技术领域 technical field
本发明涉及余热回收装置，尤其是一种印染行业的自清洁式定型机余热回收器。 The invention relates to a waste heat recovery device, in particular to a waste heat recovery device for a self-cleaning setting machine in the printing and dyeing industry.
背景技术 Background technique
定型机是纺织印染行业中主要耗能设备之一，它是利用热空气对织物进行干燥和整理并使之定型的装置。一般定型机内所需热风温度约为200℃左右，它的废气温度一般在170℃左右，大量余热被排入空气。如果加上燃料燃烧损失以及机体散热损失等，经估算，输入定型机的热量有90%以上由排气散入大气。真正处理织物所消耗的热量只占了输入定型机热量的2.9%。散失的热量不仅浪费能源而且造成环境的污染。一台八节烘箱定型机，如果将定型机的余热回收，可年节煤220吨，直接经济效益12万元以上。目前，全国中等规模印染企业印染定型机约有25000台，如实现改造，可年节煤550万吨，折合年节标煤390万吨。这不仅为社会节约了大量资源，减少了对地球的热污染，而且也将大大提高印染企业的生产效益，降低经营成本；另外，在高温定型作业中会排放含油脂、有机物质及其加热分解或裂解等产生的高温油烟废气。每台定型机一般排放颗粒物150～ 250mg/m3、油烟40 ～ 80mg/m3。所排放的油、烟、尘对人类身体健康和环境具有很大危害，定型机废气排放引起的污染问题也变得越来越尖锐；针对目前定型机高温废气进行余热回收是势在必行的大事。定型机节能的根本途径在于废气的余热回收利用。但是定型机排出的废气温度在200℃以下，是低品质热源，废气中含有油和纤维灰尘，用常规换热器回收热量，有回收效率低、回收设备投资大、回收成本高、换热器被油和纤维灰尘堵住、不容易清洗等缺点，限制了大范围应用。直到热管技术广泛应用后，有了高效的热管换热器，定型机废气余热回收利用得到了发展。但是废气中的油和纤维灰尘，给热管带来不容易清洗的缺点，依然使定型机余热回收器长期稳定的使用受到一定的限制。 The setting machine is one of the main energy-consuming equipment in the textile printing and dyeing industry. It is a device that uses hot air to dry, finish and set the fabric. Generally, the temperature of the hot air required in the setting machine is about 200°C, and the temperature of its exhaust gas is generally about 170°C, and a large amount of waste heat is discharged into the air. If the loss of fuel combustion and heat dissipation of the body are added, it is estimated that more than 90% of the heat input into the setting machine is scattered into the atmosphere by the exhaust. The heat consumed by the actual processing of the fabric only accounts for 2.9% of the heat input to the setting machine. The dissipated heat not only wastes energy but also causes environmental pollution. An eight-section oven setting machine, if the waste heat of the setting machine is recovered, 220 tons of coal can be saved annually, and the direct economic benefit is more than 120,000 yuan. At present, there are about 25,000 printing and dyeing setting machines in medium-scale printing and dyeing enterprises across the country. If the transformation is realized, 5.5 million tons of coal can be saved annually, which is equivalent to 3.9 million tons of standard coal per year. This not only saves a lot of resources for the society, reduces thermal pollution to the earth, but also greatly improves the production efficiency of printing and dyeing enterprises and reduces operating costs; in addition, oil, organic substances and their thermal decomposition will be discharged during high-temperature setting operations. Or high-temperature fume exhaust gas produced by pyrolysis. Each setting machine generally emits 150-250 mg/m 3 of particulate matter and 40-80 mg/m 3 of soot. The oil, smoke, and dust emitted are very harmful to human health and the environment, and the pollution problem caused by the exhaust gas of the setting machine has become more and more acute; it is imperative to recover waste heat from the high-temperature exhaust gas of the current setting machine event. The fundamental way to save energy for the setting machine is to recover and utilize the waste heat of the waste gas. However, the temperature of the exhaust gas discharged from the setting machine is below 200°C, which is a low-quality heat source. The exhaust gas contains oil and fiber dust. Using a conventional heat exchanger to recover heat has low recovery efficiency, large investment in recovery equipment, high recovery cost, and heat exchangers. It is blocked by oil and fiber dust, and it is not easy to clean, which limits its wide range of applications. After the heat pipe technology was widely used, there was a high-efficiency heat pipe heat exchanger, and the recovery and utilization of waste heat from the exhaust gas of the setting machine was developed. However, the oil and fiber dust in the exhaust gas bring the shortcoming that the heat pipe is not easy to clean, which still limits the long-term stable use of the waste heat recovery device of the setting machine.
目前市场上已有一些定型机余热回收器产品，但普遍存在的问题是：设置于定型机余热回收器壳体内的热管不易拆装，清洗困难。这是一个技术难题，由于定型机废气含有大量纤维、油雾，在热交换过程中极易黏附在热管表面，严重影响传热，如不及时清理，便会造成烟气堵塞，使得定型机余热回收器无法正常工作，从而影响余热回收效率。 At present, there are some waste heat recovery products of setting machine on the market, but the common problem is that the heat pipes arranged in the shell of the waste heat recovery device of setting machine are not easy to disassemble and difficult to clean. This is a technical problem. Because the exhaust gas of the setting machine contains a lot of fibers and oil mist, it is easy to adhere to the surface of the heat pipe during the heat exchange process, which seriously affects the heat transfer. If it is not cleaned in time, it will cause the flue gas to block and make the waste heat of the setting machine The recoverer cannot work normally, which affects the efficiency of waste heat recovery.
