Problems solved by technology

[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 cooler structurally comprises a cooling main machine, a frozen saline water inlet pipe, a natural gas inlet pipe, supporting legs and a natural gas outlet pipe, wherein the frozen saline water inlet pipe is fixedly arranged at the upper end of the cooling main machine and communicates with the cooling main machine. According to the cooler, frozen saline water absorbs heat to form crystals to be separated out, and the crystals are attached to the outer wall of a bent pipe bundle; at the moment, an outer wall scraping mechanism is driven to movethrough a sliding rod, the crystals attached to the outer wall of the bent pipe bundle are scraped, the crystals are blocked through side baffles, and an adjusting plate is adjusted through a spring arranged between a fixing plate and the adjusting plate; at the moment, the salt crystals on the bottom face of the inner wall of a machine body are well shoveled away through a shoveling plate, and asliding shaft is magnetically attracted through magnetic blocks arranged outside a sliding mechanism; and at the moment, an annular plate swings outside the bent position of the bent pipe bundle, andthe caked crystal dirt at the bent position of the bent pipe bundle is well scraped off through protruding blocks, so that the normal heat exchange cooling work of the bent pipe bundle is guaranteed.
