[0034] As Figure 1 A refrigeration device for flue gas water removal and condensation:

[0035] The mechanical refrigeration device is composed of compressed air purifier, cyclone vortex tube, refrigeration cavity, condensate water discharge device and the like.

[0036] The air source provides compressed air with pressure greater than or equal to 0.4Mpa, which is dehydrated and deoiled by the air purification device, and then enters the cyclone vortex tube through the interface of the vortex generator or the hot air discharge port. The compressed air passes through the vortex generator to generate vortex and separate cold and hot air. The hot air is discharged to the atmosphere through the tail end, and the cold air enters the refrigeration cavity to cool and remove water from the flue gas. The flue gas enters from the lower interface of the refrigeration cavity and is discharged from the upper interface, because the vortex generator generates a large amount of cold air, which causes the temperature in the refrigeration cavity to drop sharply, and the flue gas exchanges heat with the cold air generated by the vortex generator when passing through the refrigeration cavity, and the water in the flue gas is separated out due to the temperature drop. The separated water is collected at the lower part of the refrigeration cavity due to the action of gravity, and a drain port is opened at the lowermost end of the refrigeration cavity and provided with a condensate water discharge device, and the condensate water is discharged to the waste water collector through the discharge device of the drain port for collection;

[0037] Instrument air is dehydrated and deoiled by the compressed air purifying device 1, and the treated compressed air is connected to the interface 2 of the vortex generator 3 or the hot air discharge port 4, enters the vortex generator 3, and separates cold and hot air. The hot air is discharged to the atmosphere through the hot air discharge port 4, and the cold air is discharged to the atmosphere through the cold air discharge port 5 after passing through the condenser body 8.

[0038] The flue gas enters the cold and hot exchanger 10 through the flue gas inlet 6 to exchange cold and heat, and then enters the later stage facility through the flue gas discharge port 7 for flue gas component analysis.

[0039] When the flue gas exchanges cold and heat in the cold and hot exchanger 10, water is separated out due to the drop in temperature, and the water is collected at the lower part of the condenser body 8 due to gravity and is discharged to the waste water collector through the condensate discharge port 9.

[0040] The cold air is continuously separated out by the vortex generator 3 from the purified compressed air, and the cold air continuously exchanges cold and heat with the flue gas through the cold and hot exchanger 10 to reduce the temperature of the flue gas, achieving the purpose of flue gas dehydration.

[0041] As shown in Figure 1 A flue gas dehydration condensing refrigerator, comprising a vortex shunt device, and the cold air output by the vortex shunt device is sent into the cold air cavity of the condenser body 8;

[0042] The condenser body 8 comprises a heat exchange cavity, which is used for sending in flue gas, and the flue gas and the cold air cavity complete heat exchange, so that the flue gas is cooled;

[0043] The heat exchange cavity is provided with a condensate discharge port 9, a flue gas inlet 6, and a flue gas discharge port 7;

[0044] When the application is implemented, the implementation points are as follows:

[0045] The vortex shunt device converts compressed air into cold air, which is sent into the condenser body through the cold air cavity, exchanges heat with the flue gas, reduces the temperature of the flue gas, and promotes the condensation of water vapor into liquid water;

[0046] The key component of the condenser body is the heat exchange cavity, which is used for transferring heat between the flue gas and the cold air, and reducing the temperature of the flue gas to the condensation point through the cooling effect of the cold air, so as to complete water removal;

[0047] The working process of the application is as follows:

[0048] Compressed air generates cold air: the compressed air purifying device sends the air after purification treatment into the vortex shunt device, and the vortex generator generates cold air; the vortex shunt device shunts the compressed air into cold air and sends it into the cold air cavity of the condenser body;

[0049] The cold gas and the flue gas exchange heat: the cold gas enters the heat exchange cavity of the condenser body; at this time, the flue gas enters the heat exchange cavity and exchanges heat with the cold gas; the cold gas lowers the temperature of the flue gas, so that the water vapor in the flue gas reaches the condensation point and forms liquid water;

[0050] Condensed water discharge: during the condensation process, the water in the flue gas is condensed into water droplets, which flow along the drainage groove on the inner wall of the heat exchange cavity; the design of the drainage groove optimizes the flow path of the flue gas and guides the condensed water to the condensed water discharge port; the condensed water is smoothly discharged to the liquid storage pool, avoiding the impact of accumulated water on the performance of the system;

[0051] Flue gas continues to be discharged: after the condensed water is discharged, the flue gas is further processed; through the spiral pipe, the hot air output by the vortex shunt device is sent into the flue gas discharge port to heat the discharged flue gas, so that it forms a hot air flow, further helping the discharge of the flue gas;

[0052] The check valve arranged at the discharge port ensures that the flue gas can only flow in one direction, preventing backflow of the flue gas and ensuring the safety and stability of the system;

[0053] The entire condensation process does not rely on electrical equipment and only uses compressed air as a refrigerant, completing condensation and gas flow through mechanical means; therefore, the equipment is suitable for use in explosion-proof areas and meets the requirements of intrinsic safety, without explosion hazards.

[0054] Specifically, in an embodiment of the present application, the inner wall of the heat exchange cavity is provided with a drainage groove; the drainage groove can adjust the flow direction and speed of the flue gas in the heat exchange cavity, avoiding excessively high or low flow speed of the flue gas. Suitable flow speed helps maximize heat exchange between the cold gas and the flue gas, ensuring that the flue gas is rapidly cooled to the condensation point;

[0055] The design of the drainage groove guides the flue gas to flow along a specific path through the flow guiding effect, avoiding excessively fast or slow flow speed. Through reasonable groove position and angle setting, the flow of the cold gas and the flue gas can be ensured to be more stable and efficient, avoiding condensate accumulation or excessive flow resistance caused by uneven flow;

[0056] The water produced during the condensation process will flow to the condensed water discharge port along the drainage groove; the design of the drainage groove ensures that the condensed water can be quickly discharged, avoiding the formation of water droplets or water accumulation in the heat exchange cavity.

[0057] Specifically, in an embodiment of the present application, the outer surface of the heat exchange cavity is provided with a cooling groove, and a water storage sponge is arranged in the cooling groove for cooling and temperature reduction;

[0058] The cooling groove is arranged on the outer surface of the heat exchange cavity, and the main function of the cooling groove is to further enhance the heat exchange capacity of the heat exchange cavity with the external environment; the cooling groove is filled with a water storage sponge inside, which provides a high-efficiency heat exchange surface through the high specific surface area of the water sponge and the high heat capacity of water.

[0059] The selection of the water storage sponge ensures its strong adsorption capacity for water and high thermal conductivity, which can effectively absorb heat from the outer surface of the heat exchange cavity and conduct it into the cooling water body;

[0060] The water storage sponge can absorb excess heat transferred from the outer surface of the heat exchange cavity, enhance cooling efficiency, reduce heat loss through the device outer surface, and thus improve condensation efficiency; stabilize device temperature: the design of the cooling tank helps to stabilize the temperature inside the condensation system through the heat absorption of the water sponge, avoiding the decrease of condensation effect or overheating of the system due to excessive temperature;

[0061] A liquid storage pool is arranged below the condensate water discharge port 9, and the end of the water storage sponge extends into the liquid storage pool;

[0062] A liquid storage pool is arranged below the condensate water discharge port, and the end of the water storage sponge extends into the liquid storage pool; the design of the liquid storage pool is used to collect condensate water, ensuring that the condensate water can be effectively recovered;

[0063] The end of the water storage sponge extends into the liquid storage pool, which can further guide the flow and accumulate water, avoiding backflow or accumulation of water in the system during the discharge process;

[0064] Improve water recovery efficiency: the end of the water storage sponge extends into the liquid storage pool, which can effectively collect condensate water and maintain the fluidity of water, preventing water from being retained in the system and ensuring that water can be effectively recovered;

[0065] Reduce water accumulation problems: by extending the sponge into the liquid storage pool, condensate water is prevented from stagnating or backflowing during the discharge process, thereby reducing the possibility of water accumulation problems and avoiding blockage or corrosion;

[0066] The vortex flow dividing device is matched with a compressed air purification device 1, which is used to send high-pressure gas to the vortex flow dividing device;

[0067] The compressed air purification device is used to purify the input air, remove impurities, dust and moisture, and then send the purified high-pressure gas to the vortex flow dividing device; the vortex flow dividing device uses these purified high-pressure gases to produce cold air;

[0068] The purification device can use a multi-stage filtration system, including mechanical filtration, activated carbon adsorption or desiccant, etc., to ensure the purity of the air meets the requirements without affecting the analysis of flue gas, avoiding damage to the equipment caused by the gas entering the vortex flow dividing device;

[0069] Improve the quality of cold air production: purified air ensures that the cold air produced by the vortex flow dividing device will not be contaminated, reducing the condensation system failure or efficiency reduction caused by impurities;

[0070] Guarantee the stability of the equipment, reduce the wear and tear of the system caused by gas impurities, and ensure the long-term stability and reliability of the condensing system;

[0071] The hot air output by the vortex flow device passes through the spiral pipe to heat the output flue gas of the flue gas discharge port 7, so that the flue gas of the flue gas discharge port 7 forms a hot gas flow;

[0072] In addition to generating cold air, the vortex flow device also combines with the flue gas system through the generated hot air; the output hot air is guided to the flue gas discharge port through the spiral pipe to heat the flue gas of the discharge port, so that the flue gas can form a stronger hot gas flow;

[0073] The design of the spiral pipe ensures that the hot air is evenly distributed to the flue gas discharge port, forming a more stable hot gas flow;

[0074] Optimize flue gas discharge, by heating the flue gas of the discharge port, the discharge of the flue gas can be accelerated, the residence time of the flue gas in the system is reduced, and the discharge process is optimized;

[0076] A check valve is provided at the flue gas discharge port 7 to allow the flue gas to be discharged unidirectionally to the flue gas discharge port 7;

[0077] A check valve is provided at the flue gas discharge port to ensure that the flue gas can only flow unidirectionally, preventing the flue gas from flowing back into the system during condensation; the check valve can be automatically closed by spring force or gravity to prevent reverse flow of the flue gas;

[0078] Prevent backflow: the check valve ensures that the flue gas is discharged unidirectionally, preventing the condensate from flowing back into the system and causing cross contamination between the condensate and the flue gas, protecting the normal operation of the equipment; avoiding backflow can ensure the stable operation of the entire condensation process and reduce unnecessary maintenance work;

[0079] A check valve is provided at the flue gas inlet 6 to allow the flue gas to be fed unidirectionally into the flue gas inlet 6;

[0080] A check valve is also provided at the flue gas inlet to ensure that the flue gas can only flow unidirectionally into the equipment, preventing the flue gas from the discharge port from flowing back into the system or other gases from mixing into the system, causing contamination or performance loss;

[0081] Ensure the direction of the inlet flow, the check valve ensures that the flue gas always flows in the correct direction, preventing unnecessary air flow disturbance and ensuring the smooth progress of the condensation process;
