Problems solved by technology

The cleaning of existing heat exchangers is divided into mechanical and chemical methods. These two methods cannot thoroughly clean shell-and-tube heat exchangers, which hinders the use range and efficiency of heat exchangers.
A lot of high-temperature sewage cannot use heat exchangers to recover waste heat due to serious water scaling, resulting in waste of heat sources

Abstract

The invention relates to a housing-and-tube heat exchanging device. The technical scheme is that a plurality of groups of heat exchanging tubes arranged in an inner cavity of a housing; two ends of the heat exchanging tubes are fixed connected through tube plates; a waste water inlet and a softened water outlet are formed in one end of the housing, and a softened water inlet and a waste water outlet are formed in one end of the housing; the softened water outlet, the heat exchanging tubes and the softened water inlet communicate with each other; and the waste water inlet, the inner cavity of the housing and the waste water outlet communicate with each other. The technical problem that it is difficult to completely clean the conventional housing-and-tube heat exchanging devices can be solved; the heat exchanging efficiency of the heat exchanger can be improved; and the service life of the heat exchanger is prolonged.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchange device, in particular to a shell-and-tube heat exchange device. Background technique [0002] Shell and tube heat exchangers are general process equipment for heat exchange operations. Widely used in chemical industry, petroleum, petrochemical, electric power, light industry, metallurgy, atomic energy, shipbuilding, aviation, heating and other industrial sectors. Especially in petroleum refining and chemical processing equipment, it occupies an extremely important position. However, during the use of the heat exchanger, fouling deposits will inevitably appear on the heat transfer surface, and scaling will occur. The thermal resistance of the fouling deposits is high, which greatly reduces the heat transfer rate; The area of ​​the flow channel increases, the flow resistance of the medium increases, and the energy consumption increases. The fouling and clogging of heat exchangers are the most imp...
