Description

Technical Field

[0001] The present invention relates to the technical field of air compressor control, and in particular to an air compressor Internet of Things control system and a method thereof. Background Art

[0002] Food processing mainly includes cooking, cooling and packaging. In the food production process, air compressors play an important role, mainly used in the production chain, packaging and cleaning. The working principle of air compressors is mainly to convert mechanical energy into gas pressure energy, and convert the mechanical energy of the prime mover (usually an electric motor) into the energy of compressed air. Air compressors will generate a lot of heat and water vapor during use, but often fail to use this heat reasonably, resulting in energy waste. Therefore, energy-saving methods and measures for air compressors are crucial to reducing energy consumption, reducing operating costs and reducing carbon emissions.

[0003] For example, Chinese patent CN113250933B discloses an air compressor control system based on remote operation and maintenance of the Internet of Things, which is used to solve the problem that when the air compressor is repaired, the existing solution requires professional personnel for maintenance, but in most cases the fault is minor and can be repaired through video remote teaching guidance, but there is a lack of corresponding mechanism, which leads to a longer maintenance cycle. The operation and maintenance module can obtain the air compressors installed in each urban area and the range of the air compressor operation radiation, and obtain the active time of the smart devices within the operation radiation range, and filter the smart devices through the screening module, and select the appropriate smart device to push. When the air compressor sends a fault, the appropriate smart device can be selected to push the fault troubleshooting instructions to shorten the maintenance cycle. If the fault cannot be eliminated, the maintenance personnel will be sent for professional maintenance, because the fault has been eliminated according to the troubleshooting instructions, which reduces the troubleshooting work of the maintenance personnel.

[0004] However, the technology has the following problems: the air compressor will generate a large amount of heat and water vapor during use, which causes a large part of the power of the air compressor to be wasted, resulting in a large waste of energy and making it difficult to achieve the effect of energy saving.

[0024] In order to better achieve the purpose of the present invention, the present invention also provides an air compressor Internet of Things control method, comprising the following steps:

[0025] Step 1: When food is processed in the cooking workshop, a large amount of water vapor is generated. The first solenoid valve is opened, and the first pump body pumps the water vapor into the air compressor, and the air compressor starts to work to pressurize the gas; the air compressor generates heat and water vapor when working, and the second solenoid valve is opened, and the air compressor discharges the water vapor into the gas storage tank for storage;

[0026] Step 2: The heat transfer coil is turned on to discharge the heat generated by the air compressor into the condenser, and then the water supply system introduces water into the evaporator. The fifth solenoid valve is turned on, and the water vapor in the gas storage tank is separated into gas and liquid by the first gas-liquid separator, and then the gas is introduced into the evaporator and the liquid is introduced into the water storage tank.

[0027] Step 3: Add refrigerant into the evaporator again, the refrigerant absorbs heat from the gas in the evaporator, and then evaporates into gas, then the refrigerant enters the second gas-liquid separator through the fourteenth solenoid valve, and then is sucked into the compressor through the fifteenth solenoid valve and compressed into high-temperature and high-pressure gas;

[0028] Step 4: Open the sixteenth solenoid valve, and the heat of the high-temperature and high-pressure gas and the heat generated by the work of the air compressor heat the water together. Following the law of conservation of energy and the second law of thermodynamics, only a small amount of mechanical work is consumed to transfer the heat in the low-temperature environment to the water, drive the compressor, and convert the heat in the compressor from a low-temperature heat source to a high-temperature heat source, so that the water is heated in the condenser, and the tenth solenoid valve is opened to pass a part of the heated water into the packaging workshop to provide hot water for food packaging in the packaging workshop;

[0029] Step 5: For the refrigerant in the condenser, the high-temperature and high-pressure gas will lose heat when entering the condenser, causing the refrigerant to condense into liquid; the refrigerant becomes a low-temperature and low-pressure liquid after being reduced in pressure by the expansion valve and enters the evaporator again to exchange heat with the water source in the evaporator. The refrigerant absorbs heat and evaporates into a gaseous state, realizing water cooling in the evaporator. Then the sixth solenoid valve is opened to pass the cooling water into the cooling workshop to realize cooling of the food processing process;

[0030] Step 6: The seventh solenoid valve is opened to pass the heated water in another part of the condenser into the heat exchanger. The ninth solenoid valve is opened, and the third pump body pumps the high-temperature liquid water generated in the air compressor into the heat exchanger. The eighth solenoid valve is opened to discharge the water in the water storage tank into the heat exchanger. The heat exchanger collects heat from the air compressor, water storage tank, and condenser, and uses the heat for heating the boiler, saving resources and improving the heating efficiency of the boiler. The eleventh solenoid valve is opened to pass the water vapor generated in the boiler into the packaging workshop to moisturize the food.

[0031] Step seven: Finally, open the third solenoid valve, pass the gas in the gas storage tank into the membrane separation device, separate the nitrogen in the membrane separation device, open the exhaust valve, discharge the other gases, then open the thirteenth solenoid valve, the second pump body discharges the nitrogen in the membrane separation device into the gas purification device to purify the gas, then open the twelfth solenoid valve, the second pump body pumps the gas in the first solenoid valve into the packaging workshop to process the food.

[0032] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides the air compressor with the gas required for operation through the cooking workshop, and through the combination of the air compressor and the heat pump system, reasonably utilizes the heat and water vapor generated by the air compressor during operation, and provides cooling water to the cooling workshop, and provides hot water and water vapor required for food moisture retention to the packaging workshop. The present invention also separates and purifies the gas discharged from the air compressor, and transports the purified nitrogen to the packaging workshop, providing the packaging workshop with the nitrogen required for food packaging;

[0033] The present invention reasonably utilizes the heat and water vapor generated when the air compressor is working, avoids energy waste, and reasonably converts the energy to provide the required energy to the cooling workshop and the packaging workshop, effectively improves the work efficiency, and saves the work cost.

[0034] 2. The present invention determines whether the device is in a normal operating state by detecting the air pressure in the air tank by the air pressure detection device and detecting the temperature in the heat exchanger by the temperature detection device. If the air pressure change trend chart or temperature change trend chart generated by the server is different from the air pressure or temperature change under normal circumstances, the server will send an abnormal notification to the maintenance personnel, and the maintenance personnel will come to the site for inspection.

The first solenoid valve (11) is opened, and the first pump body (25) pumps the water vapor into the air compressor (4). The air compressor (4) starts to work to pressurize the gas.
