[0002] The natural gas cooler circulates the natural gas through the internal bent tube bundle for heat exchange and cooling. The cooling effect of normal temperature water on the natural gas is low. During the cooling process, frozen brine can be added to improve the cooling efficiency of the natural gas. However, due to During the heat exchange process of the cooler, the temperature of the frozen brine gradually increases, and the salt in the frozen brine absorbs heat, forming crystals to precipitate, and the gradually increasing crystals are partially adsorbed on the outer surface of the bent tube bundle, forming agglomerated crystal dirt , leading to a decrease in the heat transfer effect inside and outside the bent tube bundle, reducing the cooling efficiency of the natural gas inside the bent tube bundle

Abstract

The invention discloses a natural gas cooler, the structure of which comprises a cooling main engine, a frozen brine inlet pipe, a natural gas inlet pipe, a supporting foot, and a natural gas outlet pipe. , crystals are precipitated, and the crystals are attached to the outer wall of the bent tube bundle. At this time, the outer wall scraping mechanism is driven by the slide bar to move, and the crystal attached to the outer wall of the bent tube bundle is scraped, and the crystal is cleaned by the side baffle. Blocking, the adjustment plate is adjusted by the spring provided between the fixed plate and the adjustment plate. At this time, the shovel plate can better remove the salt crystals on the bottom surface of the inner wall of the body, and the sliding shaft is controlled by the magnetic block set outside the sliding mechanism. Magnetic adsorption, at this time, the ring plate swings outside the bend of the bent tube bundle, and the agglomerated crystal dirt at the bend of the bent tube bundle is better scraped off through the bumps, ensuring normal replacement of the bent tube bundle Heat cooling works.
