U-shaped heating tube, electric heating tube, electric heating tube, liquid electric heating tube

1. Internal dimensions of the tank, length x width x height, and liquid level height.
2. Process temperature, starting temperature, and ending temperature.
3. The process requires a heating or cooling time (h).
Heat exchange (heating, cooling):
Q=V × C × r × β (t2-t1)/T (kcal)
V: Solution volume (liters)
C: Specific heat of solution (kcal/L × ℃)
r: Specific gravity (kg/L)
T1: Initial temperature of the solution
T2: Termination temperature of solution
β: Heat loss coefficient (taken as 1.10-1.30)
If Q is positive, it is the amount of heat required for heating up
If Q is negative, it is the required cooling capacity for cooling
T: Heating or pre cooling time h (hours)
Electric thermal equivalent (electrolytic heat):
Q＝0.864×I×V（Kcal/h）
I: Total current A V: Slot voltage V
Determination of heat exchange area S of heat exchanger:
S＝Q/K×ΔT×t
Q: Heat exchange capacity (kcal)
K: Heat transfer coefficient kcal/m2 × hr × ℃ (refer to heat transfer coefficient table V)
V: Solution volume (liters)
Δ T: Average temperature difference
t: Set heating (cooling) time (h)
Selection:
Determine the heat exchange area of the heat exchanger based on calculations, and determine the number and shape of heat exchanger groups according to the size of the tank (reactor), generally "U", "W", "L",
Coiled tube. When heating, the heat exchanger is placed at the bottom of the container, and the cooling is placed below the liquid level by 100mm, resulting in a "one" shape of the product. Our factory can select models and provide design solutions for users.
