Do you know what are the characteristics of spiral plate heat exchanger?

The spiral plate heat exchanger has good heat transfer efficiency, because by observing the appearance of the spiral plate heat exchanger, we will find that there are some spiral channels with curved shapes and some fixed distance columns in the structure of the spiral plate heat exchanger. In this way, when the spiral plate heat exchanger works, it can effectively enhance the fluid resistance when passing through some channels in a very turbulent state, in this way, the designed flow rate can be effectively improved and the whole heat transfer coefficient can be effectively improved to ensure good heat transfer efficiency. Generally speaking, when a spiral plate heat exchanger is used for heat exchange between water and water, the heat transfer coefficient of the spiral plate heat exchanger can reach 3.5 kW per degree Celsius per square meter.

Structure of storage tank

Tank bottom: the tank bottom is assembled by steel plates, the steel plate in the middle of the tank bottom is the middle plate, and the surrounding steel plate is the edge plate. The edge plate may be a strip plate or an arcuate plate. In general, when the inner diameter of the storage tank is less than 16.5m, the strip edge plate should be adopted, and when the inner diameter of the storage tank is ≥ 16.5m, the arcuate edge plate should be adopted.

What are the characteristics of the storage tank?

According to the material of the storage tank: the materials required for the storage tank project are divided into tank materials and ancillary facilities materials. Tank materials can be divided into low-strength steel and high-strength steel according to tensile yield strength or tensile standard strength. High-strength steel is mostly used for storage tanks above 5000m3. Auxiliary facilities (including wind-resistant ring beams, locks, spiral ladders, guardrails, etc.) are all made of ordinary carbon structural steel with low strength, while other accessories and accessories are made of other materials according to different uses. Domestic steels commonly used for tank manufacturing are 20, 20R, 20R, 16Mn, 16MnR, 16MnR and Q235 series.

Precautions for the use of storage tanks

The operation of this equipment must be strictly and systematically trained. Operators who have passed the examination (written and actual operation) and obtained the equipment operation certificate shall operate the equipment. Any personnel without training shall not operate the equipment.

What is a tower?

The tower is a process equipment with a cylindrical welded structure, consisting of a cylinder, a head (or head) and a support. It is a non-standard equipment designed and manufactured specifically for certain production process requirements. Tower is used for distillation, purification, absorption, distillation and other chemical unit operation of vertical equipment, widely used in gas-liquid and liquid-liquid phase between the mass transfer, heat transfer. According to the classification of tower internals structure, the tower can be divided into plate tower and packed tower. If the container only contains materials and does not carry out chemical reactions and other physical and chemical processes, there are no facilities or only simple auxiliary structures, also known as tanks. Vessels are divided into vertical type (vertical axis) and horizontal type (horizontal axis). Most of the tower belongs to the pressure vessel.
