Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, in particular to a heat exchanger and a ship circulating water gravity heat exchange system. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers some of the heat from a hot fluid to a cold fluid. Heat exchangers play a vital role in chemical, petroleum, power, food, and many other industrial processes. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers, among other applications.

[0003] In the prior art, CN113279835A discloses a plate heat exchanger. The heat exchanger disclosed in this patent can meet the requirements of ship use. The patent also states that high-temperature lubricating oil is introduced into the heat exchanger body from the oil inlet pipe, and the lubricating oil passes through the filter hopper, and the impurities therein remain on the filter screen. Subsequent lubricating oil flushes the filter screen, causing the impurities to flow along the filter screen and be collected near the collection bin. When the ship is impacted by waves and tilts during operation, the first spring is squeezed and contracted by the heat exchanger body under the action of inertia, and the air in the first inner cavity is squeezed by the top of the support leg and flows along the first cavity channel. , the second cavity enters the second inner cavity, the pressure in the second inner cavity increases, the air squeezes the first connecting rod to move to the right, and the first connecting rod rotates along the thread while moving to the right. The first connecting rod drives the cleaning mechanism to move to the right and rotates at the same time, and the brush head rotates in a spiral along the inner wall of the filter. Under the squeezing action of the filter, the brush head and the second connecting rod shrink into the support tube. At the same time, the first connecting rod moves to the right, so that the sealing ring and the second convex ring are separated, and the collection bin opens. When the brush head rotates in a spiral, the mechanical impurities remaining on the inner wall of the filter are swept into the collection bin.

[0004] However, after the impurities flow into the collection bin, it is not easy for the staff to remove the impurities from the collection bin; and when the ship is sailing on a relatively calm sea, the pressure in the inner cavity is not enough to make the cleaning mechanism work, which will affect the cleaning of the filter.
