Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a detachable chimney structure and a ship. Background Art

[0002] Chimneys are an indispensable and important structure in ships. They are usually square or circular structures and are located in the middle of the ship or on the decks on the left and right sides. Especially for special transport ships, the engine room is usually located in the rear of the ship. The chimney is connected to the engine room and is located on the deck above the engine room. The size of the chimney is closely related to the power of the main engine of the ship. Generally, ships with stronger carrying capacity require more powerful and more main engines, which leads to an increase in the ventilation area required, and the volume of the chimney also increases accordingly.

[0003] Chimneys are usually on the same deck as cranes and other equipment. The location of the chimney is limited by the engine room and cannot be placed arbitrarily. In order to avoid collisions between chimneys and equipment such as cranes and other equipment that require a large operating space, the equipment needs to be placed away from the chimney. When the deck space of a ship is relatively small, smaller equipment has to be selected due to the limitation of the operating space. At the same time, some ships require operating vehicles to drive onto the deck for operations. The presence of chimneys on the deck will limit the width of the operating vehicles on the deck, and also affect the operating efficiency of the vehicles on the deck.

[0004] Therefore, a detachable chimney structure and a ship are needed to solve the above problems. Utility Model Content
