Description

Technical Field

[0001] The present invention relates to the technical field of energy recovery and utilization, and in particular to a heating system for a circulating drum washing machine. Background Art

[0002] As production continues to expand, energy consumption and production costs increase. Currently, the heating part of most circulating barrel equipment uses heating tubes to directly heat the disinfectant. Because the flushing cycle is fast, the water temperature drops quickly, so a high-power heating tube is needed to maintain the temperature. A ten-out model reaches 96 kilowatts, consuming 96 degrees of electricity per hour, and consuming nearly 270,000 degrees of electricity per year, which is a large energy loss. An air compressor is a device that compresses gas into high-pressure gas. Its main purpose is to compress air into high-pressure gas and store it so that it can be released for use when needed. When the air compressor is working, a large amount of heat is generated due to the compressed air. The current heat dissipation method of the screw air compressor is to input the lubricating oil that absorbs the heat of the air compressor and the compressed air carrying the heat into the radiator, and dissipate the heat to the air through air cooling or water cooling. This causes energy waste. Therefore, the present application proposes a circulating barrel washing machine heating system, which transfers the heat generated by the air compressor to the circulating barrel washing machine to heat the medicine solution, recycles the energy, and at the same time reduces the energy consumption of the heating tube and reduces energy loss.

[0003] The present invention is intended to provide a heating system for a circulating drum washing machine to solve the problems raised in the above background technology.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A circulating drum washing machine heating system includes an air compressor body, a heat exchange mechanism, a circulating pump and a disinfectant tank. The air compressor body is connected to a high-temperature lubricating oil outlet pipe and a high-temperature compressed air outlet pipe. The heat exchange mechanism is used for heat exchange. The high-temperature lubricating oil outlet pipe and the high-temperature compressed air outlet pipe are connected to the heat exchange mechanism. The heat exchange mechanism is connected to a water inlet pipe and a water outlet pipe. The disinfectant tank is connected to a heat exchange pipe. The water inlet pipe and the heat exchange pipe are detachably connected. The water outlet pipe is connected to the circulating pump. The circulating pump is connected to a hot water pipe, and the hot water pipe is connected to the heat exchange pipe.

[0006] Preferably, the heat exchange mechanism includes a heat exchange box, which is provided with two groups. The heat exchange box is connected to a heat exchange inner circulation frame, and the heat exchange box is connected to an outer closed frame. The heat exchange inner circulation frame is located on the inner side of the outer closed frame. The heat exchange inner circulation frame is made of heat-conducting material. The two groups of outer closed frames are commonly connected to a connecting pipe. The high-temperature lubricating oil outlet pipe and the high-temperature compressed air outlet pipe are respectively connected to the two groups of the heat exchange inner circulation frames. The two groups of the heat exchange inner circulation frames are respectively connected to an exhaust pipe and an oil outlet pipe.

[0010] Preferably, the water inlet pipe, hot water pipe and heat exchange pipe are connected with flanges respectively, and the water inlet pipe, hot water pipe and heat exchange pipe are detachably connected by flanges and bolts.

[0011] Compared with the existing technology, this technical solution has the following beneficial effects:

[0012] (1) This technical solution adopts a circulation system, which directly leads the high-temperature lubricating oil output by the air compressor body into the heat exchange mechanism, and outputs water into the heat exchange mechanism through a circulation pump, converting the heat of the high-temperature lubricating oil into heating water. The water in the pipeline is continuously circulated by the circulation pump, so that the water is continuously heated and the temperature is continuously increased. The circulation pipeline is connected to the heat exchange pipe in the disinfection solution tank, and the hot water flows into the heat exchange pipe, and then the heat is transferred to the solution, so that the solution heats up quickly, and the heat used by the air compressor is recycled and reused. At the same time, the energy used by the heating pipe to heat the solution is reduced, and the energy utilization efficiency is optimized.

[0013] (2) In this technical solution, the heat exchange tube is arranged in a spiral shape, which increases the contact area between the heat exchange tube and the disinfectant solution, and at the same time increases the flow time of hot water in the disinfectant solution tank, increases the heat exchange time, and thus improves the heating effect of the disinfectant solution; the water flow path is controlled by setting the heat exchange inner circulation frame and the outer closed frame, so that the water can fully cover the heat exchange inner circulation frame, increase the contact area between water and high-heat compressed air or high-heat lubricating oil, and improve the heat recovery efficiency; at the same time, the heat exchange inner circulation frame and the outer closed frame are distributed in an S shape, which increases the heat exchange time between water and high-heat compressed air or high-heat lubricating oil, further improves the heat exchange recovery efficiency, and further improves the energy recovery rate.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0019] like Figures 1 to 3 The shown circulating drum washing machine heating system includes an air compressor body 1, a heat exchange mechanism, a circulating pump 3 and a disinfectant tank 4. The air compressor body 1 is connected to a high-temperature lubricating oil outlet pipe 6 and a high-temperature compressed air outlet pipe 5. The heat exchange mechanism is used for heat exchange. The high-temperature lubricating oil outlet pipe 6 and the high-temperature compressed air outlet pipe 5 are connected to the heat exchange mechanism. The heat exchange mechanism is connected to a water inlet pipe 7 and a water outlet pipe 8. The disinfectant tank 4 is connected to a heat exchange pipe 10. The heat exchange pipe 10 is made of a heat-conducting material and is spirally arranged. The water inlet pipe 7 is detachably connected to the heat exchange pipe 10. The water outlet pipe 8 is connected to the circulating pump 3. The circulating pump 3 is connected to a hot water pipe 9. The hot water pipe 9 is detachably connected to the heat exchange pipe 10. The heat exchange mechanism includes a heat exchange tank 2. The heat exchange box 2 is provided with two groups, and the two groups of heat exchange boxes 2 are connected. The inside of the heat exchange box 2 is connected to a heat exchange inner circulation frame 12, and the heat exchange box 2 is connected to an outer closed frame 13. The heat exchange inner circulation frame 12 is made of a heat conductive material, and the outer closed frame 13 is made of a heat insulating material. The heat exchange inner circulation frame 12 is located inside the outer closed frame 13, and a flow channel is formed between the inner wall of the outer closed frame 13 and the outer wall of the heat exchange inner circulation frame 12. The flow channel is used for water flow. The two groups of outer closed frames 13 are commonly connected to a connecting pipe 11, and a high-temperature lubricating oil outlet pipe 6 and a high-temperature compressed air outlet pipe 5 are respectively connected to the heat exchange inner circulation frames 12 in the lower heat exchange box 2 and the upper heat exchange box 2. The two groups of heat exchange inner circulation frames 12 are respectively connected to an exhaust pipe 14 and an oil outlet pipe, as shown in FIG. Figure 2 As shown, the heat exchange inner circulation frame 12 connected to the high-temperature compressed air outlet pipe 5 is connected to the exhaust pipe 14, the heat exchange inner circulation frame 12 connected to the high-temperature lubricating oil outlet pipe 6 is connected to the oil outlet pipe, the water inlet pipe 7 and the water outlet pipe 8 are respectively connected to two groups of external closed pipes; the heat exchange inner circulation frame 12 and the external closed frame 13 are arranged in an S shape; the water inlet pipe 7, the hot water pipe 9 and the heat exchange pipe 10 are respectively connected to the flange 16, and the water inlet pipe 7, the hot water pipe 9 and the heat exchange pipe 10 are detachably connected by the flange 16 and bolts.

[0020] The air compressor body 1 processes the lubricating oil and air together. After passing through the oil-gas separator inside the air compressor body 1, the high-temperature compressed air and the high-temperature lubricating oil flow out of the air compressor body 1 respectively. The high-temperature compressed air flows along the high-temperature compressed air outlet pipe 5, and then flows into the heat exchange inner circulation frame 12 of the upper heat exchange box 2, and flows along the heat exchange inner circulation frame 12; the high-temperature lubricating oil flows along the high-temperature lubricating oil outlet pipe 6, and then flows into the heat exchange inner circulation frame 12 in the lower heat exchange box 2. The water outlet pipe 8, the water inlet pipe 7, the hot water pipe 9 and the heat exchange pipe 10 form a circulating water circuit. The circulating water circuit is filled with hot water for exchange. The hot water for exchange is treated in a low-temperature state in the water inlet pipe 7. Under the action of the circulating pump 3, the low-temperature hot water for exchange is input into the outer closed frame 13 in the upper heat exchange box 2 along the water inlet pipe 7, and the hot water for exchange flows along the outer closed frame 13. When the hot water flows along the outer closed frame 13, it is completely connected with the high-temperature compressed air flowing in the heat exchange inner circulation frame 12 The heat exchange is completed, so that the temperature of the low-temperature hot water increases and the temperature of the high-temperature compressed air decreases. The compressed air that has completed cooling is output along the exhaust pipe 14 for storage or input into the product for use. The hot water after absorbing heat flows out from the connecting pipe 11 and enters the outer closed frame 13 in the lower heat exchange box 2 along the connecting pipe 11, and then continues to exchange heat with the high-temperature lubricating oil flowing along the heat exchange inner circulation frame 12 in the lower heat exchange frame, so that the hot water continues to absorb heat. The cooled lubricating oil continues to flow into the air compressor body 1 along the oil outlet pipe for continued use. The heated hot water flows out along the water outlet pipe 8, flows into the hot water pipe 9 under the action of the circulating pump 3, and then flows into the heat exchange pipe 10. The hot water exchanges heat with the disinfectant in the heat pipe, so that the temperature of the disinfectant water increases and the temperature of the hot water decreases again. The hot water after the temperature is reduced flows into the water inlet pipe 7 and circulates along the above process again to complete the continuous heating of the disinfectant.
