系统上的节温器进行改造，只是在需要加热制氢机水罐内去离子水时改变了内燃机冷却液的外循环路径，且改变该循环路径后，热的冷却液进入加热器时仍然可以通过传热与制氢机水罐内的去离子水发生热交换，相当于对内燃机冷却液进行了散热，所以本装置不会对内燃机冷却系统造成损害。由于为去离子水加热所使用的能量来自内燃机冷却液所提供的内燃机多余热能，因此，使用该系统为制氢机水罐内的去离子水加热及保温不会额外消耗内燃机的有效输出功。The beneficial effect of the present invention is: to solve the problem that the deionized water in the currently used vehicle-mounted hydrogen generator is easy to freeze in a cold environment, the present invention provides a device and method for heating the water tank of the hydrogen generator by utilizing the energy of the coolant of the internal combustion engine . By using the engine heat taken away by the coolant circulation system when the internal combustion engine is running, the deionized water in the water tank of the hydrogen generator is heated and kept warm, avoiding the damage caused by the freezing of the deionized water in the hydrogen generator in a cold environment . Since the device provided by the present invention does not modify the original structure of the internal combustion engine body, especially the thermostat on the water circulation system, it only changes the internal combustion engine when it is necessary to heat the deionized water in the water tank of the hydrogen generator. The external circulation path of the coolant, and after changing the circulation path, when the hot coolant enters the heater, it can still exchange heat with the deionized water in the water tank of the hydrogen generator through heat transfer, which is equivalent to the internal combustion engine coolant. Heat dissipation, so the device will not cause damage to the cooling system of the internal combustion engine. Since the energy used for heating the deionized water comes from the excess heat energy of the internal combustion engine provided by the internal combustion engine coolant, the use of this system to heat and keep warm the deionized water in the water tank of the hydrogen generator will not consume additional effective output work of the internal combustion engine.
