Description

Shell-and-tube heat exchanger structure easy to clean

Technical Field

The utility model belongs to the technical field of shell-and-tube heat exchangers, and particularly relates to a shell-and-tube heat exchanger structure easy to clean.

Background

Shell-and-tube heat exchangers are also known as shell-and-tube heat exchangers. Is a dividing wall type heat exchanger taking the wall surface of a tube bundle enclosed in a shell as a heat transfer surface. The heat exchanger has the advantages of simple structure, low manufacturing cost, wider flow section and easy scale cleaning; but has low heat transfer coefficient and large occupied area. Can be made of various structural materials (mainly metal materials), can be used at high temperature and high pressure, and is the most widely used type.

The applicant has searched an utility model patent document, namely a cleaning device for a shell-and-tube heat exchanger, which has the authorized publication number of CN213714089U and publication date of 2021-07-16, and the technical field is the same as that of the application, and therefore, the cleaning device can be used as a citation document of the background technology of the application. Through analysis of the technical scheme of the cited document, the following conclusion can be objectively summarized:

although the patent solves the problem that the cleaning device sprays cleaning liquid into the heat exchanger and simultaneously rotates the motor in the device to start working, the rear end plate is driven to rotate together with the heat exchange tube, so that the surface of the heat exchange tube is fully contacted with the cleaning liquid, the cleaning effect is improved, the inside of the heat exchanger can be cleaned without disassembly, and the cleaning device is convenient and quick. However, the device can not clean the formed scale by only rotating the rear end plate and the heat exchange tube together, and the heat exchange tube is easy to break when rotating, so that the ideal effect is not achieved.

Disclosure of Invention

In order to solve the problems in the background technology, the utility model provides a shell-and-tube heat exchanger structure which is easy to clean.

The utility model adopts the following technical scheme: a shell-and-tube heat exchanger structure easy to clean comprises a shell, a motor I, a threaded rod, a sliding rod, a heat exchange tube and a washing mechanism;

the heat exchange tube is arranged between the threaded rod and the sliding rod, the brushing mechanism is in threaded connection with the threaded rod, and the brushing mechanism is in sliding connection with the sliding rod.

Compared with the prior art, the utility model has the beneficial effects that: through threaded rod rotation, make and brush the mechanism and carry out reciprocating motion and wash the heat exchange tube in the casing, protected the heat exchange tube, better washs the heat exchange tube, makes the outer loop drive a plurality of brushes two through slewing mechanism and washs the casing inner wall, better clearance incrustation scale on the inner wall, makes its effect better, has reached ideal effect.
