Description

Technical Field

[0001] The utility model relates to the technical field of economizers, in particular to a quick cleaning structure for economizers. Background Art

[0002] Economizer refers to a heat exchanger arranged in the flue at the tail end of the boiler, which uses the waste heat of the exhaust gas to increase the feed water temperature. The economizer heats the boiler feed water into a heating surface of saturated water under the drum pressure. Since it absorbs the heat of the high-temperature flue gas, it reduces the exhaust temperature of the flue gas, saves energy, and improves efficiency, so it is called an economizer. Economizers can be divided into cast iron type and steel tube type according to the materials used; they can be divided into non-boiling type and boiling type according to the degree of water heating. The steel tube economizer is not limited by pressure and can be used as a boiling type. It is generally made of carbon steel pipes with an outer diameter of 32 to 51 mm. Sometimes fins and ribs are added to the outside of the tube to improve the heat transfer effect. The steel tube economizer consists of horizontally arranged parallel elbow pipes (commonly known as serpentine pipes). The function of the economizer is to increase the feed water temperature, reduce the heat loss of flue gas, and improve the thermal efficiency of the boiler. In daily use, the economizer is placed in the flue gas, and a large amount of dust will accumulate on its surface after long-term use, thus affecting its heat exchange efficiency. Therefore, it is necessary to clean the dust on its surface regularly. At present, the cleaning work is basically done manually by the staff, which is not only inefficient but also labor-intensive. Therefore, it is necessary to design a fast cleaning equipment. Utility Model Content
