Embodiment Construction

[0046] attached Figure 1-8 The drying devices shown are electric-driven modes 1 to 8, and the electric power is provided by an alternator driven by an internal combustion engine or supplied by the grid if conditions permit.

[0047] attached figure 1 The mode 1 using electric drive is shown in the figure, and the specific implementation method is: after the circulating air A is heated in the heat pump condenser 8, it is further heated in the flue gas heat exchanger 6, and enters the fluidized bed drying chamber through the circulating fan 5 3. After the ambient air B is heated in the internal combustion engine cooling water radiator 13, it releases heat in the heat pump evaporator 14, and then is discharged into the atmosphere.

[0048] attached figure 2 The mode 2 using electric drive is shown, and the specific implementation method is: after the circulating air A is heated in the heat pump condenser 8, it is further heated in the flue gas heat exchanger 6, and enters the...

Abstract

The present invention provides an internal combustion engine driven heat pump fluidized-bed drying equipment capable of recovering waste heat, belonging to the field of fluidized-bed drying technology. The heat pump condenser, heat-pump expansion valve, heat-pump evaporator and heat-pump compressor are successively connected and formed into the heat pump system. Said equipment also includes the following components: circulating fan, fluidized-bed drying chamber, cooling fan, dust collector and air pipe, etc.

Description

technical field [0001] The invention belongs to the technical field of fluidized bed drying, and in particular provides an internal combustion engine driven heat pump fluidized bed drying device with waste heat recovery. Background technique [0002] Drying technology is of great significance to the development of the national economy and is widely used in various sectors of industrial and agricultural production. With the advancement of science, technology and economy, new materials and new products are increasing day by day, and a considerable part of them need to be processed by drying process; with the improvement of enterprise group management and product quality requirements, many products or semi-finished products that have been dried naturally in the past , also tends to adopt mechanized drying. [0003] For agriculture, drying is not only a means to ensure long-term storage of grain, but also an important method to improve grain quality. According to the investiga...
