How to clean heat exchanger equipment?

On-line cleaning can be understood as in-situ cleaning or in-situ cleaning, which is defined as: no disassembly of equipment or components, under closed conditions, with a certain temperature and concentration of cleaning fluid on the cleaning device to a strong role, so that the surface of the instrument and equipment cleaning and sterilization methods. The advantage is that the equipment does not need to be shut down and does not affect the normal production and use. The disadvantage is that the cleaning effect is not very good compared to offline cleaning. If the cleaning time is longer, it will affect the stability of the equipment operation.

Causes of Expansion of Spiral Plate Heat Exchanger

After the heater is in place, a level gauge is used to level the heat exchanger, so that each pipe can be connected to the pipeline without any force. After leveling, the inclined shim can be welded firmly with the cheese seat, but not with the flat shim or slide plate below. When more than two overlapping heat exchangers are installed, the upper heat exchanger shall be installed after the lower heat exchanger is located and the anchor bolts are fully fixed.

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.
