Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy, more particularly, it relates to a temperature comprehensive management system and method for gas pressurization process of hydrogen refueling station. BACKGROUND

[0002] The diaphragm type hydrogen compressor is a reciprocating compressor that compresses and transports gas by reciprocating motion of a diaphragm in a diaphragm head. The diaphragm of the compressor is composed of three diaphragm sheets, and the diaphragm is clamped by hydraulic oil and process gas along the periphery to form a diaphragm head. The diaphragm is driven by hydraulic pressure to reciprocate in the diaphragm head, thereby achieving compression and transportation of the gas. The main body of the diaphragm compressor is composed of two systems: a hydraulic oil system and a gas compression system, and the metal diaphragm separates the two systems.

[0003] In the prior art, a cooling device is provided at the gas outlet pipeline of the compressor after gas compression to cool the compressed high-temperature gas, so as to ensure that the temperature of the output gas is close to the ambient temperature. Therefore, refrigeration and heat exchange are required to achieve the purpose of cooling the gas at the outlet of the compressor. The hydraulic oil of the compressor is configured with a heating device to heat the hydraulic oil when the ambient temperature is low to prevent condensation. When the ambient temperature is high, the increase in the temperature of the hydrogen gas at the inlet of the compressor will cause the temperature of the diaphragm head to rise, which not only puts higher requirements on the heat exchange capacity of the outlet of the compressor, but also affects the service life of the sealing material, diaphragm head, etc. of the compressor due to the alternating load of high pressure and high temperature. SUMMARY

[0004] In view of the current situation that the diaphragm head temperature is high and the gas cooling and hydraulic oil heating are not comprehensively managed in the actual application of the compressor, the present application aims to provide a temperature comprehensive management system for gas pressurization process of hydrogen refueling station. Temperature adjusting devices are arranged at the inlet, outlet and hydraulic oil of the compressor to adjust and control the temperature of the gas and hydraulic oil. By collecting the temperature and pressure signals of the gas and hydraulic oil, the three temperature adjusting devices are comprehensively controlled to effectively control the temperature of the compressed gas and hydraulic oil. Based on the above-mentioned temperature comprehensive management system for gas pressurization process of hydrogen refueling station, the present application aims to provide a temperature comprehensive management method for gas pressurization process of hydrogen refueling station.

[0005] The specific scheme is as follows:

[0007] A data acquisition unit comprising a temperature acquisition component and a pressure acquisition component. The temperature acquisition component acquires and outputs the temperature information of the compressor. The pressure acquisition component is arranged in the inlet and outlet pipelines of the compressor to acquire the pressure information of the gas before and after compression.

[0011] By adopting the above technical solution, the heat exchange adjustment assembly can adjust the temperatures of the gas before and after compression respectively. Compared with the existing compressor in which a temperature adjustment device is arranged near the gas outlet pipeline, the gas input into the compressor is pre-cooled, the temperature of the compressed gas is increased during the compression process, and the compressed gas is finally cooled in the output pipeline to output the compressed gas at the accurately controlled reference temperature, thereby prolonging the service life of the compressor.

[0058] The present application will be further described in detail below with reference to the embodiments and figures, but the implementation of the present application is not limited thereto.

[0059] like Figure 1 As shown, a comprehensive temperature management system for the gas pressurization process in a hydrogen refueling station is used to manage the temperature of various components in the compressor, ultimately ensuring that the output compressed gas maintains a constant reference temperature. The comprehensive temperature management system for the gas pressurization process in a hydrogen refueling station includes a data acquisition unit 1 for collecting compressor temperature and gas pressure information, a data storage unit 2 for storing the gas reference temperature and the correlation between gas pressure and temperature, a data processing unit 3 for receiving and processing various gas information, and a heat exchange adjustment component for adjusting the gas temperature before and after compression. The data acquisition unit 1 outputs the collected compressor temperature information and the gas pressure information before and after compression to the data processing unit 3. The data processing unit 3 retrieves the gas pressure-temperature relationship and the output gas reference temperature stored in the data storage unit 2, compares the output gas temperature with the reference temperature, comprehensively determines the heat exchange power of the heat exchange adjustment component in the execution component 4, and outputs an adjustment signal to the execution component 4. The execution component 4 receives and adjusts the gas temperature before and after compression in accordance with the adjustment signal, thereby ensuring that the output compressed gas temperature maintains a constant reference value.

[0060] Detailed, such as Figure 1 As shown, the data acquisition unit 1 includes a temperature acquisition component 11 and a pressure acquisition component 12. The temperature acquisition component 11 is used to acquire compressor temperature information, which specifically includes the internal temperature information of the compressor and the ambient temperature information. The ambient temperature information reflects the initial temperature of the gas entering the compressor intake pipe and can be connected to an external environmental monitoring device to receive the current ambient temperature data output by the external environmental monitoring device. In this embodiment, the ambient temperature information is acquired by direct acquisition. An ambient temperature sensor is set outside the compressor housing to acquire the ambient temperature T in real time. Preferably, the ambient temperature sensor is configured as a non-contact infrared temperature sensor. The direct acquisition of ambient temperature has low hysteresis, does not require other equipment assistance, and has strong adaptability.

[0061] The temperature information inside the compressor includes gas temperature data, and the gas temperature data further includes pre-compression gas temperature data and output gas temperature data. An intake temperature sensor is arranged at one end of an intake pipeline of the compressor close to the compressor, and can measure the temperature t1 of the gas passing through the intake pipeline and about to enter the compressor in real time. An output temperature sensor is arranged at one end of an output pipeline of the compressor far from the compressor, and can measure the temperature t3 of the gas passing through the output pipeline and about to enter the gas storage device in real time. In the embodiments of the present application, the intake temperature sensor and the output temperature sensor are both contact type temperature sensors, such as thermocouples.

[0062] The pressure collection component 12 is arranged inside the compressor. Specifically, an intake pressure sensor is arranged in the intake pipeline of the compressor, and is used to measure the gas pressure data before compression. An output pressure sensor is arranged in the output pipeline of the compressor, and is used to measure the gas pressure data after compression. The data processing unit 3 receives the gas pressure data before and after compression, and calculates the current gas compression ratio. In other embodiments, the data processing unit 3 can also directly obtain the current theoretical gas compression ratio according to the current compression power. However, due to the influence of factors such as temperature environment and service life, there is a certain degree of error between the theoretical gas compression ratio and the actual gas compression ratio. In order to accurately obtain the gas compression ratio and obtain the temperature information, in the embodiments of the present application, the method of calculating the gas compression ratio by measuring the gas pressure before and after compression is adopted.

[0063] During the compression of the gas, the temperature of the gas will rise. The principle is that after the gas is compressed, the distance between the gas molecules will decrease, resulting in an increase in collisions between the molecules, thereby generating heat and causing the temperature of the gas to rise. The data storage unit 2 stores an association relationship between the gas compression ratio and the compressor temperature information, and the association relationship includes a first association relationship between the gas compression ratio and the gas compression temperature change. The temperature rise of the gas after compression according to a certain compression ratio can be calculated from the pressure before and after compression. Since the pre-compression gas temperature t1 can be directly obtained by the intake temperature sensor, the post-compression gas temperature t2 can be obtained.

[0064] The data storage unit 2 is configured as a storage, which can be an internal storage unit of the terminal device, such as a hard disk or a memory of the terminal device, or an external storage device of the terminal device, such as a plug-in hard disk, a smart memory card (SMC), a secure digital card (SD), or a flash card (FC) equipped on the terminal device. In addition, the storage can also be a combination of the internal storage unit and the external storage device of the terminal device. The storage is used to store computer programs and other programs and data required by the terminal device. The storage can also be used to temporarily store data that has been output or will be output. The present application does not limit this.

[0065] AsFigure 3 As shown, the execution assembly 4 includes a heat exchange adjustment assembly for adjusting the temperature of the gas before and after the compressor is compressed and the hydraulic oil, which includes a first heat exchange device for preliminary heat exchange of the air inlet pipeline and a second heat exchange device for preliminary heat exchange of the air outlet pipeline.

[0066] The first heat exchange device includes a first heat exchange pipe arranged outside the air inlet pipeline and a first heat exchange pump for controlling the heat exchange power of the first heat exchange pipe, and the first heat exchange pump receives an adjustment signal to adjust the heat exchange power of the first heat exchange pipe to adjust the temperature of the gas in the air inlet pipeline. The second heat exchange device includes a second heat exchange pipe arranged outside the air outlet pipeline and a second heat exchange pump for controlling the heat exchange power of the second heat exchange pipe, and the second heat exchange pump receives an adjustment signal to adjust the heat exchange power of the second heat exchange pipe to adjust the temperature of the gas in the air outlet pipeline. The first heat exchange pipe and the second heat exchange pipe are connected to an external cooling tower through a cooling circulation pipe, and the heat exchange medium arranged inside is water. By controlling the power of the heat exchange pump to control the circulation rate of the cooling water, the preliminary cooling of the input gas by the first heat exchange device and the secondary cooling of the output gas by the second heat exchange device can be accurately controlled.

[0067] As shown in the figure, Figure 2 The preliminary cooling temperature of the gas through the first heat exchange device decreases from the ambient temperature T to the pre-compression temperature t1 of the input compressor, and increases from the pre-compression temperature t1 to the post-compression temperature t2 during the compression of the gas. After the secondary cooling of the second heat exchange device, the output gas temperature t3 decreases to the set reference temperature t after the accurate adjustment of the two heat exchanges.

[0068] In the hot summer environment, the ambient temperature T is relatively high, and after two targeted temperature adjustments, it also tends to approach the reference temperature t.

[0069] In winter or areas with large diurnal temperature differences, the hydraulic oil system in the compressor will increase in viscosity due to the decrease in temperature, and in cold environments below zero degrees, some components in the hydraulic oil may freeze, causing the hydraulic oil system to malfunction and the compressor to fail to operate normally. In order to timely discover and solve the above problems, a hydraulic oil temperature sensor is arranged on the outer wall of the hydraulic oil cylinder of the hydraulic oil system, and the hydraulic oil temperature sensor is also configured as a thermocouple to collect and output hydraulic oil temperature information.

[0070] In order to regulate the temperature of the hydraulic oil system with low temperature, the heat exchange regulating assembly further comprises a third heat exchange device, the third heat exchange device comprises a third heat exchange pipe arranged around the outside of the hydraulic oil cylinder and a heat exchange three-way valve, the third heat exchange pipe is in communication with the first heat exchange pipe and the second heat exchange pipe, the heat exchange three-way valve is configured as two, including a first three-way valve and a second three-way valve, the first three-way valve is arranged at the connection position of the third heat exchange pipe and the first heat exchange pipe, the second three-way valve is arranged at the connection position of the third heat exchange pipe and the second heat exchange pipe, in detail, the three ports of the first three-way valve are connected with the water outlet end of the first heat exchange pipe, the water inlet end of the third heat exchange pipe and one end of the first cooling circulation pipe away from the cooling tower respectively, the three ports of the second three-way valve are connected with the water outlet end of the second heat exchange pipe, the water inlet end of the third heat exchange pipe and one end of the second cooling circulation pipe away from the cooling tower respectively, and the third heat exchange pipe is in communication with the cooling tower through the third heat exchange pipe.

[0071] The hydraulic oil temperature sensor outputs the collected hydraulic oil temperature information to the data processing unit 3, the data processing unit 3 compares the hydraulic oil temperature in the hydraulic oil temperature information with the normal running temperature of the hydraulic system, and outputs a regulating signal when the hydraulic oil temperature is lower than the normal running temperature. When the heat exchange three-way valve does not receive the regulating signal, the ports of the heat exchange three-way valve connected with the third heat exchange pipe are closed, and the cooling water circulates in the first heat exchange pipe or the second heat exchange pipe. When the three-way valve receives the regulating signal, the port connected with the cooling tower is closed, and the port connected with the third heat exchange pipe is opened, so that the cooling water in the first cooling pipe flows to the third heat exchange pipe to heat the hydraulic oil system, thereby realizing greater energy utilization rate. The heat exchange medium cooled by the hydraulic oil system can also be cooled in a shorter time for the next heat exchange cycle, thereby accelerating the heat exchange cycle speed.

[0076] S4, adjusting an output adjustment signal based on the first correlation relationship, the ambient temperature information, the gas pressure information and the gas temperature information, and adjusting the heat exchange power of the heat exchange adjusting component, so that the compressor outputs the compressed gas with the reference temperature. The output adjustment signal also needs to store a second correlation relationship between the heat exchange power and the temperature change amount.
