Description
Technical Field

Background
The tube type heat exchanger and the concentrator are basic heat exchange and evaporation equipment in a plurality of industries such as traditional Chinese medicine, chemical industry, food, biological fermentation, environmental protection and the like, and are especially indispensable heating equipment in concentrating liquid materials.
The traditional shell and tube heat exchanger equipment generally comprises a shell, a tube plate, a shell and tube (heat exchange tube), a seal head and the like, wherein the tube runs through the shell, and heat exchange is carried out through materials of the tube plate and through a medium in the shell. According to the structural characteristics, two materials with different temperatures pass through the heat exchanger and are not contacted with each other, but can exchange heat. The heat exchange capacity and efficiency are determined by the temperature difference between the inside and outside of the tube array, the surface area (heat exchange area) of the tube array and the heat exchange coefficient k.
The flow state of the liquid in the tube array is two, namely laminar flow and turbulent flow. Laminar flow: it is the fluid flow that takes on the lamellar form, the cohesive force dominates, the liquid particles are constrained by viscosity. Turbulence: the fluid flow is in a hybrid shape, inertia force plays a leading role, and the restriction effect of binding force is weakened. The fluid is in laminar flow when flowing at low speed in the tube array, the particles of the fluid move smoothly and linearly along the direction parallel to the tube axis, the flow velocity of the fluid is maximum at the center of the tube array, the flow velocity of the fluid is minimum near the wall of the tube array, and the ratio of the average flow velocity to the maximum flow velocity of the fluid in the tube is equal to 0.5.
For the above reasons, the conventional shell-and-tube heat exchanger only has a good heating effect on the materials close to the tube wall of the shell-and-tube while the heating effect on the materials at the middle point of the shell-and-tube is limited. If the final concentration of the materials to be heated is higher, the viscosity of the materials also becomes higher, the flow rate of the materials at the position close to the tube array wall is low, the materials are excessively heated and evaporated, crystals are easily separated out and then are adhered to the tube wall, a scaling phenomenon occurs, and the situation frequently occurs in evaporation and concentration in the traditional Chinese medicine industry and the salt chemical industry, so that great trouble is caused.
