Wherein, 1: fermentor tank; 1-1: stir shaft; 1-2: stirring rake; 2: heat transfer tube; 2-1: water at low temperature inlet; 2-2: high-temperature water outlet; 2-3: dewatering outlet.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 shows the structural representation of the fermentor tank heat-exchanger rig of the utility model embodiment, as shown in the figure, there is shown fermentor tank 1, vertically is arranged on the stir shaft 1-1 at fermentor tank 1 center, and is arranged on the stirring rake 1-2 on the stir shaft 1-1; Some groups of heat exchanging pipe unit have been installed on fermentor tank 1 sidewall, every group of heat exchanging pipe unit comprises the heat transfer tube 2 that vertically spirals and be provided with, the unitary central shaft of heat exchanging pipe is parallel with stir shaft 1-1, heat transfer tube 2 is around the setting of vertically spiraling of the unitary central shaft of heat exchanging pipe, be provided with cooling water inlet 2-1 in the bottom of heat transfer tube 2, its top is provided with high-temperature water outlet 2-2, and heat transfer tube 2 bottoms also are provided with dewatering outlet 2-3.
The unitary number of heat exchanging pipe in fermentor tank 1 can specifically be provided with according to the volume of fermentor tank and the temperature of fermented liquid, and is big when the fermentor tank volume, when heat transfer temperature difference is big, increase the unitary number of heat exchanging pipe in the fermentor tank, otherwise, reduce its number.In order to make heat exchange efficiency reach optimum value, the present embodiment preferably unitary cross section of heat exchanging pipe is set to circle, its radius is set to 300-1500mm, and every group of heat exchanging pipe unit is provided with the heat transfer tube 2 that the 20-300 circle spirals, and the radius of heat transfer tube 2 is set to 10-120mm.
When utilizing above-mentioned improved volution heat-exchanger rig to carry out heat exchange, its specific embodiment is as follows:
During the fermentation, in the time of need lowering the temperature to fermented liquid, the water at low temperature that will be lower than the fermented liquid temperature by extraneous water pump pumps in the heat transfer tube 2 from cooling off water inlet 2-1, water coolant forms stronger turbulent flow from bottom to top in heat transfer tube 2, stronger turbulent flow makes that heat exchange efficiency greatly improves under identical heat interchanging area situation.
