Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery equipment, specifically a waste heat recovery and dehydration device for a noodle-making workshop. Background Technology

[0002] Waste heat recovery refers to the recovery and reuse of waste heat generated in industrial processes. Waste heat refers to energy that is not utilized in energy utilization equipment, including waste heat from high-temperature exhaust gases and waste heat from cooling media. The main purpose of waste heat recovery and utilization is to improve energy utilization efficiency, reduce costs, save resources, and reduce environmental pollution. To this end, a waste heat recovery and dehydration device for noodle-making workshops is proposed.

[0003] The existing Chinese utility model patent with publication number CN208757000U discloses a waste heat recovery and dehydration device for exhaust gas, belonging to the technical field of exhaust gas dehydration equipment. This technical solution includes an exhaust gas inlet, a treatment chamber, an S-shaped condenser, and an exhaust gas outlet. The two ends of the treatment chamber are connected to the exhaust gas inlet and outlet, respectively. The bottom of the treatment chamber has a funnel-shaped structure and a drain outlet to facilitate the discharge of water from the treatment chamber. An S-shaped condenser is installed inside the treatment chamber to increase the contact area between the exhaust gas and the condenser. The inlet of the S-shaped condenser passes through one side of the bottom surface of the treatment chamber and connects to a soft water pump, while the outlet passes through the other side of the bottom surface of the treatment chamber and connects to a waste heat boiler. An L-shaped support frame is installed below the exhaust gas outlet inside the treatment chamber. A desiccant is placed on the support frame to further dehydrate the exhaust gas, further reducing its moisture content. This device significantly reduces the moisture content in the exhaust gas, improves exhaust gas utilization efficiency, and achieves effective recovery of waste heat from the exhaust gas.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that the noodle-making workshop generates waste gas during processing. This waste gas contains white plumes and a certain amount of water vapor. Directly discharging the plumes without processing will pollute the air environment, and directly discharging the waste water vapor will also waste water resources. These problems all affect the use of the equipment. Utility Model Content

[0017] 1. This utility model features a processing cylinder installed above the recovery unit, with an air inlet pipe inserted through the right side of the processing cylinder. The air inlet pipe houses the waste heat recovery device inside the processing cylinder, which is equipped with a heat exchanger.

[0027] Please see Figure 1 — Figure 4 In this embodiment, a waste heat recovery and dehydration device for a noodle-making workshop includes a heat recovery unit 1. A waste heat recovery processing mechanism is installed above the heat recovery unit 1. A condensate softening mechanism is connected inside the heat recovery unit 1. The condensate softening mechanism includes an ion exchanger 12 connected inside the heat recovery unit 1. A connecting pipe 14 is connected below the ion exchanger 12. A switch valve 13 is provided in front of the ion exchanger 12. Side doors 11 are provided on both sides of the heat recovery unit 1. A flexible hose 33 passes through the top of the heat recovery unit 1 and connects to the ion exchanger 12. The switch valve 13 is installed in front of the flexible hose 33. The connecting pipe 14 and the drain pipe 4 are interconnected.

[0028] Specifically, an ion exchanger 12 is installed inside the recycler 1. The ion exchanger 12 is connected to the processing cylinder 2 via a hose 33, a water pipe 27, and the processing cylinder 2. After the processing cylinder 2 separates the water vapor in the flue gas, the ion exchanger 12 can remove ions from the water and process and soften the water, making it easier to recycle the water vapor in the flue gas and reduce the waste of water resources.

[0029] The waste heat recovery processing mechanism includes: a processing cylinder 2 installed above the recovery unit 1; an air inlet pipe 21 connected to the upper right side of the processing cylinder 2; an air outlet pipe 22 inserted through the left side of the processing cylinder 2; a valve 23 installed above the air inlet pipe 21; a heater 24 connected below the air outlet pipe 22; a heat exchanger 25 installed inside the processing cylinder 2; and a water pipe 27 connected to the bottom of the processing cylinder 2. A valve 23 is also installed above the air outlet pipe 22; two sets of heat exchangers 25 are provided; and a heat absorption pipe 26 is connected below the heater 24. The heat absorption pipe 26 is interconnected with the air outlet pipe 22 through the heater 24.

[0030] Specifically, an air inlet pipe 21 is inserted through the right side of the processing cylinder 2. The air inlet pipe 21 is a waste heat recovery device. The recovered flue gas device is located inside the processing cylinder 2. A heat exchanger 25 is installed inside the processing cylinder 2. The heat exchanger 25 releases and cools the heat in the flue gas. A large number of tiny water droplets will form in the cooled flue gas. The water droplets are discharged into the recovery unit 1 through the water pipe 27. The excess heat is absorbed and processed by the heater 24, so that the emission temperature of the flue gas is much higher than its saturation temperature. The heated flue gas is in an unsaturated state, achieving the effect of flue gas whitening and processing the flue gas.

[0031] The processing cylinder 2 is externally connected to a connecting device 3. Mounting rings 31 are fixedly installed at both ends of the connecting device 3. An adjusting rod 32 is provided on one side of the connecting device 3, and a flexible hose 33 is provided at the midpoint of the adjusting rod 32. The flexible hose 33 is connected to the lower part of the water pipe 27. The connecting device 3 and the adjusting rod 32 are arranged in a ring-like relationship through the midpoint of the collector 1. The collector 1 is connected to the processing cylinder 2 through the connecting device 3. The mounting rings 31 are fixedly installed on the upper edge of the collector 1, and the side doors 11 are symmetrically arranged through the midpoint of the collector 1. A drain pipe 4 is interconnected on one side of the bottom of the collector 1, and a support rod 5 is fixedly installed below the collector 1.

[0032] Specifically, the collector 1 is connected to the processing cylinder 2 via the connecting device 3, and a flexible hose 33 is connected between the collector 1 and the processing cylinder 2. The flexible hose 33 allows water vapor to circulate, and both the connecting device 3 and the adjusting rod 32 have an adjusting function, which can adjust the distance between the collector 1 and the processing cylinder 2, so that the processing cylinder 2 can discharge water vapor.

[0033] In operation, a processing cylinder 2 is connected to the top of the recovery unit 1. An air inlet pipe 21 is inserted through the right side of the processing cylinder 2. The valve 23 above the air inlet pipe 21 is opened to dissipate external waste heat. Two sets of heat exchangers 25 are installed inside the processing cylinder 2. The heat exchangers 25 release and cool the heat in the flue gas, resulting in the formation of numerous tiny water droplets in the cooled flue gas. These water droplets are discharged into the recovery unit 1 through a water pipe 27. The remaining flue gas then undergoes heat absorption and processing through a heater 24 below the exhaust pipe 22. The flue gas undergoes high-temperature processing, resulting in an unsaturated state and preventing the formation of white smoke upon discharge. This achieves the effect of flue gas dewhitening and environmental protection. Meanwhile, tiny water droplets enter the interior of the recovery unit 1 through the water pipe 27 and hose 33 below the processing cylinder 2. An ion exchanger 12 is connected below the hose 33. The ion exchanger 12 removes ions from the water, softening it. The softened water is then discharged through the drain pipe 4, facilitating the reuse of the condensed water, reducing water waste, and lowering the production cost of the equipment.
