Description

Technical Field

[0001] This utility model relates to the field of industrial refrigeration technology, and in particular to a refrigerant drying device. Background Technology

[0002] Many industrial refrigeration equipment are imported, and these devices are expensive. When air gets into the refrigerant in the refrigeration system, it can cause ice blockage, leading to a decrease in the unit's cooling capacity. It can also produce acidic substances that corrode metal materials and reduce the electrical insulation performance of the windings. Furthermore, refrigerant and lubricating oil have different solubilities; if the refrigerant mixes with lubricating oil, it will affect the unit's service life. Currently, most refrigeration equipment uses desiccants to adsorb water, but the effect is unsatisfactory, often leading to internal corrosion, bearing seizure, and high maintenance costs. Therefore, new technical solutions are needed to address these issues. Summary of the Invention

[0003] The purpose of this invention is to manufacture a device for treating moisture in refrigerant, so as to ensure the safe and stable operation of refrigeration equipment and save on equipment maintenance costs.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A refrigerant drying device includes a condenser, an automatic detector, a control unit, a refrigerant pump, a separation chamber, an oil tank, an oil pump, and a heating mechanism. The refrigerant pump is installed on the outlet pipe of the condenser. The refrigerant pump and the separation chamber are connected in series between the outlet pipe and the return pipe of the condenser. The automatic detector is installed on the outlet pipe of the condenser, at the front end of the refrigerant pump. A heat exchange tube and a desiccant are installed in the separation chamber. The heat exchange tube is connected in series with the oil tank to form a loop through two oil pipes. The oil pump is installed on the oil inlet pipe of the heat exchange tube. The control unit is communicatively connected to the automatic detector, the refrigerant pump, and the heating mechanism.

[0006] Furthermore, the heating mechanism includes a heating element installed on the outer wall of the oil tank. The heating element has a built-in heating resistor. The control unit controls the power supply of the heating resistor of the heating element according to the signal collected by the automatic detector and the water vapor content in the outflow pipe, thereby controlling the heating temperature.

[0007] Furthermore, a ball valve is installed on both the outlet pipe and the return pipe of the condenser. The ball valve controls the refrigerant flowing out of and back into the condenser, and also serves to inspect and maintain individual components at the downstream end.

[0008] Furthermore, a filter is installed on the liquid outlet pipe of the condenser, between the ball valve and the refrigeration pump.

[0009] Furthermore, the heat exchange tubes in the separation chamber are arranged in a ring structure. The refrigerant and water in the separation chamber have different boiling points, which realizes the separation of the two substances. The water remains in the separation chamber and is absorbed by the desiccant, while the refrigerant evaporates into a gaseous state and flows into the condenser of the refrigeration device.

[0010] Furthermore, the automatic detector is a humidity sensor that detects the water content in the condenser and the cooler pump, and generates feedback information which is then sent to the control unit.

[0011] Furthermore, the control unit adopts a PLC controller, which has the characteristics of stable operation and strong anti-interference. It controls the heating temperature and the start and stop of the oil pump according to the information fed back by the automatic moisture detector and the program setting conditions based on the information. When the moisture content drops to the set value, the equipment stops running.

[0012] Furthermore, the filter uses porous ceramic material as the filter element, which can prevent the filter material from contaminating the refrigerant.

[0013] In summary, this utility model has the following beneficial effects:

[0014] (1) Based on the different boiling points of refrigerant and water, the refrigerant is allowed to evaporate under heating conditions, and the liquid water is absorbed for water treatment.

[0015] (2) Improve the stability of refrigeration equipment and reduce the operating cost of the equipment;

[0016] (3) Ensure the cleanliness of the refrigerant, increase the service life of the refrigeration system, and be economical and environmentally friendly. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0020] like Figure 1As shown, a refrigerant drying device includes a condenser 1, an automatic detector 3, a control unit, a refrigerant pump 5, a separation chamber 7, an oil tank 9, an oil pump 11, and a heating mechanism. The refrigerant pump 5 is installed on the outlet pipe of the condenser 1. The refrigerant pump 5 and the separation chamber 7 are connected in series between the outlet pipe and the return pipe of the condenser 1. The automatic detector 3 is installed on the outlet pipe of the condenser 1 and at the front end of the refrigerant pump 5. A heat exchange tube and a desiccant 8 are installed in the separation chamber 7. The heat exchange tube is connected in series with the oil tank to form a loop through two oil pipes. The oil pump 11 is installed on the oil inlet pipe of the heat exchange tube. The control unit is communicatively connected to the automatic detector 3, the refrigerant pump 7, and the heating mechanism.

[0021] Furthermore, the heating mechanism includes a heating element 10 installed on the outer wall of the oil tank 9. The heating element 10 has a built-in heating resistor. The control unit controls the power supply of the heating resistor of the heating element 10 according to the signal collected by the automatic detector 3 and the water vapor content in the outflow pipe, thereby controlling the heating temperature.

[0022] Furthermore, a ball valve 2 is installed on both the outflow pipe and the return pipe of the condenser 1. The ball valve 2 controls the refrigerant flowing out of and back into the condenser 1, and also acts on the inspection and maintenance of individual downstream components.

[0023] Furthermore, a filter 6 is installed on the liquid outlet pipe of the condenser 1, between the ball valve 2 and the refrigeration pump 5.

[0024] Furthermore, the heat exchange tube in the separation chamber 7 is arranged in a ring structure. The refrigerant and water in the separation chamber 7 have different boiling points, which realizes the separation of the two substances. The water remains in the separation chamber 7 and is absorbed by the desiccant 8, while the refrigerant evaporates into a gaseous state and flows into the condenser 1 of the refrigeration device.

[0025] Furthermore, the automatic detector 3 is a humidity sensor. The automatic detector detects the water content in the condenser and the cooler pump, and generates feedback information which is then sent to the control unit.

[0026] Furthermore, the control unit adopts a PLC controller 4, which has the characteristics of stable operation and strong anti-interference. It controls the heating temperature and the start and stop of the oil pump according to the information fed back by the automatic moisture detector 3 and the program setting conditions. When the moisture content drops to the set value, the equipment stops running.

[0027] Furthermore, the filter 6 uses porous ceramic material as the filter element, which can prevent the filter material from contaminating the refrigerant.

[0028] Working Principle: The water content is monitored by an automatic detector through the condenser's outlet pipe. The PLC controller analyzes the water content to determine if moisture treatment is necessary. If the water content exceeds the set value, the heating element is activated. Once the set temperature is reached, the refrigerant pump draws in the refrigerant. When the refrigerant temperature reaches approximately 30°C, the liquid refrigerant turns into a gas and returns to the refrigeration unit. The water in the system, having not reached its evaporation temperature, remains liquid and is absorbed by the desiccant. The system cycles until the water content drops to the set level.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
