Description

Technical Field

[0001] The utility model relates to the technical field of clean utilization of coal, in particular to a purified coal gas cooler. Background Art

[0002] Coal is one of the main energy sources in my country. As people pay more and more attention to environmental protection, the clean use of coal has become a very important process method and social responsibility. Converting coal into coal gas is an extremely important link in the clean use of coal.

[0003] High-temperature coal gas makes it difficult to transport and utilize the coal gas further, and there are certain safety hazards. Therefore, lowering the coal gas temperature is a necessary step in the purification and utilization of coal gas. However, the design structure of the traditional purified coal gas cooler is relatively simple, which makes it inconvenient to efficiently cool the coal gas and to clean the cooling equipment. As a result, there are generally many tiny particles in the furnace gas. These tiny particles are very easy to adhere to the surface of the cooling pipe to form a scaling layer. If the scaling layer is too thick, it will affect the heat exchange of the cooler and reduce the thermal efficiency of the equipment. At the same time, the scouring of the particles can also cause serious wear of the fins. The spacing between the fins is too dense, which can easily cause the medium particles in the equipment to accumulate in the tooth gaps. Long-term accumulation causes the fins to be squeezed and deformed. In addition, the accumulation of medium particles in the tooth gaps greatly reduces the heat exchange efficiency of the equipment, thereby affecting the service life of the equipment.
