Description

Shell and tube heat exchanger convenient to it is clean

Technical Field

The utility model relates to a shell and tube heat exchanger especially relates to a shell and tube heat exchanger convenient to it is clean.

Background

The shell and tube heat exchanger is the most widely used heat exchanger in chemical production. The heat exchanger mainly comprises a shell and a core body, wherein the core body is formed by assembling a tube plate, a heat exchange tube and a baffling baffle. When heat exchange is carried out, a fluid enters from the connecting pipe of the end socket, flows in the pipe and flows out from the outlet pipe at the other end of the end socket, which is called a pipe pass; the other fluid enters from a connecting pipe of the shell and flows out from the other connecting pipe on the shell, and the other fluid is called shell side.

The long-term operation of the tubular heat exchanger can cause the equipment to be blocked by water scale, so that the efficiency is reduced, the energy consumption is increased, and the service life is shortened. If scale cannot be removed in a timely manner, there is a risk of equipment maintenance, downtime, or replacement. Traditional cleaning methods is for opening the casing, tears out the core to carry out high pressure water washing to the core, but a lot of problems appear when wasing the heat transfer pipe: for example, the heat exchange tubes are densely arranged, and high-pressure water can only clean the heat exchange tubes positioned on the outer layer but cannot clean the heat exchange tubes positioned on the inner layer, so that deposits such as water scales cannot be thoroughly removed, and the service life of the equipment is shortened.
