Method for eliminating vibration of dry quenching heat pipe heat exchanger

Abstract

The invention provides a method for eliminating vibration of a dry quenching heat pipe heat exchanger. The method comprises the following steps: stopping a circulating fan of the heat pipe heat exchanger, starting the circulating fan again after 4.5 to 5.5 minutes and changing the fluctuation direction of gas flow in the heat pipe heat exchanger; gradually reducing dry quenching load, stopping the operation of the circulating fan when the rotating speed of the circulating fan is reduced to the minimal rotating speed, opening a hole in the upper part of the heat pipe heat exchanger, manually cleaning dust and eliminating the internal factors causing the change of the gas flow; welding a reinforcing rib on a cover plate at the top of a box body of the heat pipe heat exchanger to perform reinforcement so as to improve the overall strength of the heat pipe heat exchanger. By the method, vibration of the dry quenching heat pipe heat exchanger can be eliminated and damage to the heat pipe heat exchanger caused by vibration is avoided, so that the service life of the heat pipe heat exchanger is prolonged, consumption cost and maintenance cost of spare parts are reduced, stable operation of the heat pipe heat exchanger is guaranteed, the work rate of equipment is increased and successful conduction of dry quenching production is guaranteed.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a method for eliminating the vibration of a CDQ heat pipe heat exchanger. Background technique [0002] The vibration of the upper part of the CDQ heat pipe heat exchanger is caused by the irregular movement of the airflow in the equipment, that is, the collision of the airflow in the equipment. Long-term vibration will cause damage to the internal pipes of the heat pipe heat exchanger, which will affect the stable operation of the overall working condition of CDQ. [0003] Analysis of the cause of the vibration of the CDQ heat pipe heat exchanger is mainly due to the obstruction of the normal flow direction of the airflow in the flue, and the vibration caused by the collision of the airflow in the heat pipe heat exchanger. The vibration source is the circulating fan, and the vibration is reflected in the heat pipe heat exchanger. Due to the long running time of ...

AI Technical Summary

Problems solved by technology

Due to the long running time of the heat pipe heat exchanger, there is dust in the flue, and the reason for hindering the normal flow of air flow may be the possibility of dust accumulation on the heat pipes in the heat pipe heat exchanger. The dust accumulation may be local, and the local dust accumulation hinders the flow of air flow. The direction of flow causes the airflow to collide with each other in the internal flue of the heat pipe heat exchanger.
