Working principle:
the technical scheme of the exhaust waste heat recovery device is realized as follows: the device is used for tunnel ovens or similar high-power equipment in baked food production workshops, and can continuously run for a whole period of time to continuously generate exhaust waste heat recovery working conditions. The heat exchanger is a combination body comprising a heat exchanger body and a box body, wherein the heat exchanger body is arranged in the box body. The heat exchange body is designed as a wide-channel heat exchange tube bundle and is a special heat exchanger for recovering exhaust heat with fume dirt; because of the wide channel design, oil stains are not easy to gather and block in the heat exchange body to influence heat exchange, so that the heat exchange efficiency of the heat exchange body is slow, and the heat exchange efficiency after being used for one year in a non-greasy dirt cleaning state can be ensured to be more than or equal to 90%. Considering 40-50 mm of the axial distance of the heat exchange tube bundles is based on the premise of ensuring certain heat exchange quantity, and the oil stain can be cleaned conveniently without integrally disassembling the box body; taking the minimum axial distance of the heat exchange tube bundle as an example, the minimum axial distance of the heat exchange tube bundle is 40mm, and the clear distance between the tubes is 25mm; the pipe diameter of the cleaning pipe of the high-temperature high-pressure steam oil stain cleaning device is generally 15-20 mm, and the cleaning pipe can go deep into the pipe to the bottom of the heat exchange body for oil stain cleaning. The heat exchanger end plate and the reinforcing plate are made of steel plates with good heat conductivity, so that waste heat conduction is facilitated. When the exhaust waste heat recovery device works, exhaust air introduced from the outlet of the tunnel oven enters the box body through the air inlet, heat in the exhaust air is transferred to the outer surface of the heat exchange tube bundle in a convection heat exchange mode when passing through the outer surface of the copper tube bundle of the heat exchange body, and the exhaust air subjected to heat exchange is discharged to the atmosphere through the air outlet of the box body, so that the exhaust air temperature in the process is reduced; the heat exchange tube bundle transfers heat from the outer surface to the inner surface of the heat exchange tube bundle in a heat conduction mode; meanwhile, domestic or production water enters the heat exchange tube bundle through the heat exchange body water inlet pipe to perform convection heat exchange with the inner surface of the heat exchange tube bundle, and the water after heat exchange flows out to the domestic or production water reheating system through the water outlet pipe, and the temperature of the water rises in the process. Through the above-mentioned heat exchange process of this device, the heat transfer of air-change water and the heat recovery of airing exhaust are realized.
Through actual measurement, the exhaust waste heat exchange device consisting of the heat exchange body and the box body can realize the heat exchange process that the initial exhaust temperature of a single device in a tunnel oven is in the range of 50-80 ℃, the exhaust air volume is in the range of 11600-7700 m (i.e. the air volume is in the range of 3.1-5.0 m (i.e. the air volume is in the air volume), the temperature rise of the water side from 10 ℃ to 30 ℃ at 20 ℃ and the exhaust air outlet temperature is 30 ℃, and the actual use can be adjusted (for example, the temperature rise of 10 ℃ and 15 ℃ or higher) according to the requirements and the operation conditions; the upper limit of the temperature reached by the water side temperature rise is infinitely close to but does not reach the exhaust inlet temperature (the condition which can occur when the water body on the heated side is circularly heated). The exhaust temperature is basically controlled to be constant with the air outlet temperature of 30 ℃. Based on the factors of the material, the structural mode and the like of the heat exchange body, the measured exhaust temperature of the outlet of the tunnel type oven is usually 50-80 ℃, and the heat transfer coefficient of the utility model is 40-60W/m ≡K; the cross-flow heat exchange mode can select low values in the interval of 40-50W/m ≡K, and the counter-flow heat exchange mode can select high values in the interval of 50-60W/m ≡K. The exhaust air quantity introduced into the waste heat recovery device is not limited to 11600m ≡per hour, but the maximum air quantity is required to run at the air quantity of no more than 30000m ≡per hour, the working pressure of the water side is less than or equal to 0.8MPa, and the resistance of the water side is less than or equal to 1.5mH2O; the air side resistance is less than 150Pa. The device can ensure that the temperature rise of the water side is still above 18 ℃ under the condition of non-cleaning and degreasing after being used under the above conditions. The heat exchange efficiency is ensured to be 90% or more than 90% of the initial state.
The specific heat recovery mode is as follows:
process 1: the exhaust side releases heat. The air exhaust of the tunnel oven enters the box body through the air inlet by the air exhaust pipeline, and then the air exhaust airflow is uniformly distributed to the front end of the heat exchange body by the guide plate, and enters the heat exchange process at the moment. After the exhaust air flow enters the heat exchange body, the exhaust air flow flows through the heat exchange tube bundle in a turbulent flow mode, and heat in the exhaust air flow is transferred to the outer surface of the heat exchange tube bundle in a convection heat exchange mode. And simultaneously, the heat of the outer surface is transferred to the inner surface in the heat exchange tube bundle material in a heat conduction mode under the action of the temperature gradient. In the process that the exhaust air flows from the front end to the rear end of the heat exchange body, heat is continuously transferred to the inner surface of the heat exchange tube bundle in the heat transfer mode, and the temperature of the exhaust air is reduced from the initial 50-80 ℃ to the control temperature of 30 ℃ due to the 'loss' conversion of the heat. Finally, the exhaust air flows out of the heat exchange body and flows out of the box body through the air outlet, so that the air side heat emission process is completed.
Process 2: the water side absorbs heat. The domestic or production water flows into the water separator positioned on the right side of the outer wall of the heat exchange body through the water inlet pipe, and then the water is split into heat exchange tube bundles which are distributed in a serpentine manner at each layer through the water separator to enter the heat exchange process. When the water body flows through the heat exchange tube bundle, heat on the inner surface of the heat exchange tube bundle is transferred to the water body in a convection heat exchange mode. After the temperature of the water body is increased, the water body gathers the water body after the temperature is increased by the heat exchange tube bundle through the water collector positioned at the left side of the outer wall of the heat exchange body, and then flows out to a life or production water system through the water outlet pipe. In the process, the temperature is continuously increased from the initial 10 ℃ to 30 ℃ due to the 'leading-in' conversion of the heat of the water body, and the heat absorption process of the water side is completed.
