Abstract

The invention discloses a descaling and anti-corrosion device, a shell and tube heat exchanger, an air conditioner and a water heater, relates to the technical field of heat exchangers, and solves the technical problem of poor descaling effect caused by the fact that a magnetic field generated by an electronic descaling device in the prior art is not perpendicular to the water flow direction. The descaling and anti-corrosion device comprises a pulsed magnetic field generation assembly, the pulsed magnetic field generation assembly comprises a pulsed magnetic field generation device and a pulsed magnetic field power supply, and the pulsed magnetic field power supply is connected with the pulsed magnetic field generation device and used for enabling the pulsed magnetic field generation device to generate a pulsed magnetic field; and the pulsed magnetic field generation device is mounted in a shell and tube water inlet pipe of the shell and tube heat exchanger and enables the direction of the generated pulsed magnetic field to be orthogonal to the direction of water flow in a shell pass. The descaling and anti-corrosion device not only can reduce the scaling problem, but also can play a role in preventing corrosion.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a scale removal and corrosion prevention device, a shell-and-tube heat exchanger including the scale removal and corrosion prevention device, and an air conditioner and a water heater including the shell-and-tube heat exchanger. Background technique [0002] Shell and tube heat exchangers are widely used in chemical and commercial air conditioners, water heaters and other fields. They are mainly composed of shells, tube sheets, heat transfer tubes, tube boxes, baffles, etc. The required materials can be ordinary carbon Made of steel, copper, stainless steel, etc. When the shell-and-tube heat exchanger is exchanging heat, one kind of fluid enters and flows in the tube from the connecting pipe of the head, and then flows out from the outlet pipe at the other end of the head, which is called the tube side; the other fluid flows from the shell. The connection pipe enters and...
