Description

Technical Field

[0001] The present invention relates to the technical field of air compressor waste heat recovery, and in particular to a high-efficiency and energy-saving air compressor waste heat recovery device. Background Art

[0002] In the key processes of dyeing, finishing, and weaving in the textile industry, air compressors serve as core power equipment, and the waste heat generated during their operation accounts for about 70% of the input power. These waste heats are mainly manifested as high-temperature oil and compressed gas. If they are discharged directly, it will not only cause huge energy waste, but also cause the ambient temperature of the workshop to soar, requiring additional air conditioning energy consumption. Currently, textile factories generally use tubular static waste heat recovery devices, such as immersing the exhaust pipe of the air compressor in the dye vat water tank, and indirectly heating the water through serpentine or spiral heat exchange tubes. However, this type of structure has three technical bottlenecks: first, the heat exchange efficiency is low; the cooling water in the fixed heat exchange tube forms a static heat exchanger due to the lack of forced flow. Temperature stratification makes it difficult for the heat of high-temperature oil to be fully transferred to the water. The measured heat recovery rate is less than 40%, and a large amount of waste heat is discharged with the exhaust gas. Secondly, there is secondary loss of heat energy. The compressed air in the textile environment often contains fiber dust. Some equipment uses a pre-dust removal design, and the filtration process causes 10-15% heat loss. Thirdly, textile adaptability is insufficient. The dyeing and finishing process requires a continuous supply of high-temperature hot water at 85-95°C. Static tube heat exchangers are prone to pipe clogging due to scale deposition, and water temperature fluctuations exceed ±5°C, seriously affecting the fixation effect of reactive dyes. More importantly, traditional equipment relies on external pumps to drive the cooling water circulation, and the additional energy consumption offsets some of the recovery benefits.

[0003] For example, the "Air Compressor Waste Heat Recovery Device" disclosed in the Chinese Utility Model Patent (Application Number: CN202322744487.1) states in its specification: Currently, air compressor manufacturers generally do not recover the waste heat generated during the operation of the air compressor. Instead, this waste heat is discharged and wasted, resulting in energy waste. Calculations show that a 120kW air compressor dissipates 302MJ of heat per hour, equivalent to the heat generated by burning 17.7kg of coal or 9.98m3 of natural gas. Therefore, how to recover and utilize this discharged heat energy is a very meaningful task. Most of the existing waste heat recovery devices use a hot air pipe placed in a cold water tank, and use the waste heat of the hot air to heat the water, thereby achieving the purpose of waste heat recovery. Although the traditional hot air pipe adopts a serpentine or spiral shape, the hot air pipe is fixed and the water inside is also stationary, which makes the internal water temperature rise relatively slowly. This will cause the waste heat to be discharged from the pipeline before it is fully exchanged with the water. At the same time, in the prior art, an air compressor waste heat recovery device with application number CN201922039056.9 first performs dust removal on the hot air when recovering and utilizing the waste heat. During the dust removal process, heat will inevitably be lost, resulting in heat waste.

[0004] Therefore, we have made improvements to this and proposed a high-efficiency and energy-saving air compressor waste heat recovery device. Summary of the Invention

[0040] A mounting sleeve 13 is fixedly installed in the middle of the outer side of the heat exchange tube 2, and a transmission shaft 14 extending to both ends is sleeved inside the mounting sleeve 13. Synchronous wheels 17 are fixedly installed at both ends of the transmission shaft 14.

[0041] Working principle: When in use, first connect the waste heat recovery component to the oil outlet pipe of the cooling oil in the inner cavity of the air compressor body 1;

[0042] Oil guide: When in use, the high-temperature oil is transported to the inner cavity of the cooling oil pipe 4 through the connecting pipe 3 and the oil guide ring pipe 12 connected to the other end of the connecting pipe 3, and continuously fills the cooling oil pipe 4 until the oil is transported back to the oil inlet of the inner cavity of the air compressor body 1 through the oil guide ring pipe 12 fixedly installed on the top of the cooling oil pipe 4 and the oil outlet pipe 5 installed on the top;

[0043] Heat conduction cooling: After the oil enters the inner cavity of the cooling oil pipe 4, it contacts the spiral plate 10 through the central shaft 9 installed in the inner cavity of the cooling oil pipe 4. First, the contact area between the oil and the inner cavity of the cooling oil pipe 4 is increased, thereby increasing the heat conduction of the cooling oil pipe 4 to the oil. Secondly, the protrusions 11 evenly distributed on the upper surface of the spiral plate 10 can increase the turbulence of the oil in the inner cavity of the cooling oil pipe 4, thereby ensuring full contact between the oil and the inner cavity of the cooling oil pipe 4, achieving comprehensive heat conduction. After the oil is cooled, it is transported back to the air compressor body 1 through the oil outlet pipe 5.

[0044] High-temperature steam production: After the oil enters the inner cavity of the cooling oil pipe 4, the high temperature of the high-temperature oil is transferred to the outside thereof, and the cooling water filled in the gap between the outer side thereof and the inner wall of the heat exchange tube 2 is heated, and the cooling water is made to generate high-temperature steam. The high-temperature steam rises continuously and is transported to the inside of the steam conduit 23 through the steam guide plate 21 installed on the top of the inner cavity of the heat exchange tube 2. In the initial state, the paraffin bags 24 arranged in the inner cavity of the steam conduit 23 are in a solidified state at a low temperature, and are accumulated on the steam conduit 23 under the action of gravity. The inner cavity of the tube 23 is sealed to a certain extent. However, as high-temperature steam continues to accumulate at the bottom of the paraffin bag 24, the paraffin is continuously melted by the steam and the high temperature is transferred to the silicone rubber sheet 25. The silicone rubber sheet 25 is affected by the high temperature and becomes soft and bends. At this time, the paraffin bag 24 and the silicone rubber sheet 25 will tilt upward under the impact of the steam, thereby opening the steam conduit 23. At this time, the paraffin bag 24 can adapt to the temperature of the oil to achieve the opening and closing degree and speed of the paraffin bag 24.

[0045] Energy conversion: After passing through the steam conduit 23 and entering the inner cavity of the conversion chamber 26, the high-temperature steam will continuously impact the turbine blades 28 sleeved in the inner cavity of the conversion chamber 26, causing the turbine blades 28 to rotate, thereby achieving energy conversion. After the steam has driven the turbine blades 28 to rotate, it will be transported to the inner cavity of the condenser 30 through the air holes 29 and cooled by the downward-sloping condenser 30, causing the high-temperature steam to liquefy and be transported to the interior of the insulation box 37 through the condenser 30 for insulation storage;

[0046] Drive: When the turbine blades 28 rotate under the impetus of high-pressure steam, the connecting shaft 20 installed on the top thereof, the second connecting ring tube 19 fixedly installed on the outside of the connecting shaft 20, and the second synchronous belt 18 cooperate with the synchronous wheels 17 installed at both ends of the transmission shaft 14 to drive the transmission shaft 14 to rotate, thereby driving the first synchronous belt 15 sleeved on the bottom of the transmission shaft 14 to drive the first connecting ring tube 16 and the rotating sleeve 6 to rotate, thereby driving the spiral guide plate 8 to rotate through the rotating sleeve 6 and the right-angle tube 7 installed in the top array, thereby accelerating the flow of cooling water in the inner cavity of the heat exchange tube 2 through the spiral guide plate 8, and continuously transporting the high-temperature cooling water to the inner cavity of the heat exchange tube 2 through the spiral guide plate 8, and transporting the high-temperature cooling water to the inside of the heat exchange tube 2 through the liquid exchange tank 22 opened on the side wall of the heat exchange tube 2, and storing it. At this time, the high-temperature cooling water inside the heat exchange box 37 can be transported to the inside of the dye vat through the outlet pipe 38 connected to the bottom pipe, thereby realizing the waste heat recovery and utilization of the air compressor body 1;

[0047] Transport: When the connecting shaft 20 rotates, it will drive the rotating shaft 31 installed in the top array to rotate, and through the rotating shaft 31 and the semicircular plate 32, it will continuously squeeze the liquid inlet pipe 35, thereby realizing peristaltic transport of the cooling water inside the liquid inlet pipe 35. Since the liquid inlet pipe 35 is connected with the external cooling water, the external cooling water is transported to the inner cavity of the heat exchange tube 2 through the liquid exchange pipe 34, and then cooperate with the driving step to realize reciprocating circulation.
