Abstract

The invention discloses a column type heat exchanger and an application method and a cleaning and maintaining method thereof and belongs to the field of chemical energy sources. The column type heat exchanger comprises inner straight tubes connected to inner vertical elbows, outer straight tubes and outer tube communicating tubes are connected to form single column type sleeve heat exchangers, adjacent two single column type sleeve heat exchangers are connected through an inner tube connecting tube and an outer tube connecting tube to form a heat exchanger main body, three-way joints of innerand outer rubes are separately connected to the middle parts of the inner and outer connecting tubes for connecting a stop valve, a blowoff pipe and a cleaning tube and the like, ribs are mounted on two sides of each inner straight tube for supporting, and an expansion joint of a corrugated tube is mounted in the middle of each outer straight tube for absorbing thermal expansion of a pipeline. Thecolumn type heat exchanger is reasonable in structural design, and can solve the technical problem that a conventional double-pipe heat exchanger is easy to form scale and block and is not easy to detach, clean and maintain effectively.

Description

technical field [0001] The invention belongs to the field of chemical energy, and relates to a finned heat exchanger, its use method, and its cleaning and maintenance method. Background technique [0002] In energy, chemical, environmental protection and other industries, heat exchangers are one of the important equipment. Many materials in the production process have complex and diverse components. For example, sewage and waste in sewage treatment contain a large amount of organic matter, inorganic salts and solid particles, etc. It is easy to scale on the heated wall of the heat exchanger, thereby blocking the heat exchanger and affecting the efficiency and safety of equipment operation. As the main equipment in the field of chemical industry and environmental protection production, the operating efficiency of the heat exchanger directly affects the operation of the system, and even affects the stability and production efficiency of the system, and the nature of the heat e...
