How Coolers Can Be Designed To Improve Efficiency
Due to the spiral shape of the cooler, the version with less resistance should be selected when selecting the version, and the plate type or corrugated type should be determined according to the actual needs of the heat exchange site. For environments with large flow rates and small allowable pressure drop. On the contrary, choose the plate type with high resistance.
According to the environment of fluid pressure and temperature, it is determined to choose the detachable type, or the brazing type. When determining the plate type, it is not suitable to choose a plate with a small veneer area, so as to avoid too many plates, a small flow rate between the plates, and a low heat transfer coefficient. This problem should be considered more carefully for larger coolers.
In order to improve the pressure bearing capacity of the spiral plate, a spacer column is used between the plates to support. There are two types of fluid intake and outlet openings on the cylinder body: normal receiving and tangential receiving. China widely uses tangential acceptance, its fluid resistance is small, and impurities are easily washed out by the stainless steel reaction pot. It is more convenient to use the reversing spreader support, which can make the cooler stand or lie down.
The heat-exchanging fluids A and B flow through the two sides of the spiral plate respectively, and one of the fluids flows from the outside to the inside along the spiral channel and flows out to the central outlet. The working temperature of the cooler is determined by the selected materials, most of which are carbon steel, stainless steel, aluminum, copper and titanium.
The so-called heat transfer enhancement or heat transfer enhancement of the cooler means that through the analysis and calculation of various factors affecting the heat transfer, some technical measures are taken to improve the heat transfer of the heat exchange equipment or to make the heat transfer under the condition of satisfying the original heat transfer. It shrinks in size.
As a device that realizes heat transfer between two materials in industrial production, coolers have been widely used in the chemical industry. As a type of coolers, coolers are also used in all aspects of the chemical industry. auxiliary production equipment.
Fouling problems with coolers are the most common form of failure. The best way to solve the fouling of the cooler is to strictly operate the process regulations, maintain good daily maintenance, and carry out regular cleaning.
