The utility model makes the high-temperature corrosive gas flow along the axial direction of the flat tube and the same direction as the fins, and the flow channel is straight in the axial direction and parallel to the flow path of the heat exchange medium, thereby enhancing heat transfer and reducing the resistance of the flue gas. Increase cross-sectional flow area, not easy to accumulate dust and scale, and easy to maintain; the use of steel-aluminum composite plate flat tubes not only improves corrosion resistance, but also avoids the use of expensive materials and reduces costs. In a limited temperature area, In the same temperature environment, the heat exchange effect of the longitudinal finned elliptical flat tube heat exchanger is significantly greater than that of the general conventional heat exchanger, and the energy saving effect is significantly improved.
Description
技术领域 technical field
本实用新型属于高温腐蚀性含尘烟气余热回收技术领域，特别是涉及一种烟气余热回收利用的换热装置。The utility model belongs to the technical field of high-temperature corrosive dust-containing flue gas waste heat recovery, in particular to a heat exchange device for flue gas waste heat recovery and utilization.
背景技术 Background technique
新型高效换热器的开发和制造技术一直是能源利用领域研究的热点，它直接关系到化工、电力、石化等行业的能源利用率。新近开发的各种强化技术无非涉及两个方面：管内或管外。管内通常采用改变管壁状况或加入各种插入物的方法，管外则多采用改变折流方式的方法。但他们只能使管内或管外单方面得到强化，工业应用的现状并不理想。The development and manufacturing technology of new high-efficiency heat exchangers has always been a hot spot in the field of energy utilization, which is directly related to the energy utilization rate of chemical, electric power, petrochemical and other industries. The various strengthening techniques that have been developed recently involve nothing more than two aspects: inside or outside the tube. The method of changing the condition of the pipe wall or adding various inserts is usually used inside the pipe, and the method of changing the baffle method is often used outside the pipe. But they can only strengthen the inside or outside of the tube, and the status quo of industrial application is not ideal.
目前针对化工、电力、石化等行业的腐蚀性含尘高温气体的换热器，普遍使用壳管式换热器，其换热管内以水作为传热介质，为强化气侧的传热，通常在换热管管束外面加装翅片，采用错排布置方式，这种烟气换热装置的缺点是气侧阻力较大，很难对含尘气体换热有效，容易积灰堵塞，清灰吹灰也较困难，强烈影响换热效果，并且结构不紧凑，造成设备成本和运行成本都比较高；另外多采用圆形截面管，因受制造工艺条件限制，一般壁厚较大，这样单位换热面积用材较多，设备价格高，同时热阻也较大。At present, shell and tube heat exchangers are generally used for heat exchangers for corrosive dusty high-temperature gases in chemical, electric power, petrochemical and other industries. Water is used as the heat transfer medium in the heat exchange tubes to enhance heat transfer on the gas side. Usually Fins are installed on the outside of the heat exchange tube bundle, and a staggered arrangement is adopted. The disadvantage of this flue gas heat exchange device is that the gas side resistance is relatively large, it is difficult to effectively exchange heat for dusty gas, and it is easy to accumulate dust and block it. The ash is also difficult, which strongly affects the heat transfer effect, and the structure is not compact, resulting in relatively high equipment costs and operating costs; in addition, circular cross-section tubes are often used. Due to the limitation of manufacturing process conditions, the wall thickness is generally large, so the unit exchange rate The thermal area uses more materials, the equipment price is high, and the thermal resistance is also relatively large.
