Description

Proton exchange membrane-based electric pile, hydrogen fuel cell system and rotary drilling rig
Technical Field
The invention relates to a proton exchange membrane-based electric pile, a hydrogen fuel cell system and a rotary drilling rig, and belongs to the field of engineering machinery.
Background
The rotary drilling rig is used as a common engineering machine and is widely applied to the fields of bridge erection, road construction, housing construction and the like. The rotary drilling rigs in the current market mainly comprise a fuel engine power system assembly. However, with the increasing severity of energy crisis and ecological environment problems, the low-carbon, green and sustainable development is gradually becoming the development subject of various fields. The emission requirements in terms of construction machinery are thus increasing. In addition, because of the long-time and high-strength working environment of the engineering machinery, the requirements of operators on the working environment are also continuously improved. Therefore, the rotary drilling rig is urgently required to seek further technical breakthroughs in the aspects of noise reduction, vibration reduction, low carbon emission and the like.
Current attempts on rotary drilling rigs in the direction of energy conservation and emission reduction mainly comprise a range-extending type hybrid rotary drilling rig and a pure electric rotary drilling rig. The former has similar principle with the new energy hybrid electric vehicle which is currently mainstream. Through the mutual cooperation of the lithium battery and the fuel engine, the fuel consumption can be reduced to a certain extent, and the emission is reduced. The rotary drilling rig has relatively limited emission reduction effect and little improvement in noise and vibration of the whole machine operation. Compared with a hybrid range-extending rotary drilling rig, the pure electric rotary drilling rig has the advantages of reducing emission and noise, and can realize zero carbon emission, low noise and low vibration operation. But has the disadvantages of short endurance, long charging time, serious low-temperature energy reduction and the like. Taking a small rotary drilling rig with an average power of 80KW/h as an example. And taking 8 hours as one shift, the total required electric quantity of a single rotary drilling rig is 640KWh. This not only causes the battery module to occupy a large amount of boarding space, but also consumes a large amount of time during the charging process of the battery. In addition, the low-temperature energy reduction problem of the current power battery is common. At-15-20 c the capacity of the battery may even be reduced by more than 30% of the standard capacity. Therefore, the application range of the pure electric rotary drilling rig is relatively narrow. Therefore, a novel rotary drilling rig which can have the advantages of the fuel rotary drilling rig and the pure electric rotary drilling rig at the same time is still needed urgently, low-noise operation and zero-carbon emission in the construction process can be realized, enough endurance can be achieved, and energy reduction is avoided.

The deionization heat sink 102 is disposed above the fuel cell system to ensure that the fuel cell system is always operating at an optimum temperature. The motor pump group 101 is positioned on the same side as the lithium battery module 103 and in front of the latter, and is used for realizing energy conversion and providing hydraulic driving force required by each functional action of the drilling rig. The hydrogen concentration detector 107 is arranged on the periphery of the rotary platform of the rotary drilling rig, is relatively concentrated near the fuel cell system 105 and the hydrogen cylinder 106, monitors the hydrogen concentration at any time, pre-warns the hydrogen leakage in advance, and ensures construction safety.
As shown in fig. 1 and 2, the hydrogen fuel cell system 105 mainly includes a hydrogen jet ejector 201, a humidifier 202, an activated carbon air filter 203, an air compressor 204, a stack 205, and the like.

As shown in fig. 1, the lithium battery module 103 and the hydrogen cylinder 106 are arranged on both sides of the rotary platform 108. The power output process is relatively gentle due to the characteristics of mild reaction conditions and gentle process of oxidation-reduction reaction in the hydrogen fuel cell, so that the power output characteristic of the hydrogen fuel cell system 105 is difficult to meet the working conditions of alternating load of the whole machine, and the output electric energy is required to be stored by the lithium battery module 103 and then output to the motor pump set 101 by the lithium battery module 103.

As shown in fig. 1, a motor pump unit 101 is disposed in front of a lithium battery module 103 to realize energy conversion and provide hydraulic driving force required by the rotary drilling rig when executing each functional action. Because the whole machine of the rotary drilling rig has larger mass, the working condition is mainly large-load and fixed-point construction, and other working processes are the same as the traditional fuel rotary drilling rig except for individual functional actions, and hydraulic driving is adopted. The conversion of the energy form is accomplished by the motor pump unit 101.
As shown in fig. 1, the hydrogen concentration detector 107 is disposed at the periphery of the rotary platform 108 of the rotary drilling rig, and is relatively centralized and near the detachable hydrogen bottle 106 and the fuel cell system 105, so as to monitor the hydrogen concentration, early warn of hydrogen leakage in advance, and ensure construction safety.
Examples
The embodiment provides a rotary drilling rig, which comprises the power system assembly of the rotary drilling rig based on a proton exchange membrane hydrogen fuel cell (PEMFC) system in embodiment 1.
The specific working process is as follows:
after the whole machine of the rotary drilling rig is ignited and started, the lithium battery module 103 with the capacity of 100KWh utilizes the electric energy stored in the lithium battery module to provide the energy required by the whole machine to execute each working action through each electric element. At the same time the hydrogen cylinder 106 begins to supply the hydrogen fuel cell system 105, which begins to start naturally, with a gradual increase in output power from zero to rated power (approximately 600s is required for this process in an environment of-30 c. Approximately 110s is required for forced rapid start). During subsequent operation, the hydrogen fuel cell system 105 always outputs electrical energy at rated power to continuously charge the lithium battery module 103. After the construction is finished, the motor pump set 101 is firstly closed to stop working, the lithium battery module 103 stops discharging outwards, and then the hydrogen gas outlet valve port of the hydrogen cylinder 106 is closed. Since the reaction conditions of the oxidation-reduction reaction in the fuel cell stack 205 are mild and the process is gentle, the unconsumed hydrogen in the internal piping will continue to participate in the reaction after the supply of the gas is stopped. Outputs electric energy and generates heat. Therefore, to protect the fuel cell system 105 and extend the life, the deionizing radiator 102 is required to continue to operate until the internal hydrogen in the pipeline is consumed, and the fuel cell system 105 stops outputting power. In this process, the lithium battery module 103 continuously stores the electric energy externally output from the fuel cell system. Finally, the deionized radiator 102 is closed, the internal reaction of the electric pile 205 is completely stopped, the hydrogen fuel cell system 105 starts to naturally cool, and the whole machine is closed. It is worth noting that, since the complete machine is assembled and the hydrogen is filled, the hydrogen concentration detector 107 at the periphery of the rotary platform 108 should always keep working state, detect time and early warning in advance, and ensure personnel and equipment safety.
The power system assembly of the rotary drilling rig based on the proton exchange membrane hydrogen fuel cell (PEMFC) system can realize long-time operation of the whole rig at rated power, and the detachable hydrogen bottle structure can realize quick energy charging or replacement of a power source, and has short time and high efficiency; carbon emission in the construction process of the rotary drilling rig can be effectively reduced. In the working process, high-pressure hydrogen in the hydrogen bottle and oxygen in the air enter a galvanic pile in the fuel cell system through respective air inlets respectively, only water is generated after the reaction, and zero carbon emission is truly realized; during normal operation, the noise and vibration generated by the operation of the motor pump set and the radiator are very low, and the noise and vibration of other components during the operation process are very low. Compared with a rotary drilling rig of a traditional fuel engine, the rotary drilling rig can greatly reduce vibration and noise of the whole machine operation and greatly improve the working environment of operators; can realize natural starting from zero to rated output power within ten minutes or forced and rapid starting at low temperature within 110 seconds under the working environment of minus 30 ℃. The problem of low-temperature energy reduction is hardly caused, and the application range is wide; the fuel cell system can continuously work at rated power, the power is reduced by 3% within ten thousand hours, and the power is reduced by 27% within thirty thousand hours. Has reliable stability and long service life. Can realize zero carbon emission, quick start at minus 30 ℃, small vibration, low noise, long service life, high stability and extremely high application prospect.
Thus, various embodiments of the present invention have been described in detail. The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present invention, and such modifications and variations should also be regarded as being within the scope of the invention.
