A kind of solid of membrane type multi-layer vibration conveying and fluid heat exchanger
Technical field
The present invention relates to the wall-type heat exchange technical field of solid material and fluid, be specially solid and the fluid heat exchanger of the conveying of a kind of membrane type multi-layer vibration.
Background technology
Along with the fast development of modern industrial technology, what require solid material and fluid heat exchanger has larger exert oneself (conveying capacity and exchange capability of heat).The requirement single device of some chemical system is exerted oneself and is reached 50 ~ 100t/h, and also reaches 30t/h for the separate unit quantity of slag of the CFB boiler slag-cooling device of 300MW.
When using as material cooler, in order to obtain higher system effectiveness, needing to obtain higher heat carrier energy grade, namely making fluid reach higher outlet temperature and pressure.When using as heating material or drier, higher fluid side temperature, pressure ability to bear obviously also provides the wider scope of application.
