Problems solved by technology

However, due to the high viscosity of the fluid medium, its flow resistance in conventional tube or plate heat exchangers is very large, and it is easy to stagnate and scale on the wall surface, which affects the heat transfer effect.
Moreover, uneven heating or cooling due to uneven flow rate, and even scorched deterioration in the dead corner of the flow, lead to blockage and affect product quality

Embodiment Construction

[0010] in figure 1 The high-viscosity material enters the heating section of the spiral-propelled rotating heat pipe (6) through the high-viscosity material inlet pipe (7) to be heated. At the same time, the spiral piece (9) pushes the material in the heat pipe (6) and heater It flows forward in the spiral passage between the jackets (8), and is transferred to the next stage (if necessary) for further heating at the end via a communication union (10). After heating, it flows out through the outlet pipe (11). The heating fluid heats and vaporizes the working fluid in the heat pipe via the sleeve at the bottom of the heat pipe heat exchanger. If it is necessary to cool the high-viscosity heat-sensitive fluid, just place the helical section of the heat pipe below and let the high-viscosity heat-sensitive fluid pass from below.

[0011] figure 2 It shows the cross-sectional structure of the spiral rotating heat pipe heat exchanger. A single helical rotary heat pipe heat exchanger is...

Abstract

The invention is a spiral boosting rotate heat tube exchanger which consists of gravity heat tube, spiral fin, transmission component (such as gear, belt wheel, chain wheel, abrasion wheel), outer sleeve tube and the sealing components. The out driving force is transmitted by the gears to the heat tube spinning the tube. The spiral fins drives the high mucosity liquor flowing outside the heat tube in the spiral channels so to exchange heat with the heat tube. The heat exchanger is able to provide the heated or cooled materials with a uniform temperature field while driving them flowing in the heat exchanger which facilitates the flow condition in the heat exchanger and prevents the jamming and delays the accumulating of the dirt layer. The invention is capable of high mucosity heat sensitive flow heating and cooling techniques.

Description

Technical field [0001] The invention relates to a heat exchanger device, especially a heating and cooling device for high-viscosity heat-sensitive fluids. Background technique [0002] Food, biochemical, pharmaceutical and other industries often encounter heating and cooling problems of high-viscosity heat-sensitive fluids. The heating and cooling process of this type of medium not only requires a constant temperature, but also requires a uniform heating degree. However, due to the high viscosity of the fluid medium, the flow resistance in the conventional tube or plate heat exchanger is very large, which is easy to stagnate and scale on the wall, which affects the heat transfer effect. And because of uneven flow rate, uneven heating or cooling, and even scorching deterioration occurs in dead ends of the flow, leading to clogging and affecting product quality. Therefore, the heat exchanger needs to be injected and cleaned frequently or regularly, and even needs to be disassembled...
