Description

Heat exchange tube water leakage detection device

Technical Field

The utility model relates to a detect technical field, in particular to heat exchange tube detection device that leaks.

Background

Under the environment of energy shortage, waste heat recovery, energy conservation and consumption reduction gradually become important means for saving energy. In the field of waste heat recovery, boiler tube heat exchangers are most commonly used. As disclosed in (published) CN212109679U, the patent name of which is a load-adjustable split heat pipe exchanger, in the operation process, due to the influence of vibration of an external system, vibration generated by internal flue gas scouring, vibration generated by large particle falling collision in a flue, stress release at a connecting part and other reasons, the root of a heat exchange pipe in the heat exchange pipe bundle is likely to be broken and leak water, and once a water leakage accident occurs in the heat exchanger, the service life of equipment and the process safety and stability of the flue system are greatly affected.

SUMMERY OF THE UTILITY MODEL

The application is through providing a heat exchange tube detection device that leaks for detect out the heat exchanger tube bank that leaks.

The embodiment of the application provides a water leakage detection device for a heat exchange tube, the method comprises the following steps:

the vibration sounding unit is connected to the heat exchange tube bundle;

the audio receiving unit is arranged at intervals with the vibration generating unit and is used for receiving the sound emitted by the vibration generating unit;

and the audio processing unit is connected with the audio receiving unit and is used for processing the sound received by the audio receiving unit.

On the basis of the above embodiment, the embodiment of the present application may be further modified as follows:

in one embodiment of the present application: the vibration generating unit is a tuning fork. The beneficial effect of this step: the tuning fork has a simple structure, is easy to sound, and can stably transmit the sound.

In one embodiment of the present application: the bottom end of the tuning fork is welded and connected with the heat exchange tube bundle. The beneficial effect of this step: the tuning fork can be stably connected to the heat exchange tube bundle.

In one embodiment of the present application: the audio receiving unit is an explosion-proof recording pen YLY8.8.

In one embodiment of the present application: the audio processing unit is a computer.

One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: through setting up the tuning fork on heat exchanger tube bundle, convert the quivering of heat exchanger tube bundle during operation into sound and send by the tuning fork to transmit this sound to audio processing unit in through audio frequency receiving unit, carry out analysis comparison processing to sound by audio processing unit, thereby the heat exchanger tube bundle of accurate positioning damage, the staff of being convenient for maintains the change fast.
