Embodiment Construction
[0026] In order to understand the above-mentioned purpose, features and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0027] It should be noted that, in this article, "first" and "second" are only used to distinguish different components, and cannot be used as a limitation of the components themselves.
[0028] see figure 1 , a heat recovery device for recovering the heat in the waste gas containing pollutants. Those skilled in the art can understand that the waste gas should contain heat that can be recovered, such as high-temperature organic waste gas. Specifically, the heat recovery device includes particle feeding device, a first cross-flow moving granular bed 10, a seco...

The invention discloses a heat recovery device which is used for recovering heat in waste with pollutants. The heat recovery device comprises a particle throwing device, a first cross-flow type movable particle bed, a second cross-flow type movable particle bed, a circulating channel, and a reverse-flow type particle movable bed on the circulating channel. The particle throwing device, the first cross-flow type movable particle bed and the second cross-flow type movable particle bed are sequentially connected. The circulating channel is communicated with the second cross-flow type movable particle bed and the particle throwing device. The particle throwing device is used for throwing heat storage particles to the first cross-flow type movable particle bed. The reverse-flow type particle movable bed is used for clearing heat storage particles. Heat storage particles sequentially pass through the first cross-flow type movable particle bed, the second cross-flow type movable particle bed and the reverse-flow type particle movable bed and return to the particle throwing device. According to the technical scheme, heat transfer is achieved through the heat storage particles; the first cross-flow type movable particle bed recovers heat, captures pollutants and is then automatically cleaned so that heat recovery and pollutant removal can be continuously conducted.
Description
technical field [0001] The invention relates to the field of energy saving and emission reduction, and more specifically relates to a heat recovery device, especially a device for recovering heat from waste gas containing pollutants. Background technique [0002] Industrial waste gas is very common in industrial production. Many industrial waste gases have a high temperature, and direct discharge is likely to cause environmental pollution and waste energy. However, the waste heat of waste gas has certain utilization value. Therefore, heat recovery for waste gas has received greater attention in production. , but because the air contains certain pollutants, when the traditional heat exchanger is used to recover the heat in the exhaust gas, the heat exchanger is easily blocked by the pollutants, which affects the life of the heat exchanger and causes the cost of heat recovery from the exhaust gas to be high No less, even more harm than good. [0003] For example, the producti...
