Anti-blocking condenser

Abstract

The invention relates to the technical field of ship condensers, in particular to an anti-blocking condenser which comprises a heat exchange cavity, the heat exchange cavity is provided with a heat source inlet and a heat source outlet, a heat exchange pipe is arranged in the heat exchange cavity and penetrates through the heat exchange cavity, and an inlet and an outlet are formed in the outer portion of the heat exchange cavity. A heat conduction structure is arranged at the position, close to the heat source inlet, in the heat exchange cavity and penetrates through the heat exchange cavity to extend to the heat exchange pipe inlet. The heat conduction structure is arranged at the heat source inside the condenser, the heat conduction structure conducts steam heat to the heat exchange pipe inlet on the outer side of the heat exchange cavity to heat crushed ice at the heat exchange pipe inlet, the heat of the condenser is fully utilized, crushed ice accumulation is effectively prevented, and the service life of the condenser is prolonged. The defect that cooling water supply is cut off due to the fact that crushed ice blocks an inlet of the heat exchange pipe is overcome, effective deicing is achieved, smooth operation in the heat exchange pipe is further guaranteed, normal work of the condenser in the crushed ice environment is guaranteed, and the practicability of the condenser is improved.

Description

technical field [0001] The invention relates to the technical field of ship condensers, in particular to an anti-blocking condenser. Background technique [0002] During the polar ice-breaking voyage of the ship, the mixture of crushed ice and seawater can easily enter the condenser through the cooling water pipeline. Because the multiple heat exchange tube holes at the tube sheet form a small-pore filter structure, and the tube sheet is thick and thermal resistance is large, The temperature at the tube sheet is low, and the broken ice cannot be melted, resulting in the continuous accumulation of the broken ice at the head tube sheet, resulting in the blockage of the cooling water supply of the heat exchange tube and affecting the normal operation of the condenser; in addition, the heat exchange tube entering the condenser Due to the irregular shape of the internal crushed ice, during the flow of seawater in the heat exchange tube, it may also be stuck in the tube due to the...
